Background

Metatarsal fractures are one of the most common fractures of the foot, accounting for 35% of all foot fractures, with about 70% involving the fifth metatarsal, and about 80% occurring in the basal portion in the case of fifth metatarsal fractures. The fifth proximal metatarsal plays a very important role in maintaining stability of the lateral arch. Fifth metatarsal basal fracture, also called "JONES fracture", is preferably caused by fatigue, especially after long distance marching or running, and is mainly manifested as pain, swelling and other discomfort of joints, and serious patients may have deformity. However, when the foot is subjected to plantarflexion and inversion violence, the lateral collateral ligaments of the ankle joint may be involved at the same time, the ankle ligaments are damaged, the lateral collateral ligaments of the ankle joint of the patient are chronically unstable, the foot is repeatedly twisted during load walking, and traumatic arthritis is caused, so that the quality of life is seriously affected.

Currently, the most common treatment methods are traditional plaster fixation, surgical intervention, and brace fixation, and the like, and the prior art has a number of disadvantages, such as:
