A Partial Functional Restoration After Hallux Valgus Correct Surgery - A Controlled Preliminary Study

Introduction: Hallux valgus is the most common condition found in the foot, caused by a progressive failure of the first ray stabilization means. The hallux is deviated into valgus, the first metatarsal into varus, and their association leads to a subluxation of the metatarsophalangeal joint of the first ray. Surgery is a treatment frequently used to correct this condition. So, is the static postural balance altered after corrective surgery? Materials and Method: 23 subjects participated in the study, all women, divided into two groups: control and hallux valgus. The hallux valgus group was evaluated three months post-operatively. Bipodal tests were carried out on a stabilometry platform, one with eyes open and one with eyes closed. The pressure center parameters were recorded and analyzed, such as the length or the area of the pressure center. Results: The results obtained showed significant differences between the two groups and were statistically significant, with a p-value of 0,05. The pressure center values are higher in the hallux valgus group. Conclusion: Some results found in the literature agree with the results of the present study. There are significant deficits in the static postural balance three months after corrective surgery. Other studies with a larger sample may be performed to confirm or not the results of this study.

Does Hallux Valgus Surgery Modify The Gait Parameters? Literature Review

Background: the deformation of the hallux into a valgus constitutes the most frequent deformation of the forefoot and one of the most performed corrective surgeries in the region. This deformation is the cause of many biomechanical disorders and causes gait disturbances. This review aims to analyze the restoration of space-time and kinematic parameters of walking in the aftermath of corrective surgery for hallux valgus. Methods: four studies were analyzed according to the main criteria of walking speed, support time, step length and kinematics of the ankle and foot before and after the intervention. Results: If some of the results obtained in the analyzed works show an improvement of these criteria in post-operative, the subjects having benefited from hallux valgus surgery seem to present some persistent issues in the spatiotemporal and kinematic parameters. Conclusion: This work does not demonstrate the superiority of one surgical technique over another in the recovery of gait. This recovery does not seem absolute, but this review highlights above all the lack of literature on this subject.
