Abstract
Six adult (Three males and three females) dogs were used to evaluate the effectiveness of pin-in-fiberglass cast, Kirschner-Ehmer external fixative and fiberglass cast in the management of surgically created radius and ulna fractures in dogs. These dogs were assigned to three groups (A, B, and C) with each group made up of two dogs. The dogs were all treated under general anaesthesia for midshaft radius and ulna fractures as follows: Group A,pin-in-fiberglass casts; Group B, Kirschner-Ehmer external fixatives; and Group C, Fiberglass casts. The dogs were administered Diclofenac Sodium (4 mg/kg) pre- and post-operative. Minimal increase in vital parameters value post-operative were insignificant (P>0.05) when compared with pre-operative values for all the groups. Radiographic evaluation revealed minimal soft tissue swelling and periosteal tissue reaction in all the groups. Adequate callus formation was observed at the 6th week forgroup A and B, and 10th weekfor C post-operative respectively. Group B attained the fastest fracture healing time (7 weeks) followed by Group A (8weeks) and Group C (12 weeks). Dogs of group A and B bore weight on the operated limb and could walk on day 1 post-operative, while these were observed on day 10 for dogs of group C. Functional and cosmetic appearances were graded as excellent for group A and B, and fair for group C.The overall duration of repair was less for the pin-in-fiberglass cast technique (5.5 hours) than the Kirschner-Ehmer external fixation (22 hours) and the fiberglass cast techniques (8.5 hours). The operative and post-operative management cost analysis of pin-in-fiberglass casting, Kirschner-Ehmer external fixation and fiberglass casting were N11,550, N54,350, N7,750 respectively.However, the potential economic implication to a dog breeder for pin-in-fiberglass casting, Kirschner-
Ehmer external fixation and fiberglass casting techniques were, N191,550N214,350, and N307,750 respectively. Pin-in-fiberglass casting was most economical. Complications associated with wound healing and haematological indices were within acceptable normal limits. Thus, it was concluded that pin-in-fiberglass cast is easily applicable and produce desired result in the managementof radius and ulna fractures in dogs.
