Summary
Severe vascular injury during total hip replacement (THR) is rare but life-threatening. Understanding injury mechanisms aids early diagnosis and treatment of these critical vascular complications.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Medical Device Safety
Background:
- Total hip replacement (THR) is a common orthopedic procedure.
- Severe vascular injury is a rare but serious complication of THR.
- Vascular damage can threaten limb viability and patient life.
Observation:
- Vascular injuries occurred in 3 out of 721 THR cases (0.25% incidence).
- Affected vessels included the external iliac artery/vein and femoral artery/vein.
- Injuries resulted from bone cement, pneumatic drilling, and scar tissue resection.
Findings:
- Specific mechanisms identified: sharp bone cement, pneumatic drill use, and surgical resection.
- External iliac vessels, femoral artery, and femoral vein were implicated.
- Three distinct cases illustrate varied injury mechanisms during THR.
Implications:
- Early recognition of vascular injury mechanisms is crucial for THR surgeons.
- Improved understanding can lead to timely diagnosis and intervention.
- Minimizing vascular complications enhances patient safety during THR procedures.
