Summary
Sciatic nerve palsy after total hip replacement is rare. This case highlights a rare complication of hematoma formation following direct anterior approach hip arthroplasty, successfully treated with prompt surgical evacuation.
Area of Science:
- Orthopedic Surgery
- Neuroscience
Background:
- Sciatic nerve injury is a rare complication of total hip replacement (THR), with reported incidence ranging from 0.09% to 3.7%.
- Common causes include nerve traction, hematoma compression, leg length discrepancy, malpositioned retractors, thermal injury, and cement extrusion.
- The direct anterior approach (DAA) is increasingly popular for THR, but specific complications related to this approach are still being documented.
