Insertion torque is not a good predictor of pedicle screw loosening after spinal instrumentation: a prospective study in 8 patients [PDF]

, 2010
Background Pedicle screw loosening is a major safety concern in instrumented spinal surgery due to loosening with potential pseudarthrosis and possible loss of correction requiring revision surgery.

Medial Quadriceps Tendon‐Femoral Ligament Reconstruction Offers Favorable Clinical Outcomes and Low Complication Rates for Recurrent Patellar Instability: A Systematic Review

Arthroscopy, EarlyView.
Abstract Purpose To evaluate the surgical methods, clinical outcomes, and complication profile of patients undergoing medial quadriceps tendon‐femoral ligament reconstruction (MQTFLR), either isolated or as medial patellofemoral complex reconstruction (MPFCR), for recurrent patellar instability.

Comparison of pedicle screw loosening under uniaxial and multiaxial loading

Clinical Biomechanics
Pedicle screw loosening is a clinically-relevant failure mode following spinal fusion procedures, resulting from damage and compaction to the surrounding bone with loading of the bone-implant interface. Current in vitro tests for investigating pedicle screw loosening commonly apply uniaxial loading (e.g. screw pullout or toggle testing). However, these

Arthroscopic Continuous Anterior Cruciate Ligament‐Medial Collateral Ligament Reconstruction Using a Single Rectus Femoris Autograft With Posterior Oblique Ligament Reconstruction: A Technical Note

Arthroscopy Techniques, EarlyView.
Abstract Multiligament knee injuries are challenging to manage and often require harvesting multiple grafts. Rectus femoris tendon autograft provides predictable length and diameter, making it a promising option for anterior cruciate ligament (ACL) reconstruction and combined procedures. In this technical note, we describe an arthroscopic technique for

Anterior Cruciate Ligament Reconstruction With Preservation of the Tibial Insertion of the Hamstring Tendons and Double‐Pulley Technique

Arthroscopy Techniques, EarlyView.
Abstract Anterior cruciate ligament (ACL) injury is one of the most common knee disorders, occurring mostly in sports‐related injuries. After injury, knee stability is compromised, leading to further damage to surrounding structures, such as meniscal tears, cartilage wear, and other lesions.

Effects of smoking on pedicle screw–based dynamic stabilization: radiological and clinical evaluations of screw loosening in 306 patients [PDF]

Journal of Neurosurgery: Spine, 2020
OBJECTIVECigarette smoking has been known to increase the risk of pseudarthrosis in spinal fusion. However, there is a paucity of data on the effects of smoking in dynamic stabilization following lumbar spine surgery. This study aimed to investigate the clinical outcomes and the incidence of screw loosening among patients who smoked.METHODSConsecutive ...

The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

Clinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.
