Title was changed:
Hypoplastic right 12th right rib
Status changed from pending review to published (public).
Published At was set to .
Presentation was changed:
Back pain on a 12 year old boy after falling from a horse. Initial suspicion of right transverse process fracture of the first lumbar vertebra.
Body was changed:

At first, due to the back pain presented by the patient and the x ray-ray images, it was thought to be a right transverse process fracture of the first lumbar vertebrae, but a better second better look proved to be a hipoplastichypoplastic right 12th rib, associated to an agenesis of the left 12th rib.

Although the risks to humans of interacting with horses are well known, therehave been no significant reductions in rates of injury or death over the past decades. In contrast,there have been significant decreases in injuries and fatalities in high risk workplace settings such asmining and construction.1.

Lumbosacral transitional vertebrae (LSTV) are congenital anomalies of the lumbosacral region which includes lumbarization and sacralization,observed, observed for the first time by Bertolotti. This condition occurs due to defect in the segmentation of the lumbosacral spine during development. The transitional vertebra may have varying formations, the common feature being an atypical lumbosacral articulation between the transverse process of L5 and the sacrum.2.

Updates to Study Attributes

Findings was changed:

Hypoplastic right 12th rib and agenesis of the left 12th rib, simulating a right transverse processes fracture of the first lumbar vertebra. There is also a lumbosacral transitional vertebra with a neo-articulation between a large right mega apophisis tranversetranverse process and the sacrum.

Description was changed:
Counting from the first rib, there is only eleven pairs of ribs normalynormally formed.
