Application of Allograft in Orthopaedic Surgery at Hatyai Hospital - Live Demonstration of two cases
Surgical procedures were carried out at the Hatyai Hospital, Hatyai, Thailand. Request for the grafts were placed at the Bangkok Biomaterial Center by the Consultant Orthopaedic Surgeon responsible for the cases. After reviewing the X-rays and following the regular protocol of our center, the grafts were dispatched to the hospital one day in advance. The scheduled date for the surgery was 30th of March 1999. The team from our center left for Nakhorn Ratchsima in two batches.

The details of the surgery are mentioned below. Both the cases involved the application of allograft in the femur and pelvic. The first case as indicated below was Osteosarcoma in the shaft of femur of a 13 years old boy. So it was attempted to use the shaft of a whole Humerus. To compensate the bone loss. The 2nd case being a revision total hip arthoplasty with acetabular migration, a head of femur was used to fill in the acetabular defect. Details of the process are indicated in the particular cases..
