To investigate the effects of biologic age, as well as chronologic age, on the vertebral ultimate load (strength) and risk score of vertebral fracture (Phi) between the genders. ⋯ Our findings emphasize the importance of Phi, which considers BMC, bone size, body weight, body height, and weight lifted, for evaluating a more individualized risk of spine fracture in elderly men and postmenopausal women. The Phi increased more prominently with lifting weight and increased with aging only in the early postmenopausal females. The study showed that a combination of bone mass and anthropometric parameters provides a more individualized assessment of fracture risk than bone mineral density alone.

Details of presentation and approach to the treatment of scoliosis in a case of a Rigid Spine Syndrome (RSS). ⋯ The chromosomal bases of CMD and characteristic features of RSS, including diagnostic tests, have been reviewed. Surgical intervention with spinal deformity fusion, correction, and instrumentation is indicated in RSS with progressive spinal imbalance not responding to conservative therapy is safe and can give promising results.

A report of 3 cases of upper sacral tumors excised by occluding the abdominal aorta with a balloon dilation catheter (BDC). ⋯ To occlude the abdominal aorta with a BDC may effectively reduce intraoperative hemorrhage, thus assisting the surgeon in the complete and safe resection of upper sacral tumors.

Giovanni Alfonso Borelli is often described as the father of biomechanics. He was born in Naples in 1608. ⋯ Borelli died in Rome on December 31, 1679, but his impressive body of original work helped inspire a great number of future scientists, microscopists, and inventors. The highest honor bestowed by the American Society of Biomechanics is the Giovanni Borelli Award.
