Partial Hip Replacement

Hip Hemiarthroplasty
(Partial Hip Replacement)
What is it?
Hemiarthroplasty is a surgical procedure where only the femoral head (ball of the hip joint) is replaced with a metal prosthesis, while the natural socket (acetabulum) is left intact.
When is it done?
Most commonly for fractures of the femoral neck (especially in elderly patients)
When the socket is healthy and not arthritic
Patient is less active or has lower functional demands
Procedure Highlights
The damaged femoral head is removed
A metal stem with a ball is inserted into the thigh bone (femur)
Socket is not replaced
Recovery
Patients typically start walking within 1–2 days after surgery
Shorter surgery time and less blood loss than total hip replacement
Rehabilitation focuses on regaining mobility and preventing complications like clots
