Proteus syndrome is an extremely rare genetic disorder characterized by an asymmetrical overgrowth of skin, bones, muscles, fatty tissues, and blood and lymphatic vessels. We present a case of a six-year-old boy with proteus syndrome who underwent bone scintigraphy for suspected osteomyelitis. Bone scintigraphy ruled out osteomyelitis and suggested cellulitis. In addition, it demonstrated strik...

Three adult patients with cystic fibrosis presented with arthralgia, and investigation for the usual causes of arthritis proved negative. Radiographs of long bones revealed periostitis and new bone fromation characteristic of hypertrophic osteoarthropathy. Symptomatic improvement occurred after analgesic and anti-inflammatory therapy. In patients with cystic fibrosis and bone or joint pain, the...

INTRODUCTION Osteogenesis imperfecta (OI) is a genetic disorder that affects the production of type I collagen. A major characteristic of OI is bone fragility, caused in part by bone mass deficiency [1]. Impaired collagen network and abnormal mineralization have also been observed in OI [2,3], suggesting that bone material properties are also compromised. Little data, however, is yet available ...

background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

osteoid osteoma is a unique benign primary bone tumor that may present in the metaphyseal diaphyseal areas of the short tubular bones and has also been reported in the carpal bones. it occurs in the first two decades of life. the classic history is bone pain, often relieved by aspirin. the clinical appearance is local swelling and tenderness. the typical radiographic appearance is very characte...
