Despite of reported and self experienced good results in favorable fitting preoperative anatomical conditions of some of these methods;it seems that no one is really satisfying under “difficult” or non favorable preoperative anatomic conditions. How could an optimum operation method for a satisfying correction of a mild to moderate hallux valgus look like? The well known criteria for an optimally satisfying method to achieve full normalization of important forefoot parameters under all conditions should be a lateralization, plantarization and derotation of the Ist metatarsal head and also a normalization of the distal metatarsal articular angle (DMAA) in combination with a soft tissue correction. Methods: In order to achieve this outcome without the disadvantages of shortening or the need for unloading, we developed a new operation technique and new fixation devices. We performed a simple transverse lazy-L subcapital osteotomy and after an additional soft tissue release the Ist metatarsal head was restored to its preplaned optimum position in terms of narrowing the IM angle, plantarization, correction of the hallux valgus angle, derotation of a pronation l malrotation and improvement of the DMAA. Fixation was achieved with an intramedullary angel-stable transfixed 30 mm titanium plate. The rigidity of the implant rendered interfragmental compression or solid bone contact unnecessary. The goal was only an optimal correction. All patients were allowed to ambulate with full weightbearing immediately after the operation. Results: We retrospectively reviewed 346 patients (433 feet) who underwent subcapital osteotomy between May 2007 and December 2011;308 were women and 38 men;their mean age was 65 years. The follow-up investigation was performed on average after 6.5 years (78 months);range 5.5 to 10 years (66 to 120 months). The AOFAS Score improved from 61.18 to 96.82 (t = 55.13, p ° to 4.21° (t = 89.70, p ° to 7.75° (t = 51.68, p ° to 6.61° (t = 29.34, p < 0.001). Minimal shortening of the first metatarsal (0.33 mm) and no recurrence of the deformity was observed. Conclusion: A new access to hallux valgus surgery is presented. Our results show that interfragmental compression between the osteotomy partners or good interfragmental contact is not necessary when a rigid intramedullary fixation device is used. The goal of this approach to hallux valgus surgery was to achieve excellent correction and a very rigid intramedullary angle-stable locked implant. The procedure yielded excellent results and was associated with no recurrence of hallux valgus.展开更多
