Realistic computer simulation of neurosurgical procedures requires incorporation of the mechanical properties of brain tissue in the mathematical model. Possible applications of computer simulation of neurosurgery include non-rigid registration, virtual reality training and operation planning systems and robotic devices to perform minimally invasive brain(More)
Twenty-nine feet in 28 patients who underwent subtalar distraction bone block fusion for the treatment of subtalar deformities associated with symptomatic arthrosis were evaluated. All patients were assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale score. Eighteen men and 10 women with a mean age of 44 years were(More)
The intermediate outcome of patients who underwent a modified Lapidus procedure for the treatment of hallux valgus secondary to a hypermobile first ray was evaluated with an outcome tool to determine if their pain and functional status were improved. We evaluated 31 feet in 26 patients who underwent a modified Lapidus procedure. All working patients (100%)(More)
Several studies of retrieved glenoid components from total shoulder arthroplasty show an erosion of the rim, surface irregularities, component fracture and wear resulting from polyethylene deformation in vivo. Particles resulting from polyethylene wear might be one of the reasons for the very high rate of glenoid component loosening found clinically.(More)
SUMMARY Bayesian Networks (BNs) are versatile probabilistic models applicable to many different biological phenomena. In biological applications the structure of the network is usually unknown and needs to be inferred from experimental data. BNFinder is a fast software implementation of an exact algorithm for finding the optimal structure of the network(More)
We reviewed the records of 12 patients ages 9 to 16 years with knee osteochondritis dissecans. All patients had clinical histories and examinations, four radiographic views of the knee, and technetium-99m diphosphonate quantitative bone scans. Scan results (symmetric, increased, or decreased activity), clinical course, healing time, and final outcome were(More)
In eukaryotic cells, the DNA material is densely packed inside the nucleus in the form of a DNA-protein complex structure called chromatin. Since the actual conformation of the chromatin fiber defines the possible regulatory interactions between genes and their regulatory elements, it is very important to understand the mechanisms governing folding of(More)
The intermediate outcome of patients who underwent a triple arthrodesis for the treatment of adult foot disorders was evaluated with an outcome tool to determine if their pain and functional status were improved. We evaluated 63 feet in 57 patients who underwent a triple arthrodesis using rigid internal fixation for the treatment of hindfoot deformities(More)
