OPEN WEDGE OSTEOTOMY DEVICE FOR CORRECTION OF HALLUX VALGUS

摘要

The present invention relates to an open-type wedge osteotomy device for correction of hallux valgus. The open wedge osteotomy device for correction of hallux valgus comprises: a first fixing device fixedly coupled to a proximal portion of the first metatarsal bone to be able to rotate along with a distal portion of the first metatarsal bone, and including a rotation portion with a fastening hole at the center and a first guide portion extending from the rotation portion to cross the first metatarsal bone; a second fixing device fixedly coupled to the proximal portion of the first metatarsal bone and the inner cuneiform bone, and including a fixing ring portion with a ring hole formed at the center, wherein the rotation portion of the first fixing device is inserted into the ring hole to be able to rotate, and a second guide portion extending in parallel with the first guide portion; and a fastening device fastened to the fastening hole of the rotation portion while the rotation portion is inserted into the ring hole of the fixing ring portion and the first guide portion and the second guide portion extend to cross the first metatarsal bone, and including a through-hole formed at the center, a head portion, and a fastening portion formed by a predetermined length on a lower portion of the head portion and having a thread formed on an surface thereof such that the fastening portion is fastened to the fastening hole, Incision guides are formed on the rotation portion and the fixing ring portion to guide a saw for osteotomy along the first guide portion and the second guide portion facing each other, such that the saw for osteotomy cuts between the distal and proximal portions of the first metatarsal bone.
