Comparative Study
Deltoid ligament integrity in lateral malleolar fractures: a comparative analysis of arthroscopic and radiographic assessments.
Foot and ankle surgeons often rely on the medial clear space to evaluate competency of the deep deltoid ligament when evaluating ankle fractures. This investigation assesses the integrity of the deep deltoid ligament after lateral malleolar fracture by using direct arthroscopic visualization and medial clear-space separation on plain film radiographs. The objectives of this study were to test the reliability of medial clear-space separation and the Lauge-Hansen classification scheme in predicting deep deltoid rupture in displaced lateral malleolar fractures. ⋯ Three fractures were not classifiable; another 3 fractures showed deltoid ligament integrity opposite the expected finding. The results indicate that, in isolated displaced fractures of the lateral malleolus, radiographic widening of the medial clear space is not a reliable indicator for deep deltoid rupture. Some fractures considered stable by the Lauge-Hansen classification may require careful scrutiny to rule out deep deltoid injury.

Twenty-three patients with 25 intraarticular fractures of the calcaneus were treated during a 7-year period with minimally invasive open reduction of the posterior facet, external ring fixation, and early weightbearing. Skeletal traction and a minimally invasive lateral approach were used to elevate the posterior facet. Percutaneous wires, which were secured to an external ring fixator, were used to stabilize the reduction. ⋯ The average length of the treatment period with the fixator was 6.6 weeks (range, 5 to 9 weeks). The range of follow-up was 2 to 7 years. The results with this technique indicate that it is a viable alternative to traditional methods of open reduction and internal fixation for the management of intraarticular fractures of the calcaneus.
