Surgical approaches to pathologies of the L5 vertebra constitute a significant challenge. Our aim was to review the efficacy and safety of the surgical approaches to L5 corpectomy and reconstruction across the range of presenting pathology. ⋯ Where there is clinical and circumstantial equipoise regarding the choice of surgical approaches for a L5 corpectomy, this review indicates a reported mean blood loss of 2265 ml (400-4700 ml), high fusion rates (94%) and relatively low complication rates (11.7%). It is difficult to make direct comparisons between approaches due to small case series, the variability in primary pathology, clinical intent and surgeon experience.

Review Case Reports
Intradural extramedullary spinal metastasis of renal cell carcinoma: illustrative case report and comprehensive review of the literature.
Literature review. ⋯ The 22-year interval from diagnosis of primary RCC to intradural metastasis is the longest latency reported in the literature. Intramedullary metastases tend to have a younger age at diagnosis and shorter interval from diagnosis of primary RCC compared to extramedullary lesions.

Vertebral hemangiomas (VH) account for 2-3% of all spinal tumors. The majority is incidentally found on radiographic studies: 1% present with pain and/or neurologic deficits. We report our experience with the multidisciplinary management of aggressive symptomatic thoracic VH by concomitant intraoperative sclerotization with sodium tetradecyl sulfate (STS), vertebroplasty, posterior decompression (with/without fusion) and surgical resection in a hybrid operating room (HR) equipped with a rotational scanner and a radiolucent operating table. ⋯ The single-stage multimodal management of aggressive symptomatic VH is safe and effective. It allows for a direct intraoperative sclerotherapy combined with maximal tumor resection, resulting in reduced blood loss. The use of STS as a direct intraoperative sclerotizing agent is safe and reliable.

Ureteric injuries are rarely associated with spinal trauma with an incidence of less than 1%. Missed injuries can lead to urinoma collection, urosepsis and even death. ⋯ We report for the first time a post-traumatic urinoma secondary to ureteric injury clinically mimicking spondylodiscitis. Clinicians need to be aware of the possibility of ureteric injury in hyperextension lumbar fractures occurring in ankylosing spondylitis and treat them early to avoid urological complications.

L5 pedicle subtraction osteotomy (PSO) is a demanding technique; thus, PSOs are usually performed at the L3/L4 level to correct the lack of lumbar lordosis. Mid- to long-term improvements in clinical outcomes after L5 PSO are unknown. We aimed to determine the efficacy and safety of L5 PSO for rigid kyphosis deformities. ⋯ L5 PSO for L4-5/L5 kyphosis deformities resulted in adequate correction and ODI improvement, which were maintained up to 5 years postoperatively. The surgical invasiveness, complication rates, and long-term prognosis associated with L5 PSO were similar to those of PSOs performed at other levels.
