Dynamic-passive correction of hallux valgus and associated static foot deformities

Abstract

Purpose The paper presents, the effects of hallux valgus correction and coexisting static deformities of the foot (transversely-plano and plano-valgus foot) obtained with a new dynamic-passive method of treatment. Methods The study involved 50 patients; 26 with full big toe correction after the passive correction grip (group I) and 24 with big toe correction requiring additional passive abduction (group II). The patients regularly performed exercises using the designed device according to the planned schedule. The progress of the correction was assessed by a medical examination and additional tests. Results Results: The cross-sectional area [cm2] of the abductor hallucis muscle in three-time points among I and II groups of patients with the Hallux Valgus was measured based on MRI images. The STIR examination showed among other the abductor hallucis muscle edema after exercises with the DPc device were carried out. It evidences that exercises with the new device activate the muscle. Alignment of the big toes of both feet in groups I and II were obtained with a statistically significant result (p<0.05). The percentage progression of correction for HV and I/II IM was calculated. Conclusions Based on the new correction approach the alignment of the big toe phalanges and the remaining toes was obtained. The passive setup of the tendons with their distal inserts at the level of the big toe phalanges to the correct path of their course with the withdrawal of articular subluxations was obtained. Simultaneously, the big toe's passive correction was dynamically consolidated through a specially selected set of exercises.\
