RESUMO

SUMMARY: At present, the anatomical relationship the mid-portion of popliteus tendon complex (PTC) and the surrounding tissues is still unclear, especially its relationship to the posterior cruciate ligament (PCL). It affected the anatomical reconstruction of the posterolateral complex (PLC) injury. A total of 30 cases of the adult human knee joint fixed with formalin were used. Sagittal sections were made in 14 knee joints by the P45 plastination technique and dissection of 16 cases of knee joints. The P45 section revealed that the popliteus muscle fascia ran superiorly over the posterior edge of the tibial intercondylar eminence, and turned forward to be integrated into the PCL. Laterally, near the posterior edge of the lateral tibial plateau, the popliteus tendon penetrates through the articular capsule (AC), where two dense fibrous bundles were given off upwards by the popliteus tendon: one was the ventral fiber bundle, which ran superiorly over the posterior edge of the tibial plateau and then moved forwards to connect with the lateral meniscus; the dorsal fibers bundle ascended directly and participated in the AC. Meanwhile, the popliteus muscle dissection showed that at the posterior edge of the platform of the lateral condyle of the tibia, at the tendon-muscle transition, the PTC and AC were anchored to PCL.


En la actualidad, la relación anatómica entre la porción media del complejo tendinoso poplíteo (CTP) y los tejidos circundantes aún no está clara, especialmente su relación con el ligamento cruzado posterior (LCP). Esto afecta la reconstrucción anatómica de la lesión del complejo posterolateral (LCP). Se utilizaron un total de 30 casos de articulaciones de rodillas humanas de individuos adultos fijadas con formalina. Se realizaron cortes sagitales en 14 articulaciones de rodilla mediante la técnica de plastinación P45 y disección de 16 casos de articulaciones de rodilla. La sección P45 reveló que la fascia del músculo poplíteo discurría superiormente sobre el margen posterior de la eminencia intercondílea tibial y giraba hacia delante para integrarse en el LCP. Lateralmente, cerca del margen posterior de la platillo tibial lateral, el tendón poplíteo penetra a través de la cápsula articular (CA), donde el tendón poplíteo desprendió hacia arriba dos haces fibrosos densos: uno era el haz de fibras ventral, que corría superiormente sobre el margen posterior de la meseta tibial y luego se movió hacia adelante para conectar con el menisco lateral; el haz de fibras dorsales ascendía directamente y participaba en la CA. Por su parte, la disección del músculo poplíteo mostró que en el margen posterior del platillo del cóndilo lateral de la tibia, en la transición tendón-músculo, el CTP y el AC estaban anclados al LCP.

RESUMO

Objective To compare the clinical results of surgical and conservative treatment of acute patellar dislocations.Methods Retrospective analyzed the clinical data of 35 patients with acute patellar dislocations from June 2004 to October 2009,and divided the patients into 2 groups.One group with 18 patients underwent surgical treatments,and the other group with 17 patients underwent conservative treatments,record the number of relapses cases of both the two groups.A radiographic examination was performed in the evaluation of the patients,and the Kujala questionnaire was applied with the intention of analyzing the improvement of pain and quality of life.Results All patients were followed up for more than 12 months.(1) The conservative treatment group exhibited a higher number of recurrent dislocations (7 patients) (41.2%) than the surgical treatment group,which did not have any relapses (x2 =9.265,P =0.002).(2) The patellar tilt returned to normal in the surgical group,while 8 patients returned to normal in the conservative group,with statistical difference between groups (x2 =10.980,P =0.001).And the lateral shift ratio returned to normal in the surgical group,while 6 patients returned to normal in the conservative group,with statistical difference between groups(x2 =7.667,P =0.006).(3)The surgical treatment group obtained a significantly better mean score on the Kujala test than preoperative ((90 ± 5) vs.(58 ± 6),t =16.465,P < 0.01) ; The conservative treatment group,compared with the preoperative,is not improved obviously ((72 ± 6) vs.(62 ± 8),t =0.943,P > 0.05) ;Postoperative group comparison,surgical group was higher than that in conservative group,there was significant difference between two groups (t =12.256,P < 0.01).Conclusion For acute patellar dislocation,surgical treatment can significantly restore patellar stability,improve the function of knee joint.

RESUMO

OBJETIVO Ä Avaliar a utilizaçäo de apenas um stent, owallstent (WS), no tratamento de lesöes longas (LL) ou múltiplas (LM). MÉTODOS Ä Trinta e oito pacientes com idades variando de 42Ä82 (m=66) anos, sendo por cento do sexo masculino. Os vasos tratados foram: descendente anterior (14 pacientes); coronária direita (12); circunflexa (9) e pontes de safena (4). Cinco pacientes necessitaram de 2 stents: 4 PalmazÄSchatz no segmento proximal do vaso e um que recebeu dois WS com diâmetro maior ou igual a 1,5mm do diâmetro nominal do vaso.Todos os pacientes necessitaram de hiperinsuflação após o implante do WS. RESULTADOS - O sucesso do implante foi de 95 por cento. Os dois casos de insucesso foram: um devido à fratura do sistema e outro à soltura incompleta. Ambos, submetidos à angioplastia convencional com sucesso. Não houve complicaçöes nesta série. CONCLUSÄO - O WS foi efetivo no tratamento de LL e LM com alto índice de sucesso imediato e sem complicaçöes.
