In the pigeon, as in other members of the three groups of vertebrates which have developed advanced powers of flight—the birds, bats and pterosaurs—the bending and torsional strength of the proximal part of the wing lies in the humerus and radio-ulna. The humerus runs obliquely back from the shoulder joint to the elbow, and from there the radio-ulna runs obliquely forward to the wrist. In fligh...

Incisional biopsy and intramedullary pinning were performed for pathological fracture associated with a malignant bone tumor of the proximal humerus. Osteosarcoma, for which preoperative chemotherapy had been performed, was confirmed by postoperative pathological examination. To achieve wide resection and acquire a safe resected margin, total humerus replacement was performed, and the whole hum...

Distal humerus fractures are uncommon, comprising 2% of all fractures and a third of all humerus fractures. Open fractures, comminuted fractures and fracture dislocation of the elbow are often accompanied by severe soft tissue damage. External fixation of the humerus is indicated when severe soft tissue damage or the presence of infection warrants initial alternative immobilisation of the fract...

We report a patient who had resection of the humerus for osteosarcoma, initial reconstruction with a free fibular graft of the humerus, and subsequent lengthening of the graft. A 9-cm (100% of free fibula length) lengthening was achieved to equalize the humerus length. A complication of regenerate fracture was treated successfully with plating. Four years after the initial surgery for lengtheni...

conclusions the causes leading to fracture of the humerus during the act of a throw are discussed and the management strategies utilized. introduction five patients presented to the emergency department of a tertiary referral teaching hospital with atraumatic fractures of their humerus sustained during a recreational dodgeball tournament. case presentation the patients were young healthy indivi...

The patient was an 18-year-old high school baseball pitcher with a chief complaint of right (dominant) arm pain in the region of his right distal humerus that began 8 weeks earlier. Conventional radiographs were obtained, which were interpreted as normal. As a result, magnetic resonance imaging was obtained, which showed a hyperintense bone marrow signal in the distal humerus on fluid-sensitive...

Introduction: Intramedullary nailing is a good indication for stabilizing displaced fractures of the proximal end and shaft humerus in adults. Methods: This was prospective series 24 patient, over period 9 months. The aim this study to report epidemiological clinical aspects patients treated with locked humeral nail show medium-term interest, therapeutic method, thus discussing complications. R...

BACKGROUND Supracondylar humerus fractures are very common types of elbow fractures in children between the ages of three and ten years. Totally displaced supracondylar humerus fractures can be associated with neurovascular injuries, and treatment can be complicated by iatrogenic neurovascular injury, compartment syndrome, malunion, and elbow stiffness. AIM The aim of this study was to descri...

Heterotopic ossification is a common complication of Orthopaedic Trauma Association (OTA) type C distal humerus fractures and ulnohumeral fracture dislocations. The purpose of this study was to precisely define the incidence of heterotopic ossification following major elbow trauma and to identify risk factors for the development of clinically significant heterotopic ossification and for surgica...
