Objective: To evaluate the correlation between postoperative quality of life and the severity of hallux valgus deformity. Methods: A total of 23 patients underwent moderate (n = 14) and severe (n = 9) hallux valgus (HV) surgical correction with the Scarf technique between January 2010 and December 2012. The mean follow-up time was 60 months. Participants answered the SF-36 quality of life assessment questionnaire and their radiographs were evaluated at three different moments (preoperative, 1 and 5 years after surgery). Statistical analysis was performed with a maximum 5% significance level. Results: The sample consisted of two men and 21 women, aged 58.7.SF-36 mean value was 75.73 and the metatarsophalangeal and interphalangeal angles improved significantly at the three moments (p < 0.05). SF-36 showed no statistical difference between patients with moderate or severe HV (p > 0.05). No correlations were found between quality of life and pre and postoperative radiographic angles. Conclusion: Patients with moderate and severe hallux valgus submitted to surgical correction had a very good quality of life and a significant improvement in radiographic parameters. However, these variables were not correlated. Level of Evidence II, Retrospective study.

Objetivos: Avaliar sinais radiográficos de diminuição do arco longitudinal medial do pé com base em exames realizados antes e depois da cirurgia de transferência do tibial posterior para tratar o deficit motor ocasionado pela lesão completa do nervo fibular. Métodos: Estudo descritivo e analítico com base em informações colhidas em prontuários. Foram inclusos os pacientes com no mínimo dois anos de cirurgia e avaliadas as radiografias antes e depois do procedimento. Nas radiografias em incidência anteroposterior do pé foram avaliados os ângulos talocalcâneo, talometatarsal e a congruência talonavicular. Na incidência de perfil verificou-se os ângulos talocalcâneo, Meary e pitch do calcâneo. Foram colhidos dados referentes ao perfil do paciente, mecanismo de trauma e tempo de seguimento. Resultados: Um paciente apresentou radiografia sugestiva de diminuição do arco plantar após a transferência do tibial posterior. A variação angular ocorrida nos pacientes ainda que dentro da normalidade não apresentou variação estatisticamente significante. Conclusão: Não houve redução do arco longitudinal do pé de forma estatisticamente significante nos pacientes estudados.

Introduction: Several factors, including diabetes and smoking, increase the risk of and predisposition for complications of foot and ankle surgeries; however, studies assessing the effects of obesity remain scarce. The objective of this study is to assess the effects of obesity on functional outcomes of flexor hallucis longus (FLH) tendon transfer surgery in patients with chronic Achilles tendinopathy. Methods: A retrospective study was performed with patients aged 18 years or older who underwent FHL tendon transfer between March 2010 and May 2015. The characteristics recorded were sex, age, body mass index (BMI), American Orthopedic Foot and Ankle Society (AOFAS) score, Foot and Ankle Outcome Score (FAOS) and ankle plantar flexion and dorsiflexion strength, assessed using an isokinetic dynamometer. Results: The sample had 24 participants (13 women and 11 men) with a mean age of 55.7 years; among them, 13 were obese (BMI>=30), and 11 were nonobese (BMI<30). After a mean follow-up time of 66 months, the FAOS of the sample increased from 28 to 91 points (p=0.000). No significant difference in the postoperative AOFAS score or FAOS was found between the subgroups (p>0.05), with values of 83 and 86.7 points (AOFAS) and 92.72 and 90 points (FAOS) for obese and nonobese patients, respectively. The comparison of the strength of each motion revealed no significant difference (p>0.05) between subgroups. There was no association between BMI and postoperative functional outcomes (AOFAS score and FAOS) (p>0.05) or correlation between BMI and the strength of the operated ankles. Conclusion: Our findings indicate that flexor hallucis longus tendon transfer surgery in Achilles tendinopathy is effective for obese and nonobese patients based on the AOFAS and FAOS scores and dynamometry results.

Objective: A) To evaluate the reliability of a new technique for the measurement of both intermetatarsal and hallux valgus angles. B) To evaluate whether this technique can be performed with the aid of a smartphone application. Methods: Preoperative radiographs of 30 patients were evaluated by four observers, two experienced surgeons and two surgeons in training. They performed measurements of the intermetatarsal angle and hallux valgus angle using the classical method and using the new method, both employing a goniometer and a smartphone application. Analysis of agreement was done by quantifying the raw agreement and calculating the intraclass correlation coefficient (ICC). Results: The hallux valgus angle presented excellent agreement (ICC>0.80) both using the traditional method and the point connection method, while the intermetatarsal angle presented a very good agreement (0.60<ICC≤0.80) in both methods. Conclusion: The point connection technique showed good concordance rates when measured by smartphone applications, although it did not prove to be superior to the traditional one.
