| Abstract: | 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. |
