Functional Outcome of Subtrochanteric Femoral Fractures Fixation by Proximal Femoral Locking Compression Plate

Area of Science:

• Orthopaedic surgery
• Traumatology
• Biomedical engineering

Background:

• Subtrochanteric femoral fractures present treatment challenges due to high stress and potential for implant failure.
• Traditional implants like intramedullary nails and extramedullary plates have limitations in this region.
• The proximal femoral locking compression plate (PF-LCP) has emerged as a promising alternative for managing these fractures.

Purpose of the Study:

• To evaluate the functional outcomes of subtrochanteric femoral fractures treated with the proximal femoral locking compression plate (PF-LCP).
• To assess the efficacy of PF-LCP in improving patient mobility, pain, and overall functional recovery.

Main Methods:

• A prospective study involving 25 adult patients with closed subtrochanteric fractures (excluding pathological or multiple injuries).
• Fractures were fixed using the proximal femoral locking compression plate (PF-LCP).
• Functional outcomes were assessed using the Modified Harris Hip Score (MHHS) after a minimum follow-up of 24 weeks.

Main Results:

• 88.0% of patients achieved satisfactory outcomes (excellent or good) by MHHS.
• Significant improvements were observed in weight-bearing, knee range of motion, pain reduction, and return to pre-injury activities.
• 72.0% of patients returned to their pre-injury state, with 76.0% experiencing no limb shortening.

Conclusions:

• The proximal femoral locking compression plate (PF-LCP) is a safe and effective implant for treating subtrochanteric femoral fractures.
• PF-LCP fixation leads to excellent functional recovery and patient satisfaction.
• This implant offers a reliable solution for the inherent instability and healing challenges associated with subtrochanteric fractures.
