A 34-year-old male came to our hospital for 4 days due to limited extension of his left ring finger after playing basketball. The affected finger was temporarily fixed by splint. X-ray examination was performed to confirm the diagnosis of bony mallet finger (Figures 2A,B). The next day, the patient was treated with the new technique under fluoroscopy (Figures 2C,D). Postoperative X-ray examination was performed (Figures 2E,F). After discharge, the patient was informed to review the X-ray at the outpatient clinic every 2 weeks. X-ray examination 6 weeks later showed that the fracture had healed and the K-wires were removed (Figures 3A,B). Then the patient was informed to review every 4 weeks. The recovery of finger function was evaluated at the last follow-up (Table 1 Patient No. 4, Figures 3C-F).
