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).

Thelitis in Buffalo Heifer

THELITIS                  Thelitis is a disease affecting primarily the h igh-yielding primiparous graded Murrah milch buffaloes and causing serious economic losses to the farmers.                The disease is characterized by acute inflammation of one or more teats with subsequent thickening, narrowing or closure of the teat canal leading to incomplete milk drainage.                The quality of milk appears to be normal unlike in clinical mastitis.               Thelitis may lead to ulceration, focal necrosis, and partial or complete sloughing off the affected teat.                Healing may be delayed due to the trauma of milking and secondary bacterial infections.

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
