compression at the elbow and heterotopic ossification: a report of five cases.
The ulnar nerve
was not rofutinely exposed, dissected, or transposed with this approach.

in posttraumatic varus deformity of the elbow," Archivio "Putti" di Chirurgia degli Organi di Movimento, vol.
There are 5 anatomic sites of ulnar nerve
compromise at the elbow: (1) intermuscular (IM) septum of the distal arm (including the Areade of Struthers, medial IM septum, hypertrophy of medial head of triceps brachii, and snapping of medial head triceps brachii); (2) medial epicondylc secondary to a valgus deformity of the bone; (3) epicondylar groove (lesions within and outside of the groove and subluxation or dislocation of the nerve); (4) cubital tunnel (due to a thickened Osborne's ligament, a fibrous fascia running between the humeral and ulnar heads to the FCU) or as the nerve passes through the proximal edge of the FCU; and (5) as the ulnar nerve
exits through the FCU.
When the characteristics of the sensory block of ulnar nerve
were considered, it was found that the suficient block level was reached at the 9th minute in the G1group and 3rd minute in the G2 group.
MRI of the elbow was also performed, which showed no abnormalities that affected signal intensity or thickness of the ulnar nerve
at the elbow segment.
In 1 case open reduction was essential and ulnar nerve
was released 2 months after trauma and in 1 case 1 month after fracture median nerve release was done.
(4) Also due to the risk of worsening the neurological deficit, a biopsy cannot be performed on nerves having a motor component, such as the ulnar nerve
. (5) Clinical assessment of the functional impairment of peripheral nerves may be inadequate and inaccurate as clinical evidence of neuropathy may appear late even in the presence of nerve damage.
