Anatomic measurement of wrist scaphoid and its clinical significance / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To provide anatomical basis for the internal fixation of scaphoid fractures.</p><p><b>METHODS</b>The shape and vascular lake of 48 dry scaphoids and 36 wet scaphoids were observed.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>The internal fixation of scaphoid can be designed according to the anatomical data without damaging the articular surface and blood supply.</p>
