Inestabilidad cronica lateral del tobillo: comparacion entre la reparacion de brostrom-gould y una tecnica artroscopica / Chronic Lateral Ankle Instability: Comparison Between Brostrom-Gould Repair And An Arthroscopic Technique

Introducción La inestabilidad crónica lateral del tobillo es una patología frecuente en las personas que sufren esguinces. El tratamiento inicial es conservador y de no funcionar se recomienda el tratamiento quirúrgico; la técnica descrita por Broström y modificada por Gould es la más utilizada, efectiva y reportada en la actualidad. Con el advenimiento de la cirugía artroscópica, uno de los autores (JBGG) ha desarrollado una técnica mínimamente invasiva que se ha utilizado en la unidad de pie desde hace 8 años. Este trabajo evalúa los resultados funcionales, de dolor y cicatrización de los pacientes tratados con la técnica Artroscópica y la técnica de Broström-Gould abierta. Materiales & Métodos Se evaluaron un total de 111 pacientes, 50 con la técnica abierta y 61 con técnica artroscópica, operados por inestabilidad lateral crónica del tobillo entre enero de 2004 y diciembre de 2011. Se utilizo la escala AOFAS de tobillo y retropié para la medición del dolor, función y alineación, y la escala EVA para la medición del dolor. Resultados El promedio de puntuación final de la escala AOFAS fue de 90 puntos y la inestabilidad se revirtió en el 96% de los casos, para ambos grupo de pacientes. El dolor fue aliviado eficientemente por ambas técnicas. No se observaron diferencias estadísticamente significativas entre los grupos del estudio. Discusión La reparación artroscópica de la inestabilidad crónica lateral del tobillo fue tan efectiva para restablecer la función, estabilidad y eliminar el dolor del tobillo como la técnica abierta y puede tener una menor posibilidad de complicaciones relacionadas con las heridas.

Background Chronic lateral ankle instability is a common condition in people with inversion sprains. Initial treatment is conservative, and if that does not work a surgical approach is recommended, such as that described by Broström and later modified by Gould, and is the most used and effective. With the advent of arthroscopic surgery, one of the authors (JBGG) has recently developed a minimally invasive technique that has been used in the Surgical Foot and Ankle Unit of Imbanaco Medical Centre for 8 years. Therefore, this work aims to determine functional outcomes of patients treated with the arthroscopic technique compared with the open technique of Broström-Gould. Methods A total of 111 patients were evaluated, including 50 with the open method, and 61 with arthroscopic surgery technique for chronic lateral ankle instability between January 2004 and December 2011. The American orthopaedic foot and ankle score (AOFAS) scale for ankle and hindfoot was used for measuring pain, function, and alignment, and a visual analogue scale (VAS) was used to assess the pain. Results The final AOFAS score was 90 points, and instability was reversed in 96% of cases, for both groups of patients. The pain was relieved efficiently by both techniques. There were no statistically significant differences between the study groups. Discussion Arthroscopic repair of chronic lateral ankle instability is an effective tool to restore the function and stability, as well as eliminate ankle pain, and is comparable in effectiveness with the conventional technique. Additionally, there is a lower chance of complications related to wounds.

Principios biomecánicos en inestabilidad crónica posterolateral de rodilla / Biomechanical principles of chronic posterolateral knee instability

La inestabilidad crónica posterolateral de rodilla continúa siendo un tema desafiante desde la evaluación clínica hasta la resolución definitiva. La comprensión de la anatomía, biomecánica articular y las adaptaciones evolutivas de la rodilla para su complejo funcionamiento, son esenciales para el razonamiento diagnóstico y terapéutico de esas lesiones.

Chronic posterolateral knee instability continues to be a challenging issue from clinical evaluation to final resolution. The understanding of anatomy, joint biomechanics and evolutionary adaptations of the knee for its complex functioning are essential for the diagnostic and therapeutic reasoning of these injuries.

Razonamiento quirúrgico en inestabilidad crónica posterolateral de rodilla / Surgical rationale in chronic posterolateral knee injury

Los pacientes con mal alineamiento en varo pueden ser difíciles de tratar cuando tienen una lesión crónica de la esquina posterolateral (EPL), resultando en doble o triple varo y subsecuentemente varus thrust durante la marcha. Una osteotomía tibial alta es un procedimiento útil y necesario particularmente en el estadío crónico. Este artículo revisa los fundamentos de la planificación preoperatoria en una lesión crónica de la EPL.

Patients with varus malalignment can be difficult to manage when they have a chronic injury to the posterolateral corner (PLC), resulting in double or triple varus and subsequent varus thrust during gait. A high tibial osteotomy is a useful and necessary procedure particularly in the chronic setting. This article reviews the basics of preoperative planning in a chronic injury of the PLC.

Surgical treatment for chronic instability of the elbow / 中华创伤骨科杂志

Objective To study the cause and treatment of chronic instability of the elbow.Methods Between August 1998 and August 2002,12 patients with chronic instability of the elbow were treated in our de- partment:They underwent complete medical check-ups and imaging examinations.Surgical exploration was done to determine the causes of their conditions.Their radial and(or)ulnar collateral ligaments were repaired respectively or simultaneously through the medial and lateral approaches for all the patients.All the patients were followed up for two to six years,with an average of three years.Results The follow-ups revealed no recurrent dislocation of elbow in this group.The stress valgus test and lateral pivot shift test(PST)were negative for all the patients.No elbow pain occurred.The mean flexion and extension of elbow ranged from 0 to 135?.The mean pronation was 85?and mean supination 80?.According the evaluation system of Chinese Medical Association,eight cases were rated as excellent and four as fine,with the excellent and fine rate of 100%.Conclusions Lesions of radial and(or) ulnar collateral ligaments are the major cause for chronic instability of the elbow.Surgical reconstruction of the collateral ligaments can obtain good effects in treatment of recurrent dislocation of the elbow.
