Subscapularis tenotomy - the effect on exposure in cadavers

Quantification of the exposure of the glenohumeral joint from the minimally invasive to more invasive subscapularis approach to the anterior shoulder: a cadaveric study.

These authors used 10 forequarter cadaveric specimens to explore different subscapularis approaches to the glenohumeral joint. 

While they concluded that a subscapularis splitting approach allowed adequate exposure for "glenoid-based procedures", it is important to note that the cadavers did not have the typical soft tissue and bony pathology of an arthritic shoulder. This these results may not be applicable to the care of patients with shoulder arthritis.

Since failure of the glenoid component is the most common cause of total shoulder arthroplasty complications, glenoid exposure is critical to achieving the best possible reconstruction. Our approach is shown here. After surgery it is critical to care for the subscapularis.
