title: Os supratrochlear dorsale of the elbow: a report of two cases.
abstract: The os supratrochlear dorsale, an accessory ossicle of the elbow, has rarely been described in the literature. Rather than being caused by trauma, it is subject to trauma by elbow extension with secondary chondrometaplasia, resulting symptomatology. The aim of this report is to remind readers that its presence is crucial for both diagnostic and therapeutic purposes. Arthroscopic removal may be required to relieve persistent pain, catching and limited range of motion.
