OBJECTIVE To test a crimp clamp system designed to secure monofilament nylon leader (MNL) material commonly used as lateral fabellotibial sutures (LFS) in extra-articular stabilization of the canine stifle joint. STUDY DESIGN In vitro biomechanical tests of MNL loops secured with either the crimp clamp system or knots were performed. Suture loops (n = 94)(More)
Eighty-two children and adolescents between the ages of 30 months and 20 years (mean, 11.8 years) who were admitted to one of two pediatric burn units with a mean initial burn injury of 43.8% total body surface area and a mean age at time of injury of 4.2 years were studied 1 year or more after burn injury (mean, 7.3 years). Subjects were found to have(More)
