Evaluating the efficacy of rehabilitation outcomes of the femoral neck system in treating femoral neck fractures: a two-year prospective study

Background Femoral neck fractures are prevalent among the elderly, and the femoral neck system (FNS), introduced in 2017, provides a minimally invasive treatment option with a dynamic bolt feature that enhances stability and facilitates early mobilization.

Methods This study involved 30 patients with femoral neck fractures treated with FNS at Dr. D. Y. Patil Medical College and Hospital from January 2021 to February 2023. The patients, aged 45-85 years, adhered to a structured rehabilitation protocol. Clinical outcomes were assessed using the Harris hip score (HHS) over 2-year follow-up period.

Results The cohort consisted of 30 patients (mean age: 65±10 years; 70% male). Fractures were classified as Pauwels I (30%), Pauwels II (40%), and Pauwels III (30%). At the final follow-up, 27 patients (90%) achieved union. The HHS improved significantly from a mean of 35±10 preoperatively to 85±15 postoperatively. Complications included one implant failure, one instance of limb shortening, and one case of avascular necrosis.

Conclusions The FNS is a safe and effective treatment for femoral neck fractures, promoting early weight-bearing and joint mobilization, leading to improved functional outcomes and reduced complications.
