ABSTRACT

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)

ABSTRACT

Introducción: Hay alteraciones óseas en las crestas alveolares que presentan un defecto volumétrico que dificultan la inserción de un implante dental en la posición tridimensionalmente correcta. Existen diferentes técnicas quirúrgicas de aumento óseo, entre ellas están los injertos en bloque o Split Bone Bloque Technique (SBBT). Esta técnica combina laminas corticales y hueso particulado de origen autólogo, logrando una integración más rápida del injerto. El objetivo de ese caso es describir el manejo y abordaje clínico de un defecto de alto compromiso estético y complicación quirúrgico-protésica mediante colgajo rotado de paladar, SBBT y posterior provisionalización de un implante dental osteointegrado. Caso clínico: Varón de 54 años que acude a la Clínica Universitaria de la Universidad Rey Juan Carlos con una dehiscencia del tejido blando que sobrepasaba la línea mucoginvival a nivel del incisivo 1.1 cursando con movilidad del fragmento vestibular El paciente no refería sintomatología ni signos patológicos. Se estableció como plan de tratamiento la extracción del diente y aumento del tejido blando mediante la técnica de colgajo rotado de paladar a pedículo posterior. Y posteriormente se realizó la regeneración ósea horizontal mediante SBBT. Conclusión: La regeneración ósea mediante SBBT es una técnica predecible con altas tasas de éxito tanto horizontal como vertical. Asociado a la regeneración, el manejo del tejido blando con colgajos o injertos de tejido conectivo permite obtener el volumen deseado. (AU)


Introduction: There are bone alterations in the alveolar crests that present a volumetric defect that makes inserting a dental implant in the correct threedimensional position difficult. There are different surgical techniques for bone augmentation, including block grafts or the Split Bone Block Technique (SBBT). This technique combines cortical laminas and particulate bone of autologous origin, thus achieving a faster integration of the graft. The aim of this case is to describe the management and clinical approach of a defect with high aesthetic compromise and surgical-prosthetic complication by means of a rotated palatal flap, SBBT and subsequent provisionalization of an osseointegrated dental implant. Case study: A 54 year old man attended the University Clinic of the Rey Juan Carlos University with a dehiscence of the soft tissue that went beyond the mucoginvival line at the level of incisor 1.1 with mobility of the vestibular fragment. The patient did not report any symptoms or pathological signs. Tooth removal and soft tissue augmentation using the rotated palatal to posterior pedicle flap technique were established as a treatment plan. Horizontal bone regeneration was then performed using SBBT. Conclusion: Bone regeneration using SBBT is a predictable technique with high success rates both horizontally and vertically. Associated with regeneration, soft tissue management with flaps or connective tissue grafts makes it possible to achieve the desired volume. (AU)

ABSTRACT

Resumen: La luxación glenohumeral recurrente suele asociarse a pérdida ósea de la porción glenoidea, siendo la localización anteroinferior la más afectada. El entendimiento de las estructuras relacionadas así como el uso de estudios de imagen actuales tales como la tomografía axial computarizada y la resonancia magnética han permitido avanzar respecto a la comprensión de la patología, asimismo el desarrollo de materiales quirúrgicos y herramientas de mínima invasión nos permiten continuar innovando respecto a los tratamientos previamente descritos, siendo posible intervenir en detalles técnicos con la intención de mejorar los resultados. Es por eso que hemos realizado lo descrito por Eden-Hybinette utilizando injerto tricortical cadavérico con tornillos canulados como método de fijación, limitando las comorbilidades asociadas a la toma de autoinjerto, dando como resultado un amplio beneficio para el paciente durante el procedimiento quirúrgico y en el período de recuperación.


Abstract: Recurrent glenohumeral dislocation is usually associated with bone loss of the glenoid portion, with the anteroinferior location being the most affected. The understanding of the related structures, as well as the use of current imaging studies such as computed axial tomography and magnetic resonance imaging, have made progress in understanding the pathology, as well as the development of surgical materials and minimally invasive tools, they allow us to continue innovating with respect to the previously described treatments, being possible to intervene in technical details with the intention of improving the results. That is why we have done what described by Eden-Hybinette, using tricortical cadaveric graft and as fixation method, limiting the comorbidities associated with the autograft taking, resulting a wide benefit for the patient, during the surgical procedure and in the recovery period.
