Early diagnosis of ulnar impaction syndrome / 中华创伤骨科杂志

Objective To explore early diagnostic methods for ulnar impaction syndrome on the basis of suggested criteria.Methods From December 1998 to December 2004,123 cases complained of ulnar pain.They were checked and diagnosed according to the criteria of Yu-dong Gu,and especially,the results of wrist MRL Forty-eight of them were diagnosed as ulnar impactinn syndrome.A retrospective study was done to analyze the char- acteristies of X-ray and MRI in examining ulnar impaction syndrome,clinical symptoms of the wrist,and the association between Chun & Palmer's scoring systems and imaging manifestations.Results Most of the cases of ulnar impaction syndrome had positive lunar variance (68.8%).Carpal avascular necrosis was found in about 27.1% of the cases through X-ray examination of the wrist,64.7% of whom were lunar osteonecrosis.Abnormal changes in signal intensity occurred in the MRI findings of the syndrome cases.The carpal necrosis was always located at the ulnar side of lunare or (and) at the waist and bottom of triquetrum.There was a close relationship between clinical symptoms and Chun & Palmer's grading systems and carpal imaging,MRI in particular Conclusion Early diagnosis of ulnar impaction syndrome can be made easily on the basis of deep understanding of the syndrome,clinical symptoms,and findings of imaging,especially MRI.
