It is caused by the compression of the median nerve at the wrist, more precisely at the carpal tunnel. Based on our results, we feel the apex of the Cup of Diogenes is a consistent, fixed anatomical marker for the distal extent of the transverse carpal ligament, marking a safe zone in the palm for surgical planning of incisions.

To relieve the compression and resulting symptoms, partial or complete surgical division of the flexor retinaculum, a procedure called Carpal Tunnel Release CTRmay be necessary. Palmaris longus passes in front of the flexor retinaculum to become continuous with palmar aponeurosis.
mark the incision at the intersection of the Kaplan cardinal line and the radial border of the fourth ray ending at the wrist crease.
Kaplan's cardinal line is a guideline for locating the recurrent motor branch of the median nerve. Recurrent.
Results In all specimens, the ulnar nerve was ulnar to this the apex of the Cup of Diogenes, while the median nerve was radial. Median and ulnar nerve examination consisted in pinprick sensibility examination, two point discrimination, motor function of abductor policis brevis muscle, and motor function of ulnar nerve innervated muscles.

|Mini-open blind procedure versus limited open technique for carpal tunnel release: a month follow-up study. The tip can be felt by palpation under the skin and agreement with the formerly identified topographical landmarks is sought. The upper tip of the scissors runs in the dissected supraligamentar space.
The procedure is conducted in the surgical theater, under locorregional anesthesia with Bier technique, in an outpatient clinic basis. Anatomical landmarks to the superficial and deep palmar arches.
made in the distal part of the flexor retinaculum, starting from Kaplan's cardinal line. We feel the original description of Kaplan's cardinal line provides a more accurate Keywords Kaplan's cardinal line, Carpal tunnel, Superficial palmar arch. Kaplan cardinal line has been associated as a landmark for the motor branch of the median nerve, superficial and deep palmar arch, and distal.
Clinical treatment, with medication, physiotherapy, splinting or local infiltration can be considered initially, but surgical intervention is indicated in more advanced cases, and when there is no response to adequate clinical treatment 1.
Some complications such as pillar pain, tender scars and delayed return to work were associated to those techniques Incision placement for carpal tunnel release is debated. However, these minimally invasive incisions have been shown to have a higher risk of complications related to injury of the superficial palmar arch, ulnar nerve, and wound complications [ 6 ].
J Clin Epidemiol. The "slopes" that occur because of the difference in ligament thickness in each portion can mislead the cannula trajectory, leading to incomplete or partial opening and consequent failure to improve symptoms.
