Trochanteric Fixation With a Third-Generation Cable-Plate System: An Independent Experience

Area of Science:

• Orthopedic surgery
• Biomaterials science
• Medical device engineering

Background:

• Greater trochanteric fractures post-total hip arthroplasty are severe complications impacting function.
• Fixation is challenging due to high forces and poor bone quality.
• Reoperation and nonunion rates are significant concerns.

Purpose of the Study:

• To evaluate reoperation and trochanteric nonunion rates.
• To assess a third-generation cable-plate system for fracture fixation.
• To analyze outcomes in patients undergoing hip arthroplasty.

Main Methods:

• Retrospective analysis of 35 patients with greater trochanteric fractures.
• Fixation using a third-generation cable-plate system.
• Indications included periprosthetic, primary, and revision arthroplasty.

Main Results:

• Union rate was 62.9%, with a nonunion rate of 31.4% at 2.5 years.
• Only 40% achieved perfect bone-on-bone reduction.
• 14.3% required reoperation for pain; 28.6% had wire breakage.

Conclusions:

• Trochanteric fracture fixation presents ongoing challenges with high reoperation rates.
• Poor bone quality and maintaining stable reduction are persistent difficulties.
• This complication after total hip arthroplasty requires further solutions.
