鏡視下腱板修復術はsuture bridge（SB）法へと進化してきた．われわれもSB法を導入し腱板の整復を意識した修復を行っている．今回，滑液包側にknotがでないSB法群（－群），knotがでるSB法群（＋群）の臨床成績，腱板修復状態，術後肩峰下骨形態を検討したので報告する．－群29肩，＋群20肩を対象とした．両群間で性差，年齢，断裂形態に有意差はなかった．臨床成績を術前，術後1年時のJOA scoreで，腱板修復状態を術後1年時MRIで評価した．肩峰下骨形態は術後1年時CTで，一部が浸食されたimpingement type，腱板の形に適合したcongruity type，変化がないnormal typeに分類し評価した．臨床成績は－群，術前平均60.1点が術後平均92.9点へ，＋群，術前平均63.1点が術後平均94.4点へと有意に改善した．腱板修復状態は再断裂率が－群，21%，+群25%であった．肩峰下骨形態は－群でcongruity type，＋群でimpingement type，congruity typeの割合が高かった．臨床成績，腱板修復状態は概ね良好であった．肩峰下骨形態に関してはknotの有無，糸の質が影響していた．

© 2014 IPEM.Stress shielding-related proximal femoral bone loss after total hip arthroplasty occurs because of the different stiffness of metallic alloy stems and host bone. To overcome this, we fabricated a low-modulus cementless hip stem from β-type Ti-33.6Nb-4Sn alloy (TNS). Then we evaluated its stiffness, stress shielding, and initial stability compared with a similar Ti-6Al-4V alloy stem. Stiffness was determined by axial compression and cantilever-bending tests. Thirteen triaxial strain gages measured cortical strain. Stress shielding was defined as the percentage of intact strain after stem insertion. To evaluate initial stability, displacement transducers measured axial relative displacement and rotation. Intact and implanted femurs underwent single-leg-stance loading. Axial stiffness was 56% lower in the TNS stem than in the Ti-6Al-4V stem, and bending stiffness of the TNS stem decreased gradually from the proximal region to the distal region, being ≤53% that of the Ti-6Al-4V stem, indicating gradation of Young's modulus. The TNS stem decreased stress shielding in the proximal calcar region (A1: 83%, B1: 85% relative to intact cortical strain) without affecting the proximal lateral region (B3: 53%). The initial stabilities of the stems were comparable. These findings indicate that the TNS stem with gradation of Young's modulus minimizes proximal femoral bone loss and biological fixation, improving long-term stability.

This research investigates the stress distribution of the three types of implanted femurs using the finite element method analysis. The comparisons of the stress distribution between the implanted femursand the healthy femur were performed and the characteristics in the stress shielding of each casewere clarified. Since the load is transferred on the contact surface between the implant and the inner surface of the femur in the case of the total hip arthroplasty, the stress in the intertrochanteric zone (Gruen zone 7) become very small, and the phenomenon of the stress shielding is confirmed obviously. The stress distributions of the femurs afterthe resurfacing hiparthroplasty and the thrust plate prosthesis are about the same with that of the healthy femur, so, the possibility of the stress shielding is considered lower compared with the femur after the total hip arthroplasty. However, considering the stress concentration thatwill increase the risk of femoral fracture caused by the screws for the fixation of the implant in the thrust plate prosthesis, the resurfacing hiparthroplastymay beconcluded as the best method among these three types of implants to avoid stress shielding. © (2014)Trans Tech Publications,Switzerland.
