Birmingham Hip Resurfacing, commonly known as BHR surgery, is a specialized orthopedic joint preservation procedure used to treat advanced hip arthritis, osteoarthritis, avascular necrosis, and certain degenerative hip conditions. During the operation, the damaged cartilage and bone surfaces of the femoral head are carefully reshaped and covered with a smooth metal cap while the hip socket receives a matching metal component. Unlike conventional hip replacement surgery that removes a large portion of the femur, hip resurfacing conserves more healthy bone tissue and maintains closer to natural hip biomechanics. This approach can offer improved stability, lower risk of dislocation, and better performance during high activity levels for selected patients. The procedure is commonly recommended for younger and physically active individuals with strong bone quality who wish to maintain mobility and delay future revision surgeries. Advances in implant technology, surgical planning, and rehabilitation protocols have significantly improved recovery outcomes and long term functional performance following Birmingham Hip Resurfacing surgery.
