Origin site, meshed with the abductor digiti minimi muscle. Muscle dimensions in situ were, 6.0 cm long, 2.0 cm wide and 1.0 cm thick.
A third, muscular and most ulnar insertion crossed over the ulnar neurovascular bundle and joined the normal abductor digiti minimi muscle (Fig.
In the second case, a triple insertion was observed, fusing with palmar aponeurosis, flexor retinaculum and abductor digiti minimi muscle, from radial to ulnar.
The compound muscle action potential (CMAR) was recorded from the abductor digiti minimi muscle
. Latencies were calculated from the beginning of the stimulation to the beginning of the CMAR and amplitudes were calculated from the middle line to the negative peak.

Morphologic Aspects of Abductor digiti minimi Muscle in the Hand
SUMMARY: The Abductor digiti minimi muscle, and the other hypotenar muscles, frequently presents anatomical variations.
In the myographic examination, the deltoid and abductor digiti minimi muscles
from the upper extremity and vastus lateralis and gastrocnemius muscles from the lower extremity were examined.
