Odontoid fractures

MOJ Orthopedics & Rheumatology, 2018
Odontoid fractures account for approximately 7-15% (1) of cervical spine fractures, and almost 60% of fractures involving the axis. Neurological involvement is seen in upto 25% pts (2), and the primary mortality rate is around 12% (2). The mean age of occurrence is 47 years, with 2 peaks.

Novel Surgical Strategy System for Juvenile Nasopharyngeal Angiofibroma: A Focus on Feeding Artery Management

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 4, Page 410-418, August 2026.
ABSTRACT Objectives For intraoperative bleeding control in patients with juvenile nasopharyngeal angiofibroma (JNA), we developed a novel surgical strategy system. This system is focused on feeding artery management, based on the spatial relationship between the tumor entity and feeding artery as determined by three‐dimensional reconstruction.

Bulbar “Red Flag” Symptoms and a 21‐Year Diagnostic Delay in Adult Arnold–Chiari Type II Malformation With Tracheoesophageal Fistula and Syringomyelia: A Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT The simultaneous occurrence of Arnold–Chiari Malformation Type II (ACM II), syringomyelia, and an acquired tracheoesophageal fistula (TEF) in a young adult is exceptionally rare and represents a major diagnostic challenge. Arnold–Chiari Malformation II is characterized by the herniation of cerebellar structures through the foramen magnum.

Test–Retest Reliability of Sensorimotor Activity Measured With Spinal Cord fMRI

Human Brain Mapping, Volume 47, Issue 10, July 2026.
fMRI captured sensorimotor activation in hand‐related spinal cord regions, in accord with the established neuroanatomical organisation of the cord. While task performance reliability was good‐to‐excellent, the reliability of spinal cord activation was mixed.

Form and Law ‐ Rupert Riedl's Significance for Morphology

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 5, Page 383-389, July 2026.
ABSTRACT Rupert Riedl showed in his “Order in Living Organisms” that morphology can produce law statements and is, therefore, a proper, that is, nomothetic, science. Furthermore, he coined useful terms (interphene and metaphene) and concepts (burden, cadre and minimal homology).
