臀部重塑是全臀部置換術的新型替代選擇，為臀部疼痛但是不想放棄積極生活方式的患者提供了嶄新的選擇。

Birmingham臀部重塑系統是由Smith & Nephew公司(Memphis, TN, USA)的整型外科重建分部制造的，是一種光滑的鉻鈷球型套筒關節連接裝置，能夠保留患者自然骨骼結構和穩定性，全金屬移植物覆蓋關節表面，更象一個牙齒帽狀結構而不是一個臀部移植物。這就減少了術后脫臼和下肢長度不準確的危險，因為臀部重塑系統是全金屬移植物，因此比傳統使用金屬球和塑料槽狀結構的產品更加持久耐用。該產品已經獲得了美國食品藥品管理局的批準。

Hip Resurfacing Better for Active Patients
 
Hip resurfacing, a new alternative for total hip replacement, offers an innovative option for patients suffering from hip pain who do not want to give up their active lifestyle.

The Birmingham hip-resurfacing system, manufactured by the Orthopaedic Reconstruction Division of Smith & Nephew (Memphis, TN, USA) is a smooth chrome-cobalt ball-and-socket joint that preserves more of the patient's natural bone structures and stability, covering the joint's surfaces with an all-metal implant that more closely resembles a tooth cap than a hip implant. This approach reduces post-operative risks of dislocation and inaccurate leg length, and because the hip resurfacing system is an all-metal implant, it has the potential to last longer than traditional hip implants that use a metal ball and a plastic socket. The system has been approved by the U.S. Food and Drug Administration (FDA).
