Objective To explore a surgical therapy on close depressed fracture of the skull.Methods Ni-Ti form memory-alloy cramps were fixed on between the depressed bone and the normal surrounding skull in 16 patients with close depressed fracture of the skull.Results The follow up was 5～54 months(average 26 months).It indicated that there was no displacement and depressing of the fixed bone, no subcutaneous collection of fluid, no reject reaction and inflammation, and no erosion. The fixed bone and skull density showed normal by X ray and the fixed cramp did not disturb CT and MR scaning. All patients declared no mental burden and felt safe.Conclusion The Ni-Ti form memory-alloy cramp has a good mechanical restoration force and a good plastic effect,but no complication,it can increase the ability to resist external force in fracture region, and the surgical procedure is very simple, therefore it is ideal to treat the depressed fracture of skull.
