[Optimizing primary total hip replacement--a technique to effect saving of manpower].

Area of Science:

• Orthopedic Surgery
• Surgical Innovation
• Arthroplasty Techniques

Background:

• Total hip replacement (THR) is a common procedure.
• Traditional THR often requires multiple surgical assistants.
• Optimizing surgical efficiency and resource allocation in THR is an ongoing goal.

Purpose of the Study:

• To develop and evaluate a standardized surgical technique for total hip replacement.
• To assess the feasibility of reducing surgical manpower by employing a specialized retractor system.
• To determine if the new technique impacts operating time or complication rates.

Main Methods:

• A direct lateral approach was used with patients in a lateral position.
• A Bookwalter retractor system was employed to expose the acetabulum.
• Pelvitrochanteric muscles were partially detached using an omega-shaped incision.
• A case-control study compared the new technique with the traditional supine transgluteal approach.
• Operating time and number of assistants were primary outcome measures.

Main Results:

• The novel technique successfully performed total hip replacements with only one assistant.
• Operating times were comparable between the lateral position (112 min) and supine position (110 min).
• Complication rates were similar in both groups, including wound healing and transient ischalgia.

Conclusions:

• The described surgical technique for total hip replacement is effective in optimizing the procedure.
• This method allows for a reduction of one surgical assistant.
• The technique achieves efficiency gains without compromising patient safety or extending operative duration.
