What is Core Decompression?
Hip core decompression, also known as femoral head decompression or bone marrow stimulation, is a surgical procedure performed to relieve pain and preserve the health of the hip joint in certain conditions, particularly avascular necrosis (AVN) of the hip.
Here are some key points about hip core decompression :
Indications: Hip core decompression is commonly performed in cases of avascular necrosis, a condition in which the blood supply to the femoral head is compromised. AVN can result in the death of bone tissue, leading to pain, reduced range of motion, and eventual collapse of the femoral head.
Procedure: During hip core decompression, a small hole or channel is created in the femoral head using a drill or other specialized instruments. This hole is intended to relieve pressure within the bone and stimulate the formation of new blood vessels. It allows for the decompression of the area affected by avascular necrosis, potentially promoting healing and preventing further damage.
Timing: The timing of hip core decompression is important. It is often recommended in the early stages of avascular necrosis, before significant collapse of the femoral head has occurred. Early intervention aims to preserve the joint, reduce symptoms, and delay or avoid the need for more extensive surgeries such as total hip replacement.
Adjunctive Treatments: In some cases, hip core decompression may be combined with additional treatments to further support the healing process. These may include bone grafting, where healthy bone tissue is transplanted into the affected area, or the use of regenerative therapies such as stem cells or growth factors.
Rehabilitation: Following hip core decompression, a period of rehabilitation is typically required to optimize healing and restore hip function. This may involve physical therapy exercises, weight-bearing restrictions, and activity modifications. The specific rehabilitation plan will be tailored to the individual patient's needs and the stage of avascular necrosis.
Core decompression is often combined with bone grafting to help regenerate healthy bone and support cartilage at the hip joint. A bone graft is healthy bone tissue that is transplanted to an area of the body where it is needed.
When osteonecrosis of the hip is diagnosed early, core decompression is often successful in preventing collapse of the femoral head and the development of arthritis.
It's important to note that the success of hip core decompression depends on various factors, including the stage of avascular necrosis, the extent of involvement, the overall health of the patient, and individual response to treatment. Not all cases of avascular necrosis are suitable for hip core decompression, and other surgical options may be considered in more advanced stages. Consultation with best orthopedic surgeon or hip preservation specialist is necessary to evaluate your specific condition and determine the most appropriate treatment approach.
