Cubital Tunnel Syndrome Associated with Medial Elbow Ganglia and Osteoarthritis of the Elbow

Cubital Tunnel Syndrome, Associated With Synovial Chondromatosis

“…The most commonly affected site is the knee joint 3) , though it has been observed in nearly all peripheral joints including the elbow 7,9,11) , wrist, knee 3) , spinal facet joint 2,5) , hip 4,8) , and temporo-mandibular joint 1,6) .…”

“…A 62-year-old female patient suffered from numbness and resting pain in the right ring and little fingers forflexor carpi ulnaris and a medial epicondyle, but several authors reported that cubital tunnel syndrome is unusually caused by a mass compressing ulnar nerve 7) . Kato et al 7) reported that medial elbow ganglia are associated with osteoarthritis of the elbow and can also cause acute onset of cubital tunnel syndrome and the prevalence of this lesion among patients with cubital tunnel syndrome is about 3 to 19%.…”

“…Kato et al 7) reported that medial elbow ganglia are associated with osteoarthritis of the elbow and can also cause acute onset of cubital tunnel syndrome and the prevalence of this lesion among patients with cubital tunnel syndrome is about 3 to 19%. Other report have shown that the compressive ulnar neuropathy is caused by synovial chondromatosis like this report 9) .…”

Magnetic resonance imaging of the elbow

“…A number of anatomic variants can result in ulnar neuritis, including thickening or absence of the cubital tunnel retinaculum, or an accessory anconeus epitrochlearis (11,(59)(60)(61). A variety of other conditions can result in compression of the ulnar nerve within the cubital tunnel, including prior fracture, medial collateral ligament injury, posteromedial osteophytes, synovitis, or other space-occupying lesions such as ganglia (62,63). The ulnar nerve can also be compressed in other locations of the arm, including the upper arm where the nerve passes from the posterior to anterior compartment through the arcade of Struthers, a fibrous band running from the medial head of the triceps to the medial intermuscular septum (64,65).…”

A Fusiform Epineural Ganglion Encompassing the Ulnar Nerve in the Cubital Tunnel

“…Specifically, all cases had a history of trauma to the elbow or showed degenerative arthritic findings on simple radiographs. 1,2,5,6) This report presents an extremely rare case of a fusiform epineural ganglion encompassing the ulnar nerve in the cubital tunnel with no connection to the elbow joint. In addition, this case showed no evidence of arthritic changes to the elbow joint and the preoperative range of motion was within normal limits.…”
