ATYPICAL FRACTURES 1) 2) 3) 4) 5) 6) Green stick Impacted Stress Pathological Hairline Torus Each long bone is numbered. First digit Bone Second digit Third letter AO/ASIF Segment 1–4 Type A – C Proximal & distal A - C Usually caused by directly applied force to fracture site Caused by violence transmitted through limb from a distance (twisting movements) Occurs in children: bones soft and bend without fracturing completely Fracture in cancellous bone: result of compression (osteoporosis) Two or more bone pieces - high energy trauma Bone fragments are impacted into each other. Abnormal stress on normal bone (fatigue fracture) or normal stress on abnormal bone (insufficiency fracture).
