Acute Renal Infarction After Lateral Lumbar Interbody Spinal Fusion for Kyphoscoliosis

MINIMALLY INVASIVE LUMBAR ARTHRODESIS AND PERCUTANEOUS PEDICLE SCREWS: A SYSTEMATIC REVIEW

ABSTRACT A systematic review of the literature was performed in order to organize, evaluate, and select evidences available about the safety and efficacy of minimally invasive percutaneous arthrodesis with percutaneous pedicle screws in the treatment of patients with degenerative disc disease (and other spinal pathologies) as compared to conventional arthrodesis. PubMed, EMBASE and Cochrane Library databases were consulted to locate clinical trials and case reports/case series published in English between 2014 and 2019. After selection according to the inclusion/exclusion criteria, 21 of the 197 articles identified were chosen for a complete reading and used for the present review. Although the level of evidence of most of the studies included made the demonstration of efficacy and superiority among the surgical techniques reviewed difficult, the findings related to the minimally invasive procedure indicate a safe and reliable approach for the treatment of lumbar diseases. Level of evidence II; Systematic review of literature.

Delayed hardware complication after lateral retroperitoneal lumbar surgery: an unusual case of painless hematuria

Lateral approaches to the spine are becoming increasingly popular methods for decompression, restoration of alignment, and arthrodesis. Although individual cases of intraoperative injuries to the renal vasculature and the ureters have been documented as rare complications of lateral approaches to the spine, the authors report the first known case of postoperative renal injury due to the delayed extrusion of the screw of a lateral plate/screw construct directly into the renal parenchyma. The migration of the screw from the L1 vertebra into the superior pole of the left kidney occurred nearly 5 years after the index procedure, and presented as painless hematuria. A traditional left-sided retroperitoneal approach had been used at the time of the initial surgery, and the same exposure was used to remove the hardware, which was done in conjunction with general surgery and urology.
