Open reduction and internal fixation of the fractures was performed with two 1 cm minimal incisions over the scaphoid and trapezoid using a cannulated headless compression screw (double-threaded screw; MEIRA Corporation, Nagoya, Japan) for each fracture (Figure 3).
X-ray films at the 5-month follow-up visit. The fracture line was still visible in the scaphoid, but most part of the fracture site was united.
