摘要

简介及重要性：钩骨骨折是一种非常罕见且常被遗漏的损伤。这些骨折可发生在第4或第5掌骨骨折脱位，典型的机制是直接打击鱼际下隆起。根据骨折类型和移位情况，钩骨骨折可以非手术治疗，也可以手术治疗，采用经皮钢丝、钢板或无头加压螺钉。病例介绍：我们报告了一例冠状钩骨体骨折伴4mm错位伴第5 CMC关节半脱位的患者，采用两枚无头加压螺钉固定钩骨。临床讨论：我们的研究表明在钩骨钩内有放置两枚无头加压螺钉的空间，这将防止旋转并允许加压，我们认为这优于一枚无头加压螺钉。结论：如果怀疑系骨骨折，应进行CT检查。此外，两个无头加压螺钉通过单一背侧切口是冠状钩状体骨折的有效治疗选择。

Hamate body fracture treated with headless compression screws: A case report

Introduction and importance

Hamate fractures are a very rare and commonly missed injury. These fractures can occur with 4th or 5th metacarpal fracture dislocations and the typical mechanism is a direct blow over the hypothenar eminence. Depending on the fracture pattern and displacement, hamate fractures can be treated nonoperatively or operatively with percutaneous wires, plates, or headless compression screws.

Case presentation

We present a case of a patient with a coronal hamate body fracture with 4 mm of diastases with subluxation of the 5th CMC articulation treated with two headless compression screws into the hook of the Hamate.

Clinical discussion

Our study shows there is room for two headless compression screws within the hook of the hamate that will prevent rotation and allow compression that we believe is superior to one headless compression screw.

Conclusion

If there is a suspicion for a hamate fracture, a CT should be obtained. Additionally, Two headless compression screws through a single dorsal incision are an effective treatment option for a coronal hamate body fracture.
