    COMPARISON BETWEEN THE SCOLIOTIC iND OBLIQUELY CONTIUCTED (NAEGELE) PELVES. It is impossible to compare a scoliotic pelvis witli a pelvis of Naegele without seeing many points of resemblance which are the more instructive from the difference of the original conditions of distortion. This will be seen most easily from the following table:— Scoliotic. Naegele. Cause.—Scoliosis of lumbar vertebrae. Cause. — Ankylosis of Effects.—(1) Increase of pressure on the sacro-ihac joint of the overweighted (same) side. (2) Dwarfing of os innominatum of same side. (3) Dwarfing of sacral ala of same side. (4) Traction at post. sup. spine of opposite side. (5) Expansion of opposite side. (6) Horizontal rotation of sacrum at sacro-iliac joint towards affected side. (7) Approximation of sacrum of same side to acetabulum (narrowing of sacro-cotyloid dia- meter). (8) Increasing weight thrown on affected side of pelvis. (9) Rotation of ilium of aflfected side round acetabular axis. (10) Rotation round antero-posterior axis ; ever- sion of tuber ischii; enlargement of transverse diameter of outlet. (11) Increase of curve of posterior part of linea innominata, diminution of curve in anterior part on affected side. (12) Symphysis driven to opposite side. (13) Narrowing of conjugate (sometimes). Cause. sacro-iliac joint Effects.—(1) Do. (2) (3) (4) (5) (6) Do. Do. Do. Do. Do. (7) Do. (8) Do. (9) Do. (10) Inversion of tuber ischii, contraction of trans, diameter of outlet. (11) Linea innominata almost straight. (12) Do. (13) No contraction of conjugate, sometimes enlargement.
