This reduces friction between articulating bone • Periosteum – dense, white fibrous covering which penetrates bone via sharpey fibres • Contains blood vessels and osteoblasts Most fractures occur at the diaphysis Acute Bone Fractures • Open fractures break the skin • Partial or complete disruption that can be either closed or open (through skin) • Acute bone fractures have serious musculoskeletal conditions • Acute bone fractures presents with deformity, point tenderness, swelling and pain on active and passive motion • With fractures, There will be sharp, point specific pain Greenstick fracture • When we have An incomplete fracture that occurs on the convex surface, concave surface stays intact • We see this in youth. Comminuted fracture • 3 or more fragments in this fracture • Due to hard blow or awkward fall • Difficult healing situation • Sometimes it will have to be surgically repaired • Screws will have to be put in and it takes a long time to heal Transverse fracture • Occurs in a straight line • MOI will be an object impact.
