目的：反式全肩关节置换术（RTSA）后，胫骨托位置可能影响临床疗效。本研究的目的是评估的风险，基板桩在RTSA. MethodsForty 4例肩袖关节病或大规模肩袖撕裂的穿透。使用其计算机断层扫描数据，模拟了胫骨托立柱的10种插入模式。首先，在轴向平面中，将基板垂直于Friedman轴放置（Friedman放置）并平行于关节盂表面放置（关节盂放置）。其次，将这些位置分为以下几组：将胫骨托立柱放置在关节盂长轴前方2 mm处（A2组）、前方1 mm处（A1组）、长轴上（C 0组）、后方1 mm处（P1组）和后方2 mm处（P2组）。将基板桩钉位于肩胛颈内的病例定义为非穿透，并对各组的非穿透率进行评估和性别比较，并评估其与患者身高的关系。A2组的未穿透率显著较高（68.2%和70.5%）和A1组（65.9%和65.9%）与P1组（18.2%和29.5%）和P2组（9.1%和13.6%;p< 0.001）相比，男性比女性（p< 0.05）。此外，非渗透率往往是较高的患者的身高increased.ConclusionsIt建议，基板桩被放置在关节盂的长轴前方。
PurposeBaseplate positioning may affect clinical outcome after reverse total shoulder arthroplasty (RTSA). The aim of this study was to evaluate the risk of penetration of the baseplate peg in RTSA.MethodsForty-four patients with rotator cuff arthropathy or massive rotator cuff tears were included. Using their computed tomography data, ten insertion patterns of the baseplate pegs were simulated. First, in the axial plane, the baseplate was placed perpendicular to the Friedman axis (Friedman placement) and parallel to the glenoid surface (glenoid placement). Second, each of these placements were classified into the following groups: The baseplate peg was placed 2 mm anterior to the long axis of the glenoid (group A2), 1 mm anterior (group A1), on the long axis (group C0), 1 mm posterior (group P1), and 2 mm posterior (group P2). Cases in which the baseplate peg was within the scapular neck were defined as non-penetration, and the non-penetration rates among each group were evaluated and compared between sexes, and their relationship with patient height was evaluated.ResultsIn both the Friedman and glenoid placements, the non-penetration rate was significantly higher in groups A2 (68.2% and 70.5%) and A1 (65.9% and 65.9%) compared with groups P1 (18.2% and 29.5%) and P2 (9.1% and 13.6%;p< 0.001) and in males than in females (p< 0.05). Furthermore, the non-penetration rate tended to be higher as the patient’s height increased.ConclusionsIt is recommended that the baseplate peg be placed anterior to the long axis of the glenoid.
