Summary

A hip replacement patient experienced an acrylic cement burn to the sciatic nerve. Surgical resection and grafting were successful, with nerve recovery observed 1 cm from the affected margin, suggesting a safe resection level.

Area of Science:

  • Orthopedic Surgery
  • Neuroscience
  • Biomaterials Science

Background:

  • Total hip replacement (THR) is a common orthopedic procedure.
  • Acrylic bone cement is widely used in THR for fixation.
  • Complications involving nerve damage, such as sciatic nerve injury, can occur during THR.

Observation:

  • A 63-year-old female patient developed an acrylic cement burn affecting the sciatic nerve after hip replacement surgery.
  • The extent of nerve damage was evaluated using electron microscopy.

Findings:

  • Surgical intervention involved resection of the damaged nerve segment and subsequent nerve grafting.
  • Electron microscopy revealed that the sciatic nerve tissue appeared nearly normal at a distance of 1 cm proximal to the cement margin.
  • This indicates that the nerve can recover or maintain normal function at this distance from the acrylic cement.

Implications:

  • The findings suggest that a resection margin of 1 cm from the acrylic cement may be a safe and effective level for managing sciatic nerve injury post-hip replacement.
  • This provides valuable guidance for surgical decision-making in similar cases.
  • Further research could explore the long-term outcomes and optimal management strategies for cement-induced nerve injuries.
