Surgical correction of the first ray deformity using osteotomy biomechanical modeling

Summary:

Objective: to enhance the outcomes of the first ray surgical correction using osteotomy biomechanical modeling of the first metatarsal bone. It allows obtaining quantitative data for the «bone — fixator» system stability as additional criteria for selecting surgery methods and surgery therapeutic approaches. Material and Methods. 97 female patients underwent surgical corrections of static deformities in the anterior parts of the feet. Biomechanical modeling of osteotomies for the first metatarsal bone was used for the main group (50 patients) at the stage of pre-surgery planning. Results. Radiological results showed no significant differences between the groups of patients. The integrated ACFAS index in post- surgery period was statistically significant inpatients of the main group. The detection rate of the restriction of movements, pain syndrome and edema around the first metatarsal bone was higher in the control group. Conclusion. The identified differences in the dynamics of functional and restorative processes proved the efficiency of objective estimation and obtaining stability in «bone — fixator» system. Biomechanical modeling is an efficient tool of the decision making support system for surgical correction of the first ray deformities.
