Displaced femoral neck fractures in the elderly population are usually selected for arthroplasty to achieve better clinical function. In contrast, in younger patients, surgical preservation of the femoral head is preferred, and although there is now a uniform clinical consensus on the need to achieve anatomic repositioning and strong fixation in the treatment of femoral neck fractures, the timing of surgical treatment of femoral neck fractures is currently still more controversial. Gostas Papakostidis et al. recently conducted a search of the available literature and performed a pooled data analysis, which was published in Injury. The researchers conducted a comprehensive systematic search of existing medical databases and a total of seven eligible studies were included in the analysis. Based on existing medical strategies, the timing of surgical fixation of femoral neck fractures was divided into four groups: 1, fixation within 6 hours and after 6 hours of fracture; 2, fixation within 12 hours and after 12 hours of fracture; 3, fixation within 24 hours and after 24 hours of fracture; and 4, fixation within 6 hours of fracture and after 24 hours of fracture. After grouping the fractures post-injury and time of fixation, the cases were subgrouped according to the degree of fracture displacement, fracture fixation method, and quality of fracture reduction. The results of the study found that the current study did not show a significant difference between early or delayed internal fixation procedures in the treatment of femoral neck fractures. However, analysis based on the primary outcome indicator of fracture nonunion found that internal fixation after more than 24 hours for femoral neck fractures increased the rate of fracture nonunion. It is evident that internal fixation should be performed as early as possible after surgery for femoral neck fractures in young adults, and postoperative weight bearing should be as late as possible and observed with long-term follow-up.
