Association Between Age, Gender, HbA1c Level, Fasting Plasma Glucose Level, and the Ultrasonographic Findings in Patients With Shoulder Tendinosis

Objective: The aim of this study was to investigate the association of age, gender, HbA1c level, fasting plasma glucose level, and ultrasonographic findings in patients with shoulder tendinosis.

Methods: Patients with tendinosis (n=178) in the biceps brachii and/or supraspinatus tendon and healthy controls (n=181) were included. The demographic and clinical characteristics were recorded. Two blinded radiologists performed the ultrasonographic evaluation on the shoulders bilaterally. Also, HbA1c and fasting blood glucose levels were measured.

Results: In the tendinosis group, 54.7% of the participants were females and 37.1% of participants were males (P=.002). The number of participants over the age of 50 years was found to be increased in the tendinosis group than in the control group (P=.004). The number of patients with HbA1c levels between 5.7 and 6.4 was found to be increased in the tendinosis group (P=.014). Bilateral biceps and supraspinatus tendon thicknesses were significantly increased in the tendinosis group over 50 years old (P < .05). Right and left biceps tendon calcifications were found to be increased in those over 50 years old in the tendinosis group (P=.011 and P=.027, respectively). In the tendinosis group, right and left supraspinatus tendon calcifications were found to be increased in those over 50 years old (P=.009 and P=.013, respectively).

Conclusions: This study shows that being female and over 50 years old and having HbA1c levels between 5.7 and 6.4 increased the development of tendinosis susceptibility.
