Bone Fixation Methods in Veterinary Surgery

The fixation of bone fragments is crucial for stabilization during the healing process in veterinary surgery. This process aims to prevent displacement, angulation, and rotation. Various methods such as limb splintage, bone splintage, and compression techniques are utilized to achieve uninterrupted stabilization, facilitate early ambulation, and allow the use of multiple joints during the healing period. Temporary splintage methods like coaptation splints and casts are also employed to minimize additional trauma and enable the early reduction and fixation of fractures.

  2. Objectives of the fixation • Stabilization of bone fragments during healing process • Prevent displacement, angulation, and rotation. • Fixation method used should • Accomplish uninterrupted stabilization at the time of the original surgery • Permit early ambulation • Permit the use of as many joints as possible during the healing period Objectives of the fixation Fixation method used should

  3. Methods of Fixation • Limb splintage Thomas splint) • Bone splintage fixator, bone plate) • Compression wire, tension band wire, tension band/compression plate) Methods of Fixation Limb splintage (coaptation splints, casts, modified Bone splintage (intramedullary pin, external skeletal Compression (lag screw, cerclage/interfragmentary

  4. • The compression may be static in nature, as with a lag screw or cerclage wire, in which case the compression is not expected to change with time. • Dynamic compression, on the other hand, does change cyclically with loading of the limb as limb function periodically loads and bone surfaces.

  5. Temporary Splintage • Used to reduce additional trauma when delay in reduction and fixation for some reason is suspected • Temporary splintage(e.g., Robert-Jones dressing, c oaptation splint, Thomas splint) of the limb • Fractures distal to the elbow and stifle • The objective in most fracture cases is early reduction and fixation Temporary Splintage

  6. Coaptation Splints and Casts • “coapt” meaning to approximate • External casts, splints, and bandages are often called “coaptation fixation devices • Rigid materials such as fiberglass, plaster, and splint rod provide the mechanical strength and stiffness required in external coaptation, but these may also endanger the splinted limb if used improperly • Approximate can be accomplished by • Simply immobilizing muscles, as with a bandage • by transmitting compression forces to the bony structures by means of the interposed soft tissues, as with casts and splints Coaptation Splints and Casts

  7. Casts & splint Casts & splint • Molded tubular structures
