摘要

反肩关节置换术(RSA)用于治疗袖带撕裂性关节病患者。松动仍然是植入物失败的主要模式之一,也是导致翻修的主要并发症。过度的微动会导致关节盂松动。这项研究评估了一个实验系统的预测准确性,该系统旨在评估RSA关节盂基板微动的因素。设计了一个半析因实验来评估4个因素:中心元件类型(螺钉与销钉)、中心元件长度(13.5与23.5 mm)、前后外周螺钉类型(锁定与非锁定)和松质骨密度(10与25磅/立方英尺[pcf])。四个线性可变差分换能器(LVDT)记录了一个不锈钢圆盘围绕一个改良的关节盂球的微运动。位移被用来对各个外围螺钉位置处的微运动进行插值。平均绝对百分比误差(MAPE)用于确定系统的预测精度和误差范围。对于(9.5±0.9)%的总MAPE,每个条件的MAPE范围为6.8%至12.9%;m至20.1µ;m、 其低于先前使用光学系统的研究所报告的那些。八个条件中的一个条件具有超过150µ;m.这些发现支持使用位移传感器,特别是LVDT,作为确定刚性聚氨酯泡沫骨替代物中RSA基板微运动的精确系统。

Accuracy of an Apparatus for Measuring Glenoid Baseplate Micromotion in Reverse Shoulder Arthroplasty
Reverse shoulder arthroplasty (RSA) is used to treat patients with cuff tear arthropathy. Loosening remains one of the principal modes of implant failure and the main complication leading to revision. Excess micromotion contributes to glenoid loosening. This study assessed the predictive accuracy of an experimental system designed to assess factors contributing to RSA glenoid baseplate micromotion. A half-fractional factorial experiment was designed to assess 4 factors: central element type (screw vs. peg), central element length (13.5 vs. 23.5 mm), anterior posterior peripheral screw type (locking vs. nonlocking) and cancellous bone density (10 vs. 25 pounds per cubic foot [pcf]). Four linear variable differential transducers (LVDTs) recorded micromotion from a stainless-steel disc surrounding a modified glenosphere. The displacements were used to interpolate micromotion at each of the respective peripheral screw positions. The mean absolute percentage error (MAPE) was used to determine the predictive accuracy and error range of the system. The MAPE for each condition ranged from 6.8% to 12.9% for an overall MAPE of (9.5±0.9)%. The system had an error range of 2.7 µm to 20.1 µm, which was lower than those reported by prior studies using optical systems. One of the eight conditions had micromotion that exceeded 150 µm. These findings support the use of displacement transducers, specifically LVDTs, as an accurate system for determining RSA baseplate micromotion in rigid polyurethane foam bone surrogates.
