Introduction. The various problems that are managed with circular external fixation (e.g. deformity, complex fractures) also typically require serial plain x-ray imaging. One of the challenges here is that the relatively radio-opaque components of the circular external fixator (e.g. the rings) can obscure the view of the area of interest (e.g. osteotomy site, fracture site). In this presentation we describe how the geometry of the x-ray beam affects the produced image and how we can use knowledge of this to our advantage. Whilst this can be applied to any long bone, we have focused on the tibia, given that it's the most common long bone that is treated by circular external fixation. Materials & Methods. In the first part of the presentation we describe the known attributes (geometry) of the x-ray beam and postulate what effect it would have when we x-ray a long bone that is surrounded by a circular external fixator. In the second part we demonstrate this in practice using a tibia and a 3 ring circular external fixator. Differing x-ray beam orientations are used to demonstrate both how the geometry of the beam affects the produced image and how we can use this to our advantage to better visualise part of the bone. Results. The practical part of the study confirmed the theoretical part. Conclusions. Knowledge of the beam geometry can be used to minimise the obscuring nature of the circular fixator. This technique is simple and can be easily taught to the radiographer. It is a useful adjunct for the limb reconstruction surgeon

Purpose of study. Pin tract infection is a common complication with the use of circular external fixators. HIV infection itself is frequently quoted as a relative contra-indication for the use of circular external fixators for complex trauma and limb reconstruction in HIV seropositive individuals. Methods. Between July 2008 and December 2012, 286 patients were treated with circular external fixators at our tertiary level government hospital. A retrospective review was undertaken to compare the rate and severity of pin tract sepsis in HIV seropositive and seronegative patients. Results. Two-hundred and twenty-three patients met the inclusion and exclusion criteria. Pin tract sepsis was found in 51 patients overall (22.8%). The incidences of pin tract sepsis in the seropositive group, seronegative group, and the unknown group are 22.5%, 22.8% and 23.8% respectively, and the differences were not statistically significant. The severity of pin tract sepsis in the individual groups was also similar. Conclusion. Pin tract sepsis is a common complication with the use of circular external fixators. The incidence and severity of pin tract infection is not influenced by HIV infection, and should not in itself deter from the use of circular external fixators for complex trauma and limb reconstruction in HIV seropositive individuals.

We would like to present this case series of 10 adolescent patients with displaced, closed diaphyseal tibial fractures managed using the Taylor Spatial Frame.

Management options for these injuries include non-operative treatment, antegrade nailing, flexible nailing systems, plating and external circular fixation. External circular fixation allows anatomical reduction avoiding potential complications such as growth arrest associated with antegrade nailing and retained metal work with plating. Flexible nailing system and cast immobilisation are unreliable for precise anatomical reduction. With limited evidence as to the extent of post-traumatic deformity that is acceptable, combined with the limited remodeling potential that this patient group possess, the precision of percutaneous fixation with the Taylor Spatial Frame system has clear advantages.

This is a retrospective analysis of 10 adolescent patients with a mean age of 14.5 years (range 13 to 16 years). Data collected includes fracture configuration, deformity both pre and post operatively compared to post frame removal, length of time in frame and complications. The data was gathered using the patient case notes and the Picture Archiving and Communications System. The mean time in frame was 15.5 weeks (range 11 to 22 weeks). One non-union in a cigarette smoker was successfully managed with a second Taylor Spatial Frame episode.

Our conclusion was that with careful patient selection the Taylor Spatial Frame allows successful treatment of closed tibial fractures in adolescents, avoiding complications such as growth arrest and post-traumatic deformity as well as avoiding retained metalwork.

Introduction

External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting.

Introduction. Temporary spanning fixation aims to provide bony stability whilst allowing access and resuscitation of traumatised soft-tissues. Conventional monolateral fixators are prone to half-pin morbidity in feet, variation in construct stability and limited weight-bearing potential. This study compares traditional delta-frame fixators to a circular trauma frame; a virtual tibial ring block spanned onto a fine-wire foot ring fixation. Materials and Methods. The two cohorts were compared for demographics and fracture patterns. The quality of initial reduction and the maintenance of reduction until definitive surgery was assessed by two authors and categorised into four domains. Secondary measures included fixator costs, time to definitive surgery and complications. Results. Fifty-six delta-frames and 48 circular fixators were statistically matched for demographics and fracture pattern. Good or excellent initial reduction was achieved in 51 (91%) delta-frames and 48 (100%) circular fixators (p=0.022). Loss of reduction was observed in 15 (27%) delta-frames and 3 (6%) circular fixators (p<0.001). Post-fixator dislocation occurred in five (9%) delta-frames and one (2%) circular fixator (p=0.147). Duration in spanned fixation was equivalent (11.5 and 11.6 days respectively, p=0.211). Three (5%) delta-frames and 12 (25%) circular fixators were used as definitive fixation. The mean hardware cost was £3,116 for delta-frames and £2,712 for circular fixators. Conclusions. Temporary circular fixation offers statistically superior intra-operative reduction and maintenance of reduction, facilitates weight-bearing and provides more opportunity as the definitive fixation. Circular fixation hardware proved to be less expensive and protected against further scheduled and unscheduled operations

Introduction. The vast majority of orthopaedic surgeons use C-arm fluoroscopy in the operating theatre when building a circular external fixator. In the absence of previous research in this area, we hypothesised that the surgeon who builds a circular external fixator is exposed to a greater amount of radiation purely as a result of the presence of the metallic fixator in the x-ray beam. The aim of our study therefore was to investigate how the presence of a circular external fixator affects the radiation dose to the surgeon and the surgical assistant. Materials & Methods. A simulated environment was created using a radiolucent operating table, an acrylic lower limb phantom (below knee segment), various configurations of metalic circular external fixation, and a standard size C-arm image intensifier. The variables investigated were 1. the amount of metal in the beam 2. the orientation of the beam (PA vertical vs lateral) 3. the horizonal distance of the person from the beam (surgeon vs assistant) and 4. the vertical distance of the various body parts from the beam (e.g. thyroid, groin). In terms of radiation dose, we recorded two things : 1. the dose produced by the image intensifier 2. the dose rate at standardised positions in the operating theatre. The latter was done using a solid-state survey sensor. These positions represented both where the surgeon and surgical assistant typically stand plus the heights of their various body regions relative to the operating table. Results. The effect of the presence of the circular external fixator : all frame constructs tested resulted in a statistically significant greater radiation dose both produced by the image intensifier and received by the surgical team. The effect of the beam orientation : the PA (vertical) orientation resulted in a statistically significant greater radiation dose for the surgeon than did the lateral orientation, but made no difference for the assistant. The effect of horizontal distance from the beam : unsurprisingly, the surgeon (who was closer to the beam) received a statistically significant greater radiation dose than the assistant. The effect of vertical distance from the beam : for the surgeon, the dose received was highest at the level of the phantom leg / frame, whilst for the assistant there was no statistically significant difference for any level. Conclusions. To our knowledge, this is the first study investigating the radiation dose rate to the orthopaedic surgeon when building a circular external fixator. We found that the surgeon does indeed receive a ‘double whammy’ because the image intensifier puts out a greater amount of radiation plus the metalic frame scatters more of the x-ray beam. Whilst the amounts are relatively small, we think that it's important to quantify doses that orthopaedic surgeons receive to ensure optimal radiation practices

Introduction. Knee arthrodesis is a useful limb salvage technique to maintain function in patients with complex and infected total knee arthroplasties (TKA). There are a number of commonly used external fixators, but no consensus on which of these are optimal. The aim of this study was to synthesise the current literature to guide clinical decision making and improve patient outcomes. We systematically review the literature to compare outcomes of external fixators in arthrodesis following infected TKA. Materials & Methods. A systematic review of the literature of primary research articles investigating the use of external fixators for knee arthrodesis after an infected TKA was conducted. Relevant articles were identified with a search strategy on online databases (EMBASE and Medline) and reviewed by two independent reviewers. Clinical outcome measures were independently extracted by two reviewers which included union rate, infection eradication rate, complication rate, time to fusion, and time in frame. Results. Circular frames were more likely to result in union compared to biplanar (OR 1.40 p=0.456) and monoplanar frames (OR 2.28 p=0.018). Infection recurrence was least likely in those treated by circular frames when compared to monoplanar (OR 0.12 p=0.005) and biplanar external fixators (0.41 P=0.331). Complication rates were highest in the circular fixator group, followed by the monoplanar fixator group and biplanar fixator group at 34%, 31% and 11% respectively. Conclusions. Analysis of the available literature suggests higher union and infection eradication rates with circular frames over the other two fixation methods despite a higher complication rate. There is a paucity in the literature and therefore, no firm conclusions can be drawn. Further research investigating the variations and biomechanical properties between different external fixation methods for knee arthrodesis is necessary. Further clarity in reporting and pooled data would be useful for future analysis

Introduction. Treatment of non-union in open tibial fractures Gustilo-Anderson(GA)-3A/3B fractures remains a challenging problem. Most of these can be dealt using treatment methods that requires excision of the non-union followed by bone grafting, masquelet technique, or acute shortening. Circular fixators with closed distraction or bone transport also remains a useful option. However, sometimes due to patient specific factors these cannot be used. Recently antibiotic loaded bone substitutes have been increasingly used for repairing infected non-unions. They provide local antibiotic delivery, fill dead space, and act as a bone conductive implant, which is resorted at the end of a few months. We aimed to assess the outcome of percutaneous injection of bone substitute while treating non-union of complex open tibial fractures. Materials & Methods. Three cases of clinical and radiological stiff tibial non-union requiring further intervention were identified from our major trauma open fracture database. Two GA-3B cases, treated with a circular frame developed fracture-related-infection(FRI) manifesting as local cellulitis, loosened infected wires/pins with raised blood-markers, and one case of GA-3A treated with an intramedullary nail. At the time of removal of metalwork/frame, informed consent was obtained and Cerament-G. TM. (bone-substitute with gentamicin) was percutaneously injected through a small cortical window using a bone biopsy(Jamshedi needle). All patients were allowed to weight bear as tolerated in a well-fitting air-cast boot and using crutches. They were followed up at 6 weekly intervals with clinical assessment of their symptoms and radiographs. Fracture union was assessed using serial radiographs with healing defined as filling of fracture gap, bridging callus and clinical assessment including return to full painless weight bearing. Results. Follow-up at 6 months showed all fractures had healed with no defect or gaps with evidence of new trabecular bone and significant resorption of Cerament-G. TM. at final follow-up. There was no evidence of residual infection with restoration of normal limb function. Fractures with no internal fixation showed a mild deformity that had developed during the course of the healing, presumed due to mild collapse in the absence of fixation. These were less than 10 degrees in sagittal and coronal planes and were clinically felt to be insignificant by the patients. Conclusions. Cerament-G's unique combination of high dose antibiotics and hydroxy apatite matrix provided by calcium sulphate might help provide an osteoconductive environment to allow these stiff non-unions to heal. The matrix appears to provide a scaffold-like structure that allows new bone in-growth with local release of antibiotics helping reduce deep-seated infections. The final deformation at fracture site underlines the need for fixation- and it is very unlikely that this technique will work in mobile nonunions. Whilst similar fractures may heal without the use of bone substitute injections, the speed of healing in presence of significant fracture gap suggests the use of these bone substitutes did help in our cases. Further studies with a larger cohort, including RCTs, to evaluate the effectiveness of this technique compared to other methods are needed

Introduction. Intra articular distal tibia fractures can lead to post-traumatic osteoarthritis. Joint distraction has shown promise in elective cases. However, its application in acute fractures remains unexplored. This pilot study aims to fill this knowledge gap by investigating the benefits of joint distraction in acute fractures. Materials & Methods. We undertook a restrospective cohort study comprising patients with intra-articular distal tibia and pilon fractures treated with a circular ring fixator (CRF) at a single center. Prospective data collection included radiological assessments, Patient-Reported Outcome Measures (PROM), necessity for additional procedures, and Kellgren and Lawrence grade (KL) for osteoarthritis (OA). 137 patients were included in the study, 30 in the distraction group and 107 in the non-distraction group. There was no significant difference between the groups. Results. Mean follow-up was 3.73 years. There was no significant difference between the groups in overall complications or need for further procedures. There was no significant difference in progression of KL between the groups (1.81 vs 2.0, p=0.38) mean follow up 1.90 years. PROM data was available for 44 patients (6 distraction, 38 non-distraction) with a mean follow-up of 1.71 years. There was no significant difference in EQ5D (p=0.32) and C Olerud-H Molander scores (p=0.17). Conclusions. This pilot study suggests that joint distraction is safe in the acute setting. However, the study's impact is constrained by a relatively small patient cohort and a short-term follow-up period. Future investigations should prioritise longer-term follow-ups and involve a larger patient population to more comprehensively evaluate the potential benefits of joint distraction in acute fractures

Introduction. Circular external fixators are fundamental to lower limb reconstruction, primarily in situations with a high risk of infection such as open fractures. During the Covid-19 pandemic, use of circular frames in our unit decreased, following departmental approval, due to resource management and in keeping with BOA guidelines as we opted to “consider alternative techniques for patients who require soft tissue reconstruction to avoid multiple operations”. These alternatives included the use of internal fixation (plate osteosynthesis and intramedullary nailing) as a measure to reduce the number of hospital attendances for patients and to conserve resources. This change in practice has continued in part following the pandemic with the increased use of internal fixation in cases previously deemed unsuitable for such techniques. We present our experience of this treatment strategy in the management of complex lower limb injuries, focusing on outcomes and consider the lessons learnt. Materials & Methods. Data of patients with complex lower limb injuries treated before, during and after the pandemic were collected from our in-house trauma database, theatre records and follow up clinics. The rationale for choosing other techniques over a circular frame, the type of alternative technique used, the cost of such alternatives, the need for soft tissue reconstruction, time to recovery, complications and amputation rates were compared among groups. Results. These data suggest comparable outcomes between circular frames and alternative techniques can be achieved. A notable reduction in the number of circular frames applied during the review period was observed. Furthermore, frame fixation was associated with more frequent outpatient review and the associated implications for resource management. Conclusions. Conclusion: The Covid-19 pandemic has posed great challenges to the Trauma and Orthopaedic community, forcing us to be flexible by adopting alternative treatment methods to traditional circular external fixation. These alternatives have proven feasible and potentially more cost effective, prompting their adoption in the post pandemic era. However, this change of practice is not without potential consequences and continued investigation is warranted

Introduction. The accuracy of hexapod circular external fixator deformity correction is contingent on the precision of radiographic analysis during the planning stage. The aim of this study was to compare the SMART TSF (Smith and Nephew, Memphis, Tennessee) in-suite radiographic analysis methods with the traditional manual deformity analysis methods in terms of accuracy of correction. Materials and Methods. Sawbones models were used to simulate two commonly encountered clinical scenarios. Traditional manual radiographic analysis and digital SMART TSF analysis methods were used to correct the simulated deformities. Results. The final outcomes of all six analysis methods across both simulated scenarios were satisfactory. Any differences in residual deformity between the analysis methods are unlikely to be clinically relevant. All three SMART TSF digital analyses were faster to complete than manual radiographic analyses. Conclusions. With experience and a good understanding of the software, manual radiographic analysis can be extremely accurate and remains the gold standard for deformity analysis. In-suite SMART TSF radiographic analysis is fast and accurate to within clinically relevant parameters. Surgeons can with confidence trust the SMART TSF software to provide analysis and corrections that are clinically acceptable

Introduction. Open tibial fractures are associated with an increased risk of infection. The infection rate increases with increasing severity and grade of fracture. Various management options available for fracture treatment are in turn associated with complications including infection. Circular fine-wire fixators cause minimal intra-operative soft tissue disruption and possibly have a better outcome and low complication rates. Objectives. To analyse the effectiveness of circular fine-wire fixators in managing open tibial fractures and to determine the incidence of complications, particularly infection associated with use of these fixators. Methods. A retrospective review of 34 open tibial fractures treated with circular fine-wire fixators [Ilizarov and Taylor Spatial Frame (TSF)] in a teaching hospital. Results. We treated 34 patients (n=34) with fine-wire fixators. An Ilizarov frame was used for 19 (56%) and TSF was used for 16 (44%) patients. Mean patient age was 47.1 years. Seventy four percent had high energy while 26% had low energy injury. Consequently 4 (12%) had grade I, 3 (9%) had grade II, 6(17%) had grade IIIA and 21(62%) had grade IIIB injury as per the Gustilo-Anderson Classification. Forteen percent of patients had proximal, 17% had mid-shaft, 67% had distal tibial fractures respectively. Average time to union was 28.9 weeks. Grade IIIB fractures healed in 29.6 weeks. Fifty percent of these patients were full weight bearing immediately after surgery. 17 required soft tissue coverage and only two developed skin graft complications. Twelve (35%) had pin-site infection treated with antibiotics. There was one case of non-union and no reported mal-union or deep infections. Conclusion. We report fewer complications with the use of fine-wire fixators. The infection rate is low and only limited to superficial tissues. Healing time is considerably reduced and patients are full weight bearing almost immediately. These devices are particularly effective in management of grade IIIB open distal tibial fractures with decreased time to union of tibia

Survivors of infantile meningococcal septicaemia often develop progressive skeletal deformity as a consequence of physeal damage at multiple sites, particularly in the lower limb. Distal tibial physeal arrest typically occurs with sparing of the distal fibular physis leading to a rapidly progressive varus deformity. Isolated case reports include this deformity, but to our knowledge there is no previous literature that specifically reports the development of this deformity and potential treatment options. We report our experience of 6 patients (7ankles) with this deformity, managed with corrective osteotomy using a programmable circular fixator

We report the results of using a combination of fixator-assisted nailing with lengthening over an intramedullary nail in patients with tibial deformity and shortening. Between 1997 and 2007, 13 tibiae in nine patients with a mean age of 25.4 years (17 to 34) were treated with a unilateral external fixator for acute correction of deformity, followed by lengthening over an intramedullary nail with a circular external fixator applied at the same operating session. At the end of the distraction period locking screws were inserted through the intramedullary nail and the external fixator was removed. The mean amount of lengthening was 5.9 cm (2 to 8). The mean time of external fixation was 90 days (38 to 265). The mean external fixation index was 15.8 days/cm (8.9 to 33.1) and the mean bone healing index was 38 days/cm (30 to 60). One patient developed an equinus deformity which responded to stretching and bracing. Another developed a drop foot due to a compartment syndrome, which was treated by fasciotomy. It recovered in three months. Two patients required bone grafting for poor callus formation. We conclude that the combination of fixator-assisted nailing with lengthening over an intramedullary nail can reduce the overall external fixation time and prevent fractures and deformity of the regenerated bone

Introduction. In my paediatric Orthopaedic practice I use Kirchner wires for the fixation of the TSF on bone. I noted a significant percentage of wire loosening during the post-operative period. The aim of this project was to establish the effectiveness of the wire clamping mechanism and find ways to reduce the incidence of wire loosening when using the TSF. Materials and Methods. In the first instance wire slippage was measured intra-operatively after the tensioner was removed using an intra-operative professional camera. Following this study mechanical tests were performed in the lab measuring the pull out properties of Kirchner wires using different bolts and different torque levels in order to tighten the wire on the fixator. Results. Our clinical study confirmed wire slippage intra-operatively immediately after the tensioner was removed. Wire slippage after the tensioner was removed was found to vary from 0.01 mm to 0.51 mm (mean 0.19 mm). Our mechanical tests showed that the ideal torque for tightening the wire on the frame using a bolt was around 15 N.m. A comparison between cannulated and slotted bolts suggested that cannulated bolts are more effective as a clamping mechanism. A comparison between aluminium made Taylor Spatial frame rings and stainless steel made Ilizarov rings suggested that the Taylor Spatial frame rings are more effective as part of a clamping mechanism. Conclusions. It is important that clinicians routinely measure the torque they use to clamp wires on circular external fixators. Clinicians and manufacturers are informed that the type of bolt used is important in maintaining wire tension. Manufacturers should design the ideal bolt which effectively grips the wire without the risk of fracture. The Ilizarov frame clamping mechanism can be effectively used with the Taylor Spatial frame

Background. External fixation for a fracture-dislocation to a joint like the elbow, while maintaining joint mobility is currently done after identifying the center of rotation under X-ray guidance, when applying either a mono-lateral or a circular fixator. Current treatment. using the galaxy fixation system by Orthofix, the surgeon needs to correctly identify the center of rotation of the elbow under X-ray guidance on lateral views. If the center of rotation of the fixator is not aligned with that of the elbow joint, the assembly will not work, i.e. the elbow will be disrupted on trying to achieve flexion or extension movements. Figures (A, B, C and D) summarize the critical steps in identifying the centre of rotation (Courtesy of Orthofix Orthopedics International). New design. This new idea aims to propagate the principle of sliding external fixation applied on the extensor side of a joint, with the limbs of the fixator being able to slide in and out during joint extension and flexion respectively, without hindering the joint movement. Taking the ulno-humeral joint as an example, it is enough to apply the sliding external fixator in line with the subcutaneous border of the ulna, and the pins in the sagital plane, without the need to use x-ray guidance to identify the center of rotation, which simplifies the procedure, and makes it less technically demanding. The sliding external fixator over the elbow involves two bars which accommodate half pins fixation with headless grip screws to hold the pins, identical to the Rancho cubes technique by Smith & Nephew, these slide snugly into sleeves, those sleeves linked together through a hinge behind the elbow, and the bars are spring loaded to the hinge through the inside of the sleeves, which means they will slid into the sleeves in extension and out in flexion. Length of the sleeve should prevent the bars from dislodgement, and the cross section of both the bars and the sleeves have to correspond to each other for the sleeves to accommodate the bars within them and to prevent rotational instability within the construct itself. Summary. Applying an external fixator on the extensor surface is an idea could lead to major changes in external fixation product design, the ulno-humeral joint is taken as an example, and other joints could also be addressed taking in consideration joint size and anatomical structures at risk. The sliding technique makes the application easier, without the need to X-ray guided identification of the center of rotation

Currently the debate continues in definitive fixation method for complex tibial plateau fractures. The aim of surgical management remains prevention of further damage to the articular cartilage, whilst avoiding iatrogenic risks - Low Risk Surgery (LRS). The purpose of this study was to determine the functional impact, clinical radiological outcome following tibial plateau fractures treated with either external fixation or internal fixation. 124 Schatzker IV-VI tibial plateau fractures were reviewed following surgical fixation. Fractures analysed included 24 type IV, 20 type V and 80 type VI tibial plateau fractures. The majority of Schatzker IV fractures were treated with internal fixation, but 67 of 80 Schatzker VI fractures were treated with the Ilizarov method. The average IOWA knee score, was 86 (16 to 100) and the average range of motion was 133 degrees (60 to 150). There were no differences between the circular fixator group and the internal fixation group in terms of range of motion or IOWA scores. There were comparable functional outcomes and complication rates between both groups. In summary patients with high energy tibial plateau fracture treated with internal or external fixation, have a good chance of achieving satisfactory long term knee function

Purpose of the study:. Is circular external fixation a safe and effective method of managing closed distal third tibia fractures. These fractures are conventionally treated with plaster casts, intramedullary nails or plate fixation. These treatment modalities have complication rates in the literature of up to 16% malunion, 12% non-union, and 17% deep infections. Description and Methods:. Retrospective review of 18 patients with closed distal third tibia fractures, with or without extension into the ankle joint, treated with circular fixator systems and minimal percutaneous internal fixation of the intra-articular fragment if required. Patients were followed up for time to union, malunion incidence as well as incidence of pin tract and deep infection. Distal third fractures which were extra articular or with simple intra articular extension were included. (AO 43 A, B1, C1, C2 + AO 42 in distal third) Patients with pilon fractures (AO 43 B2, B3 and C3) were excluded. Summary of results:. The average time to union in these patients was 16 weeks (11–33 weeks). The non-union rate was 11.1% in comparison to 12% with conventional treatment. The malunion rate was 0% compared to 16% with conventional treatment. The incidence of pin tract infection was 16.6%, but no deep infections were noted, whilst conventional treatment shows deep infection in up to 17%. Conclusion:. Circular external fixation is a safe and efficient option in the treatment of distal tibia fractures. The incidence of complications is significantly reduced in comparison to conventional treatment

Purpose of study. The primary treatment of congenital talipes equinus varus with the Ponsetti method remains the gold standard of treatment. Relapsed, neglected and/or teratogenic clubfeet pose a significant treatment challenge as the long term outcome of posteromedial release surgery is poor. Advances in circular fixation offer predictable deformity correction without the need for extensive soft tissue release. The Taylor Spatial Frame utilizes the correction principles of the “Ponsetti Method”, but little literature exists describing the correction of relapsed clubfeet with these fixators. This study assesses the outcome of relapsed clubfeet treated with the Taylor Spatial Frame Circular fixator. Methods. Ethics approval was obtained for a prospective descriptive study (N10-10-338). Patients with clubfeet who met inclusion criteria were treated with a Taylor Spatial Frame. The International Clubfoot Study Group Score was used to assess the feet preoperatively and six months postoperative. This scoring system scores the morphology, functionality and radiographic parameters of the clubfoot. Quality of life was assessed by means of the Child Health Questionnaire. Results. Ten feet (6 bilateral, 4 unilateral) were included in the study. Seven male and three female patients with average age of 6 years (range 3 – 13 years, sd ±4) qualified for the study. Feet were scored using the International Clubfoot Study Group Score. All feet scored poor preoperatively (average score 37±6). Postoperatively two feet scored excellent, seven good and one fair (Average score 9±4). This was statistically significant, p=0.00000. Two patients required additional surgical procedures for residual deformity. Five patients had superficial pin tract infection and one tibia fracture occurred. Conclusion. Treatment of relapsed clubfeet with the Taylor Spatial Frame gives a predictable correction of deformities without the need for extensive soft tissue and bony procedures. TSF assisted clubfoot correction constitute a useful salvage treatment modality. NO DISCLOSURES

Introduction. Open tibial fractures are associated with increased risk of complications, particularly a higher risk of infections and decreased functional outcome. Objectives. To evaluate the incidence of complications and the functional outcomes after managing open tibial fractures with circular fine-wire fixators. Methods. Retrospective review of 35 open tibial fractures treated with circular fine-wire fixators {Ilizarov and Taylor Spatial Frame (TSF)} in a teaching hospital. Patients were reviewed with x rays and clinical outcomes measured using Iowa Knee Score questionnaire, Olerud-Molander Ankle Scores (OMAS), Ankle Evaluation Score and Euroqol EQ-5D descriptive system (generic health questionnaire). Results. Ilizarov frame was used for 19 (56%) and TSF was used for 16 (44%) patients. Mean patient age was 47.1 years. 74% had high energy while 26% had low energy injury. 4 patients (12%) had grade I, 3 (9%) had grade II, 27 (79%) patients had grade III injury as per Gustilo & Anderson Classification. 14% patients had proximal, 17% had mid-shaft, 67% had distal tibial fractures respectively. Average time to union was 28.9 weeks. 12 (35%) had pin-track infection treated with antibiotics. Grade IIIB fractures healed in 29.6 weeks. 17 required soft tissue coverage and only two developed skin graft complications. There was no case of deep infection & mal-union and one patient had non-union. Patients had good satisfaction scores (EQ-5D descriptive system) following surgery (mean = 0.751). The mean Iowa Knee Evaluation score, OMAS and Ankle Evaluation score was 87.32, 73.48 and 74 respectively (maximum being 100). The ankle range of movement was similar in operated and contra lateral normal ankles. Conclusions. We report fewer complications with no incidence of deep infection rates and infection only limited to superficial tissues. Healing time is considerably reduced and there are high satisfaction rates with good functional outcomes
