Summary

The anterolateral abductor split approach for total hip arthroplasty shows a low dislocation rate (<1%). This surgical technique is effective in minimizing postoperative dislocation, especially for high-risk patients.

Area of Science:

  • Orthopedic Surgery
  • Arthroplasty Research

Background:

  • Total hip arthroplasty (THA) utilizes transtrochanteric, posterior, and anterolateral surgical approaches.
  • Complications include dislocation, nonunion, heterotopic ossification, neurovascular damage, limp, and malalignment.

Purpose of the Study:

  • To evaluate the efficacy of the anterolateral abductor split approach in primary total hip arthroplasty.
  • To assess the postoperative dislocation rate associated with this specific surgical technique.

Main Methods:

  • Retrospective review of a consecutive series of 1518 primary total hip arthroplasty cases.
  • Analysis of dislocation rates stratified by preoperative diagnosis.

Main Results:

  • An overall dislocation rate of 0.79% (12 of 1518 cases) was reported.

  • Patients with prior trauma or congenital hip dysplasia faced the highest dislocation risk.

    • Conclusions:

    • The anterolateral abductor split approach offers excellent hip joint visualization and neurovascular protection.
    • This approach can significantly minimize postoperative dislocation rates in primary THA, even in high-risk patient groups.
