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 proximalportion 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)mmand(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. Conclusion:The internal fixation of scaphoid can be designed according to the anatomical data without damaging the articular surface and blood supply.
