Know Your Skeletal System # Outlines • Brief anatomy • Organization of the bones • Types of bones • Joints – Fibrous joints – Cartilaginous joints – Synovial joints or diarthrosis and its types BRIEF ANATOMY Bone Development & others on its behalf....Bone, Whom am I? I am a specialized connective tissue. By providing a rigid skeleton, I give the all-important shape to the human beings. I am proud to be entrusted the job of protecting vital structures like brain, lungs and heart. I am the largest store-house of the all important mineral(i.e. calcium) in the body.I am also concerned with hemopoiesis(formation of blood with all its components). I give attachment to the muscles& enable them to act on the joints by acting as a lever for their action. I am made-up of 30% organic material(mainly type I collagen) & 70% mineral(calcium hydroxyapatite). Remember my Job then?! • Protection of vital organs • Support to the body • Hemopoiesis • Movement and locomotion • Mineral storage ...

General Principles of Fractures and Dislocations Outlines • Introduction • Definitions • Types of fractures • Approach to orthopedic injury • Investigations in orthotrauma • Management of fractures • Open fractures • Approach in compound fractures • Approach to a polytrauma case • Dislocations INTRODUCTION It is not surprising if a bone breaks but what is surprising is the fact that bone does not break more often considering the amount of forces it is subjected to everyday by the muscle action, load transmission,etc. Bone has devised its own mechanism to ward off the unnatural forces and keep itself intact. But only when the force is too large and occurs suddenly (as in road traffic accidents (RTA), fall, etc.), or when a force is chronic and repetitive (e.g. prolonged standing as in a policeman, nurse, etc.) or when the natural resistance of the bone is eroded by a disease process (e.g. tumor, infection, etc.), that a bone succumbs to the insult and breaks. When i...
