Abstract
Foot and ankle surgeons are commonly confronted with the surgical dilemma on when and how to best surgically address trimalleolar ankle fractures with a posterior malleolar component. This may involve either direct fixation of the posterior malleolus or indirect stabilization with the fixation of the medial and lateral malleoli and trans-syndesmotic fixation. Recently there has been a paradigm shift in the management of these injuries with a more thorough understanding of anatomy, stability, and long-term sequela of these injuries. This article aims to evaluate the current literature on posterior malleolar ankle fractures, approaches to fixing the posterior malleolus, and outcomes and complications of these procedures.

Abstract
INTRODUCTION Trimalleolar fractures are difficult to treat and malreduction can lead to functional impairment. Involvement of the posterior malleolus has a poor predictive value. Current computed-tomography (CT)-based fracture classifications led to an increase in fixation of the posterior malleolus. The aim of this study was to describe the functional outcome after a two-stage stabilisation with direct fixation of the posterior fragment in trimalleolar dislocation fractures. MATERIALS AND METHODS In a retrospective study, all patients presenting with a trimalleolar dislocation fracture, an available CT scan, and a two-stage operative stabilisation including the posterior malleolus by a posterior approach were included. All fractures were treated with initial external fixator and delayed definitive stabilisation including fixation of the posterior malleolus. Next to clinical and radiological follow-up, outcome measures (Foot and Ankle Outcome Score (FAOS), Numeric Rating Scale (NRS), Activity of Daily Living (ADL), Hulsmans implant removal score) and complications were analysed. RESULTS Between 2008 and 2019, of 320 trimalleolar dislocation fractures, 39 patients were included. Mean follow-up was 49 months (standard deviation (SD) 29.7, range 16-148). Mean age was 60 years (SD 15.3, 17-84) with 69% female patients. The mean FAOS was 93/100 (SD 9.7, 57-100), NRS 2 (interquartile range (IQR) 0-3) and ADL 2 (IQR 1-2). Four patients showed a postoperative infection, three re-operations had to be performed and implants were removed in 24 individuals. CONCLUSION A two-stage procedure of trimalleolar dislocation fractures with in-direct reduction and fixation of the posterior tibial fragment through a posterior approach leads to good functional outcome scores with a low rate of complications.

Abstract
INTRODUCTION Complex ankle fractures frequently involve the posterior malleolus. Many classifications describing posterior malleolar fractures (PMF) exist. The aim of this study was to provide a systematic literature review to outline existing PMF classifications and estimate their accuracy. METHODS The databases PubMed and Scopus were searched without time limits. Only specific PMF classifications were included; general ankle and/or pilon fracture classifications were excluded. Selection and data extraction was performed by three independent observers. The systematic literature search was performed according to the current criteria of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The methodological quality of the included studies was quantified using the modified Coleman score. RESULTS A total of 110 studies with a total of 12.614 patients were included. Four main classifications were identified: Those describing the size of the posterior malleolar fracture (n = 66), Haraguchi (n = 44), Bartoníček/Rammelt (n = 21) and Mason (n = 12). The quality of the studies was moderate to good with a median Coleman-score of 43.5 (14-79) and a weighted median Coleman-score of 42.5 points. All classifications achieved a substantial to perfect score regarding the inter- and intraobserver reliability, with Mason scoring the lowest in comparison. CONCLUSIONS None of the reviewed PMF classifications has been able to establish itself decisively in the literature. Most of the classifications are insufficient in terms of a derivable treatment algorithm or a prognosis with regard to outcome. However, as the Bartoníček/Rammelt classification has the greatest potential due to its treatment algorithm, its reliability in combination with consistent predictive values, its usage in clinical practice and research appears advisable.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1152. [PMID: 37374356 DOI: 10.3390/medicina59061152] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/24/2023] [Accepted: 05/25/2023] [Indexed: 06/29/2023]
Abstract
Background and Objective: This meta-analysis was performed to compare the effectiveness of surgical treatment and conservative treatment in adult ankle fractures. Methods: Pubmed, Embase, and Cochrane-Library databases were searched to retrieve prospective randomized-controlled studies that compared the efficacy of surgical treatment and conservative treatment in adult ankle fractures. The meta package in R language was used to organize and analyze the obtained data. Results: A total of eight studies involving 2081 patients was considered eligible, including 1029 patients receiving surgical treatment and 1052 receiving conservative treatment. This systematic review and meta-analysis was prospectively registered on PROSPERO, and the registration number is CRD42018520164. Olerud and Molander ankle-fracture scores (OMAS) and the health survey 12-item Short-Form (SF-12) were used as main outcome indicators, and the follow-up outcomes were grouped according to the follow-up time. Meta-analysis results showed significantly higher OMAS scores in patients receiving surgical treatment than those with conservative treatment at six months (MD = 1.50, 95% CI: 1.07; 1.93) and over 24 months (MD = 3.10, 95% CI: 2.46; 3.74), while this statistical significance was absent at 12-24 months (MD = 0.08, 95% CI: -5.80; 5.96). At six months and 12 months after treatment, patients receiving surgical treatment exhibited significantly higher SF12-physical results than those receiving conservative treatment (MD = 2.40, 95% CI: 1.89; 2.91). The MD of SF12-mental data at six months after meta-analysis was -0.81 (95% CI: -1.22; 0.39), and the MD of SF12-mental data at 12+ months was -0.81 (95% CI: -1.22; 0.39). There was no significant difference in SF12-mental results between the two treatment methods after six months, but after 12 months, the SF12-mental results of patients receiving surgical treatment were significantly lower than those of conservative treatment. Conclusions: In the treatment of adult ankle fractures, surgical treatment is more efficacious than conservative treatment in improving early and long-term joint function and physical health of patients, but it is associated with long-term adverse mental health.

Abstract
PURPOSE This study aimed to assess the impact of fixation on functional and radiological outcomes of ankle fractures involving the posterior malleolus. We hypothesized that fixation of the posterior malleolus would be associated with improved radiological and functional outcome. METHODS A prospective randomized controlled study was planned and 40 consecutive ankle fractures involving middle-sized (10-25%) posterior fragment were included. Posterior fragments in Group 1 were not fixated while Group 2 underwent posterior malleolus fixation. The patients were evaluated both functionally and radiologically at minimum 2-years. RESULTS Demographics and fracture type distributions were similar between the groups. Despite the slightly better functional outcome in Group 2, no significant functional or radiological outcome difference could be detected. Articular step-off> 1 mm was more common in Group 1 (p = 0.04) and the patients with articular step-off showed significantly worse functional outcome in all functional parameters (p < 0.05). Radiological and functional outcome parameters were positively correlated when all patients were evaluated together. Lateral radiographs caused an overestimation in the size of posterior fragment compared to CT (p < 0.001). CONCLUSION Although there was a slightly better clinical outcome in patients with fixed posterior fragments, it was not significant at short to mid-term follow-up. However, posterior fragment fixation contributed to functional outcomes by decreasing the incidence of articular step-off> 1 mm, which was found to be a negative prognostic factor.

Abstract
BACKGROUND The treatment of posterior malleolar fractures (PMFs) is debated, including the need for surgery and method of fixation. Recent literature has suggested that fracture pattern, rather than fragment size, may be an important predictor for ankle biomechanics and functional outcome. Biomechanical studies have been conducted to provide evidence-based treatment on the effects of fracture and fixation on contact pressure and stability. The objective of this scoping review is to summarize the methodologies used in biomechanical studies on PMFs and assess whether they are sufficient to test the need for surgery and method of fixation. METHODS A scoping review of publications before January 2022 was performed. PubMed/Medline and Embase Ovid were searched for cadaver or finite element analysis (FEA) studies that created and tested the effects of PMFs in ankle fractures. Both cadaver and FEA studies were included. Data about fragment characteristics, mode of testing, and outcomes were charted by 2 persons from the study group. The data were synthesized when possible and compared. RESULTS We included 25 biomechanical studies, including 19 cadaver studies, 5 FEA studies, and 1 cadaver and FEA study. Aside from the fragment size, few other fragment characteristics were reported. Mode of testing varied with different loads and foot positions. Strong conclusions on the effects of fracture and fixation on contact pressure and stability could not be made. CONCLUSION Biomechanical studies on PMFs demonstrate wide variability in fragment characteristics and mode of testing, which makes it difficult to compare studies and draw conclusions on the need for surgery and method of fixation. Additionally, limited reporting of fragment measurements questions the applicability to clinical practice. The biomechanical literature on PMFs would benefit from the use of a standard classification and universal fragment measurements to match clinical injuries in future biomechanical studies. Based on this review, we recommend the Mason classification, which addresses the pathomechanism, and use of the following fragment measurements in all 3 anatomic planes when creating and describing PMFs: fragment length ratio, axial angle, sagittal angle or fragment height, and interfragmentary angle. The testing protocol needs to reflect the purpose of the study. CLINICAL RELEVANCE This scoping review demonstrates wide methodological diversity of biomechanical studies. Consistency in methodology should enable comparison of study results, leading to stronger evidence-based recommendations to guide surgeons in decision making and offer PMF patients the best treatment.

Abstract
BACKGROUND Two of the most commonly used classifications for the posterior malleolus fracture are Haraguchi and Bartoníček. Both classifications are based on the morphology of the fracture. This study makes an inter- and intra-observer agreement analysis of the mentioned classifications. METHODS 39 patients with ankle fractures who met inclusion criteria were selected. All the fractures were analyzed and classified twice by each of the 20 observers using Bartoníček and Haraguchi's classifications, with a window period of at least 30 days between the two rounds. RESULTS Analysis was made by Kappa coefficient (ƙ). The global intraobserver value was ƙ = 0.627 in the Bartoníček classification and ƙ = 0.644 in the Haraguchi one. The first round global interobserver ƙ = 0.589 (0.574-0.604) on the Bartoníček classification and ƙ = 0.534 (0.517-0.551) on the Haraguchi one. Second round coefficients were ƙ = 0.601 (0.585-0.616) and ƙ = 0.536 (0.519-0.554), respectively. The best agreement was when there was involvement of the posteromedial malleolar zone with ƙ = 0.686 and ƙ = 0.687 in Haraguchi II and ƙ = 0.641 and ƙ = 0.719 in Bartoníček III. No differences were observed in Kappa values when an experience-based analysis was made. CONCLUSION Bartoníček and Haraguchi classifications of the posterior malleolus fracture have both substantial intraobserver agreement but moderate to substantial agreement in interobserver analysis.

Abstract
Background Ankle fractures involving the posterior malleolus (PM) tend to result in inferior clinical outcomes compared to other ankle fractures. However, it is unclear which specific risk factors and fracture characteristics are associated with negative outcomes in these fractures. The aim of this study was to identify risk factors for poor postoperative patient-reported outcomes in patients with fractures involving the PM. Methods This retrospective cohort study included patients who sustained ankle fractures involving the PM between March 2016 and July 2020 and had preoperative computed tomography (CT) scans. In total, 122 patients were included for analysis. One patient (0.8%) had an isolated PM fracture, 19 (15.6%) had bimalleolar ankle fractures involving the PM, and 102 (83.6%) had trimalleolar fractures. Fracture characteristics including the Lauge-Hansen (LH) and Haraguchi classifications and posterior malleolar fragment size were collected from preoperative CT scans. Patient Reported Outcome Measurement Information System (PROMIS) scores were collected preoperatively and at a minimum of 1 year postoperatively. The association between various demographic and fracture characteristics with postoperative PROMIS scores was assessed. Results Involvement of more malleoli was associated with worse PROMIS Physical Function (P = .04), Global Physical Health (P = .04), and Global Mental Health (P < .001), and Depression scores (P = .001). Elevated BMI was also associated with worse PROMIS Physical Function (P = .0025), Pain Interference (P = .0013), and Global Physical Health (P = .012) scores. Time to surgery, fragment size, Haraguchi classification, and LH classification were not associated with PROMIS scores. Conclusion In this cohort, we found that trimalleolar ankle fractures were associated with inferior PROMIS outcomes compared with bimalleolar ankle fractures involving the PM in multiple domains.

Abstract
BACKGROUND The treatment of posterior malleolar fractures is changing rapidly, and the evidence base is still catching up. This study aimed to assess the mid-term prognosis of posterior malleolar fractures based on different morphological types and provides evidence for the treatment of posterior malleolar fractures. METHODS We retrospectively analyzed the data of inpatients with posterior malleolar fractures from 1 January 2012 to 31 December 2019 at one high-volume tertiary trauma center. Fracture morphology was classified into small-shell fragment, single-fragment (small-fragment and large-fragment) and multifragment (double-fragment and compressive-fragment) by computed tomography according to our previous study. All patients were followed up at an average of 5.06 (range, 2.21-8.70) years. The Olerud-Molander Ankle Score (OMAS), EuroQol-5 Dimensions (EQ-5D) and American Orthopedic Foot and Ankle Society (AOFAS) score were recorded. RESULTS Seventy-nine patients were included, and 7 patients were classified into the small-shell group, 52 patients into the single-fragment group and 20 patients into the multifragment group. Of all the patients, the average OMAS, EQ-5D and AOFAS scores were 85.9, 82.8 and 92.5, respectively. In the single-fragment group, patients who underwent surgical fixation in the posterior malleolus had significantly better scores (P = 0.037, 0.033 and 0.027). Among the patients with small fragments, the surgical fixation group also had higher OMAS (93.1 ± 7.5 vs. 83.5 ± 19.5, P = 0.042) and AOFAS scores (98.1 ± 3.1 vs. 91.0 ± 14.1, P = 0.028). The mean OMAS, EQ-5D and AOFAS scores were 85.5, 85.7 and 91.7, respectively, in patients with multiple fragments who underwent surgical fixation. CONCLUSION This study shows that in fractures with a single fragment, surgical fixation of the posterior malleolar fragment led to a better prognosis in the midterm. All single fragments should be fixed regardless of size. Fixation of the posterior region in all single- and multi-fragments in posterior malleolar fractures led to satisfactory outcomes. LEVEL OF EVIDENCE Level III, follow-up study.

Abstract
INTRODUCTION An intra-articular impacted fragment (IAIF) could lead to articular incongruity and malreduction in ankle fractures with posterior malleolar fractures (PMFs). No studies have been conducted to determine whether the presence of IAIF affects the outcome of ankle fractures with PMF. The aim of our retrospective study was to evaluate the effect of IAIF on postoperative outcomes in PMF and analyze the relationship between area of IAIF and outcomes. MATERIALS AND METHODS We conducted a retrospective study of patients with a posterior malleolar fractures between June 2012 and January 2019 with a minimum follow-up of 2 years. Results of the Olerud-Molander ankle score (OMAS), EuroQol-5D (EQ-5D) index, EQ-5D visual analog scale (VAS), AOFAS (American orthopedic foot and ankle society ankle-hindfoot scale), visual analog scale (VAS) pain score and overall patient satisfaction scale were recorded. Outcomes of the PMF with IAIF group and PMF without IAIF group were compared. Sub-group analysis was given emphasis on the AIAIF > 40 mm2 group and AIAIF < 40 mm2 group in PMF with IAIF. RESULTS A total of 128 patients were included in the study, consisting of 86 patients with IAIF and 42 patients without IAIF. Regarding the osteoarthritis grade (> 1, ≤ 1), the differences werestatistically significant between the two groups (P = 0.044). The risk of articular malreduction was higher in the PMF with IAIF group than in the PMF without IAIF group (P = 0.035). Osteoarthritis grade (> 1, ≤ 1) was closely related to articular malreduction (P < 0.001). There were 51 patients in the AIAIF > 40 mm2 group and 35 patients in the AIAIF < 40 mm2 group of 86 patients in PMF with IAIF. There were statistically significant differences in trimalleolar fracture (P = 0.004), malreduction (P = 0.022), osteoarthritis grade (> 1, ≤ 1; P = 0.027), EQ-5D VAS score (P = 0.031), and AOFAS score (P = 0.047) between the subgroups. CONCLUSION The incidence of IAIF is associated with the area of the posterior malleolar fragment. Articular malreduction can lead to post-traumatic osteoarthritis, while IAIF is an important element for the quality of reduction, which is more likely to lead to articular malreduction. IAIF should be reduced if AIAIF is over 40 mm2. Otherwise, the patient will suffer a poor prognosis and post-traumatic osteoarthritis. Therefore, ankle fractures with PMF should undergo a CT scan preoperatively in order for providers to optimal treatment protocols. LEVEL OF EVIDENCE Level III.

Abstract
The evaluation and treatment of the posterior malleolus fracture in unstable ankle injuries remain a topic of controversy. The main objective of this systematic review was to examine the available literature and identify the variables that affect the management of posterior malleolar fractures and how these are related to the outcomes. To that end, a systematic review was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search of MEDLINE, Embase, and Cochrane Library was conducted. The search terms used were as follows: "posterior malleolar", "ankle fractures", "trimalleolar fractures", "ORIF", "surgery", "operative", and "conservative". The available studies were screened against the inclusion and exclusion criteria. Based on the review of the available literature, we have concluded that the size of the posterior malleolar fragment is not an accurate indicator, and clinicians should consider other factors such as fracture configuration and articular surface congruity. Also, the risk for the development of post-traumatic arthritis increases when the joint surface is not restored regardless of the surgical intervention and fragment size. The complications of posterior malleolus fractures necessitate evidence-based management. The assessment and the final treatment of these injuries in unstable ankle fractures should not be based on the traditional fragment-size parameters. Clinicians should assess the fracture configuration through imaging modalities and try to preserve the articular surface congruity so as to achieve optimal outcomes. Finally, more studies with high-level evidence are required in order to determine the most appropriate management pathway for these patients.

Influence of posterior malleolar fragment morphology on the outcomes of trimalleolar fractures: A systematic review and meta-analysis. Foot Ankle Surg 2022; 28:1337-1344. [PMID: 35810125 DOI: 10.1016/j.fas.2022.06.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 06/08/2022] [Accepted: 06/21/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Trimalleolar fractures are generally considered to have inferior outcomes among ankle injuries. Historically, emphasis was placed on the size of the posterior malleolar fracture (PMF) to guide surgical decision-making and predict outcomes. Recent studies have suggested that the morphology of the PMF fragment is more important than its size. The aim of this systematic review was to determine if the outcomes of trimalleolar fractures depend on the morphology of the PMF as per the Haraguchi classification system after surgical fixation. METHODS A systematic literature search was conducted in the electronic databases of PubMed, Embase, Scopus, and Ovid. Title and abstracts were screened, and data from eligible studies were extracted. Meta-regression and pooled analysis was performed using appropriate computer software. RESULTS 11 studies with 597 patients were included in the final analysis. Pooled mean AOFAS score was 87.43 (95% CI 84.24-90.62) after a mean follow-up of 31.6 months. Univariate and multivariate meta-regression analysis demonstrated that as the percentage of Haraguchi type 1 patients increased, there was a statistically significant improvement in outcome scores. A similar trend was noted for Haraguchi type 3 fractures, and a reverse trend was observed for Haraguchi type 2 injuries, although neither were statistically significant. CONCLUSION Our review suggests that the outcomes of trimalleolar fractures after surgical fixation may depend on the morphology of the PMF, with Haraguchi type 1 fractures having overall superior functional outcomes than Haraguchi type 2 and 3 injuries. Future studies need to done to conclusively prove or refute these findings.

Abstract
Purpose: The aim of this study was to evaluate the post-operative clinical and radiological results of ankle fractures, using three different patient-reported outcome measurements (PROM) and to analyze the results and compatibility of the PROMs.
Materials and Methods: A total of 77 patients were followed up prospectively. Demographic data, fracture side, trauma mechanisms, fracture types, post-operative splint times, initiation of full weight bearing time, and complications were recorded. All patients were evaluated according to the AOFAS, Ankle-Hindfoot Rating Scale, Weber Scoring and Freiburg Scale, at the first-year follow-ups.
Results: The results were good in 57 patients (74%) and poor in 20 patients (26%), according to the AOFAS Scale; excellent in 51 patients (66.2%), good in 12 patients (15.6%) and poor in 14 patients (18.2%) according to the Weber Scoring, and excellent in 50 patients (64.9%), good in 12 patients (15.6%) and poor in 15 patients (19.5%) according to the Freiburg Scale. The results of the PROMs were found to be compatible with each other. Significant relationship was found between the development of complications and the AOFAS Scale and Weber Scoring, and between older age and Weber Scoring.
Conclusion: The results of the AOFAS Scale, Weber Score and Freiburg Scales are compatible with each other and can be safely used in the evaluation of ankle fractures. Development of complications and older age are associated with poor clinical outcomes.

Abstract
OBJECTIVE With or without screw stabilization for diastatic syndesmosis in advanced pronation-external rotation (PE) ankle injuries has not yet been well-determined. Both techniques were retrospectively compared to investigate the superiority of either of the two. METHODS A retrospective cohort study was carried out. From January 1, 2008, to December 31, 2017, 81 consecutive adult patients (average, 42 years; range, 18-78 years; 44 men and 37 women) with advanced PE ankle injuries (stage 3 or 4 PE type) were treated. After malleolar fractures were internally stabilized with screws and plates, the syndesmotic stability was rechecked by external rotation and hook tests. The necessity of cortical screw insertion to stabilize diastatic syndesmosis was decided by the individual orthopaedic surgeon. Postoperatively, a short leg splint was used for 6 weeks. The syndesmotic screw was removed based on the surgeon's policy. The removal of internal fixation for malleolar fractures was required after 1 year. The outcomes of both approaches were compared clinically, and ankle function was compared using the American Orthopaedic Foot and Ankle Society (AOFAS) score. For statistical comparison, the chi-square test was used for categorical data and the Mann-Whitney U test was used for numerical data. RESULTS Seventy-one patients (average, 40 years; range, 18-78 years; 40 men and 31 women) were followed for at least 1 year (87.7%; average, 2 years; range, 1-11 years). Group 1 (with syndesmotic stabilization) had 22 patients and Group 2 (without syndesmotic stabilization), 49 patients. The union rate in Group 1 patients was 100% (22/22), and in Group 2 patients, 91.8% (45/49; p = 0.17). One deep wound infection occurred in Group 1 patients and two in Group 2 patients. Syndesmosis re-diastasis occurred in 13.6% (3/22) of Group 1 patients and 30.6% (15/49) of Group 2 patients (p = 0.13). One syndesmotic screw broke at 6 months. Satisfactory ankle function according to the AOFAS score was noted in 86.4% (19/22) of Group 1 patients and 65.3% (32/49) of Group 2 patients (p = 0.07). CONCLUSION Insertion of syndesmotic screws to promote ligament healing after internal fixation of malleolar fractures in advanced PE ankle injuries may be reasonable.

Abstract
BACKGROUND The incidence of ankle fractures is increasing and the clinical outcome is highly variable. QUESTION What person and fracture characteristics are associated with patient reported outcomes after surgically or conservatively managed ankle fractures in adults? DATA SOURCES Medline, EMBASE, and Allied and Complimentary Health Medical Database (AMED) databases were searched from the earliest available date until 16th July 2020. STUDY SELECTION Prognostic factors studies recruiting adults of age 18 years or older with a radiologically confirmed ankle fracture, and evaluating function, symptoms and quality of life by patient reported outcome measures, were included. STUDY APPRAISAL/SYNTHESIS METHODS Risk of bias of individual studies was assessed by the Quality in Prognostic Factors Studies tool. Correlation coefficients were calculated and data were analysed using narrative synthesis. RESULTS Fifty-one phase 1 explanatory studies with 6177 participants met the inclusion criteria. Thirty-one studies were rated as high risk of bias using the Quality in Prognostic Factors Studies tool. There was low quality evidence that age, body mass index, American Society of Anesthesiologists classification and pre-injury mobility were associated with function, and low to moderate quality evidence that age, smoking and American Society of Anesthesiologists classification were associated with quality of life. No person characteristics were associated with symptoms and no fracture characteristics were associated with any outcomes. CONCLUSION There was low to moderate quality evidence that person characteristics may be associated with patient reported function and quality of life following ankle fracture.

Abstract
INTRODUCTION Recent studies on posterior malleolar fractures mainly focus on the reduction quality and fixation of the posterior fragment since it contributes to ankle stability and articular congruency. However, the association of pre-and postoperative factors considering the whole ankle joint in postoperative functional outcomes remains unclear. Therefore, this study aimed to examine the association between pre-and postoperative variables for postoperative functional outcomes in patients with posterior malleolar fragments (classified as Haraguchi type I or II) and considered the association between reduction and fixation for small posterior malleolar fragments of less than 25% of the intra-articular surface. METHODS This multicenter retrospective cohort study included 110 adult patients who underwent internal fixation for ankle fractures with posterior malleolar fragments. The primary outcome was the American Orthopaedic Foot and Ankle Society (AOFAS) score 12-months postoperatively. As pre-and postoperative variables, the preoperative demographic data, radiographic findings, operative method, postoperative radiographic findings, and complications were evaluated. In addition, univariable and multivariable logistic regression analyses were conducted to examine the association between pre-and postoperative variables and AOFAS scores. RESULTS Twenty-four (21.8%) cases had postoperative complications. Univariate analysis showed that age was significantly according to AOFAS score-stratified groups in patients with Haraguchi type II fractures. Multivariable logistic regression analysis using bootstrapping in the Haraguchi type II group showed that postoperative complications were significantly associated with low AOFAS scores, indicating poor functionality. In both fracture types, postoperative complications had the highest odds ratio among the explanatory variables. In patients with small posterior malleolar fragments, fragment reduction, fixation, and ankle stability were not associated with AOFAS scores. CONCLUSIONS Our results suggest that postoperative complications were associated with AOFAS scores at postoperative 12 months in patients with ankle fractures with posterior malleolar fragments. In patients with small posterior malleolar fragments, reduction and fixation were not associated with AOFAS scores. Therefore, clinical decisions for posterior fragment fixation should be made based on the possible risk of complications related to the surgical procedures in addition to the posterior malleolar fragment size.

Abstract
BACKGROUND Posterior malleolar fractures are found in almost 50% of all ankle fractures. The high clinical relevance of these joint fractures is explained by the significantly worse clinical and functional outcome. There is still a lack of unified opinion regarding the classification and treatment of these fractures. OBJECTIVE The aim of this article is to provide a systematic literature review of clinical studies that investigated posterior malleolar fractures and classified them using one of the three established classifications according to Haraguchi, Bartonicek/Rammelt, or Mason. MATERIAL AND METHODS PubMed was searched without time limits. The systematic literature search was performed according to the current criteria of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The methodological quality of the included studies was quantified using the modified Coleman score. RESULTS A total of 27 studies with a total of 2220 patients were included in this systematic literature review. Trimalleolar fractures showed a significantly less favorable prognosis than other ankle fractures. The quality of reduction was the most important prognostic factor for the clinical outcome. CONCLUSION None of the three classifications examined has become established in the literature. Most of the classifications are weak or should not be used with respect to a derivable treatment algorithm or a prognosis with respect to the outcome. Only the classification according to Bartonicek/Rammelt is suitable to become established in the literature and in clinical practice due to its derivable treatment algorithm.

Abstract
AIM This study aimed to introduce the circle drawing method for the evaluation of marginal impaction associated with posterior malleolar fractures (PMFs) on computed tomography (CT) images and evaluate the marginal impaction based on PMF patterns (Bartonícek classification) in rotational ankle fractures. METHODS From January 2014 to December 2019, A total of 299 patients were reviewed retrospectively. The circle drawing method consists of matching the articular surface of the intact tibial plafond with a best-fitted circle on the sagittal CT image. The mismatch gap between the circle and the articular surface indicates the presence of marginal impaction. To validate the circle drawing method, we assessed CT images of 60 ankles without fracture at the medial, central, and lateral parts using the new method. RESULTS Based on the review of the preoperative CT scan, 153 out of 299 patients (51.2%) were identified as having PMFs. Among them, 57 patients (37.3%) had marginal impaction associated with PMFs. For small posterolateral type 2 fractures, 58% of patients (47/81) had marginal impaction, and its incidence was most frequent among all types (P<.01). For posteromedial extended type 3 fractures, 27% of patients (8/30) had marginal impaction. Extraincisural type 1 and large posterolateral triangular type 4 fractures were rarely associated with marginal impaction. Among the 180 zones of 60 ankles without fracture, 171 zones (95%) were perfectly fitted to a best-fitted circle. CONCLUSIONS The marginal impaction associated with PMFs is often observed in rotational ankle fractures, particularly in small posterolateral and posteromedial extended fractures.

Abstract
Background. There are no established guidelines for fixation of posterior malleolus fractures (PMFs). However, fixation of PMFs appears to be increasing with growing evidence demonstrating benefits for stability, alignment, and early functional outcomes. The purpose of this study was to determine the risk to anatomic structures utilizing a percutaneous technique for posterior to anterior (PA) screw fixation of PMFs. Methods. Percutaneous PA screw placement was carried out on 10 fresh frozen cadaveric ankles followed by dissection to identify soft tissue and neurovascular structures at risk. The distance from the guidewire to each anatomic structure of interest was measured. The correlation between the mean distances from the guidewire to each structure was calculated. Results. The sural nerve was directly transected in 1/10 specimens (10%) and in contact with the wire in a second specimen (10%). There was a significant correlation between the proximity of the guidewire to the apex of Volkmann's tubercle and its proximity to the sural nerve. The flexor hallucis longus (FHL) muscle belly was perforated by the guidewire 40% of the time but was not tethered or entrapped by the screw. Conclusions. Percutaneous PA screw placement is a safe technique which can be improved with several modifications. A mini-open technique is recommended to protect the sural nerve. There may be potential for tethering of the FHL with use of a washer or large screw head. Risk to the anterior and posterior neurovascular bundles is minimal.Levels of Evidence: Level V.

Lisitano L, Mayr E, Rau K, Wiedl A, Reuter J, Foerch S. Accompanying injuries in tibial shaft fractures: how often is there an additional violation of the posterior malleolus and which factors are predictive? A retrospective cohort study. Eur J Trauma Emerg Surg 2022; 48:3171-3176. [PMID: 35076729 PMCID: PMC9360070 DOI: 10.1007/s00068-021-01866-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 12/26/2021] [Indexed: 11/29/2022]
Abstract
Introduction An undislocated fracture of the posterior malleolus is a common concomitant injury in tibial shaft spiral fractures. Nevertheless, these accompanying injuries cannot always be reliably assessed using conventional X-rays. Thus, the aim of the study is to evaluate how often a fracture of the posterior malleolus occurs with tibial shaft fractures (AO:42A/B/C and AO:43A) and which factors—identifiable in conventional X-rays—are predictive. Methods Retrospective evaluation of X-ray and CT images revealed a total of 103 patients with low-energy tibial shaft fractures without direct joint involvement. Proximal fractures and fractures involving the knee were excluded. Basic data on injury, the trauma mechanism, the path of the fracture, bony avulsions of the posterior syndesmosis and the procedures performed were evaluated. Results Thirty-nine fractures were located in the middle third of the tibia, 64 in the distal third. In 65 cases, a spiral fracture (simple or wedge fracture) was found. In 31/103 fractures, an additional osseous avulsion of the posterior syndesmosis could be detected, 5 (16.1%) of them were not recognized preoperatively due to an absence of CT imaging. In three of these patients, a fracture of the posterior malleolus was only recognized postoperatively, and an additional surgery was necessary. The spiral fractures were classified in the a.p. X-ray according to their path from lateral proximal to medial distal (Type A) or from medial proximal to lateral distal (Type B). A Pearson chi-square test and Fisher’s exact test showed a highly significant accumulation of accompanying posterior malleolus fractures for type A fractures (p = 0.001), regardless of the location of the fracture. In addition, the fractures with involvement of the posterior malleolus had a significantly higher proportion in the fractures of the distal third (p = 0.003). There was no statistically significant relationship between the height of the fracture and the path of the fracture (type A or B). These two factors seem to be independent factors for participation of the posterior malleolus. Conclusion In 40.6% of the tibial shaft fractures in the distal third, in 56.9% of the type A spiral fractures and in 67.6% of the type A fractures in the distal third, the ankle joint is involved with bony avulsion of the posterior syndesmosis, which is not always recognized in conventional X-rays. To avoid complications such as additional operations, instability and post-traumatic arthrosis, we recommend preoperative imaging of the ankle using CT for these fractures. Level of evidence III, retrospective cohort study. Trail registration number DRKS00024536.

Evidence-Based Surgical Treatment Algorithm for Unstable Syndesmotic Injuries. J Clin Med 2022; 11:jcm11020331. [PMID: 35054025 PMCID: PMC8780481 DOI: 10.3390/jcm11020331] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 12/26/2021] [Accepted: 01/05/2022] [Indexed: 02/01/2023] Open
Abstract
Background: Surgical treatment of unstable syndesmotic injuries is not trivial, and there are no generally accepted treatment guidelines. The most common controversies regarding surgical treatment are related to screw fixation versus dynamic fixation, the use of reduction clamps, open versus closed reduction, and the role of the posterior malleolus and of the anterior inferior tibiofibular ligament (AITFL). Our aim was to draw important conclusions from the pertinent literature concerning surgical treatment of unstable syndesmotic injuries, to transform these conclusions into surgical principles supported by the literature, and finally to fuse these principles into an evidence-based surgical treatment algorithm. Methods: PubMed, Embase, Google Scholar, The Cochrane Database of Systematic Reviews, and the reference lists of systematic reviews of relevant studies dealing with the surgical treatment of unstable syndesmotic injuries were searched independently by two reviewers using specific terms and limits. Surgical principles supported by the literature were fused into an evidence-based surgical treatment algorithm. Results: A total of 171 articles were included for further considerations. Among them, 47 articles concerned syndesmotic screw fixation and 41 flexible dynamic fixations of the syndesmosis. Twenty-five studies compared screw fixation with dynamic fixations, and seven out of these comparisons were randomized controlled trials. Nineteen articles addressed the posterior malleolus, 14 the role of the AITFL, and eight the use of reduction clamps. Anatomic reduction is crucial to prevent posttraumatic osteoarthritis. Therefore, flexible dynamic stabilization techniques should be preferred whenever possible. An unstable AITFL should be repaired and augmented, as it represents an important stabilizer of external rotation of the distal fibula. Conclusions: The current literature provides sufficient arguments for the development of an evidence-based surgical treatment algorithm for unstable syndesmotic injuries.

Short-term results of gait analysis with the Heidelberg foot measurement method and functional outcome after operative treatment of ankle fractures. J Foot Ankle Res 2022; 15:2. [PMID: 34998420 PMCID: PMC8742407 DOI: 10.1186/s13047-021-00505-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 12/12/2021] [Indexed: 02/07/2023] Open
Abstract
Background Ankle fractures are common fractures in trauma surgery. Several studies have compared gait patterns between affected patients and control groups. However, no one used the Heidelberg Foot Measurement Method in combination with statistical parametric mapping of the entire gait cycle in this patient cohort. We sought to identify possible mobility deficits in the tibio-talar joint and medial arch in patients after ankle fractures as a sign of stiffness and pain that could result in a pathological gait pattern. We focused on the tibio-talar flexion as it is the main movement in the tibio-talar joint. Moreover, we examined the healing progress over time. Methods Fourteen patients with isolated ankle fractures were included prospectively. A gait analysis using the Heidelberg Foot Measurement Method was performed 9 and 26 weeks after surgery to analyse the tibio-talar dorsal flexion, the foot tibia dorsal flexion, the subtalar inversion and the medial arch as well as the cadence, the walking speed and the ground reaction force. The American Orthopedic Foot & Ankle Society ankle hindfoot score was used to obtain clinical data. Results were compared to those from 20 healthy participants. Furthermore, correlations between the American Orthopedic Foot & Ankle Society hindfoot score and the results of the gait analysis were evaluated. Results Statistical parametric mapping showed significant differences for the Foot Tibia Dorsal Flexion for patients after 9 weeks (53–75%: p = 0.001) and patients after 26 weeks (58–70%: p = 0.011) compared to healthy participants, respectively. Furthermore, significant differences regarding the tibio-talar dorsal flexion for patients 9 weeks after surgery (15–40%: p < 0.001; 56,5–70%: p = 0.007; 82–88%: p = 0.033; 97–98,5%: p = 0.048) as well as patients after 26 weeks (62,5–65%: p = 0.049) compared to healthy participants, respectively. There were no significant differences looking at the medial arch and the subtalar inversion. Moreover, significant differences regarding the ground reaction force were found for patients after 9 weeks (0–17%: p < 0.001; 21–37%: p < 0.001; 41–54%: p < 0.001; 60–64%: p = 0.013) as well as patients after 26 weeks (0–1,5%: p = 0.046; 5–15%: p < 0.001; 27–33%: p = 0.001; 45–49%: p = 0.005; 57–59%: p = 0.049) compared to healthy participants, respectively. In total, the range of motion in the tibio-talar joint and the medial arch was reduced in affected patients compared to healthy participants. Patients showed significant increase of the range of motion between 9 and 26 weeks. Conclusions This study shows, that patients affected by ankle fractures show limited mobility in the tibio-talar joint and the medial arch when compared to healthy participants. Even though the limitation of motion remains at least over a period of 26 weeks, a significant increase can be recognized over time. Furthermore, if we look at the absolute values, the patients’ values tend to get closer to those of the control group. Trial registration This study is registered at the German Clinical Trials Register (DRKS00023379).

Evaluation of Ankle Fractures in 228 Patients From a Single Center Using Three-Dimensional Computed Tomography Mapping. Front Bioeng Biotechnol 2022; 10:855114. [PMID: 35372321 PMCID: PMC8965371 DOI: 10.3389/fbioe.2022.855114] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 02/25/2022] [Indexed: 02/05/2023] Open
Abstract
Purpose: The ankle joint has a complex anatomy structure with many causative factors and various injury mechanisms, and the clinical presentation of ankle fractures is diverse. This study aimed to analyze the characteristics of ankle fractures by applicating three-dimensional fracture line mapping technique. Methods: A retrospective study was conducted on 228 patients with ankle fractures. Three-dimensional reconstruction was performed by CT images and the fracture reconstruction model was superimposed onto a standard model of the tibiofibula for fracture line drawing. Then the fracture lines were converted into a three-dimensional coordinate point data set. And the fracture line maps as well as the fracture line heat maps were generated in 3-Matic software and Unigraphics NX software, respectively. Results: The dense area of the fibular fracture lines was located above the tibiofibular joint ligament and wrapped obliquely around the distal fibula from the anterior edge of the fibular neck. The fibular fracture line could be divided into three categories according to the degree of denseness. The dense area of the tibial fracture line is located within the anterior tibial fornix, the anterolateral corner, and the fibular notch. The tibial fracture lines can be classified into four categories according to the density of the fracture lines. The combined medial malleolus + posterior malleolar fracture line situation was found to be not encompassed by the existing AO and Lauge-Hansen (LH) classification systems according to this classification. Conclusion: The 3D fracture line mapping technique can better reflect the distribution of ankle fracture lines and could help to establish a new ankle fracture typing system in the future.

Abstract
BACKGROUND The management of an ankle malunion involving the posterior malleolus remains challenging, and only a few published studies described the operative treatment of complex posterior malleolar malunion. A transfibular approach allows for direct visualization of the articular reduction of the posterior malleolus, but the reports of its use for correcting posterior malleolar malunion are rare. This study aims to evaluate the results of the intra-articular osteotomy via a transfibular approach for correcting an ankle malunion involving the posterior malleolus. METHODS We conducted a retrospective review of 26 patients with a symptomatic malunited ankle fracture involving posterior malleolus were treated with the intra-articular osteotomy via a transfibular approach in our department. Radiographic assessments were performed using plain radiographs and computed tomographic (CT) scans. Clinical outcomes were assessed using the AOFAS ankle-hindfoot score, visual analog scale (VAS), active range of motion of ankle, and the 36-Item Short-Form Health Survey score. RESULTS Postoperatively, anatomic correction of articular surface and anatomic reduction of syndesmosis were achieved in all patients as judged by CT scans. No evidence of progression had been found in 18 of 26 patients (69.2%) at final follow-up. The median AOFAS score improved from 42.0 to 81.5 (P < .001). Median pain VAS score decreased from 6.0 to 1.0 (P < .001). A favorable clinical outcome was associated with a short time interval from original injury to correction surgery and a lower grade of preoperative arthritis, but not with the posterior malleolar fragment size. However, time interval, the posterior malleolar fragment size, and the grade of preoperative arthritis showed no correlation with the progression of arthritis grade after surgery. CONCLUSION An intra-articular osteotomy via a transfibular approach demonstrated an improved function and pain after operative treatment of malunited ankle fracture with a displaced posterior malleolar fragment.

Abstract
BACKGROUND We aimed to compare midterm radiological and clinical outcomes between closed reduction and internal fixation (CRIF) using the fibular intramedullary nail (IMN) and open reduction and internal fixation (ORIF) using the locking plate for the treatment of unstable ankle fractures in active young patients. METHODS In this retrospective cohort study, 204 patients treated with CRIF using the fibular IMN (94 patients) or ORIF using the locking plate (110 patients) were included after at least 3 years of follow-up. The mean patient age was 41.4 years. Radiographic evaluation included the quality of reduction assessed by plain radiography and 3-dimensional (3D)-reconstructed computed tomography as well as the development of posttraumatic osteoarthritis (PTOA) of the ankle assessed by weightbearing plain radiography. Clinical evaluation included the American Orthopaedic Foot & Ankle Society hindfoot score, Olerud and Molander Score, the Foot and Ankle Outcome Score, and visual analog scale pain score as well as complications. RESULTS At median follow-up greater than 4 years, we found no significant differences in measured clinical outcomes between the 2 groups. There were significantly fewer postoperative complications in the IMN group than in the ORIF group (9.5% vs 39%, P < .001). However, we did find a greater proportion of radiographically fair or poor reductions in the IMN group than in the ORIF group (P < .001). The poor reductions in the IMN group were primarily related to Weber type C, pronation-type injury, and comminuted fibular and trimalleolar fractures (P < .001). PTOA was also more frequently observed in the IMN group than in the ORIF group (21.3% vs 9.1%, P = .024). CONCLUSION Given the current prevailing technologies for fracture fixation, this study suggests that surgeons should consider ORIF for unstable ankle fractures in active young patients with Weber type C, pronation-type injury, and comminuted fibular and trimalleolar fractures. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Objectives: To study the value of X-ray analysis method of ankle fracture based on injury mechanism to improve the imaging diagnosis level of ankle fracture. Methods: This study was conducted from January 2016 to December 2019. It included 105 cases of fractures caused by sprained ankle joints. Their age was between 21-81 years with an average of 49.5 years, The traditional X-ray analysis method (Group-A) and the injury mechanism-based ankle fracture X-ray analysis method (Group-B) were used to analyze X-ray image data. Group-B also performed Weber classification and Lauge-Hansen classification on cases. Installment. Results: Of the 105 patients with ankle fractures, 97 patients in Group-B were able to make Lauge-Hansen classification. Of these 97 ankle fractures, 137 were found in Group-A, and 158 were found in Group-B. The wrong diagnosis of fracture in Group-A was 18%, and the wrong diagnosis of fracture in Group-B was 0.5%. There was a statistically significant difference between the two groups (P <0.05). Conclusion: The X-ray analysis method of ankle fractures based on injury mechanism can effectively improve the detection rate of hidden ankle fractures and high fibular fractures, and reduce the missed diagnosis, which is superior to the traditional X-ray analysis methods. At the same time, Weber classification, Lauge-Hansen classification and staging can be made for most cases, which is conducive to guiding clinical treatment.

Abstract
BACKGROUND AND PURPOSE Incidence of posterior malleolar fractures (PMFs) associated with ankle fractures is historically based on plain radiographs. Several classification systems for PMF are currently in use, but the reliability of the Haraguchi classification is not reported. The aim of this diagnostic cohort study was to assess incidence of PMF in patients with AO 44-C fractures, and test the reliability of the Haraguchi fracture classification based on CT. In addition, to evaluate the clinical outcome in patients with PMF. METHODS 210 patients with an AO 44-C type fracture treated with syndesmotic fixation between 2011 and 2017 were included. Presence of PMF was registered, morphology was assessed and classified according to the Haraguchi classification. Interobserver agreement for the Haraguchi classification was evaluated. Patient assessment was conducted at 6 weeks, 6 months, 1 and 2 years. The American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score (AOFAS) was the primary outcome measure. Secondary outcome measures included presence of osteoarthritis. RESULTS 125 of 210 patients (60%) had a PMF. 34% of the PMFs were missed on plain radiographs compared to CT. The interobserver agreement was 0.797, (95% CI: 0.705 to 0.889, p < 0.001), for the Haraguchi classification. The 2-year follow-up rate was 86%. Haraguchi type II fractures had a lower AOFAS compared with the no-fracture group at 6 weeks (mean difference -7.5 (95% CI; -15.0 to -0.2), p = 0.04) and 6 months (mean difference -8.4 (95% CI; -15.3 to -1.5), p = 0.01). Presence of osteoarthritis was higher in patients with Haraguchi type II PMF compared to the no PMF group, this finding was not significant (relative risk (RR) 1.6(95% CI 1.1 to 2.4, p = 0.059)). CONCLUSIONS Plain radiographs underestimated PMF. Patients with a Haraguchi type II fracture had a poorer outcome measured by the AOFAS score compared to no PMF up until 6 months. Classification of PMF according to the Haraguchi classification was reliable.

Abstract
In patients with ankle fractures, the presence of a posterior malleolar fracture has a negative impact on the prognosis. Computed tomography (CT) scanning is essential for fracture classification and treatment planning, as the indication for surgery depends on the 3-dimensional fragment outline and displacement, incisura involvement, and the presence of joint impaction. Anatomic reduction of a posterior malleolar fragment restores the incisura, facilitating reduction of the distal part of the fibula, and it also restores the integrity of the posterior portion of the syndesmosis, reducing the need for additional syndesmotic stabilization. Direct open reduction and fixation of posterior malleolar fragments from a posterior orientation is biomechanically more stable and provides a more accurate reduction than does indirect reduction and anterior-to-posterior screw fixation. Intra-articular step-off of >=2 mm is an independent risk factor for an inferior outcome and the development of posttraumatic arthritis, irrespective of the fragment size.

Abstract
This study reviews the current evidence on the indications and outcomes of the posterolateral approach in the treatment of posterior malleolar fractures. PubMed and Google Scholar search engines were used to construct a review of the literature for all studies detailing the posterolateral approach for posterior malleolar fracture fixation. A total of 11 studies met our inclusion criteria. In total, 332 fractures were identified. Overall superficial infection occurred in 4.5%, skin necrosis in 4.5%, and nerve injury in 4.5%. Hardware irritation that required removal occurred in 13.6%. None of the hardware removals involved posterior malleolus fixation. A total of 51 (15.4%) cases of arthritis were reported, follow-up ranged from a mean of 5.3 months to a mean 7.9 years. Regardless the majority of patient reported outcomes were excellent/good at final follow-up. Thresholds for joint reduction were not uniformly described or even quantified at all in some of the included studies. Variable indications for fixation were reported without reference to posterior malleolus fracture morphology. The posterolateral approach provides a satisfactory approach for fracture reduction with similar complication rates to that reported for other ankle fracture approaches. Further research is required on posterior malleolus fracture morphology, optimal fracture fixation and longer term functional and radiological outcomes.Levels of Evidence: Level III: Systematic review of retrospective cohort studies.

Abstract
BACKGROUND There is a need to assess clinical practice in light of increasing literature recommending fixation of posterior malleolus (PM) fractures. This multicentre study examines treatment approaches, within both Major Trauma Centres and District General Hospitals and role of radiographs and CT scanning. METHODS Trauma lists and databases were used to identify patients and data collected from electronic and paper medical records and imaging systems between August 2017-18. Analysis of treatment and outcomes was then conducted. RESULTS One-hundred-and-sixty ankle fractures were included in the study, only 68 ankle fractures underwent CT scanning following initial radiographs and of these, 65 were managed operatively, with 32 undergoing PM fixation. Syndesmotic stabilisation was performed in 9.6% where the PM was fixed. CONCLUSION CT is still under-utilised, PM fractures that appear to be anything other than small avulsion-type injuries should undergo CT scanning. Syndesmotic stabilisation is statistically less likely to be performed with fixation of the PM.

Abstract
Objective To investigate the effectiveness of fixation the posterior malleolus or not to treat different Haraguchi's classification of posterior malleolus fractures. Methods The clinical data of 86 trimalleolar fracture patients who were admitted between January 2015 and September 2019 and met the selection criteria were retrospectively reviewed. There were 29 males and 57 females; the age ranged from 26 to 82 years with a mean age of 55.2 years. According to Haraguchi's classification, 38 patients were in type Ⅰ group, 30 patients in type Ⅱ group, and 18 patients in type Ⅲ group. There was no significant difference in the general data such as gender, age, and fracture location among the 3 groups ( P>0.05). The fixation of the posterior malleolus was performed in 23, 21, and 5 patients in type Ⅰ, Ⅱ, and Ⅲ groups, respectively. The operation time, fracture healing time, full weight-bearing time, postoperative joint flatness, and joint degeneration degree of the patients in each group were recorded and compared. The American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score was used to evaluate ankle function, including pain, quality of daily life, joint range of motion, and joint stability. The AOFAS scores were compared between fixation and non-fixation groups in each group. Results The procedure was successfully completed by all patients in each group, and there was no significant difference in operation time ( F=3.677, P=0.159). All patients were followed up 12-36 months with a mean time of 16.8 months. At last follow-up, 6 patients were found to have suboptimal ankle planarity, including 2 patients (5.3%) in the type Ⅰ group and 4 patients (13.3%) in the type Ⅱ group, with no significant difference between groups ( χ 2=6.566, P=0.161). The ankle joints of all the patients in each group showed mild degeneration; the fractures all healed well and no delayed union or nonunion occurred. There was no significant difference in the fracture healing time and full weight-bearing time between groups ( P>0.05). No complications such as incision infection, fracture displacement, or plate screw loosening and fracture occurred during follow-up. At last follow-up, the total scores and pain scores of the AOFAS scores in the type Ⅱ group were significantly lower than those in the type Ⅰand Ⅲ groups ( P<0.05), there was no significant difference between groups in the scores for the quality of daily life, joint range of motion, and joint stability between groups ( P>0.05). There was no significant difference in any of the scores between the unfixed and fixed groups, except for the pain and quality of daily life scores, which were significantly lower ( P<0.05) in the unfixed group of type Ⅱ group than the fixed group. Conclusion Haraguchi type Ⅱ posterior malleolus fractures have a worse prognosis than types Ⅰ and Ⅲ fractures, especially in terms of postoperative pain, which can be significantly improved by fixing the posterior malleolus; the presence or absence of posterior malleolus fixation in types Ⅰ and Ⅲ has less influence on prognosis.

Abstract
Ankle fractures with involvement of the posterior malleolus have a poor prognosis. The traditional concept of addressing the posterior fragment as the final step in the surgical reconstruction depending on the fragment size manifest in the lateral X‑ray, does not do justice to the anatomic and biomechanical relevance of the posterior malleolus. Intra-articular step-offs and fragment displacement ≥ 2 mm, impacted intercalary fragments, involvement of the fibular notch and instability of the syndesmosis, represent parameters relevant for the surgical reconstruction and the functional and radiomorphological outcome independent of fragment size. A valid assessment of these parameters can only be achieved via computed tomography (CT) including multiplanar 2D and 3D reconstruction. This is the foundation for the classification of posterior malleolar fractures according to Bartoníček et al., it forms the basis of the preoperative analysis of the fracture components and represents a decision-making tool for the indications for surgery. The individual fracture pattern guides the selection of the suitable approach or a combination of approaches and the surgical strategy. Making use of the posterior approaches enables the surgeon to have a direct view of the fracture components of the posterior malleolus as a precondition for an anatomic reduction. This central surgical step is frequently done as the first measure of the surgical reconstruction of the ankle joint. Furthermore, direct reduction and posterior stabilization is more accurate and stable than indirect reduction from an anterior approach with indirect fixation using lag screws. An additional temporary transfixation of the tibiofibular syndesmosis is often dispensable.

Abstract
AIMS The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size. METHODS This observational prospective cohort study included 70 patients with operatively treated rotational type PMAFs, respectively: 23 Haraguchi Type I (large posterolateral-oblique), 22 Type II (two-part posterolateral and posteromedial), and 25 (avulsion-) Type III. There was no standardized protocol on how to address the PMAFs and CT-imaging was used to classify fracture morphology and quality of postoperative syndesmotic reduction. Quantitative 3D-CT (Q3DCT) was used to assess the quality of fracture reduction, respectively: the proportion of articular involvement; residual intra-articular: gap, step-off, and 3D-displacement; and residual gap and step-off at the fibular notch. These predictors were correlated with the Foot and Ankle Outcome Score (FAOS) at two-years follow-up. RESULTS Bivariate analyses revealed that fracture morphology (p = 0.039) as well as fragment size (p = 0.007) were significantly associated with the FAOS. However, in multivariate analyses, fracture morphology (p = 0.001) (but not fragment size (p = 0.432)) and the residual intra-articular gap(s) (p = 0.009) were significantly associated. Haraguchi Type-II PMAFs had poorer FAOS scores compared with Types I and III. Multivariate analyses identified the following independent predictors: step-off in Type I; none of the Q3DCT-measurements in Type II, and quality of syndesmotic reduction in small-avulsion Type III PMAFs. CONCLUSION PMAFs are three separate entities based on fracture morphology, with different predictors of outcome for each PMAF type. The current debate on whether or not to fix PMAFs needs to be refined to determine which morphological subtype benefits from fixation. In PMAFs, fracture morphology should guide treatment instead of fragment size. Cite this article: Bone Joint J 2020;102-B(9):1229-1241.

[PMID: 32360088 DOI: 10.1016/j.injury.2020.03.064] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 03/17/2020] [Accepted: 03/30/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUNDS Although ankle posterior subluxation is one of the major mechanisms by which posterior malleolar fractures (PMF) contribute to a worse prognosis, there is no parameter to address it quantitatively. So, we suggest a method that can evaluate posterior talar subluxation quantitatively in PMF. METHODS We retrospectively analyzed 37 patients with posterior malleolar fractures. The patients were divided into two groups: PMF without posterior talar subluxation (n = 18) and with posterior talar subluxation (n = 19). We measured the distance between the arc center of the talus and the anterior tibia (TAD), the percentage of articular involvement of the fracture fragment, the inter-fragment distance (IFD) and articular step-off. We analyzed significant differences and the correlations between the two groups for each index. The estimated area of the receiver operating characteristic (ROC) curve was calculated, and cutoff values were suggested to discriminate posterior talar subluxation. RESULTS TAD, IFD, and articular step-off were significantly greater in patients with posterior talar subluxation. (TAD: 14.3 vs. 2.8 mm, p < 0.001, IFD: 7.8 vs. 4.0 mm, p < 0.001, articular step-off: 3.6 vs. 2.0 mm, p = 0.004). The ROC curve showed that TAD was most useful to determine cutoff values for posterior talar subluxation. The area under the curve for TAD was 1.000, and the appropriate cutoff value was 5 mm. When a TAD of > 5 mm was used as a threshold, a sensitivity of 100% and a specificity of 100% were achieved in determining the presence of posterior talar subluxation. Also, higher TAD was correlated with IFD and articular step-off. CONCLUSIONS TAD can be a useful parameter for evaluating the posterior talar subluxation in PMF. It can reflect not only the degree of fracture displacement but also posterior talar subluxation quantitatively.

Mechanism of posterior malleolar fracture of the ankle: A cadaveric study. OTA Int 2020; 3:e060.

Abstract
Objectives: Ankle fracture treatment involves reduction of the bone fragments and stabilization of the joint by reversing the mechanics of injury. For posterior malleolar fracture however, the true mechanism is not understood, leading to a lack of consistent guidance on how to best treat this injury. Methods: Fifteen cadaver ankles were subjected to fracture loading that replicated the Lauge-Hansen pronation-external rotation mechanism. An axial load was applied to each specimen, which was mounted on a materials testing machine, and the foot was rotated externally to failure. Digital video cameras recorded the failure sequence of specific anatomic structures. Results: Posterior malleolar fracture occurred in 7 specimens. Of these, 1 was an intra-articular fracture, another was a fracture involving the entire posterior tibial margin consisting of 2 fragments: that of the posterior tubercle and that of the posteromedial margin of the tibial plafond, with the former judged to be a consequence of avulsion by the posterior inferior tibiofibular ligament and the latter a consequence of axial loading from the talus. In the remaining 5 specimens, the posterior malleolar fracture was a small extra-articular avulsion fracture. Conclusions: Fractures at the posterolateral corner of the distal tibia were shown to be avulsion fractures attributed to the posterior inferior tibiofibular ligament and produced by external rotation of the talus. A fracture involving the entire posterior tibial margin consisting of 2 fragments can be produced by a combination of avulsion by the posterior inferior tibiofibular ligament and axial loading from the talus.
