In contrast to the management FNF in elderly patients, multiple cannulated screw fixation (CSF) is a widely accepted approach for the management of FNF in younger patients based on its easy operation, reduced tissue damage and preservation of original joints. Therapeutic strategies for FNFs include either arthroplasty or internal fixation depending on a number of factors, including patient age, fracture pattern and functional requirements. These poor outcomes result in high disability rates and health-care resource use, creating a serious socioeconomic burden. The neck of the femur has a complex blood supply and unique biomechanical characteristics, which can result in a series of complications such as nonunion and osteonecrosis of the femoral head (ONFH), a leading cause of pain and dysfunction. It has been estimated that the total number of hip fractures will increase to 6.3 million worldwide by 2050, with FNFs accounting for approximately 50% of the total number. FNFs are considered a serious injury due to the high-risk nature of surgical treatment, particularly in elderly patients with multiple comorbidities who are at higher risk of poor outcomes. Further evaluation with a more comprehensive study design, larger sample and long-term follow-up is needed.įemoral neck fractures (FNFs) are a common injury in both elderly patients as a result of low-energy trauma and younger patients as a result of high-energy trauma. This can influence the recovery of hip function, thereby impacting quality of life. ConclusionĬomminution is a risk factor for postoperative complications in young- and middle-aged patients with displaced and Pauwels type III FNF who undergo CSF. ResultsĬomminution was more likely to appear in displaced FNF patients (86.8%) compared with non-displaced FNF patients (8.9%), and the rate of comminution was closely associated with Pauwels classification (3.2% vs 53.5% vs 83.9%, P 0.05) between two groups at 1 year post-surgery. ![]() The incidence of postoperative complications, quality of life and functional outcomes was recorded at 1-year follow-up. Based on location of the cortical comminution, FNF patients were assigned to two groups: the comminution group (anterior comminution, posterior comminution, superior comminution, inferior comminution, multiple comminutions) or the without comminution group. Methodsįrom January 2019 to June 2020, a total of 473 patients aged 23–65 years with FNF treated by CSF were included in the present study. To investigate the distribution and influence of comminution in femoral neck fracture (FNF) patients after cannulated screw fixation (CSF).
