The effect of malnutrition on outcomes after posterior lumbar fusion (PLF) remains understudied. This study analyzes the effect of malnutrition across a comprehensive range of body mass index (BMI) on complications after PLF. ⋯ Our analysis indicates that malnutrition may independently increase PLF complication risk. Surgeons may consider preoperative optimization for malnutrition patients to reduce complication risk.

Primary mobile vertebral column sarcoma is an exceedingly rare malignancy. Although primary tumor resection has been reported to prolong survival in patients with metastatic bone sarcoma, whether primary tumor resection in patients with advanced primary mobile vertebral column sarcoma is associated with survival remains unclear owing to the rarity of this pathological entity. ⋯ To our knowledge, this is the first study to indicate that surgical resection for advanced primary mobile vertebral column sarcoma does not have a positive impact on survival.

Direct pars repair with cannulated screws in adults: A case series and systematic literature review.
Lumbar spondylolysis occurs in 5%-8% of adults. This study aimed to report clinical and radiographic outcomes of direct pars repair in adults with lumbar spondylolysis. ⋯ Lumbar spondylolysis treatment with open fracture reduction and direct pars repair with cannulated screws in adults is safe and may result in mechanical back/radicular pain relief, even in the absence of radiographic fusion.

Metastatic epidural spinal cord compression (MESCC) may lead to walking disability. The effect of regaining gait ability on the life expectancy of cancer patients is still unknown. To explore this issue, we evaluated the effect of gait ability recovery in nonambulatory patients after treatment for a metastatic spinal tumor. ⋯ Patients who regained their gait ability after treatment for MESCC tended to live longer than those who did not, indicating that recovery of gait ability by patients with cancer is associated with improved life expectancy.

Oblique lumbar interbody fusion (OLIF) is known as a minimally invasive technique for disc space augmentation. Motor weakness after OLIF has been known to occur in some cases. This study aimed to report the incidence and potential risk factors for motor weakness following OLIF. ⋯ In our study, vertebral osteophyte length was found to be a potential risk factor for motor weakness after OLIF. For patients with long osteophytes, additional laminectomy following OLIF or another surgical approach for direct decompression should be considered.
