title: [Use of an internal fixator in the femur and tibia. Clinical and roentgenological course in animals].
abstract: The applicability of a new internal fixator was tested in the femur and tibia of sheep. The device was primarily developed for the spinal column by the association for studies of internal fixation (ASIF). For this investigation 12 sheep were subjected to transverse osteotomy and the bones were then stabilized with a internal fixator: The clinical and radiological follow up shows a stable healing process of the osteotomy within 8 weeks despite full load-bearing on all extremities. During the entire study period the sheep had full freedom of movement. Clinical and radiological observations were confirmed by the results of histological examinations. The results allow the following conclusions: in view of the course of recovery the indications for application of a internal fixator can be extended to fractures of the lower extremities. Further studies pertaining to the suitability of the implant for various fracture types are in progress. The great advantage of this fixation technique is that the fixator is mounted without any damage to either the endosteal or the periosteal circulation.
