In the past decade, thoracic endovascular aortic repair (TEVAR) has become the primary treatment option in descending aneurysm and dissection. The clinical outcome of this minimally invasive technique is strictly related to an appropriate patient/stent graft selection, hemodynamic interactions, and operator skills. In this context, a quantitative assessment of the biomechanical stress induced i...

Outcomes after posterior cruciate ligament (PCL) reconstructive surgery have historically been inferior to outcomes after reconstruction of the anterior cruciate ligament (ACL). As such, some surgeons may be reluctant to recommend reconstruction of the PCL. However, recent technologic advances have substantially improved PCL reconstructive surgical outcomes. These advances include better unders...

Successful posterior cruciate ligament (PCL) reconstruction is challenging because of the complex structures and difficult reconstruction techniques that are required. The reported results have been inconsistent. Variables that affect the results of surgery to restore PCL function include combined associated ligaments injury, difficulty to duplicate PCL anatomy, wide variation in broad femoral ...

The fixation of soft tissue grafts used in anterior cruciate ligament reconstruction (ACL) is a determining factor for the long-term success of the ACL reconstruction. This article provides an overview of the mechanical test methods used in our laboratory and the biomechanics literature to compare methods of soft tissue fixation that are available to the practicing orthopaedic surgeon. The basi...

INTRODUCTION: Despite the recent advances in our understanding of the anatomy and biomechanics of the posterior cruciate ligament (PCL), current methods of PCL reconstruction continue to lack the clinical success that anterior cruciate ligament (ACL) reconstruction has experienced, with many patients developing residual posterior laxity following surgery [1]. One variable that directly affects ...

BACKGROUND Recently, many studies have emphasized the importance of the comprehension of detailed functional anatomy and biomechanics of the elbow and its significant contribution in facilitating good functional outcomes of conservative and surgical treatment in the field of elbow disorders. METHODS The most common disease of elbow disorders and their treatment was reviewed. RESULTS Lateral...

Background: As the main translational and rotatory stabilizer of knee, anterior cruciate ligament (ACL) plays a critical role in knee biomechanics. Anterior ruptures generally require surgical attention for not only restoration stability but also prevention meniscal chondral injuries. There are countless options both surgeon patient when contemplating graft choice technique ACL reconstruction. ...

PURPOSE To assess the remodelling process of the bone graft and fused bodies after non-instrumented anterior interbody fusion with autogenous iliac graft in patients with spondylosis, infections, fractures, or disorders of the cervical spine. METHODS 68 patients aged 18 to 58 years who underwent non-plated anterior lower cervical interbody fusion with an iliac graft were retrospectively studi...

Arthroscopic over-resection of the head-neck junction during the treatment of a cam deformity can be a devastating complication and is difficult to treat. Large defects of the femoral head-neck junction (FHNJ) increase the risk of femoral neck fracture and can also affect hip biomechanics. We describe a case of an iatrogenic defect of the FHNJ due to excessive bone resection, and a previously n...

BACKGROUND Labral reconstruction using iliotibial band (ITB) autografts and semitendinosus (Semi-T) allografts has recently been described in cases of labral deficiency. PURPOSE/HYPOTHESIS To characterize the joint biomechanics with a labrum-intact, labrum-deficient, and labrum-reconstructed acetabulum in a hip cadaveric model. The hypothesis was that labral resection would decrease contact a...
