Mini-incision dynamic condylar screw fixation for comminuted subtrochanteric hip fractures

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomedical Engineering

Background:

• Comminuted subtrochanteric femoral fractures present complex treatment challenges.
• Minimally invasive techniques aim to reduce surgical trauma and improve outcomes.

Purpose of the Study:

• To evaluate the efficacy of indirect reduction and mini-incision dynamic condylar screw (DCS) fixation for comminuted subtrochanteric femoral fractures.

Main Methods:

• A cohort of 43 patients (29 male, 14 female) with comminuted subtrochanteric femoral fractures underwent indirect reduction and mini-incision DCS fixation.
• Fractures were classified using AO and Seinsheimer systems.
• Functional outcomes were assessed with Harris hip and Merle d'Aubigne scores.

Main Results:

• Mean time to full weight bearing was 11 weeks, and mean time to union was 16 weeks.
• No non-union or implant failure occurred in the mean 25-month follow-up.
• Excellent or good functional results were achieved in all patients, with a mean Harris hip score of 88.

Conclusions:

• Indirect reduction and mini-incision DCS fixation yield favorable results for comminuted subtrochanteric femoral fractures.
• Meticulous surgical planning and execution are crucial for optimal outcomes.
• Preservation of vascularity promotes rapid healing and prevents complications like non-union and implant failure.
