Table 3.
Analysis of tibia callus subsidence by taking into account calluses of type 1 and type 2, amount of lengthening, and percentage of lengthening
| Amount of lengthening | |||
|---|---|---|---|
| <5 cm | 5–10 cm | >10 cm | |
| Type 1 callus | 0.97 ± 0.68 | 0.96 ± 0.5 | 2.2 ± 0.86 |
| Type 2 callus | 0.55 ± 0.25 | 1.04 ± 0.63 | 1.3 ± 0.87 |
| p value | 0.26 | 0.67 | 0.025 |
| Percentage of lengthening | |||
| <25% | 25–50% | >50% | |
| Type 1 callus | 0.71 ± 0.40 | 1.4 ± 0.77 | 2.1 ± 0.84 |
| Type 2 callus | 0.74 ± 0.41 | 1.2 ± 0.85 | 1.1 ± 0.65 |
| p value | 0.89 | 0.5 | 0.02 |
The values in the tables are mean subsidence ± standard deviation. Type 1 callus is segment with only three cortices seen at the time of fixator removal. Type 2 callus is segment with all four cortices seen at the time of fixator removal. All p values are for unpaired t test
