Posterior debridement and corpectomy via removal of the spinal canal’s lateral wall approach for infection after vertebral augmentation - a technique note and early outcome

Uploaded by Aurelia

Posterior debridement and corpectomy via removal of the spinal canal’s lateral wall approach (PDC-SCLWA) is evaluated as a technique for spinal infection after vertebral augmentation (SIAVA). The method is described as lateral wall resection for access, anterior lesion removal for debridement, and posterior wall preservation to support bone graft fusion, contrasting with conventional 360° decompression. Eight patients were treated, with symptoms alleviated and no recurrent infection during follow-up. Fusion rates at 3 months reached 93.8% for intervertebral bodies and 100% for posterolateral laminae.

The procedure is characterized as “lateral wall resection for access, anterior lesion removal for debridement, and posterior wall preservation for bone graft fusion.” This distinguishes it from conventional 360° decompression that involves extensive lamina and facet joint resection. Eight patients who underwent PDC-SCLWA were included. The mean surgical duration was 290.6±59 .2 minutes, with an average intraoperative blood loss of 775.0±389 .7 mL. Intraoperative dural laceration occurred in two patients. All patients’ symptoms were alleviated, and no recurrent infection was observed during follow-up. Seven patients received double titanium meshes, and one received an iliac bone graft. At 3 months postoperatively, the fusion rates of intervertebral bodies and posterolateral laminae we

FAQs

What problem does PDC-SCLWA address?

PDC-SCLWA addresses spinal infection after vertebral augmentation (SIAVA), a rare but severe postoperative complication that can cause major morbidity.

How is the PDC-SCLWA procedure designed?

The procedure follows a “lateral wall resection for access, anterior lesion removal for debridement, and posterior wall preservation for bone graft fusion” strategy.

What early outcomes were reported after PDC-SCLWA?

All eight patients had symptom alleviation, no recurrent infection was observed during follow-up, and 3-month fusion rates were 93.8% for intervertebral bodies and 100% for posterolateral laminae.
