				        	Objective  To  improve the diagnosing level of lunate and perilunate dislocation through analysing X-ray finding and causes of missing diagnosis.Methods  16 cases of lunate and perilunate dislocation missed diagnosis were analysed.Results  In 16 cases,there were 3 cases of ventral lunate dislocation,2 cases of trans-scaphoid ventral lunate dislocation,6 cases of dorsal perilunate lunate dislocation,3 cases of trans-scaphoid dorsal perilunate lunate dislocation and 2 cases of atypical dorsal perilunate lunate dislocation.6 cases were missed in diagnosis(37.5%).Conclusion  Knowing well the normal X-ray sign of wrist,mastering the X-ray characteristic of each types of dislocation and fracture,is the linchpin of reducing missing diagnosis.
