Hip joint arthrodesis utilizing anterior compression plate fixation

W W Brien1, R J Golz, S H Kuschner

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.
