1 Macalister and some other Ent>lUh anatomists agree with Toldt in naming this ligament tlir ////,v-,'A.t ( ';/A sa< m-ilia< ligament. That 

 name is. however, misapplied, s nee the fibres of the ligament do not connect two closely adjacent parallel articu'ar surfaces. True inter- 

 osseous fine fibres are occasionally found connecting corresponding parts of the auricular surfaces of the sacrum :*n<l the- ilium. TK. 



FIG. 453. POSTERIOR LIGAMENTS OF THE PELVIC GIRDLE : LIGAMENTUM SACROTUBEROSUM, 

 POSTERIOR OR GREAT SACROSCIATIC LIGAMENT, AND ITS RELATION TO THE POSTERIOR 

 LAYER OF THE LUMBAR APONEUROSIS. FORAMINA ISCHIADICA, SACROSCIATIC FORAMINA. 

 LIGAMENTUM SACRO-ILIACUM POSTERIUS LONGUM, LONG OR OBLIQUE (POSTERIOR) SACRO- 

 ILIAC LIGAMENT; LIGAMENTA SACRO-ILIAC INTEROSSEA, POSTERIOR SACRO-ILIAC LIGAMENT 

 (see note above); LIGAMENTUM ILIOLUMBALE, ILIOLUMBAR LIGAMENT. (Tin; PELVIS WITH 

 THE FOURTH AND FIFTH LUMBAR VERTEBRA ; SEEN FROM BEHIND.) 



On the right side, the posterior layer of the lumbar aponeurosis has been divided close to its 

 continuation into the posterior or great sacrosciatic ligament, and turned outwards ; cm the left 

 side, this superficial portion of the posterior or great sacrosciatic li -ament has been cut across, 

 and the divided ends have been turned upwards and downwards. The lowermost fibres of 

 the middle layer of the lumbar aponeurosis have on the right side been left intact, but on the 

 left side entirely removed.
