(1) The study was made about the extensor digiti minimi muscle by using 132 upper extremities in 66 adult cadavers (49male, 17 female). The muscles were classified into 5 types.

(2) The most ligaments of pedis and digiti pedis can not be identified.

(3) The origin and course of the nervus abductor digiti minimi pedis and the numbers and distribution of its sensory branches were observed on 40 sides of adult cadavers.

(4) It damaged all the soft tissue arosed from fractures medially and laterally, included adductor hallucis, quadratus plantae, flexor digitorum brevis and abductor digiti minimi as well.

(5) Reconstruction of extensor digitorum tendon to little finger are effective methods to prevent or treat handicapped little extension digiti tendon transposition.

(6) Objective: To study the morphological anatomy of little finger extensors to prevent handicapped extension of little finger after extensor digiti minimi tendon transposition.

(7) Conclusion We found that the fascial arch of the opponens digiti minimi can compress the deep branch of the ulnar nerve causing motor deficit of the intrinsic muscles of hands.

(8) The deep palmar arch, besides the traditional(view-point)(/digiti.html), also consists of the branches of the redial artery and the ulnaris digiti minimi artery.

(9) CSP onset latency was inversely correlated with JOA score and N13 amplitude, and was positively correlated with central motor conduction time to abductor digiti minimi.

(10) Most of the ulnar ship of extensor digitorum tendon to little finger and extensor digiti tendon have intertendinous connections 93.4%(54/60).
