Anatomy study of carpal ligaments

Objective To investigate the anatomical properties of carpal ligaments.Methods Thirty-four cadaver specimens of adult wrists were prepared and dissected for the study,of which 32 were fixed in formalin,and another 2 were fresh.The observation included the origin,insertion,course and spatial relationship.The measurement included length,middle segment width and thickness of each carpal ligament.Results Carpal ligaments included 3 parts: palmer,dorsal and interosseous parts.Radially the palmer and dorsal wrist ligaments were long and wide.The palmer ligaments were generally stronger and more in number than the dorsal ligaments.The interosseous ligaments were short and thick.Conclusion Adjacent wrist ligaments oriented in many V-shaped configurations,which maintain the steadiness of wrist and carpal bones.
