Post-operative neuropathy after total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Neurology

Background:

• Nerve palsy is a distressing complication following total hip arthroplasty (THA), impacting patient rehabilitation and mobility.
• Potential causes include surgical manipulation, retractor placement, limb lengthening, and post-operative hematoma.
• Literature suggests associations with hip dysplasia, leg lengthening, uncemented femoral components, and female gender.

Purpose of the Study:

• To determine the incidence of nerve palsy after primary THA at a high-volume tertiary care center.
• To identify specific risk factors associated with nerve palsy in this patient population.

Main Methods:

• Retrospective analysis of 39,056 primary total hip arthroplasties.
• Statistical examination to identify correlations between patient demographics, pre-existing conditions, and nerve palsy occurrence.

Main Results:

• The overall incidence of nerve palsy was 0.3%.
• Identified risk factors included spinal stenosis or lumbar disc disease, age younger than 50, and smoking.
• No association was found with hip dysplasia, leg lengthening, uncemented components, or female gender in this cohort.

Conclusions:

• Nerve palsy following THA is infrequent, with specific risk factors identified at this institution.
• Early diagnosis with imaging and potential hematoma evacuation are crucial.
• Supportive care, including bracing and therapy, is essential for managing nerve palsy recovery.
