Background: Hallux valgus (HV) deformity is a common, potentially debilitating deformity. And evidence with high-quality for the conservative treatments of HV deformity is still required.; AIMS: To compare the effects of different conservative treatments for hallux valgus deformity by using the method of network meta-analysis.; Study Design: A systematic review and network meta-analysis of randomized controlled trials identified by searching PubMed, EMBASE, MEDLINE, OVID, and CINAHL. The included studies should have the characteristics that: (1) participants with hallux valgus deformity of any age (2) conservative treatments (3) Reported the hallux valgus (HVA), the intermetatarsal angle (IMA), the score of the Visual Analog Scale, and the score of Foot Function Index.; Results: 11 studies were included in this review. The agreement between reviewers reached a kappa value of 0.75. The results of the network meta-analysis showed that a combination of exercise and toe separator, night splints, and dry needling are most likely to be the best choice for reducing the hallux valgus angle (HVA) and intermetatarsal angle, and toe separators (with or without exercise), dry needling, and manipulation (with or without ice treatment) have advantages in improving the subjective feeling of patients.; Conclusions: Multi-disciplinary conservative treatments have a great potential for hallux valgus deformity. More research with high-quality is needed to give a comprehensive and reasonable scheme of a holistic and long-term treatment protocol.

Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity with an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 25° to 14°, the first intermetatarsal angle from 12° to 8° and the DMAA from 15° to 5°. At the end of treatment, 94% of patients were classified as having grade 0 or I sesamoid lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.

ObjectiveThe treatment effect of orthoses for hallux valgus (HV) is unclear with little interventional studies, the design involves multiple complex factors, and therefore a systematic analysis with meta-analysis is necessary. The objective of this systematic review and meta-analysis is to determine whether current foot orthoses are effective in treating HV.DesignSystematic review with meta-analysis.Data sourcesElectronic databases (PubMed, Scopus, Cinahl and Medline) are searched up to February 2020.Eligibility criteria for selecting studiesInterventional studies with content focus on HV orthosis design and any of the outcomes related to effectiveness for treating HV are included. The standardised mean differences are calculated. The risk of bias in included studies is assessed using the Cochrane Collaboration’s risk of bias tools.ResultsIn total, 2066 articles are identified. Among them, nine are selected and quality rated, and data are extracted and closely examined. A meta-analysis is conducted, where appropriate. The main causes of potential bias are missing outcome data and outcome measurement error. The results show that orthosis with a toe separator has the best effect of correcting the HV angle (standardised mean difference: 0.50, 95% CI: 0.189 to 0.803).ConclusionThe orthoses design with a toe separator or an element that allows for the foot anatomic alignment is critical for reducing the HV angle and relieving foot pain. The results contribute to a better selection of treatment for patients.PROSPERO registration numberCRD42021260403.

Introduction: Hallux valgus is a multifactorial disease, and heredity is the main associated factor. Pain and discomfort when using closed-toed shoes occur in many cases, adversely affecting quality of life. Surgical treatment is indicated when pain and disability persist after conservative treatment. Currently, more than 150 surgical techniques are described for hallux valgus correction, with no consensus regarding the best treatment. With the advent of minimally invasive techniques for hallux valgus correction, Vernois developed the percutaneous chevron osteotomy. This technique allows up to 100% lateral translation of the contact area of the osteotomy. Objective: the objective of the present study was to assess the correction of radiographic parameters, clinical improvement and potential complications of the first 30 cases of moderate and severe hallux valgus operated on at our hospital using the percutaneous chevron technique. Methods: A total of 26 patients (30 feet) underwent surgery. The following parameters were measured in the pre- and postoperative periods: the first metatarsophalangeal (MTP) angle, the intermetatarsal angle between the 1st and 2nd metatarsals (IMA), the distal metatarsal articular angle (DMAA) and the pre- and postoperative American Orthopedic Foot and Ankle Society (AOFAS) scores, with a minimum follow-up period of 6 months. Results: The mean age of the patients was 52.3 years. During the preoperative period, the mean AOFAS score was 45.6; it increased to 90.3 after the procedure, indicating a statistically significant improvement. The mean MTP angle, IMA and DMAA were 29.7°, 14.2° and 14.2° before surgery and 12.8°, 8.2° and 11.1° after surgery, respectively. The improvements in the MTP angle and the IMA were also significant. There was no decrease in angles or worsening of AOFAS scores during follow-up. Conclusion: The percutaneous chevron technique was safe and effective for correcting cases of moderate and severe hallux valgus, with significant improvements in clinical and radiological parameters and a low rate of postoperative complications.

Abstract Purpose This study aimed to detect the effect of a modified chevron osteotomy on hallux valgus (HV) deformity at five-year follow up. Methods Twenty patients with symptomatic HV who underwent modified chevron osteotomy between June 2014 and January 2016 were included in the present study. The follow-up duration was more than five years. Each patient was evaluated preoperatively, six weeks postoperatively and five years postoperatively using the visual analog scale (VAS) pain score, the American Orthopaedic Foot & Ankle Society (AOFAS) score and cosmetic and radiological outcomes. Results The AOFAS score improved from 54.40 (± 4.58) preoperatively to 94.30 (± 2.15) six weeks postoperatively (p < 0.001) and 96.95 (± 1.54) five years postoperatively (p < 0.001). The VAS scores decreased from 6.30 (± 1.17)preoperatively to 0.15 (± 0.37) five years postoperatively (p < 0.001). The mean intermetatarsal angle improved from 16.00° (± 2.20°) preoperatively to 4.15° (± 1.22°) six weeks postoperatively (p < 0.001) and 4.40° (± 1.39°) five years postoperatively (p < 0.001). The mean HV angle also improved, from 32.70° (± 5.34°) preoperatively to 4.80° (± 1.40°) six weeks postoperatively (p < 0.001) and 5.20° (± 1.32°) five years postoperatively (p < 0.001). The cosmetic results were either excellent or good in 19 patients (95%). There was no recurrence in this study during the five postoperative years. Conclusion A modified chevron osteotomy can achieve successful correction of moderate-to-severe HV, with excellent outcomes at five-year follow up.

From 1986 to 1990, 42 feet in 30 patients had a combined chevron osteotomy and lateral release to correct their painful bunion deformity. Seventeen patients, 23 feet, were available for follow-up. The purpose of this study was to evaluate the outcome of this procedure and to determine the incidence of avascular necrosis. The patients were examined by an independent examiner, radiographs obtained, and questionnaires filled out. Avascular necrosis was determined using plain films read by a musculoskeletal radiologist who did not know the outcomes. The average age was 45 years at the time of the procedure. Average follow-up was 50 months. The preoperative intermetatarsal angle averaged 13° and the hallux valgus angle averaged 31°. At study follow-up, the intermetatarsal angle averaged 8° and the hallux valgus angle averaged 17.5°. The results were graded by the Mayo Clinic Forefoot Scoring System (75-point scale) and a subjective scoring system. Average postoperative Mayo Clinic score was 67. Fifteen feet were subjectively rated as excellent, six as good, and two as fair. Complications occurred in four feet. Hallux varus occurred in two feet, extension contracture in one foot, and an infection in one foot. None of the feet developed definite radiographic evidence of avascular necrosis. Distal chevron osteotomy combined with a lateral release for corrective bunion surgery has come under scrutiny, because of the risk of avascular necrosis of the first metatarsal head. However, our study showed no evidence of avascular necrosis on radiographs. In addition, 91% of patients had good to excellent results at an average 50-month follow-up.

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Loss of correction in hallux valgus (HV) deformity following distal chevron metatarsal osteotomy (DCO) has been demonstrated in short-term follow-up with HV recurrence rates of up to 75% reported in the long-term. The purpose of this study was to evaluate the radiographic effect of the DCO on the anatomic and mechanical axes of the first metatarsal. Our hypothesis was that patients undergoing DCO would have improvement in the mechanical metatarsal axis but worsening of the anatomic axis. Methods: This was a retrospective single surgeon case series of all patients who underwent DCO for HV between 2017 and 2019. Patients were included if they had both preoperative and postoperative weightbearing foot radiographs. The primary outcomes were the change in anatomic first-second intermetatarsal angle (a1-2IMA, defined by the metatarsal diaphyseal axis) and the change in mechanical first-second intermetatarsal angle (m1-2IMA, defined by the axis from the center of the metatarsal head to the metatarsal base). Secondary outcomes included the change in hallux valgus angle (HVA) and medial sesamoid position (medial sesamoid in relation to the mechanical axis of the metatarsal). Change in second-third intermetatarsal angle (2-3IMA, defined by the metatarsal diaphyseal axis) was measured to control for any inconsistencies in radiographic technique. Given the relatively small patient cohort, the non-parametric Wilcoxon signed rank test and Mann Whitney U test were used for statistical analysis. Results: 41 feet were included for analysis with a mean follow-up of 20.4 weeks. The a1-2IMA increased significantly (mean, 4.0 degrees, p<0.001) while the m1-2IMA decreased significantly (mean, 4.6 degrees, p<0.001) following DCO. There was a significant improvement in HVA (mean, 13.2 degrees, p<0.001). No changes were noted in 2-3IMA (mean, 0.0 degrees, p=0.834). (Table 1) Medial sesamoid position was improved in 22 feet (53.7%). Patients with improved sesamoid position were noted to have a significantly larger decrease in m1-2IMA (mean, 5.3 versus 3.8 degrees, p=0.01) and a smaller increase in a1-2IMA (mean, 3.4 versus 4.7 degrees, p=0.02) compared to patients with no improvement in sesamoid position. Conclusion: Distal chevron osteotomy for HV is associated with an increase in the anatomic intermetatarsal angle despite improvements in the m1-2IMA, HVA and medial sesamoid position. Patients with improved sesamoid position were associated with greater correction of the mechanical first metatarsal axis. Our findings may suggest the presence of intermetatarsal instability, which could limit the power of DCO in HV correction for more severe deformities and provide a mechanism for HV recurrence.
