Median neuropathy after multiple punctures of the forearm for catheterization: A case report

Figure 1 Preoperative physical examination. A and B: Inspection of the right hand. The Tinel like sign was positive at the 2 proximal lateral digits from the wrist crease (1); C: Finger extension. Allowable without restriction; D: Finger flexion. Restriction of the index and middle fingers prevents full grip; E: Right hand perception. Numbers represent two-point discrimination test, colors represent semmes weinstein test results. There is a decreased perception in the median nerve area; F: Nerve conduction studies results of the median nerve. Compound muscle action potential was reduced and sensory nerve action potential showed no waveform appearance.
