Observations of canine tibias lengthened by continuous transphyseal distraction (without osteotomy) reveals an acute fracture through the metaphyseal zone of primary trabeculae and rapid osseous healing. Long-term follow-up demonstrates normal subsequent growth.
The reinforcement of polymethylmethacrylate with small caliber stainless steel fibers can significantly improve its mechanical properties. While maintaining all the advantages of unreinforced polymethylmethacrylate, it can be demonstrated that compression, flexural tension, tension and impact parameters of cement reinforced with one quarter inch long steel fibers are dramatically enhanced. Careful cement preparation further improves these properties. The polymerizing composite is easily prepared within the operating room and the exothermic reaction is not as severe as the unreinforced material. Furthermore, the metal fiber reinforcement provides the potential for core heating, the capability of depolymerization to facilitate cement removal, and invites research on new prosthetic stem designs.
Leg length increments utilizing continuous traction across the epiphyseal plate of growing puppies produces a cleavage fracture at the level of the primary metaphyseal trabeculae which neither anatomically nor physiologically alters the growth plate. These fractures heal readily and growth resumes following removal of the traction device. This method is relatively atraumatic to the extremity. It does not require an open operation and the controlled distraction rate has not caused neurological or vascular complications. The study was designed to determine the anatomic site of fracture; no attempt was made to achieve maximal leg length increments.
