“…Those differences are most likely due to differences in dissection technique. Nimura et al () found similar discrepancies and commented that the difference in degree to which the capsule was dissected from each tendon would account for the reported variations.…”

“…Ruotulo et al (2004) reported supraspinatus’ width as 12.1 mm. Nimura et al () measured the supraspinatus maximal width as 7.6 mm, and the infraspinatus maximal width as 9.7 mm (Table ).…”

“…Precise anatomical knowledge of the supraspinatus and infraspinatus muscles' humeral footprints is essential for advancement of rotator cuff repair, with the development of techniques such as double row repair coming on the basis of sound anatomical knowledge (Lo and Burkhart, 2003 ;Millett et al, 2004). The literature is equivocal about the exact morphology of the insertion of the supraspinatus and infraspinatus muscles (Dugas et al, 2002;Curtis et al, 2006;Mochizuki et al, 2008;Nimura et al, 2012).…”

In shoulder surgery, a precise understanding of anatomical relationships is required for accurate reconstruction. Reports in recent literature have challenged the traditional definitions of the humeral footprints of the supraspinatus and infraspinatus tendons. This study aims to precisely delineate these footprints. The rotator cuffs of 54 shoulders from 27 Australian Caucasoid donor cadavers were examined. The tendinous portions were dissected down to their region/footprint of attachment upon the humerus. Measurements of those footprints, upon the greater and lesser tuberosities, were made. Those measurements were statistically analyzed for any association with age, sex, height, or side. Twenty-seven cadavers had an average age at death of 74.9 (± 12.8), 56% were male, average height was 168 (± 8.6) cm. Due to premorbid fracture, or degeneration, 11 shoulders were excluded. The footprint of the supraspinatus was triangular, with a medial, anteroposterior length of 20.4 ± 4.2 mm. Its lateral anteroposterior length was 6.3 ± 1.6 mm and its maximal mediolateral width was 6.6 ± 2.7 mm. Its calculated area was 122.0 ± 66.6 mm(2). The footprint of the infraspinatus was trapezoidal, with a medial anteroposterior length 22.6 ± 3.0 mm. Its lateral anteroposterior length was 25.4 ± 3.3mm and its maximal mediolateral width was 12.0 ± 2.7 mm. Its calculated area was 294.9 ± 74.1 mm(2). There was no statistical correlation between size of the footprint and age, sex, side, or height. The humeral footprints of the supraspinatus and infraspinatus tendons upon the greater tuberosity were distinct. The lateral border of the infraspinatus' humeral attachment extended much farther anteriorly upon the highest facet of the greater tuberosity than in traditional descriptions.

“…96 As a result, it is often disrupted when complete tears of the supraspinatus or infraspinatus occur. 80 A recent biomechanical study determined that superior capsular defects led to increased glenohumeral translation in all directions, particularly with superior translation at 5 and 30 of abduction.…”

“…The anterior capsule serves to maintain glenohumeral stability anteriorly, whereas posterior capsule plays an important role with posterior stability [8,91]. The superior capsule attaches to a significant portion of the greater tuberosity, with an anatomic study indicating a range between 30% and 61% of total surface area [92]. As a result, it is often disrupted when complete tears of the supraspinatus or infraspinatus occur [41].…”

Management of massive tears of the rotator cuff tears is one of the most difficult problems an upper limb surgeon encounters. Patients with similar tears can present with minimal discomfort through to a flail shoulder. There are a bewildering number of options available, many with published outcomes not always borne out in clinical practise. These range from rehabilitation, simple arthroscopic surgery, attempts at repair, complex tendon transfers and ultimately a reverse total shoulder replacement. More recently further options of patch augmentation and balloon arthroplasty have been added. This paper attempts to provide a critical assessment of the evidence available.
