Obturator

An appendix sitting behind the obturator muscle causes a pain sensation in the pelvis, sometimes only detected with a rectal exam. ❋ Unknown (2003)

When paralysis of the obturator nerve occurs as a post-partum complication, and other conditions are favorable, the subject should be raised to its feet without unnecessary delay. ❋ John Victor Lacroix (N/A)

I also never saw a case of localised obturator paralysis. ❋ George Henry Makins (N/A)

By removing the os innominatum, A D, Plate 48, together with the internal obturator, and levator ani muscles, which arise from its inner side, we obtain a lateral view, Plate 49, of the pelvic viscera, and of the vessels &c. connected with them. ❋ Joseph Maclise (N/A)

The nerves (one or both) may become bruised at the brim of the obturator foramen by being caught between the pelvis and the body of the fetus in some cases of protracted labor. ❋ John Victor Lacroix (N/A)

G. G. Positions of the obturator artery when given off from the epigastric. ❋ Joseph Maclise (N/A)

-- The obturator nerve, situated at first under the peritoneum, accompanies the obturator artery through the obturator foramen and gaining the muscles on the internal face of the thigh, terminates in the obturator externus, adductors, pectineus and gracilis, also giving twigs to the obturator internus (Strangeways). ❋ John Victor Lacroix (N/A)

On the tenth day subsequent to the injury, the hyperæsthesia in the area of lumbar supply was replaced by normal sensation, motor power began to be slowly regained in the muscles supplied by the anterior crural and obturator nerves, and the patellar reflex returned. ❋ George Henry Makins (N/A)

Monro (Obs. on Crural Hernia) states this condition of the obturator artery to be as 1 in 20-30. ❋ Joseph Maclise (N/A)

The artery, in company with the nerve and vein, re-enters the pelvis by the small sciatic foramen, and gets under cover of a dense fibrous membrane (obturator fascia), between which and the obturator muscle, it courses obliquely downwards and forwards to the forepart of the perinaeum. ❋ Joseph Maclise (N/A)

In some cases of dystocia the obturator nerve, (or nerves, if the involvement is bilateral), becomes injured by being caught between the maternal pelvis and some dense part of the fetus. ❋ John Victor Lacroix (N/A)

When the obturator artery is derived from the epigastric, if the former pass internal to the neck behind, 8, Gimbernat's ligament, it can scarcely escape being wounded when this structure is being severed by the operator's knife. ❋ Joseph Maclise (N/A)

Moller, [37] quoting Nocard, describes a case where fracture occurred through the region of the foramen ovale and paralysis of the obturator nerve followed. ❋ John Victor Lacroix (N/A)

In one instance damage particularly affecting the lumbo-sacral cord occurred, but this was complicated by signs of irritation of the anterior crural and obturator nerves, as the result of retro-peritoneal hæmorrhage and injury to the psoas muscle. ❋ George Henry Makins (N/A)

"What determines the position of the obturator artery with respect to the femoral ring?" ❋ Joseph Maclise (N/A)

Paralysis of the obturator nerve or nerves is met with rather frequently, notwithstanding, in mares, following dystocia. ❋ John Victor Lacroix (N/A)

Branches supply the following muscles -- obturator, semimembranosus (adductor magnus), biceps femoris (triceps abductor femoris), semitendinosus (biceps rotator tibialis), lateral extensor ❋ John Victor Lacroix (N/A)

And if the obturator artery, [Footnote] by rare occurrence, happen to loop round the inner side of the neck of the sac, supposing this to be the seat of stricture, what amount of anatomical knowledge, at the call of the most dexterous operator, can render the vessel safe from danger? ❋ Joseph Maclise (N/A)
