Preoperative computer-assisted design templating of complex articular olecranon osteotomy: case report.

Preoperative 3-dimensional modeling methods are commonly used in orthopedic surgery but there have been limited reports of their use for planning upper extremity surgery. In this report, we describe a case of a malunited olecranon fracture and its management using custom preoperative computed tomographic templating and mechanical modeling. One year after surgery, the patient demonstrated nearly full painless restoration of function and motion.
