Hip hemiarthroplasty is a surgical technique employed to treat hip fractures. In this procedure, only one half (ball section) of the hip joint is substituted by a metal prosthesis.
The procedure is performed under regional or general anesthesia. An incision is made along the outer aspect of the affected hip. The surgeon gains access to the hip joint and the head of the femur is removed using surgical instruments and prepared to accept the prosthesis. The stem of the metal prosthesis is placed inside the femoral bone. The surgeon connects the metal ball that forms the new femoral head. The stem prosthesis can be press-fit in patients with a strong, healthy bone or cemented in cases of weak, osteoporotic bone. The method of implantation depends on the patient’s age and condition of the bone. At the end of the procedure, the incision is closed with absorbable sutures and skin glue and a dressing is applied.
- You will be prescribed medications to reduce pain and inflammation.
- Avoid lifting of heavy objects.
- Avoid standing for long hours.
- We may recommend physical therapy to strengthen the joint and the muscles and to help restore mobility to the hip joint.
Complications of hip hemiarthroplasty include infection, deep vein thrombosis, loosening of the prosthesis, and failure to relieve pain. Discuss with Dr. Fischer or his team if you have concerns regarding hip hemiarthroplasty surgery.
