Document Summary
Healing process: repair, regewneration, and formation of scar tissue. Fibrolastic repair phase- scra tissue sppears, type 3 collagen. Maturation remodeling phase finalizatipn of scar tissue, wolf"s law is applied. Phase begins immediately and lasrs 48 to 72 hours overlapping into a fourth day. Signs of inflammation: redness, swelling, heat, pain, and loss of function. Overlapping from fourth day up to 6 weeks. General purpose: gradual repair and remodeling, leading to formation and increase tensile strenght of scar tissue. Collagen: strong fibrous protein found in connective tissue. Overlappingfrom a few weeks and extending months and possibly years towards completion. General purpose: continuous remodeling towards final scar tissue. Collagen fibers aling along direction of tissue tension. 80 90% exist as type one, type two, or type three. Wolf"s law: bone and soft tissue will respond to physical demands placed on them, causing them to remodel and realign along line of tensile forse.
