• Partial Hip Replacement Surgeon in New York City


    Your hip is essentially a ball-and-socket type of joint, with the head of the leg bone (femur) fitting into a part of your pelvis called the acetabulum. While a total hip replacement involves replacement of the femur’s head and the acetabulum’s surface, a partial hip replacement is replacement of the femur’s head only. This leaves the natural tissues composing the pelvis intact. Also called a hemiarthroplasty, a partial hip replacement is almost always indicated following a traumatic hip injury, such a fractured or broken hip. However, your partial hip replacement surgeon in NYC will typically not recommend this kind of hip replacement procedure if you suffer from degenerative arthritis of the hip joint.

     

    Hip Injuries Indicating Partial Hip Replacement Surgery


    A piece of tough, connective tissue surrounding the edge of the hip socket, the labrum assists in securing the hip joint and preventing fluid from leaking out of the joint. When this important seal is damaged, the hip suffers changes in hip rotation and general debilitation. As a result of being off-center, the hip joint receives excessive impact and weight from physical activities, creating a series of consistent injuries to the joint and labrum. The accumulation of these frays and tears to the labrum generates stiffness, pain or pinching sensations in that area.

    The reason your partial hip replacement surgeon in Staten Island cannot perform this surgery on hips damaged by bone disease is because an arthritic femoral head and acetabulum is too unstable to support only a partial hip replacement. Although the femoral neck may be fractured and the ball must be repaired and/or replaced, the hip joint socket remains strong enough for a partial hip implant.

    Grades of Fractures in Hip Joint Injuries


    Grades one, two and three (subtrochanteric, intertrochanteric and fractured neck) will not interfere with the hip joint and can usually be repaired with nailing devices or pins. A grade four fracture (subcapital fracture) is further sub-graded into four other fracture types, according to the severity of displacement occurring at the fracture site.

    • Type 1 — A stable fracture with impaction (bones remain pressed together)
    • Type 2 — A complete, non-displaced fracture (bones stay aligned)
    • Type 3 — A displaced fracture (with two contacting bone fragments)
    • Type 4 — A completely displaced fracture (no contact between fractured bone fragments)

    If your partial hip joint surgeon in Jersey City diagnoses a type four fracture, this means there is disruption of blood flow to the femoral head that could lead to bone death. Since this type of fracture is unlikely to heal using pins, a partial hip replacement is recommended to prevent a potential total hip replacement in the future. If you have not been diagnosed with a degenerative hip disease like osteoarthritis, you may be eligible for a partial hip replacement.
