Partial Thickness Rotator Cuff Tears: Current Concepts

Figure 1

Illustration showing the two different insertional descriptions of the humeral insertions of the supraspinatus (SSP-I) and infraspinatus (ISP-I). (a) The generally accepted concept of the supraspinatus inserting into the highest impression and the infraspinatus inserting into the middle impression of the greater tuberosity (GT). (b) An alternative illustration, in which the insertion of the infraspinatus occupies the majority of the GT, covering both the middle and half of the highest impression of the GT. Also noted is the additional attachment of the supraspinatus to the most superior aspect of the lesser tuberosity (LT). HH = humeral head (adapted and reprinted from [6] with permission).
