Cervical kyphotic deformity represents a difficult to treat pathology often arising from multiple factors including, but not limited to, traumatic injuries, degenerative changes, and ankylosing spondylitis. Furthermore, treatment of these deformities becomes increasingly difficult with any preexisting instrumentation. Currently, several options exist to treat these severe deformities, with the Smith-Petersen osteotomy and C-7 pedicle subtraction osteotomy being the most frequently used approaches. However, these techniques come with significant risk to the patient including nerve root injury as well as compression of the vertebral arteries. The authors here report on a series of 4 patients with rigid cervical deformity who underwent T-1 pedicle subtraction osteotomy. The authors review the relevant literature and provide a novel, less risky, and potentially more corrective approach for treating cervical deformities.

Study Design: Retrospective cohort study OBJECTIVES: The purpose of this study was to compare the 2-year radiological outcome and revision rates in patients with ASD treated with either PSO or PLIF, when PLIF was used to improve sagittal balance.
Methods: In 2016, PLIF was introduced at our institution as an alternative method when restoring lumbar lordosis. We analyzed two cohorts of patients with ASD undergoing either: PSO in 2010-2015 or PLIF in 2016-2020, retrospectively.

Objective: To confirm the effect of surgery on spinal column biomechanics and to provide theoretical support for the advantages and disadvantages of different surgical methods and their clinical efficacy.
Methods: 33 continuous patients with no significant difference in risk factors related to the mechanical complications were enrolled in this retrospective study. Sagittal parameters were measured in the pre-, post-operative and following-up lateral radiograph of spine.

Purpose: Three-column osteotomies (3COs), such as pedicle subtraction osteotomy (PSO) and vertebral column resection (VCR), are used to surgically correct rigid adult spinal deformity (ASD). While extensive research exists about complications associated with 3COs, there remains a paucity of studies analyzing risk factors for mortality following 3CO. We believe the mortality rate after 3-column osteotomy will be low with specific identifiable demographic or medical risk factors.

Article Synopsis
- The study investigates the effectiveness of two surgical treatments for Stage III Kümmell's disease without neurological deficits: percutaneous kyphoplasty (PKP) and pedicle subtraction osteotomy (PSO) combined with long-segment fixation (LSF).
- A total of 89 patients were treated, with results showing that the PKP group had quicker recovery metrics and lower disability scores post-surgery, while the PSO+LSF group achieved better spinal alignment corrections.
- Ultimately, both procedures were effective with similar complication rates, suggesting personalized treatment plans based on patient's condition and surgeon’s expertise are crucial.
