Osteonecrosis is a terrible condition that can cause advanced arthritis in a number of joints, including the knee. The three types of osteonecrosis that can affect the knee are secondary, post-arthroscopic, and spontaneous osteonecrosis of the knee (SPONK). Regardless of osteonecrosis classification, treatment for this condition seeks to prevent further development or postpone the onset of knee end-stage arthritis. Joint arthroplasty is the best course of action whenever there is significant joint surface collapse or there are signs of degenerative arthritis. The non-operative options for treatment at the moment include observation, nonsteroidal anti-inflammatory medications (NSAIDs), protective weight bearing, and analgesia if needed. Depending on the severity and type of the condition, operational procedures may include unilateral knee arthroplasty (UKA), total knee arthroplasty (TKA), or joint preservation surgery. Joint preservation techniques, such as arthroscopy, core decompression, osteochondral autograft, and bone grafting, are frequently used in precollapse and some postcollapse lesions, when the articular cartilage is typically unaffected and only the underlying subchondral bone is affected. In contrast, operations that try to save the joint following significant subchondral collapse are rarely successful and joint replacement is required to ease discomfort. This article’s goal is to summarise the most recent research on evaluations, clinical examinations, imaging and various therapeutic strategies for osteonecrosis of the knee, including lesion surveillance, medicines, joint preservation methods, and total joint arthroplasty.
<p><strong>Objetivo: </strong>Describir y analizar una técnica de osteosíntesis palmar de radio distal con preservación del pronador cuadrado.</p><p><strong>Materiales y Métodos: </strong>Se revisaron, en forma retrospectiva, 24 pacientes operados con esta técnica (16 mujeres y 8 hombres; edad promedio 65 años). Doce fracturas eran de tipo A; 7, de tipo B y 5, de tipo C. La técnica quirúrgica consiste en practicar una incisión cutánea de 25 mm y profundizar hasta observar el pronador cuadrado. Sin seccionarlo, se realiza una disección de su borde distal, a fin de introducir la placa bloqueada volar por debajo del músculo. Se colocan los tornillos distales bajo visión directa y los tornillos proximales, en forma percutánea. La evaluación posoperatoria se llevó a cabo mediante análisis clínico-funcional y radiográfico.<strong></strong></p><p><strong>Resultados: </strong>En el último control, todos los pacientes presentaban signos clínicos y radiográficos de consolidación ósea. El puntaje en la escala DASH fue, en promedio, de 4,8. Se observó una inclinación palmar posoperatoria de la superficie articular del radio de 14,3º promedio y una inclinación radial de 26,3º promedio. No se detectaron complicaciones relacionadas con la fractura, el implante o la herida quirúrgica en ninguno de los controles posoperatorios.</p><p><strong>Conclusiones: </strong>Sin bien no existe bibliografía que demuestre que la técnica mininvasiva sea superior, sostenemos que el hecho de obtener resultados similares con ambos abordajes (mininvasivo y convencional) justifica llevar a cabo esta técnica con preservación del pronador cuadrado, sobre todo en los pacientes preocupados por el aspecto cosmético de la cicatriz.</p>
Aims Our objective is to compare the functional results in patients that underwent surgery for recurrent anterior shoulder instability (RAGHI) during the COVID-19 pandemic with remotely-based rehabilitation, to those who had surgery before the pandemic and had in-person rehabilitation therapy. Methods A retrospective case series of 68 patients were included and divided into two groups: In person-group and Home-based group. Western Ontario Shoulder Instability Index (WOSI) and Subjective Shoulder Value (SSV) scores were used to evaluate objective and subjective clinical parameters. Time and level of return to sports was studied by the Subjective Patient Outcome for Return to Sports (SPORTS) score. Results The mean SSV score was 82% (40–100) on the In-Person group compared with 87% (65–100) for the Home-Based group. Results for WOSI score were similar, with an average of 210.42 (90%) for In-Person and 261.45 (88%) for the Home-Based group ( p 0.12). Return to sports was carried out in an average of 6.6 (4–16) months for In-Person group, compared to 6.5 (5–8) months for Home-Based. Conclusion Follow-up and rehabilitation methods for patients who underwent surgery for RAGHI, during COVID-19 lockdown, were not significantly ( p 0.12) affected on functional and athletic return in comparison to traditional methods according to WOSI scale. Level of evidence IV Retrospective series of cases
Introducción: Pocos cuestionarios para cuantificar y categorizar las limitaciones funcionales subjetivas y objetivas en la patología de hombro han sido traducidos al español de la Argentina. Objetivo: Realizar la estandarización, traducción y adaptación transcultural del Constant-Murley Score al español de la Argentina. Materiales y Métodos: La adaptación cultural se realizó siguiendo las etapas propuestas en la guía de la International Society of Pharmacoeconomic and Outcomes Research que establece las directrices para la traducción y adaptación cultural de medidas reportadas por los pacientes. Resultados: La versión traducida al español fue evaluada mediante entrevistas cognitivas en dos etapas. Posteriormente se reformularon preguntas para el mejor entendimiento de los elementos y sus opciones de respuesta y, dentro de cada apartado, se realizaron modificaciones específicas. Conclusión: Se logró realizar la traducción y adaptación transcultural del Constant-Murley Score, con lo que se obtuvo una herramienta para aplicar en la población argentina con patologías de hombro.
