Abstract:
Objective:To explore the short-term therapeutic outcomes of femoral neck fractures fixated by Femoral Neck System (FNS).Methods:A retrospective analysis was conducted of the 16 patients with femoral neck fracture who had been admitted to the Department of Traumatology & Orthopedics, The Second Affiliated Hospital to Anhui Medical University from January to December 2019. They were 6 males and 10 females, aged from 24 to 69 years (average, 47.5 years). According to the Garden Classification, there were 3 cases of type Ⅱ, 7 cases of type Ⅲ, and 6 cases of type Ⅳ. All the 16 patients were fixated with FNS. Recorded were operation time, frequency of intraoperative fluoroscopy, intraoperative blood loss, quality of postoperative fracture reduction, hospital stay, fracture healing time, and efficacy and complications at the last follow-up.Results:The 16 patients were followed up for 5 to 16 months after operation (average, 9.3 months). According to the Garden indexes, fracture reduction was evaluated as satisfactory in all the 16 patients. The operation time in this group ranged from 25 to 115 min with an average of 41.5 min, the frequency of intraoperative fluoroscopy from 14 to 47 times with an average of 26 times, the intraoperative blood loss from 35 to 210 mL with an average of 76 mL, the hospital stay from 3 to 9 days with an average of 4.6 days, and the fracture healing time from 3 to 6 months with an average of 4.5 months. By the Harris hip scores at the last follow-up, the function of the affected hip was rated as excellent in 10 cases, good in 5 and fair in one. Follow-ups revealed no complications like infection or implant loosening.Conclusions:The FNS is a new type of simple, reliable, safe and minimally invasive internal fixation for the treatment of femoral neck fractures. The plate, bolt, anti-rotation screws and locking screws in FNS can be inserted through a single minimally invasive incision, leading to reliable fixation, limited irritation to the lateral muscular soft tissues, and fine short-term outcomes.
