结论螺钉髓内固定和震波治疗都是治疗第五跖骨干骺端骨折不愈合的有效方法。
Conclusions Both intramedullary screw fixation and shock wave therapy are effective treatments for fracture nonunion in the metaphyseal-diaphyseal region of the fifth metatarsal.
背景：目前治疗第五跖骨干骺端慢性骨不愈合的金标准是髓内螺钉固定。
Background the current "gold standard" for treatment of chronic fracture nonunion in the metaphyseal-diaphyseal region of the fifth metatarsal is intramedullary screw fixation.
应特别注意近端螺钉固定，在此案例下，使用单皮质螺钉推荐用于假体干部，而双皮质螺钉用于假体之下。
Special attention should be given to the proximal screw fixation. In this case the use of uni-cortical screws is recommended around the stem of the implant and bi-cortical screws below this level.
