Failure rate of each fracture type. Cases with cut-out or telescoping of the internal fixator of more than 10 mm were defined as the F-group. The failure rate was the percentage of cases in the F-group. Cases without cut-out or telescoping of the internal fixator of more than 10 mm were defined as the N-group. The failure rate is 6.3 % in type 2–3, 8.3 % in type 2–3, 9.8 % in type 3–4, and 14.3 % in type 2–3–4
