We report the long-term results with ten patients with simple bone cysts with special retrospective reference to the radiographic evidence of healing after hole drilling. Cortical thickening was initially observed within 3 months, and minimal new bone formation around Kirschner wires left in situ was observed within 4 months. New bone formation gradually progressed from the cyst wall and around the wire. Consolidation of a cyst cavity was uniformly observed 6-7 months after drilling. In several patients residual cysts were seen between the wire and cortical shell. In younger patients, a cystic cavity reappeared after extraction of the wire, although complete radiographic healing had been observed. These findings suggest that a Kirschner wire plays an important role in preventing relapse of simple bone cysts after hole drilling.
我们报告了10例单纯性骨囊肿患者的长期结果，并特别回顾性地参考了钻孔后愈合的影像学证据。皮质增厚最初在3个月内观察到，4个月内在原位留置的克氏针周围观察到少量新骨形成。新骨形成从囊肿壁和针周围逐渐进展。钻孔后6-7个月均观察到囊肿腔的巩固。在几名患者中，在针和皮质壳之间可见残留囊肿。在年轻患者中，尽管观察到完全的影像学愈合，但在拔除针后囊肿腔再次出现。这些发现表明，克氏针在预防钻孔后单纯性骨囊肿复发中起重要作用。
