Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a special-shaped steel plate for correcting hallux valgus osteotomy.
Background
At present, due to the influence of heredity and bad life styles such as high-heeled shoes, more and more hallux valgus patients are younger and younger. The patient often becomes limp or even cannot walk due to the pain caused by hallux valgus deformity, and the life quality of the patient is seriously affected. The currently clinically most common surgical procedure is Chevron osteotomy, the first bone-extending distal osteotomy. This is also the most used treatment in hallux valgus patients.
After hallux valgus osteotomy, an artificial fracture is formed and needs to be fixed, and the micro steel plate is a better fixing method. However, at present, common metatarsal steel plates are used clinically, and are fixed at the positions after being plasticized. Because the steel plates are usually used for common fracture fixation and are fixed after fracture reduction and alignment are good, the steel plates are not suitable for the fixation of hallux valgus osteotomy correction, the loss of the fixed position is easy to cause and finally the operation fails. A first metatarsal distal osteotomy plate of the prior art patent No. CN105726110A includes a reverse S-shaped osteotomy plate main body, the osteotomy plate main body includes an integrally formed osteotomy plate proximal end, an osteotomy plate distal end, and a transition section for connecting the osteotomy plate proximal end and the osteotomy plate distal end, the osteotomy plate main body is provided with a plurality of fixing holes for fixing the osteotomy plate to the first metatarsal, the osteotomy plate proximal end and the osteotomy plate distal end are in the same direction as the first metatarsal for fixing the osteotomy plate to the first metatarsal, and the osteotomy plate proximal end and the osteotomy plate distal end are in the same direction as the first metatarsal. The existing steel plate has the following problems: 1. after hallux valgus osteotomy, the far end of the truncated first metatarsal bone is usually required to be displaced outwards and downwards to correct hallux valgus deformity, so that the corrected first metatarsal bone is not reset, but is in poor alignment, and is not suitable for a steel plate for common fracture fixation; 2. after osteotomy correction, dislocation exists between broken ends, common steel plates cannot be well attached, steel plate plasticity is often required in an operation of an operator, but satisfactory shapes are often difficult to achieve, so that the steel plates are poor in bone surface attachment, the first metatarsal bone soft tissue is thin and poor in attachment, soft tissue is difficult to suture or poor in suture, and serious complications such as steel plate exposure infection, osteomyelitis and the like are finally caused; 3. because usually the first metatarsal osteotomy point is located the distal end, therefore, the distal broken end is shorter after the osteotomy, and ordinary steel sheet often can only fix 1-2 screws, is difficult to fix stably, has the great risk screw to get into first metatarsophalangeal joint risk moreover, and insecure fixed like this neither can carry out the function exercise early, probably leads to the fixed inefficacy again to the risk of operation failure. Therefore, the special-shaped steel plate for correcting hallux valgus osteotomy is provided.
