Incidence of intracranial bullet fragment migration.

Migration of retained bullets or bullet fragments may present as a complication of gunshot wounds to the head. This phenomenon has been reported in cases of abscess formation or retained copper fragments. Management of such migratory fragments is controversial.

Coincidence of head and cervical spine injury.

The association of head and cervical spine injury has long been recognized. Reports of the coincidence of these injuries in the literature range from 1.2 to 19%.

Role of Roux-en-Y feeding jejunostomy for patients with acute head injury.

The total care of a patient with severe head injury is challenging and may extend for weeks, months, or even years. A major challenge of this care includes nutritional support: swallowing is impaired, aspiration accompanies gastric tube feeding, parenteral nutrition is limited to short term in hospital care, and needle jejunostomy or transabdominal jejunostomy are prone to inadvertent removal. The role of Roux-en-Y feeding jejunostomy was evaluated in 13 patients with acute head injury.

Lumbar discectomy--percentage of disc removal and detection of anterior annulus perforation.

A prospective study was carried out to estimate the percentage of disc removal at the time of lumbar laminectomy and discectomy. Intraoperative discograms were obtained which afforded a method of calculating the percentage of disc removal. The technique permits localization of the level of discectomy and provides a means of detecting anterior annulus perforation intraoperatively, which we hope will reduce the morbidity of anterior annulus perforation.
