Full text available on request.Abstract
Neck of femur fractures (NOFs) are increasingly relevant due to the aging population. Postoperative complications are frequent in cannulated screws (CS), a common surgical treatment option. Recently, the femoral neck system (FNS) was introduced alternatively, to limit postoperative complications. However, literature regarding its postoperative radiological outcomes is scarce. This study aimed to compare the FNS and CS on radiological outcomes (primary outcome), operation time, complications and reoperation details and rate in geriatric patients (age ³65 years) with NOFs. A retrospective age/gender matched cohort was analyzed, where loss of femoral offset (FO) and hip length, important parameters for implant stability, were measured in postoperative X-rays at different time points. Additionally, we collected patient characteristics, operation time, complication data, and reoperation details and rates from patient files. We included 82 FNS-patients and 85 CS-patients with similar patient characteristics. No significant differences were found in FO and loss of hip length between the FNS- and CS-group at 6-weeks (p=0.775 & p=0.962) and ³6-months postoperatively (p=0.601 & p=0.058). Difference in complication rate was non-significant (2.4% vs 9.6%, p=0.220). However, reoperation rate was significantly higher in the CS-group (0.0% vs 9.6%, p=0.017) and operation time was higher in the FNS-group, 49 vs 45 minutes (p=0.007). This study suggests the FNS is a promising alternative to the current treatment options for NOFs in the geriatric population. The proposal for future studies entails a prospective design with larger sample size and standardised X-ray protocol and incorporating postoperative function as an outcome measure.
