Nerve injuries associated with total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Neurology

Background:

• Nerve injury is a rare complication of total hip arthroplasty (THA), occurring in 0.6-3.7% of cases.
• Risk is elevated in patients with hip dysplasia or prior hip surgery.
• These injuries can lead to patient dissatisfaction and medico-legal issues.

Purpose of the Study:

• To comprehensively review nerve injuries associated with THA.
• To evaluate risk factors, etiology, diagnostics, management, prognosis, and prevention.
• To specifically analyze injuries to the sciatic, femoral, obturator, superior gluteal, and lateral femoral cutaneous nerves.

Main Methods:

• Literature review of nerve injuries in total hip arthroplasty.
• Analysis of risk factors, diagnostic modalities, and treatment strategies.
• Evaluation of prognostic indicators and preventative measures.

Main Results:

• Nerve injury incidence in THA is between 0.6% and 3.7%.
• Developmental hip dysplasia and prior hip surgery are significant risk factors.
• Specific nerves commonly affected include sciatic, femoral, obturator, superior gluteal, and lateral femoral cutaneous nerves.

Conclusions:

• Understanding risk factors and implementing preventative strategies are crucial for minimizing nerve injury after THA.
• Early diagnosis and appropriate management can improve patient outcomes.
• Further research into optimized surgical techniques may reduce nerve damage incidence.
