ABSTRACT
Objectives The aim of the present article is a clinical and radiographic evaluation of scaphoid nonunion with humpback deformity using an iliac graft and a volar plate. Methods Eight patients were followed-up prospectively, all male, with a mean age of 39.6 years old, with scaphoid waist nonunion, with an average of 19 months of trauma without previous surgery. The patients were treated with a graft removed from the iliac crest and a 1.5 mm blocked volar scaphoid plate (Medarthis AG, Basel, Switzerland). The patients were followed-up with radiographic evaluations and computed tomography (CT) scans in the preoperative period and 1 month, 3 months, 6 months and 1 year after the operation. The carpal height and the scaphosemilunar and intrascaphoid angles were measured preoperatively, 3 months, and 1 year postoperatively. The function was assessed preoperatively and repeated 1 year postoperatively using the Disabilities of the Arm, Shoulder, and Hand (DASH) and Patient-related Wrist Evaluation (PWRE scores), as well as by measurement of forceps clamp and wrist and thumb range of motion. Results All cases were consolidated, with an average time of 3.38 months. Two complications were observed: an infection of the iliac surgical wound and a plaque element placed in the scapholunate space. Two patients opted to remove the implant because they had a painful click at maximum wrist flexion. There was improvement in the parameters of wrist and thumb range of motion and pinch strength in all measurements, with statistical significance for the PRWE and the scapholunate angle. Conclusion Although our sample was small, we achieved consolidation in all cases; the complications were expected in the literature and there were improvements in the radiographic patterns, in the functional assessment, and in the pain scale of our patients.
ABSTRACT
OBJECTIVE: To analyse the construct validity, test-retest reliability and responsiveness of the Brazilian version of Quick-DASH (QD-Br) in patients with upper limb disorders. METHOD: Participants completed the full Brazilian DASH, the QD-Br and the SF-12 Brazil questionnaires at the beginning of treatment, after 48-72h and the after 2-12 months. Construct validity was analysed by Pearson's correlation coefficient (r). To evaluate the test-retest reliability we used the Intraclass Correlation Coefficient (ICC) and the Cronbach's alpha coefficient to test the internal consistency. Responsiveness was analysed by Standardized Response Mean (SRM) and Effect Size (ES). The Minimal detectable change (MDC) score was based upon calculations of the standard error of measurement (SEM), confidence interval of 95%. RESULTS: The construct validity presented strong direct correlation with the total QD-Br score and the Brazilian DASH (r = 0.91), a moderate inverse correlation between the total QD-Br score and the physical component of the SF- 12 Brazil (r = -0.55) and weak inverse correlation between the QD-Br and the mental component of SF-12 Brazil (r = -0.49). The ICC test-retest showed good reliability of 0.81 (0.72-0.87). QD-BR presented high responsiveness, with ES of 1.06 and SRM of 0.94. The MDC was 17.27 points. CONCLUSION: These results provide evidence that the QD-Br was a valid, reliable and responsive instrument when utilized in patients with upper limb traumatic and no-traumatic disorders in the Brazilian population.

Lesões podem gerar consequências funcionais e mudanças de vida para o indivíduo. Além do exame físico, a aplicação de questionários de autorrelato são fundamentais para a tomada de decisão, determinação do prognóstico e avaliação da eficácia do tratamento. O Patient Specific Functional Scale (PSFS) é um questionário individual que avalia o estado funcional do indivíduo. Suas vantagens propostas incluem sua ampla aplicabilidade, facilidade de administração, e adequada responsividade para análise da evolução funcional. Entretanto, esta escala ainda não está disponível na versão em português-brasileiro. Objetivo: Realizar a tradução e adaptação transcultural do questionário e analisar sua validade, confiabilidade e responsividade em pacientes com lesões do membro superior. Métodos: O PSFS-Br foi desenvolvido usando diretrizes padronizadas e o processo de tradução ocorreu em 5 etapas. Após a versão definitiva, 100 pacientes com lesões do membro superior foram recrutados e responderam o PSFS-Br, Quick-DASH-Br a Escala Visual Analógica em três ocasiões. Resultados: A compreensão adequada do instrumento pela população alvo resultou em boa validade de face. O PSFS-Br, quando comparado ao QuickDASH-Br, apresentou validade de construto fraca r = -0,36, excelente confiabilidade teste-reteste (ICC = 0,91) e apresentou alta responsividade com Tamanho do Efeito(TE) = 1,85, Média da resposta Padronizada (MRP) = 2, 75, Erro padrão de medida (EPM) = 0,36 e Minima diferença dectável (MDD) = 1,5. Conclusão: Este estudo demostrou que o PSFS-Br é uma ferramenta válida, confiável e responsiva para pacientes brasileiros com lesões do membro superior.
Injuries can lead to functional consequences and changes in the lives of individuals. In addition to physical examination, a self-report questionnaire application is critical for decision making, prognosis determination, and treatment evaluation. The Patient Specific Functional Scale (PSFS) is an individual questionnaire that evaluates the individuals functional status and its advantages, which can be applied, ease of administration and responsive. However, this scale is not yet available in the Portuguese-Brazilian version. Objective: To perform a translation and cross-cultural adaptation of the questionnaire and to analyze its validity,reliability and responsiveness in patients with upper limb injuries. Methods: PSFS-Br was developed using standardized guidelines and the translation process took place in 5 steps. After a definitive version, 100 patients with upper limb injuries were recruited and answered by PSFS-Br, Quick-DASH-Br and Visual Analogue Scale on three occasions. Results: Proper understanding of the instrument by the target population resulted in good face validity. PSFS-Br, when compared to QuickDASH-Br, shows poor construct validity r = -0.36, excellent retest test reliability (ICC = 0.91) and high responsiveness with Effect Size (ES) = 1.85, Standand response mean (SRM) = 2.75, Standard Error of Measure (SEM) = 0.36 and Minimal Chande Diference (MCD) = 1.5. Conclusion: PSFS-Br is a valid, reliable and responsible tool for Brazilian patients with upper limb injuries.

BACKGROUND: Many tools have been described for outcome assessment after nerve repair. The Patient-Rated Wrist and Hand Evaluation (PRWHE) have been shown to be valid for several hand conditions. OBJECTIVES: To explore the construct validity of the PRWHE in comparison to cold intolerance, pain and dysfunction questionnaires; the Rosén score and its subcomponents; and threshold sensibility, dynamometry and dexterity tests for nerve repair of the hand. STUDY DESIGN: Clinical measurement. METHODS: Construct validity was analysed through Pearson's correlation coefficient in a convenience sample of 32 adult patients after long-term median and ulnar nerve repair. RESULTS: The PRWHE total score was highly to moderately associated with the Disability of Arm, Shoulder and Hand (râ¯=â¯0.83), Cold Intolerance Symptom Severity (râ¯=â¯-0.60) and McGill's Pain (râ¯=â¯0.58) questionnaires. In addition, it was correlated to motor (râ¯=â¯-0.55) and sensor subdomains (râ¯=â¯-0.56) of the Rosén score. Substantial to high associations were found for the motor, sensory impairment and dexterity test. CONCLUSIONS: The PRWHE was shown to be valid, based on construct validity, for patients with nerve repair of the hand.
