Cubital Tunnel Syndrome, Associated With Synovial Chondromatosis

Entrapment of the ulnar nerve in cubital tunnel by free intra-articular body—a case report

“…Cases like this, in which a free intra-articular body distended the elbow joint capsule, causing compression of the nerve by cubital tunnel narrowing, are uncommon. The origin of the free intra-articular body could be secondary to a type of chondromatosis inflammatory process, as described by Kim et al and Mueller et al,7, 11 or an osteoarthrosis, like the present case, with a clear connection between the fracture of the radial head and the subsequent outbreak of free intra-articular bodies. Within the etiologic diagnosis, it was considered that the entrapment of the ulnar nerve was caused by bone spicules secondary to osteoarthrosis, but it was discarded with radiologic and surgical findings of free intra-articular bodies.…”

Posterior interosseous nerve palsy caused by synovial osteochondromatosis of the elbow analyzed by three-dimensional reconstruction: a case report

“…Peripheral nerve palsy due to synovial osteochondromatosis of the elbow joint is rare, and there are some case reports of palsy of the PIN [3–5, 7], ulnar nerve [6, 8–13], and median nerve [14]. …”

Ulnar nerve palsy caused by synovial protrusion in synovial chondromatosis of the elbow: a case report and literature review

“…Then, we excluded three articles because those were not published in English and, finally, seven cases about ulnar nerve palsy associated with SC were reviewed (Table 1). [5][6][7][8][9][10][11] In these cases, the nerve compression was not confirmed until the time of surgical exploration. Our patient had protrusion of the capsule to the cubital tunnel as an obvious space-occupying lesion on the preoperative MRI.…”
