Pages 2 This preview shows page 1 - 2 out of 2 pages. A fracture hematoma forms. Cells called osteoclasts constantly break down old bone so that osteoblasts can replace it with new bone tissue -- a process called bone remodeling. 2. Whenever a bone breaks, the blood vessels running down the length of the bone are severed. Bone remodeling serves to adjust bone architecture to meet changing mechanical needs and it helps to repair microdamages in bone matrix preventing the accumulation of old bone.

Bone formation, process by which new bone is produced. Comminuted- bone breaks into many fragments, break that does not penetrate the skin. In the early stages of embryonic development, the embryo’s skeleton consists of fibrous membranes and hyaline cartilage. D) Blood-forming tissue is found in the skull and pelvic bones only. Another type of cell called a chondroblast forms new cartilage. The blood begins to clot, and about six to eight hours after the fracture, the clotting blood has formed a fracture hematoma (Figure 2). B. Irregular bones include the vertebrae and hip bones.

Figure 6.5.2 – Stages in Fracture Repair: The healing of a bone fracture follows a series of progressive steps: (a) Broken blood vessels leak blood that clots into a fracture hematoma. blood escapes from ruptured blood vessels and forms hematoma, spongy bone forms in regions close to developing blood vessels, fibrocartilage forms in distant regions, osteoclasts remove excess bony tissue and restore new bone structure to original form, Factors that Influence Bone Development, Growth, and Repair, Vitamin D, Growth Hormones, Sex Hormones, Physical Exercise, low levels cause poor absorption of calcium in small intestine, low levels in salt portion of bone matrix softens and deforms bones, secreted by pituitary gland, stimulates division of cartilage cells at epiphyseal plate, stimulates ossification of epiphyseal plates, pulling on muscular attachments to bones adds stress and thickens and strengthens bones, reduction and immobilization so bone can realign, bone fragments into 3 or more pieces, common in elderly and brittle bones, bone is crushed, common in porous bones subjected to extreme trauma, ragged break occurs when excessive twisting forces applied to bone, common in sports, epiphysis separates from diaphysis along epiphyseal plate, usually occurs where cartilage cells are dying and matrix calcification occurring (kids), broken bone portion is pressed inward, typical of skull fractures, bone breaks incompletely, only one side of shaft breaks and other bends, common in children whose bones have more organic matrix so are more flexible, complete break, right angle to axis of bone, usually caused by force applied directly to site, fractures too unstable for cast, you can shower and gently use bone, allows correction of deformities by moving pins in relation to frame, most common metabolic bone disorder, low bone mass, microarchitectural deterioration of bone tissue, increases fragility.

Our website is 100% ad-free and not for profit. There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone. Calcium levels in blood determine when remodeling takes place, pull of gravity determines where remodeling will take place. Woven bone is replaced by compact bone Fibers and cartilage of the calluses are replaced by spongy bone A localized mass of blood called a hematoma is formed. As a result, a blood filled swelling a hematoma forms. The process takes two general forms, one for compact bone and the other for cancellous bone.
