An anterolateral approach to the hip joint

Area of Science:

• Orthopedic Surgery
• Surgical Approaches
• Hip Joint Anatomy

Background:

• Traditional hip arthroplasty approaches can involve extensive soft tissue dissection and retraction.
• Potential risks include injury to surrounding neurovascular structures and impaired postoperative hip abductor function.

Purpose of the Study:

• To describe a novel anterolateral surgical approach to the hip joint.
• To evaluate the safety, efficacy, and functional outcomes of this approach for total hip arthroplasty.

Main Methods:

• Anterolateral approach utilizing the intermuscular plane between gluteus medius and tensor fascia lata.
• Partial stripping and controlled elevation of gluteus medius and gluteus minimus insertions for optimal exposure.
• Vastus lateralis muscle remained undisturbed to minimize dissection.

Main Results:

• The approach provided adequate anatomic orientation and exposure for total hip arthroplasty with minimal dissection and retraction.
• No injuries to the superior gluteal nerve or its branches were reported.
• In a review of 128 patients, hip abductor muscle strength was unimpaired, with no approach-related complications.

Conclusions:

• This anterolateral hip approach is a safe, effective, and technically straightforward method for primary total hip replacement.
• It facilitates excellent surgical exposure while preserving hip abductor function and minimizing the risk of nerve injury.
