The aim of this study is to use tibial Hounsfield unit measurements from preoperative computed tomography scans of ankle fractures to predict delayed union and nonunion. We hypothesize that patients with lower Hounsfield unit averages, an indirect measure of lower bone mineral density, in the distal tibia are more likely to develop delayed union and nonunion complications after ankle fracture surgery. Patient data from January 2010 to January 2020 were retrospectively analyzed from 2 institutions.

- Posterior malleolar fractures are part of complex ankle injuries, and this study analyzes the relationship between measurements from lateral ankle X-rays and axial CT scans for predicting fracture types.
- A multi-center analysis of 279 patients identified a strong correlation between the height of the lateral fracture and the likelihood of medial extension fractures, particularly with taller measurements.
- The findings suggest that higher lateral heights (over 24.5mm) indicate an increased probability of medial extension fractures, recommending more use of CT scans pre-surgery and consideration of specific surgical approaches for these cases.
Configuration of a posterior malleolus fracture has significant variation based on mechanism of injury and concomitant ankle injuries. Radiographs obtained during early workup of ankle trauma play a pivotal role in closed reduction, surgical planning and preoperative management. Preoperative computed tomography helps distinguish fracture pathoanatomy.

The most commonly used operative methods include indirect reduction via a percutaneous anterior approach and direct reduction via a posterolateral approach. For large posterior malleolus fractures with medial extension, direct reduction via a posteromedial approach is an alternative operative option.

SPECT/CT combines bone scan with high-resolution CT and can provide functional-anatomical images in a single stage. The purpose of this study was to assess the value of SPECT/CT in the management of OLT.
