Abstract
BackgroundFemoral neck fractures are one of the problems in clinical treatment. The prognosis is uncertain. Currently, No internal fixation method is superior to other internal fixation methods in the treatment of femoral neck fractures. Therefore, the internal fixation system needs to be further explored. The aim of this study was to compare clinical outcomes of femoral neck dynamic compression locking system (DCLS) and multiple cannulated compression screws(MCCS) in the treatment of femoral neck fractures.MethodsA prospective analysis of 54 cases of femoral neck fractures treated with either a DCLS (n = 28) or MCCS (n = 26) was conducted between December 2015 and November 2017 in authors’ hospitals. The perioperative and postoperative parameters of the two groups were recorded and evaluated.ResultsFifty-four patients were followed up for 24–47 months. The etiology was caused by a fall. There was no significant difference in follow-up time, operation time, incision length, surgical blood loss, the incidence of perioperative and postoperative healing complications, and mobility in the two groups (all P > 0.05). The Harris score, fracture healing time, femoral neck shortening, partial weight-bearing time and complete weight-bearing time were significantly better in the DCLS group than in the MCCS group (all P < 0.05). The fracture healing rate in the DCLS group was higher than that in the MCCS group.ConclusionsThe DCLS and MCCS might be equally effective in terms of operation time, incision length, surgical blood loss, the incidence of perioperative and postoperative healing complications, and mobility in the treatment of femoral neck fractures. However, the DCLS is superior to the MCCS in Harris score, fracture healing time, femoral neck shortening, weight-bearing time and fracture healing rate. So, DCLS deserves further study.
Highlights
Femoral neck fractures are one of the problems in clinical treatment
Fracture healing rate of 92.9% (26/28) in the dynamic compression locking system (DCLS) group (Fig. 2) was significantly higher than that of 88.5% (23/26) in the multiple cannulated compression screws (MCCS) group (Fig. 3)
The operation time, length of incision, surgical blood loss, perioperative complications and incidence of bone healing complications were not statistically different between DCLS group and MCCS group, suggesting that the surgical incision in both groups was small with small trauma and less blood loss during the surgery, so both surgeries could be minimally invasive with less complications
Summary
Femoral neck fractures are one of the problems in clinical treatment. No internal fixation method is superior to other internal fixation methods in the treatment of femoral neck fractures. Femoral neck fractures are one of the most common fractures in the elderly and will reach 63 million by 2050, about half of which will occur in Asia, which seriously affects the quality of life of elderly patients [1]. For elderly patients with displaced femoral neck fractures (Garden III/IV), Less active individuals may receive a hemiarthroplasty, while more active individuals are treated with total hip arthroplasty [2]. The treatment of elderly non-displaced femoral neck fractures (Garden I/II) is still controversial [4]. Elderly patients with non-displaced femoral neck fractures tend to be surgically treated [5]
