| தொகà¯à®ªà¯à®ªà¯: | Introduction:
Critical size defects (CSD) in the long bones of New Zealand White rabbit (Oryctolagus cuniculus) have been used for years as an experimental model for
investigation of the effectiveness of a new bone substitute materials. There are varieties of protocols available in the literature. This technical note attempts to present an
alternative surgical technique of a CSD in the New Zealand white rabbit tibia.
Methods:
Thirty-nine New Zealand White rabbits were used in this study. A CSD of approximately 4.5 mm (width) X 9.0 mm (length) was surgically drilled at the proximal tibial metaphysis, approximately 1 cm from the knee joint. The surrounding of soft tissue was repositioned and sutured layer by layer with bio absorbable surgical suture. Povidone soaked gauze and bandage were used as a dressing. There is no control group used in this study.
Results:
This alternative method created good CSD with less bleeding from the muscle observed.No mortality on other surgical complications were observed within 6 weeks, 12 weeks and
24 weeks following surgery. Conclusions: A simple and safe method for performing critical size defect was demonstrated and recommended as an approach for surgery on New
Zealand White rabbits. |
