- Treat every sprain/strain like a fx RICES Amputations - control for shock Compartment Syndrome - usually fx tibia in adults - forearm in PEDs - 6 to 12 hours after injury - ↑ pain compared to injury on passive stretch (+ pallor, ↓ sensation, ↓ power) - Treatment Elbow - no distal pulse = emergency - ie splint in found position and xfer - elbow: traction and attempt restore of pulse Treatment Pelvis - retroperitoneal space: b/n ab mm and posterior wall - ↑ blood supply + space = ↑ change for internal bleeding - palpate symphysis for dislocation Hip Dislocation - TTP, femoral head in mm of buttock- sciatic nn injury Hip Fx - through neck of femur - proximal: short leg in ER - pain can radiate to knee Femoral Shaft - thigh mm spasm to "splint" limb - limb shortens significantly - 500 to 1,000mL blood loss - ↓ circulation = traction + alignment Knee Dislocation - true emergency, significant defoormity - popliteal artery compromised - don't straighten, splint bent - med control says straighten? only ONCE Fx Knee - no tx splint - pulse = splint - no pulse = med control Patella Dislocation - laterally, splint it Tib/Fib - splint + secure to opposite legAnkle - correct gross deformity + splint Describe the anatomy and physiology of the musculoskeletal system.
