Egg binding and hind limb paralysis in an African penguin--a case report.

This case report assesses the role acupuncture played in the rehabilitation therapy of an African penguin with bilateral hind limb paresis and paralysis following egg binding and a caesarean section. Egg binding is the failure of the oviduct to pass the egg down into the cloaca. In avian species the sciatic nerve runs through the middle of the kidney. Swelling of the kidney tissue due to the pressure exerted by the retained egg will cause pressure on the sciatic nerve which may lead to hind limb paresis/paralysis. Acupuncture was used to relieve any muscle, joint or nerve pain and to attempt to stimulate recovery of the sciatic nerve. Acupuncture was incorporated into a fairly intensive physical rehabilitation programme to help the penguin to walk again so that it could be re-introduced back into the sanctuary's captive colony.
