Articular interposition of broken trochanteric wires
1Makassed General Hospital, Beirut, Lebanon.
Summary
Recurrent dislocation after total hip arthroplasty can occur due to broken trochanteric wires migrating into the joint. Revision surgery successfully resolved this rare complication, highlighting the need for careful consideration during trochanteric osteotomy.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Arthroplasty research
Background:
- Total hip arthroplasty (THA) is a common procedure to address hip joint degeneration.
- Trochanteric osteotomy is sometimes performed during THA to improve exposure and facilitate component placement.
- Complications, though rare, can impact patient outcomes and prosthetic longevity.
Observation:
- A case presented with recurrent dislocations following THA.
- Intra-articular migration of broken trochanteric wires was identified as the cause.
- These wires were interposed between the articulating surfaces of the prosthetic components.
Findings:
- The patient underwent revision total hip arthroplasty to address the complication.
- The revision surgery resulted in a good clinical outcome.
- This specific complication, wire migration and interposition, is unusual but significant.
Implications:
- Surgeons performing trochanteric osteotomy in THA must be aware of this potential complication.
- Careful technique and post-operative monitoring are crucial to prevent wire migration.
- Understanding rare complications aids in improving surgical safety and patient outcomes in hip replacement surgery.
