In the present report, a new radiographic classification for distal shaft fractures of the fifth metatarsal is presented. The classification system is based on a review of 79 spiral oblique fractures of the distal shaft of the fifth metatarsal. The sample was grouped into "grades" of deformity according to the configuration of the fracture and the amount of displacement observed for each injury. Four distinct fracture configurations emerged as a result of our radiographic analysis, and these were categorized as grades I, IIA, IIB, and III. Grade II fractures were most prevalent and accounted for 49% of the cases reviewed. Grade I and III fractures accounted for 29% and 22% of the distal fifth metatarsal fractures, respectively. To our knowledge, a classification system for fractures of the distal shaft of the fifth metatarsal has not been previously reported. The radiographic classification that we have proposed is intended to aid surgeons treating and discussing fractures localized to the distal portion of the fifth metatarsal.
在本报告中，提出了一种针对第五跖骨远端骨干骨折的新的影像学分类方法。该分类系统基于对79例第五跖骨远端骨干螺旋斜形骨折的回顾。根据骨折的形态以及每种损伤所观察到的移位程度，将样本分为不同的“畸形等级”。通过影像学分析，出现了四种不同的骨折形态，分别归类为I级、IIA级、IIB级和III级。II级骨折最为常见，占所回顾病例的49%。I级和III级骨折分别占第五跖骨远端骨折的29%和22%。据我们所知，此前尚未有针对第五跖骨远端骨干骨折的分类系统报道。我们所提出的影像学分类旨在帮助外科医生治疗和讨论局限于第五跖骨远端的骨折。
