Document Summary

Transitional vertebra; vertebra on both sides of a major division of the spine: most commonly at the lumbosacral junction and contain expanded transverse processes. At the thoracolumbar junction, the first lumbar may have rudimentary ribs articulating with the transverse processes. The cervicothoracic junction may also have a rudimentary rib: first rib should start at t1. Complications of cervical rib: thoracic outlet syndrome: numbing, nerve damage, problems with their arm. Incomplete acetabulum formation caused by physiological and mechanical forces. During pediatric assessment, when the leg is flexed and abducted, the hip may pop out of place and make a click sound. Tendons and ligaments responsible for femoral head alignment are affected. Imaging: ap: normal or with only slightly larger joint space, bilateral frog leg: hip dislocated superiorly and posteriorly, many follow up exams; important to shield gonads, ultrasound. Treatment- depends on if it is subluxation vs dislocation of femoral head.
