| osteitis condensans ilii | Symmetric benign osteosclerosis of the portion of the iliac bones adjacent to the sacroiliac joints. (05 Mar 2000) |

| osteitis deformans | This is a disease of bone that initially results in the excessive resorption of bone (by osteoclasts) followed by the replacement of normal bone marrow with vascular and fibrous tissue. Many patients are asymptomatic and diagnosed by routine X-rays. (27 Sep 1997) |
| osteitis fibrosa | <radiology> Secondary to hypocalcaemia and hyperphosphataemia followed by increased parathormone production, subperiosteal bone resorption, radial aspect of phalanges, distal clavicle, medial tibia plateau, medial humerus neck, distal ulna, phalangeal tufts, lamina dura of teeth, subchondral and subligamentous bone resorption, widening of symphysis pubis, SI joints, resorption of ischial tuberosity, spotty deossification of the skull (wooly, salt and pepper), metaphyseal fractures, slipped epiphyses, brown tumour and chondocalcinosis, more common in primary hyperparathyroidism see: renal osteodystrophy (12 Dec 1998) |
| osteitis fibrosa circumscripta | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
| osteitis fibrosa cystica | Rarefying osteitis with fibrous degeneration and formation of cysts, and with the presence of fibrous nodules on the affected bones. It is due to marked osteoclastic activity secondary to hyperfunction of the parathyroid glands. (12 Dec 1998) |
| osteitis fibrosa disseminata | The occurrence of lesions of fibrous dysplasia in multiple bones, commonly on one side of the body; may occur with areas of pigmentation and endocrine dysfunction (McCune-Albright syndrome). Synonym: multifocal osteitis fibrosa, osteitis fibrosa disseminata. (05 Mar 2000) |
| osteitis pubis | Osteosclerosis of the pubic bone next to the symphysis, caused by trauma to that region, from pregnancy or instrumentation. (05 Mar 2000) |
| focal condensing osteitis | A reaction of bone to a mild bacterial infection, often the result of a carious tooth, in persons with a high degree of tissue resistance; results in a localised radio-opacity. Synonym: focal condensing osteitis. (05 Mar 2000) |
| localised osteitis fibrosa | Fibrous dysplasia of a single bone. Synonym: localised osteitis fibrosa, osteitis fibrosa circumscripta. (05 Mar 2000) |
