1. The supracondyloid process, when present, is often associated with a tendinous band, which is attached to the medial epicondyle, and with an anomalous origin of the pronator teres.
2. The supracondyloid process can cause a syndrome characterized by pain, radiating from the shoulder to the median-nerve area of the hand. This pain is increased by pronation of the extended forearm.
3. The diagnosis is easily made by palpation, but routine anteroposterior or lateral roentgenograms may fail to show the spur, because of its position on the anteromedial aspect of the bone. An oblique view may be required.
4. Solieri and Mandruzzato have reported three cases in which relief followed resection, and one additional case of resection is reported here.
5. In resection of the bony spur, it is emphasized that removal of the periosteum of the spur and the binding fibers of the pronator teres should be done to prevent regeneration of the spur and the recurrence of symptoms.
