查询词典 retroversion

The use of the transverse ligament has been shown to be a dependable landmark for the anteversion of the cup, as shown by Archbold and Beverland et al.13 By placing the cup parallel to the transverse ligament this prevents excessive anteversion or retroversion of the cup, thus placing the cup in the centre of the patient's functional range, enhancing the joint's stability.

超过此界限值，脱位风险率将从1.5%增加6.1%不等。Archbold与Beverland等指出，髋臼横韧带是臼杯前倾角可靠的参考标志13。

Results: Transverse diameters of left and right humeral heads were (40.67±1.90)mm and (40.49±1.36)mm, vertical diameter (44.54±1.31)mm and (43.45±1.48)mm, retroversion angle (26.59±1.36)° and (26.85±1.61)°, max interval of humeral head-tuberosity (6.63±1.13)mm and (6.80±1.02)mm, humeral head-shaft angle (l34.320±3.49)° and (135.58±1.50)° respectively.

结果：肱骨头横径：左侧(40.67±1.90)mm，右侧(40.49±1.36)mm；肱骨头纵径：左侧(44.54±1.31)mm，右侧(43.45±1.48)mm；肱骨头后倾角：左侧(26.59±1.36)°，右侧(26.85±1.61)°；头结节距（肱骨头最高点至大结节最高点的垂直距离）：左侧(6.63±1.13)mm，右侧(6.80±1.02)mm；颈干角：左侧(134.320±3.49)°，右侧(135.58±1.50)°。

Methods:Fifty paired embalmed cadaveric humeri (twenty-five pairs:fourteen from male donors and eleven from female donors) were scanned in medial-lateral and anterior-posterior position according to the humeral retroversion by CT. Images of the humeri in the transverse planes at the lowest border of neck,20mm and 40mm distal of LBN(LBN-20、LBN-40), isthmus, head-neck anterior-posteriorwere obtained. Sixty-one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head-shaft angle, head to tuberosity height, head thickness, curvature radius, articular surface arc, neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including LBN, LBN-20,LBN-40 and isthmus.
