What Is Hemi (Partial) Hip Replacement?

Hemiarthroplasty (Partial Hip Replacement)—also known as hip hemi-replacement—is a surgical procedure where only the femoral head (the “ball” part of the hip joint) is replaced, while the acetabulum (the “socket”) is left intact.

What Is Hemi (Partial) Hip Replacement?

Hemiarthroplasty is typically performed in patients who:

  • Have suffered a fracture of the femoral neck (commonly due to osteoporosis or trauma).
  • Are elderly or less active, where full joint replacement may not be necessary.
  • Do not have arthritis or damage in the hip socket.

Types of Hemi Hip Replacement

  1. Unipolar Hemiarthroplasty
    • The femoral head is replaced with a single piece that articulates directly with the natural socket.
  2. Bipolar Hemiarthroplasty
    • The implant has two articulating components (femoral head within a shell), which reduces wear on the socket and improves motion.

Summary

  • Ideal for: Hip fractures without socket damage.
  • Surgery Time: ~1.5 to 2 hours.
  • Benefits: Shorter operation, faster recovery, less invasive than total replacement.
  • Drawbacks: May wear faster than total hip replacement if socket becomes arthritic.
