[Complex multiligament knee injury associated with patellar tendon rupture]. / Lesiones multiligamentarias de rodilla asociadas a ruptura de tendón rotuliano.

INTRODUCTION: Multi-ligament injury of the knee joint is defined as damage to two or more major ligaments. They are uncommon, with an incidence of ? 10:10,000. They constitute less than 0.02% of all orthopedic lesions. It is even less frequent to find an association of these with a complete rupture of the patellar tendon which presents with a prevalence of 2.4%. CASE REPORT: 22 year old male; he presented a high-speed accident with a diagnosis of multi-ligament left knee injury stage V of Schenck associated with complete patellar tendon rupture treated in a single surgical time with ligament reconstruction, four weeks after traumatic event. A score of 88.5 was obtained after eight months with the IKDC 2000 form for the subjective functional evaluation of the knee. DISCUSSION: The definitive surgical treatment is performed four weeks after the injury. This reduces the risk of instability. In our clinical case, the patient is integrated into the activities of his daily life after eight months. To validate this technique as effective or good for its use, a greater number of patients treated in the same way is required. It is, however, suggested to contemplate as a management option. CONCLUSION: These types of lesions are infrequent with a prognosis reserved.

INTRODUCCIÓN: La lesión multiligamentaria de la articulación de rodilla se define como el daño a dos o más ligamentos principales. Estas lesiones son poco comunes, con una incidencia de ? 10:10,000. Constituyen menos de 0.02% de todas las lesiones ortopédicas. Es aún menos frecuente encontrar asociación de éstas a una ruptura completa del tendón patelar, la cual se presenta con una prevalencia 2.4%. CASO CLÍNICO: Masculino de 22 años sufrió accidente de alta velocidad, con diagnóstico de lesión multiligamentaria de rodilla izquierda estadio V de Schenck asociada a ruptura completa de tendón patelar, fue tratado en un solo tiempo quirúrgico con reconstrucción ligamentaria cuatro semanas después de evento traumático. Se obtuvo a los ocho meses un puntaje de 88.5 con el formulario IKDC 2000 para la evaluación funcional subjetiva de la rodilla. DISCUSIÓN: El tratamiento quirúrgico definitivo se realiza a las cuatro semanas de la lesión. Con esto se disminuye el riesgo de inestabilidad. En nuestro caso clínico el paciente se logra integrar a las actividades de su vida diaria después de ocho meses. Para validar esta técnica como efectiva o buena para su uso, se requiere un mayor número de pacientes tratados de la misma forma. Sin embargo, se sugiere contemplar como una opción de manejo. CONCLUSIÓN: Lesión poco frecuente, de tratamiento quirúrgico con un pronóstico reservado.

[Lumbar herniated disks treated with a dynamic interspacer]. / Hernias discales lumbares tratadas con interespaciador dinámico.

UNLABELLED: Lumbar herniated disks result in lumbar pain with neurologic involvement. Medical treatment and rehabilitation provide improvement for this type of lumbar pain at the early stages. When conservative treatment fails, the surgical option offers the possibility of improving patients' health status. Moojen considers that the application of interspinous spacers provides good results. The purpose of this research is to assess the clinical and imaging results in patients with contained lumbar herniated disk treated with the DYNAMIC INTERSPACER interspinous spacer, a Mexican product. MATERIAL AND METHODS: The efficacy of the interspinous device was assessed by means of a near-investigational and longitudinal study conducted at "General Ignacio Zaragoza" ISSSTE Regional Hospital in patients with a diagnosis of lumbar pain. RESULTS: The mean age of the sample is 46.1 years, with an age range of 26-55 years. The treated levels were 6 L5-S1 and 5 L4-L5; two levels were treated in two patients. The mean preoperative VAS score was 8.1. The mean VAS score at postoperative year three was 1.6. CONCLUSION: Multiple types and brands of foreign interspinous devices are applied in Mexico which results in patients' clinical improvement. We proved that the use of the Mexican interspinous device can clinically improve patients with lumbar pain due to herniated disk. A decrease in the compression of the sac or the nerve roots by the hernia was observed in the comparative preoperative and postoperative MRI images.
