A new shape memory clamp in small bone surgery.
A new internal fixative made form a titanium-nickel (TiNi) alloy having shape memory properties has been investigated and manufactured in cooperation between the Municipal Hospital Ostrava-Fifejdy, Department of Orthopaedic Surgery and the TU of Ostrava, Institute of Materials Engineering. The shape memory TiNi clamps with optimized parameters were designed after systematic study and development of required substructure. Experiments with animals supported the philosophy of the TiNi memory clamps application in small bone surgery. The conclusion drawn from preclinical, clinical, radiological and histological evidence from a total of 64 patients is that our new clamps proved to meet both contemporary theoretical demands and practical needs. Key words: shape memory alloy, small bone fragments osteosynthesis.
