Abstract
We did this study in order to analyse shoulder movement. Instability was measured in the cases with abnormal instability (hypermobility) and in a normal group through Roentgenographic findings.
Materials were one hundred and eighty eight cases: 31 cases of traumatic recurrent dislocation,70 cases of loose shoulder,48 cases of “rotator interval” lesion and 39 cases of complete cuff tear. All were treated surgically. Nine hundred and thirty four normal cases were also measured as a contrast.
