GRAF SPINAL STABILISATION OF THE LUMBAR SPINE – LONG TERM RESULTS



Abstract

The Graf technique of spinal stabilisation of the lumbar spine is a semi rigid pedicular screw system without spinal fusion. It is an unique system, which has both proponents and opponents. The mechanism of stabilisation is as yet not fully understood.

This retrospective study looks at the long term results of 35 patients with a minimum follow up of 4 years.

The age ranged from 35 years to 76 years with an average of 60 years of age.

89 percent of the patients improved considerably and no further surgery was performed on any of them. The complication rate was minimal. The Graf spinal system merits further study with prospective trials comparing it with pedicular screws and spinal fusion. The scientific basis should be established, as many surgeons are doubtful about this system.

The abstracts were prepared by Professor Jegan Krishnan. Correspondence should be addressed to him at the Flinders Medical Centre, Bedford Park 5047, Australia.
