BIOL 207 Study Guide - Midterm Guide: Vitamin D Deficiency, Bone, Epiphyseal Plate
Document Summary
Treatment involves reduction: realignment of bone ends. Closed external reduction: coax bone ends into position. Open internal reduction: bone ends secured together surgically w/pins/wires. Simple fracture small/medium size bones in young adults: 6-8 weeks. Longer for larger and older due to poor circulation: hematoma forms. Bone fragments into 3 or more pieces. Common in aged (brittle bones: spiral. Ragged break occurs when excessive twisting forces. Common n porous bones (osteoporotic bones) subjected to extreme trauma (fall: epiphyseal. Epiphysis separates from diaphysis along epiphyseal plate. Tends to occur when cartilage cells dying and calcification of matrix is occurring: greenstick. Bone breaks incompletely, only one side of shaft breaks, other side bends. Common in children whose bones have more organic matrix and more flexible than adults. Increase vitamin d intake, exposure to sun cures disorders. Dislocation of tmj (temporalmandibular joint) can occur easily because shallow socket in joint [deep yawn] Dislocates anteriorly, condylar process ends in infratemporal fossa mouth wide open.
