    Comparison of computed tomography, traction, and inverted grayscale radiographs for understanding pilon fracture morphology
    (Sage Publications Inc, 2021-10-12) Eken, Gökay; Mısır, Abdulhamit; EKEN, GÖKAY; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Anabilim Dalı; 0000-0001-9447-4749; ABE-9918-2021
    Background: There have been no studies evaluating the usefulness of grayscale radiographs in extremity fractures. We aimed to compare the ability and reliability of traction radiographs vs traction grayscale inversion radiographs to detect fracture fragment and comminution zones in comminuted tibia pilon fractures. Methods: Plain radiographs and grayscale inversion images of 60 patients with Orthopaedic Trauma Association/AO Foundation type C3 fracture were evaluated by 20 observers (15 orthopedic surgeons and 5 radiologists) after traction had been applied. The anterolateral, posterolateral, and medial malleolar fragments, as well as the lateral, central, and medial column comminution zones, were identified by all physicians. Computed tomography scan images were used as the "gold standard" against which plain radiographs and grayscale inversion image interpretation were measured. Intra- and interobserver reliability and correct identification of fracture fragments and comminution zones were evaluated. Results: The interobserver reliability for 3 of the fracture fragments and comminution zones on the traction plain radiographs was moderate, whereas it was substantial on traction grayscale inversion radiographs. The lateral comminution zones (P = .001) and presence or absence of posterolateral fragments (P < .001) were significantly better identified in grayscale inversion radiographs compared to standard radiographs. Conclusion: After traction was applied, we found grayscale inversion radiographs are superior to plain radiographs in the identification of posterolateral fragment and lateral zone of comminution in comminuted intraarticular pilon fractures.

    Less malunion and shorter bone union time with titanium elastic nail treatment for isolated femoral shaft fractures in three- to six-year-old children

    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.
