1. Results: The true pattern in the palmar hypothenar area showed the pedigree character of monogenic trait in 5 families.

2. Methods The thenar and hypothenar muscles were studied in seven (14 sides) adult cadavers.

3. The frequencies of true patterns in hypothenar distal area are more than other areas.

4. Hypothenar palm of your hand or pat his arm, the lateral.

5. Results The blood of the hypothenar district of 10 specimens and 7 patients provides four sources, and the foot artery contains a special branch enter the little finger exhibition muscle.

6. Aim To observe the protective effect of femoral nerves transferred to the muscular branches of the thenar and hypothenar muscles on the hand intrinsic muscles.

7. The reflex area of the uterus on the hand is in the triangle formed by the thenar, hypothenar and wrist.

8. Results The occurrence of the TFRC td TRC. Sydney line and the ridge dissociation in hypothenar in hypophrenic children is remarkably higher than that of the normal group.

9. Objective: To study the pedigree character of the true pattern in palmar hypothenar area, and study the genetics of the true pattern in human palmar hypothenar area.

10. Objective To study the microsurgery anatomical basis of the hypothenar flap and to provide method for repairing ventral soft tissue defect of the finger through free transplantation of the flap.

11. Results: According to the course of the ulnar nerve in ulnar tunnel, it is divided into the pisihamate part, the hypothenar segment part( ), the deep palmar segment part and the terminal part.

12. This study provides new data of microvascular three dimensional architecture for the skin transplantation of the arm, forearm, thenar and hypothenar skin flaps.

13. Conclusion: The genetics of the true pattern in human palmar hypothenar area may belong to autosomal dominant inheritance.

14. There is no difference about the morphologic construction of the microvessel networks between the left and the right hand, and between thenar and hypothenar.

15. With the improved harvest method, the flaps were used to repair skin defects in 18 cases, of which included palm, dorsum, thenar, hypothenar and the thumb.
