HUMERUS RADIUS ULNA, CARPAL BONE FRACTURES DR. MURAT CALISKAN
Chest injuries, particularly pneumothorax, are common complications of humeral fractures.
Other possibilities
include intrapulmonary haemorrhage,
diaphragmatic rupture, rib fractures and occasionally
chylothorax. A careful clinical and radiological examination should be done to check for chest inj uries.
The patient's condition should be stabilized before embarking on fracture fixation.
WARNING
Humeral fractures are frequently accompanied by chest injuries.
Fractures of the proximal metaphyseal region
Uncommon
Usually transverse and impacted
Nutritional secondary hyperparathyroidism in pups or osteosarcoma formation in adults are predisposing factors.
Additional exposure for lateral plating
Exposure of the humeral shaft is as described above, but in addition the brachia lis muscle and the radial nerve are
mobilized so that the plate can be slid beneath them on the lateral side ofthe humerus (Figure 15.17). The origin ofthe extensor carpi radialis muscle is freed from the lateral
condyle to complete exposure of the distal humerus.
WARNING
Fracture reduction and insertion of implants, especially in comminuted fractures, is not easy and the inexperienced surgeon should consider referring such cases to a specialist for treatment.
