Despite the suggestion by Virchow in 1856 that thrombosis was the result of venous stasis, endothelial dysfunction and hypercoagulability there are some fundamental questions which remain to be answered. The published studies fail to provide specific details such as cast type and anatomical location of the thrombosis, but instead focus on the incidence of VTE and which chemical thromboprophylaxis is most effective. Previous studies of VTE in trauma patients have involved small numbers of patients and have not look at the risk medium to long term risk. Most importantly they have not looked at the site of the VTE. This makes interpretation of the link between cast and VTE even more complex. We analysed 1479 consecutive trauma cast applications and the incidence of symptomatic VTE in the six months following the injury. The diagonosis, cast type and site of the VTE was recorded.Background
Methodology
Approximately 20% of patients with ankle fracture sustain syndesmosis injury. This is most common in trans-syndesmotic (type B) and supra-syndesmotic (type C) fibula fractures. Intra-operative assessment of syndesmosis integrity is important because failure to treat these injuries can result in ankle instability and pain. Our aim was to audit the documentation of intra-operative testing of syndesmosis during ankle fracture open reduction and internal fixation (ORIF). All patients who had ankle fracture ORIF between 1/1/2010 and 21/11/2011 were included. Pre-operative radiographs were reviewed and fractures were classified according to AO classification. Operation notes were reviewed for documentation of assessment of syndesmosis integrity. 153 patients, of mean age 50 years (15–93) were included. 60% (n=92) were female. In 78% of cases (n=119), an assessment of syndesmosis integrity was documented in the operation note. Of the patients with no documented syndesmosis assessment (n=35), the majority had type B fractures (n=34). One patient had a type C fracture. We have shown that 22% of patients undergoing ankle ORIF for fracture do not have documented assessment of syndesmosis integrity. We suggest that all patients who have ankle ORIF should have intra-operative assessment and documentation of syndesmosis integrity so these injuries are identified and treated accordingly.
