Distal radius fracture alignment and stabilization can be a surgical challenge in the face of severe comminution and bone loss. We describe a technique using a calcium phosphate/sulfate bone cement, as an adjunct to internal fixation. This bone cement is biocompatible, osteoconductive, and sets quickly with an isothermic reaction. The use of bone cement eliminates the need for primary autologous bone grafting and allows for easier reduction and retention of reduction at the time of surgery. Bone cement is employed for the following purposes in comminuted fractures: (1) to fill a void due to lost or crushed cancellous bone, (2) to hold larger unstable fragments while hardware is placed, and (3) to retain fragments too small to take hardware. Available bone cements, studies involving the use of bone cement for distal radius fractures, indications, and surgical technique will be reviewed.
面对严重粉碎性骨折和骨缺损时,桡骨远端骨折的复位和固定可能是一项外科挑战。我们描述了一种使用磷酸钙/硫酸钙骨水泥作为内固定辅助手段的技术。这种骨水泥具有生物相容性、骨传导性,并且通过等温反应快速凝固。骨水泥的使用消除了一期自体骨移植的必要性,并使手术时更容易进行复位和维持复位。骨水泥在粉碎性骨折中用于以下目的:(1)填充因松质骨丢失或粉碎而形成的空隙,(2)在放置内固定器械时固定较大的不稳定骨折块,(3)固定太小而无法放置内固定器械的骨折块。本文将对现有的骨水泥、涉及使用骨水泥治疗桡骨远端骨折的研究、适应证和手术技术进行综述。
