Complications and surgical revision for failed disc arthroplasty
John P. Kostuik,
Volume 4, Issue 6 (Supplement), Pages S289-S291 (November 2004)
Kostuik JP. Complications and surgical revision for failed disc arthroplasty. Spine 2004;4:289 – 91.
If disc arthroplasty fails, there are three options: posterior fusion; revision replacement; and, anterior fusion
On revision surgery, Santos, et al., state, “Revision surgery for a failed disc arthroplasty is life threatening. Dealing with the scarring around the great vessels is the main challenge. Indeed, the location of vital vascular structures may make it altogether impossible to perform such anterior abdominal exposures.”

Currently, the major deficiency in the rules and experimental design of the cervical and lumbar prospective randomized trials is that they do not differentiate between prostheses that are difficult or easy to revise.

Proper sagittal alignment allows for the devices to function as they are intended with maximum motion. This also reduces the forces on the implant and on the posterior elements. As mentioned above, adequate posterior vertebral height is mandatory, and unless the disc height is unusually high, typically the entire posterior annulus is loosened or transected, as well as the PLL.

Revision strategies for failed total disc arthroplasty can be planned as a posterior fusion, leaving the total disc replacement device in place, or by way of anterior removal with subsequent anterior fusion or revision replacement of the prosthesis.
Insertion of an antiadhesive membrane
Another strategy to make vascular dissection easier and safer is to use an anti-adhesive membrane (eg, Gore-Tex, W. L. Gore & Associates, Inc., Newark, Delaware). This membrane is inserted between the prosthesis and the great vessels during the primary surgery. In a revision surgery, the vessels can more easily be dissected from the anterior spine and mobilized to the right side Another way to reduce adhesions between the great vessels and the spine is to keep manipulation of the vessels to a minimum with gentle surgical technique, thus minimizing fibrosis between the vessels and the spine.
When the decision is made to explant the device and fuse the segment, the revision intervention should ideally be performed from an oblique or lateral approach to avoid significant manipulation of the great vessels, which is especially critical in the L4-5 area. By performing oblique or lateral partial corpectomy, even prostheses with a fixation keel can be removed without significant vascular manipulation.
Explantation of ProDisc with subsequent anterior fusion (complication occurred due to trauma) A 39-year-old woman had been treated with implantation of a ProDisc prosthesis at the L5-S1 level. Three months after surgery, the patient fell on her buttocks, causing an impaction fracture of the upper end plate of the prostheses into the L5 vertebral body (Fig. 4A, B). Conservative treatment for 3 more months could not reduce the level of her persistent increased low back pain. Six months after implantation, revision surgery with implant removal and anterior cage and (pyramid?) plate fixation was performed (Fig. 4C, D). After this surgery, her low back pain was completely resolved.

Failure of bone healing of the fusion (“pseudo-arthrosis”) can occur in 5 to 40% of cases, depending on the specific surgical technique used and the patient’s individual risk factors. If metallic implants were used and the fusion does not heal, this will eventually result in loosening or breakage of the screws or rods, as they are not meant to be relied upon to stabilize the spine indefinitely.
[Thus, you can not leave the device in, as it will provide zero stability to the posterior instrumentation.]
Lumbosacral Fusion: Cages, Dowels and Pedicle Screws
Rick C. Sasso, M.D.
The recent interest in performing lumbar interbody arthrodesis with use of cages is attributable to three factors according to McAfee. 64 First, the rate of failure associated with use of bone graft alone is high. Second, the rate of failure associated with use of posterior pedicle-screw instrumentation is high. And finally, the rate of success associated with use of stand-alone anterior fusion cages and autogenous bone graft is high. This obviates the need to perform a 360 (combined anterior and posterior) lumbar arthrodesis with use of posterior instrumentation. Interbody fusion cages have had a tremendous effect on anterior fusion. The rates of fusion after anterior interbody arthrodesis have improved from Stauffer and Coventry's90 56% to 93% with the use of the BAK titanium cage.60
