Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] figure 1 Schematic diagram of the structure of the ulnar prosthesis provided by the embodiment of the present invention. Such as figure 1 As shown, the ulnar prosthesis includes the proximal ulna 30 and the distal ulna 10, the proximal ulna 30 and the distal ulna 10 are relatively movable, and the relative movement of the proximal ulna 30 and the distal ulna 10 is the ulnar prosthesis the length direction.

[0029] By setting the proximal ulna 30 and the distal ulna 10 of the ulnar prosthesis relatively movable, when the ulnar prosthesis is applied to younger patients, the proxim...

Abstract

The invention provides an ulna prosthesis, and relates to the technical field of bone prostheses capable of being implanted into a human body. The ulna prosthesis comprises an ulna near end and an ulna far end, wherein the ulna near end and the ulna far end are movably arranged relatively, and the relative movement directions of the ulna near end and the ulna far end are the length direction of the ulna. When the ulna prosthesis is applied to young patients, the ulna near end and the ulna far end can be relatively far away, so that the distance between the ulna prosthesis and connecting parts of the two ends of the radius can be enlarged, the length of the ulna prosthesis can be increased along with natural growth of the radius, and the elbow joint function and the wrist joint function cannot be affected.

Description

technical field [0001] The invention relates to the technical field of skeletal prostheses that can be implanted into the body, in particular, to an ulnar prosthesis. Background technique [0002] The pain in the early stage of ulnar tumors is mild and often intermittent. As the disease progresses, the pain gradually intensifies and develops from intermittent pain to persistent pain, which affects sleep. The tumor appears earlier, and the bone expansion and deformation can be touched. For example, if the bone tumor penetrates outside the bone, soft tissue masses of different sizes can be produced, and often form a larger mass in a short period of time; in the later stage of bone tumor, the function of the affected part is affected. Impairment, the rapid development of the disease, the more obvious symptoms of dysfunction, accompanied by muscle atrophy of the corresponding parts. Due to the consumption of tumors, the stimulation of toxins and painful torture, a series of sys...
