Comparison of polyetheretherketone cages with femoral cortical bone allograft as a single-piece interbody spacer in transforaminal lumbar interbody fusion

Abstract: Both PEEK cages and FCAs are highly effective in promoting interbody fusion, maintaining postoperative disc space height, and achieving desirable clinical outcomes in patients who undergo TLIF with pedicle screw fixation. The advantages of PEEK cages include a lower incidence of subsidence and their radiolucency, which permits easier visualization of bone growth.

“…2,3 Compared with other interbody fusion techniques, TLIF is recognized to have advantages in safety and postoperative recovery, while achieving high rates of fusion. [3][4][5] These advantages stem from its lateral approach requiring exposure of only one facet joint and foramen, which provides sufficient exposure of the disc space for graft placement with minimal neural retraction.…”

“…7,9 By reinforcing PEEK with carbon fibers, the elastic modulus can be approximated to that of the cortical bone, which has been suggested to decrease stress shielding after spinal surgery compared to metal implants. 4,[10][11][12][13][14] The untreated surface of PEEK is bioinert and hydrophobic and it does not osseointegrate. 5 To convert the PEEK surface to be hydrophilic and osteoconductive, different techniques have been evaluated.…”

“…股関節は人体において体重を支える役割を有し,歩行時などにおいて体内の関節に作用する荷重による負担の 最も大きい部位である.したがって,股関節疾患は社会活動や日常生活に深刻な問題を及ぼす.近年の高齢化の 進行に伴い,骨や股関節における疾患は増加が予想されており,1990 年には 150 万人程度であった股関節疾患患 者数は,2025 年までに 300 万人を超えると予想されている (Cooper, et al, 1992) (Delaunay, et al, 2010) ).また,X 線を散乱するために画像診断が困難で あることに加え (Cutler, et al, 2007), CF/PEEK についての生 体適合性 に関する 障害は なく,耐 腐食性や耐薬品 性にも優 れている ) (Fujihara, et al, 2004).さらに,CFRP の有する様々な設計パラメータを用いることで,患者に最適なテー ラーメード人工股関節の開発が可能となる.したがって,寛骨臼サポートコンポーネントの形状,積層構成等の 設計パラメータが股関節における力学的挙動に及ぼす影響を数値解析により評価することは,寛骨臼サポートコ ンポーネントの設計に非常に有用であると考える.ステムやカップについては,数値解析を用いた研究成果が多 数報告されている (Bougherara, et al, 2007)(Dopico-González, et al,2010) (Hedia, et al, 2005) ) Okazaki, Kurashiki, Hanaki, Mukoyama, Li, Sugano, Uemura and Bandoh, Transactions of the JSME (in Japanese), Vol.81, No.826 (2015) (a) x-y plane (b) x-z plane -isotropic), the cortical bone restrained deformation of the flange.
