In casesnot open to nerve suture Tubby x has suggested and successfully prac-tised the ingenious operation of substituting a portion of the pectoralismajor muscle, which is dissected from its humeral implantation, splitup, and inserted into the digitation of the serratus. The suprascapular nerve arises from the fifth and sixth cervi-cal nerves. It may suffer alone in shoulder dislocations. The supra-and infraspinati are paralyzed and the scapula becomes subcutaneousby their atrophy.
