OBJECTIVES To assess the accuracy of coronal and sagittal CT sections to detect cavities simulating root resorption. MATERIAL AND METHODS 60 mandibular incisors were embedded in plaster bases, and cavities with 0.6, 1.2 or 1.8 mm in diameter and 0.3, 0.6 or 0.9 mm in depth (small, medium and large cavities) were drilled on the buccal surfaces with high-speed round burs with diameters of 0.6, ...

Tension in an anterior cruciate ligament graft is greater with the knee in flexion when the angle of the tibial tunnel in the coronal plane is vertical or more perpendicular to the medial joint line of the tibia; however, the relationship of the angle of the tibial tunnel to knee function has not been studied. Greater graft tension may limit knee flexion or stretch the graft and increase anteri...

BACKGROUND Coronal imbalance of the pelvis is recognized to lead to the development of degenerative lumbar scoliosis. We hypothesized that an abrupt change of pelvic obliquity may show a reproducible trend of coronal compensation in the lumbosacral spine. The aim of the study was to classify the change of coronal alignment of spine after THA. METHODS This is a retrospective study based on the...

OBJECTIVES To examine the feasibility of imaging the fetal cochlea in the early second trimester. METHODS This study included 42 healthy fetuses of low-risk pregnancies between 14 and 16 weeks. The coronal head sections via sagittal and lateral acoustic windows were used for cochlear visualization. The coronal plane was directed across the thalamus, oriented to the petrous part of the tempora...

BACKGROUND CONTEXT The XLP plate is an anterolateral instrumentation system developed as a part of the eXtreme Lateral Interbody Fusion (XLIF) system for lateral transpsoas interbody fusion, an alternative to anterior interbody fusion. PURPOSE To report two cases of atraumatic coronal plane vertebral body fractures in the early postoperative period after interbody fusion using XLIF cages, lat...

Solar prominences are cool 10(4) kelvin plasma clouds supported in the surrounding 10(6) kelvin coronal plasma by as-yet-undetermined mechanisms. Observations from Hinode show fine-scale threadlike structures oscillating in the plane of the sky with periods of several minutes. We suggest that these represent Alfvén waves propagating on coronal magnetic field lines and that these may play a role...

BACKGROUND The purpose of this study was to provide practical data for the imaging diagnosis of the optic pathways. METHODS Sectional anatomy of the optic pathways on the coronal plane was investigated on 15 sets of serial coronal sections of the head of Chinese adult cadavers and 6 sets of serial coronal magnetic resonance imaging of normal adults. RESULTS On the coronal plane, we recogniz...

BACKGROUND The injury of the triangular fibrocartilage complex (TFCC) is a common cause of ulnar-sided wrist pain. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) could demonstrate the detailed complex anatomy of TFCC in Chinese. METHODS Fourteen Chinese cadaveric wrists (from four men and three women; age range at death from 30 to 60 years;...

Unicondylar fractures of the lower end of the femur are uncommon injuries that usually occur in the saggital plane 2. Coronal (tangential) plane fractures, first described by Hoffa in 1904, are unusual.(1,2, 3,4) We report our experience with three cases and the mechanism of injury is discussed. Open reduction and internal fixation is mandatory for good long-term results.
