Fig. 8. Extensor tendons of the fingers and thumb. A. EDCV tendon comes off EDCIV tendon. The proper tendon sheath of EDM is seen. EIP tendon is not seen. Connexus intertendineus is not seen between EDCII and III, III and IV tendons; B. A thin and short fibrous band (a white arrow) is seen between the distal portion of EDCV and EDCIV tendons at MP joint level; C. APL tendon attaches to the radial part of the 1st metacarpal base. A thin tendinous slip of its ulnar margin extends more distally and attaches to the proximal phalanx (a thick white arrow).
