The Acromio- clavicular joint (AC J) is a synovial joint consisting of an intrinsic fibrocartilaginous disk between the opposing articular surfaces which degenerates and usually disintegrates by the age of 40 years. The aim of the study was to measure the normal Acromio- clavicular Joint width sonographically among Sudanese population. The study was conducted on a seventy seven Sudanese population includes 63.6% of males and 36.4% of females of the sample, scanned by ultrasound machine with the participant sitting on a rotating stool and the forearm or hand resting in a supinated position on the thigh, palm up, Begin the examination by facing the participant then place the transducer in the coronal plane over the shoulder to examine the AC J.. There was a correlation between AC J space and volunteer’s sex and age; where there was no significant correlation between AC J and the volunteer’s body weight and height. The best correlation was between the ACJ and volunteer’s age followed by the ACJ and volunteer’s sex. The mean standard of AC J was 4.9, therefore we should take the AC J measurement in addition to the essential Rotator cuff measurements.
