Purpose of this study was to compare bioactive glass and autogenous bone as a bone substitute material in tibial plateau fractures. We designed a prospective, randomized study consisting of 25 consecutive operatively treated patients with depressed unilateral tibial comminuted plateau fracture (AO classification 41 B2 and B3).14 patients (7 females, 7 males, mean age 57 years, range 25-82) were randomized in the bioglass group (BG) and 11 patients (6 females, 5 males, mean age 50 years, range 31-82) served as autogenous bone control group (AB). Clinical examination of the patients was performed at 3 and 12 months, patients' subjective and functional results were evaluated at 12 months. Radiological analysis was performed preoperatively, immediately postoperatively and at 3 and 12 months. The postoperative redepression for both studied groups was 1 mm until 3 months and remained unchanged at 12 months. No differences were identified in the subjective evaluation, functional tests and clinical examination between the two groups during 1 year follow-up. We conclude that bioactive glass granules can be clinically used as filler material instead of autogenous bone in the lateral tibial plateau compression fractures.

A fracture of the posterior malleolus was involved in every fourth tibial diaphyseal fracture. The fractures of the posterior malleolus were always detected in preoperative plain films and should be suspected, especially in cases of low-energy spiral distal tibial diaphyseal fractures. We recommend additional plain films to be taken at the ankle region to better visualize these fractures.
