Rehabilitation protector for external fixation of distal radius fracture

Abstract

The invention provides an external fixation rehabilitation protector for distal radius fracture, which can meet clinical requirements. The protector can meet the requirements of fixing an affected part of a patient and training at the initial rehabilitation stage. The problems that according to a traditional fixing mode, breathability is poor, the shape of a fixator does not adapt to the body surface of a patient, local pressure is too large, and the fixing posture is not easy to change are solved, wearing is convenient, and tightness can be adjusted according to the swelling condition of an affected part. The distal radius fracture fixing protector comprises a forearm module, a front and rear connecting module and a palm module. The forearm module and the palm module are completed through reverse modeling, and the front and back connecting module is connected with the forearm module and the palm module to form a protector body and can be connected with the forearm module to achieve locking in the palm flexion and back extension direction of the wrist and connected with the palm module to achieve locking in the radial deviation and ulnar deviation direction. And the rehabilitation requirements of patients with distal radius fractures are met.

Description

technical field [0001] The invention relates to the field of fracture fixation rehabilitation protective gear, in particular to an external fixation rehabilitation protective gear for distal radius fractures. technical background [0002] The ulna and radius are the two long bones of the human forearm. When the palm of the human body is forward, the radius is the side that is close to the body, and the ulna is the side that is far from the body. Ulnar deviation, radial deviation, palmar flexion, and dorsal extension are several common movements of the wrist joint. Ulnar deviation is the deviation of the wrist joint to the ulnar side, radial deviation is the deviation of the wrist joint to the radial side, and palmar flexion is the deviation of the wrist joint to the radial side. Volar rotation of the hand, dorsal extension is the rotation of the wrist joint toward the dorsal side of the hand. The above four movements can be combined to achieve wrist rotation. [0003] Dist...

AI Technical Summary

Problems solved by technology

[0006] To sum up, there are still some unreasonable designs in the existing related devices, such as: ulnar deviation, radial deviation, volar flexion, dorsiflexion, and dorsiflexion cannot be fixed at any angle, and free movement cannot be realized; Secondly, the adaptability of the forearm splint to the surface of the human body is not good, and it is easy to compress the muscles and affect the blood supply; Adjust the fixed posture according to the rehabilitation status; it cannot meet the needs of patients for proper exercise in the early stage of rehabilitation
