Open Excision of Olecranon Melorheostosis to Relieve Elbow Extension Block.

We report a 34-year-old man who presented with hyperostosis of his right elbow associated with an inability to fully extend his elbow. The radiographic assessment revealed a classical dripping candle wax appearance of his proximal ulna suggestive of melorheostosis. Computed tomography was performed to identify the impingement point and aid in surgical planning. A targeted open excision biopsy via a Boyd incision was performed to excise the exophytic component that was causing the functional block. After surgery, he achieved full elbow extension and was able to return to his usual activity.
