Musculoskeletal manifestations of chronic renal insufficiency.
Abnormalities involving the musculoskeletal system are numerous and frequent in patients with chronic renal insufficiency (CRI). The most common radiologic manifestations of CRI are those referred to collectively as renal osteodystrophy: the findings seen in secondary hyperparathyroidism (bone resorption, periosteal reaction, and brown tumors), osteoporosis, osteosclerosis, osteomalacia, and soft-tissue and vascular calcification. Bone resorption, the most frequent alteration of CRI, occurs in several locations (subperiosteal, subchondral, trabecular, endosteal, and subligamentous), whereas brown tumors and periosteal reaction are much less common. Osteosclerosis primarily affects the axial skeleton and may be the only sign of CRI. Osteoporosis and osteomalacia cause osteopenia and are not infrequent changes of CRI. The prevalence of calcifications increases with the duration of hemodialysis. The other major group of musculoskeletal abnormalities attributable to CRI includes aluminum deposition, amyloid deposition and destructive spondyloarthropathy, tendon rupture, crystal deposition, infection, and avascular necrosis. These changes are less common than those of renal osteodystrophy and are more frequently seen in patients who have undergone long-term hemodialysis or renal transplantation. Recognition of musculoskeletal manifestations is important in the clinical management of patients with CRI.
