Abstract: Ulna impingement syndrome is the main cause of wrist ulnar pain.It is caused by repeated impingement between the ulnar bone,triangular fibrocartilage complex,lunate bone and triangular bone,resulting in long-term overload of the ulnar side of wrist,affecting local blood supply and joint lubrication fluid nutrition disorders,and finally causing a series of pathological changes and clinical symptoms of joint degenerative diseases.The main clinical manifestations are pain on the ulnar side of the wrist,which gradually aggravated with repeated strong grasping activities,forearm pronation or ulnar deviation of the wrist.At present,the diagnosis of ulna impingement syndrome mainly depends on the symptoms,physical examination,imaging examination and wrist arthroscopy.Conservative treatment can be selected for ulnar impaction syndrome,but the effect is often poor.Therefore,surgery is still the main treatment.The surgical methods mainly include ulna shortening osteotomy,Wafer,Darrach and Sauvé-Kapandji,and the former two are the most commonly used.This article reviews the progress of diagnosis and treatment of ulna impingement syndrome.
