A vastus lateralis (VL) muscle flap effectively treats complications after total hip arthroplasty (THA), preventing hip disarticulation (HD) in most patients. This muscle flap offers a promising solution for complex THA cases.
Area of Science:
- Orthopedic surgery
- Musculoskeletal reconstruction
Background:
- Chronic infections and soft-tissue defects are severe complications following total hip arthroplasty (THA).
- Hip disarticulation (HD) is a high-risk procedure with poor outcomes for these complications.
- The use of vastus lateralis (VL) muscle flaps for preventing HD after THA is unexplored.
Purpose of the Study:
- To evaluate the efficacy of an ipsilateral, pedicled vastus lateralis (VL) muscle flap in preventing hip disarticulation (HD) in patients with recurrent complications after total hip arthroplasty (THA).
Main Methods:
- Retrospective case review of 14 patients undergoing soft-tissue hip reconstruction with a VL muscle flap.
- Analysis of 6-month postoperative outcomes.
Main Results:
- 86% of patients achieved full recovery at 6 months, with preserved hip range of motion, no pain, and no ambulation weakness.
- Two patients (14%) ultimately required hip disarticulation despite VL flap intervention.
Conclusions:
- A VL muscle flap is an effective treatment for nonhealing THA complications and a prophylactic measure for patients at high risk of HD.
- The VL muscle's size, local anatomy, and vascularity make it ideal for reducing dead space and promoting healing.
- Further prospective studies are needed to define the optimal patient population for this technique.
