A Titanium Implant for Interbody Fusion in Degenerative Lumbar Disk Disease

Abstract

Surgery is sometimes needed in the management of patients suffering from degenerative lumbar disk disease. Posterior diskectomy alone without stabilization of the motion segment often fails to relieve back pain. Scarring around and possible devascularization of the nerve root is sometimes responsible for recurrent and persistent symptoms. Posterolateral fusion has not been shown to control the motion segment effectively. On the other hand, anterior diskectomy with interbody fusion avoids these problems and effectively eliminates the motion segment in a high percentage of cases [1]. There are however inherent difficulties with anterior interbody fusion using autogenous iliac bone graft, including problems with harvesting enough good quality grafts, especially in cases involving revision, multi-level fusion, osteoporosis, and in ethnic groups such as the Chinese who often have thin pelvises. Donor site complications are common, such as pain, fracture, hematoma, and wound drainage. The quality of the graft can also cause problems with graft extrusion, non-union, and early or delayed graft collapse. For these reasons, a search was begun for a graft substitute that would ideally be available in various sizes, be biocompatible, be strong enough to support the spine, have mechanical properties close to the normal lumbar motion segment, and preferrably allow biological fixation.
