Since June 1980, sapphire pins (monocrystalline alumina ceramic pins) have been used in 22 patients as an internal fixation device for hand and elbow problems. In our follow-up studies, good bone healing was observed in all cases except for one delayed union in a fracture of the diaphysis of the proximal phalanx. Radiographs showed no pin migration or osteolytic reaction around the pins. We therefore conclude that our device and its insertion technique can be successfully applied to intraarticular fractures and fractures in the vicinity of the joint.
自1980年6月以来，蓝宝石针（单晶氧化铝陶瓷针）已被用于22例患者，作为手部和肘部问题的内固定装置。在我们的随访研究中，除了一例近端指骨干骨折延迟愈合外，所有病例均观察到良好的骨愈合。X线片显示针周围无针移位或溶骨反应。因此，我们得出结论，我们的装置及其插入技术可以成功应用于关节内骨折和关节附近的骨折。
