The hip joint is a ball and socket type of joint which is formed between the thigh bone (femoral head) and the hip bone (acetabular socket). It is one of the strongest and firm fitted joints of the human body which could be inflamed or diseased due to certain joint ailments like Arthritis, Bursitis, Tendonitis and Fractures. Arthritis still stands as the prime indication for a hip replacement surgery.
A hip replacement surgery is a major surgical procedure where in a part or the complete hip joint is replaced by an artificial joint. The surgical procedure is performed under the influence of general anesthesia or spinal anesthesia, with or without sedation and requires a dedicated change in lifestyle and rehabilitative exercises to help aid in the artificial joint movement.
There are many different types of designs and materials are currently used in artificial hip joints. All of them consist of two basic components: the ball component (made of highly polished strong metal or ceramic material) and the socket component (a durable cup of plastic, ceramic or metal, which may have an outer metal shell).
The prosthetic components can be press-fit or cemented into place. This decision to only press fit or to cement the components is based on a number of factors, such as the quality and strength of your bone. A combination of the press-fit and cemented components can also be used.
The Birmingham Mid-Head Resection Arthroplasty is a novel bone-conserving procedure that, similar to hip resurfacing is used in younger, active patients.
This system is tailor-made for patients who are not suitable candidates for traditional total hip arthroplasty owing to their femoral head bone being of poor or weak quality. This poor-quality bone typically is seen in avascular necrosis (AVN) but also occurs in osteopenia (low bone mineral density), osteoporosis (pathologically low bone mineral density), or even when large femoral head cysts are present (seen in usage of long-term anti-inflammatory medication). A weak femoral head renders the bony anatomy unsuitable for hip resurfacing or arthroplasty. In these patients, a Birmingham Hip Resurfacing (BHR) or a Birmingham Mid-Head Resection (BMHR) prosthesis is recommended.
Hip replacement surgery has been performed since 4-5 decades and has relieved individuals from hip joint pain, restricted mobility, and discomfort.
