Functional Evaluation and Pain Symptomatology of the Foot and Ankle in Individuals with Severe Obesity - Controlled Transversal Study / Avaliação funcional e de sintomatologia dolorosa do pé e tornozelo em indivíduos com obesidade grave - Estudo controlado transversal

Abstract Objective The present study aims to evaluate the prevalence of foot and ankle pain complaints, radiographic parameters, and functional performance in subjects with severe obesity (body mass index [BMI] > 40) who are candidates to bariatric surgery. Methods Forty severely obese patients were evaluated at a bariatric surgery outpatient facility. These severely obese subjects (BMI > 40) were divided into two subgroups: those with BMI < 50 (n = 24) and BMI > 50 (n = 16). These patients were compared with a control group of 42 volunteers with a mean BMI value of 24. The following parameters were assessed: foot pain (according to the visual analog scale [VAS]), functional performance (according to the American Orthopeadic Foot and Ankle Society [AOFAS] scale, including forefoot, midfoot and hindfoot domains), age, gender, hallux metatarsal-phalangeal angle, hallux intermetatarsal angle, talocalcaneal angle, calcanean pitch angle and Meary angle. Results Incidence of foot pain was higher in the severely obese group compared with the control group (p < 0.0001; odds ratio [OR]: 4.2). Functional performance according to the AOFAS scale was lower in obese subjects compared with the control group (p < 0.0001; OR for hindfoot, 4.81; OR for midfoot, 3.33). Conclusion The incidence of foot pain was higher in the group of severely obese patients compared with the control group. According to the AOFAS scale, functional forefoot, midfoot and hindfoot performance was worse in severely obese individuals.

Resumo Objetivo Avaliar a prevalência de queixas álgicas no pé e tornozelo, parâmetros radiográficos e o desempenho funcional de indivíduos com obesidade grave, Índice de Massa Corpórea (IMC) com valor > 40 e indicação de cirurgia bariátrica. Métodos Foram avaliados 40 pacientes com obesidade grave acompanhados em ambulatório de cirurgia bariátrica. Este grupo de obesos graves (IMC > 40) foi subdividido em dois subgrupos: obesos com IMC < 50 (n = 24); e outro de obesos com IMC > 50 (n = 16). Foi realizada comparação com grupo controle de 42 indivíduo voluntários com IMC médio de 24. Foram avaliados a presença de dor no pé pela escala visual (EVA), o desempenho funcional pela escala da Associação Americana de Cirurgia do Pé e Tornozelo (AOFAS, na sigla em inglês) (domínios antepé, mediopé e retropé), idade, gênero, ângulo (âng) metatarso-falangeano do hálux, âng intermetatarsal do hálux , âng talocalcaneano, "pitch" calcaneano e âng de Meary. Resultados Foi observada maior incidência de dor no pé no grupo de obesos graves em relação ao controle (p < 0,0001, razão de chances [odds ratio, OR]: 4,2). O desempenho funcional pela escala AOFAS foi inferior no grupo de obesos em relação ao controle (p < 0,0001, retropé com OR = 4,81; mediopé com OR = 3,33). Conclusão Houve maior incidência de dor no pé no grupo de obesos graves em relação ao controle. Houve pior desempenho funcional pela escala AOFAS nas regiões do antepé, mediopé e retropé no grupo de obesos graves.

Tratamiento quirúrgico del Hallux Valgus moderado y severo: osteotomía metatarsiana proximal y liberación distal de partes blandas / Surgical Treatment of Moderate to Severe Hallux Valgus: Proximal Metatarsal Osteotomy and Distal Soft Tissue Release

Objetivo: evaluar los resultados clínicos y radiológicos obtenidos con la combinación de la osteotomía proximal del primer metatarsiano y la liberación distal de las partes blandas según técnica de Mann-Coughlin en el tratamiento del hallux valgus moderado y severo. Métodos: estudio retrospectivo en 16 pacientes (30 pies) con hallux valgus moderados y severo, operados en dos Centros Diagnóstico Integral del Estado Apure, en la República Bolivariana de Venezuela, todos por el mismo cirujano, en el período comprendido desde marzo 2009 hasta diciembre 2012. Solo 4 pacientes no continuaron en el seguimiento. Se evaluaron los resultados clínicos y radiográficos. Resultados: se encontró una mejoría promedio de 87,5 puntos según la Escala de la Sociedad Americana de Ortopédicos de Tobillo y Pie (AOFAS por sus siglas en inglés). El ángulo del hallux valgus mejoró de 34,8° promedio a 16,6° y el ángulo intermetatarsiano mejoró de 16,2° a 8,8° después de la cirugía. No hubo hallux varus y solo 2 pacientes tuvieron deshicencia de la herida quirúrgica y un paciente aflojamiento de la aguja Kirschner. Conclusiones: la osteotomía proximal del primer metatarsiano combinada con la liberación distal de partes blandas es una buena opción para la corrección quirúrgica en el tratamiento del hallux valgus moderado y severo, es sencilla para reproducir y presenta similares complicaciones que otras técnicas(AU)

Objective: Evaluate clinical and radiological results obtained with the combination of the first metatarsal osteotomy proximal and distal soft release according Mann-Coughlin technique in the treatment of moderate to severe hallux valgus parts. Methods: A retrospective study was conducted on 16 patients (30 feet) with hallux moderate and severe valgus. They underwent surgery at two Comprehensive Diagnostic Centers in Apure State, in the Bolivarian Republic of Venezuela, by the same surgeon from March 2009 to December 2012. Only four patients did not continue to follow up. Clinical and radiographic results were evaluated. Results: an average of 87.5 points improvement was found according to the scale of the American Society of Orthopaedic Foot and Ankle (AOFAS for its acronym in English). The hallux valgus angle improved from 34.8° to 16.6° and average intermetatarsal angle improved from 16.2° to 8.8° after surgery. There were no hallux varus. Only two patients had dehiscence of the surgical wound, and a patient had loosening of the Kirschner needle. Conclusions: the proximal osteotomy of the first metatarsal combined with distal soft tissue release is a good choice for surgical correction in the treatment of moderate to severe hallux valgus, it is easy to reproduce and it has similar complications than other techniques(AU)
