Cervical ligamentous injury with associated hydrocephalus secondary to posterior fossa subdural hemorrhage: a case report.

Traumatic subdural hematomas (SDHs) in the posterior fossa in conjunction with cervical spinal hematomas are rare entities. In this case, we present a 22-year old man who presented to our institution with ligamentous injury at the cervicomedullary junction, associated with posterior fossa SDH not discovered initially, who on serial computed tomography scans was found to have symptomatic obstructive hydrocephalus and was successfully treated with SDH evacuation and stabilization of the cervicomedullary junction with instrumentation.

Technical strategies and anatomic considerations for parapedicular access to thoracic and lumbar vertebral bodies.

Objectives: To investigate and illustrate a variation on the traditional percutaneous access to the vertebral body via a parapedicular approach.

Design: An effective parapedicular access technique that could safely and reliably guide the needle tip into the center of the vertebral body was developed from cadaver dissection observations for the purpose of clinical use.

Patients: A total of 102 vertebral compression fractures from T-4 to L-5 were treated via the parapedicular access at our institution between July 2005 and March 2006.

Reversal of neurologic deficit in an adult gorilla with severe symptomatic lumbar stenosis.

Study Design: A case report is presented.

Objective: To describe a case of severe symptomatic lumbar stenosis in an adult gorilla successfully treated with decompressive surgery.

Summary Of Background Data: Although spinal degenerative disease is thought to be less common in apes than in humans, gorillas and bonobos are known to have higher rates of disease than other African apes.
