摘      要：Background：Hand injuries are very common in sports,such as skiing and ball *** of the major reasons causing hand and finger deformity is due to ligament and tendon *** aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging （MRI） can demonstrate the complex anatomy of the fingers and thumb,especially the tendons and ligaments,and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport ***：Sixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers.A total of 20 healthy volunteers＇ hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this *** subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression （PD FS） in axial,coronal,and sagittal plane,***,all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw （six in coronal plane,six in sagittal plane,and four in axial plane）.The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament （UCL） at the metacarpal phalangeal joint （MCPJ） of thumb between 20 healthy volunteers and 44 patients （confirmed by surgery） were ***：The normal ligaments and tendons in 16 cadaveric hands and 20 volunteers＇ hands showed uniform low-signal intensity on all the sequences of the *** 44 patients with tendinous and ligamentous injuries in the fingers or thumb,12 cases with UCL injury at MCPJ of the thumb （Stener lesion =8 and non-Stener lesion=4）,6 cases with the central slip injury,12 cases with terminal tendon injury,and 14 cases with flexor digitorum profundus *** ligaments and tendons disruption manifested as increased signal intensity and poor definition,discontinuity,and heterogeneous signal intensity of the involved ligaments and ***：Spo
