Case presentation A 48-year-old male presented to the hospital with severe pain and stiffness in the left small finger (LSF) for the past three months. His LSF was crushed in a door three months ago, and the X-ray image showed no soft-tissue injuries, dislocation, or acute fracture at the time (Cover image, Figure 1). The ulnar gutter splint was used to manage his crushed LSF.
However, the patient removed it in a month because of no improvement in the pain. The patient underwent hand rehabilitation and therapy for three weeks and achieved minimal functional improvement.
