Introduction. Circular external frames (CEF) are commonly used for a wide variety of indications, often when other devices are not appropriate. Circular frames are particularly associated with pin-site infection (PSI). Currently there is a gap in the available literature surrounding the risk of frame use with in-situ prosthetic joints. This retrospective study investigated the incidence of prosthetic joint infection (PJI) in a series of patients with in-situ arthroplasties treated with CEF. Materials & Methods. From a departmental database of 1052 frames performed from March 2007-March 2023, the outcomes of 34 patients (40 frames) with in-situ arthroplasties at the time of CEF were reviewed (mean follow-up 70 months). Patient identification was by review of all local and regional imaging. The primary outcome was development of PJI during or following CEF and subsequent need for surgical intervention. Secondary outcomes were development of superficial pin site or deep bone infection (without PJI). Results. Of 40 frames used to treat 34 patients, no PJIs were detected. Average patient age was 67 (range 55–82). 22 had cardio-respiratory disease, 11 diabetes, 15 smoked and 8 were immunosuppressed. 53 arthroplasties were in situ at the time of treatment, 12 involving the same bone as the frame. Average time in frame was 253 days. 23 patients developed PSI, 2 required a further procedure for persistent deep bone infection not involving the arthroplasties. Conclusions. Although this study involves a relatively low numbers of patients, our results are reassuring that circular frame management in patients with in-situ arthroplasty does not represent an unacceptable risk of PJI. We hope to promote these findings and encourage multi-centre collaboration to expand on the available evidence to better answer this important yet under-reported clinical question

Introduction. Superficial pin site infection is a common problem associated with external fixation, which has been extensively reported. However, the incidence and risk factors with regards to deep infection is rarely reported in the literature. In this study, we investigate and explore the incidence and risk factors of deep infection following circular frame surgery. For the purpose of this study, deep infection was defined as: persistent discharge or collection for which surgical intervention was recommended. Materials and Methods. Retrospective review of all patients whom underwent frame surgery between 1. st. of April 2015 to 1. st. April 2019 in our unit with a minimum of 1 year follow up following frame removal. We recorded patient demographics, patient risk factors, trauma or elective procedure, number of days the frame was in situ, location of infection and fracture pattern. Results. 304 patients were identified. 27 patients were excluded as they were lost to follow up or had their primary frame surgery as a treatment for infection. This provided us with 277 patients for analysis. Mean age was 47 years (range 9–89 years), the male to female ratio was 1.5:1 and 80% were trauma frames. 13 patients (4.69%) developed deep infection and all occurred in trauma patients. Of the 13 patients who developed deep infection, 4 had infection before frame removal and 9 occurred after frame removal. 8 deep infections occurred within a year of frame removal, 1 occurred between 1 and 2 years. Within the 13 frame procedures for trauma, 12 were periarticular multifragmentary fractures, 3 of which were open, and the remaining was an open diaphyseal fracture. The periarticular fractures were more likely to develop deep infection than diaphyseal fractures (p–0.033). 12 patients (out of 13) also had concurrent minimally invasive internal fixation with screws in very close proximity of the wires. Conclusions. The rate of deep infection following circular frame surgery appears to be low. Pooled, multicentre data would be required to analyse risk factors however multifragmentary, periarticular fracture and the requirement for additional internal fixation appears to be an associated factor

Introduction. Open tibial fractures typically occur as a consequence of high energy trauma in patients of working age resulting in high rates of deep infection and poor functional outcome. Whilst improved rates of limb salvage, avoidance of infection and better ultimate function have been attributed to improved centralisation of care in orthoplastic units, there remains no universally accepted method of definitive management of these injuries. The aim of this study is to the report the experience of a major trauma centre utilising circular frames as definitive fixation in patients sustaining Gustilo-Anderson (GA) 3B open fractures. Materials & Methods. A prospectively maintained database was interrogated to identify all patients. Case notes and radiographs were reviewed to collate patient demographics and injury factors . The primary outcome of interest was deep infection rate with secondary outcomes including time to union and secondary interventions. Results. 247 open tibial fractures with a soft tissue manipulation in order to achieve skin cover, of which 203 had a minimum follow up of 2 years. Mean age was 43.2 years old, with 72% males, 34% smokers and 3% diabetics. Total duration of frame management averaged 6.4 months (SD 7.7). Nine (4.4%) patients developed a deep infection and 41 (20%) exhibited signs of a pin site infection. Seventy-five (37%) of patients had a secondary intervention of which; 8 comprised debridement of deep infection, 1 amputation for deep infection and the remainder adjustments of frames. Conclusions. Orthoplastic care including circular frame fixation for GA 3B fractures of the tibia results in a low rate of deep infection, around a quarter of contemporary literature for internal fixation

Open fractures of the long bones of the limbs are associated with an increased risk of osteomyelitis and few studies investigate this complication in circular frames. We reviewed the incidence of and contributory factors toward infection-related outcomes in Grade 3 open fractures, managed with a circular frame, at a single centre. We performed a retrospective study of consecutive adult patients presenting with a Grade 3 open fracture, who required a circular frame for definitive skeletal fixation from 2005 to 2014. Patient case notes, microbiology results and radiological studies were reviewed for demographic details and surgical management. Infection-related outcomes were classified as ‘possible’ and ‘definitive’, based on clinical findings, microbiology and imaging features at follow-up at 6 and 12 months. 74 patients were identified with an average age of 43 years. There were 70 unilateral and 4 bilateral limb injuries. Most treated limbs had a tibial fracture (97%). There were 24 Gustillo-Anderson grade 3A, 37 grade 3B, 4 grade 3C and 9 not sub-classified. 33% of patients were debrided on the day of injury. Average time to circular frame installation was 14 days. 27 Ilizarov, 44 Taylor spatial and 3 other circular frames were used. A variety of plastic surgery reconstruction was used to provide wound coverage: skin grafts, local and free flaps. Circular frames were in place for 259 days on average. 10 patients (1 bilateral limb fracture) still have their frames in-situ. Additional bone grafting to the fracture site was carried out in 13 patients and 15 limbs (1 patient had 2 episodes of bone grafting to the same limb). 8 limbs in 8 patients were excluded from infection-related outcome analysis: 4 patients lost to follow-up, 2 patients who went on to below knee amputation and 2 patients had <6 months’ follow-up. 13 patients (14 limbs) had only 6 months’ follow-up and 53 patients (56 limbs) had 12 months’ follow-up. There were 5 patients (5 limbs) with ‘possible’ infection (7%): 1 screw infection and 4 soft tissue infections. 1 patient (1 limb) had a tissue-confirmed ‘definitive’ infected non-union (1.4%). Patients managed with circular frames typically have complex fracture configurations less amenable to other methods of definitive fixation. Our patient cohort has a limb salvage rate (97%) and a soft tissue infection rate (‘possible’ infection) comparable to other reported series. We report a low rate of osteomyelitis (‘definitive’ infection) in consecutive patients managed using our protocol

Statement of Purpose. To compare the functional outcome of Distal Tibial Metaphyseal fracture treated with Circular frame compared vs. Locking Plate. Methods and Results. Distal Tibial Metaphyseal fractures were retrospectively identified over an 18 month period. Each fracture was assessed individually using radiographs. All paediatric, compound, tibial plateau and intra-articular fractures were excluded from the study. Other methods of fixation including intramedullary nailing were also excluded. The remaining fractures were assigned to either the circular frame fixation or the locking plate intervention group. Outcomes were assessed using radiographs for union dates and microbiology results for evidence of infection. Patients were followed up by postal questionnaires, which included a modified American Orthopaedic Foot and Ankle Score (AOFAS), the Olerud and Molander Score (O&M) and a custom questionnaire. The custom questionnaire asked about co-morbidities, smoking status and work days lost following surgery. After exclusions, 30 patients (Frame=15, Plate=15), were sent out questionnaires via post. We received completed questionnaires from 21 patients (Frame=11, Plate=10) giving us a response rate of 70%. Results show no difference in infection rates, skin necrosis, non-union or re-operation rates. There was also no significant difference in patient AOFAS and O&M scores at follow up. Conclusion. There is no significant difference in complications and functional Outcomes between locking plate fixation and circular frames in the treatment of distal Tibial Metaphyseal fractures

Methods:. Total radiation exposure accumulated during circular frame treatment of distal tibial fractures was quantified in 47 patients treated by a single surgeon from March 2011 until Nov 2014. The radiation exposures for all relevant radiology procedures for the distal tibial injury were included to estimate the radiation risk to the patient. Results:. The median time of treatment in the frame was 169 days (range 105 – 368 days). Patients underwent a median of 13 sets of plain radiographs; at least one intra operative exposure and 16 patients underwent CT scanning. The median total effective dose per patient from time of injury to discharge was 0.025 mSv (interquartile range 0.013 – 0.162 and minimum to maximum 0.01–0.53). CT scanning is the only variable shown to be an independent predictor of cumulative radiation dose on multivariate analysis, with a 13 fold increase in overall exposure. Conclusion:. Radiation exposure during treatment of distal tibial fractures with a circular frame in this group was well within reasonably safe limits. CT was the only significant predictor of overall exposure serves as a reminder to individually assess the risk and utility of radiological investigations on an individual basis. This is consistent with the UK legal requirements (Ionising Radiation (Medical Exposure) Regulations 2000. 1. )

Tibial non-union causes significant morbidity and functional impairment. Circular frames are valuable tools in the treatment of non-union, however prolonged treatment often causes patients increased morbidity due to pin site problems together with personal and emotional strains. The purpose of this study was to assess patient centred outcomes following treatment of tibial non-union in circular frame. We identified 21 patients who had undergone treatment of tibial non-union using a circular frame. Patients were sent questionnaires utilising the Enneking scoring system and EQ-5D general health questionnaire. Fourteen patients responded. There were 3 females, mean age was 48.2 years. The average number of previous operations was 1.2. All patients went on to achieve union with a mean 10.1 months (6–20) in frame. The mean Enneking score was 58.0% (34.3–77.1). Two patients were enthusiastic about their treatment, two liked it, three were satisfied, four accepted and would do it again while three accepted it but would not do it again. The Euroqol questionnaire results showed that 8 patients had some difficulty with mobility, 10 had some difficulty with usual activities and 12 moderate pain. There was no significant difference in the EQ VAS score of overall health state for treated patients compared with predicted scores for an age and sex matched UK population (77.7 vs 83.1, p=0.07). Our study shows that many patients undergoing limb salvage with circular frames for tibial non-union continue to have clinically significant symptoms, however the majority would undergo similar treatment again and we found no difference in overall health state compared with age and sex matched predicted scores. Circular frames are undoubtedly a valuable tool in the management of non-union however patients should be given realistic counselling regarding the treatment and expected outcome

Introduction. Introduction: Pre-operative counselling to prepare patients for frame surgery is important to ensure expectations of recovery and rehabilitation are realistic and anxiety is reduced. The aim of the study was to ascertain whether the current clinical nurse specialist frames counselling session (CNS FCS) prepared patients adequately for life with a frame as well as to explore information patients felt was missing. Materials & Methods. Materials and Method: Patient reported questions were used to assess frames patient views on the CNS FCS. Thirty frames patients were asked about the CNS FCS information, involvement in decision making, factors influencing frames surgery decision and patient experience. Results. Results: There were 27 patients who received CNS frames counselling and 82% of those (N=22) said they definitely received enough information to make a decision when faced with a choice of surgical plans. 85% (N=23) reported definitely feeling involved in the decision making process with factors contributing to choosing frame treatment being lower risk of deep infection, quicker / safer recovery and advice from the limb reconstruction team. 48% (N=13) definitely felt the CNS FCS gave them a realistic idea of what it's like to live with a frame and 52% (N=14) answered yes to some extent. Feedback on providing more information around sleeping with a frame was provided which has been added to future CNS FCS. Conclusions. Conclusion: The current CNS FCS does prepare patients for frames surgery and life with a circular frame and important points raised by patients in this study have been added to future patient information sessions. Regular patient satisfaction audits should be carried out to ensure information remains useful and current patient needs and concerns are met

Statement of purpose. Circular frames treatment for limb reconstruction involves repeated follow up visits, and a substantial number of these appointments are for pin site review only, and incur a significant cost to the NHS. We advocate ‘Telemedicine’ as a logistically and economically viable option for routine post-operative review of pin-sites. Methods and results. The senior author performs fifty to sixty frame circular frame treatments in adults for trauma every year. For the past 12 months, we have been encouraging our frame patients to take photographs of their pin-sites when they do their weekly dressing changes. This is done with digital cameras by the patients themselves, and the images are then emailed to the senior author on his work email address, and get replied to by the next day. If the images are a cause for concern, further steps are initiated (Images 1 and 2 demonstrate pin-sites before and after a course of antibiotics, started because the first image was a cause for concern). This arrangement is for pin-site reviews only. This method has been used for the post-op pin site review of five patients with circular frames. Conclusion. We have so far experienced a high level of patient satisfaction and significant benefits with pin-site telesurveillance in our limited number of patients, and plan to incorporate this as a formal protocol in our practice

Introduction: Arthrodesis of the knee nowadays is used as a salvage procedure, commonly for patients with a failed TKR or in infected trauma cases. We present 4 patients with extensive bone defects following septic sequelae of trauma treated by Arthrodesis of the knee joint. Materials and Methods: Four patients (avg. 46.5 years; range 37–57 years; three male and one female) with longstanding infected non-union fractures (3 months–2 years) at the knee joint (three Tibial plateau and one distal femur) were treated by initial debridement and removal of dead or infected bone. This led to substantial bone defects (6–12 cm) of the debrided bone at the knee joint. The patients then underwent bone transport with a circular frame to compensate for this bone defect before achieving an Arthrodesis of the knee joint. Three patients also had a free muscle flap for soft tissue coverage before bone transport was begun. Results: Arthrodesis of the knee was achieved in all patients at an average time of 26 months (20–32 months). None of the patients have any active infection of the limb. Discussion and Conclusions: Knutson et al (1984) said that massive bone loss may substantially reduce the success rate of Arthrodesis of the knee. Wilde and Stearns (1989) noted decreased fusion rates with greater degrees of bone loss. In our series the bone defects were a sequelae of infective non–union, this further complicates the healing process. However, using circular frame for Bone transport to overcome the defect and to achieve compression at the Arthrodesis site is a useful technique for such challenging cases

Introduction. The optimal management of intra-articular tibial plateau fractures with metaphyseal-diaphyseal dissociation remains challenging and controversial. We report results using the technique of limited open reduction with external fixation using a fine wire circular frame. Method. Between 1994 –2006, 83 eligible patients were identified. Case notes were reviewed; X-Rays and CT scans were examined and used to rank-order the severity of injury. ‘Musculoskeletal Functional Assessment’ (MFA) and ‘Knee Outcome Survey’ (KOS) questionnaires were completed and axial alignment X-Rays were taken to assess functional and radiological outcome. Results. 47 patients were available for follow-up at mean 57 months post injury. All fractures had united. There were 3 cases (6.39%) of pin site infection that necessitated debridement of superficial soft tissues. There were no cases of deep infection. Functional outcome. The mean MFA score was 24.7 points (range, 2 to 68 points). Leisure & recreation (51.06), mobility (37.02) and emotional score (33.22) were most affected. The mean KOS was 73.11 (range, 18.75 to 96.25). When compared to control population, our patient cohort still have significant persistent levels of disability. No correlation was found between severity of injury, nor any patient demographic factors and functional outcome. 26 patients (85.1%) had returned to employment, though 29.8% had either been forced to change occupation or were limited in their original occupation by their injury. Radiological outcome. Knee subluxation was found to have a significant association with poorer MFA (-0.323 p = 0.028) and KOS scores (0.304 p = 0.04). No other radiological measures correlated with functional outcome. Conclusion. Treatment of these severe injuries by circular frame and limited internal fixation is a safe and effective operative option. It offers early mobilisation and movement of the knee, with a low complication rate and functional outcome equivalent to other treatment modalities

Introduction

Fracture healing is governed by biological and mechanical factors. Circular frames are one method to fix fractures. Recently, the number of frame designs that are available has increased and these different designs may have different effects on the mechanical environment created. The senior author has been concerned by the stability of the construction when a short frame is used. This study examined the stability of different frames and the possible use of additional 7th struts to aid stability.

Ilizarov frame removal often occurs in the outpatient setting, and previous data has shown it can be a painful experience. Frames with a total of four or more olive wires or half-pins in combination yielded increased pain scores at frame removal.

Sublingual fentanyl provides rapid onset, short acting analgesia for painful procedures such as dressing changes in burns patients. We hypothesised that administration of sublingual fentanyl, prior to frame removal would improve patients' pain scores.

Twenty-one patients were given 100 mcg sublingual fentanyl prior to frame removal. Their pain scores were documented on an 11-point (0–10) numeric visual scale before, immediately after, 15 and 30 minutes after frame removal, and the following day. The same nurse specialist removed all the frames. Nitrous oxide was available for patients if they needed further analgesia.

The majority of frames were removed from tibia. The average patient age was 40.8 years. Each frame had a median of 9 wires (range 2–17), and 4 olives (2–8). Eight frames had half pins (range 1–4, median 2). Fourteen patients used nitrous oxide in addition to fentanyl.

Overall, the average pain score was 3.1. This peaked at 7.5 immediately after frame removal, but 15 minutes following removal the average was 2.5. Patients who had supplementary nitrous oxide had higher pain scores throughout (though not beforehand), although these differences were not statistically significant.

Four patients (19%) reported adverse effects following administration, but none required medical intervention.

Patients' pain scores averaged 2.52 within 15 minutes of removal, compared with 5.25 from our previous review. This suggests that fentanyl may be beneficial in frame removal, but our sample size was small, and more research is needed in this area.

Purpose. Pilon fracture is a severe injury which has a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the gait alternations after treatment of patients who had pilon fractures. Materials & Methods. We have evaluated the gait pattern of patients who were treated with circular Ilizarov frame following pilon fractures in our department. The gait was tested by using a force plate in a walking platform. Ground Reaction Forces (GRF) and timing of gait phases data were collected during level walking at self-selected speeds. The patients performed two walking tasks for each limb and the collected data were averaged for each limb. Demographic, clinical, radiological, trauma outcome (COST) and quality of life questionnaire (SF-12) data were also collected. Results. We have analysed the gait through the GRF of twelve patients (aged 44.9 ±12.4 years), who had undergone treatment with circular Ilizarov frame following pilon fractures (67% were male). The tests were performed at an average of 10.5 months after the initial treatment. SF-12 Mental scores have returned to normal (mean 56.4 ±11.6) but physical scores remained impaired (mean 41.8 ±8.4). COST questionnaire scores reached average levels (47.1 ±15) in all dimensions (Symptoms: 51.4 ±16, Function: 44 ±14 and Mental Status: 56.6 ±16). During the push-off phase all the plantar flexor muscles are activated and the ankle plantar flexes to achieve the push off. It seems that this motion, is not achieved adequately with the affected limb and the patients are using their normal limb earlier (pre-swing is the start of the double support of the gait) in order to progress in their gait circle. Conclusions. Ten months following treatment with circular ilizarov frame for pilon fracture the patients still have impaired gait pattern. The differences can be explained by the lack of plantar flexion of the ankle which results to poorer push-off of the affected limb

Purpose. Tibia plateau fractures are severe knee injuries which have a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the gait alternations after treatment of patients who had severe tibia plateau fractures which were treated with circular ilizarov frame. Materials & Methods. We have evaluated the gait pattern of patients who were treated with circular Ilizarov frame after severe tibia plateau fractures (Schatzker IV-VI) in our department. The gait was tested by using a force plate in a walking platform. Ground Reaction Forces (GRF) data were collected during level walking at self-selected speeds. The patients performed two walking tasks for each limb and the collected data were averaged for each limb. Demographic, clinical, radiological and quality of life questionnaire (SF-12) data were also collected. Results. We have analysed the gait through the GRF of fifteen patients (aged 50.8 ±17.3 years), who had undergone treatment with circular Ilizarov frame following severe tibia plateau fractures (Schatzker IV-VI). Nine were male and six were female. The tests were performed at an average of 13.2 months after the initial treatment. SF-12 Mental scores have returned to normal (mean 54.6 ±12.3) but physical scores remained impaired (mean 40.6 ±10.8). A one-way repeated measures ANOVA was conducted to compare the GRFs and gait timing data of the affected limb with the normal one. Single limb support interval was significantly reduced to the affected limb (p=0.001) and terminal stance phase was prolonged for the normal limb (p=0.035). During this phase of the gait circle the knee is on its maximum flexion and the quadriceps contracts to bring the femur above the tibia. It seems that these patients during the gait circle reduce the flexion of their affected knee to make their single stance shorter. To the normal limb the patients manage to reduce more the GRFs during the mid-stance phase (F2 force), this difference do not reach significance, but illuminates the tendency of reduced knee flexion in that phase. The rest of the GRF and gait timing data did not had significant differences. Conclusions. One year after severe tibia plateau fracture treated with circular ilizarov frame the patients manage to return to almost normal gait pattern. Reduce single limb stance and terminal stance phase to the affected knee can be explained by the tendency of not flexing their deficient knee as much during that gait phase

Aims. Pin-site infection remains a significant problem for patients treated by external fixation. A randomized trial was undertaken to compare the weekly use of alcoholic chlorhexidine (CHX) for pin-site care with an emollient skin preparation in patients with a tibial fracture treated with a circular frame. Methods. Patients were randomized to use either 0.5% CHX or Dermol (DML) 500 emollient pin-site care. A skin biopsy was taken from the tibia during surgery to measure the dermal and epidermal thickness and capillary, macrophage, and T-cell counts per high-powered field. The pH and hydration of the skin were measured preoperatively, at follow-up, and if pin-site infection occurred. Pin-site infection was defined using a validated clinical system. Results. Out of 116 patients who were enrolled in the study, 23 patients (40%) in the CHX group and 26 (44%) in the DML group had at least one bad or ugly pin-site infection. This difference was not statistically significant (p = 0.71). There was no significant relationship between pH or hydration of the skin and pin-site infection. The epidermal thickness was found to be significantly greater in patients who had a pin-site infection compared with those who did not (p = 0.01). Skin irritation requiring a change of treatment occurred in four patients (7%) using CHX, and none using DML. Conclusion. We found no significant difference in the incidence of pin-site infection between the CHX and DML treatment groups. Dermol appeared to offer a small but significant advantage in terms of tolerability. We did not find a significant association between patient or treatment related factors and pin-site infection. It is therefore difficult to make specific recommendations based upon these results. The use of either cleaning agent appears to be appropriate. Cite this article: Bone Joint J 2021;103-B(2):279–285

Early methods of treating high-energy tibial plateau fractures by open reduction and internal fixation led to high infection rates and complications. Alternative treatment methods include minimally invasive techniques and implants, external fixator stabilisation (monolateral and circular) and temporary external fixation followed by delayed definitive surgery. A clear understanding of the different fracture types is critical in achieving optimum results with minimally invasive techniques. The Chertsey classification system is based on the direction of force at the time of injury and helps with surgical planning. There are three groups: valgus, varus or axial fracture patterns.

124 tibial plateau fractures have been surgically treated in our hospital since 1995; there were 62 valgus, 14 varus and 48 axial type fracture patterns. Seventy-nine underwent open reduction with internal fixation, and forty-five had an Ilizarov frame. For valgus fractures the average IOWA knee score was 88 if internally fixed or 86 with an Ilizarov frame, range of motion was 140 and 131 degrees and time to union was 81 versus 126 days respectively. Varus fractures had an IOWA score of 83 (ORIF) and 95 (Ilizarov), ROM of 138 and 130 degrees and time to union of 95 versus 82 days. For axial fractures the average IOWA knee score was 85 (ORIF) compared to 82 (Ilizarov), the ROM was 124 degrees for both groups and time to union was 102 days and 141 days respectively.

Deep vein thrombosis occurred in 9% of cases with an Ilizarov and one patient required a total knee replacement for painful post-traumatic osteoarthritis. The infection rate for those internally fixed was 2.5%, three patients required a total knee replacement and 2.5% suffered a DVT.

Our results are comparable to the literature and the Chertsey classification of tibial plateau fractures helps with surgical planning.

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.

Aims

The aim of this study was to report the clinical, functional and radiological outcomes of children and adolescents with tibial fractures treated using the Ilizarov method.
