Partial Hip Replacement
The femoral head is replaced with a prosthesis while the natural socket is preserved — used primarily for selected hip fractures where early mobilisation and reliable pain relief are the priority.
What is Partial Hip Replacement?
Partial hip replacement — hemiarthroplasty — involves replacing the femoral head with an artificial prosthesis while leaving the natural acetabular socket undisturbed. It is most frequently performed for displaced intracapsular femoral neck fractures where the interrupted blood supply to the femoral head makes fixation unreliable. By replacing rather than repairing the head, the procedure eliminates the risks of avascular necrosis and non-union that accompany fixation attempts. Dr. Sai Kishan performs partial hip replacement at Lux Hospitals using contemporary unipolar and bipolar prostheses selected according to patient age and functional expectation.
How the Procedure Works
Anaesthesia & Approach Planning
Spinal or general anaesthesia; the most appropriate surgical approach — posterior or anterolateral — is selected based on patient factors.
Joint Exposure & Head Removal
The hip is opened; the fractured femoral head is carefully dislocated and removed; the acetabular surface is inspected and confirmed to be healthy.
Femoral Canal Preparation
The femoral canal is prepared with sequential broaches; trial sizing determines the correct stem dimensions and head offset.
Prosthesis Insertion & Reduction
The stem is inserted — cemented in the majority of elderly patients; the prosthetic head is attached and reduced into the native socket.
Stability Confirmation & Closure
Hip stability and limb length are assessed; the wound is closed in layers and physiotherapy with walking begins the following morning.
Outcomes
Who Needs This Treatment?
- →Rapid elimination of fracture pain with mobilisation beginning within 24 hours
- →Avoids the avascular necrosis and non-union risks of fracture fixation
- →The native acetabular socket is preserved — a simpler surgical reconstruction
- →Shorter operative time reduces anaesthetic exposure in medically frail patients
- →Bipolar prostheses reduce long-term socket wear compared to unipolar designs
- →Conversion to total hip replacement remains feasible if required in future
For displaced hip fractures in elderly patients, getting them mobile quickly is not just a surgical goal — it is a life-saving priority. Hemiarthroplasty achieves that reliably, safely, and consistently.
