Anatomy: Case Study Questions & Answers 100% All Verified 2022/2023 Describe the healing of the head lacerations, and the role of sutures in that process. - ANS--Wound Healing Process: 1. Severed blood vessels bleed 2. Inflammatory chemicals are released 3. Local blood vessels become more permeable, allowing WBCs, fluid, clotting proteins, and other plasma proteins to seep into the injured area 4. Clotting occurs; surface dries and forms a scab 5. The clot is replaced by granulation tissue, which restores the vascular supply 6. Fibroblasts produce collagen fibers that bridge the gap 7. Macrophages phagocytize dead and dying cells and other debris 8. Surface epithelial cells multiply and migrate over the granulation tissue 9. The fibrosed area matures and contracts; the epithelium thickens 10. A fully generated epithelium with an underlying area of scar tissue results -Sutures hold the edges the laceration together to: • Reduce size • Speed up healing process • Improve appearance • Improve tissue function Describe the reduction and immobilization of the three leg fractures (specific to the patient's injuries), and how the bone will subsequently heal. - ANS-• open reduction and repair with hardware o due to the amount of fractures and the femur fracture (since it is a major fracture), even though the fracture is displaced but is not open healing process of fractures • fractures will be immobilized o cast or boot keep the bones still during the healing process -Fracture Healing Process: 1. Hematoma formation - clot forms, then osteogenic cells form granulation tissue 2. Soft callus formation - fibroblasts produce fibers and fibrocartilage 3. Hard callus formation - osteoblasts produce a bony collar in 6 weeks 4. Bone remodeling - spongy bone replaced by compact bone Give a possible explanation for why the fractures are all right leg. - ANS-all the fractures are on the right leg because you use your right leg to drive.
