Double posterior lateral plating arthrodesis for charcot ankle: A case series.

ABSTRACT:

Introduction

Ankle arthrodesis is one of the managements for a significantly unstable Charcot ankle. Some of the methods of internal fixation for ankle arthrodesis include the use of intramedullary nails, screws, and plates. Ankle arthrodesis using intramedullary nails has become more popular. However, studies evaluating the use of plate fixation, particularly double posterior lateral plating, are limited. We report the clinical and radiological outcomes of double posterior lateral plating ankle arthrodesis in three diabetic Charcot ankle patients.

Presentation of case

Three patients, aged 73, 67, and 65 years old, complained of ankle pain and with a history of type 2 diabetes mellitus. The physical examination revealed swelling and erythema without a sign of active infection. The radiological examination showed ankle deformity, and the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot scores were 5, 10, and 0, respectively. All patients were diagnosed with a diabetic Charcot ankle and underwent ankle arthrodesis using double posterior lateral plating. Four months and six months follow up revealed talus union, improved ankle deformity, and improved AOFAS Ankle-Hindfoot scores to 70, 76, and 73, respectively.

Discussion

Various methods of ankle arthrodesis are retrograde intramedullary nails, screws, and plates. In this report, we opt for plate fixation because it allows for stable internal fixation, adequate compression, high angular stability, and a lower irreversible deformation in osteoporotic bone.

Conclusion

Double posterior lateral plating ankle arthrodesis provided satisfactory clinical and radiological outcomes. This method can be an alternative for patients with Charcot ankle requiring ankle arthrodesis.

Project description:BackgroundTreatment of ankle fractures in patients with diabetes is associated with increased complication rates. Ankle arthrodesis is considered a salvage procedure after failed ankle fracture fixation, yet primary ankle arthrodesis has been proposed as a treatment option for patients with significant diabetes-related complications. To date, the characteristics of patients who undergo primary ankle arthrodesis and the associated outcomes have not been described.MethodsA retrospective review was performed of 13 patients with diabetes who underwent primary arthrodesis for traumatic ankle fracture. Patient demographics were characterized in addition to their diabetes complications, Adelaide Fracture in the Diabetic Ankle (AFDA) score, and fracture type. Outcomes assessed included reoperation rates, infection rates, wound complications, nonunion/malunion, amputation, and development of Charcot arthropathy postoperatively.ResultsPatients who underwent primary arthrodesis had high rates of diabetes complications, average AFDA scores of 6.4, and high rates of severe injuries, including 38.5% open fractures and 69.2% fracture dislocations. The overall complication rate for primary arthrodesis of ankle fractures in diabetes patients was more than 75% in this cohort. Complications included a 38.5% reoperation rate, 38.5% infection rate, 53.8% wound complication rate, and 23.1% amputation rate. Despite a high nonunion rate at the attempted fusion sites, 89.9% of fractures healed and patients had a stable extremity.ConclusionThis review is the first to characterize the epidemiology and complications of diabetes patients undergoing primary ankle arthrodesis for ankle fractures. In this cohort, patients with multiple diabetic complications and severe injuries underwent primary arthrodesis, which led to an overall high complication rate. Further research is needed to determine the appropriate treatment option for these high-risk patients, and tibiotalocalcaneal stabilization without arthrodesis may be beneficial.Level of evidenceLevel IV, retrospective case series.

Project description:BackgroundBipolar clavicle injury is a rare injury involving any combination of dislocation and/or fracture at both ends of the clavicle. Most reports of bipolar clavicle injury have been based on a single case, and treatment of this injury remains controversial. The present study was performed to evaluate the efficacy of surgical management with internal plating for bipolar clavicle injuries.MethodsWe performed internal plating to treat seven consecutive bipolar clavicle injuries with different injury patterns from May 2013 to June 2021. A clavicle hook plate was used for five sternoclavicular joint injuries (including a revision surgery) and three acromioclavicular joint dislocations, a T plate was used for one sternoclavicular joint injury, and an anatomic plate was used for one distal clavicle fracture. At follow-up, radiographs were assessed for bone alignment, joint congruity, fracture union or malunion, and implant failure or migration. Clinical evaluation included determination of the Disability of the Arm, Shoulder, and Hand (DASH) score; Constant-Murley score; visual analog scale (VAS) score; and complications.ResultsThe patients were regularly followed up after the operation, and functional parameters were assessed over time. At a mean follow-up of 28.1 ± 22.0 months, each fracture had solid bone union, and each dislocation showed no sign of recurrent instability. The mean shoulder forward flexion was 159.3° ± 7.9°, and the mean DASH score was 8.8 ± 5.1. The mean Constant-Murley score was 88.9 ± 7.9, with six cases assessed as excellent and one case assessed as good. The mean VAS score was 1.0 ± 1.5, and the mean patient satisfaction score was 9.3 ± 0.8. No complications occurred, and each patient was able to resume their preinjury daily activity and was highly satisfied with their treatment.ConclusionsIn the present study, internal plating for bipolar clavicle injury allowed early mobilization and resulted in good joint function. We recommend fixation of the more severely affected side first because the other side may be passively reduced and acquire stability once the more severely affected side has been fixed. Internal fixation of the other end may therefore be unnecessary unless residual instability exists.
