臀部重塑是全臀部置換術(shù)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(tǒng)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(guān)節(jié)連接裝置，能夠保留患者自然骨骼結(jié)構(gòu)和穩(wěn)定性，全金屬移植物覆蓋關(guān)節(jié)表面，更象一個(gè)牙齒帽狀結(jié)構(gòu)而不是一個(gè)臀部移植物。這就減少了術(shù)后脫臼和下肢長(zhǎng)度不準(zhǔn)確的危險(xiǎn)，因?yàn)橥尾恐厮芟到y(tǒng)是全金屬移植物，因此比傳統(tǒng)使用金屬球和塑料槽狀結(jié)構(gòu)的產(chǎn)品更加持久耐用。該產(chǎn)品已經(jīng)獲得了美國(guó)食品藥品管理局的批準(zhǔn)。

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).
