Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis.(More)
Bipartite patella is usually an asymptomatic, incidental finding. However, in adolescents, it may be a cause of anterior knee pain following trauma or a result of overuse or strenuous sports activity. Most patients improve with nonsurgical treatment. Surgery is considered when nonsurgical treatment fails. Excision of the fragment is the most popular(More)
INTRODUCTION The purpose of this study was to analyse the applicability and advantages of the intraoperative use of a mobile isocentric C-arm with three-dimensional imaging (Siremobil ISO-C-3D) in fixation of intraarticular fractures. METHODS After the fixation was judged to be satisfactory relying on the images provided by routine fluoroscopy,(More)
Mastering rapidly evolving orthopaedic surgical techniques requires a lengthy period of training. Current work-hour restrictions and cost pressures force trainees to face the challenge of acquiring more complex surgical skills in a shorter amount of time. As a result, alternative methods to improve the surgical skills of orthopaedic trainees outside the(More)
BACKGROUND The purpose of this study was to assess the safety and efficacy of computed tomography (CT) guided percutaneous radiofrequency (RF) ablation of osteoid osteoma by using the water-cooled probe. METHODS During the period from July 2002 to February 2006, fifty-one patients with osteoid osteomas localized in femur (29), tibia (10), calcaneus (2),(More)
The objective of this study was to evaluate the effects of local endothelial progenitor cell (EPC) therapy on bone regeneration in a rat model. A segmental bone defect (5 mm) was created in the femur and fixed with a mini-plate. There were two groups: EPC-treated (N = 28) and control (N = 28). Seven animals were sacrificed from each group at 1, 2, 3, and 10(More)
Introduction Computer assisted technology brings important digi-tised information into the operating room, enabling the accomplishment of two main goals: minimal invasive surgery and maximal accuracy. Moreover , both surgeon and patient enjoy a significant Summary Introduction: CT (ISO-C-3D) image based navigation has recently been introduced to improve the(More)
Orthopaedic research has advanced tremendously in parallel with accelerated progress in medical science. Possession of a fundamental understanding of basic and clinical science has become more essential than previously for orthopaedic surgeons to be able to translate advances in research into clinical practice. The number of medical graduates with prior(More)
PURPOSE The objective of this study was to evaluate the effects of synovium on the proliferation of the cartilage tissue and chondrocytes using a rabbit knee model as an in vivo synovial culture medium. METHODS Twelve New Zealand rabbits were used as the animal model in this investigation. Standard size chondral and osteochondral cartilage grafts were(More)
