Background: Metabolic bone diseases are a common complication of chronic kidney diseases (CKD) and is part of a broad spectrum of disorders of mineral metabolism associated with secondary hyperparathyroidism. Musculoskeletal Ultrasound (MSUS) is used to assess characteristics of joint, superficial tendons and ligaments that traverse a joint. It can demonstrate the presence of effusion, bursae or cysts and it can also detect loose bodies in joints. Aim of the work: The aim of this study was to assess the shoulder joint involvement in patients undergoing regular renal hemodialysis using musculoskeletal ultrasound imaging. Materials and methods: this study was carried out on 40 patients together with a group of 20 age and sex matched apparently healthy subjects as a control group. Patients were devided into two subgroups: Ia with shoulder pain and Ib without shoulder pain. All patients underwent history taking, clinical examination, general and local shoulder joints, plain radiography, MSUS performed on the shoulders and laboratory evaluation including PTH serum amyloid for the involved subjects were done. Results: Serum amyloid and PTH levels were markedly raised in all patients( p< 0.001), MSUS abnormalities most commonly affected the bicips tendon 32 /40 ( 80 %), followed by supraspinatus tendon 18/40 ( 45 %) then subscapularis tendon 8 /40 (20 %) ,while the infraspinatus tendon 2/40 ( 5 %) was the least affected tendon. Tendon degeneration occurred in 32/160(20 %) of the examined tendons, tendon tear occurred in 12/160 (7.5 %), tenosynovitis around bicips tendon was detected in 12/40(30 %) and calcifications were detected in 4/160(2.5 %) tendons. There were highly statistically significant differences between CKD patients and controls regarding mean tendon thickness, with the biceps and supraspinatus tendons thicker in the study groups (p |
