Ankle Fractures, Short Term Operative Outcome: A Retrospective Case Series

Introduction and Background: Ankle injury is one of the most frequent presenting injuries to the emergency room and ankle fractures are common fracture in the lower limbs injuries that may require operative treatment with variable outcomes. Materials and Methods: Sixty-three patients were included in my retrospective study, and all with a displaced fracture of the ankle caused by high energy trauma were treated by open reduction and rigid internal fixation. Results: After follow-up at six weeks and twelve weeks, the results were satisfactory in fifty-five percent out of all the sixty-three patients. Conclusions and Recommendations: Ankle fractures occur mainly in young males of the age group between 26 and 35 years, mostly caused by fall down and motor vehicle accident.

Application Value of Evidence-Based Nursing in the Perioperative Care of Ankle Fracture Patients

Objective:To analyze the value of applying evidence-based nursing in the perioperative care of patients with ankle fractures and propose corresponding measures to improve the quality of patient care.Methods:The study started in May 2022 and was terminated in March 2023.During this period,50 patients with ankle fractures treated by our hospital were selected as research subjects.They were divided into a control group and a research group.The control group had 25 patients who received routine care,and the research group had 25 who received evidence-based care.The nursing effects of the two groups were observed and compared.Results:The pain scores,quality of life,incidence of adverse reactions,and nursing satisfaction of patients in the research group were all significantly better than those in the control group(P<0.05).Conclusion:Evidence-based nursing can effectively improve the quality of care,reduce the risk of adverse reactions,and promote patient recovery,so it is suitable for clinical implementation.

Diagnosing syndesmotic instability in ankle fractures

The precise diagnosis of distal tibiofibular syndesmotic ligament injury is challenging and a distinction should be made between syndesmotic ligament disruption and real syndesmotic instability.This article summarizes the available evidence in the light of the author’s opinion.Pre-operative radiographic assessment,standard radiographs,computed tomography scanning and magnetic resonance imaging are of limited value in detecting syndesmotic instability in acute ankle fractures but can be helpful in planning.Intra-operative stress testing,in the sagittal,coronal or exorotation direction,is more reliable in the diagnosis of syndesmotic instability of rotational ankle fractures.The Hook or Cotton test is more reliable than the exorotation stress test.The lateral view is more reliable than the AP mortise view because of the larger displacement in this direction.When the Hook test is used the force should be applied in the sagittal direction.A force of 100 N applied to the fibula seems to be appropriate.In the case of an unstable joint requiring syndesmotic stabilisation,the tibiofibular clear space would exceed 5 mm on the lateral stress test.When the surgeon is able to perform an ankle arthroscopy this technique is useful to detect syndesmotic injury and can guide anatomic reduction of the syndesmosis.Many guidelines formulated in this article are based on biomechanical and cadaveric studies and clinical correlation has to be established.

Ankle Fractures: A Literature Review of Current Treatment Methods

Ankle fracture is one of the most common lower limb fractures for they account for 9% of all fractures representing a significant portion of the trauma workload. Ankle fractures usually affect young men and older women, however, below the age of 50;ankle fractures are the commonest in men. Two commonly used classification systems for ankle fractures include the danis weber AO classification and the Lauge-Hansen classification. There is biomechanical evidence that posterior non-locking plates are superior in stability than laterally placed plates;however there is little clinical evidence. There are several different methods of ankle fracture fixation, however the goal of treatment remains a stable anatomic reduction of talus in the ankle mortise and correction of the fibula length as a 1 mm lateral shift of the talus in the ankle mortise reduces the contact area by 42%, and displacement (or shortening) of the fibula more than 2 mm will lead to significant increases in joint contact pressures. Further research both biomechanically and clinically needs to be undertaken in order to clarify a preferable choice of fixation.

Acute syndesmotic injuries in ankle fractures:From diagnosis to treatment and current concepts

A stable and precise articulation of the distal tibiofibular syndesmosis maintains the tibiofibular relationship,and it is essential for normal motion of the ankle joint.The disruption of this joint is frequently accompanied by rotational ankle fracture,such as pronation-external rotation,and rarely occurs without ankle fracture.The diagnosis is not simple,and ideal management of the various presentations of syndesmotic injury remains controversial to this day.Anatomical restoration and stabilization of the disrupted tibiofibular syndesmosis is essential to improve functional outcomes.In such an injury,including inadequately treated,misdiagnosed and correctly diagnosed cases,a chronic pattern characterized by persistent ankle pain,function disability and early osteoarthritis can result.This paper reviews anatomical and biomechanical characteristics of this syndesmosis,the mechanism of its acute injury associated to fractures,radiological and arthroscopic diagnosis and surgical treatment.

Ankle Arthroscopy: A Complimentary Adjunct in the Diagnosis and Management of Ankle Fractures

Ankle fractures are one of the most common injuries treated by orthopaedic surgeons. A minority of patients with ankle fractures go on to develop persistent pain following anatomical reduction. These sequelae may arise as a result of untreated ligamentous or chondral injuries. This study aims to correlate acute arthroscopic ankle findings with the Lauge-Hansen fracture pattern classification. We further aim to compare subjective functional outcomes at least one year following surgery between patients who have received Open Reduction and Internal Fixation (ORIF) alone, versus ORIF plus arthroscopy. This is a retrospective case series of patients who have undergone ankle fracture ORIF +/- arthroscopy from July 2014 to July 2017 inclusive. Each patient’s presenting radiograph was classified according to the Lauge-Hansen ankle fracture classification with subsequent correlation to intra-operative arthroscopic findings. Functional outcome at a minimum of one year was evaluated with the American Academy of Orthopaedic Surgeons (AAOS) metric. Twenty two patients underwent ankle ORIF plus arthroscopy (Group A) with a further 26 patients receiving ORIF alone (Group B). 1 in 3 supination-external-rotation type II (SER II) injuries possessed a concomitant syndesmosis injury or osteochondral lesion (OCL) on arthroscopy. 1 in 3 patients with an SER IV injury had an osteochondral lesion. The mean AAOS score achieved for Group A was 89.6 (±7.9) with the mean score for Group B being 82.0 (±13.7). In conclusion, ankle arthroscopy aids the diagnosis and treatment of ligamentous and osteochondral injuries not evident on plain film with subsequent superior short-term outcomes.

Ankle Arthrodesis Nail Combined with Locking Compression Plate to Stabilize Two-Level Pathologic Tibial Fractures

Treatment of fragility fractures of the distal tibia in the elderly is demanding because of osteopenic bone quality, the delicate soft tissue cuff and frequent critical circulation. We report the case of two-level tibial pseudarthroses in an 83- year-old woman caused by multiple myeloma successfully stabilized by a long ankle arthrodesis nail combined with locking compression plate osteosynthesis. This case is unique, as to our best knowledge, herein diaphyseal fractures were treated for the first time using a technique reported hitherto primarily for fragility ankle and pilon fractures.

Ankle Arthrodesis in the Treatment of Neglected Ankle Fractures

Introduction: Neglected ankle fractures are common in our regions. Patients first consult traditional healers and it is when the signs persist that they consult the surgeon for a swollen and painful ankle. Initially we always performed anatomical repairs with osteosynthesis, but the majority of patients still complained of pain and disability. We wondered whether a primary arthrodesis would not be indicated in old ankle fractures to avoid disabling pain for patients. We therefore performed a series of arthrodesis on neglected post-traumatic ankles. The objective of our study was to describe the results of arthrodesis on an old post-traumatic ankle and to propose a therapeutic indication in the face of any neglected ankle fracture. Material and Method: This was a prospective study over 8 years between December 2012 and November 2020, involving 36 cases of neglected ankle fractures treated by arthrodesis using Meary’s technique. We used AOFAS (American Orthopedic Foot and Ankle Score) preoperatively and postoperatively for an objective assessment. Results: The average follow-up was 4.2 years and our results were satisfactory (94.4%) with an average AOFAS score ranging from 27.8 preoperatively to 76.7 postoperatively. The fusion rate was 97.2%. Discussion: Arthrodesis appears here as an important alternative in the treatment of neglected ankle fractures with significant trophic disorders.

Application of computer aided 3D simulation technique for complicated foot and ankle fractures

Objective To investigate the effect of computer aided 3D simulation technique for treating complicated foot and ankle fractures precisely.Methods From November 2007 to August 2009,255 patients with complicated foot and ankle fractures

Locking plates for distal fibula fractures in young and elderly patients:A retrospective study

BACKGROUND Ankle fractures are common injuries in the young and elderly populations.To prevent post-traumatic arthritis,an anatomic reconstruction of the ankle structure is mandatory.Open reduction and internal fixation is the treatment of choice among orthopaedics.Conventional plates allow stability of the fracture if bone quality is present.Locking plates might offer an advantage for the treatment of lateral malleolar fracture in patients with comminution,severe instability,distal fractures,or osteoporotic bone.Our hospital introduced a new locking plate for fracture of the distal fibula.AIM To evaluate locking plates in terms of outcomes and complications in young and elderly patients.METHODS We retrospectively reviewed a total of 67 patients treated for displaced distal fibula fractures.Demographic data,number of comorbidities,use of inter fragmentary screw,complication,time of fracture healing,partial or full weight bearing,and reoperation were recorded for all patients.Clinical outcome was assessed by the American Orthopedic Foot and Ankle Society clinical scoring system.Radiographs were obtained at 4,8,12,16,20,and 24 wk until radiographic union was obtained.RESULTS All patients displayed complete bony union on radiographic assessment,and no patients developed any serious complications.We observed two superficial infections,one delayed wound healing,and two plate intolerances.Significant differences were observed between the two age groups in terms of radiographic healing(11.9 wk in younger patients vs 13.7 wk in older patients;P=0.011)and in the American Orthopedic Foot and Ankle Society score at 6 mo after surgery(88.2 in younger patients vs 86.0 in older patients;P=0.001)and at 12 mo after surgery(92.6 in younger patients vs 90.0 in older patients;P=0.000).CONCLUSION Locking plates provide a stable and rigid fixation in multifragmentary and comminuted fractures or in the presence of poor bone quality.

Ankle fracture configuration following treatment with and without arthroscopic-assisted reduction and fixation

AIM: To report ankle fracture configurations and bone quality following arthroscopic-assisted reduction and internal-fixation(ARIF) or open reduction and internalfixation(ORIF). METHODS: The patients of ARIF(n = 16) or ORIF(n = 29) to treat unstable ankle fracture between 2006 and 2014 were reviewed retrospectively. Baseline data, including age, sex, type of injury, immediate postoperative fracture configuration(assessed on X-rays and graded by widest gap and largest step-off of any intraarticular site), bone quality [assessed with bone mineral density(BMD) testing] and arthritic changes on X-rays following surgical treatments were recorded for each group.RESULTS: Immediate-postoperative fracture configurations did not differ significantly between the ARIF and ORIF groups. There were anatomic alignments as 8(50%) and 8(27.6%) patients in ARIF and ORIF groups(P = 0.539) respectively. There were acceptable alignments as 12(75%) and 17(58.6%) patients in ARIF and ORIF groups(P = 0.341) respectively. The arthritic changes in follow-up period as at least 16 wk following the surgeries were shown as 6(75%) and 10(83.3%) patients in ARIF and ORIF groups(P = 0.300) respectively. Significantly more BMD tests were performed in patients aged > 60 years(P < 0.001), ARIF patients(P = 0.021), and female patients(P = 0.029). There was no significant difference in BMD test t scores between the two groups. CONCLUSION: Ankle fracture configurations following surgeries are similar between ARIF and ORIF groups, suggesting that ARIF is not superior to ORIF in treatment of unstable ankle fractures.

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.

Importance of computed tomography in posterior malleolar fractures:Added information to preoperative X-ray studies

BACKGROUND Ankle fractures are common lesions of the lower limbs.Approximately 40%of ankle fractures affect the posterior malleolus(PM).Historically,PM osteosynthesis was recommended when PM size in X-ray images was greater than 25%of the joint.Currently,computed tomography(CT)has been gaining traction in the preoperative evaluation of ankle fractures.AIM To elucidate the similarity in dimensions and to correlate PM size in X-ray images with the articular surface of the affected tibial plafond in the axial view on CT(AXCT)of a PM fracture.METHODS Eighty-one patients(mean age:39.4±13.5 years)were evaluated(54.3%were male).Two independent examiners measured PM size in profile X-ray images(PMXR)and sagittal CT(SAGCT)slices.The correlation of the measurements between the examiners and the difference in the PM fragment sizes between the two images were compared.Next,the PM size in PMXR was compared with the surface of the tibial plafond involved in the fracture in AXCT according to the Haraguchi classification.RESULTS The correlation rates between the examiners were 0.93 and 0.94 for PMXR and SAGCT,respectively(P<0.001).Fragments were 2.12%larger in SAGCT than in PMXR(P=0.018).In PMXR,there were 56 cases<25%and 25 cases≥25%.When PMXR was<25%,AXCT corresponded to 10.13%of the tibial plafond.When PMXR was≥25%,AXCT was 24.52%(P<0.001).According to the Haraguchi classification,fracture types I and II had similar PMXR measurements that were greater than those of type III.When analyzing AXCT,a significant difference was found between the three types,with II>I>III(P<0.001).CONCLUSION PM fractures show different sizes using X-ray or CT images.CT showed a larger PM in the sagittal plane and allowed the visualization of the real dimensions of the tibial plafond surface.

Fibula pro-tibia vs standard locking plate fixation in an ankle fracture saw bone model

BACKGROUND Locking plate fixation in osteoporotic ankle fractures may fail due to cut-out or metalwork failure.Fibula pro-tibia fixation was a technique prior to the advent of locking plates that was used to enhance stability in ankle fractures by achieving tri or tetra-cortical fixation.With locking plates,the strength of this fixation construct can be further enhanced.There is lack of evidence currently on the merits of tibiapro-fibula augmented locking plate fixation of unstable ankle fractures.AIM To assess if there is increased strength to failure,in an ankle fracture saw bone model,with a fibula pro-tibia construct when compared with standard locking plate fixation.METHODS Ten osteoporotic saw bones with simulated supination external rotation injuries were used.Five saw bones were fixed with standard locking plates whilst the other 5 saw bones were fixed with locking plates in a fibula pro-tibia construct.The fibula pro-tibia construct involved fixation with 3 consecutive locking screws applied across 3 cortices proximally from the level of the syndesmosis.All fixations were tested in axial external rotation to failure on an electromagnetic test frame(MTS 858 Mini-Bionix test machine,MTS Corp,Eden Praire,MN,United States).Torque at 30 degrees external rotation,failure torque,and external rotation angle at failure were compared between both groups and statistically analyzed.RESULTS The fibula pro-tibia construct demonstrated a statistically higher torque at 30 degrees external rotation(4.421±0.796 N/m vs 1.451±0.467 N/m;t-test P=0.000),as well as maximum torque at failure(5.079±0.694N/m vs 2.299±0.931 N/m;t-test P=0.001)compared to the standard locking plate construct.The fibula pro-tibia construct also had a lower external rotation angle at failure(54.7±14.5 vs 67.7±22.9).CONCLUSION The fibula pro-tibia locking plate construct demonstrates biomechanical superiority to standard locking plates in fixation of unstable ankle fractures in this saw bone model.There is merit in the use of this construct in patients with unstable osteoporotic ankle fractures as it may aid improved clinical outcomes.

The Effect of Percutaneous Screw Fixation of Lateral Malleolus on Ankle Fracture Healing and Function

Purpose: To measure the effectiveness of using percutaneous intramedullary screw fixation of the lateral malleolus fracture on the healing and functional outcome of ankle fracture. Materials and methods: Forty-six patients with Weber A and low Weber B displaced lateral malleolus fractures who underwent closed reduction and percutaneous internal fixation with an intramedullary, fully threaded, screw were retrospectively reviewed. A 3.5-mm, fully threaded, selftapping bone screw (stainless steel from Pelvic Set Synthes). The length of the screw varies between 100 mm and 120 mm, depending on the fracture location and pattern. Results: All fractures united within an average time to union of 8.2 weeks. In all patients the average time to full weight bearing was 6.8 weeks, whereas that in patients with isolated lateral malleolus fractures was 4.5 weeks. There were no deep wound infections or complaints of painful hardware. At latest follow-up, functional results were excellent in, 25 patients (54.3%) good in 20 (43.5%), fair in (2.2%). Conclusion: If reduction of the lateral malleolus fracture can be obtained in a closed fashion (with the aid of an image x-ray intensifier), we believe that fixation may be performed with an axial screw percutaneously. This technique is quick, safe and easy to do with less complication.

Three-dimensional computed tomography mapping of posterior malleolar fractures

BACKGROUND Posterior malleolar fractures have been reported to occur in<40%of ankle fractures.AIM To reveal the recurrent patterns and characteristics of posterior malleolar fractures by creating fracture maps of the posterior malleolar fractures through the use of computed tomography mapping.METHODS A consecutive series of posterior malleolar fractures was used to create threedimensional reconstruction images,which were oriented and superimposed to fit an ankle model template by both aligning specific biolandmarks and reducing reconstructed fracture fragments.Fracture lines were found and traced in order to generate an ankle fracture map.RESULTS This study involved 112 patients with a mean age of 49,comprising 32 pronationexternal rotation grade IV fractures and 80 supination-external rotation grade IV fractures according to the Lauge-Hansen classification system.Three-dimensional maps showed that the posterior ankle fracture fragments in the supinationexternal rotation grade IV group were relatively smaller than those in the pronation-external rotation grade IV group after posterior malleolus fracture.In addition,the distribution analyses on posterior malleolus fracture lines indicated that the supination-external rotation grade IV group tended to have higher linear density but more concentrated and orderly distribution fractures compared to the pronation-external rotation grade IV group.CONCLUSION Fracture maps revealed the fracture characteristics and recurrent patterns of posterior malleolar fractures,which might help to improve the understanding of ankle fracture as well as increase opportunities for follow-up research and aid clinical decision-making.

Fibula fractures management

Isolated distal fibula fractures represent the majority of ankle fractures.These fractures are often the result of a low-energy trauma with external rotation and supination mechanism.Diagnosis is based on clinical signs and radiographic exam.Stress X-rays have a role in detecting associated mortise instability.Management depends on fracture type,displacement and associated ankle instability.For simple,minimally displaced fractures without ankle instability,conservative treatment leads to excellent results.Conservative treatment must also be considered in overaged unhealthy patients,even in unstable fractures.Surgical treatment is indicated when fracture or ankle instability are present,with several techniques described.Outcome is excellent in most cases.Complications regarding wound healing are frequent,especially with plate fixation,whereas other complications are uncommon.

The damage control in tibial pilon open fractures with a new external fixator delta frame

Objective: To evaluate the effectiveness of the damage control, in emergency to treat the open tibial pilon fractures with Dolphix? External Fixator Frame(CITIEFFE?, Calderara di Reno, Bologna, Italy). Methods: From January 2017 to August 2017, at the Department of Orthopedics and Traumatology of Vito Fazzi Hospital Lecce, we treated 23 open tibial pilon fractures with Dolphix? External Fixator Frame(CITIEFFE?, Calderara di Reno, Bologna, Italy). The evaluation criteria of the case series were: the time needed to assemble the external fixator;the time taked to treat the ankle associated lesions;the time of skin healing;the ankle alignment;the subjective/objective Ovadia and Beals score;and complications. The Endpoint assessment was set at the days of the definitive surgery. Results: The results in terms of alignment, biomechanical stability of the frame, healing of soft tissue, complications were as good as the objective and subjective results according Ovadia and Beals score. Conclusion:Pilon fractures are complex and often present complications;the damage control treatment, in emergency, with Dolphix? External Fixator Frame(CITIEFFE?, Calderara di Reno, Bologna, Italy) permits a stable osteotaxis with minimal soft tissue damage and permit the repair of muscles, blood vessels and nerves with a stable bone and the soft tissue healing with vaccum therapy.

The Use of Human Amniotic Allograft on Osteochondritis Dissecans of the Talar Dome: A Comparison with and without Allografts in Arthroscopically Treated Ankles

Arthroscopy of the ankle with micro-fracture technique is one way to initially treat symptomatic talar dome lesions. Human amniotic allograft has been used in similar bone, soft tissue and cartilage defects to aid in healing of tissue using graft cells that have not differentiated into a particular cell line. Patients were taken from the primary surgeon’s practice to include those who had undergone arthroscopy with micro-fracture technique for treatment of a talar dome lesion less than 2 cm2. 101 patient surgeries were completed arthroscopically without additional major procedures. 54 surgeries were completed with human amniotic allograft;47 were completed without (control group). Modified ACFAS ankle scores were taken pre-operatively, 3, 12 and 24 months post-operatively. Visual analog pain scores were taken pre-operatively and 24 months post-operatively. Results comparing pre-operative modified ACFAS scores between the control and graft groups were not significantly different (p = 0.14). There was a significant improvement in both groups’ scores following ankle arthroscopy with micro-fracture as expected. However, the amniotic tissue group did significantly better when comparing the post-operative scores between the control and graft group. Pain scores comparing control and amniotic patient groups were significant (p < 0.001) with amniotic allograft patients achieving a greater improvement in pain reduction than the control both early and at 24 months. There were no complications, wound dehiscence or infections recorded. Combining ankle arthroscopy/micro-fracture technique with human amniotic allograft on talar dome lesions, less than 2 cm2, significantly improves the patients’ pain and ACFAS scores.
