There has been a considerable evolution of screws used for internal fixation of scaphoid fractures. We discuss here, early results of a recently introduced implant Synthes 3.0 mm headless compression screw used for scaphoid fracture fixation. Twenty eight patients with scaphoid fractures (five acute and 23 nonunions) were treated with internal fixation by this non-variable pitch screw over a period of 18 months. All nonunions had pedicle vascularized bone grafting. All five patients with acute scaphoid fracture fixation had radiological healing at a mean of 8 weeks. Fifteen of 23 scaphoid fracture nonunions showed definite signs and a further seven showed probable signs of radiological healing at a mean of 8 months. One nonunion has failed to unite after surgery.
用于舟骨骨折内固定的螺钉已经历了相当大的发展。在此，我们讨论一种最近推出的用于舟骨骨折固定的植入物——Synthes 3.0毫米无头加压螺钉的早期结果。在18个月的时间里，28例舟骨骨折患者（5例急性骨折和23例骨不连）接受了这种等螺距螺钉的内固定治疗。所有骨不连患者均进行了带蒂血管化骨移植。所有5例急性舟骨骨折固定患者平均在8周时实现了放射学愈合。23例舟骨骨折骨不连患者中有15例显示出明确的愈合迹象，另有7例平均在8个月时显示出可能的放射学愈合迹象。有1例骨不连患者术后未能愈合。
