RESUMO
INTRODUCTION AND IMPORTANCE: In rare cases of ankle fracture dislocation, PTT can be incarcerated in the ankle syndesmosis. We report a case of a patient who had a fracture-dislocation of the ankle with the interposition of PTT in the ankle syndesmosis and discuss a systematic review of injury mechanics, pathology, diagnosis, management, and outcomes of this injury. CASE PRESENTATION: I reported a 43-year-old patient presented with an irreducible lateral displacement of the talus after ORIF of the malleolar ankle fractures and fixation of ankle syndesmosis. Subsequent open reduction and surgical management revealed an interposition of PTT in the syndesmosis 1- month post-operative. A systematic review was completed afterward with the following terms: "ankle fracture" OR "ankle dislocation" AND "tibialis posterior tendon interposition" OR "tibialis posterior tendon entrapment" OR "tibialis posterior tendon incarceration" on Medline, ScienceDirect, and Ovid for articles between 1970 and 2022. CLINICAL DISCUSSION: 5 months postoperative, the patient reported no pain and became capable of walking without a steppage gait. The systematic review showed that the entrapment of PTT could be concurrent with FHL, FDL, and tibial neurovascular. It usually occurs in patients with pronation/eversion injury, Weber C ankle fracture with a valgus deformity and a syndesmosis diastasis. CONCLUSION: The PTT entrapment usually occurs in patients with pronation/eversion injury, Weber C ankle fracture, a valgus deformity, a syndesmosis diastasis. The entrapment of PTT could be concurrent with FHL, FDL, and tibial neurovascular. The tibiofibular syndesmosis and retromalleolar groove should be explored intraoperatively with suspicion of irreducible ankle fracture-dislocations.
RESUMO
BACKGROUND: The purpose of this study was to assess the functional, psychological outcomes and complications of bilateral tibial lengthening over intramedullary nail. The intramedullary nail in this study was the Surgical Implant Generation Network (SIGN) nail. MATERIAL AND METHODS: We enrolled patients desiring stature lengthening at the 108 Military Central Hospital (Hanoi, Vietnam) from October 2011 to January 2019. A total of 104 people have been enrolled in the study and underwent the bilateral tibial lengthening procedure. RESULTS: Average tibial lengthening was 7.1 ± 0.8 cm in men and 6.5 ± 0.6 cm in women. Percentage of tibial lengthening as compared with tibia length at the time of pre-operation was 23.9 ± 3.5% for male patients and 21.5 ± 3.7% for female patients. The outcome was excellent in 85 patients (81.7%) and good in 19 (18.3%). All patients experienced improved self-esteem and enhanced quality of life. CONCLUSION: Our study suggests that bilateral tibial lengthening over nail was safe and effective provided complications are looked for and kept in check. Equinus contracture, pin tract infection, and valgus deviation were the most common complications. Valgus deviation occurs during distraction period. In patient who had neutral or valgus alignment, we recommend to use a blocking screw at the proximal segment post-operatively and use a blocking screw at the valgus distal segment at the end of distraction period to maintain the mechanical axis of both tibias. Bilateral tibial lengthening over nail should be widely employed in low-income countries.
