To determine the efficacy and poor prognostic factors of posterolateral full-endoscopic debridement and irrigation (PEDI) surgery for thoraco-lumbar pyogenic spondylodiscitis. ⋯ PEDI treatment is an effective, minimally invasive procedure for pyogenic spondylodiscitis. However, a large intervertebral abscess space could cause instability at the infected spinal column, leading to prolonged or recurrent infection after PEDI. In cases with a large abscess cavity with or without vertebral bone destruction, endoscopic drainage alone may have a poor prognosis, and spinal fixation surgery could be considered.

Posterior instrumentation is the state-of-the-art surgical treatment for fractures of the thoracic and lumbar spine. Options for pedicle screw placement comprise open or minimally invasive techniques. Open instrumentation causes large approach related muscle detachment, which minimally invasive techniques aim to reduce. However, concerns of accurate pedicle screw placement are still a matter of debate. Beside neurological complications due to pedicle screw malplacement, also affection of the facet joints and thus motion dependent pain is known as a complication. The aim of this study was to assess accuracy of pedicle screw placement concerning facet joint violation (FJV) after open- and minimally invasive posterior instrumentation. ⋯ FJV is more likely to occur in percutaneously placed pedicle screws. Additionally, higher grade FJV's occur after percutaneous instrumentation. However, in the thoracic spine we didn't find a significant difference between open and percutaneous technique. Our results suggest a precise consideration concerning surgical technique according to the fractured vertebrae in the light of the individual anatomic structures in the preop CT.

Spinal chondrosarcomas are rare malignant osseous tumors. The low incidence of spinal chondrosarcomas and the complexity of spine anatomy have led to heterogeneous treatment strategies with varying curative and survival rates. The goal of this study is to investigate prognostic factors for locoregional recurrence-free survival (LRFS) and overall survival (OS) comparing en bloc vs. piecemeal resection for the management of spinal chondrosarcoma. ⋯ Although in our study en bloc and GTR were associated with improved survival, heterogenous and complex spinal presentations may limit total resection. Therefore, the surgical management should be tailored individually to ensure the best local control and maximum preservation of function.

Longer hospital length of stay (LOS) has been associated with worse outcomes and increased resource utilization. However, diagnostic and patient-level factors associated with LOS have not been well studied on a large scale. The goal was to identify patient, surgical and organizational factors associated with longer patient LOS for adult patients at a high-volume quaternary spinal care center. ⋯ This large-scale study taking into account diagnostic categories identified several factors associated with patient LOS. Future interventions should target modifiable factors to minimize LOS and guide hospital resource allocation thereby improving patient outcomes and quality of care and decreasing healthcare-associated costs.
