Translation and Cross-cultural Adaptation of the "Thumb Disability Exam - TDX" questionnaire into Brazilian Portuguese / Tradução e adaptação cultural do questionário "Thumb Disability Exam - TDX" para o português brasileiro

Abstract Objective To perform the translation, cultural adaptation and validation of the Thumb Disability Exam (TDX) questionnaire into Brazilian Portuguese. Method The questionnaire was translated, with reverse translation. The translations were evaluated and synthesized by a committee, resulting in the THUMB DISABILITY EXAM - BRASIL (TDX-BR). A total of 31 patients diagnosed with rhizarthrosis were selected and answered the questionnaire. Quality parameters were evaluated, such as internal consistency, reproducibility and ceiling and floor effect. Results The questionnaires were translated and adapted according to defined protocols. Internal consistency, through the Cronbach α coefficient for the TDX-BR, was 0.962. The reliability of the questionnaire, through intraclass correlation coefficient (ICC )also proved to be quite high, with κ = 0.953 (0.947-0.959). Agreement, measured using the standard error of measurement, remained with standard values < 5%. There was no ceiling and floor effect. Conclusion Through specific methodology, we consider TDX-BR as translated and valid for the Portuguese language of Brazil.

Translation and cross-cultural adaptation of "Trapeziometacarpal Arthrosis Symptoms and Disability—TASD" into Brazilian Portuguese

Abstract Background: Osteoarthritis is the most common form of hand arthritis and arthritis of the carpometacarpal joint of the thumb is a potentially limiting disease. There is no homogeneity in the evaluation of outcomes for the rhizarthrosis treatment. In an attempt to standardize the evaluation of results, some subjective questionnaires, non-specific, were used to evaluate rhizarthrosis. Trapeziometacarpal Arthrosis Symptoms and Disability (TASD) was described by Becker et al.with the purpose of evaluating symptom intensity and degree of disability, as to compare results after treatment. Our objective is to translate, validate and do the cultural adaptation of the questionnaire TASD into the Brazilian Portuguese. Methods: The questionnaire was translated, with reverse translation. The translations were evaluated and synthesized by a committee, arriving at TASD-BR. Thirty-one patients with a diagnosis of rhizarthrosis answered the questionnaire. We evaluated, the internal consistency, reliability, agreement and ceiling and floor effect for validation. Results: The questionnaires were translated and adapted according to defined protocols. The internal consistency, through Cronbach's α coefficient for TASD-BR, was 0.927. The questionnaire's reliability, through the Intraclass Correlation Coefficient, was also shown to be quite high, with κ = 0.961 (0.954-0.967). The agreement, measured through the Standard Error Measurement, remained with standardized values below 5%. There was no ceiling and floor effect. Conclusion: Through specific methodology we consider TASD-BR translated and valid for the Brazilian Portuguese.

Trapeziectomy with Ligament Reconstruction and Interposition Arthroplasty Using the Palmaris Longus Tendon: An Average 5-Year Follow-up

BACKGROUND: Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of trapeziometacarpal osteoarthritis. We modified the LRTI, using the palmaris longus (PL) tendon instead of the FCR tendon. The aim of this retrospective study was to evaluate the clinical outcomes of trapeziectomy with our modified LRTI procedure at a mean follow-up of 5 years. METHODS: Fourteen thumbs in 13 patients (12 women) with a mean age of 64 years (range, 50 to 77 years) were available for assessment for a mean duration of 62 months (range, 41 to 97 months). The patients were evaluated subjectively and objectively. RESULTS: The modified LRTI procedure provided good pain relief, motion, strength, and stability without any severe complications related to the PL tendon harvesting. Radiography showed that compared to the preoperative status, the trapezial space decreased by about 40% at the final follow-up. CONCLUSIONS: The modified LRTI procedure provided significant subjective and objective improvements without severe complications particularly related to the harvesting of the PL tendon. This procedure is a valuable surgical option for trapeziometacarpal osteoarthritis and could be a useful salvage modality if the FCR tendon ruptures during the conventional LRTI procedure.

Reporte de caso: luxación simultánea carpometacarpiana del pulgar y los cuatro dedos / Case report: simultaneous carpometacarpal dislocation of the thumb and four fingers / Relato de caso: deslocamento carpometacarpal simultâneo do polegar e quatro dedos

Introducción: Las luxaciones carpo-metacarpianas son lesiones poco frecuentes, que van del 0.5 al 1% de las luxaciones de los huesos de la mano. Siendo extremadamente infrecuente la luxación simultanea de los 5 dedos. Objetivo: El objetivo de nuestro trabajo es documentar una lesión poco frecuente producida en un paciente asistido en nuestro centro. Así como realizar una puesta a punto sobre las medidas diagnósticas y terapéuticas de dicha lesión. Caso clínico: Se presenta el caso de un hombre de 63 años, diestro, artesano en hierro y madera, que sufre un accidente de tránsito de alta energía en moto versus auto, sufriendo traumatismo en mano derecha, sin presentar otros traumatismos. De la exploración física, en el departamento de emergencia, se constata la mano derecha dolorida con gran deformidad en dorso. Se diagnosticó: luxación dorsal carpo-metacarpiano de los 5 metacarpianos, con fractura del sector distal del trapecio, trapezoide, hueso grande y ganchoso. Se realizó reducción cerrada en block quirúrgico con anestesia general, siendo la reducción inestable se colocan agujas de Kirschner para su estabilización. Se confecciona, además, una férula de yeso de protección. Se solicitó una tomografía computada de control donde se objetiva buena reducción de las 5 articulaciones carpo-metacarpianas. Se retiraron las agujas de Kirschner a las 6 semanas. A los 3 meses de la lesión presenta una mano indolora, con buen rango de movilidad, con disminución a la fuerza prensil máxima comparada con la contralateral. El paciente reanuda sus tareas, incorporándose totalmente al trabajo a los 6 meses. Presenta, al año de la cirugía, un score de DASH excelente. Discusión: Las luxaciones de los 5 metacarpianos son lesiones extremadamente raras. Se han reportado en el mundo menos de 20 casos. A pesar de los elementos clínicos sugestivos, el diagnostico de esta lesión es difícil, siendo fundamental contar con un enfoque radiológico de perfil estricto de mano. Los resultados de esta lesión son inciertos, la función de la mano y la muñeca se mantiene pero frecuentemente asociado a una reducción de fuerza prensil. Este tipo de trauma lleva, en mayor o menor grado, al desarrollo de artrosis carpo metacarpiana a largo plazo.

Introduction: Carpometacarpal join dislocations, are really infrequent injuries, with an incidence that goes from 0,5 to 1% of all bone hand dislocations. Being extremely rare the simultaneous luxation of all five fingers. Objectives: Our work objective is to report a very infrequent injury found on a patient treated at our medical center. As well as getting up to date with diagnosis and treatment of such injury. Clinical case: A 63 year old male case is presented, right-handed, wood and iron artisan, who was involved in a high-impact car crush against a motorbike, suffering a trauma on his right hand, without any other injuries. At the emergency room, the physical examination showed a painful right hand deformed on the back. His diagnosis was dorsal carpometacarpal luxation of all 5 metacarpus, with a distal fracture of the trapezium, trapezoid, capitate and hamate bones. A closed reduction at the surgical room was performed, with general anesthesia, being the reduction unstable therefore Kirschner needles were used for stabilization. A plaster cast was used for its protection. A control tomography was performed showing good reduction of all 5 carpometacarpal joints. Kirschner needles were taken out 6 weeks later, at which point the rehabilitation program was started with the physiatrist team. Three months after the injury, the hand was painless, with a good range of movement, a diminished maximum catching strength compared with the other hand. The patient restarted his usual chores, fully reincorporating to his job 6 months later. He presents an excellent DASH score one year after surgery. Discussion: Luxation of all 5 metacarpus is an extremely rare injury. It has been reported less than 20 cases worldwide. In spite of clinical suggestive elements, the diagnosis of this injury is quite difficult, being of great importance to count with x-rays with a straight profile incidence of the hand. The results of this injury are uncertain; the functionality of the hand and wrist is frequently sustained associated with a reduction of the catching strength. This type of trauma will end up developing in greater or lesser degree, long term carpometacarpal arthrosis.

Introdução: As luxações carpo-metacarpianas são lesões raras, variando de 0,5 a 1% das luxações dos ossos da mão. O deslocamento simultâneo dos 5 dedos é extremamente incomum. Objetivo: O objetivo do nosso trabalho é documentar uma lesão rara produzida em um paciente assistido em nosso centro. Bem como realizar um set-up nas medidas diagnósticas e terapêuticas da referida lesão. Caso clínico: O caso de um homem de 63 anos, destro, artesão em ferro e madeira, que sofre um acidente de motocicleta de alta energia em uma motocicleta contra um carro, sofrendo traumatismo em sua mão direita, sem apresentar outras lesões, é apresentado. A partir do exame físico no pronto-socorro, há uma dor na mão direita com grande deformidade nas costas. Foi diagnosticado: luxação metacarpal do dorsal do carpo dos 5 metacarpos, com fratura do setor trapézio distal, trapézio, osso grande e hamato. Uma redução fechada foi realizada em um bloco cirúrgico com anestesia geral, com a redução instável sendo colocada com fios K para estabilização. Uma tala de gesso protetora também é feita. Solicitou-se tomografia computadorizada de controle, onde foi observada boa redução das 5 articulações carpo-metacarpianas. Os fios de Kirschner foram removidos às 6 semanas. Aos 3 meses após a lesão, ele apresenta uma mão indolor, com boa amplitude de mobilidade, com diminuição da força preênsil máxima em comparação com a força contralateral. O paciente retoma suas tarefas, ingressando totalmente no trabalho aos 6 meses. Um excelente escore DASH é apresentado um ano após a cirurgia. Discussão: As luxações dos 5 metacarpos são lesões extremamente raras. Menos de 20 casos foram relatados no mundo. Apesar dos elementos clínicos sugestivos, o diagnóstico dessa lesão é difícil, sendo fundamental a abordagem radiológica do perfil estrito da mão. Os resultados dessa lesão são incertos, a função da mão e do punho é mantida, mas freqüentemente associada a uma redução na força de preensão. Este tipo de trauma leva, em maior ou menor grau, ao desenvolvimento de artrose metacarpal do carpo a longo prazo.

Acute Dislocation of the Metacarpal-Trapezoid Joint

The trapezoid metacarpal dislocation is a rare event. In the literature, it is found in case reports. This injury is caused by direct or indirect high energy trauma. In most cases, the dislocation is dorsal and is difficult to reproduce because the joint is not very mobile. Given the low incidence and little evidence supported in the literature regarding the management, this injury can be treated by open or closed reduction; however, it has been published that most authors use Kirschner wire fixation with good results. Here we present our experience in the management of a male patient with acute trapezoid metacarpal dislocation handled with a splint with good functional results at 6 weeks.

Carpometacarpal Joint Fracture Dislocation of Second to Fifth Finger

BACKGROUND: Carpometacarpal joint fracture dislocation of the second to fifth finger is a rare hand injury associated with high energy trauma. Due to severe swelling and overlapping of bones on the radiograph of wrist-hand, dislocations are missed. We reported a series of six patients with rare carpometacarpal joint fracture dislocation treated with open reduction. METHODS: We retrospectively studied six cases of carpometacarpal joint fracture dislocation. All patients were treated with open reduction and internal fixation with Kirschner wire. Functional assessment was done with Quick Disabilities of the Arm, Shoulder and Hand score (Quick DASH score) at regular intervals. RESULTS: Average Quick DASH score was improved from 75.76 to 1.9 from 6 weeks to 18 months of duration. Of the six patients, three patients had a Quick DASH score of 0 at the end of 18 months. CONCLUSIONS: Careful hand examination and radiographic assessment is necessary to avoid missed diagnosis of carpometacarpal joint fracture dislocation. Early open reduction and internal fixation lead to excellent recovery of hand function.

Metacarpal Extension Osteotomy for Mild Thumb Carpometacarpal Arthritis: Retrospective Long-Term Outcomes / 대한정형외과학회잡지

PURPOSE: We report clinical and radiologic outcomes after metacarpal extension osteotomy for mild osteoarthritis of the thumb carpometacarpal joint. MATERIALS AND METHODS: From 1999 to 2008, 11 patients were diagnosed with mild thumb carpometacarpal arthritis (Eaton stage I, II), and extension osteotomies were performed. Of these, seven patients with at least 6 years follow-up were analyzed retrospectively. Male to female ratio was 2:5, and mean age at time of surgery was 38.9 years old. Symptom onset period was a mean of 11.2 months. Two patients were I, and five patients were II in Eaton stage. Preoperative visual analogue scale (VAS) and disabilities of the arm, shoulder and hand scale (DASH) scores were 3.7 points (3-4 points), and 40.1 points (32-51 points). Radial abduction was 38.5degrees (30degrees-45degrees), and volar abduction was 42.1degrees (40degrees-45degrees). Grip strengths and pinch powers, compared with the normal contralateral side were 82% (64%-90%) and 72% (40%-100%), respectively. RESULTS: The mean follow-up period was 8.5 years, and all patients except one maintained their occupational activity during the follow-up period. Final VAS and DASH scores were 0.7 points (0-2 points) and 11.7 points (8-16 points), respectively, and were statistically significant. Volar abduction, grip strengths, and pinch power were improved to 45degrees (40degrees-50degrees), 92.3% (73%-117%), and 94.4% (75%-117%) with statistical significances. In five patients, Eaton stages did not change, and two patients advanced to the next stage (stage I to II in one patient, stage II to III in one patient). CONCLUSION: Among the various treatment options for mild thumb carpometacarpal arthritis, metacarpal extension osteotomy may be considered as an effective treatment.

Ligament reconstruction tendon interposition arthroplasty for first carpometacarpal joint osteoarthritis / 中华骨科杂志

Objective To explore the clinical outcomes of Ligament reconstruction tendon interposition (LRTI) arthro-plasty for first carpometacarpal joint osteoarthritis. Methods From January 2008 to January 2011, 19 patients (21 thumbs) had surgery for thumb carpometacarpal arthritis using ligament reconstruction tendon interposition arthroplasty with flexor carpi radia-lis (FCR). There were 1 male and 18 were females with an average age of 60 years (range, 52-75 years);8 thumbs were on the left side and 13 thumbs on the right side. According to Eaton-Glickel classification, 1 thumb belonged to stageⅡ, 14 thumbs to stageⅢ, and 6 thumbs to stageⅣ. Pain level, grip strength, tip pinch strength, range of motion, and radiographic measurement were re-corded. According to the first metacarpal subsidence, the cases were classified in mild, moderate, and severe groups. Clinical out-comes of different group were evaluated and compared. Results All patients were followed up for 9-28 months with an average of 13.9 months. Comparision with the preoperative X-rays showed the first metacarpal had subsided 54.8% of the arthroplasty space after surgery. Grip strength improved from 18.6±10.1 kg to 20.5±11.9 kg, and tip pinch strength increased from 4.4±2.1 kg to 4.5 ± 1.9 kg after the surgery. Radial abduction increased from 55.7° ± 8.2° to 60.6° ± 7.2° and palmar abduction improved from 56.7° ± 8.5° to 63.5° ± 8.2° after the procedure. Patient pain levels (visual analogue scale, VAS) were significantly reduced, from 6.6 ± 1.4 to 0.5 ± 0.7. There was no difference of grip strength, tip pinch strength, thumbs range of motion, and VAS after LRTI in mild, moderate and severe groups. Conclusion LRTI resulted in excellent relief of pain and increase in range of motion. Howev-er, LRTI cannot sustain the arthroplasty space. Compared with the preoperative X-ray, the first metacarpal subsided more than 50%. Subsidence of the first metacarpal doesn't affect the pain relief, range of motion and strength improvement.
