Description

External fixator for fracture dislocation

Technical Field

The utility model relates to the field of orthopedic nursing devices, in particular to an external fixator for fracture dislocation.

Background

Fracture refers to a complete or partial fracture of the continuity of a bone structure. The disease is usually found in children and the elderly, and sometimes in young and middle-aged people. The patient is often a fracture at one part, and a few are multiple fractures. After timely and proper treatment, most patients can recover the original functions, and few patients can leave sequelae with different degrees. The fracture sometimes has several cases of dislocation, the first is fracture merging dislocation, which is one type of fracture, for example, humeral surgical neck folding and side-by-side joint dislocation, 1/3 fracture merging radius small head dislocation on ulna, distal radius fracture merging lower radioulnar dislocation, ankle fracture merging dislocation, and the like. Second, dislocation incorporates a fracture, such as a shoulder dislocation with a greater humeral tuberosity avulsion fracture, hip dislocation with an acetabular posterior superior rim fracture, and so forth. During treatment, the fracture and dislocation are required to be reset and fixed together. For patients with serious fracture, in the rehabilitation period, in order to accelerate the rehabilitation speed of the patients, the fracture wrapping part is usually required to be fixed so as to maintain the correct position after fracture reduction and prevent the patients from shifting in the activity; the existing fracture part fixing method is often carried out by adopting gypsum for external fixation, the gypsum fixing process is complicated, once the size of the fracture part is not adjustable after setting, the fracture part can be reduced after detumescence in the later period of patient recovery, and at the moment, the gypsum cannot be attached to the fracture part due to the non-adjustability of the gypsum, so that the healing of the later period of bones is affected.
