Abstract

The invention provides a hand and foot bone defect implant which comprises a defect compensation body and two supporting bodies. The defect compensation body comprises a central rod and an outer sleeve fixedly arranged on the central rod in a sleeving mode. The two ends of the central rod can be inserted in medullary cavities of broken bone on the two sides respectively. The end faces of the two ends of the outer sleeve can be connected with fracture surfaces of the broken bone on the two sides respectively. Cavities used for containing filler are formed in the end faces of the two ends of the outer sleeve. At least one part of the surface of the cavity on each end face is attached to the surface of cortical bone of the corresponding connected broken bone so that the corresponding filler can make contact with the cortical bone. The two supporting bodies are connected with the ends of the central rod respectively. The supporting bodies can make contact with the inner walls of the medullary cavities to support the central rod when the two ends of the central rod are inserted in the medullary cavities of the broken bone. By means of the hand and foot bone defect implant, hand and foot bone defect injuries can be repaired, and therefore the original length of the broken bone can be kept, the risk of amputation is avoided, and part of functions can be kept.

Description

technical field [0001] The invention relates to an implant, in particular to an implant for hand and foot bone defects. Background technique [0002] Bone defects in the hands and feet are relatively common local bone injuries, and they are more common in people who are generally engaged in industrial construction and mechanical operations. Especially for the situation of knuckle defect, amputation is usually carried out, which will affect the integrity and beauty of the patient's hands and feet, and make the hands and feet lose their corresponding functions. In addition, the resulting hand and foot arthritis also plagues some patients, especially the hand joints are often mobile and easily affected, and the patients have bony hyperplasia nodules on the dorsal side of the distal fingertip joints. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain informa...
