OBJECTIVE To anatomically evaluate the femoral origin and tibial insertion of the anteromedial and posterolateral bands of the anterior cruciate ligament. METHODS We studied eight cadaver knees as for the following: in the femur, distance from the center of the anteromedial band to the deep cartilage and the ceiling; also in the femur, distance from the center of the posterolateral band to th...

This retrospective study investigated the early results of a single-stage posterolateral transpedicular corpectomy and fusion in the thoracolumbar spine. A modified technique with nerve preservation and bilateral expandable cage implantation is described. Four patients with vertebral metastasis and one patient with vertebral osteomyelitis were included in this series. Two patients underwent two...

The management of multiligament knee injury is a complex process starting with the adequate identification of the injury. A detailed physical and radiographic examination with a thorough understanding of knee anatomy is crucial to assess all damaged structures: anterior cruciate ligament, posterior cruciate ligament, posteromedial corner including the medial collateral ligament, and posterolate...

This retrospective study was undertaken to compare the outcomes of staged bilateral total hip arthroplasty (THA) by the conventional approach with those of two-incision minimally invasive (MIS-2) THA in terms of clinical and radiological results, complications, and patient preferences. Twenty-two patients aged 30 to 80 years underwent staged bilateral THA. The conventional posterolateral approa...

BACKGROUND Currently, one third of patients treated with cardiac resynchronization therapy (CRT) do not respond. Nonresponse to CRT may be explained by the presence of scar tissue in the posterolateral left ventricular (LV) segments, which may result in ineffective LV pacing and inadequate LV resynchronization. In the present study, the relationship between transmural posterolateral scar tissue...

To determine whether untreated grade 3 posterolateral knee injuries contribute to a significant increase in force on a posterior cruciate ligament reconstruction graft, we measured the force on the graft during joint loading of a posterior cruciate ligament-reconstructed knee with otherwise intact structures and then selectively cut the popliteofibular ligament, popliteus tendon, and the fibula...

This study was conducted to identify the risk of avascular necrosis of the femoral head after arthroscopic femoroplasty extending to the posterolateral femoral neck, the source of the primary blood supply to the femoral head. Cam lesions of femoroacetabular impingement are typically anterior along the junction of the femoral head and neck. However, anatomic variations can involve the posterolat...
