To report the consolidation rate and the results of a series of 22 patients with metaphyseal core decompression of the distal radius and an antegrade compression screw. We present a prospective series of patients with scaphoid proximal pole nonunion in whom the presence of intraoperative bleeding was confirmed in both fragments. Patients with displacement, degenerative changes, fragmentation of the proximal pole, cavitation of the focus, loss of height, and necrosis, as well as those with carpal instability, were excluded. The patients were evaluated with X-rays and computed tomography to evaluate their consolidation; their mobility and fist strength were recorded and an analog visual scale (VAS) of pain at rest, pain in activity, subjective functional status, and DASH questionnaire were completed. Of the 23 patients, 21 accomplished union. The average follow-up was 19 months and the average final range of motion was flexion 86%, extension 85%, radial deviation 79%, ulnar deviation 84%, and grip strength 84%. The average VAS for pain at rest was 1 point, the average VAS for activity pain was 2 points, the average VAS for function was 9 points, and the average DASH score was 8. Using this simple and reliable technique, we obtained 91% union and very good functional results. Metaphyseal core decompression of the distal radius associated with an antegrade scaphoid screw is a reasonable and effective option for the treatment of proximal pole scaphoid nonunions without avascular necrosis in carefully selected patients. This is Level IV study.
报告22例采用桡骨远端干骺端髓芯减压及顺行加压螺钉治疗的骨愈合率及结果。
我们前瞻性地研究了一组舟骨近极不愈合患者,术中证实两骨折块均有出血。排除有移位、退变、近极碎裂、病灶空洞形成、高度丢失、坏死的患者,以及腕关节不稳定的患者。通过X线和计算机断层扫描评估患者的骨愈合情况;记录其活动度和握力,并完成静息痛、活动痛的视觉模拟评分(VAS)、主观功能状态评估及DASH问卷。
23例患者中,21例实现了骨愈合。平均随访19个月,最终平均活动范围为:掌屈86%,背伸85%,桡偏79%,尺偏84%,握力84%。静息痛平均VAS评分为1分,活动痛平均VAS评分为2分,功能平均VAS评分为9分,DASH平均评分为8分。
采用这种简单可靠的技术,我们获得了91%的骨愈合率和非常好的功能结果。对于精心挑选的无缺血性坏死的舟骨近极不愈合患者,桡骨远端干骺端髓芯减压联合顺行舟骨螺钉是一种合理有效的治疗选择。
这是一项IV级研究。
