RESUMO
INTRODUCTION: Hallux valgus is a frequent cause of pain, mainly in female population, characterized by deformity of the foot and important functional consequences. Open surgical techniques require relatively extensive incisions. Recently we see a tendency to use less invasive techniques with shorter hospitalization periods and better recovery. OBJECTIVE: To evaluate postsurgical clinical results in hallux valgus with minimally invasive surgery techniques according to the AOFAS scale. DESIGN: Longitudinal, prospective, descriptive and homodemic study. LOCATION: Hospital of Orthopedics and Traumatology, UMAE Puebla of the Mexican Institute of Social Security. MATERIAL AND METHODS: Twenty-nine patients with diagnosis of Hallux valgus treated between September 2004 and March 2008 were included. According to the AOFAS scale, we collected data from before the surgery, at one month and at 6 months postoperatively. We used univariate analysis of frequencies, measures of central tendency for demographic variables and the Wilcoxon test to evaluate pre and postoperative results with support from the SPSS version 12 program. RESULTS: The global evaluation of minimally invasive surgical technique according to AOFAS showed an average in the preoperative period of 60.37 (95% CI, between 53.87-66.38), at one month of 89 (95% CI, between 85.18-90.81) and at 6 months of 96.62 (95% CI, between 94.63-98.70). Mean age was 42 years (20-65), 22 women (75.86%) and 7 men (24.13%). We observed differences in the preoperative period, at one month and at 6 months with a p < 0.05 in global evaluation of AOFAS measurement scale for pain and function. DISCUSSION: Our results show that minimally invasive surgical technique is a good option for treatment of this pathology; they reveal the need to continue the study and to compare it with open surgical technique. Minimally invasive surgical technique, if properly done, reports good results and is an adequate therapeutic alternative for treatment of symptomatic hallux valgus.
