A large animal model to assess fetal fracture repair and the ability to close excisional bony defects is presented. Incisional and excisional ulnar fractures were made in 14 midgestation fetal lambs, harvested at serial time points, and subjected to high-resolution low-kilovolt magnification radiographs, magnetic resonance imaging scans, and histologic(More)
Seven patients aged six to 25 underwent progressive distraction lengthening of the forearm. Five had lengthening of the ulna and two of the radius. Four cases had multiple exostoses, two had post-traumatic distal epiphyseal arrests and one had dyschondrosteosis. Two methods were used: the Wagner technique of diaphyseal distraction and bone grafting, or(More)
Thirty children aged between 2 and 10 years with fractures of the femoral shaft were involved in a prospective study of a treatment method that requires a short period of traction followed by full weightbearing with a modified hinged functional brace and return to school after an average of 32.5 days. At an average follow-up period of 2 years, no case has(More)
We compared the strength of a new step-cut technique for flexor tendon repair with that of the widely used Kessler-Tajima technique, giving special attention to the relative contributions of the core and epitendinous sutures. 36 flexor digitorum profundus tendons from human cadavers were used. Corresponding digits from the same donor were paired, and the(More)
Postexercise cold water immersion has been advocated to athletes as a means of accelerating recovery and improving performance. Given the effects of cold water immersion on blood flow, evaluating in vivo changes in tissue oxygenation during cold water immersion may help further our understanding of this recovery modality. This study aimed to investigate the(More)
