Published: May 2008

Background: The purpose of this study was to present the mid-term results of hallux valgus patients who underwent a modified chevron osteotomy.

Materials And Methods: Fifty-six patients (73 feet) with mild to moderate hallux valgus underwent a modified chevron osteotomy and Stoffella pin fixation between January 1999 and December 2004. Patients were evaluated clinically by the American Orthopedic Foot and Ankle Society (AOFAS) score. Pre- and postoperative radiographs were evaluated for the hallux valgus and intermetatarsal angles and sesamoid position.

Results: An improvement of 44.8 points in the AOFAS score was found. A change of 17.4 degrees in the hallux valgus angle and by 5.3 degrees in the intermetatarsal angle was achieved (p < 0.05). The change in the sesamoid position was significantly improved. Superficial skin infection in 3 cases, transient hypoesthesia in 2 cases, and bursitis due to screw irritation in 4 cases were the complications.

Conclusion: Stable and rigid fixation by modified chevron osteotomy using Stoffella pins allows early mobilization and weightbearing without a cast. We believe early mobilization of the joint provides better functional outcomes with fewer complications compared to other fixation techniques.

The purpose of this study was to evaluate the radiographic outcomes of distal chevron metatarsal osteotomy associated with lateral joint capsule split as only lateral soft tissue release in patients with symptomatic moderate and severe hallux valgus (HV) deformity. Ninety patients (103 feet) at our institution between January 2014 and December 2019 were included in the present retrospective study. Each patient was evaluated preoperatively and at final follow-up by means of weight bearing radiographs lateral and dorsoplantar views.

Objective: To probe the influence of early rehabilitation nursing on postoperative rehabilitation of patients with hallux valgus on the basis of information-motivation-behavior skills (IMB) model.

Methods: Convenience sampling was adopted, and 80 patients with hallux valgus admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University from July 2020 to July 2022 were randomly separated into control group (CG) and observation group (OG) with 40 patients in each group according to the time of admission. Patients in the CG received routine nursing and rehabilitation guidance and follow-up.

First metatarsophalangeal joint (MTPJ) fusion an effective surgical intervention for conditions such as hallux valgus and hallux rigidus. This systematic review and meta-analysis aims to compare safety and efficacy of crossed screws versus plating supplemented with an interfragmentary screw. A literature search of the Scopus, Embase, Web of Science, and MEDLINE databases was performed to identify all studies directly comparing the two techniques.

Hallux valgus (HV) is the most common foot deformity. It has various pathogenic factors that make its pathogenesis challenging to understand. As the disease progresses, patients experience amplified pain and decreased activities, significantly affecting their quality of life.

Background: Hallux valgus (HV) is a complex, multiplanar deformity. In this study, we examined the interrelationships between various components of this deformity using weightbearing computed tomography (WBCT). We hypothesized that the severity of traditional axial plane deformities would correlate with malpositioning of the metatarsosesamoid complex, first-ray coronal rotational deformity, and malalignment of the hindfoot and midfoot.
