Norian SRS Cement             One of the age old problems for orthopaedic surgeons and their patients with fractures of the wrist is weakness in the bone substance of the wrist with subsequent collapse, in part, of the wrist bone structure, causing a shortened appearance of the wrist and a deformity which is sometimes significant. This can occur even after a very adequate closed reduction or setting of the fracture and placement in a cast.     To address this problem and hopefully prevent it, an injectable, moldable calcium phosphate cement has been developed to be injected into the wrist in patients who may develop this complication, thereby strengthening the wrist and avoiding collapse of the bone. It conforms to the shape of the void in which it is injected.     Norian SRS cement uniquely mimics the chemical composition in crystallographic structure of the mineral phase of bone. The high compressive strength of this material as well as its gradual replacement by bone supports its potential use in fractures such as certain wrist fractures. Norian cement allows normal fracture healing, resorbs via normal cellular remodeling, and maintains strength during remodeling.     Norian SRS cement is expected to be available for use in the United States in the near future.
