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.

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.

An updated Cochrane review. ⋯ No conclusions are possible about the relative effectiveness of anterior, posterior, or circumferential fusion. The preliminary results of three small trials of intradiscal electrotherapy suggest it is ineffective, except possibly in highly selected patients. Preliminary data from three trials of disc arthroplasty do not permit firm conclusions.

Review Case Reports
A traumatic central cord syndrome occurring after adequate decompression for cervical spondylosis: biomechanics of injury: case report.
Case report with review of the literature. ⋯ Decompressive laminectomy provides an immediate decompressive effect on the spinal cord as seen by the dorsal migration of the cord, however, the biomechanics of the cervical spine after decompressive laminectomy remain uncertain. This case supports the ongoing research and need for more intensive research on postoperative cervical spine biomechanics, including decompressive laminectomies, decompressive laminectomy and fusion, and laminoplasty.

Review Case Reports
Intraoperative visible bubbling of air may be the first sign of venous air embolism during posterior surgery for scoliosis.
Case report of two children sustaining venous air embolism (VAE) during posterior surgery for scoliosis. ⋯ Visible air bubbling at the operative site may herald the onset of massive VAE during multilevel posterior spinal fusion and instrumentation. A prospective multicenter study using precordial Doppler, central venous catheter, and end-tidal CO2 is recommended to determine the true incidence of VAE in spinal deformity surgery and to evaluate monitoring and treatment methods.
