Name two specific fractures or instances where a surgeon might use an external fixator device.

- Wrist or forearm fx -long bone fx -when infection is also present -severe comminuted fx -pelvic fx -when severe swelling occurs

What are the three stages of bone healing, and what occurs during each phase?

-Inflammatory: Blood from the bone and surrounding tissue collect at the fracture site and clot and fibroblasts in the area of the injury create a network of granulation tissue. -Reparative: Growth cells from the periosteum develop into rudimentary bone cells and cartilage which forms a callus. Ossification later occurs as this soft callus is replaced by bone cells and minerals. -Remodeling: Takes place over a period of weeks or months, the initial bone matrix is replaced with compact bone and the excess callus is absorbed

Beside strict adherence to aseptic technique, explain 2 specific ways the ST alone can promote avoidance of an infection during a total joint replacement.

-change gloves after draping and every 2 hours -wear hoods -limit traffic -double glove care with draping -minimize handling of implant

Place the stages of fracture healing in order: (1) hematoma formation, (2) remodeling, (3) fibrin network formation, (4) callus formation, (5) invasion of osteoblasts.
