Abstract
The incidence of open bicondylar Hoffa fractures is extremely rare. We report one such case of a 42-year-old woman who presented to the emergency department with an open injury over the knee. Imaging revealed bicondylar Hoffa fracture. The patient was taken up for debridement and internal fixation. Intraoperative findings included an entrapped patella between the fracture fragments and extensor mechanism disruption. Hoffas fracture was fixed with lag screws and patellar tendon repaired on to the inferior patella. The patient was started on early postoperative range of motion exercises. The fracture united at 12 weeks with 120° knee flexion at 2 year follow-up.
摘要
开放性双髁霍法骨折的发病率极为罕见。我们报告了一例这样的病例，一名42岁女性因膝关节开放性损伤就诊于急诊科。影像学检查显示为双髁霍法骨折。患者接受了清创和内固定手术。术中发现骨折碎片间有髌骨嵌顿以及伸肌机制破坏。双髁霍法骨折用拉力螺钉固定，髌腱修复至髌骨下缘。患者术后早期即开始进行活动度锻炼。骨折在12周时愈合，2年随访时膝关节屈曲达120°。
