Ultrasound Diagnosis of Double Crush Syndrome of the Ulnar Nerve by the Anconeus Epitrochlearis and a Ganglion.

Ulnar nerve palsy due to concomitant compression by the anconeus epitrochlearis muscle and a ganglion cyst.

Compression neuropathy of the ulnar nerve at the elbow is commonly caused by constriction at the fibrous cubital tunnel or an anatomical elbow deformity. Many uncommon causes of compression have been described, including Osborne’s band, ulnar nerve subluxation,1 anatomical confines of the cubital tunnel, elbow osteoarthritis, ganglion,2 prominent medial head of triceps,3 and an anconeus epitroc...

Anconeus Epitrochlearis Muscle Causing Ulnar Neuropathy at the Elbow: Clinical and Neurophysiological Differential Diagnosis.

Ulnar neuropathy at the elbow is the second most frequent entrapment neuropathy and is considered idiopathic in most patients. However, several anatomic variations, including the anconeus epitrochlearis muscle, have been reported to cause ulnar nerve compression. The anconeus epitrochlearis muscle is a common anatomic variation, with a prevalence of up to 34%, but the clinical diagnosis of ulna...

Ulnar neuropathy as a result of anconeus epitrochlearis.

After carpal tunnel syndrome, cubital tunnel syndrome is the second most common compression neuropathy in the upper extremity. Various sites of ulnar nerve compression at the elbow exist, with the most common being between the 2 heads of the flexor carpi ulnaris. Other potential sites include the arcade of Struthers, the space between Osborne's ligament and the medial ulnar collateral ligament,...

Anconeus epitrochlearis as a source of medial elbow pain in baseball pitchers.

Medial elbow pain is reported in 18% to 69% of baseball players aged of 9 and 19 years. This is due to the large valgus stresses focused on the medial side of the elbow during overhead activities. In overhead throwers and pitchers, pain can be attributed to valgus extension overload with resultant posteromedial impingement, overuse of the flexor-pronator musculature resulting in medial epicondy...
