Artificial Intelligence for Bone: Theory, Methods, and Applications

Advanced Intelligent Discovery, EarlyView.
Advances in artificial intelligence (AI) offer the potential to improve bone research. The current review explores the contributions of AI to pathological study, biomarker discovery, drug design, and clinical diagnosis and prognosis of bone diseases. We envision that AI‐driven methodologies will enable identifying novel targets for drugs discovery. The

A Biomechanical Comparison of Expansive Pedicle Screws for Severe Osteoporosis: The Effects of Screw Design and Cement Augmentation. [PDF]

PLoS ONE, 2015
Expansive pedicle screws significantly improve fixation strength in osteoporotic spines. However, the previous literature does not adequately address the effects of the number of lengthwise slits and the extent of screw expansion on the strength of the ...

Understanding the influence of transfusion and blood loss on tranexamic acid concentration in scoliosis surgery with blood loss

British Journal of Clinical Pharmacology, EarlyView.
Aims Tranexamic acid (TXA) stabilizes clot formation by inhibiting fibrin degradation and improves postoperative outcomes. However, rare adverse events (e.g., thrombosis, seizures) warrant dose–risk evaluation. This study examines how perioperative blood loss and transfusion practices affect TXA concentrations during paediatric scoliosis surgery ...

Bone density optimized pedicle screw insertion

Frontiers in Bioengineering and Biotechnology, 2023
Background: Spinal fusion is the most common surgical treatment for the management of degenerative spinal disease. However, complications such as screw loosening lead to painful pseudoarthrosis, and are a common reason for revision. Optimization of screw

Placement of Thoracic Pedicle Screws [PDF]

JBJS Essential Surgical Techniques, 2016
Thoracic pedicle screws have become the spinal anchor of choice because of the superior biomechanics of this technique. It is widely used for the treatment of scoliosis, spinal deformity (such as kyphosis), trauma, tumors, infection, and other pathologies.

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.

Intra-operative computer navigation guided cervical pedicle screw insertion in thirty-three complex cervical spine deformities

Journal of Craniovertebral Junction and Spine, 2010
Background: Cervical pedicle screw fixation is challenging due to the small osseous morphometrics and the close proximity of neurovascular elements. Computer navigation has been reported to improve the accuracy of pedicle screw placement. There are very

ALT Rescue Flap With Iliac Crest Bone Graft and Spanning Plate for Mandibular ORN

The Laryngoscope, EarlyView.
In select patients with focal full‐thickness mandibular ORN defects, the use of ALTFL in conjunction with ICBG and a spanning reconstructive plate appears to offer clinical and radiographic arrest of ORN. This technique has considerably lower morbidity than osteocutaneous reconstruction, with abbreviated hospital stays, a low complication rate, and no ...
