Description

TECHNICAL FIELD

[0001] The utility model relates to fracture rehabilitation technical field more specifically, relate to a kind of positioning support for fracture rehabilitation. BACKGROUND

[0002] Positioning support for fracture rehabilitation is an auxiliary device used in the process of fracture treatment and rehabilitation, which can provide stable support and fixation for the fracture site, preventing the displacement of fracture ends again. This helps the correct healing of fractures and avoids the occurrence of malunion or nonunion, for example, for leg fractures, the positioning support can fix the arm in a specific position, limit the range of leg movement, and ensure that the fracture site remains stable during the healing process. After fracture, the injured site usually has pain, and the positioning support can reduce the movement and irritation of the fracture ends by fixing the fracture site, thereby reducing pain. It can help you maintain a relatively comfortable state during the rehabilitation process and improve the quality of life.

[0003] Chinese patent publication No. CN208319295U provides a multi-purpose calcaneal intramedullary minimally invasive stabilization system, which can treat various types of calcaneal fractures by providing positioning and guidance for the longitudinal headless compression screw of the calcaneus. For severe calcaneal Sanders IV fractures, one-stage subtalar joint fusion fixation can be performed, and when the subtalar fusion screw is flipped 180 degrees with the calcaneal intramedullary main nail, the internal fixation of the posterior superior tongue-shaped avulsion fracture block of the calcaneus can be performed. This can make the surgical operation precise and mechanized, greatly shorten the operation time and hospitalization time of patients, significantly reduce the risk of surgery, avoid the problem of difficult wound healing caused by the isolation of the skin by the steel plate after traditional steel plate surgery, and stabilize the internal fixation frame structure, which is beneficial to the early recovery of patients and reduces complications, with important social and economic benefits. However, for leg fractures, the knee rotation arc is not limited, and the fracture site may be subjected to excessive activity and stress, leading to unstable fracture ends and affecting the healing of fractures. Unstable fracture ends can hinder the formation and growth of callus, increasing the risk of nonunion or malunion, for example, in the case of femoral fractures, if the knee movement is not limited, the fracture site may be subjected to large shear force and torsional force during walking or movement, which can seriously affect the healing of fractures.
