External skeletal fixation constitutes a complete modular system ,allowing construction of linear, hybrid, and circular external fixators to treat orthopedic conditions from fractures to angular limb deformities.Common pins, clamps, wrenches, drill sleeves and many other components are designed to function interchangeably. Modularity allows the veterinary surgeon using the linear fixator to add hybrid fixation to his/her armamentarium quickly and affordably without the need to purchase another device and/or instrument set.
