Using the Spider plate fixation device, limited wrist arthrodesis was performed on 30 patients over a 2-year period. Developed as an alternative to Kirschner wires and compression bone screws in limited intercarpal fusions, its rigid fixation was expected to yield better results. Five hand surgeons treated 24 men and 6 women with an average age of 45 years. Diagnosis included the following: scaphoid nonunion advanced collapse, scapholunate advanced collapse, scapholunate dissociation, midcarpal arthrosis, and Kienböck disease. The 8-hole regular Spider and 6-hole mini-Spider plates were applied dorsally, and patients were immobilized for 4 weeks. In a blinded study, data results showed no significant improvement when compared with bone screws and Kirschner wires. Preliminary results showed that the Spider plate yielded higher nonunion rates and less wrist motion.
在两年时间里，使用蜘蛛板固定装置对30例患者进行了有限腕关节融合术。该装置是作为克氏针和加压接骨螺钉在有限腕骨间融合中的替代方案而开发的，其刚性固定预期能产生更好的效果。五位手外科医生治疗了24名男性和6名女性，平均年龄为45岁。诊断包括以下几种情况：舟骨不愈合伴晚期塌陷、舟月骨晚期塌陷、舟月骨分离、腕中关节病和月骨无菌性坏死。将8孔常规蜘蛛板和6孔迷你蜘蛛板应用于背侧，患者固定4周。在一项盲法研究中，数据结果显示与接骨螺钉和克氏针相比无显著改善。初步结果表明，蜘蛛板的不愈合率更高，腕关节活动度更小。
