Foot and ankle surgery:Tourniquet placement site to cause as little postoperative pain as possible

There is controversy in the literature on where to place the tourniquet(thigh,calf,ankle)for foot and ankle surgery.While some authors prefer the ankle tourniquet to the calf tourniquet,others state that the surgeon can decide between using the thigh tourniquet or the ankle tourniquet,since there was no difference in postoperative pain between them.Where to place the tourniquet during foot and ankle surgery to cause the least possible postoperative pain to the patient as a result of the tourniquet is a common question in clinical practice.The reality is that,unfortunately,there is no consensus on this issue.Perhaps the only possible way to answer this question would be to conduct a comparative study with sufficient statistical power to reach scientifically sound conclusions.It does not seem easy to carry out such a study,but it would be important to be able to answer the question posed in the title of this Editorial once and for all.

Academic productivity correlates with industry earnings in foot and ankle fellowship programs in the United States:A retrospective analysis

BACKGROUND The study investigates the connection between academic productivity and industry earnings in foot and ankle orthopedic surgery fellowships.Utilizing metrics like the H-index and Open Payments Database(OPD)data,it addresses a gap in understanding the relationship between scholarly achievements and financial outcomes,providing a basis for further exploration in this specialized medical field.AIM To elucidate the trends between academic productivity and industry earnings across foot and ankle orthopedic surgery fellowship programs in the United States.METHODS This study is a retrospective analysis of the relationship between academic productivity and industry earnings of foot and ankle orthopedic surgery fellowships at an individual faculty and fellowship level.Academic productivity was defined via H-index and recorded from the Scopus website.Industry earnings were recorded from the OPD.RESULTS Forty-eight foot and ankle orthopedic surgery fellowships(100%of fellowships)in the United States with a combined total of 165 physicians(95.9%of physicians)were included.Mean individual physician(n=165)total life-time earnings reported on the OPD website was United States Dollar(USD)451430.30±1851084.89(range:USD 25.16-21269249.85;median:USD 27839.80).Mean physician(n=165)H-index as reported on Scopus is 14.24±12.39(range:0-63;median:11).There was a significant but weak correlation between individual physician H-index and individual physician total life-time earnings(P<0.001;Spearman’s rho=0.334)and a significant and moderate positive correlation between combined fellowship H-index and total life-time earnings per fellowship(P=0.004,Spearman’s rho=0.409).CONCLUSION There is a significant and positive correlation between academic productivity and industry earnings at foot and ankle orthopedic surgery fellowships in the United States.This observation is true on an individual physician level as well as on a fellowship level.

Effects of a Cordura Material Ankle-Foot Orthosis on Balance Performance in Patients with Foot Drop

As one of the clinical manifestations in patients with hemiplegia after stroke,most of the patients with foot drop suffer from gait disturbance and balance dysfunction, generally accompanied by strephenopodia. There are relatively few researches on the balance ability of patients with foot drop worldwide,while the balance ability will directly affect the walking ability for recovery,so the research is significant in the rehabilitation of foot drop. In the experiment,the Cordura material ankle-foot orthosis (AFO),one of the world leading technology products,is chosen as the experimental equipment because of its well-known durability and strength. The experiment studied the balance performance of patients with foot drop before and after wearing Cordura material AFO. The Berg scale was evaluated to discuss the effect of the orthosis on balance ability in patients with foot drop. It has been found that the wearing equipment BBS scores were significantly improved. There were significant differences comparing with the control group( P<0.05).But in the course of treatment the Berg balance scale (BBS) scores reduced individually,mainly in terms of leg flexibility.

Examining the intrinsic foot muscles'capacity to modulate plantar flexor gearing and ankle joint contributions to propulsion in vertical jumping

Background:During human locomotion,a sufficiently stiff foot allows the ankle plantar flexors to generate large propulsive powers.Increasing foot stiffness(e.g.,via a carbon plate)increases the ankle’s external moment arm in relation to the internal moment arm(i.e.,increasing gear ratio),reduces plantar flexor muscles’shortening velocity,and enhances muscle force production.In contrast,when activation of the foot’s intrinsic muscles is impaired,there is a reduction in foot and ankle work and metatarsophalangeal joint stiffness.We speculated that the reduced capacity to actively control metatarsophalangeal joint stiffness may impair the gearing function of the foot at the ankle.Methods:We used a tibial nerve block to examine the direct effects of the intrinsic foot muscles on ankle joint kinetics,in vivo medial gastrocnemius’musculotendinous dynamics,and ankle gear ratio on 14 participants during maximal vertical jumping.Results:Under the nerve block,the internal ankle plantar flexion moment decreased(p=0.004)alongside a reduction in external moment arm length(p=0.021)and ankle joint gear ratio(p=0.049)when compared to the non-blocked condition.Although medial gastrocnemius muscle-tendon unit and fascicle velocity were not different between conditions,the Achilles tendon was shorter during propulsion in the nerve block condition(p<0.001).Conclusion:In addition to their known role of regulating the energetic function of the foot,our data indicate that the intrinsic foot muscles also act to optimize ankle joint torque production and leverage during the propulsion phase of vertical jumping.

Perceived barriers and facilitators of day-case surgery for major foot and ankle procedures?A cross-sectional survey of United Kingdom surgeons

BACKGROUND Advances in minimally invasive surgery and improved post-operative pain management make it possible to consider performing even major foot/ankle operations as day-case.This could have significant benefits for patients and the health service.However there are theoretical concerns about post-operative complications and patient satisfaction due to pain.AIM To scope the current practice of foot and ankle surgeons on day-case surgery for major foot and ankle procedures in the United Kingdom(UK).METHODS An online survey(19 questions)was sent to UK foot and ankle surgeons via the British Orthopaedic Foot&Ankle Society membership list in August 2021.Major foot and ankle procedures were defined as surgery that is usually performed as an inpatient in majority of centres and day-case as same day discharge,with day surgery as the intended treatment pathway.RESULTS 132 people responded to the survey invitation with 80%working in Acute NHS Trusts.Currently 45%of respondents perform less than 100 day-case surgeries per year for these procedures.78%felt that there was scope to perform more procedures as day-case at their centre.Post-operative pain(34%)and patient satisfaction(10%)was not highly measured within their centres.Lack of adequate physiotherapy input pre/post-operatively(23%)and lack of out of hours support(21%)were the top perceived barriers to performing more major foot and ankle procedures as day-case.CONCLUSION There is consensus among UK surgeons to do more major foot/ankle procedures as day-case.Out of hours support and physiotherapy input pre/post-op were perceived as the main barriers.Despite theoretical concerns about post-operative pain and satisfaction this was only measured by a third of those surveyed.There is a need for nationally agreed protocols to optimise the delivery of and measurement of outcomes in this type of surgery.At a local level,the provision of physiotherapy and out of hours support should be explored at sites where this is a perceived barrier.

Implications of obesity in patients with foot and ankle pathology

Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2.It is predicted that by 2030,48.9%of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups.This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields.The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies,with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates.In line with increasing interest on the impact of obesity in orthopedics,there has been a similar output of publications in the foot and ankle literature.This review article evaluates several foot and ankle pathologies,their risk factors associated with obesity and subsequent management.It provides an updated,comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes,with the ultimate aim of educating both surgeons and allied health professionals about the risks,benefits,and modifiable factors of operating on obese patients.

Distally based perforator sural flaps for foot and ankle reconstruction

Distally based perforator sural flaps from the posterolateral or posteromedial lower leg aspect are initially a neurofasciocutaneous flap that can be transferred reversely to the foot and ankle region with no need to harvest and sacrifice the deep major artery. These flaps are supplied by a perforating artery issued from the deep peroneal artery or the posterior tibial artery, and the chainlinked adipofascial neurovascular axis around the sural/saphenous nerve. It is a versatile and reliable technique for soft-tissue reconstruction of the heel and ankle region with 180-degrees rotation. In this paper, we present its developing history, vascular basis, surgical techniques including flap design and elevation, flap variations in pedicle and component, surgical indications, and illustrative case reports with different perforating vessels as pivot points for foot and ankle coverage.

The Human Ankle-Foot Complex as a Multi-Configurable Mechanism during the Stance Phase of Walking

The objective of this study is to investigate the biomechanical functions of the human ankle-toot complex during the stancephase of walking. The three-dimensional (3D) gait measurement was conducted by using a 3D infrared multi-camera system anda force plate array to record the Ground Reaction Forces (GRF) and segmental motions simultaneously. The ankle-foot complexwas modelled as a four-segment system, connected by three joints: talocrural joint, sub-talar joint and metatarsophalangeal joint.The subject-specific joint orientations and locations were determined using a functional joint method based on the particleswarm optimisation algorithm. The GRF moment arms and joint moments acting around the talocrural and sub-talar joints werecalculated over the entire stance phase. The estimated talocrural and sub-talar joint locations show noticeable obliquity. Thekinematic and kinetic results strongly suggest that the human ankle-foot complex works as a mechanical mechanism with twodifferent configurations in stance phase of walking. These lead to a significant decrease in the GRF moment arms therebyincreasing the effective mechanical advantages of the ankle plantarflexor muscles. This reconfigurable mechanism enhancesmuscle effectiveness during locomotion by modulating the gear ratio of the ankle plantarflexor muscles in stance. This studyalso reveals many factors may contribute to the locomotor function of the human ankle-foot complex, which include not only itsre-configurable structure, but also its obliquely arranged joints, the characteristic heel-to-toe Centre of Pressure (COP) motionand also the medially acting GRF pattern. Although the human ankle-foot structure is immensely complex, it seems that itsconfiguration and each constitutive component are well tuned to maximise locomotor efficiency and also to minimise risk ofinjury. This result would advance our understanding of the locomotor function of the ankle-foot complex, and also the intrinsicdesign of the ankle-foot musculoskeletal structure. Moreover, this may also provide implications for the design of bionicprosthetic devices and the development of humanoid robots.

Chronic traumatic ankle and foot osteomyelitis: a nationwide case-control study

Background: Osteomyelitis(OM) is an atypical consequence of ankle-foot trauma which is associated with long-term mental and physical morbidity and persistent pain. This study aimed to assess the health status of OM patients with war-related ankle-foot injuries.Methods: A total of 1129 veterans with ankle-foot injuries participated in a case-control study(2014–2016). Thirty patients with chronic OM of the ankle-foot were compared with 90 non-OM participants as the control group. Quality of life(QOL), life satisfaction and the ability to perform basic and instrumental activities of daily living were measured using the following questionnaires: short-form health survey(SF-36), satisfaction with life scale(SWLS), activity of daily living(ADL) and instrumental activity of daily living(IADL), respectively. OM patients were categorized according to their risk factors as A, B and C hosts using a modified version of the Cierny and Mader classification system. The one sample t-test, 2-independent sample t-test, ANOVA, Pearson correlation coefficient and multiple linear regression analyses were applied to analyze the data.Results: Ankle-foot pain leading to surgery(P <0.001) and orthosis usage(P =0.039) were more common in OM patients. There was no significant difference between the two groups in the prevalence of pulmonary and cardiovascular diseases or kidney failure and other related diseases. OM patients showed a significantly lower level of mental health compared to non-OM respondents(P=0.025). Approximately, 70.0% of ankle-foot injured veterans were dissatisfied with their life, and there was no difference between the two groups(P>0.05). Mobility was significantly lower in the OM patients than in the control group(P=0.023). Life satisfaction(P=0.001) and the ability to perform daily activities were the determinants for poor physical(P=0.018) and mental health-related quality of life(P=0.012). According to the Cierny and Mader classification system, they were all included in the type C host classification, with one major and/or three or more minor risk factors.Conclusion: A low level of quality and satisfaction of life and ability to perform activities of daily living were observed in OM patients with war-related ankle-foot injuries. Surgeries of the ankle and foot due to pain were much more common in OM patients than in non-OM participants. Since all the participants were classified as the C-host, health policy planning seems to be necessary.

Foot and ankle history and clinical examination:A guide to everyday practice

This review summarises the key points in taking a history and performing a comprehensive clinical examination for patients with foot and/or ankle problems. It is a useful guide for residents who are preparing for their specialty exams, as well as family doctors and any other doctor who has to deal with foot and ankle problems in adults.

Natural history of sensory nerve recovery after cutaneous nerve injury following foot and ankle surgery

Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Pa- tients received oral vitamin B^2 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory func- tion in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months.

Customized Foot Orthosis Development by 3D Reconstruction of the CT Images

Clinicians can provide a means to better distribute the pressure around the foot, and can also correct the biomechanics of the foot by using a customized shoe insole. If detected early enough, orthopedic insoles can correct or prevent further complications. In this study the 3 Dimensional (D) model of the foot was used to fabricate a customized orthosis. The Computed Tomography (CT) images of patient’s foot having no muscle weakness and joint restriction were acquired. The gray intensities corresponding to the bones of the foot from the CT images were 3 dimensionally reconstructed. The 3D model of the foot was then imported into the CAD Software. Boolean operations were carried out in between the 3D foot model and a solid rectangular surface to create a customized foot orthosis. The exact contours and shape of the subject’s foot was acquired using the computerized method of fabricating an orthosis. The novel idea described in this study support, automating the process of designing a customized orthosis with the impression got from the 3 dimensionally modeled feet, thereby reducing the modeling time considerably. The simple technique used in this process will help in giving comfort and stability to the patient’s feet while walking.

Health-related quality of life and the ability to perform activities of daily living: a cross-sectional study on 1079 war veterans with ankle-foot disorders

Background:The ankle-foot injuries are among the war-related injuries that cause many serious secondary problems for a lifetime.This nationwide study aimed to assess health-related quality of life and the ability to perform activities of daily living in veterans with ankle-foot injuries due to the Iran-Iraq war.Methods:A total of 1079 veterans with ankle-foot injuries were enrolled in a cross-sectional study from 2014 to 2016.Demographic characteristics,including age,gender,marital status,disability percent,educational level,employment and additional injuries,were collected.The ability to perform daily activities was assessed using the Barthel activities of daily living(ADL)and Lawton instrumental activities of daily living(IADL)Indexes.Physical and mental health-related quality of life(HRQOL)data were measured via the SF-36 subscales.The data were compared with those of bilateral lower limb amputees(BLLAs)and of the general Iranian population.Statistical analyses,including Pearson’s correlation coefficient,one-sample t-test and analysis of variance(ANOVA),were performed using SPSS16.0.A multiple linear regression model was used to determine the contribution of independent variables to the Physical Component Summary(PCS)and Mental Component Summary(MCS).Results:The highest and lowest scores were observed for mental health(48.93±20.69)and bodily pain(28.16±21.74),respectively.The mean scores of veterans with ankle-foot injuries on the SF-36 were significantly lower on all eight measures than those of the general Iranian male population and of the bilateral lower limb amputees(P<0.001).The mean scores of ADLs and IADLs were 83.9±16.3 and 5.3±2.0,respectively.The higher dependency in ADLs(P<0.001)and IADLs(P<0.001),the higher disability rate(P<0.001)and additional injury(P<0.001)were significant determinants of the PCS.ADL(P<0.001)and IADL(P<0.001)limitations,additional injury(P<0.001),history of hospitalization in the year preceding the study(P=0.007)and employment(P=0.001)were reported as determinants of the MCS.Conclusion:The results strongly suggest that veterans with ankle-foot injuries suffer from critically poor healthrelated quality of life.The main predicting factors of HRQOL were the disability to perform ADLs/IADLs,suffering two or more injuries,a history of hospitalization in the year preceding the study and unemployment.

Assessment of orthotic needs in Iranian veterans with ankle and foot disorders

Background: War-related traumas can lead to orthopedic and neurological disorders in victims. However, the scope of such disorders may expand months or even years after the trauma. Orthotic treatment as a rehabilitation process aims to enable people with disabilities to reach and maintain their optimal physical, sensory, intellectual, psychological, and social functional levels. This study aimed to investigate the rate of using orthoses among Iranian veterans with neuromuscular and skeletal disorders of the ankle and foot. Furthermore, the priorities of orthotic treatment in those veterans were explored.Methods: This qualitative study was a national health needs assessment conducted in 11 provinces of Iran during 2011–2016. A stakeholder research group was established to survey the veterans in respect to their demographic variables, activities of daily living, current health conditions, and rate of using orthoses.Results: Overall, 907 of the 1124 veteran participants completed the survey(response rate: 80.7%). Most of the veterans were men(97.7%), and their age and disability rate were 52.07±8.13 years and 31.92%±14.93%, respectively. Nearly 42% of the veterans had experience in using orthoses on a daily and weekly basis. As physical ambulation was the main problematic activity in veterans, most of them were using medical shoes and foot orthoses. Nearly 37% of veterans were in need of some type of lower limb orthoses on the contralateral side to compensate for their hip inequality. In sequential order, the most in need orthoses for veterans were foot orthoses(n=538), medical shoes(n=447), lower limb orthoses on the contralateral side(n=320), spinal orthoses(n=273), and upper limb orthoses(n=86).Conclusion: In spite of the high demands for orthoses among Iranian veterans with ankle and foot disorders, the use of orthoses is insufficient. Hence, there is a discrepancy between the current rate of orthoses use and its ideal situation, and more resources should be provided for service providers to be able to serve veterans. Moreover, veterans should be educated regarding orthoses, their use, and their impacts on the user's health status. The findings of a needs assessment of orthoses can be used in strategic planning and decision making to improve health care services for Iranian veterans.

What priorities should be considered for Iranian veterans with ankle-foot injuries？ A health needs assessment study, 25 years post-conflict

Despite the passage of time,a large number of veterans are still affected by injuries acquired during Iran-Iraq war.In addition to their primary injuries,the majority of veterans also experience difficulty with long-term,secondary effects.Studies have shown that the most common of these include a range of disabilities,pain,and dramatic decline in mental health and quality of life.Improving living conditions and providing rehabilitation services to veterans has always been a main priority of authorities.The goal of this study was to explain the methods and materials with which these priorities were explored.

Mental health among Iranian combat veterans with ankle-foot neuromusculoskeletal injuries

Background:Veterans with purely physical disorders,such as ankle-foot neuromusculoskeletal disorders,are often neglected in psychological assessments because mental health evaluations are usually focused on those with a psychological disturbance or with a high percentage of injury.The purpose of this study was to evaluate the psychological condition of veterans with ankle-foot neuromusculoskeletal disorders.Methods:A cross-sectional study was performed between 2014 and 2016 on veterans with war-related ankle-foot injuries living in two provinces of Iran.An information form for demographic data and injury-related factors was used.Additionally,the previously validated Persian version of the Symptom Checklist-90-Revision(SCL-90-R)questionnaire was used for data collection.Results:The respondents were 215 male veterans with a mean age of 51.7±7.5 years.The most common mental health problems were observed for the somatization(24.7%),obsessions-compulsions(14.4%),and anxiety(12.6%).Based on the Global Severity Index(GSI),48.6%of individuals had a possible psychiatric/psychological illness.According to the multivariate regression analysis,GSI scores were significantly higher among veterans who were older than 27 years at the time of injury(P=0.005),had an associated injury(P=0.002),and had a history of hospitalization within the past 12 months for reasons other than their injury(P=0.035).Conclusion:Approximately half of the combat veterans with ankle-foot neuromusculoskeletal disorders likely had psychological problems.The evaluation of the patterns and predicting factors of psychological conditions may inform strategic planning efforts and decision-making,which,in turn,may provide a better quality of life for veterans.Further studies that utilize longitudinal designs are needed to evaluate and compare the psychological status of different groups of veterans and other groups in the general population.

Intraosseous device for arthrodesis in foot and ankle surgery: Review of the literature and biomechanical properties

BACKGROUND Arthrodesis is the surgical fusion of a diseased joint for the purposes of obtaining pain relief and stability.There have been numerous fixation devices described in literature for foot and ankle arthrodesis,each with their own benefits and drawbacks.AIM To review the use of intraosseous devices in foot and ankle surgery.METHODS There were 9 papers included in the review(6 clinical and 3 experimental studies)all evaluating arthrodesis in the foot and ankle using the IOFIX device(Extremity Medical™,Parsippany,NJ,United States).Outcome scores,union rates,as well as complications were analysed.RESULTS IOFIX appears to be safe and effective in achieving arthrodesis of the 1st metatarsophalangeal,and talonavicular joints with early rehabilitation.In comparison to plate/screw constructs there were fewer soft tissue complications and issues of metalwork prominence.Cadaveric and biomechanical studies on the use of intramedullary fixation for fusion of the tarsometatarsal and ankle joint showed decreased load to failure,cycles to failure and stiffness in comparison to traditional fusion methods using plates and screws,however IOFIX devices produced higher compressive forces at the joint.CONCLUSION We describe the reasons for which this biomechanical behavior of the intraosseous fixation may be favorable,until prospective and comparative studies with largersample size and longer follow-up confirm the effectiveness and limitations of the method.

Role of Reversed Sural Artery Flap in Reconstruction of Lower Third of the Leg, Ankle and Foot Defects

Introduction: Coverage of defects of the distal lower extremity and foot remains a challenging reconstructive prcedure. Free tissue transfer remains the standard for the management of these defects. However, there are some disadvantages like;longer operative times, bulky contour, and the need for highly skilled expertise. The reverse superficial sural artery flap (RSSAF) is a distally based fasciocutaneous or adipo-fascial flap that is used for coverage of defects that involve the distal third of the leg, ankle, and foot. A significant advantage of this flap is a constant blood supply that does not require sacrifice of a major artery. Methods: Twenty RSSAF flaps were harvested for reconstruction of different traumatic soft tissue defects of the lower third of leg, ankle and foot. Follow up for 6 months postoperative. Results: Twenty Patients;twelve males and eight females underwent reconstruction of different soft tissue defects over the foot and ankle using RSSAF. The overall complications occurred in 6 flaps;4 minor and 2 major complications. The remaining 14 flaps passed an uneventful follow up. Conclusions: The reverse superficial sural artery flap RSSAF can be used as a reliable alternative to free tissue transfer in reconstruction of defects over the lower third of leg, ankle, and foot. Venous congestion is the major threat to the flap but its incidence can be minimized by wide pedicle, less kink of the flap, and keep the venae comitants around the artery.

Development of a Passive Ankle Foot Prosthesis with Manually Adjustable Ankle Stiffness

Major advancements have been made in the field of prosthetics, but devices remain largely out of reach for the amputee population domiciled in the developing nations, which makes up 80% of the entire amputee population of the world. The amputees are left to contend with low function prosthetics that do not mimic the behavior of the natural lost limb, with the long-term use of such devices leading to physical injury to the user. This work was aimed at developing a low-cost ankle-foot prosthesis that affords the user the opportunity to manually alter the stiffness of the ankle, as well storing energy in a forefoot section to aid push-off in late stance. In this paper, the design and results of structural analysis performed on critical parts of the prosthesis are presented, as well as the future direction of the work.

Applied distally based peroneus brevis muscle flaps for coverage of the soft tissue defects over the lower one-third of the leg, ankle and foot

Objective To investigate a simple, valuable new method for coverage of the soft tissue defect over the lower one-third of the leg, ankle and the foot. Methods The distally based peroneus brevis muscle fkps were applied for coverage of the soft tissue defects over the lower one-third of the leg,the ankle and the foot. The muscle flaps were covered with split-thickness skin grafts. Results The distally based peroneus brevis muscle flaps were applied for coverage of the soft tissue defects over the lower one-third of the leg, the ankle and the foot in 16 cases. The larges area of the soft tissue defect was 5 cm × 7 cm. The smallest was 3 cm × 4 cm. Primary healing occured in 14 cases undergoing muscle flap construction, second-stage healing occured in 2 cases, no total flap necrosis occured in any cases. Conclusion ThisChina Medical Abstracts(Surgery) technigue is a simple and complication are lesser. The successful rates are higher. This muscle flap is suitable to the mudium or small soft tissue
