Early weight-bearing of patients with ankle fractures is associated with good outcomes. There are a number of potential advantages to early mobilisation including reduced hospital stay and earlier return to work and regular daily activities. However, many surgeons have not incorporated this into their routine ankle fracture protocol, particularly for patients managed operatively; potentially due to concerns regarding loss of reduction. We hypothesised that ankle fractures managed fully weight-bearing would have good outcomes and a low rate of loss of reduction. All ankle fractures presenting to our department over a 15-month period were studied prospectively. Patients were instructed to mobilise fully weight-bearing as able, either immediately postoperatively (for those fractures considered unstable that underwent operative intervention), or at the first fracture clinic review (if stable and managed conservatively). Only patients with syndesmotic injuries and those with neuropathy or psychiatric illness were excluded. The effectiveness of this management protocol was assessed by clinical and radiographic review following fracture union. 847 patients were included, of whom 25% were over the age of 65. 33% of fractures were unstable and therefore managed operatively, 66% were stable and therefore managed in casts or with functional bracing. In every case the radiographs showed maintenance of anatomical mortise and fracture reduction at the time of union, good patient reported outcomes were also recorded. Early weight-bearing of patients with ankle fractures, whether managed conservatively or operatively, results in very low rates of loss of reduction and should be considered routine management for the majority of patients

Background. Tightrope fixation has been suggested as an alternative to screw stabilisation for distal tibiofibular joint diastasis that provides stability but avoids the problems of rigid screws across the joint. Recent case series (of 6 and 16 patients) have however, reported soft tissue problems and infections in 19–33% of patients. This study aims to review treatment and complications of distal tibiofibular diastasis fixation in our unit with the use of Tightrope or diastasis screws. Methods. Retrospective review of all patients undergoing primary ankle fixation between May 2008 and October 2009. Exclusions included revision procedures, or ankle fixation prior to the current fracture. Those undergoing Tightrope or diastasis screw fixation were studied for any complications or further procedures. Clinical records and XRAYs were reviewed, family practitioners of the patients were contacted and any consultations for ankle related problems noted. Results. 187 primary ankle fixation procedures were performed. 35 ankles required stabilisation of the distal tibiofibular joint. In 12, this was achieved using the Tightrope and in 23, syndesmotic screws were used. There was no difference in the adequacy of reduction in the two groups. Of those stabilised with a Tightrope, 6 were Maisonneuve injuries, 5 Weber C and 1 Weber B. 1 was lost to followup. Of the remaining 11, none had complications attributable to the method of fixation documented in hospital or family practitioner records. One had a small stitch abscess that settled on removal of the suture material. None underwent subsequent procedures. Of 23 stabilised with screws, 4 were Weber B, 14 Weber C, 4 Maisonneuve and 1 syndesmotic injury associated with an isolated posterior malleolus fracture. In this group of patients with primary ankle fixation involving a diastasis screw there was 1 deep infection requiring removal of metalwork, 1 superficial wound infection after syndesmotic screw removal and 1 wound breakdown after syndesmotic screw removal. A patient developed superficial peroneal nerve palsy at operation and 1 syndesmotic fixation failed and underwent revision surgery. This patient subsequently developed infection and had revision to a hindfoot nail. 19 patients underwent screw removal. The 23 patients underwent 45 procedures (mean 1.96 procedures per patient). Conclusion. In a consecutive series of 187 ankle procedures, 12 had the distal tibiofibular joint stabilised with a Tightrope with no noted complications attributable to the implant and no additional procedures. 23 patients underwent diastasis screw fixation with 19 screw removal procedures and 5 complications of various severity, 2 of which were attributable to screw removal. Tightrope fixation has provided stable fixation of the injured syndesmosis in our unit and we have not to date encountered complications previously described in the literature

Aims

Malreduction of the syndesmosis has been reported in up to 52% of patients after fixation of ankle fractures. Multiple radiological parameters are used to define malreduction; there has been limited investigation of the accuracy of these measurements in differentiating malreduction from inherent anatomical asymmetry. The purpose of this study was to identify the prevalence of positive malreduction standards within the syndesmosis of native, uninjured ankles.
