The spinal column is the central structure in the vertebrate body from which stability, movement, and posture all derive. The vertebrae of the spine are organized into four regions (listed in order from cranial to caudal): cervical, thoracic, lumbar, and pelvic. These regions are classified by their differences in curvature. The human spine usually consists of thirtythree vertebrae, seven of wh...

RISK OF INJURY AT THE CERVICAL LEVEL during automotive crashes is difficult to assess. Injury tolerance values were shown to be very dependent from intrinsic or extrinsic parameters and their relevance is still controversial. The curvature of the human neck presents a great variability (Matsumoto 1998) and may be influenced by a seated posture (Black 1996). The aim of this study is to assess th...

We here report the case of a G2P2 patient hospitalized for premature labor at 38w+3d. Phisical examination showed full cervical dilation, water breaking and fixed face presentation. Fetal heart rate tracing was evaluated as normal. The patient underwent cesarean section due to face presentation. Physical examination of the newborn in the delivery room revealed female infant, PN = 3.7Kg, with re...

Idiopathic scoliosis is a common disorder characterized by abnormal curvature of the spine with onset typically in adolescence. Adult-onset primary torsion dystonia (AOPTD) is a focal dystonia with onset in early-middle age consisting of abnormal twisting or directional movements and postures; common phenotypes include cervical dystonia, blepharospasm, and focal hand dystonia. Numerous case rep...
