Fijación artroscópica sin metal del bloque óseo en la inestabilidad anterior del hombro. Resultados funcionales y radiológicos a corto plazo / Arthroscopic bone block metal-free fixation for anterior shoulder instability. Short-term functional and radiological outcomes

Introducción: Existen múltiples técnicas para la reconstrucción del defecto óseo glenoideo con bloque óseo en la inestabilidad glenohumeral anterior que reducen el riesgo de recidiva tras cirugía de partes blandas, la mayoría utilizando fijación metálica. El objetivo de este estudio es evaluar la seguridad quirúrgica y los resultados funcionales y radiológicos a corto plazo de los pacientes sometidos a una técnica artroscópica con bloque óseo y fijación sin metal. Material y métodos: Estudio retrospectivo de pacientes con inestabilidad y defecto óseo glenoideo>15% con 12 meses de seguimiento mínimo. Se sometieron a estudio radiográfico y tomografía axial computarizada. Se cumplimentaron escalas funcionales de manera pre y postoperatoria: el Western Ontario Shoulder Instability Index y la escala de Rowe. Resultados: Se incluyeron un total de 21 pacientes con una edad media de 30,6 (DE 7,1). Todos mostraron consolidación radiográfica a los 3 meses. El 90,4% de los injertos presentó osteólisis en las áreas más periféricas y el 95,2% presentó consolidación en las áreas de contacto con la glenoides. La media del área de superficie de la glenoides pasó del 79,3% preoperatoria al 98,4% a los 12 meses. Los resultados funcionales medios resultaron estadísticamente significativos (p<0,001) tanto para el Western Ontario Shoulder Instability Index (de 35,6 a 86,9) como para la escala de Rowe (de 25,2 a 96,4). No se presentaron complicaciones graves. Conclusión: La técnica de bloque óseo y fijación sin metal es un método de fijación seguro, sin componentes metálicos. Consigue una consolidación completa del injerto con buenos resultados funcionales y radiográficos a los 12 meses.(AU)

Introduction: Anterior glenohumeral bone loss reconstruction reduces failure rates after soft tissue surgery in patients with large glenoid bone defects. Multiple bone block techniques have been described, most with metal hardware fixation. The objective of this study is to evaluate the safety, as well as the short-term functional and radiological results of an arthroscopic bone block metal-free fixation or bone block cerclage. Material and methods: Retrospective study of patients with glenohumeral instability and>15% glenoid bone loss operated during 2019 with follow-up of at least 12 months. Radiography and computerized tomography studies were performed. Functional outcomes were evaluated before and after surgery with the Western Ontario Shoulder Instability Index and Rowe score. Results: A total of 21 patients with a median age of 30.6 (SD 7.1) were included. All showed radiographic consolidation at 3 months follow-up. A percentage of 90.4 of bone grafts presented osteolysis at peripherical areas and 95.2% revealed consolidation in the areas with contact to the glenoid. The median glenoid estimated surface went from 79.3% before surgery to 98.4% at 12 months. Functional scores were statically significant (P<.001) for Western Ontario Shoulder Instability Index (35.6-86.9) and Rowe score (25.2 to 96.4). No serious complications were reported. Conclusion: The bone block cerclage is a safe, metal-free technique that achieves total consolidation of the bone graft and favorable functional and radiological outcomes at 12 months follow-up.(AU)

Enfermedades reumatológicas en la columna vertebral: diagnóstico radiológico / Rheumatic diseases of the spine: imaging diagnosis

La afectación raquídea es frecuente tanto en las espondiloartritis como en la artritis reumatoide, la cual afecta selectivamente al segmento cervical. La afectación reumatoide de la columna cervical presenta unas manifestaciones radiológicas típicas, fundamentalmente en forma de varios tipos de patrones de inestabilidad articular atloaxoidea. La resonancia magnética (RM) es la técnica de elección para evaluar la posible repercusión mielorradicular de la inestabilidad atloaxoidea en los pacientes con artritis reumatoide, así como para evaluar parámetros indicativos de inflamación activa, como el edema óseo y la sinovitis. La afectación axial es característica en las espondiloartritis y presenta unas manifestaciones radiográficas distintivas, que reflejan fenómenos destructivos y reparativos. El uso de la RM ha cambiado la concepción de la espondiloartritis al conseguir detectar de manera directa los cambios inflamatorios propios de la enfermedad, permitiendo establecer un diagnóstico precoz cuando las radiografías son normales (espondiloartritis axial no radiográfica), evaluar el pronóstico de la enfermedad y contribuir a la planificación del tratamiento (AU)

Spinal involvement is common both in the spondyloarthritides and in rheumatoid arthritis, in which the cervical segment is selectively affected. Rheumatoid involvement of the cervical spine has characteristic radiologic manifestations, fundamentally different patterns of atlantoaxial instability. Magnetic resonance imaging (MRI) is the technique of choice for evaluating the possible repercussions of atlantoaxial instability on the spinal cord and/or nerve roots in patients with rheumatoid arthritis as well as for evaluating parameters indicative of active inflammation, such as bone edema and synovitis. Axial involvement is characteristic in the spondyloarthritides and has distinctive manifestations on plain-film X-rays, which reflect destructive and reparative phenomena. The use of MRI has changed the conception of spondyloarthritis because it is able to directly detect the inflammatory changes that form part of the disease, making it possible to establish the diagnosis early in the disease process, when plain-film X-ray findings are normal (non-radiographic axial spondyloarthritis), to assess the prognosis of the disease, and to contribute to treatment planning (AU)
