|October 1, 1980
Summary
The direct anterior approach offers effective exposure for total hip arthroplasty, providing excellent acetabular visualization. This method minimizes complications and reduces patient morbidity.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Surgical Approaches
Background:
- Total hip arthroplasty (THA) is a common procedure for hip joint conditions.
- Surgical approach selection impacts outcomes and patient recovery.
- The direct anterior approach (DAA) is an alternative to traditional methods.
Purpose of the Study:
- To evaluate the efficacy and safety of the direct anterior approach for primary total hip arthroplasty.
- To assess the visualization, operative parameters, and patient outcomes associated with the DAA.
Main Methods:
- A curved transverse skin incision and longitudinal splitting of the tensor fascia lata.
- Use of modified femoral rasps with the leg in external rotation.
- Prospective analysis of 104 primary THA procedures in 85 patients over three years.
Main Results:
- Excellent acetabular visualization was achieved.
- Trochanteric osteotomy was rarely required (3%).
- Average operative time was 65 minutes, with moderate blood replacement (1.9-3.5 units).
- Mean postoperative stay was 12.8 days (unilateral) and 22.3 days (bilateral).
- Low perioperative complication rate (4 patients).
Conclusions:
- The direct anterior approach is a safe and effective surgical option for primary total hip arthroplasty.
- It provides excellent visualization and leads to limited patient morbidity.
- The DAA facilitates efficient primary THA with favorable outcomes.
