Range of motion, pain, consolidation and complications were evaluated for nine patients who underwent four-corner arthrodesis using the Quad Memory Staple (QMS) at a mean follow-up of 44 months. The mean pre-operative range of motion was 50 degrees extension, 62 degrees flexion, 9 degrees radial deviation and 24 degrees ulnar deviation. The postoperative range of motion was similar to previous studies at 32 degrees extension, 31 degrees flexion, 15 degrees radial deviation and 20 degrees ulnar deviation. The grip strength was 28 kg pre-operatively and 26 kg postoperatively. The mean pain score improved from 41 to 23 and the Disabilities of Arm, Shoulder, and Hand (DASH) score from 24 to 20. Non-union, haematoma and wound infection were not seen and eventually all four-corner fusions were consolidated. The main advantages of the QMS are its compressive property and the simple fixation technique. It gives good stability, enables early rehabilitation and avoids the risks of pin fixation methods.
对9例行四角关节融合术并使用四边形记忆钉（QMS）的患者进行了平均44个月的随访，评估了其活动范围、疼痛情况、融合情况及并发症。术前平均活动范围为伸展50度、屈曲62度、桡偏9度和尺偏24度。术后活动范围与先前研究相似，分别为伸展32度、屈曲31度、桡偏15度和尺偏20度。术前握力为28千克，术后为26千克。平均疼痛评分从41分改善至23分，上肢、肩部和手部功能障碍（DASH）评分从24分降至20分。未发现骨不连、血肿及伤口感染情况，最终所有四角融合均实现了愈合。QMS的主要优点在于其压缩性能和简单的固定技术。它具有良好的稳定性，可实现早期康复，并避免了克氏针固定方法的风险。
