当科で初回THA(人工股関節全置換術)を行った72例(男性12例、女性60例、手術時平均年齢62歳)を対象に、CT based navigationとCT free navigationにおけるcup設置精度を比較検討した。CT based naviは無作為にFluoro navi(fluoro群36例)とLandmark navi(landmark群36例)に割り当てて使用し、CT free navi(CT free群72例)はCT based naviと同時に併用した。その結果、cup設置精度はfluoro群がlandmark群、CT free群に比べ外方開角、前方開角ともに精度が高かった。また、サブグループ解析の結果からFluoro naviは患者因子の影響を受けていなかったが、Landmark naviは骨盤傾斜の大きな症例で前方開角の精度が低下し、骨棘のある症例では外方開角の精度が低下する傾向が示された。CT free naviでは、骨棘のある症例で外方開角および前方開角ともに精度の低下がみられた。

Hip Joint 44 ( 2 ) 725 - 729 2018年8月

記述言語：日本語出版者・発行元：日本股関節学会

症例1は初診時46歳女性で、特に誘因なく左股関節痛が出現し、49歳時に手術加療を希望された。X線上CE角0°と形成不全股であり、左寛骨臼回転骨切り術(RAO)前に股関節鏡を施行し関節唇断裂に対して電気凝固メス(VAPR)でシュリンケージを施行した。その後、スロットカニューラからVAPRを出す際に先端を回転させ破損した。関節内には破損片は認められず、関節内洗浄後にイメージで確認したところ外側ポータルの関節外に破損片が認められた。イメージ下にコッヘルでつかんで除去できており、器具が破損したが摘出できた旨を説明し、予定通り4週後に左RAOを施行した。症例2は初診時39歳女性で、特に誘因なく両股関節痛が出現し、40歳時に右RAOを施行、左側も41歳時に手術を希望された。骨切り術前に股関節鏡を施行し関節唇断裂に対してVAPRでシュリンケージを施行したが、ポータルの入れ替え時に助手がVAPRを入れる際に完全に先端がカニューラ先から出る前に回転させ破損した。関節内には破損片は認められたが深部へと落ち込み、器具が到達できない部位へ移動した。2週後の再入院時のX線像で破損片の関節内の移動を認め、RAO手術時に一部関節包を切開し破片を回収した。予定とおり左RAOを施行し、摘出した破損片は2.5mmのサイズで破損部に合致し術後X線像からも完全に除去できたと考えられた。

Endoscopic Shelf Acetabuloplasty for Treating Acetabular Large Bone Cyst in Patient With Dysplasia. 国際誌

Kazuki Yamada, Dean K Matsuda, Hitoshi Suzuki, Akinori Sakai, Soshi Uchida

Arthroscopy techniques 7 ( 7 ) e691-e697 2018年7月

記述言語：英語掲載種別：研究論文（学術雑誌）

Acetabular bone cyst is usually associated with dysplastic secondary osteoarthritis of the hip joint. Acetabular reorientation osteotomy is one of the most common therapeutic options for treating patients with hip dysplasia. However, it may be too invasive for athletes and can also lead to some complications including intraoperative fracture and postoperative bone necrosis especially in patients with acetabular large bone cysts. Endoscopic shelf acetabuloplasty offers a less invasive option for athletic patients with dysplasia of severity greater than those indicated for isolated hip arthroscopy. This Technical Note demonstrates endoscopic shelf acetabuloplasty with bone grafting, simultaneously addressing a large bone cyst and acetabular undercoverage, as part of a comprehensive approach addressing chondrolabral pathology while restoring capsular integrity in an athlete with moderate dysplasia.

The Journal of arthroplasty 33 ( 1 ) 136 - 143 2018年1月

記述言語：英語掲載種別：研究論文（学術雑誌）

BACKGROUND: The accuracy of various navigation systems used for total hip arthroplasty has been described, but no publications reported the accuracy of cup orientation in computed tomography (CT)-based 2D-3D (two-dimensional to three-dimensional) matched navigation. METHODS: In a prospective, randomized controlled study, 80 hips including 44 with developmental dysplasia of the hips were divided into a CT-based 2D-3D matched navigation group (2D-3D group) and a paired-point matched navigation group (PPM group). The accuracy of cup orientation (absolute difference between the intraoperative record and the postoperative measurement) was compared between groups. Additionally, multiple logistic regression analysis was performed to evaluate patient factors affecting the accuracy of cup orientation in each navigation. RESULTS: The accuracy of cup inclination was 2.5° ± 2.2° in the 2D-3D group and 4.6° ± 3.3° in the PPM group (P = .0016). The accuracy of cup anteversion was 2.3° ± 1.7° in the 2D-3D group and 4.4° ± 3.3° in the PPM group (P = .0009). In the PPM group, the presence of roof osteophytes decreased the accuracy of cup inclination (odds ratio 8.27, P = .0140) and the absolute value of pelvic tilt had a negative influence on the accuracy of cup anteversion (odds ratio 1.27, P = .0222). In the 2D-3D group, patient factors had no effect on the accuracy of cup orientation. CONCLUSION: The accuracy of cup positioning in CT-based 2D-3D matched navigation was better than in paired-point matched navigation, and was not affected by patient factors. It is a useful system for even severely deformed pelvises such as developmental dysplasia of the hips.

Journal of orthopaedic science : official journal of the Japanese Orthopaedic Association 22 ( 6 ) 1084 - 1088 2017年11月

記述言語：英語掲載種別：研究論文（学術雑誌）

BACKGROUND: To compare the plain knee radiograph finding of tibial eminence width between knees with complete discoid lateral meniscus, incomplete discoid lateral meniscus, and normal lateral meniscus. MATERIALS AND METHODS: The study included 27 knees with discoid lateral meniscus, including 13 knees with complete discoid lateral meniscus and 14 knees with incomplete discoid lateral meniscus. A control group of 14 knees with normal lateral meniscus was also included. Tibial eminence width and the lateral slope angle of the medial tibial eminence were assessed using plain frontal knee radiographs. Individual differences in knee size were corrected by dividing tibial eminence width by tibial width to obtain the tibial eminence width percentage. RESULTS: Mean tibial eminence width and tibial eminence width percentage in the complete discoid lateral meniscus group was significant larger than other groups. Mean lateral slope angle in the complete discoid lateral meniscus group was significantly smaller than other groups. A tibial eminence width cut-off of 13.9 mm showed a sensitivity and specificity of 100% and 83%, respectively. A tibial eminence width percentage cut-off of 18.8% showed a sensitivity and specificity of 100% and 90%, respectively. A lateral slope angle cut-off of 27.1° showed a sensitivity and specificity of 71% and 83%, respectively. CONCLUSION: There were clear differences in tibial eminence width, tibial eminence width percentage, and lateral slope angle between the complete discoid lateral meniscus group and the other groups. The plain radiographic parameters identified by this study could be useful for complete discoid lateral meniscus screening. STUDY DESIGN: Clinical.

記述言語：英語掲載種別：研究論文（学術雑誌）

We retrospectively reviewed 29 hips in which intertrochanteric osteotomies were performed for severe slipped capital femoral epiphyses. Mean age at surgery: 12.6 years. Mean follow-up period: 6 years. At the final follow-up evaluation, one patient had coxalgia, and six hips showed a limited range of motion. A pistol-grip deformity was observed in 13 hips, osteoarthritis in two hips, and a bump existed in 19 hips on the latest radiographs. Gradual remodeling of the bumps was observed post-operatively in 22 hips. The mean α and β angles and offset α and β improved over time. The remodeling proceeded rapidly for 1 year post-surgery. We compared hips classified as β angles of ≥ 63° to < 63° at the final follow-up evaluation, the mean β angle 1 year post-surgery, and the mean ratio of improvement of the β angle per year from 1 year post-surgery to the final follow up, which differed significantly. Nearly all of the patients who underwent intertrochanteric osteotomies had residual morphologic abnormalities, but few had clinical symptoms. The β angle 1 year post-surgery and the ratio of remodeling of the bump from 1 year post-surgery to the final follow-up can be regarded as a potential predictor of morphologic results after intertrochanteric osteotomy.

Introduction Injuries to the medial meniscus (MM) posterior root lead to accelerated cartilage degeneration of the knee. An anatomic placement of the MM posterior root attachment is considered to be critical in transtibial pullout repair of the medial meniscus posterior root tear (MMPRT). However, tibial tunnel creation at the anatomic attachment of the MM posterior root is technically difficult using a conventional aiming device. The aim of this study was to compare two aiming guides. We hypothesized that a newly-developed guide specifically designed creates the tibial tunnel at an adequate position rather than a conventional device. Materials and methods Twenty-six patients underwent transtibial pullout repairs. Tibial tunnel creation was performed using the Multi-use guide (8 cases) or the PRT guide that had a narrow twisting/curving shape (18 cases). Three-dimensional computed tomography images of the tibial surface were evaluated using the Tsukada's measurement method postoperatively. Expected anatomic center of the MM posterior root attachment and tibial tunnel center were evaluated using the percentage-based posterolateral location on the tibial surface. Percentage distance between anatomic center and tunnel center was calculated. Results Anatomic center of the MM posterior root footprint located at a position of 78.5% posterior and 39.4% lateral. Both tunnels were anteromedial but tibial tunnel center located at a more favorable position in the PRT group: percentage distance was significantly smaller in the PRT guide group (8.7%) than in the Multi-use guide group (13.1%). Discussion The PRT guide may have great advantage to achieve a more anatomic location of the tibial tunnel in MMPRT pullout repair. Level of evidence IV.

Medial meniscus posterior root has an important role in the maintenance of knee articular cartilage. Although pullout repair of the medial meniscus posterior root tear has become a gold standard, it has several difficulties for suturing. We have developed a modified Mason-Allen suture technique using the FasT-Fix all-inside suture device combined with Ultrabraid. The present suture technique allows a strong grasping of the medial meniscus posterior horn for arthroscopic pullout repair.
