The objective was to investigate the levels of TWIST1 in normal and OA cartilage and examine its role in regulating gene expression in chondrocytes. Human cartilage tissues and chondrocytes were obtained at autopsy from normal knee joints and from OA-affected joints at the time of total knee arthroplasty. TWIST1 expression was increased in human OA knee cartilage compared to normal knee cartilage. TWIST1 induced matrix metalloproteinase 3 (MMP3) expression without direct binding to MMP3 promoter and increased the 5-hydroxymethylcytosine (5hmC) level at the MMP3 promoter. The effect of TWIST1 on expression of TET family (TET1, 2 and 3) was measured in stable TWIST1 transfected TC28 cells, and TET1 expression was up-regulated. TWIST1 dependent upregulation of Mmp3 expression was suppressed in Tet triple KO fibroblast derived from mouse ES cells. Increased TWIST1 expression is a feature of OA-affected cartilage. We identified a novel mechanism of catabolic reaction where TWIST1 up-regulates MMP3 expression by enriching 5hmC levels at the MMP3 promoter via TET1 induction. These findings implicate TWIST1 as an important factor regulating OA related gene expression. Clarifying epigenetic mechanisms of 5hmC induced by TWIST1 is a critical molecule to understanding OA pathogenesis.

JOURNAL OF ORTHOPAEDIC SCIENCE 22 ( 1 ) 121 - 126 2017年1月

記述言語：英語出版者・発行元：SPRINGER JAPAN KK

Background: It has been reported that the national incidence of developmental dysplasia of the hip (DDH) has decreased in Japan. This is because of prevention activities after birth since around 1970. However, cases of late-diagnosed DDH have still been noted in some children's hospitals. There has been no recent survey of DDH in Japan. The purpose of this study was to investigate the current epidemiology of DDH using a comprehensive nationwide survey.
Methods: A questionnaire was sent to orthopedic surgeons in 1987 facilities nationwide, who were asked to complete and return a survey card on each DDH patient treated between April 2011 and March 2013.
Results: A total of 783 (39%) facilities completed and returned the card. Of these, 79% reported no cases of DDH-related dislocation over the 2-year period, while the remaining facilities reported 1295 cases. The characteristics of children diagnosed with DDH-related dislocation were as follows: girls (89%), left side involvement (69%), bilateral involvement (4%), positive family history (27%), first-born (56%), and pelvic position at birth (15%). Seasonal variation showed an increase in DDH incidence among those born in the winter. Overall, 199 cases (15%) were diagnosed at >1 year of age, and these included 36 cases diagnosed very late, at >3 years of age. The majority of the 199 cases of late diagnosis had received earlier routine screening at <1 year of age.
Conclusion: The characteristics of the children diagnosed with DDH nationwide were similar to past data from local regions. However, many children were diagnosed late (>1 year of age), particularly in the more populous regions. The findings identify a need for improved early routine screening for DDH in Japan.

Background: We investigated whether the calcar femorale, a cortical septum in the region of the lesser trochanter of the femur, correlates with results of femoral stem implantation in patients with osteoarthritis of the hip secondary to developmental dysplasia using computed tomography. Methods: This retrospective study included 277 hips (41 males and 236 females
age, 37 to 92 years) of patients who had presented to Okayama Medical Center with hip pain. Of these, a total of 219 hips (31 males and 188 females) had previously undergone total hip arthroplasty. According to the Crowe classification, 147 hips were classified as Crowe grade I, 72 hips as Crowe grade II– IV, and 58 hips as normal. Results: The calcar femorale was identified in 267 hips (96.4%). The calcar femorale was significantly shorter and more ante-verted in Crowe grade II–IV hips than in Crowe grade I or normal hips. Significant differences in the shape of the calcar femorale were found according to the severity of hip deformity. Three stem designs were analyzed: single-wedge (59 hips), double-wedge metaphyseal filling (147 hips), and modular (13 hips). Single-wedge stems were inserted more parallel to the calcar femorale rather than femoral neck anteversion, while other types of stems scraped the calcar femorale. Conclusions: The angle of the calcar femorale differs according to the severity of hip deformity, and the calcar femorale might thus serve as a more useful reference for stem insertion than femoral neck anteversion in total hip arthroplasty using a single-wedge stem.

健常者8名(男性6名、女性2名、20歳代)を対象とし、2種類の計測法によって関節可動域(ROM)を計測した。理学療法士(PT)により角度計を用いて徒手的にROM計測を行った(徒手計測法)。考案した新しい計測法として、3Dスキャナーによって体表の撮像を行い、そこから得られた三次元データを用いてコンピューター上でROM計測を行った(3Dスキャナー計測法)。被験者ごとのROMの標準偏差は、全ての関節肢位において3Dスキャナー計測法では徒手計測法と比較し検者間における標準偏差は有意に小さかった。平均最大測定値差は、標準偏差と同様に全ての関節肢位において3Dスキャナー計測法では徒手計測法と比較して有意に小さかった。徒手計測法、3Dスキャナー計測法の級内相関係数(ICC)は、全ての関節において3Dスキャナー計測法のほうが高く、検者間誤差は小さかった。平均計測時間は、肘関節、足関節ともに3Dスキャナー計測法のほうが有意に計測に時間を要した。
