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.
