“…The post-operative loss of correction in our study was 3.3°(range 0°-21°).This is comparable with the results of combined procedures reported by Knop et al [20], Verlaan et al [40], and Lange et al [24]. We are aware of some more loss after the IR, but in cases with successful anterior fusion this should be moderate.…”

“…There was no sufficient fusion to the fracture area. d After IR there was an additional loss of correction and intevertebral fusion occurred in the posterior intervertebral area according to several authors [7,11,14,17,19,20,24,25,29,35,36,38,40]. The six patients with a partial fusion showed the non-fusion area between the graft and the fractured endplate.…”

“…Briem et al [3,4] reports anterior fusion rates of 77 and 65%. Lange et al [24] reports 83% of anterior intervertebral fusion as diagnosed by X-rays. Dickman et al [8] refers to 95-99% fusion rates in a metaanalysis, but several of the studies he included did not define fusion criteria.…”

Patients with fractures from the 11th thoracic to the 5th lumbar vertebra had a reconstruction of the anterior column with monocortical iliac crest autograft by using a single dorsal approach. The loss of correction was observed using X-rays pre-and post-operatively, at 3 months and after implant removal (IR). Successful fusion was assessed using computed tomography after the implant removal. To assess the loss of correction and intervertebral fusion rate of this technique. There are still controversial discussions about the treatment modalities of spine lesions, especially in cases of burst fractures. Dorsal, combined and ventral procedures are reported with different assets and drawbacks. We want to present a method to restore the weightbearing capability of the anterior column using a single dorsal approach. From 2001 to 2005, a total of 100 patients was treated with this technique at our department. Followup examination was possible in 82 patients. The X-rays and CT scans were proofed for loss of correction and fusion rate. The anterior column has been restored using a monocortical strut graft via a partial resection of the lamina and the apophyseal joint on one side to access the disc space. The dorsal reduction has been achieved using an angular stable pedicle screw system. The mean follow-up time was 15 months (range 8-39); 67 patients had a CT scan at follow-up and 83% showed a 360°fusion. The average post-operative loss of correction was 3.3°(range 0-21). The average duration of operation was 192 min (range 120-360) and the mean blood loss was 790 ml (range 300-3,400 ml). Regarding the complications we did not have any deep wound infections. We had two epidural haematomas postoperatively with a neurological deterioration that had to be revised. We were able to decompress the neurological structures and restore the weight-bearing capability of the anterior column in a one-stage procedure. So we think that this technique can be an alternative procedure to combined operations regarding the presented radiological results of successful fusion and loss of correction.

“…Although considerable literature about treatment of fractures of the thoracolumbar region exists [10,13,17], very little data were found about the special problem of cage subsidence in osteoporotic or metastatic bone [18,26]. Nevertheless, every surgeon knows about the problem of cage subsidence or loosening which is linked to bad bone quality and a too stiff construct compared with the bone and its much lower e-module [23].…”

Anterior vertebroplasty of adjacent levels after vertebral body replacement

The aim of this study was to evaluate the feasibility of a new method, which should help to avoid cage subsidence after vertebrectomy in short fusions. After implantation of an extendable vertebral body replacement (VBR) the two adjacent endplates to the fractured or destroyed vertebra were augmented with bone cement using the anterior approach in 20 patients with short circumferential fusion. All patients were followed up for 2 years clinically and radiographically. X-rays were reviewed for kyphosis, cage subsidence, presence of a solid fusion mass and instrumentation failure. Changes in every day activities (Oswestry Disability Index-ODI) and visual analogue scale (VAS), pain score, as well as techniquerelated complications were examined. The mean amount of kyphosis correction was 12.8°(±6.4°) and changed by only 0.3°(±0.4°) until last follow-up. Pain (VAS) and ODI scores were significantly improved and did not change until last follow-up. In all but two cases, the authors observed solid union with incorporation of the cage. No surgeryrelated complications were recorded. In one case revision was advised because of non-union due to septic loosening. The augmentation of the adjacent vertebras after anterior VBR provides an enhancement of the interface between cage and vertebra in cases with poor bone quality and in revision surgery. The technique is simple and safe, as the needles can be placed under visual control. Cement augmentation of the endplates may reduce interbody device subsidence.
