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

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.

A simplified extrapedicular workflow for cement-augmented cannulated pedicle screw fixation in osteoporotic vertebral collapse: a technical note

Interdisciplinary Neurosurgery
Pedicle screw fixation in osteoporotic vertebrae remains challenging because of poor bone quality and limited screw purchase. Cement-augmented cannulated pedicle screws are widely used to improve fixation strength; however, the optimal workflow for screw
