Kunihiro Oka 교수의 연구실은 저선량 CT를 활용한 3차원 뼈 모델링 기술과 맞춤형 하이드로우레오파이트 임플란트를 통한 정형외과 수술의 정밀도 향상을 연구하고 있습니다. 특히, 뼈의 해부학적 구조를 정확히 재현하고 기능적 회복을 도모하기 위한 비침습적 영상 분석 기술과 수술 전후의 실시간 3차원 운동 분석을 융합한 혁신적 접근을 선도하고 있습니다. 이는 선천성 전위성 비틀림 등 복잡한 정형외과 병변의 치료에 있어 임상적 정확도를 크게 향상시키는 데 기여하고 있습니다.

3D bone models constructed from low-radiation dose CT data demonstrated the same level of accuracy as those constructed from normal-radiation dose data. The present simulation system can produce 3D bone models with one-thirtieth of the normal radiation dose in the forearm.
Customized hydroxyapatite implants are helpful for accurate correction and good functional results.
Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.
Our method resulted in a good diagnostic rate, even when using a relatively small amount of data.
Abstract Attempts to separate congenital radioulnar synostosis and restore forearm rotation had been disappointing until a new mobilization technique was developed by Kanaya and colleagues using free vascularized fascio‐fat graft interposition. This technique provides a functional rotation arc, but postoperative forearm motion is difficult to evaluate given the inaccuracies in determining the range of motion and rotational axis using conventional x‐rays or computed tomography. This study represe
This report describes the clinical application of an ultrasonic aspirator for endoscopic neurosurgery. Eight patients with intraventricular hematoma with complete tamponade of the ventricular system and marked hydrocephalus were treated with the ultrasonic aspirator for endoscopic neurosurgery. Clinical evaluation and neuroimaging studies were obtained for one month. Removal of hematoma was confirmed on follow-up imaging. The ultrasonic aspirator is operated by electrostriction transducer on low
Scaphoid nonunion causes abnormal wrist kinematics and typically leads to carpal collapse and subsequent degenerative arthritis of the wrist. However, the natural history, including carpal collapse and degenerative arthritis of scaphoid nonunion, may vary at different fracture locations. This article reviews recent biomechanical studies related to the natural history of scaphoid nonunion. In the distal-type fractures (type B2 in Herbert classification), where the fracture located distal to the s
