Perioperative Management for Patients With Spinal Muscular Atrophy Undergoing Scoliosis Surgery: A Single‐Center Retrospective Study

Orthopaedic Surgery, Volume 18, Issue 7, Page 1328-1341, July 2026.
This largest Asian case series confirms that posterior spinal fusion for SMA scoliosis is safe and effective despite severe deformity and markedly impaired pulmonary function. Meticulous multidisciplinary care, including advanced airway planning, hemodynamic support, blood management, and proactive electrolyte correction, is critical to optimizing ...

Safety of Pedicle Screws in Adolescent Idiopathic Scoliosis Surgery [PDF]

, 2017
To review existing publications on the safety of pedicle screw insertions in adolescent idiopathic scoliosis (AIS). Despite having increased risk for neurological and visceral injuries, the use of pedicle screws have led to increased correction rates in ...

Autonomous Frameless Spine Registration and Robot‐Assisted Surgery

Orthopaedic Surgery, Volume 18, Issue 7, Page 1471-1490, July 2026.
Workflow of a contactless, frame‐free, robot‐assisted vertebra registration system. Preoperative CT data establish vertebra {V} and mask {Mpre} coordinate systems. Their relationship is computed, and intraoperatively the robot recognizes the skin‐affixed mask, defining {Mintra}.

Pedicle instrumentation in the thoracic spine. A morphometric and cadaveric study for placement of screws. [PDF]

, 1999
Study Design. In part 1 of the study, the morphometry of thoracic pedicles and bony landmarks for pedicle screw placement were evaluated. In part 2, pedicle screws were inserted in fresh cadavers, using a different entry point in the left and right ...

Effect of pedicle screw augmentation with a self-curing elastomeric material under cranio-caudal cyclic loading—a cadaveric biomechanical study

Journal of Orthopaedic Surgery and Research, 2018
Background Pedicle screws can be augmented with polymethylmethacrylate (PMMA) cement through cannulated and fenestrated pedicle screws to improve screw anchorage. To overcome the drawbacks of PMMA, a modified augmentation technique applying a self-curing

A Modified Technique of Minimally Invasive Cortical Bone Trajectory Screws With U‐Rod for Treatment of Lumbar Spondylolysis

Orthopaedic Surgery, Volume 18, Issue 7, Page 1498-1507, July 2026.
The U‐rod technique combined with cortical bone trajectory screws is a safe and effective method for the treatment of lumbar spondylolysis. ABSTRACT Objective Spondylolysis is a common cause of low back pain, especially in the young athletic population. It involves a defect, either unilateral or bilateral, of the pars interarticularis.

Pedicle screw pull-out strength between the Jamshidi needle and pedicle probe techniques in an osteoporotic cancellous bone model: a biomechanical study [PDF]

Introduction: Spinal fusion surgery with pedicle screws is commonly performed to stabilize the spine of osteoporotic patients. However, securing a strong screw fixation in osteoporotic bone presents significant challenges due to the reduced bone density.

The Anterolateral Transpedicular Transverse Process Screw Technique: Surgical Techniques, Biomechanical study and Preliminary Outcomes

Orthopaedic Surgery, Volume 18, Issue 7, Page 1375-1397, July 2026.
This study designed a novel anterolateral screw placement technique and, based on this, developed a new anterolateral fixation method. Imaging, biomechanical, and short‐term efficacy analyses revealed that the Anterolateral Transpedicular Transverse Process Screw (ALTTS) technique achieves a high success rate for L5 vertebral fixation (pedicle width ...
