Anatomic measurement of wrist scaphoid and its clinical significance.
OBJECTIVE
To provide anatomical basis for the internal fixation of scaphoid fractures.


METHODS
The shape and vascular lake of 48 dry scaphoids and 36 wet scaphoids were observed.


RESULTS
The data of dry bone group and wet bone group were as follows: the height of scaphoid tubercle were (11.28+/-0.94) mm and (10.35+/-1.54) mm; the thickness of scapoid waist were (12.02+/-1.90) mm and (11.21+/-1.20) mm; the width of scapoid waist were (10.59+/-1.11) mm and (11.34+/-1.47) mm; the minimal thickness of the body of scapoid were (6.51+/-1.22) mm and (8.54+/-1.07) mm; the axis length of scapoid were (25.68+/-2.21) mm and (26.50+/-2.56) mm; the width of epicondyle of scaphoid of distal portion, waist and proximal portion were (6.50+/-1.06) mm, (5.14+/-1.01) mm, (4.42+/-1.16) mm and (6.64+/-1.18) mm, (6.01+/-0.75) mm and (5.71+/-0.78) mm, respestively. The main blood vessels came from the dorsal and the radial of wrist and passed through the whole scaphoid along the crest of scaphoid.


CONCLUSIONS
The internal fixation of scaphoid can be designed according to the anatomical data without damaging the articular surface and blood supply.
