结果未发生与生物材料不耐受相关的生物学或临床并发症。对接骨材料的耐受性一般，因为我们观察到1例感染和12例与斯台普斯相关的疼痛，其中8例患者需要取出材料。骨愈合率为98.5%。80.5%的患者最终矫正为外翻3度至6度。术后X线片与骨愈合片之间存在矫正角度丢失。与持续矫正相关的因素有：楔形块未骨折、胫骨外侧皮质完整、双斯台普斯接骨术。96%的患者骨结合良好且快速。我们发现两个完整的透亮线，在最后的后续行动，但与变量的吸收取决于形状的骨substitute.ConclusionUse的陶瓷楔形填充胫骨内侧开放楔形截骨术的差距是一个可靠的可重复的技术，提供纠正没有形成一个排列不良的骨痂。98.5%的病例在约3个月时实现骨愈合。96%的患者骨结合良好。当替代物以颗粒形式植入松质骨区时，吸收是完全和快速的，而当作为块状楔形物植入时，吸收是部分和缓慢的。
ResultsThere were no biological or clinical complications related to biomaterial intolerance. Tolerance to the osteosynthesis material was mediocre since we observed one infection and 12 cases of pain related to the staples which required material removal in 8 patients. Bone healing was achieved in 98.5%. Final correction was between 3 degrees and 6 degrees valgus in 80.5%. There was a loss of correction angle between the postoperative film and the bone healing film. Factors related to sustained correction were: non-fractured wedge, intact lateral tibial cortical, osteosynthesis with two staples. Osteointegration was good and rapid in 96%. We found two complete lucent lines at last follow-up but with variable resorption depending on the shape of the bone substitute.ConclusionUse of a ceramic wedge to fill high tibial medial open-wedge osteotomy gap is a reliable reproducible technique providing correction without formation of a malalignment callus. Bone healing is achieved in 98.5% of the cases at about three months. Osteointegration is good in 96%. Resorption is complete and rapid when the substitute is implanted in granular form in a cancellous zone and is partial and slow when implanted as a massive wedge.
