Fifth metatarsal fractures, otherwise known as "Jones" fractures, occur commonly in athletes and nonathletes alike. While recent occurrence in the popular elite athlete has increased public knowledge and interest in the fracture, this injury is common at all levels of sport. This review will focus on all three types of Jones fractures. The current standard for treatment is operative intervention with intramedullary screw fixation. Athletes typically report an acute episode of lateral foot pain, described as an ache. Radiographic imaging with multiple views of the weightbearing injured foot are needed to confirm diagnosis. If these images are inconclusive, further magnetic resonance imaging (MRI) or computed tomography (CT) is used. Nonoperative treatment is not commonly used as the sole treatment, except when following reinjury of a stable screw fixation. While screw selection is still controversial, operative treatment with intramedullary screw fixation is the standard approach. Technical tips on screw displacement are provided for Torg (types I, II, III) fractures, cavovarus foot fractures, recurrent fractures, revision surgery, occult fractures/high-grade stress reactions, and Jones' variants. Excellent clinical outcomes can be expected in 80% to 100% of patients when using the intramedullary screw fixation to "fit and fill" the medullary canal with threads across the fracture site. Most studies show the timing for return to sports with optimal healing to be seven to twelve weeks after fixation.

目的:第五跖骨骨折,也称为“琼斯”骨折,在运动员和非运动员中都很常见。虽然最近在受欢迎的精英运动员中发生的这种骨折增加了公众对这种骨折的认识和兴趣,但这种损伤在所有运动水平都很常见。这篇综述将重点介绍三种琼斯骨折。目前的治疗标准是采用髓内螺钉固定的手术干预。运动员通常会出现急性外足疼痛,表现为酸痛。需要对负重受伤的足部进行多角度的放射影像学检查以确诊。如果这些图像不确定,则进一步使用磁共振成像(MRI)或计算机断层扫描(CT)。非手术治疗通常不作为唯一治疗方法,除非在稳定的螺钉固定后再次受伤。虽然螺钉选择仍存在争议,但髓内螺钉固定的手术治疗是标准方法。为 Torg(I 型、II 型、III 型)骨折、高弓足骨折、复发性骨折、翻修手术、隐匿性骨折/高级别应力反应和琼斯变体提供了关于螺钉移位的技术提示。当使用髓内螺钉固定术“贴合和填充”髓腔,使螺纹穿过骨折部位时,80%至 100%的患者可以预期获得良好的临床效果。大多数研究表明,在固定术后七到十二周,运动员可以进行最佳愈合的重返运动。
