Abstract:
Objective:To compare short-term clinical efficacy between femoral neck system (FNS) and cannulated compression screws (CCS) in the treatment of femoral neck fractures in young adults.Methods:Retrospectively analyzed were the data of 94 patients with femoral neck fracture who had been admitted to Department of Orthopedics and Traumatology, The First Affiliated Hospital to University of Science and Technology of China, Department of Orthopaedics, The First Affiliated Hospital to Anhui Medical University and Department of Orthopaedics, The Second Affiliated Hospital to Anhui Medical University from October 2019 to October 2020. They were divided into 2 groups according to their modes of internal fixation: a FNS group ( n=47) and a CCS group ( n=47). In the FNS group there were 30 males and 17 females with a mean age of (47.8±9.8) years; in the CCS group there were 26 males and 21 females with a mean age of (43.7±13.1) years. The 2 groups were compared in terms of operation time, incision length, intraoperative blood loss, fracture healing time, weight-bearing time, Harris hip score and complications. Results:There was no significant difference in preoperative general data or follow-up duration between the 2 groups, showing comparability between groups ( P>0.05). In the FNS group, operation time [(47.7±9.4) min] was significantly shorter than that in the CCS group [(66.1±3.8) min], postoperative partial and full weight-bearing time [2.0 (2.0, 3.0) weeks, (6.4±2.1) weeks] significantly earlier than that in the CCS group [8.0 (3.0, 9.0), (10.1±3.4) weeks], fracture healing time [3.0(3.0, 4.0) months] significantly shorter than that in the CCS group [3.0(3.0, 4.0) months], Harris hip score at the last follow-up [95.0 (93.0, 95.0) points] significantly higher than that in the CCS group [90.0 (88.0, 95.0) points], incidence of lateral thigh irritation [0% (0/47)] significantly lower than that in the CCS group [31.9% (15/47)], and neck shortening length (4.3±3.9 mm) significantly shorter than that in the CCS group (6.9±4.5 mm) (all P<0.05). There was no significant difference in the rate of avascular necrosis of the femoral head or rate of internal fixation failure between the 2 groups ( P>0.05). Conclusion:In the treatment of femoral neck fractures in young adults, compared with CCS fixation, FNS fixation can shorten operation time and fracture healing time, allow patients to ambulate early after surgery, which is beneficial to maintenance of femoral neck length and to functional recovery of the hip.
