• Kawamura I., Tominaga H., Tokumoto H., Sakuma D., Sanada M., Ogura T., Taniguchi N. . Removal of a migrated acupuncture needle from the cervical spinal canal with removal confirmation by cone-2023 · 記述言語： 英語 出版者・発行元： Trauma Case Reports Background: Acupuncture has become one of the most popular alternative medical treatments in the world. However, if the needle is inserted incorrectly into the body, various adverse events can occur and, in such cases, the needle should be removed. Acupuncture needles are very thin and fragile, making them difficult to detect and to confirm breakage or residual needle fragments during surgery. We report a case of a patient's self-placed acupuncture needle migrating into the cervical spinal canal and its surgical removal. We used cone-beam computed tomography in the hybrid operating room to confirm that the needle was removed in its entirety. Case presentation: A 37-year-old man presented with neck pain and gait disturbance. While he was self-acupuncturing, an acupuncture needle accidentally broke, and the remaining part of the needle penetrated and made contact with the cervical spinal cord. Cervical spine radiographs showed a metallic foreign body between the C1 and C2 spinous processes in the direction of the anterior cervical spine. Computed tomography images revealed that the acupuncture needle was penetrating the spinal canal and was in contact with the cervical cord. The acupuncture needle was removed under general anesthesia. The use of cone-beam computed tomography in the hybrid operating room allowed intraoperative confirmation that there was no breakage during needle removal, and no needle fragments were left behind. His symptoms disappeared without any complications after the operation. Conclusion: To the best of our knowledge, this is the first report of the removal of an acupuncture needle that migrated into the cervical spinal canal using cone-beam computed tomography in a hybrid operating room. Intraoperative cone-beam computed tomography is useful in patients with small, fragile foreign bodies for confirmation of the location of the object and to check for the presence of residual fragments.

Correlation between Acetabular Anteversion with a False-Profile View and Spinopelvic Param2023 · 担当区分： 筆頭著者, 責任著者 記述言語： 英語 出版者・発行元： 一般社団法人 日本脊椎脊髄病学会 Introduction: Studies describing the relationship between the hip and spine have reported that corrective spinal surgery for adult spinal deformity (ASD) affects the orientation of the acetabulum. However, the extent to which spinal correction in ASD affects acetabular anteversion in the standing position is unclear, especially after total hip arthroplasty, for which dislocation is a concern. The purpose of this study was to evaluate changes in anterior acetabular coverage in the upright position due to extensive correction surgery for ASD. Methods: Thirty-six consecutive patients who had undergone spinal corrective surgery from the thoracolumbar region to the pelvis were enrolled and evaluated. The ventral-central-acetabular (VCA) angle and anterior acetabular head index (AAHI) were measured with a false-profile view to evaluate the relationship between acetabular anteversion in the standing position and spinopelvic parameters before and after surgery. The spinopelvic parameters measured included thoracic kyphosis, pelvic incidence, pelvic tilt (PT), sacral slope, lumbar lordosis (LL), sagittal vertical axis, and global tilt. Results: The VCA angle and AAHI were significantly increased after spinal deformity correction (p<0.001). The changes in LL and PT were correlated with the VCA angle (LL: right, ρ=0.56; left, ρ=0.55, p<0.001; PT: right, ρ=−0.59; left, ρ= −0.64, p<0.001) and AAHI (LL: right, ρ=0.51; left, ρ=0.58, p<0.01; PT: right, ρ=−0.52; left, ρ=−0.59, p<0.01), respectively. Linear regression analysis revealed that a 10° increase in LL results in 1.4°-1.9° and 1.6%-2% increases in the VCA angle and AAHI, respectively. Conclusions: Surgical correction for ASD significantly affects sagittal spinopelvic parameters, resulting in increased acetabular anteversion. The anterior coverage of the acetabulum in the postoperative standing position could be predicted with the intraoperatively measured LL, and evaluation using a false-profile was considered useful for treating ASD, particularly in patients after total hip arthroplasty.
