Purpose: We tried to understand the effects of the derotational closing wedge Akin osteotomy during the operation for the hallux valgus with pronation of great toe. Materials and Methods: Eighty five patients who had undergone Akin osteotomy among the eighty seven patients who had been treated with Scarf osteotomy with hallux valgus were included in this study. Derotational supination was added on the medial closing wedge Akin osteotomy at the base of proximal phalanx and it was secured with K-wire, headless screw or staple. We measured and analyzed pre- and post-operative hallux primus valgus angle and hallux pronational rotatory angle. Results: The hallux primus valgus angle improved an average of $14{\pm}2.98$ degrees to $-1{\pm}1.68$ degrees with the hallux pronational rotatory angle respectively from $24.8{\pm}7.64$ degrees to $4.7{\pm}4.22$ degrees. Conclusions: After the metatarsal osteotomy for the treatment of the hallux valgus with the pronation of great toe, derotational closing wedge Akin osteotomy can give us a belief that it can correct the hallux primus valgus angle and hallux pronational rotatory angle also and it can be a helpful method for minimizing the recurrence rate of the hallux valgus deformity.

Hallux valgus is a deformity characterized by lateral deviation of the great toe and medial deviation of the first metatarsal. When planning an operative treatment, it is important to realize that the deformity is tridimensional and diverse. Operative techniques include medial eminence resection, distal soft tissue procedure, first metatarsal osteotomy (distal, diaphyseal, proximal, or multiple), proximal phalanx osteotomy, arthrodesis (first metatarsophalangeal or metatarsocuneiform joint), and so on. Among these techniques, osteotomy is the main procedure for correcting the hallux valgus. The objective of this article is to describe the characteristics and recent advancements made for corrective osteotomies in the hallux valgus. The pathophysiology of the hallux valgus is also described.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.

Purpose: The purpose of this study was to evaluate the clinical and radiographic results of the parallel-shaped modified Scarf osteotomy which is performed the Scarf osteotomy parallel to the shaft of the 1st metatarsal bone for hallux valgus deformities. Materials and Methods: We retrospectively reviewed 43 patients who had been treated by the parallel-shaped modified Scarf osteotomy for hallux valgus deformities between January 2006 and March 2011. We evaluated the results after this Scarf osteotomy with respect American Orthopaedic Foot & Ankle Society (AOFAS) scores, radiologic results by comparing intermetatarsal angle between 1stand 2nd metatarsal bones and hallux valgus angle. Results: We checked out the pre-operational and post-operational radiologic evaluation of intermetatarsal angle and hallux valgus angle between 1st and 2nd metatarsal bones. The mean AOFAS scores improved from 63.5 to 88.5. At final follow up, The hallux valgus angle improved from $31.4^{\circ}$ (16-52) to $9.0^{\circ}$ (3-13) and the intermetatarsal angle improved from $18.6^{\circ}$ (12-30) to $9.3^{\circ}$ (6-12) postoperatively. There was no case of major complications included recurrence of valgus deformity, correction or fixation failure and stress fractures. Conclusion: Our results suggest the our parallel-shaped modified Scarf osteotomy produces improved AOFAS scores, and effective correction of hallux valgus deformities. Our Scarf technique of osteotomy which is performed in parallel to the metatarsal bone minimizes the need for skill while more reliable and obtaining good correction and avoids associated complications.

Purpose: This study analyzed the clinical and radiographic outcome of the severe hallux valgus corrected with proximal reverse chevron metatarsal osteotomy and Akin osteotomy. Materials and Methods: The study was based on 18 feet (15 patients) of severe hallux valgus (hallux valgus angle ${\geq}40^{\circ}$ or intermetatarsal angle ${\geq}18^{\circ}$) treated with proximal reverse chevron metatarsal osteotomy and followed for more than 1 year. Akin osteotmy was added in 72% of the patients. Clinically preoperative and postoperative AOFAS Hallux Metatarsophalangeal-interphalangeal score, VAS pain score and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, hallux valgus interphalangeal angle, the intermetatarsal angle and sesamoid position before and after the operation were analyzed. Results: AOFAS Hallux Metatarsophalangeal-interphalangeal score improved from 54.5 (25-78) to 87.7 (70-100) and VAS pain score decreased from 6.0 (3-8) to postoperative 1.2 (0-5). Ninety-six percents of the patients were satisfied with results. Radiologically hallux valgus angle was decreased from $43.3^{\circ}(31-58^{\circ})$ preoperatively to $6.8^{\circ}(-8-27^{\circ})$ postoperatively. The intermetatarsal angle was decreased from $18.4^{\circ}(11-24)^{\circ}$ preoperatively to $5.3^{\circ}(1-12^{\circ})$postoperatively. The sesamoid subluxation was improved from $2.8{\pm}0.4$ preoperatively to $0.4{\pm}0.6$ postoperatively. Conclusion: Proximal reverse chevron metatarsal osteotomy and lateral soft tissue release with additional Akin osteotomy is good treatment option for severe hallux valgus.

Authors studied 24 cases in 18 patients with the hallux valgus deformity treated by Reverdin osteotomy at Department of Orthopaedic Surgery, Wallace Memorial Baptist Hospital from January 1995 to December 1999. Reverdin osteotomy is one of the distal metatarsal osteotomies in the treatment of hallux valgus in adults. We performed Reverdin osteotomy on 24 cases (18 patients) for painful hallux valgus associated with an increased hallux valgus angle (> 35degrees) and first-second intermetatarsal angle(>13 degrees). The results were as follows. 1. The average first-second intermetatarsal angle was 16.8 degrees and average valgus angle was 37.3 degrees, preoperatively. they were corrected to 7.8 degrees and 12 degrees respectively. 2. The metatarsalgia of the great toe was subsided in all cases and they were satisfied with the result of their operations in respect to cosmetically and functionally. Avascular necrosis of capital fragment, nonunion, and dorsal angulation were not developed in any case. But one case had superficial wound infection and delayed union, presumably due to secondary infection.
