Humerus fracture physically active young adult men who experience physical trauma to the humerus. Distal fractures are rare among adults, occurring primarily in children who experience physical trauma to the elbow region. Humerus fracture A humerus fracture is a break of the humerus bone in the upper arm. Symptoms are pain, swelling, and discoloration of the skin at the site of the fracture. Bruising appears a few days after the fracture. The neurovascular bundle of the arm may be affected in severe cases, which will cause loss of nerve function and diminished blood supply beneath the fracture. Proximal and distal fractures will
Bone cyst who called these lesions "homerus ossifying haematoma". In 1940 Ewing used the term "aneurismal" to describe these lesions. Jaffé and Lichtenstein first coined the term "aneurismal cyst" in 1942 In 1950 they modified this term to "aneurismal bone cyst". They may be associated with bone tumors. The simple bone cyst is a common, benign, fluid-containing lesion, most commonly found in the metaphysis of long bones, typically the proximal humerus or femur. Pathologic fractures are common, often with minor trauma. These cysts typically resolve after skeletal maturity and are not typically associated with bone tumors. The cause is unknown. These were
