title: Intramedullary nailing of humeral shaft fractures.
abstract: The development of interlocking humeral nail systems has greatly broadened the indications for nailing of humeral shaft fracture. Rotational control is better than with earlier nail systems, and most nails have an oblong distal hole that allows axial loading of the fracture site with muscle contraction. When nailing is done with closed technique, loss of the fracture hematoma and periosteal stripping are avoided. Even when open reduction is required, periosteal stripping can be kept to a minimum. Surgical wounds are smaller, even when open reduction is necessary, and when closed nailing is done, bone grafting is unnecessary. Intramedullary nails are ideal for segmental fractures, pathologic fractures, and fractures in osteopenic bone. Because the arm usually is not a weight-bearing extremity, hardware failure is rare and union rates are equivalent to those of compression plate and screw fixation. Compression plates and external fixation certainly have their place for some fracture patterns and for severe wounds that are unsuitable for intramedullary nailing. The surgeon should be well versed in all three techniques and should be able to rapidly choose among these, depending upon the fracture pattern, skin wound, associated injuries, and overall condition of the patient.
