Achieving Bone Healing Non-Operatively in Humeral Fractures in Two Patients with Risk Factors for Nonunion Utilizing a Specialized Orthosis.

We report the treatment of two patient with humeral fractures with one or more risk factors for nonunion. The first patient was elderly with a previously diagnosed central nervous sys-tem injury. The second elderly patient previously sustained a cerebral vascular accident affecting the fractured arm. The fracture was oblique in the proximal third of the humerus. We achieved bone healing non-operatively utilizing a spe-cialized plastic orthosis that included a deforming element made of dense foam. This device asymmetrically increases the soft tissue pressure around the fracture.
