Abstract:

Objective  To study the anatomical basis of volar dual-channel  surgical  approach  for treatment of distal radioulnar fracture.  Methods   Ten fresh adult upper limb specimens were dissected and observed. A longitudinal incision was made between the flexor carpi radialis tendon and palmaris longus tendon.  Carpal canal was bypassed from the ulnar and radial sides respectively and   the surgical field exposure of distal radioulnar fracture was observed.   Result    Maximum transverse exposed distance of radial lateral channel was (3.0±0.29) cm and maximum transverse exposed distance of ulnar lateral channel was (2.3±0.26) cm, 3 cm above the volar wrist creases. Compared with radial lateral channel, ulnar lateral channel got better exposure of the ulnar aspect of the distal radius and distal ulnar bone.   Conclusion   Volar dual-channel surgical approach of the distal radioulnar fracture, which is a safe and effective surgical methods with satisfying exposure, is worth of clinical promotion.
