Objective To provide anatomical basis for the operation of the transposition of partial tendon of dorsum of hand to repair metacarpophalangeal joint dislocation. Methods Morphology configuration were measured with classifying tendon of dorsum of hand into three parts on 30 sides of adult cadaver upper limb specimen. Results The lenth of the tendon of short extensor muscle of thumb is 8.2±0.8 cm, the width of tendon is 2.3±0.6 ram, 1.9±0.7 mm and 2.8±0.9 mm, the thicknesses of tendonis 1.2±0.3 ram, 0.9±0.3 mm and 8.2±0.8 mm at upside, middle and down side, The lenth of tendon of index finger of musculus extensor digitorum communis is 13.0±1.6 cm, the width of tendon is 2. 2±0.5 mm, 2.2±0.4 mm and 3.0±0.6 mm, the thicknesses of tendon is 1.4±0. 2 mm, 1. 1±0. 2 mm and 1.2±0.2 mm, The lenth of tendon of extensor muscle of index finger is 9.2±3.0 cm, the width of tendon is 3.1±0.8 ram, 2.7±0.6 mm and 3.1±1.2 mm, the thicknesses of tendon is 0.9±0.2 mm, 0. 9± 0. 2 mm and 1.0±0.2 ram. The lenth of tendon of middle finger of musculus extensor digitorum communis is 18.4± 2.3 cm, the width of tendon is 4.1±1.0 mm, 2.2±0.5 mm and 4.3±0.3 mm, the thicknesses of tendon is 1.3±0. 4 mm, 1.5 ± 0.3 mm and 1.4 ± 0.5 mm. The lenth of tendon of ring finger of musculus extensor digitorum communis is 14.1±2.4 cm, the width of tendon is 2.2±0.6 mm,1.8±0.5 mm and 4.1±1.3 ram, the thicknesses of tendon is 1.3±0.4 mm, 1.2±0. 3 mm and 1.1±0.6 mm. The lenth of tendon of little finger of musculus extensor digitorum Communis is 9.4±1.4 cm, the width of tendon is 1.5±0.4 mm, 1.2±0.4 mm and 2.9±0.7 mm, the thicknesses of tendon is 0.9±0.3 mm, 0.8±0.2 mm and 0.6±0.2 mm, The lenth of extensor digiti minimi muscle tendon is 12.1 ±2.1 cm, the width of tendon is 1.7±0.5 mm, 1.3±0. 4 mm and 3.0±0.9 mm, the thicknesses of tendon is 0.9± 0.3 mm, 0.8±0.2 mm and 0.7±0.3 mm. Conclusion The transposition of tendon of dorsum of hand has enough lenth and intensity to rebuild metacarpophalangeal joint.
