PHTY200 Lecture Notes - Lecture 5: Myositis Ossificans, Rectus Femoris Muscle, Knee Effusion
Document Summary
Intramuscular: blood within intact muscle fascia results in increased intramuscular pressure. This compresses and limits the size of the hematoma. Intermuscular hematoma: develops if fascia surrounding muscle is torn and blood has access to spread into interstitial and interfascial spaces. In case of thigh knee effusion present, prone knee flexion. 5. 3 recognize the clinical signs of myositis ossificans. Increase in morning pain and pain with activity: night pain, palpable lump in area of injury. First degree: minor swelling and discomfort, minimal loss of strength, small restriction in movement, tear of few fibers. Second degree: significant swelling and discomfort, pain on contraction, loss of strength, restriction to movement, tear of significant number of fibers. Third degree: complete tear of muscle, virtual complete loss of muscle function: sprain: this is a stretching or tearing of ligaments. 5. 5 relate the anatomy and function of a muscle (muscle group) to injury risk and injury mechanisms.
