What are the indications for total hip arthroplasty?
The goal of hip arthroplasty is to relieve pain, correct deformity, and restore range of motion (ROM) and function. Indications include severe degenerative changes and failure of nonoperative treatment for 3–6 months. Occasionally, THA is chosen when a fracture of the femoral head or neck cannot be repaired or repair has little chance for clinical success (e.g., an 80-year-old with a severely displaced femoral neck fracture). 37. What is metal on metal hip resurfacing? Hip resurfacing is a surgical alternative to conventional hip arthroplasty. The femoral head is reshaped to accept a metal cap with a small guide stem. The head size is about 50 millimeters in diameter and a metal cup is set into the acetabulum. 38. Are there any advantages with the use of metal on metal resurfacing devices? • Femoral head is preserved. • Femoral canal is preserved and no associated femoral bone loss with future revision. • Larger size of implant “ball” reduces the risk of dislocation significantly. • St
