Objective: To compare the clinical efficacy of CT-guided radiofrequency ablation and open surgery in the treatment of osteoid osteoma of the spine. Methods: From June 2012 to June 2016, 45 patients with osteoid osteoma of the spine were treated with CT-guided radiofrequency ablation in 23 cases (Group A) and open surgical resection in 22 cases (Group B). The out-of-bed activity time, visual ana...

osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

BACKGROUND This study evaluates the clinical, radiological, histological, and histomorphometric aspects of a fully synthetic biphasic calcium phosphate (BCP) (60% hydroxyapatite and 40% ß-tricalcium phosphate), used in a human maxillary sinus floor elevation (MSFE) procedure with 9- and 12-month healing time. METHODS A unilateral MSFE procedure, using 100% BCP, was performed in two series of ...

BACKGROUND A lot of advantages can result in a high wettability as well as a nanostructure at a titanium surface on bone implants. Thus, the aim of this study was to evaluate the osseointegrative potential of a titan plasma-sprayed (TPS) surface refinement by acid-etching with chromosulfuric acid. This results in a hyperhydrophilic surface with a nanostructure and an extreme high wetting rate. ...

Osteoid osteoma is a rare bone tumor initially described by Jaffe in 1935. It is characterized as a bone-producing tumor that is most frequently observed in the lower extremities of children or young adults (11-22 years). Osteoid osteoma is differentiated from osteoblastoma according to size. Osteoid osteoma is smaller than 1.5 centimeters in diameter. In approximately 10% to 25% of the cases, ...

BACKGROUND Various clinical reports suggest etanercept (ETN) has some efficacy in bone formation in rheumatoid arthritis (RA). To examine this effect, we investigated the gene expression of cytokines relevant to osteoblast/osteoclast differentiation, and evaluated histomorphometric findings in mature rats with collagen-induced arthritis (CIA). METHODS Total RNA was extracted from knee joints ...

Osteoid osteoma (OO) is a small and painful benign osteoblastic tumour located preferentially in the shaft of long bones near the metaphyseal junctions, with a predilection for the lower limbs. Juxta- and intra-articular OOs are rare and even though hip, elbow, and talus are the most commonly reported locations, they may be found in any joint accounting for approximately 13% of all osteoid oste...
