The authors concluded that age modulates absolute but not relative risk and should be integrated into slope-based risk stratification.

Does suprascapular nerve release improve healing after repair of chronic massive rotator cuff tears? Zeng and colleagues created a chronic massive rotator cuff tear in rats by transecting the supraspinatus and infraspinatus.

At four weeks, nerve staining showed suprascapular nerve entrapment in seven of ten shoulders.

The remaining rats were randomized to tendon repair alone or tendon repair with suprascapular nerve release.

At eight weeks, the nerve release group had a higher maximum load to failure, about thirty-five versus twenty-seven newtons.

Stiffness did not differ.

Histologic healing scores were also significantly better at both four and eight weeks, with more organized collagen, fibrocartilage regeneration, and nerve regrowth.

The authors concluded that suprascapular nerve release improved healing in this animal model, which may support its use during clinical treatment of massive cuff repairs, although further clinical studies are needed.
