Palpation of the lateral bands of the extensor apparatus of the fingers. Anatomy of a neglected clinical finding.

If so, palpation of the LBs could help evaluate hand conditions that impact the digits’ intrinsic muscles. To this end, the PP of the middle and ring fingers of the dominant hand of seven subjects were studied by palpation on both sides. Ultrasonography (US) was performed with a hockey-stick transducer placed on the ulnar side. Five cadaveric hands were dissected, exposing the dorsal extensor apparatus. On palpation, a firm cord was consistently felt at the PP's sides in all subjects. These cords moved widely forward on PIP flexion and backward with PIP extension. By US scanning, the cords corresponded to the LBs. However, the forward movement had only a median of 1.8 mm (range 0.7–3 mm) in the middle finger and a median of 1.1 mm (range 0.3–2.7 mm) in the ring finger compared with an estimated 5–10 mm upon palpation. Cadaveric dissection confirmed the forward movement of the LBs in PIP flexion. We concluded that the firm cords felt at the PP sides are the LBs of the extensor apparatus. We confirmed their movement with the active flexion/extension of the PIP joint. Comparing the wide palpatory and the meager US motion, a haptic illusion of motion may be present. eng Palpation of the lateral bands of the extensor apparatus of the fingers.
