Summary
Anterior compression plates for hip arthrodesis showed a high failure rate, especially in patients with poor bone stock. This technique is not recommended due to significant risks of nonunion and fixation failure.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Hip arthrodesis is a surgical procedure to fuse the hip joint.
- Anterior compression plating aims to preserve abductor muscles for future total hip arthroplasty.
- Limited bone stock presents challenges in achieving stable hip fusion.
Purpose of the Study:
- To evaluate the long-term outcomes of hip arthrodesis using anterior compression plates.
- To assess the efficacy of this technique in preserving abductor musculature for subsequent procedures.
- To determine the union rates and fixation success in patients with compromised bone stock.
Main Methods:
- Retrospective evaluation of 16 patients who underwent hip arthrodesis with anterior compression plates.
- Average follow-up of 4.5 years.
- Analysis of union rates, nonunion, and fixation failure, particularly in primary and refusion cases.
Main Results:
- A high rate of nonunion was observed in primary fusions (45%).
- All patients undergoing refusion for failed arthrodesis experienced nonunion (100%).
- Inadequate fixation and predisposition to failure were noted in patients with limited bone stock.
Conclusions:
- Anterior compression plating alone is insufficient for hip arthrodesis in patients with limited bone stock.
- The technique is associated with a high risk of fixation failure and nonunion.
- This method may not adequately facilitate future conversion to total hip arthroplasty due to high failure rates.
