The posterior malleolus component of a fracture of the ankle is important, yet often overlooked. Pre-operative CT scans to identify and classify the pattern of the fracture are not used enough. Posterior malleolus fractures are not difficult to fix. After reduction and fixation of the posterior malleolus, the articular surface of the tibia is restored; the fibula is out to length; the syndesmosis is more stable and the patient can rehabilitate faster. There is therefore considerable merit in fixing most posterior malleolus fractures. An early post-operative CT scan to ensure that accurate reduction has been achieved should also be considered.

A number of classification systems exist for posterior malleolus fractures of the ankle. The reliability of these classification systems remains unclear. The primary aim of this study was to evaluate the reliability of three commonly utilised fracture classification systems of the posterior malleolus. 60 patients across 2 hospitals sustaining an unstable ankle fracture with a posterior malleolus fragment were identified. All patients underwent radiographs and computed tomography of their injured ankle. 9 surgeons including pre-ST3 level, ST3-8 level, and consultant level applied the Haraguchi, Rammelt, and Mason & Molloy classifications to these patients, at two timepoints, at least 4 weeks apart. The order was randomised between assessments. Inter-rater reliability was assessed using Fleiss’ kappa and 95% confidence intervals (CI). Intra-rater reliability was assessed using Cohen's Kappa and standard error (SE). Inter-rater reliability (Fleiss’ Kappa) was calculated for the Haraguchi classification as 0.522 (95% CI 0.490 – 0.553), for the Rammelt classification as 0.626 (95% CI 0.600 – 0.652), and the Mason & Molloy classification as 0.541 (95% CI 0.514 – 0.569). Intra-rater reliability (Cohen's Kappa) was 0.764 (SE 0.034) for the Haraguchi, 0.763 (SE 0.031) for the Rammelt, 0.688 (SE 0.035) for the Mason & Molloy classification. This study reports the inter-rater and intra-rater reliability for three classification systems for posterior malleolus fractures. Based on definitions by Landis & Koch (1977), inter-rater reliability was rated as ‘moderate’ for the Haraguchi and Mason & Molloy classifications; and ‘substantial’ for the Rammelt classification. Similarly, the intra-rater reliability was rated as ‘substantial’ for all three classifications

Introduction. Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Studies have demonstrated a high proportion have ipsilateral occult posterior malleolus fractures. We hypothesize that this rotational element will be highlighted using the Mason & Molloy Classification. Materials and Methods. A retrospective review of a prospectively collected database was performed at Liverpool University Hospitals NHS Foundation Trust between 1/1/2013 and 9/11/2020. The inclusion criteria were patients over 16, with a diaphyseal tibial fracture, who underwent a CT. The Mason and Molloy posterior malleolus fracture classification system was used. Results. 764 diaphyseal tibial fractures were analysed, 300 had a CT. 127 were intra-articular fractures. 83 (27.7%) were classifiable using Mason and Molloy classification. There were 8 type 1 (9.6%), 43 type 2 (51.8%), 5 type 2B (6.0%) and 27 type 3 (32.5%). 90.4% (n=75) of the posterior malleolar fractures, were undisplaced. The majority of PM fractures occurred in type 42A1 (65 of 142 tibia fractures) and 42B1 (11 of 16). Conclusions. Most PM fractures occurred after a rotational mechanism. Unlike, the PM fractures of the ankle, the majority of PM fractures associated with tibia fractures are undisplaced. We theorise that unlike the force transmission in ankle fractures where the rotational force is in the axial plane in a distal-proximal direction, in the PM fractures related to fractures of the tibia, the rotational force in the axial plane progresses from proximal-distal. Therefore, the force transmission which exits posteriorly, finally dissipates the force and thus unlikely to displace

The aim of this study was to evaluate the long-term outcomes of patients who had sustained an unstable ankle fracture with a posterior malleolus fracture (PMF) and without (N-PMF). Adult patients presenting to a single academic trauma centre in Edinburgh, UK, between 2009 and 2012 with an unstable ankle fracture requiring surgery were identified. The primary outcome measure was the Olerud Molander Ankle Score (OMAS). Secondary measures included Euroqol-5D-3L Index (Eq5D3L), Euroqol-5D-VAS and Manchester Oxford Foot Questionnaire (MOXFQ). There were 304 patients in the study cohort. The mean age was 49.6 years (16.3–78.3) and 33% (n=100) male and 67% (n=204) female. Of these, 67% (n=204) had a PMF and 33% did not (n=100). No patient received a computed tomography (CT) scan pre-operatively. Only 10% of PMFs (22/204) were managed with internal fixation. At a mean of 13.8 years (11.3 – 15.3) the median OMAS score was 85 (Interquartile Range 60 – 100). There was no difference in OMAS between the N-PMF and PMF groups (85 [56.25 – 100] vs 85 [61.25 – 100]; p = 0.580). There was also no difference for MOXFQ (N-PMF 7 [0 – 36.75] vs PMF 8 [0–38.75]; p = 0.643), the EQ5D Index (N-PMF 0.8 [0.7 – 1] vs PMF 0.8 [0.7 – 1]; p = 0.720) and EQ5D VAS (N-PMF 80 [70 – 90] vs PMF 80 [60 – 90]; p = 0.224). The presence of a PMF does not affect the long-term patient reported outcomes in patients with a surgically managed unstable ankle fracture

Introduction. Early clinical examination combined with MRI following a high ankle sprain allows accurate diagnosis of syndesmosis instability. However, patients often present late, and for chronic injuries clinical assessment is less reliable. Furthermore, in many centres MRI may be not be readily available. The aims of the current study were to define MRI characteristics associated with syndesmosis instability, and to determine whether MRI patterns differed according to time from injury. Methods. Retrospectively, patients with an unstable ligamentous syndesmosis injury requiring fixation were identified from the logbooks of two fellowship trained foot and ankle surgeons over a five-year period. After exclusion criteria (fibula fracture or absence of an MRI report by a consultant radiologist), 164 patients (mean age 30.7) were available. Associations between MRI characteristics and time to MRI were examined using Pearson's chi-square tests or Fisher's exact tests (significance set at p< 0.05). Results. Overall, 100% of scans detected a syndesmosis injury if performed acutely (within 6 weeks of injury), falling to 83% if performed after 12 weeks (p=0.001). In the acute group, 93.5% of patients had evidence of at least one of either PITFL injury (78.7%), posterior malleolus bone oedema (60.2%), or a posterior malleolus fracture (15.7%). In 20% of patients with a posterior malleolus bone bruise or fracture, the PITFL was reported as normal. The incidence of posterior malleolus bone bruising and fracture did not significantly differ according to time. Conclusion. For unstable ligamentous syndesmosis injuries, MRI becomes less sensitive over time. Importantly, posterior malleolus bone oedema or fracture may be the only evidence of a posterior injury. Failure to recognise instability may lead to inappropriate management of the patient, long term pain and arthritis. We therefore advocate early MRI as it becomes more difficult to ‘grade’ the injury if delayed

Introduction. Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Several studies demonstrate a high proportion of diaphyseal tibial fractures have ipsilateral occult posterior malleolus fractures, this ranges from 22–92.3%. Materials and Methods. A retrospective review of a prospectively collected database was performed at Liverpool University Hospitals NHS Foundation Trust between 1/1/2013 and 9/11/2020. The inclusion criteria were patients over 16, with a diaphyseal tibial fracture and who underwent a CT. The articular fracture extension was categorised into either posterior malleolar (PM) or other fracture. Results. 764 fractures were analysed, 300 had a CT. There were 127 intra-articular fractures. 83 (65.4%) cases were PM and 44 were other fractures. On univariate analysis for PM fractures, fibular spiral (p=.016) fractures, no fibular fracture(p=.003), lateral direction of the tibial fracture (p=.04), female gender (p=.002), AO 42B1 (p=.033) and an increasing angle of tibial fracture. On multivariate regression analysis a high angle of tibia fracture was significant. Other fracture extensions were associated with no fibular fracture (p=.002), medial direction of tibia fracture (p=.004), female gender (p=.000), and AO 42A1 (p=.004), 42A2 (p=.029), 42B3 (p=.035) and 42C2 (p=.032). On multivariate analysis, the lateral direction of tibia fracture, and AO classification 42A1 and 42A2 were significant. Conclusions. Articular extension happened in 42.3%. A number of factors were associated with the extension, however multivariate analysis did not create a suitable prediction model. Nevertheless, rotational tibia fractures with a high angle of fracture should have further investigation with a CT

Management of complex posterior malleolar fractures requires a detailed appreciation of ligamentous and bony anatomy for optimal fracture fixation and restoration of articular congruency. Pre operative planning is vitally important to determine the surgical strategy for complex ankle fractures. We evaluated pre operative planning strategy pre and post implementation of BOAST 12 guidelines (2016) focussing on pre operative CT scans prior to definitive fixation at a major trauma centre. A multi-surgeon retrospective review of prospectively collected data from 2013 to 2018 was performed at a major trauma centre. Patients who had sustained a posterior malleolar fracture and definitive fixation were identified. Information was collated from PICS, PACS, the trauma database and operative notes. 134 patients were identified over a 5 year period who had sustained a posterior malleolar fracture and had definitive fixation. (Pre BOAST guidelines = 61, Post BOAST guidelines = 73). Prior to the implementation of BOAST guidelines ¼ with posterior malleolar fractures did not have a pre operative CT scan (15/61). Post implementation of BOAST 12 90% (66/73)patients with fixation of posterior malleolus fractures had a pre operative CT scan. Posterior malleolus surgery most commonly took place In patients between 18–30 years. Following implantation of BOAST 12 guidelines there was a 15% increase in pre operative CT scanning for ‘complex ankle fractures'. Changes in national guidelines have heavily influenced pre operative planning strategy for ankle fractures at University Hospitals Birmingham. A detailed appreciation of fracture pattern pre operatively helps guide surgical strategy

The optimal management of rotationally-unstable ankle fractures involving the posterior malleolus remains controversial. Standard practice involves trans-syndesmotic fixation (TSF), however, recent attention has been paid to the indirect reduction of the syndesmosis by repairing small posterior malleolar fracture avulsion fragments, if present, using open reduction internal fixation. Posterior malleolus fixation (PMF) may obviate the need for TSF. Given the limited evidence and diversity in surgical treatment options for rotationally-unstable ankle fractures with ankle syndesmosis and posterior malleolar involvement, we sought to assess the research landscape and identify knowledge gaps to address with future clinical trials. We performed a scoping review to investigate rotational ankle fractures with posterior malleolar involvement, utilizing the framework originally described by Arksey and O'Malley. We searched the English language literature using the Ovid Medline and Embase databases. All study types investigating rotationally-unstable ankle fractures with posterior malleolus involvement were categorized into defined themes and descriptive statistics were used to summarize methods and results of each study. A total of 279 articles published from 1988 to 2018 were reviewed, and 70 articles were included in the final analysis. The literature consists of studies examining the surgical treatment strategies for PMF (n=21 studies, 30%), prognosis of rotational ankle fractures with posterior malleolar involvement (n=16 studies, 23%), biomechanics and fracture pattern of these injuries (n=13 studies, 19%), surgical approach and pertinent anatomy for fixation of posterior malleolus fractures (n=12 studies, 17%), and lastly surgical treatment of syndesmotic injuries with PMF compared to TSF (n=4 studies, 6%). Uncontrolled case series of single treatment made up the majority of all clinical studies (n=44 studies, 63%), whereas controlled study designs were the next most common (n=16 studies, 23%). Majority of research in this field has been conducted in the past eight years (n=52 studies, 74%). Despite increasing concern and debate among the global orthopaedic community regarding rotationally-unstable ankle fractures with syndesmosis and posterior malleolar involvement, and an increasing trend towards PMF, optimal treatment remains unclear when comparing TSF to PMF. Current research priorities are to (1) define the specific injury pattern for which PMF adequately stabilizes the syndesmosis, and (2) conduct a randomized clinical trial comparing PMF to TSF with the assistance of the orthopaedic community at large with well-defined clinical outcomes

Purpose. The aim of this prospective study was to determine the usefulness of a gravity stress view in detecting instability in isolated Weber B fractures of the fibula. Materials and methods. We used a standard protocol for patient selection, exclusion, surgery/conservative management and follow-up. Open fractures, fracture dislocations, those with medial/posterior malleolus fractures and those with preliminary X-rays showing a talar shift/tilt were excluded. If the medial clear space increased beyond 4mm on stress radiographs, surgical reduction and fixation of the lateral malleolus was performed. If this remained 4mm or less conservative treatment was undertaken. We followed these patients at 2, 4, 6 and 12 weekly intervals. Results. We recruited 18 patients with isolated Weber B fractures. In 7 patients the medial clear space increased from 4mm to an average of 6.29 mm (Range 5-7mm). 6 of these 7 patients were operated. The medial clear space remained 4mm or less in the remaining 11 patients and were therefore managed conservatively. No complications were noted in either the surgical or the non-surgical group. None of the conservatively managed fractures showed radiological features of instability on follow up. All the 17 patients who were followed up in our hospital had excellent final AOFAS Scores. Conclusion. We conclude that gravity stress views are useful in determining the stability of Weber B fractures of the ankle

Aim: To assess whether stable undisplaced ankle fractures treated conservatively with a below knee non weight bearing cast ever displace. Methods: Retrospective case notes analysis was performed. Between August 2007 and August 2009, one hundred and twenty one patients sustained a stable undisplaced ankle fracture which was treated conservatively. Their age range was from 16 to 86 years. Male to female ratio was 74:47. The mean number of clinic follow ups was 3.7. These patients were classified according to the Danis-Weber Classification for analysis. Thirty (25%) patients had Weber A1 fractures, seventy two (60%) had Weber B1 fractures, five patients (4%) had Weber B2 fractures, three patients (2%) had Weber C1 fractures, ten patients (8%) had isolated medial malleolus fracture and one patient suffered an isolated posterior malleolus fracture. Results: An average of 4.7 x-rays were performed on each patient from the time of diagnosis to discharge from clinic. None of these fractures displaced on follow up x-rays. Conclusion: Stable undisplaced ankle fractures treated conservatively with a below knee non weight bearing cast do not displace. Hence these patients do not require to be followed up frequently with serial x-rays as they may be exposed to unnecessary harmful radiation and follow up appointments thereby saving time, money and resources

Background. Tightrope fixation has been suggested as an alternative to screw stabilisation for distal tibiofibular joint diastasis that provides stability but avoids the problems of rigid screws across the joint. Recent case series (of 6 and 16 patients) have however, reported soft tissue problems and infections in 19–33% of patients. This study aims to review treatment and complications of distal tibiofibular diastasis fixation in our unit with the use of Tightrope or diastasis screws. Methods. Retrospective review of all patients undergoing primary ankle fixation between May 2008 and October 2009. Exclusions included revision procedures, or ankle fixation prior to the current fracture. Those undergoing Tightrope or diastasis screw fixation were studied for any complications or further procedures. Clinical records and XRAYs were reviewed, family practitioners of the patients were contacted and any consultations for ankle related problems noted. Results. 187 primary ankle fixation procedures were performed. 35 ankles required stabilisation of the distal tibiofibular joint. In 12, this was achieved using the Tightrope and in 23, syndesmotic screws were used. There was no difference in the adequacy of reduction in the two groups. Of those stabilised with a Tightrope, 6 were Maisonneuve injuries, 5 Weber C and 1 Weber B. 1 was lost to followup. Of the remaining 11, none had complications attributable to the method of fixation documented in hospital or family practitioner records. One had a small stitch abscess that settled on removal of the suture material. None underwent subsequent procedures. Of 23 stabilised with screws, 4 were Weber B, 14 Weber C, 4 Maisonneuve and 1 syndesmotic injury associated with an isolated posterior malleolus fracture. In this group of patients with primary ankle fixation involving a diastasis screw there was 1 deep infection requiring removal of metalwork, 1 superficial wound infection after syndesmotic screw removal and 1 wound breakdown after syndesmotic screw removal. A patient developed superficial peroneal nerve palsy at operation and 1 syndesmotic fixation failed and underwent revision surgery. This patient subsequently developed infection and had revision to a hindfoot nail. 19 patients underwent screw removal. The 23 patients underwent 45 procedures (mean 1.96 procedures per patient). Conclusion. In a consecutive series of 187 ankle procedures, 12 had the distal tibiofibular joint stabilised with a Tightrope with no noted complications attributable to the implant and no additional procedures. 23 patients underwent diastasis screw fixation with 19 screw removal procedures and 5 complications of various severity, 2 of which were attributable to screw removal. Tightrope fixation has provided stable fixation of the injured syndesmosis in our unit and we have not to date encountered complications previously described in the literature

Aims

Paediatric triplane fractures and adult trimalleolar ankle fractures both arise from a supination external rotation injury. By relating the experience of adult to paediatric fractures, clarification has been sought on the sequence of injury, ligament involvement, and fracture pattern of triplane fractures. This study explores the similarities between triplane and trimalleolar fractures for each stage of the Lauge-Hansen classification, with the aim of aiding reduction and fixation techniques.

Methods

Imaging data of 83 paediatric patients with triplane fractures and 100 adult patients with trimalleolar fractures were collected, and their fracture morphology was compared using fracture maps. Visual fracture maps were assessed, classified, and compared with each other, to establish the progression of injury according to the Lauge-Hansen classification.

Aims

Ankle fracture is one of the most common musculoskeletal injuries sustained in the UK. Many patients experience pain and physical impairment, with the consequences of the fracture and its management lasting for several months or even years. The broad aim of ankle fracture treatment is to maintain the alignment of the joint while the fracture heals, and to reduce the risks of problems, such as stiffness. More severe injuries to the ankle are routinely treated surgically. However, even with advances in surgery, there remains a risk of complications; for patients experiencing these, the associated loss of function and quality of life (Qol) is considerable. Non-surgical treatment is an alternative to surgery and involves applying a cast carefully shaped to the patient’s ankle to correct and maintain alignment of the joint with the key benefit being a reduction in the frequency of common complications of surgery. The main potential risk of non-surgical treatment is a loss of alignment with a consequent reduction in ankle function. This study aims to determine whether ankle function, four months after treatment, in patients with unstable ankle fractures treated with close contact casting is not worse than in those treated with surgical intervention, which is the current standard of care.

Methods

This trial is a pragmatic, multicentre, randomized non-inferiority clinical trial with an embedded pilot, and with 12 months clinical follow-up and parallel economic analysis. A surveillance study using routinely collected data will be performed annually to five years post-treatment. Adult patients, aged 60 years and younger, with unstable ankle fractures will be identified in daily trauma meetings and fracture clinics and approached for recruitment prior to their treatment. Treatments will be performed in trauma units across the UK by a wide range of surgeons. Details of the surgical treatment, including how the operation is done, implant choice, and the recovery programme afterwards, will be at the discretion of the treating surgeon. The non-surgical treatment will be close-contact casting performed under anaesthetic, a technique which has gained in popularity since the publication of the Ankle Injury Management (AIM) trial. In all, 890 participants (445 per group) will be randomly allocated to surgical or non-surgical treatment. Data regarding ankle function, QoL, complications, and healthcare-related costs will be collected at eight weeks, four and 12 months, and then annually for five years following treatment. The primary outcome measure is patient-reported ankle function at four months from treatment.

Aims. Involvement of the posterior malleolus in fractures of the ankle probably adversely affects the functional outcome and may be associated with the development of post-traumatic osteoarthritis. Anatomical reduction is a predictor of a successful outcome. The purpose of this study was to describe the technique and short-term outcome of patients with trimalleolar fractures, who were treated surgically using a posterolateral approach in our hospital between 2010 and 2014. Patients and Methods. The study involved 52 patients. Their mean age was 49 years (22 to 79). There were 41 (79%) AO 44B-type and 11 (21%) 44C-type fractures. The mean size of the posterior fragment was 27% (10% to 52%) of the tibiotalar joint surface. Results. Reduction was anatomical in all patients with a residual step in the articular surface of ≤ 1 mm. In nine of the C-type fractures (82%), the syndesmosis was stable after fixation of the posterior fragment and a syndesmosis screw was not required. Apart from one superficial wound infection, there were no wound healing problems. At a mean radiological follow-up of 34 weeks (seven to 131), one patient with a 44C-type fracture had widening of the syndesmosis which required further surgery. Conclusion. We conclude that the posterolateral surgical approach to the ankle gives adequate access to the posterior malleolus, allowing its anatomical reduction and stable fixation: it has few complications. Take home message: Fixation of the posterior malleolus in trimalleolar fractures can be easily done via the posterolateral approach whereby anatomical reduction and stable fixation can be reached due to adequate visualisation of the fracture.

Aims

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

Methods

Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)).

Ankle fractures are among the most common injuries treated by orthopaedic surgeons, and surgical treatment is often required to optimise the results. This retrospective study was undertaken to assess the effectiveness of the TRIMED ankle fixation system in the treatment of malleolar fractures. During the last ten months, fifteen patients with an average age of 63 years underwent open reduction and internal fixation of a bimalleolar ankle fracture with the TRIMED fixation system. A standart surgical approach was used for both the medial and lateral malleolus. Regarding the lateral malleolus, a TRIMED Sidewinter plate which requires no additional interfragmentary screw was applied. Based on the morphology of the fracture of the medial malleolus, either interfragmentary screws or the sled- like medial malleolus fixation system was applied. One patient underwent in addition open reduction and internal fixation of the posterior malleolus. All fractures proceeded to uncomplicated union in an average healing time of 6 weeks. Excellent functional restoration of the ankle joint, comparable to the ipsilateral ankle, was achieved. The TRIMED ankle fixation system represents a good alternative method in malleolar fracture fixation which simplifies the fracture reduction and obliterates the need for a lag screw, thus preserving the biology of the fracture site. Furthermore, it can be used for the reconstruction of distal fractures of the lateral malleolus. However, further long-term studies are recommended to evaluate the success of the TRIMED fixation system

Purpose: Lower extremity articular fracture treatment requires acccurate diagnosis and anatomic reduction and fixation. As articular injuries, posterior malleolus (PM) fractures are still poorly defined: for example the incidence of associated PM marginal impaction and of free articular fragments is unknown. The purposes of this study were:. to define the articular injuries of PM fractures into clincially relevant groups, as complex articular injuries could require specific surgical steps;. to identify clinical and radiographic parameters which would alert the surgeon to the presence of complex injuries. Method: Our prospectively-collected orthopaedic trauma database (OTDB) query identified 796 ankle fractures treated operatively between 2003–2007. Of these 147 cases involved the posterior malleolus. Four were misclassified leaving 143 cases. We obtained demographic and injury data from the OTDB, and validated the OTDB coded mechanisms of injury by an individual chart review. We reviewed all radiographs to describe the PM injuries (fracture patterns and dimensions) and to identify the associated injuries. Results: Of the 143 cases: Mean age was 50 years (sd=19), 68.5% were female, 51% were right sided injuries, and the median ISS=4 (in fact, 97.5% had ISS=4, most therefore being isolated trauma). The mean post malleolus AP size=11mm (sd=5). We identified recurrent patterns and classified the PM fracture as SIMPLE or COMPLEX (to include marginal impaction or free comminuted fragment, which should be anatomically reduced), 42% of cases (60/143) were COMPLEX (18 were impaction, 42 were free fragment). To help clinicians identify which cases could be COMPLEX we correlated (Chi-sq) the presence of a COMPLEX PM fracture to common clinical and radiographic variables. COMPLEX PM were statistically significantly associated with (p values). an axial loading injury mechanism (.000),. a radiographically captured dislocation (.006),. posteromedial comminution [as defined Tor-netta] (.005). the size of the fragment (.000). For example, axial loading would result in a complex fracture in > 85% of cases. In contrast, there was a statistically significant association between a Weber C fracture and older age and the presence of a SIMPLE PM fracture. These factors being potentially “protective” from joint comminution. Conclusion: We have defined and quantified the PM articular lesions which require anatomic reduction and fixation, beyond what has been published. We have defined clinical and radiographic criteria which, because higly associated with COMPLEX lesions, could. prompt surgeons to order further imaging (CT) to better delineate the lesion, and. draw his/her attention to potentially malaligned fragments at the time surgery
