Objective: This study aims to detect subclinical lower limb enthesitis in type 2 DM by musculoskeletal ultrasonography & its relation to poor glycemic control & disease duration. Methods This study was carried out on 80 persons selected from those attending the outpatient clinics of internal medicine department of Al-azhar university hospital, Assuit. From November 2017 till May 2018. The persons were divided into two groups: Group (A): forty diabetic patients diagnosed according to ADA diagnostic criteria (13 males and 27 females); with age ranges from 20 to 67 years. Group (B): Forty apparent healthy volunteers as a control group (16 male and 24 female) age & sex matched used as a control group. Results: About 67.5% of patients were females & 32.5% of the patients were males. About 42.5% of patients had disease duration of 3-5 years, 37.5% of patients had disease duration of 5-10 years, 10% of patients had disease duration of 10-20 years, 5% of patients had disease duration of >20 years. About 15% of patients had BMI (18.5-24.9), 57.5% of patients had BMI (25-29.9), 27.5% of patients had BMI (>30).In this study There: There is a statistically significant difference between age and Ultrasound findings p. value <0.05 There is no significant difference between gender and Ultrasound findings. There is a statistically significant difference between disease duration and Ultrasound findings p. value<0.05. Conclusion Musculoskeletal Ultrasonography is a suitable and reliable method for examining entheseal structures with great resolution because most of these are superficial structures. Entheseal abnormalities can be documented by ultrasonography in clinically asymptomatic patients with Diabetes. These findings could be related to a subclinical entheseal inflammation.
