Abstract:The suprascapular nerve arises from the upper trunk (Erb's point) of the brachial plexus in the posterior triangle of the neck.This research was conducted to study the anatomy of the suprascapular nerve in the scapular region and its relation to both suprascapular and spinoglenoid notches. This data is very important in suprascapular nerve block and suprascapular nerve surgical decompression. Dissection of 20 scapular regions of 10 formalin preserved male cadavers was done. Also thirty three adult patients; 26 males and 7 females suffering from vague shoulder pain subjected to suprascapular nerve surgical decompression. In all cadaveric specimens, careful dissection and anatomical study of suprascapular nerve regarding its course, distribution and relations was carried out. Origin of the nerve was demonstrated from upper trunk of the brachial plexus. Passage of the nerve through a narrow medial compartment of supraglenoid canal in all cases has been identified. Measurements of two important diameters relevant to suprascapular notch were also reported. The transverse scapular ligament was identified to be of uniform thickness. In the clinical study of all cases with suprascapular nerve entrapment regardless its etiology whether idiopathic or not, conservative therapy by means of the exercise was of limited value especially for the motor affection. All of the cases were subjected to surgical maneuverer to decompress the nerve. It is concluded that the anatomical findings allow better choice of the surgical procedure, more precise surgical dissection, better results and fewer complications.

“…In einer morphometrischen Studie ermittelten Ruotolo et al [33] eine durchschnittliche anteroposteriore Ausdehnung des Supraspinatussehnen-Footprints von 25 mm, die durchschnittliche Stärke der Supraspinatussehne betrugje nach Lokalisation der Messung -zwischen 11,6 mm im anterioren Anteil der Supraspinatussehne unmittelbar posterior des Rotatorenintervalls, 12,1 mm im mittleren Sehnenbereich und 12,0 mm im posterioren Anteil der Supraspinatus-unmittelbar neben der Infraspinatussehne. Die Distanz zwischen der Knorpel-KnochenGrenze und der Supraspinatussehnen-Insertion lag bei durchschnittlich 1,7 mm.…”

“…Die Distanz zwischen der Knorpel-KnochenGrenze und der Supraspinatussehnen-Insertion lag bei durchschnittlich 1,7 mm. Somit entspricht eine Ausdehnung von mehr als 7 mm einem exponiertem Footprint lateral der Knorpel-Knochen-Grenze bei einer artikulärseitigen Supraspinatussehnen-Partialruptur (PASTA-Läsion) einer signifikanten SupraspinatussehnenPartialruptur von mindestens 50% des Sehnendurchmessers [33].

“…In addition, the rabbit subscapularis footprint has been found to have dimensions of a mean 6.8 mm in the superior-inferior direction and 2.5 mm in the medial lateral direction, approximately 1 . 4 of the size of the human supraspinatus footprint, which allows for recreation of human rotator cuff repair techniques in this model [20,40].…”

Background Recent evidence suggests that the rabbit subscapularis tendon may be anatomically, biomechanically, and histologically suitable to study rotator cuff pathology and repair. However, biomechanical comparisons of rotator cuff repairs in this model have not been evaluated and compared to those in human cadaveric specimens. Questions/purposes We quantified the biomechanical properties of the repaired rabbit subscapularis tendon after (1) single-row, (2) double-row, and (3) transosseousequivalent rotator cuff repair techniques and compared the ratios of repairs to previously published data for human repairs.Methods Tensile testing was performed on 21 New Zealand White rabbit subscapularis tendon-humerus complexes for single-row repair, double-row repair, and transosseous-equivalent repair (n = 7 for each group). Video digitizing software was used to quantify deformation. Load elongation data were then used to quantify structural properties. We compared the ratios of rotator cuff repairs for the rabbit data to data from human supraspinatus repair studies previously performed in our laboratory. For our primary end points (linear stiffness, yield load, ultimate load, and energy absorbed to failure), with the numbers available, our statistical power to detect a clinically important difference (defined as 15%) was 85%. Results The ratios of single-row/double-row repair were 0.72, 0.73, 0.71, and 0.66 for human supraspinatus and 0.77, 0.74, 0.79, and 0.89 for rabbit subscapularis repair for linear stiffness, yield load, ultimate load, and energy absorbed to failure, respectively. The ratios of double-row/transosseousequivalent repair were 1.0, 0.86, 0.70, and 0.41 for human supraspinatus and 1.22, 0.85, 0.76, and 0.60 for rabbit subscapularis for linear stiffness, yield load, ultimate load, and energy absorbed to failure, respectively. There were no differences comparing rabbit to human repair ratios for any parameter (p [ 0.09 for all comparisons). Conclusions Subscapularis repairs in the rabbit at Time 0 result in comparable ratios to human supraspinatus repairs. Clinical Relevance The biomechanical similarities between the different types of rotator cuff repair in the rabbit subscapularis and human supraspinatus at Time 0 provide more evidence that the rabbit subscapularis may be an appropriate model to study rotator cuff repairs.
