ARTICULATED RADIAL HEAD REPLACEMENT AND ELBOW RELEASE FOR POST HEAD-INJURY HETEROTOPIC OSSIFICATION

This is a case report of the release of an elbow ankylosed by post-hea d-injury heterotopic ossification. An extensive bony resection and sof t-tissue release was required, At surgery a pathological, osteoporotic fracture of the radial head was found that could not be preserved and thus was removed. In its place an articulated ''floating radial head prosthesis'' was used that allowed immediate rehabilitation and avoide d the need for temporary joint distraction or stabilization. The initi al excellent function achieved has been maintained, at a >3-year follo w-up and without the complications experienced with silicone radial he ad prostheses.
