What does the Opponens Digiti Minimi muscle do?
Opponens digiti minimi extends mainly between the hamate bone, which is a carpal bone, and the fifth metacarpal bone. By acting on the carpometacarpal joint, this muscle helps with flexion, lateral rotation and opposition of the little finger. Such actions, especially the latter, are important for a strong, hand grip.
What is flexor Digiti Minimi Brevis?
Flexor digiti minimi brevis spreads from the hook of hamate bone and flexor retinaculum to the base of proximal phalanx of the little finger. The main function of this muscle is flexion of the little finger in metacarpophalangeal joint.

Is selective atrophy of the abductor digiti quinti a marker of entrapment?
The MR finding of selective atrophy of the abductor digiti quinti (ADQ) muscle has been reported as a marker of such entrapment. We performed a prospective study of consecutive patients undergoing foot and ankle MRI to determine the prevalence of ADQ atrophy and to examine the clinical symptoms of patients found to have ADQ atrophy.
Is plantar fasciitis associated with atrophy of the abductor digiti quinti?
Fatty atrophy of the abductor digiti quinti muscle is strongly associated with neuropathic alterations of the first branch of the lateral plantar nerve. The present study showed a significant association between plantar fasciitis and ankle varices with grade IV atrophy of the abductor digiti quinti …
What is muscle atrophy or muscle wasting?
Muscle Atrophy or Muscle Wasting. Muscle atrophy is the loss or decrease of muscle mass. The synonyms for it are muscle wasting, muscle loss, muscle catabolism, and muscle withering.
