  • 1

    Hamate body fractures account for less than 5% of carpal fractures and may be more common than previously reported.

  • 2

    Surgical intervention is often required for coronal hamate body fractures due to associated displacement and instability of the CMC joints.

  • 3

    Limited literature exists on coronal hamate body fractures, with most reports being case studies or small series.

  • 4

    Fracture morphology and associated injuries were analyzed in patients with coronal hamate body fractures and CMC joint instability.

  • 5

    A stepwise surgical approach was described, focusing on fracture reduction and fixation to ensure optimal clinical outcomes.
