Aims. This is a prospective randomised study which compares the radiological and functional outcomes of ring and rail fixators in patients with an infected gap (> 3 cm) nonunion of the tibia. Patients and Methods. Between May 2008 and February 2013, 70 patients were treated at our Institute for a posttraumatic osseocutaneous defect of the tibia measuring at least 3 cm. These were randomised into two groups of 35 patients using the lottery method. Group I patients were treated with a ring fixator and group II patients with a rail fixator. The mean age was 33.2 years (18 to 64) in group I and 29.3 years (18 to 65) in group II. The mean bone gap was 5.84 cm in group I and 5.78 cm in group II. The mean followup was 33.8 months in group I and 32.6 months in group II. Bone and functional results were assessed using the classification of the Association for the Study and Application of the Method of Ilizarov (ASAMI). Functional results were also assessed at six months using the short musculoskeletal functional assessment (SMFA) score. Results. The bone result was excellent, good, fair and poor in 21, 12, 0 and 2 in group I; and 14, 15, 3, and 3 in group II, respectively. The functional results were excellent, good, fair, poor and failure in 16, 17, 1, 0 and 1 in group I; and 22, 10, 0, 3 and 0 in group II, respectively. Both fixator systems achieved comparable rates of union and functional outcomes. The rate of deep pintract infection was significantly higher in the rail fixator group but patients found it more comfortable. Conclusion. We recommend the use of a ring fixator in patients with a bone gap of more than 6 cm. Patients with a bone gap up to 6 cm can be managed with either a ring or rail fixator.

Aims

In this randomized study, we aimed to compare quality of regenerate in monolateral versus circular frame fixation in 30 patients with infected nonunion of tibia.

We retrospectively reviewed 60 fractures of the tibial plafond treated by either an ankle-sparing diaphyseal-epiphyseal technique using the Ilizarov ring fixator or by an ankle-spanning technique using a monolateral articulated external fixator. The Ilizarov ring fixator was applied in 24 fractures and the monolateral articulated transarticular external fixator in 20. Both techniques were combined with limited open reduction and internal fixation of the articular surface if necessary. Between three and nine years after the injury, all patients returned for clinical and radiological assessment and evaluation of ankle function using the modified Mazur score. There were no significant differences between the two groups in terms of age, gender, mechanism of injury, type of fracture or length of follow-up. The mean functional ankle score was 86 points for the Ilizarov group and 82 points for the articulated fixator group. The difference was not significant (p = 0.07). There were no significant differences between the groups with regard to the radiographic score and late complications. Patients treated with the Ilizarov ring fixator had significantly better ankle and subtalar movement. We conclude that both techniques of external fixation are satisfactory methods of treatment for fractures of the tibial plafond, but that the total arc of movement of the joint is preserved better without bridging the ankle

Introduction. Anatomical reduction of articular fragments in tibial plateau fractures often leads to a void and there is a need to fill dead space and support the articular fragment. MIIG X3 is marketed as high strength injectable graft, which resorbs and remodels fast. Efficacy and complications related to the use of this bone graft substitute were evaluated in this study. Methods. Between January 2012 and December 2016 we injected calcium sulphate (MIIGX3) in 50 out of 126 consecutive complete articular (AO type C3) tibial plateau fractures that were stabilised with Ilizarov ring fixator. Postoperative CT scans after weight bearing and sequential radiographs were evaluated for union, graft resorption and subsidence. IOWA functional outcome score and complications were recorded. Results. The median age was 52 (Range 17–87) years. Post-operative CT scans showed leak of the graft into the joint in 11 patients and around the proximal tibiofibular joint in 2 patients but this disappeared spontaneously in all patients. Average time for graft resorption was 3.1 months. Union occurred in all patients. Minor subsidence was noted in almost half of these patients. There was no significant difference in IOWA knee score between those with or without MIIGX3 at final follow up. (p value > 0.05). Conclusion. MIIGX3 is effective as a void filler providing articular support, eradicating dead space and potentially reducing the risk of infection. Leak in the joint or soft tissue resorbed spontaneously in all cases without complications or need for surgical removal. Its use may also be associated with lack of significant late subsidence

To analyse the management of open paediatric tibial fractures treated at a children's Major Trauma Centre (MTC), comparing fixation methods, union and complications. We retrospectively identified all patients admitted to RMCH with an open tibia fracture between 2008 – 2016. Demographics, mechanism, inpatient stay and follow-up management were reviewed. There were a total of 44 patients, with an average age = 10 years (3–15). 93% of cases were caused by road traffic accidents, commonly pedestrian versus car. Older children were more likely to sustain higher grade injuries, requiring increased length of stay. 35 patients had primary / delayed wound closure, 1 patient required fasciotomies and 4/44 needed skin grafts and/or flap. 7 patients were treated in plaster, 9 by elastic nailing, 15 had mono-lateral fixators and 12 with circular frame. The average number of surgeries = 3 (1–7) with older children having increased risk of revision surgery. Monolateral fixators were the most common primary fixation method (n=15), however 60% required revision to ring fixator due to displacement or delayed union. The main risk factor for displacement was inadequate fracture reduction in theatre, as well as those fracture patterns involving butterfly fragments. Union (defined as RUST score = 3 on >3 cortices) was achieved in all patients (ave 6 months). Delayed union was associated with higher grade injuries, those treated with elastic nails demonstrated the longest union time (ave 7.3 months). 21/44 (47.7%) patients had complications, with pin site infection being the most commonly seen. 18% patients suffered a major complications needing further surgery. Various fixation methods can be successfully used to treat these fractures. They demonstrate a high complication rate and often require multiple surgeries, with union taking an average of 6 months. Mono-lateral fixators demonstrate a high revision rate, particularly if the fracture is not well reduced

Aims

To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures.

Aims

The aims of this study were to establish whether composite fixation (rail-plate) decreases fixator time and related problems in the management of patients with infected nonunion of tibia with a segmental defect, without compromising the anatomical and functional outcomes achieved using the classical Ilizarov technique. We also wished to study the acceptability of this technique using patient-based objective criteria.

The aim of this study was to report the incidence of arthrofibrosis of the knee and identify risk factors for its development following a fracture of the tibial plateau. We carried out a retrospective review of 186 patients (114 male, 72 female) with a fracture of the tibial plateau who underwent open reduction and internal fixation. Their mean age was 46.4 years (19 to 83) and the mean follow-up was16.0 months (6 to 80).

A total of 27 patients (14.5%) developed arthrofibrosis requiring a further intervention. Using multivariate regression analysis, the use of a provisional external fixator (odds ratio (OR) 4.63, 95% confidence interval (CI) 1.26 to 17.7, p = 0.021) was significantly associated with the development of arthrofibrosis. Similarly, the use of a continuous passive movement (CPM) machine was associated with significantly less development of arthrofibrosis (OR = 0.32, 95% CI 0.11 to 0.83, p = 0.024). The effect of time in an external fixator was found to be significant, with each extra day of external fixation increasing the odds of requiring manipulation under anaesthesia (MUA) or quadricepsplasty by 10% (OR = 1.10, p = 0.030). High-energy fracture, surgical approach, infection and use of tobacco were not associated with the development of arthrofibrosis. Patients with a successful MUA had significantly less time to MUA (mean 2.9 months; sd 1.25) than those with an unsuccessful MUA (mean 4.86 months; sd 2.61, p = 0.014). For those with limited movement, therefore, performing an MUA within three months of the injury may result in a better range of movement.

Based our results, CPM following operative fixation for a fracture of the tibial plateau may reduce the risk of the development of arthrofibrosis, particularly in patients who also undergo prolonged provisional external fixation.

We undertook a retrospective study of 50 consecutive patients (41 male, 9 female) with an infected nonunion and bone defect of the femoral shaft who had been treated by radical debridement and distraction osteogenesis. Their mean age was 29.9 years (9 to 58) and they had a mean of 3.8 (2 to 19) previous operations. They were followed for a mean of 5.9 years (2.0 to 19.0). The mean duration of the distraction osteogenesis was 24.5 months (2 to 39). Pin-track infection was observed in all patients. The range of knee movement was reduced and there was a mean residual leg-length discrepancy of 1.9 cm (0 to 8) after treatment. One patient required hip disarticulation to manage intractable sepsis. In all, 13 patients had persistant pain. Bony union was achieved in 49 patients at a mean of 20.7 months (12 to 35).

Although distraction osteogenesis is commonly used for the treatment of infected femoral nonunion with bone defects, it is associated with a high rate of complications.

We have carried out a retrospective review of 20 patients with segmental fractures of the tibia who had been treated by circular external fixation. We describe the heterogeneity of these fractures, their association with multiple injuries and the need for multilevel stability with the least compromise of the biology of the fracture segments. The assessment of outcome included union, complications, the measurement of the functional IOWA knee and ankle scores and the general health status (Short-form 36).

The mean time to union was 21.7 weeks (12.8 to 31), with no difference being observed between proximal and distal levels of fracture. Complications were encountered in four patients. Two had nonunion at the distal level, one a wire-related infection which required further surgery and another shortening of 15 mm with 8° of valgus which was clinically insignificant. The functional scores for the knee and ankle were good to excellent, but the physical component score of the short-form 36 was lower than the population norm. This may be explained by the presence of multiple injuries affecting the overall score.
