Abstract:
The effect of surgical perforation of the disc on intra-articular morphology was examined using sheep. Eight sheep had bilateral perforations and 2 animals were used as controls. After 8 months the sheep were killed and the joints examined radiologically and histologically. Osteophytes were seen on all the condylar radiographs. Histologically, there were proliferative changes in both the condylar and temporal surfaces adjacent to the disc perforations.
