BACKGROUND: Surgical management of hallux valgus and hallux rigidus is influenced by deformity severity, surgeon training, and evolving techniques. Previous surveys in Australia (2012), Switzerland (2015), and Israel (2023) using identical hypothetical cases demonstrated marked regional differences and a recent rise in minimally invasive Chevron-Akin (MICA). Whether these advances have altered contemporary Swiss practice remains unclear. METHODS: An electronic survey replicating the original questionnaire was distributed to members of the Swiss Foot and Ankle Society. Three standardized clinical cases were presented: mild hallux valgus, severe hallux valgus, and hallux valgus et rigidus. Respondents selected nonoperative versus operative management and specified procedures and fixation methods. Demographics, subspecialty training, and surgical volume were recorded. Current results were compared with prior Swiss data to assess temporal change. RESULTS: Eighty surgeons completed the survey (94% foot and ankle specialists). For mild hallux valgus, 87.7% recommended surgery; Scarf osteotomy remained most common (49.4%), followed by Chevron (21.0%) and Minimally Invasive Hallux Valgus correction (14.8%). Minimally Invasive adopters were predominantly mid-career (83% aged 41-50), high-volume surgeons. For severe hallux valgus, 95.1% favoured surgery; MTPJ arthrodesis was preferred (50.6% isolated; 11.1% with Lapidus), while Minimally Invasive Hallux Valgus correction was rarely chosen (2.5%). In hallux valgus et rigidus, 96% selected MTPJ fusion, most commonly plate-and-screw fixation (45.1%). Compared with 2015, fixation strategies evolved, yet procedure selection remained largely unchanged. CONCLUSION: Despite global expansion of minimally invasive bunion surgery, Swiss surgeons continue to favour established open techniques, particularly Scarf osteotomy and fusion-based strategies. Adoption of MIS remains limited and concentrated among high-volume, mid-career specialists, indicating a cautious national diffusion pattern. LEVEL OF EVIDENCE: IV, survey study.
BACKGROUND: Hallux valgus is classified as an abnormal deviation of the great toe (hallux) towards the midline of the foot. OBJECTIVES: To identify and evaluate the evidence from randomised trials of interventions used to correct hallux valgus. SEARCH STRATEGY: Medline (1966-October 1998), Embase (1980-1998), Cinahl (1982-1998), Amed (1993-1998), the Cochrane Controlled Trials Register, the Cochrane Musculoskeletal Injuries Trials Register and bibliographies of identified trials were searched. Hand searching of podiatry journals was undertaken. Date of the most recent search: October 1998. SELECTION CRITERIA: Randomised or quasi-randomised trials of both conservative and surgical treatments of hallux valgus. Excluded were studies comparing areas of surgery not specific to the control of the deformity such as use of anaesthetics or tourniquet placement. DATA COLLECTION AND ANALYSIS: Methodological quality of trials which met the inclusion criteria was independently assessed by two reviewers. Data extraction was undertaken by one reviewer and confirmed by another. The trials were grouped according to the interventions being compared, but the dissimilarity in the comparisons prevented pooling of results. MAIN RESULTS: The methodological quality of the 12 included trials was poor and trial sizes were small. Two trials involving 150 patients evaluated conservative treatments. There was no difference in outcomes between treatment and no treatment. Two trials involving 133 patients compared Keller's arthroplasty with other surgical techniques. In general, there was no advantage in using Keller's over the other techniques, particularly in terms of range of motion and intermetatarsal angle. Three trials involving 205 patients compared chevron (and chevron-type) osteotomy with other techniques. The chevron osteotomy offered no advantages in these trials. For some outcomes, other techniques gave better results. Three trials involving 157 patients compared outcomes between original operations and surgeon's adaptations. There was no advantage found for any of the adaptations. Two trials involving 95 patients evaluated methods of post-operative rehabilitation. The use of continuous passive motion appeared to give an improved range of motion and earlier recovery following surgery; early weightbearing was not found to be detrimental to final outcome. REVIEWER'S CONCLUSIONS: There is insufficient evidence from randomised trials to determine which methods of either conservative, operative or post-operative treatment are the most appropriate for the hallux valgus. It is notable that the numbers of patients remaining dissatisfied at follow-up were consistently high (25 to 33%), even when the hallux valgus angle and pain had improved. Assessment of future research should focus on evaluating basic intervention types in eligible patients with similar degrees of deformity. Future research should include patient-focused outcomes, standardised assessment criteria and longer surveillance periods.
Distal chevron osteotomy is a widely employed procedure for correction of mild to moderate hallux valgus. The author has modified the angle of the osteotomy to provide even greater stability and allow larger displacements of the distal fragment. This modification allows the correction of a greater degree of hallux valgus than originally described for the technique. This modification is relatively simple and increases the stability compared to the original publication.
