Hip Bipolar Hemiarthroplasty for Femoral Neck Fracture
What is a bipolar hemiarthroplasty?
Treatment for femoral neck fractures can be successfully achieved through a bipolar hemiarthroplasty. Hemiarthroplasty is a surgical procedure that replaces one half of the hip joint with a prosthetic while leaving the other half intact. There are several different options available for the type of device to be used; we prefer to use a bipolar type, which has a femoral head that swivels during movement. This helps to reduce the amount of wear and tear on the new joint for longer-lasting results.
What is a hip fracture?
Hip fracture is a break that occurs near the hip in the upper part of the femur or thighbone. The extent of the break depends on the force that was involved. The thigh bone has two bony processes on the upper part – the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thighbone.
Fractures of the hip often occur within the femoral neck, a thin section of the thigh bone that helps to connect the “ball” end of the bone to the main shaft. When a fracture occurs in this area of the bone, it can cut off blood supply and lead to severe joint damage that cannot be treated with conservative methods.
Symptoms of A Hip Fracture
Immediately after a hip has fractured, the individual may find it difficult to stand and may experience the following symptoms:
- Severe pain in the hip and groin
- discomfort while rotating the hip
- Swelling and tenderness
- Inability to put any weight on the leg
- The leg may appear shortened
- Outward or inward turning of the foot and knee of the injured leg
What should I expect during my hip surgery?
During the hemiarthroplasty procedure, the damaged femoral head and neck are removed and replaced with the bipolar prosthetic. The prosthetic may be held in place with or without cement. Patients will need to undergo physical therapy after surgery to help restore movement and function to the joint. Therapy begins as soon as the patient feels comfortable after surgery, which is often the very next day. Most patients experience effective, long-term results from this procedure.
