Description

First metatarsal dorsal osteotomy orthopedic plate

Technical Field

The utility model relates to the field of medical equipment, specifically a first metatarsal dorsal part osteotomy orthopedic plate.

Background

The first sequence of elevations or depressions is a common manifestation of ankle disease, usually with concomitant manifestations of certain diseases, such as hallux valgus, flat foot, high arch foot, etc., but may also occur alone. The change in the height of the first sequence may cause abnormal stress distribution in the foot, and may cause metastatic metatarsalgia or stress fracture in the long term.

The current surgical procedure that is clinically common for this type of disease is to lower or raise the first sequence by a distraction or closed osteotomy of the dorsal side of the first metatarsal, thereby restoring the normal state of the metatarsal foot. However, at present, the steel plate for fixing the first metatarsal osteotomy is rarely used clinically, most of the first metatarsal osteotomy is still fixed by a kirschner wire or a screw, but the strength of the screw fixation is insufficient, particularly for osteoporosis patients, the fixed position is easy to lose after the operation, the early functional exercise cannot be performed after the operation, the operation recovery time is long, and finally the operation is failed.
