space (p. 39), and the structures passing through it (Fig. 6). 

 Stiffness of the shoulder, following reduction of dislocations, 

 may be due to the formation of adhesions between the contiguous 

 synovial surfaces of this part of the capsule. Early massage 

 and passive movement will prevent such a complication.

The Synovial Membrane lines the capsule and is attached 

 to the articular margins of the two bones. It covers, but is 

 not adherent to, the periosteum over the intra-capsular part, 

 of the neck of the humerus (intra-capsular part of diaphysis 

 and epiphyseal cartilage, in the young). Between the superior
