The Hook Test Is Not Pathognomonic for Foveal Detachment of the Triangular Fibrocartilage.

Background The integrity of the foveal insertion of the triangular fibrocartilage complex (TFCC) is currently assessed by inference using the hook test. Using dry arthroscopic techniques, the primary author observed that many patients with painful distal radioulnar joint (DRUJ) instability and a positive hook test had an intact foveal insertion. This study was performed to determine whether a positive hook test is a reliable index of a tear of the foveal insertion. Technique The hook test is performed using a probe to elevate the TFCC off the ulna head toward the articular surface of the lunate. In this study, the hook test was considered positive if the TFCC could be elevated to bridge more than 80% of the space between the TFCC and the articular surface of the lunate. Patients and Methods A retrospective study was performed using the medical records and arthroscopic videos of 113 patients who had clinical signs of DRUJ instability and underwent arthroscopic surgery performed by the primary author in 2020. It was documented whether the hook test was positive or negative, whether the foveal insertion was intact, abnormal or absent, and whether there were peripheral (dorsal or volar) tears of the TFCC. Sensitivity and specificity were calculated using arthroscopic findings as the reference standard. Results The sensitivity of the hook test was found to be 100%, and the specificity was 7.0%. The positive predictive value for foveal pathology was found to be 12.3% and the negative predictive value 100%. The diagnostic accuracy of the hook test in determining the presence of foveal tears was found to be 17.7%. The diagnostic accuracy of the hook test in determining the presence of a TFCC abnormality was 99.1%. Conclusions A positive hook test is indicative of a tear of the TFCC, but it is not anatomically specific for a tear of the foveal insertion. To reliably assess the foveal insertion, it must be visualized and probed using dry arthroscopic techniques.

Prevention and management of respiratory disease in young people with cerebral palsy: consensus statement.

Respiratory illness is the leading cause of mortality in children with cerebral palsy (CP). Although risk factors for developing chronic respiratory illness have been identified, comprehensive clinical care recommendations for the prevention and management of respiratory illness do not currently exist. We invited over 200 clinicians and researchers from multiple disciplines with expertise in the management of respiratory illness in children with CP to develop care recommendations using a modified Delphi method on the basis of the RAND Corporation-University of California Los Angeles Appropriateness Method. These recommendations are intended for use by the wide range of practitioners who care for individuals living with CP. They provide a framework for recognizing multifactorial primary and secondary potentially modifiable risk factors and for providing coordinated multidisciplinary care. We describe the methods used to generate the consensus recommendations, and the overall perspective on assessment, prevention, and treatment of respiratory illness in children with CP. WHAT THIS PAPER ADDS: The first consensus statement for preventing and managing respiratory disease in cerebral palsy (CP). Risk factors for respiratory disease in CP should be identified early. Individuals with CP at risk of respiratory disease require regular assessment of risk factors. Effective partnerships between multidisciplinary teams, individuals with CP, and families are essential. Treatment of respiratory disease in individuals with CP must be proactive.

La enfermedad respiratoria es la principal causa de mortalidad en niños con parálisis cerebral (PC). Aunque se han identificado los factores de riesgo para desarrollar enfermedades respiratorias crónicas, actualmente no existen recomendaciones completas de atención clínica para la prevención y el tratamiento de las enfermedades respiratorias. Invitamos a más de 200 médicos e investigadores de múltiples disciplinas con experiencia en el manejo de enfermedades respiratorias en niños con PC para desarrollar recomendaciones de atención utilizando un método Delphi modificado sobre la base del Método de adecuación RAND Corporation - Universidad de California en Los Ángeles. Estas recomendaciones están destinadas a ser utilizadas por la amplia gama de profesionales que atienden a personas que viven con PC. Proporcionan un marco para reconocer factores de riesgo multifactoriales primarios y secundarios potencialmente modificables y para proporcionar atención coordinada multidisciplinaria. Describimos los métodos utilizados para generar las recomendaciones de consenso, y la perspectiva general sobre la evaluación, prevención y tratamiento de enfermedades respiratorias de niños con PC.

Doença respiratória é a principal causa de mortalidade em crianças com paralisia cerebral (PC). Embora fatores de risco para desenvolver doença respiratória crônica tenham sido identificados, recomendações abrangentes de cuidado clínico e gerenciamento de doença respiratória não existem atualmente. Convidamos cerca de 200 clínicos e pesquisadores de múltiplas disciplinas com experiência no manejo de doença respiratória em crianças com PC para desenvolver recomendações de cuidado usando um método Delphi com base no método de Apropriação da Corporação RAND - Universidade da Califórnia. Estas recomendações são para uso de profissionais que atendem indivíduos com PC. Elas oferecem uma estrutura para reconhecer fatores de risco multifatoriais potencialmente modificáveis e prover cuidado multidisciplinar. Descrevemos métodos usados para gerar as recomendações do consenso, e a perspectiva geral de avaliação, prevenção e tratamento de doença respiratória em crianças com PC.

Outcome of primary tendon grafts for open Zone 3 extensor tendon injuries.

Open injuries of the extensor mechanism in Zone 3 (dorsum of the proximal interphalangeal joint) have poor outcomes. We retrospectively analysed the outcomes of treating 19 Zone 3 extensor tendon injuries in 17 patients. The treatment comprised wound excision and debridement, primary tendon graft to reconstruct the damaged/missing extensor tendon, skeletal fixation when required, local flaps to vascularize the zone of injury and immediate short arc motion therapy. Using the criteria defined by Geldmacher et al., the outcome was predicted to be poor in nine, satisfactory in seven and good in three cases. In this study the outcomes were excellent in 10, good in six and satisfactory in three cases. Mean range of motion was 75° (range 25°-115°) at the proximal interphalangeal joint. We conclude that using the protocol described there should no longer be the perception of a dismal outcome for these complex Zone 3 extensor tendon injuries.Level of evidence: IV.
