Summary
This study presents a simple articulated cement spacer technique for two-stage hip revision arthroplasty. The method improves hip function, allows partial weight-bearing, and prevents leg length discrepancy during the critical excision period.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- Infectious Disease Management
Context:
- Two-stage hip revision arthroplasty often results in poor hip function and significant leg length discrepancy.
- Managing infected total hip arthroplasty (THA) requires careful surgical planning, especially in immunocompromised patients.
Purpose:
- To describe a technique for creating a simple articulated cement spacer for use during the excision period of two-stage hip revision.
- To improve hip function, enable partial weight-bearing, and avoid leg length discrepancy between stages.
Summary:
- An antibiotic-impregnated cement spacer, reinforced with a tibial plate, was designed to mimic native hip anatomy.
- The spacer facilitated easier dissection, maintained leg length, preserved the joint space, and allowed early mobilization and partial weight-bearing.
Impact:
- This technique simplifies the second stage of revision arthroplasty, reduces complications, and offers potential economic benefits through shorter hospital stays and faster recovery.
- The method provides a viable solution for managing infected THA, particularly in complex patient populations.
