Introduction[edit | edit source]
Partial Hip Replacement/Hip hemiarthroplasty is an orthopaedic procedure for the treatment of certain femoral neck fractures where the femoral head is removed and replaced. "Hemi" refers to the fact that the prosthetic femoral head articulates with the original acetabulum.[1]
Hemiarthroplasty is desirable for the:
- Surgical treatment of subcapital neck fractures that are displaced and at high risk of femoral head avascular necrosis (Garden III and IV fractures).
- Co-morbid, less active, older patients (not good surgical candidates for THR) as long procedure with high morbidity in this group (younger or more active patients, THR has a better outcome).[1][2]
Technique[edit | edit source]
The femoral stem is inserted similar to that of a total hip arthroplasty and can be cemented or non-cemented. The acetabulum is not interfered with as it is still in good condition.[3][1] Most partial hip replacement surgeries can be performed in less than one hour in a hospital or surgical centre. The surgeon can choose to conduct open surgery, where a long incision is made diagonal to the joint, or a less-invasive computer-assisted procedure that requires only one or two small cuts. Computer-assisted surgery is usually preferred whenever the amount of bone that needs to be resurfaced or realigned is minimal[4].
Complications[edit | edit source]
- Infection
- Haematoma
- Non-union or malunion
- Implant failure
- Periprosthetic fracture
- Loosening
- Dislocation
- Osteolysis (in bipolar hemiarthroplasty)[1]
