Shoulder Tendinopathy Induced by Statins: A Case Report and Systematic Review.

Background: Statins are essential for managing cholesterol levels but can induce musculoskeletal side effects, including tendinopathy of the shoulder. Rotator Cuff Disease (RCD) is one of the most common shoulder tendinopathy. The aim of the present study is to report a clinical case of statin-induce RCD after performing a systematic review on the subject. Materials and Methods: We performed a systematic review of the literature and report the case of a 49-year-old man with statin-induced RCD treated with a personalized individual rehabilitation project (IRP) (steroid and HA injections, mesotherapy, and therapeutic exercise) to investigate the relationship between statins and shoulder tendinopathy. The review followed PRISMA guidelines (2020 version), searching PubMed, Web of Science, and SCOPUS. Results: Out of a total of 217 articles, three cohort studies were suitable for our review. Conflicting evidence emerged regarding the association between statins and shoulder tendinopathy from the included papers. The case report describes a patient who experienced RCD after increasing atorvastatin dosage, with symptoms improving after dose reduction and a multimodal personalized IRP. Conclusions: Statins may contribute to tendon injury by altering the extracellular matrix and cell membrane integrity. While tendinopathy and statin relation is still under discussion, clinicians should monitor patients for tendinopathy and consider switching to alternative treatments in case symptoms arise. The case report demonstrated the successful management of statin-induced RCD with a multimodal personalized IRP. Further research is needed to clarify the relationship between statins and shoulder tendinopathy. Early diagnosis and appropriate personalized management are crucial for optimizing patient outcomes.
