Case Reports
Single-stage anterior autogenous bone grafting and instrumentation in the surgical management of spinal tuberculosis.
Results of single-stage anterior autogenous bone grafting and instrumentation for spinal tuberculosis were reported. ⋯ The authors think that the single-stage anterior autogenous bone grafting and instrumentation are a safe and effective method in the surgical management of spinal tuberculosis.

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.

A retrospective study was undertaken which evaluated the medical records and imaging studies of a subset of patients managed by the spine service at Jackson Memorial Hospital who were diagnosed with an esophageal perforation in the setting of spinal surgery. ⋯ The use of an SCM flap for the repair of esophageal injury, in the setting of anterior cervical spine surgery, is a safe and effective tool. An SCM flap appeared to improve the time in initiating oral intake without any significant morbidity.

Retrospective chart review. ⋯ Gunshot wounds to the head and neck had a high rate of concomitant cervical spine fracture. Neurologically intact patients have a lower rate of fracture than those presenting with a spinal cord injury or altered mental status. In this small series of patients, the only unstable cervical spine injuries were detected in patients with a spinal cord injury. The data suggest that spinal precautions and/or a hard cervical collar should not be maintained at the expense of delaying or hindering emergent life-saving airway or hemodynamically stabilizing procedures, particularly in awake, neurologically intact patients. However, the cervical collar and spinal precautions should be resumed after such procedures are completed and continued until a more definitive evaluation of spinal stability can be performed.

A new type of composite device with a similar structure to a natural lumbar intervertebral disc was modeled, and its mechanical interaction with a L3-L5 lumbar spine segment was studied by a finite element analysis. ⋯ By using numerical methods, this study allows prediction of the static mechanical behavior of a new device within a lumbar spine structure, which appears very useful for preclinical study.
