Management of soft tissue defects of the thumb

Hand surgery has undergone substantial changes in recent years,especially for reconstructive surgery techniques.We discuss the management of soft tissue defects of the thumb,discussing indications,and operative pearls and pitfalls.We cover non-operative treatment and local advancement flaps for small distal soft tissue defects and pedicled flaps for more significant defects.We also discuss composite vascularized free flaps such as second-toe neurocutaneous flaps and partial hallux transfer for compound defects or total amputations.This article aims to provide hand surgeons with an update on reconstructing an injured thumb.

Versatility of Reverse Sural Fasciocutaneous Flap for Reconstruction of Distal Lower Limb Soft tissue Defects

Summary： In this study we present our experiences with the reverse sural fasciocutaneous flap to reconstruct the distal lower limb soft tissue defects caused by traumatic injuries. These flap graftings were carried out from Oct. 2010 to Dec. 2012 in our department. The series consisted of 36 patients, including 21 men and 15 women with an average age of 46.2 years （14-83 years） and with a medium followp period of 18 months （12-24 months）. Of all the cases of acute trauma, there were 10 eases of trauma of distal tibia, 9 cases of trauma of perimalleolus, and 17 cases of trauma of midfoot and forefoot. Related risk factors in the patients were diabetes （2 cases）, advanced age （〉65 years, 3 cases） and ciga- rette smoking （6 cases）. The reverse flow sural island flap irrigation depended on lower perforators of the peroneal artery. The fasciocutaneous pedicle was 3-4 cm in width and the anatomical structures consisted of the superficial and deep fascia, the sural nerve, short saphenous vein, superficial sural artery together with an islet of subcutaneous cellular tissue and skin. The most proximal border of the flap was only 1.5 cm away from the popliteal skin crease and the pivot point was 5-7 cm above the tip of the lateral malleolus. All the flaps survived. No arterial crisis occurred in any case. The venous congestion occurred in 2 cases and got better after raising the limbs and bloodletting. Only in an old man, 1.5 cm necrosis of distal margin of his flap occurred and finally healed after continuous dressing change. One-stage skin grafting was performed, and all the donor sites were sutured and successfully healed. It was concluded that the reverse sural fasciocutaneous flap is safe and reliable to extend to the proximal third even near the popliteal skin crease. We also concluded this flap can be safely and efficiently used to treat patients with large and far soft-tissue defects from the distal leg to the forefoot with more versatility and it is easier to reach the recipient sites.

Experimental study on early repair of oromaxillofacial perforating soft tissue defect due to gunshot in dogs

The left cheek of 8 adult male mongrel dogs was shot with M1935.56mm bul-let fired through an US-made M16 rifle to result in a perforating soft tissue defect.Pri-mary debridement was performed immediately and the secondary debridement 72h alter in-jury.After the secondary thorough debridement,the cutaneous side of the defect was re-paired with a saphenous artery-vein free skin(muscular)flap using microvascularanastomosis,and the oral side of the defect was repaired by drawing the surroundingmucosa together and fixing with sutures or with a local sliding mucous membrane flap.All the animals were kept under observation for 2～6 months.It was believed that the pri-mary debridement and secondary thorough debridement were both essential. The survivalrate of the free tissue flap was 75%(6/8).These facts suggest that early repair ofthe oromaxillofacial perforating soft tissue defect due to gunshot is practicable.

Soft tissue defects of the hand:etiology and classification

Soft tissue defects of the hand may result from trauma,oncological procedures,or severe infections.Different etiologies have been discussed.In all cases,an accurate clinical examination is mandatory to understand which structures are involved and what must be reconstructed.It can be helpful to simplify the decision-making process to classify these lesions.However,there is no consensus on which classification is best to be used among those described in the literature.This review presents the most common ones,differentiating those classically used to describe tissue loss consequential to a traumatic event from those used to classify soft tissue defects consequent to other events.

Reconstruction of soft tissue defect of the extremity with the perforator flap from inguinal region

Background The perforator flap has become a very useful reconstructive means of soft tissue defect of extremities. The perforator flap from the inguinal region has advantages that include the ability to cover a large area with little donor site morbidity and provision of suitable thickness for reconstruction. Methods From July 1, 2005 to June 30, 2007, 10 patients with various types of soft tissue defect underwent reconstruction with 10 perforator flaps from the inguinal region. Six flaps were applied to the upper extremities and four flaps to the lower extremities. The dimensions of the transferred flaps ranged from 7-30 cm in length and 4-10 cm in width. Results The postoperative course of all 10 flaps was uneventful and all flaps survived. Distal small partial necrosis was observed in one case due to arterial insufficiency of the distal part of the flap. All patients were satisfied with the functional and esthetic resurfacing outcome. Conclusion Use of perforator flap from the inguinal region could overcome the disadvantages of the traditional free groin flap, and represents a safe and useful tool for coverage of soft tissue defects.

Efficacy and safety of external tissue expansion technique in the treatment of soft tissue defects:a systematic review and meta-analysis of outcomes and complication rates

Background:Currently,various external tissue expansion devices are becoming widely used.Considering the scarcity of relevant application standards,this systematic review was performed to explore the effectiveness and safety of external tissue expansion techniques for the reconstruction of soft tissue defects.Method:A systematic review and meta-analysis on the efficacy and safety of external tissue expansion technique was conducted.A comprehensive search was performed in the following electronic databases:PubMed/Medline,Embase,Cochrane Library(Wiley Online Library),andWeb of Science.Studies reporting patients with soft tissue defects under the treatment of external tissue expansion technique were included.Results:A total of 66 studies with 22 different types of external tissue expansion devices met the inclusion criteria.We performed a descriptive analysis of different kinds of devices.A single-arm meta-analysis was performed to evaluate the efficacy and safety of the external tissue expansion technique for different aetiologies.The pooled mean wound healing time among patients with defects after fasciotomy was 10.548 days[95%confidence interval(CI)=5.796-15.299].The pooled median wound healing times of patients with defects after excisional surgery,trauma,chronic ulcers and abdominal defects were 11.218 days(95%CI=6.183-16.253),11.561 days(95%CI=7.062-16.060),15.956 days(95%CI=11.916-19.996)and 12.853 days(95%CI=9.444-16.227),respectively.The pooled wound healing rates of patients with defects after fasciotomy,excisional surgery,trauma,chronic ulcers and abdominal defects were 93.8%(95%CI=87.1-98.2%),97.2%(95%CI=92.2-99.7%),97.0%(95%CI=91.2-99.8%),99.5%(95%CI=97.6-100%),and 96.8%(95%CI=79.2-100%),respectively.We performed a subgroup analysis in patients with diabetic ulcers and open abdominal wounds.The pooled median wound healing time of patients with diabetic ulcers was 11.730 days(95%CI=10.334-13.125).The pooled median wound healing time of patients with open abdomen defects was 48.810 days(95%CI=35.557-62.063)and the pooled successful healing rate was 68.8%(95%CI=45.9-88.1%).A total of 1686 patients were included,265(15.7%)of whom experienced complications.The most common complication was dehiscence(n=53,3.14%).Conclusions:Our systematic review is the first to demonstrate the efficacy and safety of external tissue expansion in the management of soft tissue defects.However,we must interpret the meta-analysis results with caution considering the limitations of this review.Large-scale randomized controlled trials and long-term follow-up studies are still needed to confirm the effectiveness and evaluate the quality of healing.

Consecutive flap transfer for repairing massive soft tissue defects in the opisthenar with improved donor site closure

Objective：To explore a surgical model of utilizing consecutive free scapular flap and adjacent pedicled flap transfer for repairing massive soft tissue defects on the dorsum of the hand while minimizing the donor site morbidity.Methods：Six patients with massive soft tissue injuries on the opisthenar and forearm were treated with free scapular flaps.Afterwards,a pedicled flap adjacent to the donor site was transferred to cover the donor site defect by direct closure.Results：All six free scapular flaps survived without signs of infection.Three adjacent pedicled flaps presented minor signs of insufficient blood flow on the distal apex,which resolved after six weeks with only conservative therapy.All the incisions healed without other complications.At six-month follow-up,the patients regained full shoulder function.Conclusion：With the assistance of an adjacent pedicled flap,the scapular flap is a highly applicable approach in repairing massive soft tissue defects in the opisthenar.It can achieve positive outcomes in both reconstructive and aesthetic aspects.

Effect of a combination of local flap and sequential compression- distraction osteogenesis in the reconstruction of post-traumatic tibial bone and soft tissue defects

Background Treatment of extensive post-traumatic composite bone and soft tissue defects remains a complicated therapeutic problem and a challenge for surgeons. We investigated the application of local flaps and Ilizarov osteogenesis in the reestablishment of severe combined defects of tibial bone and soft tissue. Methods Sixteen patients with bone and soft tissue defects were included. The mean age of the patients was 31.5 years. The average time from injury to initial surgery was 14.4 weeks. The average soft tissue and bone defect sizes were 92.9 cm2 and 8.7 cm, respectively. Local flaps were created to reconstruct the soft tissue defects. The Ilizarov external fixator or the Orthofix Limb Reconstruction System was used to reconstruct bony defects using delayed distraction osteogenesis. Results Two myocutaneous flaps and 14 reverse island flaps were applied. All transferred flaps survived. Fifteen patients healed with equal leg length, and one healed with a residual leg-length discrepancy of 1.5 cm. One patient with an Ilizarov external fixator developed ankle joint stiffening and a pin-track infection that was successfully treated with oral antibiotics. No patient developed pin loosening. All patients walked without assistance. Fifteen patients returned to their work, and one lost her job. The results were evaluated using the Paley bone and functional assessment scores. The bone assessment results were excellent in 14 and good in two patients. Functional assessment scores were excellent in 13, good in two, and fair in one patient. Conclusion The combination of local flaps and sequential distraction osteogenesis can be used for successful reconstruction of defects of incorporated bone and soft tissue.

Reconstruction of post-traumatic upper extremity soft tissue defects with pedicled flaps: An algorithmic approach to clinical decision making

Purpose:Pedicled flaps are still the workhorse flaps for reconstruction of upper limb soft tissue defects in many centers across the world. They are lifeboat options for coverage in vessel deplete wounds. In spite of their popularity existing algorithms are limited to a particular region of upper limb;a general algorithm involving entire upper limb which helps in clinical decision making is lacking. We attempt to propose one for the day to day clinical practice.Methods:A retrospective analysis of patients who underwent pedicled flaps for coverage of post-traumatic upper extremity (arm, elbow, forearm, wrist & hand) soft tissue defects within the period of January 2016 to October 2017 was performed. Patients were divided into groups according to the anatomical location of the defects. The flaps performed for different anatomical regions were enlisted. Demographic data and complications were recorded. An algorithm was proposed based on our experience, with a particular emphasis made to approach to clinical decision making.Results:Two hundred and twelve patients were included in the study. Mean age was 27.3 years (range: 1-80 years), 180 were male, and 32 were female. Overall flap success rate was 98%, the following complications were noted marginal flap necrosis requiring no additional procedure other than local wound care in 32 patients (15%), partial flap necrosis requiring flap advancement or extra flap in 15 patients (7%), surgical site infection in 11 patients (5%), flap dehiscence requiring re-suturing in 5 patients (2.4%), total flap necrosis 4 patients (2%).Conclusion:The proposed algorithm allows a reliable and consistent method for addressing diverse soft tissue defects in the upper limb with high success rate.

Oral and maxillofacial-head and neck reconstruction with soft tissue free flaps of 41 cases: A single team's experience

Objective To retrospectively review the single team's experience of oral and maxillofacialhead and neck reconstruction involving 41 soft tissue free flap procedures.Methods From 1994 to 2012,41 patients who underwent oral and maxillofacial-head and neck soft tissue free flap reconstruction at the Department of Oral and Maxillofacial-Head and Neck Surgical Oncology,Hospital and College of Stomatology,Xi'an Jiaotong University,were reviewed with clinicopathologic data.Results The 41 patients included 24 men and 17 women with a mean age of 54 years.A total of 41 soft tissue free flaps were performed to reconstruct different anatomical structures in the head and neck region including oral mucosa,facial bone,head and neck skin.Two types of soft tissue free flaps were used to reconstruct surgical defects,including radial forearm flap and latissimus dorsi myocutaneous flap.Radial forearm flaps were used for 37cases and latissimus dorsi-myocutaneous flaps were 4 cases.Of 41 cases,39 were successful,with an overall success rate of 95.1%.There were 2 free flap failures,including one radial forearm flap and one latissimus dorsi-myocutaneous flap(partial flap necrosis);hence,the flap success rates for radial forearm flap and latissimus dorsimyocutaneous were,respectively,97.3% and 87.5%.Conclusions Radial forearm flap and latissimus dorsi-myocutaneous flap are reliable soft tissue free flaps to repair oral and maxillofacial-head and neck area with high success rate,which resulted in good functionally and cosmetically with fewer complications both donor and recipient sites.

Application of a pre-filled tissue expander for preventing soft tissue incarceration during tibial distraction osteogenesis

BACKGROUND Bone transport and distraction osteogenesis has been widely used to treat bone defects after traumatic surgery,but,skin and soft tissue incarceration can be as high as 27.6%.AIM To investigate the efficacy of inserting a tissue expander to prevent soft tissue incarceration.METHODS Between January 2016 and December 2018,12 patients underwent implantation of a tissue expander in the subcutaneous layer in the vicinity of a tibial defect to maintain the soft tissue in position.A certain amount of normal saline was injected into the tissue expander during surgery and was then gradually extracted to shrink the expander during the course of transport distraction osteogenesis.The tissue expander was removed when the two ends of the tibial defect were close enough.RESULTS In all 12 patients,the expanders remained intact in the subcutaneous layer of the bone defect area during the course of transport distraction osteogenesis.When bone transport was adequate,the expander was removed and the bone transport process was completed.During the whole process,there was no incarceration of skin and soft tissue in the bone defect area.Complications occurred in one patient,who experienced poor wound healing.CONCLUSION The pre-filled expander technique can effectively avoid soft tissue incarceration.The authors’primary success with this method indicates that it may be a valuable tool in the management of incarcerated soft tissue.
