[Influence of proximal articular set angle on the result of surgical treatment for hallux valgus: an X-ray aspect].

Surgery correcting talipes varus and hallux valgus was conducted in 128 female patients (150 feet). The group of the patients was studied in accordance with the proximal articular set angle (PASA). The results of treatment were assessed, by taking into account this index; they were found to depend on the outcome of PASA correction. It has been concluded that the efficiency of surgery is determined only by the procedures used with regard to the individual anatomic features of each foot and the PASA calculated from preoperative X-ray films is one of the most important factors. Intraoperative normalization of this index with congruency recovery in the hallus metatarsophalangeal articulation yields long-term good results of treatment in most patients.
