Clinical and imaging findings of patients diagnosed with pyogenic sacroiliitis were retrospectively analyzed. ⋯ Both magnetic resonance imaging and technetium bone scanning are sensitive for localizing occult sites of bone inflammation. Magnetic resonance imaging may provide more useful information than bone scanning by screening for abnormalities in the sacroiliac joint region. With prompt appropriate antibiotic therapy, clinical improvement of patients can be expected.

Comparative Study
Prospective comparison of gait and trunk range of motion in adolescents with idiopathic thoracic scoliosis undergoing anterior or posterior spinal fusion.
Prospective evaluation of gait and spinal range of motion (ROM) in adolescent idiopathic scoliosis (AIS) patients undergoing either an anterior or a posterior spinal fusion. ⋯ The surgical and ROM results seem to favor the anterior approach over the posterior approach for the classification of patients in this investigation. However, it should be noted that both groups had decreased postoperative ROM.

Electromagnetic field-based image-guided spine surgery part two: results of a cadaveric study evaluating thoracic pedicle screw placement.
Human cadaveric. ⋯ Our study has shown that EMF image-guided thoracic pedicle screw placement results in a similar incidence of safely placed screws as does conventional fluoroscopy. When set-up time and image-capture time were factored in for image guidance, the average time to insert a pedicle screw was equal for both techniques. The use of EMF image guidance significantly reduced fluoroscopic time and thus radiation exposure per screw compared with conventional fluoroscopic techniques.

Comparative Study
Significance of chin-brow vertical angle in correction of kyphotic deformity of ankylosing spondylitis patients.
A prospective study. ⋯ Chin-brow vertical angle was an objective index for evaluating horizontal gaze. Based on the results of this study, measurement of chin-brow vertical angle is recommended for planning correction of kyphosis and accurate evaluation of treatment outcome.
