These (Watson-Jones undoubtedly 1955) though even not entirely reliable. The causes of failed healing of the glenoid labrum are unknown. In one experiment in a monkey (Scougall 1957) the glenoid labrum healed rapidly after its detachment posteriorly. The occurrence of tendinous cuff defects in five patients following acute dislocation is not surprising. Their diagnosis was undoubtedly helped by the arthrograph-especially in this is probably one patient with in this series as that opinion finding a circumflex there was arthrography palsy as well as a tendinous initial arthrograph. These is a valuable of a symptomless which no rupture was confirmed aid in the exact of the at operation, cuff together in one with cuff lesion, which findings support diagnosis of the ofthis eight five ruptures cases is not reported Kessel’s (1950) lesion. The unexpected of recurrent in twenty-seven dislocation, acute dislocations, happens more often than is suspected. It seems that when a tear is confined to the supraspinatus it causes only trivial disability, and that rupture of the greater part of the cuff is needed to produce characteristic clinical evidence of tendinous cuff tear.
