Bone Distal Radius Fracture Essay - 1883 Words

Bone: Distal radius fracture, non-displaced, in a healthy middle-age adult. The primary cellular components of bone tissue are osteoblasts and osteocytes, and these are distinguished by their location and their function.1 The osteoblast is the bone-forming cell that eventually becomes an osteocyte. During this intermediate changeover, the cells are referred to as intermediate cells. â€Å"Bone matrix is comprised of three elements: organic, mineral, and fluid. Organic components constitute 39% of the total bone volume, which contains 95% type I collagen and 5% proteoglycans. Minerals include primarily calcium hydroxyapatite crystals and contribute about half of total bone volume.†1 Within the matrix, collagen fibers are responsible for providing tensile strength. Eventually, calcification and ossification of the fibrous matrix forms individual bony trabeculae that together constitute a primary ossification center.2 The arrangement of the collagen/trabeculae along the length of the bone give the bone its tensile strength; the resistive strength a gainst bending/breaking.1,2 The density of the bone is provided by calcium salts which are necessary to provide resistive strength against compressive forces, such as load/weight bearing activities.1 Stresses from weight bearing and using muscles provide the necessary stimulus for the formation and organization of collagen/trabeculae to form architecturally strong bones. Typically, when no injury or disease is present, boneShow MoreRelatedCode and Modifiers Used by Orthopedic Surgeons in Medical Specialities Pertaining to Injuries and Diseases991 Words   |  4 Pagesbodys musculoskeletal system.

This is a fracture of the distal metaphysis of the radius, which often has dorsal displacement leading to deformity commonly referred to as a dinner folk deformity. It is caused due to a fall on the outstretched hand (FOOSH). This type of fracture was first described by an Irish surgeon, Abraham Colles in 1814 (Radiopaedia, 2014). Epidemiology Colles fracture becomesRead MoreMidterm Review Anatomy 1 Lab1436 Words   |  6 Pagestail ~Dorsal- backside ~Ventral- belly side ~Proximal- nearer the trunk or attached end ex. the elbow is proximal to the fingers. ex. the knee is proximal to the toes ~Distal- farther from the trunk or point of attachment ex. the elbow is distal to the shoulder. ex. the fingers are distal to the elbow ~Superficial (external)-toward or at the body surface ex. the skin is superficial to the skeletal muscles ~Deep (internal)-away from the body surface ex. the lungsRead MoreAnatomy review1313 Words   |  6 Pagesskeleton?

A scaphoid bone is the largest bone at the upper portion of the carpal bones and plays a significant role in the articulation of the other carpal bones that make up the wrist movement (Purcell,2010). Seventy- one percent of carpal bone fracture occurs at te scaphoid waist (Nishihara, 2000). There is about five to twenty percent of fracture in the scaphoid, associated the other wrist or hand fractures (Malik, Yousaf, Khan, Ihsan Ravenscroft, 2010).

In osteoporosis the bones become weak and fragile. Since the bone mass is decreased the bones have more of chance to be opened to fractures. The bone is continuously breaking down by cells which is known as osteoclasts and rebuilding by other cells known as osteoblasts. As we age our bones begin to reabsorb more rather than they replace. Osteoporosis happens once the reabsorption causes the bones to reach a fracture threshold. AnyRead MoreThe Effects Of Osteoporosis On The Remodeling Cycle1114 Words   |  5 PagesOsteoporosis develops when the remodeling cycle, which is when the disruption of the bone resorption and bone formation occurs. The imbalance of the remodeling cycle causes osteoporosis. Hormones, cytokines, and paracrine stromal-cell interactions affect the osteoclast’s processes, which includes proliferation, maturation, fusion and activation. The osteoclasts are controlled by the interaction between several interleukins, tumor necrosis factor, transforming growth factor-beta, prostaglandin E2
