Observational analysis revealed significant pain reductions in SAPS patients after PM tenotomy and neurolysis, suggesting unique pathophysiology.
Key Points
Pain decreased significantly from a median of 8 to 2 in SAPS patients after treatment, and shoulder range of motion improved from 90 to 180 degrees.
In a cohort of 140 SAPS patients, 100% tested positive for impingement before treatment, dropping to 11% post-procedure within six months.
Patients meeting Human Disharmony Loop criteria underwent combined PM tenotomy and neurolysis, with some receiving additional distal neurolysis as needed.
These results highlight that addressing the anatomic origin may improve outcomes for chronic shoulder pain associated with subacromial impingement.
