Abstract:
Objective:To evaluate short-term clinical efficacy of femoral neck system (FNS) for treatment of femoral neck fractures in young and middle-aged patients.Methods:A retrospective analysis was conducted of the 70 middle-aged and young patients who had been surgically treated for femoral neck fractures at Department of Trauma Orthopaedics, Honghui Hospital from January to November 2020. Of them, 32 cases were fixated by FNS; they were 16 males and 16 females, with an age of (49.4±11.0) years, including 10 cases of type Ⅱ, 12 cases of type Ⅲ and 10 cases of type Ⅳ by the Garden classification. The other 38 patients were fixated by cannulated compression screws (CCS); they were 19 males and 19 females, with an age of (48.8±10.1) years, including 12 cases of type Ⅱ, 15 cases of type Ⅲ and 11 cases of type Ⅳ by the Garden classification. The 2 groups were compared in terms of operation time, intraoperative blood loss, fracture reduction, fracture union time, weight-bearing time, complications, Barthel index at 3 months after surgery, and hip function at 6 months after surgery.Results:There was no statistically significant difference in preoperative general information or follow-up time between the 2 groups, showing comparability between groups ( P>0.05). There was no significant difference in operation time, intraoperative blood loss or fracture reduction quality between the 2 groups ( P>0.05). In the FNS group, weight-bearing time [(11.4±3.4) weeks] and fracture healing time [(3.1±0.9) months] were significantly shorter than those in the CCS group [(16.4±3.9) weeks and (3.6±0.9) months], rate of complications (12.5%, 4/32) was significantly lower than that in the CCS group (34.2%, 13/38), Barthel index at 3 months after operation (98.1±2.8) and Harris hip score at 6 months after operation (96.8±4.0) were significantly higher than those in the CCS group (93.8±4.1 and 93.6±6.7) ( P<0.05). Conclusion:In the treatment of femoral neck fractures in young and middle-aged patients, compared with CCS fixation, FNS fixation can obtain better short-term curative effects, due to its advantages of shorter bone union and weight-bearing time, a decreased rate of complications and early functional recovery of daily activities.
