An oval swelling forms in the upper part of the thigh, is soft and prominent when the muscle is relaxed, less prominent when it is passively extended, and disappears when the muscle is thrown into contraction. It is liable to be mistaken, according to its situation, for a tumour, a cyst, a pouched vein, or a femoral or obturator hernia.
Paralysis of the obturator nerve or nerves is met with rather frequently, notwithstanding, in mares, following dystocia. Symptomatology. In a unilateral affection there may be little evidence of the trouble while the subject is standing; or there is to be seen some abduction; or the affected member may present abduction of the stifle and stand "toe outward."
Sercombe mentions a case in which destruction of the entire palate was successfully relieved by mechanical means. In some instances among the lower classes these obturators are simple pieces of wood, so fashioned as to fit into the palatine cleft, and not infrequently the obturator has been swallowed, causing obstruction of the air-passages or occluding the esophagus. Abnormalism of the Uvula.
No infection or other bad results will follow the execution of a good technic and the treatment may be repeated every three or four weeks until either marked regeneration of tissue is evident or the case is obviously proved hopeless. Paralysis of the Obturator Nerve. Anatomy. Etiology and Occurrence.
Pistons of aluminium alloy, with three cast-iron rings, are fitted, the top ring being of the obturator type. The large end of one of the nine connecting rods embraces the crank pin and the pressure is taken on two ball-bearings housed in the end of the rod.
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. If the mare is unable to assist in regaining her feet, a sling is required. Usually little else is necessary and after a few days in the sling the subject can get about unassisted.
The Indians advised me approximately of the depth to which the shaft had penetrated and the direction it took, and judging from the situation of the cicatrix and all the circumstances it was apparent that the arrow-head had passed through the glutei muscles and the obturator foremen and entered the cavity of the bladder, where it remained and formed the nucleus of a stone.
Moller, quoting Nocard, describes a case where fracture occurred through the region of the foramen ovale and paralysis of the obturator nerve followed. Fractures which include the acetabular bones cause great pain. This is manifested by marked lameness, both during weight bearing and when the member is swung. Such cases terminate unfavorably complete recovery is impossible.
In the case of Roux in 1891 the hernia existed on both sides. The uterus has been found twice only in crural hernia and three times in umbilical hernia. There is one case recorded, according to Debierre, in which the uterus was one of the constituents of an obturator hernia. Sometimes its appendages are found with it.
Such are possibly nevoid in formation. The ordinary anomalies of the palate are the fissures, unilateral, bilateral, median, etc.: they are generally associated with hare-lip. The median fissure commencing between the middle incisors is quite rare. Many curious forms of obturator or artificial palate are employed to remedy congenital defects.
