Introduction: Surgical treatment of thoracolumbar fracture without neurological damage has resulted in better clinical and radiological outcome than conservative treatment. Traditional open approach is associated with extensive paravertebral muscle postoperative morbidity so percutaneous pedicle screw fixation highly valuable alternatives.
 Aims: to evaluate the efficacy traumatic deficit....

Generally, bilateral pedicle screw fixation after Minimal Invasive (MIS) TLIF is accepted as a standard procedure for treating symptomatic spinal pathologies, such as degenerative spinal stenosis, spondylolisthesis, recurrent disc herniation, postlaminectomy instability, and deformity (10). Some authors have recently demonstrated that unilateral pedicle screw fixation is as effective for spinal...

BACKGROUND The use of an interference fit wedged bone plug to provide fixation in the tibial tunnel when using bone-patellar tendon-bone autograft for anterior cruciate ligament reconstruction offers many theoretic advantages including the potential to offer a more economical and biological alternative to screw fixation. This technique has not been subjected to biomechanical testing. We hypothe...

Recently it has been shown that anatomic tibial graft fixation in anterior cruciate ligament (ACL) reconstruction is preferable in order to increase isometry and knee stability. To facilitate anatomic patellar tendon graft fixation, customized graft length shortening is necessary. The purpose of this study was to compare the initial fixation strength of four different shortened patellar tendon ...
