Morphometric analysis of the angle of the femoral trochlea

The possible association between disorders of the femoropatellar joint and geometrical anatomical variations in the patellar facet and femoral sulcus motivated us to conduct a morphometric study on the angle of the femoral sulcus and to correlate this with possible variation factors, such as: length, width at the midpoint of the femur, femur inclination angle, distance between condyles and depth of the patellar facet. The material consisted of 56 dry femurs of both sexes and various ages: 24 from the right side and 32 from the left side. The patellar facets were photographed at three positions: a) start level; b) middle level; and c) end level. The angle formed in each of these positions was measured using graphical tools in CorelDraw X4. To analyze the results, the statistical tests used were chi-square and Student’s t-test for correlations. The results obtained were: a) angle of the patellar facet: mean for start level of the patellar facet = 129°01; mean for middle level = 131°35 and mean for end level = 132°14; b) mean distance between condyles = 50.29  mm; c) mean depth of the patellar facet = 9.55 mm; d) mean for Ficat and Bizou’s condylar depth index = 5.45. We concluded that the angle of the femoral sulcus increased from the start of the patellar facet to its end, and that its variability was weakly influenced by the length, width, femur inclination angle and side, according to the t-test (significance of 5%) for the correlation coefficients found.

Sella turcica morphometry usingcomputed tomography

Along the development of imaging diagnosistechnology, it has become increasingly importantto perform morphological research usingimages. Our aim here was to study the sellaturcica using tomographic imaging in differentplanes of section that would reveal itsshape and morphometry, correlating such datawith the cranium-cephalic index, age and sexof the skulls analyzed. For this study, one hundredskulls from the Department of Anatomyat UNIFESP were used. The material, afterbeing measured and classified, was subjectedto tomography in three planes, coronal, axialand sagittal, and immediately after this, thefollowing measurements were calculated withthe images obtained: height on sagittal sections,length on axial sections and area of thesella on sagittal sections. The results for thesella turcica radiological measurements were asfollows: length from 6 to 15.1 mm, with amean of 10.31 mm; height from 2.9 mm to11.1 mm, with a mean of 6.33 mm, and areafrom 8 mm? to 79 mm? with a mean of 41.21mm?. The sella turcica is a constant anatomicstructure, but with a variable shape (AU)
