Exploring the anatomy of dorsal radiocarpal ligament of the wrist and its ulnar part: a cadaveric study.
The current study aimed to explore the anatomy of the dorsal radio-carpal ligament (DRC ligament) and to investigate the presence and histological structure of ulnar part of the DRC ligament.   Twenty cadaveric wrist joints were dissected and attachments of the DRC ligament and the newly described ulnar part of the DRC ligament were identified and noted. Samples of both ligaments were sent for histological examination.   The DRC ligament was identified in all 20 specimens with type I Mizuseki arrangement of fibres seen in 60% of wrists. The ulnar part of the DRC ligament was successfully identified in 18 of the 20 wrists. The histological observation of the ulnar part of the DRC ligament showed the highly uniform arrangement of collagen bundles typical of ligaments.   This study explores the anatomy of the DRC ligament and confirms the presence of the ulnar part of DRC ligament through histological analysis not undertaken in previous studies.
