RESUMO
Objective:To compare the short-term efficacy between femoral neck system (FNS) and cannulated compression screws (CCS) in the treatment of femoral neck fractures in young and middle-aged patients.Methods:A retrospective study was performed of the 29 young and middle-aged patients with femoral neck fracture who had been treated with FNS at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2020 to December 2020. A control group of another 29 patients with femoral neck fracture was selected who had been treated with CCS but matched in gender, age, and body mass index. In the CCS group, there were 14 males and 15 females with an age of (48.2±12.3) years; in the FNS group, there were 14 males and 15 females with an age of (48.2±12.0) years. The fracture reduction quality, operation time, intraoperative blood loss, and femoral neck shortening, hip joint function, Barthel index and health survey 12-item short form (SF-12) score at the last follow-up and complications during follow-up were compared between the 2 groups.Results:No significant difference was found in the preoperative general data or follow-up time between the 2 groups, showing comparability ( P>0.05). The intraoperative blood loss in the CCS group [20 (10, 50) mL] was significantly less than that in the FNS group [50 (20, 50) mL], and the femoral neck shortening at the last follow-up in the CCS group (grade 1 in 5 cases; grade 2 in 18 cases and grade 3 in 6 cases) was significantly worse than that in the FNS group (grade 1 in 21 cases, grade 2 in 6 cases and grade 3 in 2 cases) ( P<0.05). No significant difference was found regarding fracture reduction quality, operation time, complications during follow-up, or Merle D'Aubigne Postel score, Barthel index or SF-12 score at the last follow-up ( P>0.05). Conclusions:In the treatment of femoral neck fractures in young and middle-aged patients, both FNS and CCS are good options for internal fixation. However, FNS can reduce the severity of femoral neck shortening and maintain the length of femoral neck better than CCS.
RESUMO
Objective To retrospectively analyze the clinical results of peroneal tendon insertion and reconstruction with suture anchors in the treatment of avulsion fractures of the fifth metatarsal base.Methods Five patients (three males and two females) with the fifth metatarsal base fractures were in zone 1, with average seven days of duration before surgery. The result of radiological examination confirmed that all fractures were in zone 1 of the fifth metatarsal base, with some small, comminuted and obviously displaced pieces. After removal of the small comminuted fracture pieces, the peroneal tendon insertion was dissociated and sutured to the fifth metatarsal base by suture anchors (5 mm in diameter) with line. The feet were immobilized by plaster in the vagus position. The patients began to walk with weightbearing six weeks after operation. Results All patients were followed up for at least six months, which showed no deformity of the feet. The function of forefoot valgus and abduction restored to normal. There was no any loss in muscle force compared with the normal side. Conclusions Peroneal tendon insertion and reconstruction by suture anchors is very helpful to solve the problem in the fixation of the small fracture fragments. The function of the peroneal tendon recovers very well. The surgery has the advantages of easy manipulation and small area of dissection, without requirement of secondary surgery.
