Obturator Nerve Paralysis along with Stifle dislocation

Obturator Nerve Paralysis

Excessive pulling to deliver a calf, pulling a calf straight out from the cow rather than down and backwards or having the calf in the birth canal too long (several hours), predisposes the nerve to mechanical injury.

This is common when assisted delivery is done without involving an experienced veterinarian and where there is feto-pelvic disproportion.

Signs showing the abduction of right and left hind limb and hind limb extend forward.

Stifle Dislocation

A downer cow in lateral recumbency. On clinical examination hind limb is abducted and on extension of hind limb it forms an angle 90 degree (Perpendicular to body ) suggestive of dislocation ie. Stifle dislocation (Luxation of stifle joint).

Gastrocnemius Muscle rupture in Various animals

Gastrocnemius Muscle rupture in Various animals 1. Rupture of the gastrocnemius muscle is an injury with or without the Achilles tendon. It was observed in the cow, camel, horse, and humans. 2. Either the rupture may occur immediately after an injury, or the muscle or tendon may be weakened enough so that a mild strain may completely rupture it later. 3. In cattle, the most common sites of muscle rupture are at the Musculo-tendinous junction, and at the origin or insertion of the muscle. 4. The rupture of the gastrocnemius muscle may occur partially or completely . In the partial rupture, the signs are less pronounced, and the prognosis is better than that in the complete rupture. 5.In complete rupture animal will rest on its hock (Metatarsal will be Parallel to ground) whereas in mild cases dropped hock is the p...

Tunica albuginea was intact in both open and closed prescrotal castration. Note: The risk of ligature slippage and loosening may be slightly greater in closed techniques compared to open techniques .

0mphalocele - A Day old Puppy

Omphalocele Umblical hernia are usually congenital caused by Flawed Embryogenesis - Inherited. Umbilical vessels, Vitelline duct and stalk of the allantois pass through the umblical ring in the fetus but this aperture close at birth leaving an umblical cicatrix. If the aperture fails to contract or too large or improperly formed leads to Hernias. The hernia was lined by peritoneal sac hence it is called True Hernia. Male dog with Umblical Hernia are Cryptorchid. The abdominal content initially are covered by amniotic but this covering is easily ruptured. Reference : Theresa Welch Fossum - Small Animal Surgery
