Aims

This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme.

Introduction. Positive reports from implant designer centres on the use of fibular nails in the complex ankle fractures has resulted in a marked increase in their use nationally. Our aim in this study was to report on the outcomes of the use of all fibular nails in two major trauma centres. Methods. All patients who underwent ankle fracture fixation using a fibular nail in two major trauma centres, were included for analysis. MTC 1 included patients from April 2013 to May 2015, and MTC 2 included patients February 2015 to March 2018. A minimum follow up of 1 year was achieved for all patients. Radiographic reduction was confirmed by Pettrones criteria at time of operation and at 6 weeks and 1 year post-operatively. Kellgren Lawrence radiographic criteria was used to classify osteoarthritis. All complications and further surgery were recorded. Results. Forty-four patients underwent fibular nail fixation in the two centres. The average age was 59 (range 21–91). Using Pettrones criteria, 86% were malreduced at time of operation. A further 34% deteriorated by at least 1 grade by 6 weeks and an additional 16% (n=7) deteriorated by at least 1 grade by 1 year. 57% had developed radiographic evidence of osteoarthritis by 1 year. Only 4.5% (2ankles) maintained complete reduction by 1 year. Other significant complications were reported in 43% of patients. Conclusion. Both major trauma centres report the same experience in the use of fibular nails for ankle fracture fixation. As previously reported in smaller number studies, initial reduction is challenging. Worryingly, the majority of well-reduced lose position with time. We suggest that the fibula nail is used with caution and as part of an appropriately approved audit

Ankle fractures are among the most common types of fractures. If surgery is not performed within 12 to 24 hours, ankle swelling is likely to develop and delay the operative fixation. This leads to patients staying longer in the ward waiting and increased hospital occupancy. This prolonged stay has significant financial implication as well as it is frustrating for both patients and health care professionals. The aim was to formulate a pathway for the ankle fracture patients coming to the emergency department, outpatients and planned for operative intervention. To identify whether pre-operative hospital admissions of stable ankle fracture patients are reduced with the implementation of the pathway. We formulated an ankle fracture fixation pathway, which was approved for use in December 2020. A retrospective analysis of 6 months hospital admissions of ankle fracture patients in the period between January to June 2020. The duration from admission to the actual surgery was collected to review if some admissions could have been avoided and patients brought directly on the surgery day. A total of 23 patients were included. Mean age was 60.5 years and SD was 17years. 94% of patients were females. 10 patients were appropriately discharged.7 Patients were appropriately admitted. 6 Patients were unnecessarily admitted. These 6 patients were admitted on presentation to ED. Retrospective analysis of this audit showed that this cohort of patients met the safe discharge criteria and could have been discharged. Duration of unnecessary stay ranged from 1 to 11 days (21 days in total). Total saving could have been £6300. Standards were met in 74% of cases. Preoperative hospital admission could be reduced with the proposed pathway. It is a valuable tool to be used and should be implemented to reduce unnecessary hospital admissions

Introduction. Ankle fractures represent approximately 10% of the fracture workload and are projected to increase due to ageing population. We present our 5 years outcome review post-surgical management of ankle fractures in a large UK Trauma unit. Methods. A total of 111 consecutive patients treated for an unstable ankle fracture were entered into a database and prospectively followed up. Baseline patient characteristics, complications, further intervention including additional surgery, functional status were recorded during five-year follow-up. Pre-injury and post-fixation functional outcome measures at 2-years were assessed using Olerud-Molander Ankle Scores (OMAS) and Lower Extremity Functional Scales (LEFS). A p value < 0.05 was considered significant. Results. The mean age was 46 with a male:female ratio of 1:1.1. The distribution of comorbidities was BMI >30 (25%), diabetes (5%), alcohol consumption >20U/week (15%) and smoking (26%). Higher BMI was predictive of worse post-op LEFS score (p = 0.02). Between pre-injury and post fixation functional scores at 2 years, there was a mean reduction of 26.8 (OMAS) and 20.5(LEFS). Using very strict radiological criteria, 31 (28%) had less than anatomical reduction of fracture fragments intra-operatively. This was, however, not predictive of patients' functional outcome in this cohort. Within 5-year period, 22 (20%) patients had removal of metalwork from their ankle, with majority 13 (59%) requiring syndesmotic screw removal. Further interventions included: joint injection (3), deltoid reconstruction (1), arthroscopic debridement (1), superficial sinus excision (2), and conversion to hindfoot nail due to failure of fixation (1). Reduction in OMAS was predictive of patients' ongoing symptoms (p=0.01). Conclusion. There is a significant reduction in functional outcome after ankle fracture fixation and patients should be counselled appropriately. Need for removal of metalwork is higher in patients who require syndesmosis stabilisation with screw(s)

Classification systems for the reporting of surgical complications have been developed and adapted for many surgical subspecialties. The purpose of this systematic review was to examine the variability and frequency of reporting terms used to describe complications in ankle fracture fixation. We hypothesized that the terminology used would be highly variable and inconsistent, corroborating previous results that have suggested a need for standardized reporting terminology in orthopaedics. Ankle fracture outcome studies meeting predetermined inclusion and exclusion criteria were selected for analysis by two independent observers. Terms used to define adverse events were identified and recorded. If a difference occurred between the two observers, a third observer was enlisted. Results of both observers were compared. All terms were then compiled and assessed for variability and frequency of use throughout the studies involved. Reporting terminology was subsequently grouped into 10 categories. In the 48 studies analyzed, 301 unique terms were utilized to describe adverse events. Of these terms, 74.4% (224/301) were found in a single study each. Only one term, “infection”, was present in 50% of studies, and only 19 of 301 terms (6.3%) were used in at least 10% of papers. The category that was most frequently reported was infection, with 89.6% of studies reporting on this type of adverse event using 25 distinct terms. Other categories were “wound healing complications” (72.9% of papers, 38 terms), “bone/joint complications” (66.7% of papers, 35 terms), “hardware/implant complications” (56.3% of papers, 47 terms), “revision” (56.3% of papers, 35 terms), “cartilage/soft tissue injuries” (45.8% of papers, 31 terms), “reduction/alignment issues” (45.8% of papers, 29 terms),“medical complications” (43.8% of papers, 32 terms), “pain” (29.2% of papers, 16 terms) and “other complications” (20.8% of papers, 13 terms). There was a 78.6% interobserver agreement in the identification of adverse terms across the 48 studies included. The reporting terminology utilized to describe adverse events in ankle fracture fixation was found to be highly variable and inconsistent. This variability prevents accurate reporting of adverse events and makes the analysis of potential outcomes difficult. The development of standardized reporting terminology in orthopaedics would be instrumental in addressing these challenges and allow for more accurate and consistent outcomes reporting

Is Non-Weight-Bearing Necessary? (INWN) is a pragmatic multicentre randomised controlled trial comparing immediate protected weight-bearing (IWB) with non-weight-bearing cast immobilisation (NWB) following ankle fracture fixation (ORIF). This trial compares; functional outcomes, complication rates and performs an economic analysis to estimate cost-utility. IWB within 24hrs was compared to NWB, following ORIF of all types of unstable ankle fractures. Skeletally immature patients and tibial plafond fractures were excluded. Functional outcomes were assessed by the Olerud-Molander Ankle Score (OMAS) and RAND-36 Item Short Form Survey (SF-36) taken at regular follow-up intervals up to one year. A cost-utility analysis via decision tree modelling was performed to derive an incremental cost effectiveness ratio (ICER). A standard gamble health state valuation model utilising SF-36 scores was used to calculate Quality Adjusted Life Years (QALYs) for each arm. We recruited 160 patients (80 per arm), aged 15 to 94 years (M = 45.5), 54% female. Complication rates were similar in both groups. IWB demonstrated a consistently higher OMAS score, with significant values at 6 weeks (MD=10.4, p=0.005) and 3 months (MD 12.0, p=0.003). Standard gamble utility values demonstrated consistently higher values (a score of 1 equals perfect health) with IWB, significant at 3 months (Ẋ = 0.75 [IWB] / 0.69 [NWB], p=0.018). Cost-utility analysis demonstrated NWB is €798.02 more expensive and results in 0.04 fewer QALYs over 1 year. This results in an ICER of −€21,682.42/QALY. This negative ICER indicates cost savings of €21,682.42 for every QALY (25 patients = 1 QALY gain) gained implementing an IWB regime. IWB demonstrates a superior functional outcome, greater cost savings and similar complication rates, compared to NWB following ankle fracture fixation

Background. The aim of our study was to assess the ability of orthopaedic surgical trainees to adequately assess ankle radiographs following operative fixation of unstable ankle fracture. Methods and results. We identified 26 Supination-External rotation (SER) stage IV fractures, and 4 Pronation-External rotation (PER) stage III fractures treated surgically in our institution. Radiographs were evaluated for shortening of the fibula, widening of the joint space, malrotation of the fibula and widening of the medial clear space. Trainees were shown these radiographs and asked to comment on the adequacy of reduction. They were then given a simple tutorial on assessing adequacy of reduction and asked to reassess these radiographs. The parameters discussed included assessment of medial clear space, drawing of the tibiofibular line, use of the “circle sign” and measurement of the talocrural angle. There was a statistically significant improvement from 64% to 71.4% (P< 0.05) in the radiographs correctly assessed by orthopaedic trainees following a short tutorial on radiographical assessment. Conclusions. Despite the frequency with which junior surgical trainees deal with ankle fractures, there is a lack of awareness on the objective means of adequately assessing ankle fracture fixation. We highlight this deficiency and demonstrate that a short tutorial on radiographic parameters results in improved assessment and better critical analysis of adequacy of reduction following ankle fracture fixation. As with fractures about the wrist, careful assessment of radiographic parameters should be considered standard practice in assessment of adequacy of reduction in fractures about the ankle

Purpose: The aim of this study was to compare the results and length of stay of patients of early ankle fracture fixation with conventional fixation in a busy District General Hospital in UK. Method: A retrospective study was conducted using data from case records, electronic patient record, clinical coding information, clinic letters and Picture Archiving and Communications System (PACS). Two hundred patients who underwent ankle fracture fixation from July 2004 to June 2005 were included. We looked into age, place of living, Weber classification, mechanism of injury, comorbidities especially diabetes and peripheral vascular disease, addictions mainly smoking, whether patient was anticoagulated, delay for theatre with reasons, length of stay in hospital and complications if any. Other things to looked at were, overlying skin condition, the amount of swelling at the time of presentation to A& E, associated ankle dislocation or talar shift needing reduction, injury types-open or closed or with associated neuro-vascular injury. In-operative management – what method was used ie malleolar screws, diastasis screw, fibular plating, calcaneotalotibial nail or external fixater etc. Results: In the 12-month retrospective review, there were 200 ankle fractures that required surgical intervention. Only twenty-two of these had surgery within 12 hours (mean length of stay, 3.3 days), and sixty-seven of these had surgery within 48 hours (mean length of stay, 4.9 days), and 111 had surgery after 48 hours (mean length of stay, 9.4 days). Finally we calculated the cost (784 bed days – £235 thousands) incurred to the trust in terms of extra bed occupancy and treating the complications as a result of wait. Conclusion: This study shows that early operative intervention for ankle fractures reduces the length of hospital stay. Intensive physiotherapy and co-ordinated discharge planning are also essential ingredients for early discharge. We want to emphasise on the ‘Window of Opportunity’ ie initial 12 hours to fix ankle fractures to decrease overall morbidity and cost

The timing of surgery in treating closed ankle fractures requiring open reduction and internal fixation is dependent upon soft tissue swelling. At Exeter in 2001 one third of all trauma cases were operated on “out of hours,” in 2007 this was less than 10%, principally as a result of the lack of anaesthetic staff. The senior author has developed a technique of minimally invasive percutaneous plate osteosynthesis for ankle fracture fixation that may be undertaken at an early stage, despite the presence of swelling. In a retrospective study 25 patients fixed with percutaneous osteosynthesis over four years were compared with a cohort of 25 patients selected at random who had undergone standard open reduction and internal fixation in the same time period. Particular attention was paid to time to surgery, time to discharge and complications. Patients undergoing percutaneous fixation were found from the hospital database. One patient was excluded because of a delay to surgery whilst being treated on the intensive care unit. Admission documentation, operation notes and clinic letters were used to ascertain the outcome. Pre and post-operative imaging was evaluated. Over a four-year period the senior author performed minimally invasive percutaneous plate osteosynthesis on a total of 25 patients. The mean time to surgery was two days for the percutaneous cohort (range 0–5 days) compared with 4.1 days for the open cohort (range 1–11). Time to discharge was 4.2 days as opposed to 6.2 in the percutaneous group. There were no complications in the percutaneous cohort, as opposed to three in the standard cohort. Preliminary results demonstrate a reduced waiting time for surgery and a quicker discharge when using minimally invasive percutaneous plate osteosynthesis technique for ankle fracture fixation. We believe that our institution is the first to develop this technique. Percutaneous fixation is an option when swelling precludes open surgery

Introduction:. Inadequate reduction and fixation of ankle fractures leads to poor clinical outcomes although there are no well-established criteria to evaluate the quality of surgical fracture fixation of the ankle. The aim of our study was to validate Pettrone's criteria that can be used in the radiological assessment of the quality of ankle fracture fixation that predict the functional outcome. Methods:. A retrospective study was completed following the operative management of ankle fractures at a University teaching hospital between 1. st. January 2009 and 31. st. December 2009 were included in the study. Exclusion criteria were paediatric fractures, polytrauma, and fractures involving the tibial plafond. The fracture pattern was classified using the AO classification system. Three independent Foot and Ankle Consultants assessed the quality of surgical ankle fracture fixation using Pettrone's criteria. Approximately one year following the surgery, functional outcome was obtained using Lower Extremity Function Score (LEFS) and a modified American Orthopaedic Foot and Ankle Society score (AOFAS). The Mann-Whitney test was used for the LEFS and AOFAS functional scores. Logistic regression was performed upon age and gender with regards to functional outcome. Given that the Kappa coefficient is a pair wise statistic, the average pair wise agreement for each category of the Pettrone criteria was also determined. Results:. Sixty-one consecutive patients were included in the study with a mean age of 51 years (17–74 years) and a mean follow-up of 17.41 months (13–24 months). Using Pettrone's criterias, mean interobserver agreement was 90.0% (89.4–92.6%) with inadequate reduction in 20 cases (32.5%). Mean LEFS following inadequate reduction was 47.5 (1–79) and following satisfactory reduction was 55.9 (9–80) p=0.03. Conclusion:. Pettrone's criteria has high interobserver agreement for the quality of surgical fracture fixation of the ankle which correlates with functional outcome

Introduction

Ankle fractures in the elderly are an increasing problem with our aging population. Options for treatment include non-operative and operative with a range of techniques available. Failure of treatment can lead to significant complications, morbidity and poor function. We compared the outcomes of two operative techniques, intramedullary hindfoot nailing (IMN) and fibular-pro-tibia fixation (FPT). This is the largest analysis of these techniques and there are no comparative studies published.

Aims. Ankle fracture fixation is commonly performed by junior trainees. Simulation training using cadavers may shorten the learning curve and result in a technically superior surgical performance. Methods. We undertook a preliminary, pragmatic, single-blinded, multicentre, randomized controlled trial of cadaveric simulation versus standard training. Primary outcome was fracture reduction on postoperative radiographs. Results. Overall, 139 ankle fractures were fixed by 28 postgraduate year three to five trainee surgeons (mean age 29.4 years; 71% males) during ten months' follow-up. Under the intention-to-treat principle, a technically superior fixation was performed by the cadaveric-trained group compared to the standard-trained group, as measured on the first postoperative radiograph against predefined acceptability thresholds. The cadaveric-trained group used a lower intraoperative dose of radiation than the standard-trained group (mean difference 0.011 Gym. 2. , 95% confidence interval 0.003 to 0.019; p = 0.009). There was no difference in procedure time. Conclusion. Trainees randomized to cadaveric training performed better ankle fracture fixations and irradiated patients less during surgery compared to standard-trained trainees. This effect, which was previously unknown, is likely to be a consequence of the intervention. Further study is required. Cite this article: Bone Jt Open 2023;4(8):594–601

Socially deprived patients face significant barriers that reduce their access to care, presenting unique challenges for orthopaedic surgeons. Few studies have investigated the outcomes of surgical fracture care among those socially deprived, despite the increased incidence of fractures, and the inequality of care received in this group. The purpose of this study was to evaluate whether social deprivation impacted the complications and subsequent management of marginalized/homeless patients following ankle fracture surgery.

In this retrospective, population-based cohort study involving 202 hospitals in Ontario, Canada, we evaluated 45,444 patients who underwent open reduction internal fixation for an ankle fracture performed by 710 different surgeons between January 1, 1994, and December 31, 2011. Socioeconomic deprivation was measured for each patient according to their residential location by using the “deprivation” component of the Ontario Marginalization Index (ON-MARG). Multivariable logistic regression models were used to assess the relationship between deprivation and shorter-term outcomes within 1 year (implant removal, repeat ORIF, irrigation and debridement due to infection, and amputation). Multivariable cox proportional hazards (CPH) models were used to assess longer-term outcomes up to 20 years (ankle fusion and ankle arthroplasty).

A higher level of deprivation was associated with an increased risk of I&D (quintile 5 vs. quintile 1: odds ratio (OR) 2.14, 95% confidence interval (CI), 1.25–3.67, p = 0.0054) and amputation (quintile 4 vs. quintile 1: OR 3.56, 95% CI 1.01–12.4, p = 0.0466). It was more common for less deprived patients to have their hardware removed compared to more deprived patients (quintile 5 vs. quintile 1: OR 0.822, 95% CI 0.76–0.888, p < 0.0001). There was no correlation between marginalization and subsequent revision ORIF, ankle fusion, or ankle arthroplasty.

Marginalized patients are at a significantly increased risk of infection and amputation following operatively treated ankle fractures. However, these complications are still extremely rare among this group. Thus, socioeconomic deprivation should not prohibit marginalized patients from receiving operative management for unstable ankle fractures.

Introduction. Despite costing up to 5X more than a one-third tubular plate (TTP) and no absolute indications, distal fibula locking plates (DFLP) are becoming increasingly popular in the fixation of ankle fractures, particularly in the elderly. We reviewed all our distal fibula fracture fixations, over the course of one year, in order to rationalise DFLP use. Methods. Patient demographics, Weber classification, use of DFLP or TTP and the mode of fixation were recorded. Open fractures and tibial plafond fractures were excluded. Results. 51/84 (61%) of patients had DFLP fixation of their distal fibula fracture, the majority (44/51) of which were for Weber B fractures. The DFLP was used in bridge mode for 12 Weber B fractures and in neutralisation mode for remaining 32. There was a significant difference in age between the DFLP and TTP groups for all fractures (p< 0.005) and for Weber B fractures treated in bridge mode (p=0.036), but not for Weber B fractures treated with a lag screw/ neutralisation plate (p=0.09). Discussion. In 32/44 of our cases, we used the DFLP to neutralise a lag screw. However DFLP are only of mechanical benefit when adequate fracture compression is not obtained either due to fracture comminution or due to osteoperotic bone, often seen in the elderly. All 32 of these Weber B fractures were amenable to a lag screw and were not comminuted. There was also no significant age difference between this group and the group of Weber B fractures that were treated with a lag screw/ neutralisation plate. In these cases therefore, the DFLP did not offer any mechanical advantage. Conclusion. We propose limiting the use of the DFLP to fibula fractures where intra-fragmentary compression cannot adequately be obtained, thus reducing our use by over 60% and significantly reducing our implant costs for such injuries

Introduction

The primary goal of treatment of an ankle fracture is to obtain a stable anatomic fixation to facilitate early mobilisation and good functional recovery. However, the need for open reduction and internal fixation must be weighed against poor bone quality, compromised soft tissues, patient co-morbidities and potential wound-healing complications.

Ankle fractures are common injuries and commonly require operative stabilisation. The aim of treatment should be anatomical reduction as this will lead to good long-term results. Non-anatomically reduced fractures will lead to a poor functional outcome and development of osteoarthritis. Our aim was to determine whether revision of non-anatomical fixations within 12 months of initial surgery improved outcome.

We present eight cases of non-anatomical ankle fixations that were revised by the senior author over a 4-year period. There were 4 females and 4 males. The mean age was 45.6 years at review (range 28–63) and the mean time from initial fixation to revision was 5.25 months (range 2–11). Mean time at review was 26.6 months (range 7–45). Clinical scoring for functional outcome was performed using the American Orthopaedic Foot and Ankle Society (AOFAS) rating system for the ankle and hindfoot. Mean AOFAS score prior to revision was 40 (range 19–69) and the mean score at review was 80 (range 54–100).

All patients reported benefit in terms of function from the revision procedure. The aim of initial surgery is for anatomical reduction of the ankle joint. Should suboptimal fixation be encountered within 12 months of the initial surgery, we feel revision surgery is justified.

Introduction

The aim of this study was to compare the results and length of stay of patients of early (within 12 hours) versus conventional (after 48 hours) ankle fixation our hospital.
