A Carbon Fiber Implant to Aid Interbody Lumbar Fusion

Comparison of instrumented anterior interbody fusion with instrumented circumferential lumbar fusion

“…Kuslich et al [28] reported a 91% fusion rate, 84% pain relief and 91% functional improvement at 24 months' follow-up using the BAK method of lumbar interbody fusion. Other authors [1,2,3,10,16,50,52] have reported more than 70% satisfactory clinical results with instrumented interbody fusion. Our patients had a 72% rate of clinical satisfaction with ALIF and 74% with circumferential fusion (PLIF) using subjective scores, and 79.5% and 80% clinical satisfaction using the Oswestry Disability Index.…”

“…A pain drawing was used for them to show the site of pain. They were asked to describe the characteristics of the pain, which was scored as: numbness (4), pin prick (3), burning (2), and/or stabbing (1).…”

Lumbar lateral interbody cage with plate augmentation: in vitro biomechanical analysis

“…Interbody fusion cages are used to stabilize the spine and to promote bony fusion between two vertebrae [2]. A main requirement in achieving the fusion is the need to obtain adequate stability and maintain it during a period sufficient for bone consolidation [11,12,17].…”

Anterior lumbar interbody fusion with threaded fusion cages and autologous bone grafts

“…This has resulted in the use of different materials such as bioceramics, corals, allografts, and constructs made from carbon fibre or metal. The results of fusions performed using these techniques are inconsistent and not convincing [1,5,9,10].…”

“…mentation has increased. Brantigan developed a carbon-fibre cage for posterior application and reported fusion rates of up to 100% [1]. Stender et al reported good results in 76% of their patients with a cobalt-chrome molybdenum implant for anterior fusion; however, the subjectively reported results for return to work and pain reduction showed good results in only 68% [17].…”
