Introduction. Syndesmosis injuries are significant injuries and require anatomical reduction. However, stabilisation of these injuries with syndesmosis screws carries specific complications and many surgeons advocate a second operation to remove the screw. Primary Tightrope suture fixation has been shown to be an effective treatment for syndesmotic injuries and avoids the need for a second operation. Materials and Methods. A retrospective audit identified patients who were treated for syndesmosis injuries over a two year period. Theatre and clinic costs were obtained to compare the cost of syndesmosis fixation using diastasis screws with the estimated cost of primary syndesmosis fixation using a Tightrope suture. Results. 79 patients received diastasis screw fixation of syndesmosis injuries between January 2007 and January 2009. The mean number of follow up clinic appointments was 3.7 following initial surgery, and 2.2 following diastasis screw removal. Allowing for device, theatre time and clinic appointment costs, and an estimated average of 4 follow up appointments following Tightrope syndesmosis fixation, primary fixation with this device could a saving of 34 theatre slots, 68 outpatient clinic appointments, and £12,138 per year at our hospital. Discussion. Biomechanical studies have demonstrated a reduction in normal tibiotalar external rotation with the presence of a diastasis screw, and there are several published reports of complications when these screws are retained. The Tightrope suture provides reduction of the syndesmosis whilst allowing normal physiological movement at the distal tibiofibular joint and negates the need for a second operation to remove the implant. In addition there may be improvements in foot and ankle scores and a faster return to work when these devices are used compared with traditional screw fixation. Conclusion. In addition to the patient benefits, our audit suggests that there may be significant financial benefits associated with primary syndesmosis fixation with Tightrope sutures

The diagnosis of Lisfranc ligament disruption is notoriously difficult. Radiographs and MRI scans are often ambiguous therefore a stress-test examination under anaesthesia is commonly required. Two midfoot stress-tests are in current practice, namely the varus first ray stress-test and the pronation abduction test. The optimal type of stress-test is not however evaluated in the literature. We hypothesised that after the loss of the main plantar stabiliser (the Lisfranc ligament) the patient would demonstrate dorsal instability, not the classic 1. st. /2. nd. metatarsal diastasis commonly described. We therefore devised a push-up test (placement of a force under the 2. nd. metatarsal in an attempt to elevate the base away from the middle cuneiform on the lateral radiograph). We aimed to initially test our hypothesis on a cadaveric model. Twelve fresh frozen cadaveric specimens without previous foot injury were used. The 2. nd. tarsometatarsal joint was exposed and the Lisfranc ligament and dorsal capsule were incised. An image intensifier was positioned and standard anteroposterior (AP) and lateral views were obtained. Two previously reported AP stress-tests (varus first ray stress test, pronation abduction test) and the novel test under investigation (‘Lisfranc Push-Up’ test) were duly performed. Images were obtained once the investigator felt the appropriate views were achieved. All twelve of the Lisfranc Push-Up tests showed dorsal subluxation of the 2. nd. metatarsal on the middle cuneiform of greater than 2mm on the lateral radiograph. No diastasis of the 1. st. /2. nd. metatarsals was seen in any of the specimens on the AP radiograph for either of the other two stress-tests. The authors have described a novel way of demonstrating the dorsal instability associated with the ligamentous Lisfranc injury. Our results support the Lisfranc Push-Up test as a reproducible and sensitive method for assessing ligamentous Lisfranc injuries. In our cadaveric model the previously described stress-tests do not work

Introduction:. Fibular malreduction is a common and important cause of pain after surgical fixation following a syndesmosis injury, but it is unclear which components of malreduction correspond to clinical outcome. Plain radiographs have been shown to be unreliable at measuring malreduction when compared to CT scans. A number of published methods for measuring fibular position rely on finding the axis of the fibula. Elgafy demonstrated that fibular morphology varies greatly, and some studies have demonstrated difficulty finding the fibular axis. Methods:. We developed a new method of measuring the distal fibular position on CT images. We used CT studies in 16 normal subjects. Two assessors independently measured the ankle syndesmosis using the Davidovitch method, and our new protocol for fibular AP position, diastasis and fibular length. Results:. We demonstrated that after statistical analysis (Pearson Product Moment Correlation) our method showed improved inter-observer reliability (r = 0.99 and 0.95 vs 0.59 and 0.78 respectively) for diastasis and AP translation, and improved intra-observer reliability (r = 0.99 and 0.99 vs 0.91 and 0.97 respectively). We found inter and intra observer reliability of 0.80 and 0.91 respectively for fibular length, but were unable to find a novel, accurate method for measuring fibular rotation. Conclusions:. Our method is a new, simple, accurate and reproducible system for measuring the ankle syndesmosis. We believe that this method could be used to assess fibular reduction after obtaining CT images of the uninjured side for comparison

Aims

The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes.

Aims

The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome.

Ankle fractures are one of the most common bony injuries presenting to the trauma surgeon. The more severe ones result in disruption of the tibiofibular syndesmosis and hence worse outcome. The outcome depends on accurate reduction of syndesmosis. The two main options in managing these injuries are syndesmotic screws or tightrope. The aim of this study is to compare the rate of complications between these two techniques and their radiographic results. Retrospective data from 62 patients between September 2009 and March 2011 who had fixation of syndesmosis was obtained from theatre logbooks. 46 patients had syndesmotic screws inserted while 16 had tightrope. The average age was comparable in both groups (51 years v/s 41). 25 of the 46 syndesmotic screws inserted were removed. No tightropes had to be removed for any reason. 2 patients with syndesmotic screws had wound complications while 1 patient which tightrope insertion had a persistent diastasis. There were no differences in radiological outcome between the two groups with regards to reduction of syndesmosis (measured by talofibular clear space minus medial clear space) (p-value 0.283). The difference between the talocrural angles was also of no significance (p-value 0.344). Our results indicate that tightropes achieve radiologically similar reduction of syndesmosis as screws without any significant difference in complications. The need for a second operation is significantly lower with tightrope fixation

Injury to the syndesmosis occurs in approximately 10% of all patients with ankle fractures. Anatomic restoration of the syndesmosis is the only significant predictor of functional outcome. Several techniques of syndesmosis fixation are currently used such as cortical screws, bioabsorbable screws and more recently introduced suture-button fixation. No single technique has been shown to be superior to the others. The objective of this research project is to investigate whether treatment with a tightrope (suture-button fixation) gives superior results than the use of a cortical screw in the treatment of acute syndesmotic ankle injuries with regards to function, pain, satisfaction and return to normal activities. Research Ethics Committee approval was obtained. 40 patients with syndesmotic ankle injuries associated with diastasis were prospectively recruited, 20 in each group. Patients were randomized to one of the 2 groups. At 12 weeks, American Orthopaedic Foot and Ankle Society (AOFAS) scores and a computerized tomography (CT) scan of both the ankles was obtained. At 1 year, AOFAS scores and satisfaction was assessed. 32 patients have been recruited so far, 20 in the tightrope group and 12 in the cortical screw group. Mean AOFAS scores at 3 months post-op were 90.67 in the Tightrope group and 84 in the screw group. The difference was not significant (p= 0.096). CT scans revealed that the quality of syndesmosis reduction was equally good with both the techniques. Metalwork prominence was common with both the devices. Discussion and Conclusion. Both the devices achieved good reduction of the syndesmosis. Our CT scan protocol has insignificant radiation risk and allows more accurate assessment of the syndesmosis. Early clinical results do not show a significant difference in the functional outcome with the use of either device. Long-term (1 year) follow-up has been planned

Aims

The aim of this retrospective study was to compare the functional and radiological outcomes of bridge plating, screw fixation, and a combination of both methods for the treatment of Lisfranc fracture dislocations.

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration.

In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

In this retrospective study, using the prospectively collected database of the AO-Documentation Centre, we analysed the outcome of 57 malunited fractures of the ankle treated by reconstructive osteotomy. In all cases the position of the malunited fibula had been corrected, in several cases it was combined with other osteotomies and the fixation of any non-united fragments. Patients were seen on a regular basis, with a minimum follow-up of ten years. The aim of the study was to establish whether reconstruction improves ankle function and prevents the progression of arthritic changes.

Good or excellent results were obtained in 85% (41) of patients indicating that reconstructive surgery is effective in most and that the beneficial effects can last for up to 27 years after the procedure. Minor post-traumatic arthritis is not a contraindication but rather an indication for reconstructive surgery. We also found that prolonged time to reconstruction is associated negatively with outcome.
