Abstract
Purpose
Titanium elastic nail (TEN) is a good option for femoral shaft fractures in school-age children, whereas a spica cast is favored for younger patients. We aimed to compare these treatment modalities in a group of children aged three to six years.
Methods
34 patients aged 3–6 years with an isolated closed femoral shaft fracture treated with TEN or one-leg spica cast immobilization were retrospectively assessed. Age, gender, weight, mechanism of injury, hospital stay time, bone union time, radiographic shortening, malunion, and complications were compared between the treatment groups.
Results
16 (47.1%) patients who were treated with TEN (Group T) and 18 (52.9%) patients with spica casting (Group S) were included with a mean of 51 (24–94) months follow-up. The mean age was 4.98 years and statistically similar between both groups (mean, 5.2 vs. 4.8 years; p = 0.234). The patients in Group T were heavier (mean, 19.3 vs. 17.2 kg; p < 0.001) and were more likely to have a higher-energy mechanism of injury (p = 0.006). The mean late femoral shortening of Group S patient’s was 6.5 ± 3.5 mm and significantly higher than Group T, which was 2.0 ± 2.9 (p = 0.050). However, effective late femoral shortening rates were not statistically different between groups (p = 0.347). Malunion was seen in six (33.3%) patients in Group S, whereas none of the patients in Group T had malunion at the last follow-up examination and were statistically different (p = 0.011).
Conclusion
Our study identified radiographic evidence favoring TEN over spica cast immobilization in treating preschool-age children with an isolated femoral shaft fracture in terms of malunion.
