We report the early results of 10 consecutive metal-on-metal resurfacing arthroplasties performed between May 2006 and July 2007 in young, active patients with gross femoral head defects. Failure was classified as revision for any reason. The mean age of our cohort at the time of surgery was 42.8 years and the minimal period of follow-up was 6.9 months. No patients were lost to follow-up. Up to the time of last review, there were no failures and all patients have returned to their preoperative levels of activity. This study shows promising early results of a bone-conserving, hydroxyapatite-coated, uncemented metal-on-metal bearing prosthesis in young, active patients with bony defects of the femoral head.

Department of Communication Sciences and Disorders, Bowling Green State University, OH.
Purpose: The current project aimed to examine the effects of two experimental cognitive-linguistic paradigms, the Stroop task and a primed Stroop task, on speech kinematics and perioral muscle activation.
Method: Acoustic, kinematic, and surface electromyographic data were collected from the verbal responses of 30 young adult healthy control participants in choice response, classic Stroop, and primed Stroop tasks. The classic and primed Stroop tasks included congruent and incongruent trials.
