I. INTRODUCTION Background and rationale of the study: One of the leading cases of musculoskeletal trauma is fracture. Fractures are any break in the continuity of the bone. It usually occurs when the stress placed on a bone is greater than the bone can absorb. Muscles‚ blood vessels‚ nerves‚ tendons‚ joints and other organs may be injured when fracture occurs (Nettina‚ Sandra B. 2006). It can be caused by metabolic bone diseases such as osteoporosis‚ or as a result of direct force when

is known as static failure. Stage 3: Final Fracture (Instantaneous Zone) – Crack lengthens‚ decrease in load support‚ final failure. 3. How is fatigue in metals recognized? Fatigue in metals is recognized through the investigation of the fatigue zone. From the investigation‚ we are able to determine the origin of the crack‚ type of loading‚ direction of loading‚ and stress intensity. The ductility of a metal is recognizable by the shear type fracture surface. The stop marks and herringbone pattern

Based on the location and severity of the fracture‚ a broken bone usually must be set into position and supported until it is strong enough to bear weight. Your physician will recommend the most proven treatment approach‚ usually casting or surgery 2.

Kyphosis also known as “hunchback” occurs when the vertebrae in the upper back are wedge shaped instead of cylinder. This disorder can be caused by a number of things such as: Osteoporosis‚ Disk Degeneration‚ slouching/poor posture etc… Kyphosis can happen at any age but it’s most common in older women. In addition to an abnormally curved spine the symptoms can also cause back pain and stiffness in some people. Mild cases of kyphosis may produce no noticeable signs or symptoms. Depending on what

Losing bone density and muscle strength is a natural part of aging. However‚ certain medical conditions can make these processes even worse‚ putting sufferers at even higher risk of bone fractures and other injuries. Osteoporosis is one of these common conditions.

a surgeon/physician who has to operate on injured bones and muscles in the musculoskeletal system. This career is embedded within the health/science career cluster. I enjoy playing all sports from cycling to football. Having experienced multiple fractures myself‚ I have always been curious about the latest research in this field. As an orthopedic surgeon‚ I would feel privileged to serve all my fellow sports enthusiasts and help them get back to their game as soon as possible.
