연구실 소개
현승재 교수의 연구실은 척추변형 및 척추수술 후 합병증, 특히 상부관절성경화증(PJK)과 상부관절성실패(PJF)의 발생 기전과 예방 전략에 중점을 두고 있습니다. 영상 진단을 활용한 부비경화근의 비율 변화 및 지방변성 정도 평가를 통해 척추 안정성과 임상 결과 간의 연관성을 규명하고 있으며, 특히 PSO 수술 후 장기적 결과 개선을 위한 최적의 체중선 조정 전략을 모색하고 있습니다. 이는 환자의 삶의 질 향상과 수술적 합병증 감소에 기여할 수 있는 임상적 의미가 큽니다.

Intraoperative or postoperative complications are relatively common following PSO. Most late-onset complications in PSO patients were related to PJK and instrumentation failure. Correcting the C7 plumb line value with minimal operative complications seemed to lead to better clinical results.
The purpose of this review is the current understanding of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) following adult spinal deformity (ASD) surgery. We carried out a systematic search of PubMed for literatures published up to September 2017 with "proximal junctional kyphosis," "proximal junctional failure," and "adult spinal deformity" as search terms. A total of 98 literatures were searched. The 37 articles were included in this review. PJK is multifactorial in or

Quantitative analysis using magnetic resonance imaging and computed tomography scanning showed differences in paraspinal muscle volume and fatty degeneration between patients with DLK and healthy volunteers. This evaluation method may be useful for measuring the extent of paraspinal muscle degeneration.
The trend of excellent radiologic outcome was observed for IP≥CP>CA. Plating may play a key role in the support of anterior height. As a result, plating prevents segmental kyphosis and subsidence and promotes bone fusion. Although the overall clinical outcomes were not different among the 3 groups, except for arm pain, more favorable trends regarding clinical outcome were observed for CP≥IP>CA.

The results suggest that the loss of cervical ROM is time-dependent and plateaus by 18 months after surgery, with no further decreases thereafter.

The 0.5 mm lead aprons blocked just over one third of the radiation scattered towards the surgeon. Use of robotic-guidance in a minimally invasive approach provided for a reduction of 62.5% of the overall radiation the surgeon was exposed to during open conventional approach. We conclude that reduced radiation use (e.g. by using robotic guidance) is a more effective strategy for minimizing exposure to radiation than reliance on protection by lead aprons, and recommend utilization of practices an
