Minimally invasive Chevron-Akin (MICA) osteotomies without Akin fixation in hallux valgus correction: a case series with 2-year follow-up.

PURPOSE: The minimally invasive Chevron-Akin (MICA) is considered the third generation of minimally invasive hallux valgus (HV) surgery, and its original description included fixation of the Akin osteotomy with a screw. The aim of this study is to evaluate a series of patients undergoing HV correction using the MICA technique without screw fixation of the Akin osteotomy. METHODS: We retrospectively evaluated 58 consecutive patients who underwent surgical correction for HV between August 2018 and March 2020. A total of 69 feet were evaluated with a minimum follow-up of 2 years. Clinical outcomes such as pain (VAS), function (AOFAS), range of movement, criteria personal satisfaction and complications were evaluated. RESULTS: The AOFAS score (mean ± standard deviation) significantly improved from 57.0 ± 8.6 preoperatively to 93.9 ± 8.7 postoperatively (p < .001) with a minimum follow-up of 2 years. The VAS score improved from 6.0 ± 1.8 preoperatively to 0.6 ± 1.4 at 2-year follow-up (p < .001), and the hallux valgus angle reduced from 39.7 ± 6.9 to 8.9 ± 9.0 (p < .001). The majority of patients (95.6%) reported the result as excellent or good, and the most common complication was the need to remove the screw (7.2%). CONCLUSIONS: The use of MICA without Akin osteotomy fixation resulted in successful correction of hallux valgus with improvements in clinical and radiographic parameters. LEVEL OF EVIDENCE: IV, case series.

Treatment of Morton's neuroma with minimally invasive distal metatarsal metaphyseal osteotomy (DMMO) and percutaneous release of the deep transverse metatarsal ligament (DTML): a case series with minimum two-year follow-up.

BACKGROUND: The optimal treatment of symptomatic Morton's neuroma remains unclear; conservative methods are sometimes ineffective and neurectomy has significant rates of patient dissatisfaction. The aim of this study was to evaluate the outcome of minimally invasive distal metatarsal metaphyseal osteotomy (DMMO) and percutaneous release of the deep transverse metatarsal ligament (DTML) in patients with Morton's neuroma. METHODS: Between January 2018 and November 2019, 27 patients (29 feet) diagnosed with Morton's neuroma after clinical and radiological evaluation underwent DMMO and percutaneous DTML release. The primary clinical outcomes were pain (VAS) and function (AOFAS score). Secondary outcomes included patient satisfaction, complications, and radiographic outcomes. Patients were followed up for a minimum of two years. RESULTS: The median age of the participants was 66 years (range 48-79) and the follow-up time was 28 months (24-47). There was a decrease of 5.7 points in the VAS for pain (p < .001) and an increase of 19.9 in AOFAS (p < .001) after the surgical procedure. There was one case of superficial infection and one patient required resection of the neuroma (neurectomy). The majority of patients (89.7%) were satisfied and considered the procedure outcome as excellent or good. CONCLUSION: Treatment of Morton's neuroma with minimally invasive distal metatarsal metaphyseal osteotomy and percutaneous release of the deep transverse metatarsal ligament showed significant improvement in pain and function with a low incidence of complications and a high rate of personal satisfaction.

Which clinical outcome scores are more frequently used in the literature on osteochondral lesions of the talus? a systematic review / Quais escores de desfechos clínicos são usados com mais frequência na literatura lesões osteocondrais do tálus? uma revisão sistemática

ABSTRACT Objective: This study aimed to identify the most used scales in the assessment of the clinical outcomes for the treatment of osteochondral lesions of the talus. Methods: We performed a systematic review of the PubMed/MEDLINE databases from September 1999 to September 2019, based on the guidelines established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The research strategy was: osteochondral [All Fields], AND ("talus" [MeSH Terms] OR "talus" [All Fields]) AND lesion [All Fields]. Of the 364 articles found in the literature, 166 (45%) were included in the study and 198 (55%) excluded. In total, 23 clinical assessment tools were used in the studies. Results: We found 49.4% of the studies to use the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS Ankle-Hindfoot Scale) and 29.5% the Visual Analogue Scale (VAS). Conclusion: The use of AOFAS increased in relation to VAS in the last 6 years (p = 0.046), and these two scales, either alone or combined, were the most used for studying osteochondral lesions of the talus. Level of Evidence III, Systematic Review of Level II studies.

RESUMO Objetivo: Este estudo propõe revisar sistematicamente a literatura para identificar as escalas mais utilizadas da avaliação clínica de resultados do tratamento das LOTs. Métodos: Foi realizada revisão sistemática das bases de dados do PubMed/MEDLINE, desde setembro de 1999 a setembro 2019 baseado nas diretrizes PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses). A estratégia de pesquisa foi: osteochondral [All Fields], AND ("talus" [MeSH Terms] OR "talus" [All Fields]) AND lesion [All Fields]. De 364 artigos, foram incluídos no estudo 166 (45%) e excluídos 198 (55%). Foram observadas 23 escalas de avaliação clínica utilizadas. Resultados: A escala AOFAS e EVA de dor foram as mais utilizadas, ocorrendo em 49,4% e 29,5% dos artigos, respectivamente. Foi observado aumento de uso de AOFAS e diminuição EVA nos últimos 6 anos (p = 0,046). Conclusão: As ferramentas Escala AOFAS e EVA para dor demonstraram ser as mais usadas na literatura para avaliação de resultados do tratamento da lesão osteocondral de tálus, tanto isoladamente, quanto combinadas. Nível de Evidência III, Revisão Sistemática de Estudos de Nível II.
