Effect of disk fenestration on sagittal kinematics of the canine C5-C6 intervertebral space.

Objective: To determine the effect that ventral intervertebral disk fenestration has on the sagittal range of motion about the C5-C6 intervertebral space.

Study Design: A repeated measures in vitro mechanical study of spinal range of motion under controlled loading conditions before and after fenestration.

Sample Population: A total of 10 canine cervical vertebral specimens (C4-C7) collected from clinically normal animals within 12 hours of euthanasia.

Slipped capital femoral epiphysis: a physeal lesion diagnosed by MRI, with radiographic and CT correlation.

Objective: To define and compare early lesions associated with slipped capital femoral epiphysis (SCFE) on magnetic resonance imaging (MRI), computed tomography (CT) and radiography.

Design And Patients: Thirteen patients with 15 symptomatic hips due to SCFE underwent radiography and MRI; CT was performed in 12 patients. SCFE was graded on radiographs, head/neck angles and qualitative changes were evaluated on CT, and morphologic/signal abnormalities were determined on MRI.

A classroom activity to introduce cultural diversity.

The authors describe an activity designed to introduce cultural diversity to an undergraduate developmental psychology course in a nursing baccalaureate program. The students' responses to the activity served as the basis for a discussion of stereotypes and their effects on culturally diverse populations. The student responses are described and the importance of introducing cultural diversity into mainstream education is discussed.
