Document Summary
Inflammation: 24 hrs to 3-4 days after: myofibers rupture and necrosis, hematomas. Repair: 5 days 2 weeks: phagocytosis of necrotic fibers regeneration of myofibers formation of scar tissue, capillary ingrowth. Remodeling: 14 days onwards to 21+ complete will take sometimes up to 2 yrs (tendon: maturation of myofibers, contraction and organization of scar tissue recovery of function. Muscle injury d/t sudden heavy compression force. Ii moderate 4-6wks may walk with limp, can continue sport. Iii severe 8 wks - immediate swelling, unable to walk. Complications: compartment syndrome check capillary refill and sensation, muscle strength, myositis ossification suspect if haven"t improved after 2-3 wks. Majority occur in bi-articular mm @ mm-tendon junction: mainly occurs during eccentric loading. Risk factors: prior injury, age, no used to activity, training errors, biomechanics (poor control, inflexible) I microscopic tearing pain, no weakness. Ii macroscopic tearing pain + structural change (laxity, decreased strength) Iii complete tear painless + weak, may see lump.
