Takayoshi Shimizu 교수의 연구실은 척추디스크 및 척추정열의 생체역학적 원리와 임상적 결과 개선을 중심으로 한 척추외과 임상 연구를 수행하고 있습니다. 특히 척추간판 유합술에서의 생체활성 PEEK 임플란트 개발, 척추후방유합술의 비침습적 분해술 기법, 그리고 척추전방유합술 후의 전신 체중 분포 및 보상 메커니즘 분석에 초점을 맞추고 있습니다. 환자의 전신 체중 분포와 척추 정렬 간의 상관관계를 정량적으로 분석함으로써 수술 전 예측 가능성을 높이고, 장기적인 임상 결과를 향상시키는 데 기여하고 있습니다.

LIF with indirect decompression for degenerative lumbar disease with severe canal stenosis provided successful clinical outcomes, including restoration of disc height and indirect expansion of the thecal sac. Severe canal stenosis diagnosed on preoperative MRI itself is not a contraindication for indirect decompression surgery.
The TiO2-coated bioactive PEEK implant demonstrated better fusion rates and bone-bonding ability than did the uncoated PEEK implant in the canine anterior cervical fusion model. Bioactive PEEK, which has bone-bonding ability, could contribute to further improvements in clinical outcomes for spinal interbody fusion.
ASD patients with increased CrSVA-H, which represents cranio-hip anterior imbalance, demonstrated a higher prevalence of LE compensation, especially knee flexion, compared to those with neutral and posterior shift of CrSVA. PT represents the extent of LE compensation in patients with spinal sagittal malalignment. Using the cutoff value of PT determined in this study, surgeons can preoperatively estimate the extent of LE compensation without obtaining a full-body radiograph.

The CT-confirmed fusion rate of OCF was 77.2% over an average 89.7-month follow-up. Compensatory sagittal alignment change can occur in the unfused subaxial segments in conjunction with the alignment change in the instrumented OC segments, whereas the horizontal gaze was maintained. Strong consideration for the intraoperative measurement of the OC2A should be given during OCF to minimize both early and long-term complications.Level of Evidence: 4.
