flexor
ulnar de carpo (FUC), se observo al nervio
ulnar (NU) emergiendo del canal
ulnar, adosado al epicondilo medial del humero (EPM) relacionado con la arteria recurrente
ulnar anterior (Fig.
The first case presented with a left eye lagophthalmos, bilateral enlargement of the great auricular,
ulnar, median and radial cutaneous nerves.
An intact UCL will appear as a continuous echolucent convex structure along the
ulnar aspect of the thumb.
On applying t-test, the assumption of equal variances was violated in cases as shown by Levene's test for the following variables: NCV (median and
ulnar nerve) and amplitude (sural nerve).
On the pressure provocation test, the examiner placed his second and third fingers on the
ulnar nerve immediately proximal to the cubital tunnel, and exerted pressure for 30 to 60 seconds, with the subject's elbow flexed to about 20[degrees] and the forearm supinated (1,9,10).
However, both median and
ulnar distal latencies rise by similar degrees with increasing age, and both velocities fall to a similar degree.
Ultrasonographic evaluation of the
ulnar nerve throughout the right upper extremity (starting from the axilla until the wrist) was done using a linear array probe (7-12 MHz Logiq P5a).
The larger
ulnar and smaller humeral heads comprising the FCUM are both able to affect independently with one being confined for wrist flexion and
ulnar deviation strength while the other is for tendon transfer or soft tissue coverage of the region (10, 11).
According to their report, keeping the proximal margin of the flap to the distal of the
ulnar styloid process provides the maximum safety margin for flap elevation.
Presenting symptoms range from numbness and tingling in the
ulnar nerve distribution, often accompanied by weakness of the grip, to clawed fingers and occasionally severe intrinsic wasting.[3] If adequate conservative nonsurgical treatment fails to relieve progressive symptoms and dysfunction, surgical decompression is indicated, typically involving either superficial approaches ( in situ decompression and anterior subcutaneous transposition) or deep approaches (medial epicondylectomy or anterior sub- or intramuscular transposition).[7],[8],[9],[10],[11],[12],[13]
In the evaluation, after 4 years of follow-up, partial clinical deformity correction, remission of symptoms of
ulnar nerve irritation, and complete range of motion were achieved.
The
ulnar nerve is comprised of the anterior primary rami of the C8 and T1 nerve roots.
