Objective: To evaluate the results from patients with lateral epicondylitis following surgical treatment using the arthroscopy technique. Methods: Twenty patients underwent surgery using the arthroscopic technique. Their ages ranged from 19 to 54 years (average of 41 years and eight months). Twelve (60%) of them were female and eight (40%) were male. The minimum follow-up period was 12 months and the maximum was 48 months, with an average of 20 months. All the cases were refractory to conservative treatment (rest and physiotherapy), with previous clinical treatment times ranging in duration from six to 136 months. To evaluate the results, we used the criteria of the American Medical Association (AMA), as modified by Bruce. Results: We obtained 13 excellent results (65%) and seven moderate results (13%), with just one complication (reflex sympathetic dystrophy). This was the only patient who reported dissatisfaction. Conclusion: Surgical treatment of the lateral epicondylitis of the elbow using arthroscopy was a good option for 65% of the cases.

IntroductionFractures of the diaphysis of the clavicle are common; however, treatment guidelines for this condition are lacking. Surgery is associated with a lower risk of non-union and better functional outcomes but a higher risk of complications. Open reduction and internal fixation with plates and screws are the most commonly performed techniques, but they are associated with paraesthesia in the areas of incisions, extensive surgical exposure and high rates of implant removal. Minimally invasive techniques for treating these fractures have a lower rate of complications. The aim of this study is to evaluate which surgical treatment option (minimally invasive osteosynthesis or open reduction and internal fixation) has better prognosis in terms of complications and reoperations.Methods and analysisThe study proposed is a multicentric, pragmatic, randomised, open-label, superiority clinical trial between minimally invasive osteosynthesis and open reduction and internal fixation for surgical treatment of patients with displaced fractures of the clavicle shaft. In the proposed study, 190 individuals with displaced midshaft clavicle fractures, who require surgery as treatment, will be randomised. The assessment will occur at 2, 6, 12, 24 and 48 weeks, respectively. The primary outcome of the study will be the number of complications and reoperations. For sample size calculation, a moderate effective size between the techniques was considered in a two-tailed test, with 95% confidence and 90% power. Complications include cases of infection, hypertrophic scarring, non-union, refracture, implant failure, hypoesthesia, skin irritation and shoulder pain. Reoperations are defined as the number of surgeries for pseudoarthrosis, implant failure, infection and elective removal of the implant.Ethics and disseminationStudy approved by the institutional ethics committee (number 34249120.9.0000.5505—V.3). The results will be disseminated by publications in peer-reviewed journals and presentations in medical meetings.Trial registration numberRBR-3czz68)/UTN U1111-1257-8953.

Resumo Objetivo Avaliar os resultados funcionais e radiográficos do tratamento cirúrgico realizado em um grupo de pacientes com fratura multifragmentada da diáfise de clavícula, pela técnica minimamente invasiva, em seguimento mínimo de 12 meses. Métodos Estudo observacional longitudinal de 32 pacientes consecutivos (31 do sexo masculino, idade média 41 anos) com fratura multifragmentada da diáfise da clavícula tratados cirurgicamente pela técnica minimamente invasiva de osteossíntese com placa de reconstrução de 3,5 mm na posição superior, avaliados clínica e radiologicamente, com seguimento mínimo de 1 ano Resultados Trinta pacientes (93,72%) evoluíram com consolidação da fratura em tempo médio de 17 semanas (entre 12 e 24 semanas). O tempo de seguimento médio foi de 21 meses (variando de 12 a 45 meses). Não houve quebra de implantes ou pseudoartroses. Não houve queixa de parestesia na região das incisões cirúrgicas. O ombro tratado cirurgicamente apresentou menor elevação passiva e maior comprimento da clavícula (p < 0,05) em relação ao contralateral. Na avaliação funcional, encontramos um valor médio de Disfunções do Braço, Ombro e Mão (DASH, na sigla em inglês) = 1,75, sendo o mesmo considerado satisfatório. Idade > 60 anos apresentou correlação negativa com escore DASH (p < 0,05). Conclusão A técnica minimamente invasiva de osteossíntese mostrou-se satisfatória para o tratamento da fratura multifragmentada da diáfise da clavícula, com elevada taxa de consolidação e baixo índice de complicações.

Objectives: This study aimed to evaluate the functional results of the treatment protocol for the treatment of transolecranon fracture-dislocation, by surgical reduction and osteosynthesis with plate and screws, in patients attended at a referral hospital for orthopedic trauma, with a minimum follow-up period of six months. Methods: Twenty-five individuals treated surgically from January 2014 to November 2018 were selected for a primary observational longitudinal study using questionnaires to assess upper limb and elbow function (DASH and MEPS), quality of life (SF-12), pain (visual analog scale - VAS), and radiographic evaluation in anteroposterior and lateral views of the elbow. Results: Fifteen patients were male, and the mean age was 46.8 years. All participants had their fractures consolidated, with no radiolgraphic signs of implant failure, or degenerative arthritis. Mean range of motion was reduced relative to the contralateral limb: 102.6º for flexion-extension and 132.8º for pronation-supination. The mean MEPS and DASH scores were 89.6 and 16.5 respectively. There was no residual pain in 84% of the cases according to the VAS. Conclusion: The surgical treatment proposed for transolecranon fracture-dislocations showed satisfactory results according to MEPS, DASH scores and quality of life measures. Evidence Level IV; Retrospective observational study.
