摘要
背景:目前青少年膝关节不稳定型剥脱性骨软骨炎治疗方法不尽相同,效果不甚理想。目的:试验应用可吸收棒治疗青少年膝关节不稳定型剥脱性骨软骨炎,经至少2年的随访,用Lysholm,IKDC,Hughston评分和影像学检查评估固定后临床功能恢复情况及骨折的愈合情况。方法:膝关节不稳定型剥脱性骨软骨炎患者18例,在关节镜下确诊精确定位,小切口切开,用生物可吸收棒固定治疗。平均随访2.7年,用Lysholm,IKDC,Hughston评分评估患肢固定后功能的恢复,X射线平片观察固定后骨折的愈合情况。结果与结论:1固定后6个月:Lysholm、IKDC评分较术前明显改善,并且一直持续到最后一次随访时,Hughston评分15例患者优,2例患者良,1例患者结果差。2X射线片显示:17例骨性愈合,愈合率达到94%,平均愈合时间为2.9个月。3结果说明,应用可吸收棒固定治疗可促进青少年不稳定型剥脱性骨软骨炎的骨性愈合。
BACKGROUND： At present, there are different strategies for treating unsteable osteochondritis dissecans of the knee joint in adolescents, but their therapeutic effects are not ideal. OBJECTIVE： To assess the therapeutic effect of bioabsorbable pin fixation on functional recovery and fracture healing in juvenile unstable osteochondritis dissecans through Lysholm, IKDC, Hughston scoring and imaging examination. METHODS： Eighteen patients with unstable osteochondritis dissecans were enrolled. Under arthroscopy, a small incision was localized and cut followed by bioabsorbable pin fixation. The average follow-up period was 2.7 years. Functional recovery of the affected limbs after fixation was assessed by using Lysholm, IKDC and Hughston scoring. X-ray examination was used to observe fracture healing. RESULTS AND CONCLUSION： At 6 months after fixation, the Lysholm and IKDC scores were improved significantly as compared with those before operation and maintained till the last following up. There were 15 patients scored as excellent, 2 as good and 1 as poor. X-ray films also showed that there were 17 cases of fracture healing（94% healing rate）. The average fracture healing time was 2.9 months. These findings indicate that the bioabsorbable pins can improve the bone healing in juvenile unstable osteochondritis dissecans.
