Injury
-
Three cases with injury of the axillary artery and brachial plexus complicating a displaced proximal fracture of the humerus are presented. In two patients the arterial injury was not recognized on admission. ⋯ In two of the cases, the arterial injury may have been caused by an attempt at closed reduction of the fracture. The possibility of axillary arterial injury should be considered in proximal fractures of the humerus with severe medial displacement of the shaft of the humerus.

This paper reports the results of treatment of 17 patients with fractures of the shaft of the humerus accompanied by paralysis of the radial nerve in a series of 111 patients with fractures of the shaft of the humerus. In early operative explorations in 14 cases the radial nerve appeared undamaged in 13 cases. ⋯ The high incidence of undamaged nerves at exploration suggests that a conservative approach by collar and cuff or Sarmiento bracing is justified in such cases of fractures of the shaft of the humerus. Paralysis of the radial nerve associated with fractures of the shaft of the humerus is, in our opinion, not an indication for early operative treatment.
