RESUMO
PURPOSE: Ankle sprains remain the most common soft tissue injury presenting to Emergency Departments. Recently, there has been increased awareness and reporting of deltoid ligament injuries in association with injuries to the lateral ligament complex as well as with fibula fractures. This article reviews the currently available literature on the anatomy of the deltoid ligament, clinical and radiological diagnosis of injuries to the deltoid ligament and treatment recommendations. METHODS: A literature review was conducted for keywords associated with deltoid ligament injuries. MEDLINE, PubMed and Embase databases were utilised for this search. Articles were included if involving an adult population, were English-language, were related to deltoid ligament injuries (with or without associated injuries) and reported on patho-anatomy, clinical or radiological diagnosis or treatment methods. RESULTS: A total of 93 articles were assessed for relevance from the database search, and 47 were included after the removal of irrelevant articles and duplicates. Several studies reported on the clinical findings of deltoid ligament injury, as well as the radiographic analysis. Arthroscopy was considered the gold standard of diagnosis, with authors reporting on the potential benefit of performing arthroscopic repair or reconstruction at the same time. There were no studies that provided a system for the classification of deltoid ligament injury or larger studies of treatment pathways. Long-term studies of the incidence of instability in deltoid ligament injuries were not available. CONCLUSION: There is limited evidence available regarding deltoid ligament injuries, particularly in terms of treatment options, either in isolation or with concomitant injuries. Long-term follow-up studies are needed to obtain more accurate data on the number of complications. LEVEL OF EVIDENCE: Level IV.
RESUMO
Lateral ankle sprain (LAS) is a common injury in sports and daily activities. The present study aimed to determine the prognostic value of clinical and anthropometric parameters in predicting LAS recovery after physiotherapy. Twenty-seven patients with acute LAS were included in this cohort study. First, prognostic factors and anthropometric variables were assessed, along with the time elapsed since the injury, pain score on a visual analogue scale (VAS), navicular drop, ankle range of motion (ROM), and ambulation status. Second, patients received physiotherapy, and their recovery status was assessed using the foot and ankle outcome score (FAOS) questionnaire immediately (first evaluation) and one month after physiotherapy (second evaluation). Univariate regression analysis and stepwise regression were used to evaluate the association between prognostic factors and outcome predictability. The results of this paper have shown that ambulation status was significantly correlated with all FAOS subscales in both the first and second evaluations, except for the FAOS-symptoms (FAOS-Sx) and FAOS-quality of life (FAOS-QOL) subscales in the first evaluation. The eversion ROM was significantly correlated with the FAOS-Sx and FAOS-Sports and Recreational activities (FAOS-Sport/Rec) subscales in the first evaluation. Additionally, age, height, and VAS were significantly correlated with FAOS-activity of daily living (FAOS-ADL) in the first evaluation, so this means that ambulation status is a valuable predictor of treatment success immediately and one month after physiotherapy intervention and compared to other FAOS subscales, the FAOS-QOL subscale is a more reliable predictor of the effectiveness of physiotherapy.

The purpose of this study was to assess whether the type and duration of screw fixation affects ankle joint functional scores and patient activity levels. We evaluated 55 patients who had undergone surgical treatment for ankle fracture with concomitant distal tibiofibular syndesmosis injury. The follow-up period ranged from 2 years to 4 years and 2 months (mean 36 months). Depending on the time of screw removal, patients were divided into 2 groups (the 8-15-week group-19 patients, and the 16-22-week group-36 patients). There were 17 patients with tricortical and 38 patients with quadricortical syndesmosis fixation. The following parameters were assessed: range of motion, rates of complications, level of pain in visual analogue scale (VAS), and function. In the quadricortical fixation group the range of plantar flexion p = .04 and adduction p = .043 were significantly lower in the operated than in the nonoperated limb. In the patients who had their syndesmotic screws removed after 16-22 weeks, the range of plantar flexion in the operated limb was significantly lower than that in the nonoperated limb. We observed no differences between the evaluated groups in terms of ankle joint mobility, VAS pain levels, functional outcomes, or complication rates. All the analyzed subgroups showed poorer ranges of some types of motion in the ankle and worse functional scale and VAS pain scores after treatment in comparison with those before the injury. We suggest removing the syndesmotic screws after 8-15 weeks, due to the possibility of earlier rehabilitation, faster return to work and physical activity and less burden on the health care system. Tricortical or quadricortical syndesmosis fixation is at the surgeon's discretion.
RESUMO
BACKGROUND: Ankle muscle strength should be assessed after a lateral ankle sprain (LAS) because a strength deficit can lead to chronic ankle instability (CAI). No field method is available to obtain quantitative ankle dynamic strength values. This study aimed to assess the reliability of the one-repetition maximal (1-RM) method and to compare ankle muscle strength between healthy volunteers and those with CAI using 1-RM strength assessment approach. METHODS: We recruited 31 healthy volunteers and 32 with CAI. Dorsiflexor, evertor, and invertor 1-RM were performed twice at a one-week interval. The intraclass correlation coefficient (ICC) and minimal detectable change (MDC) were calculated. Strength values were compared between healthy volunteers and CAI. RESULTS: The 1-RM method is reliable for assessing ankle dorsiflexor, evertor, and invertor strength, with an ICC ranging from 0.76 to 0.88, and MDC ranging from 19 to 31%. Volunteers with CAI obtained evertor (3.0 vs. 3.5 N/kg), invertor (2.9 vs. 3.7 N/kg), and dorsiflexor (5.9 vs. 6.5 N/kg) strength values that were lower than healthy volunteers (p < 0.05). CONCLUSION: The 1-RM test can be used in practice to assess evertor, invertor, and dorsiflexor strength during the rehabilitation of LAS. This field method could help practitioners to detect a strength deficit and individualize a strengthening programme if necessary.

BACKGROUND: In suspected Ankle Instability, the parameters that can be defined in the X-ray have their limitation owing to their variability in positioning and rotation of the tibiofibular joint. This inaccuracy further increases due to variability in morphometric parameters of distal tibiofibular syndesmosis among different populations based on race and sex. This research aims to study morphometry of normal distal tibiofibular syndesmosis based on computed tomography imaging in the Indian population. METHODS: An Prospective observational study was performed from December 2020 to October 2022 on normal ankle CT scans of 100 Indian population using axial, sagittal, and coronal CT images. Anterior and posterior tibiofibular distance, Morphology of the incisura fibularis based on depth, Tibiofibular clear space (TFCS) and tibiofibular overlap (TFO), Transverse and longitudinal length of the fibula, and Relationship between the center of the talus and the center of a line joining the outer aspect of malleoli in the coronal plane were measured and analyzed by two different observers. RESULTS: Out of the 100 participants, 77 (77 %) were male, and 23 (23 %) were female. The overall mean age of participants was 34.69 ± 9.7 years. The incisura fibularis was concave in 54 %, and shallow in 46 %. Anterior tibiofibular distance, Posterior tibiofibular distance, and Tibiofibular overlap were significantly different in comparison to the male with female populations (p-value < 0.05). CONCLUSION: This study gives the indices that describe normal variations in the anatomical relationship between the fibula and fibular incisure in the Indian population, which will be helpful for improving the diagnostic accuracy of distal tibiofibular syndesmoses and providing optimal treatment in order to improve functional outcomes and reduce the risk of complications.

RESUMO
OBJECTIVE: To quantify the incidence rate of anterior cruciate ligament (ACL) injuries and ankle sprains according to player sex, playing level, and exposure setting (training vs. games) in basketball players. METHODS: PubMed, MEDLINE, Google Scholar, and ScienceDirect were searched. Only studies reporting the number of ACL injuries and/or ankle sprains alongside the number of athlete-exposures (training sessions and/or games) in basketball players were included. RESULTS: Thirty studies (17 reporting ACL injuries and 16 reporting ankle sprains) were included in the meta-analysis. Higher (p < 0.05) ACL injury incidence rates per 1000 athlete-exposures were recorded in females (female: 0.20 95% confidence intervals [0.16-0.25]; male: 0.07 [0.05-0.08]; female-to-male ratio: 3.33 [3.10-3.57]), in players competing at higher playing levels (amateur: 0.06 [0.04-0.09]; intermediate: 0.16 [0.13-0.20]; elite: 0.25 [0.14-0.64]), and in games (games: female, 0.27 [0.21-0.32]; male, 0.06 [0.03-0.08]; training: female, 0.03 [0.02-0.05]; male: 0.01 [0.00-0.02]; game-to-training ratio: 7.90 [4.88-12.91]). Higher (p < 0.05) ankle sprain incidence rates per 1000 athlete-exposures were observed in males (female: 0.82 [0.61-1.03]; male: 0.90 [0.61-1.19]; female-to-male ratio: 0.91 [0.83-0.99]), in players competing at higher playing levels (amateur: 0.54 [0.51-0.57]; intermediate: 1.12 [1.00-1.24]; elite: 1.87 [1.29-2.46]), and in games (games: 2.51 [1.85-3.16]; training: 0.80 [0.52-0.80]; game-to-training ratio: 2.77 [2.35-3.26]). CONCLUSION: According to player sex, ACL injury incidence rate is higher in females, while ankle sprain incidence rate is greater in males. ACL injury and ankle sprain incidence rates are greater in players competing at higher playing levels and during games compared to training.

BACKGROUND: Identification of anterior tibiotalar ligament (aTTL) injury is essential because it influences the surgeon's treatment option and patient prognosis. PURPOSE: To assess the diagnostic accuracy of the angle measurement between the talus and posterior tibiotalar ligament (talus-pTTL) on magnetic resonance imaging (MRI) in patients with arthroscopically proven aTTL injuries. MATERIAL AND METHODS: Ankle MRI scans of 67 patients who underwent arthroscopic examination were retrospectively reviewed. The talus-pTTL angle on axial T2-weighted MRI and the medial clear space (MCS) on mortise ankle radiograph were measured. Inter-observer agreement of the measurements was calculated. Also, sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC) were the metrics of diagnostic accuracy. RESULTS: AUC was 0.90 for observer 1 with 78.6% sensitivity, 97.4% specificity, 88% accuracy, and 54.7° cutoff value for the talus-pTTL angle. AUC was 0.87 for observer 2 with 85.7% sensitivity, 84.6% specificity, 85.2% accuracy, and 53.7° cutoff value for the talus-pTTL angle. AUC was 0.86 with 82.1% sensitivity, 79.5% specificity, and 80.8% accuracy for observer 1 and 0.79 with 57.1% sensitivity, 92.3% specificity, and 74.7% accuracy for observer 2 for the MCS. Different MCS values and additional capabilities when complemented with the angle measurement showed an increase in diagnostic performances. Intra-observer reliability of MCS and talus-pTTL angle of the two radiologists was excellent. Inter-observer reliability of the two radiologists was excellent for both the talus-pTTL angle (0.95) and the MCS (0.85). CONCLUSION: Measurement of the talus-pTTL angle showed good sensitivity, specificity, and accuracy for the evaluation of aTTL injury with excellent inter-observer reliability.

Understanding the traumatic mechanisms of ankle injuries in soccer is crucial for an accurate and complete MRI diagnosis. Many ankle injuries share universal mechanisms seen in other athletic activities, but certain patterns are found to be more specific and relatively unique to soccer. Ankle impingement syndromes encountered in soccer encompass a spectrum of disorders that include anterior and posterior impingement categories, with anterior impingement representing pathology relatively specific to soccer. Lateral ligamentous sprains are one of the most common injuries; however, there is a higher rate of injuries to the medial structures in soccer as compared to other sports. Ankle fractures are uncommon in soccer while bone contusions and chondral and osteochondral injuries frequently accompany ligamentous sprains. Tendon abnormalities in soccer most commonly result from overuse injuries and typically affect peroneal tendons, posterior and anterior tibialis tendons, and Achilles tendon. Acute Achilles tendon ruptures occur in both recreational players and elite soccer athletes. Tibialis anterior friction syndrome may mimic tibial stress fractures. Long-term sequelae of acute traumatic and chronic overuse ankle injuries in professional soccer players manifest as ankle osteoarthritis that is more prevalent compared to not only the general population, but also to former elite athletes from other sports. This article examines the most common and specific injuries in soccer in order of their frequency.
RESUMO
CONTEXT: Many individuals who sustain a lateral ankle sprain (LAS) fail to return to prior activity due to residual symptoms; and report elevated levels of injury-related fear, decreased function, and decreased health-related quality of life (HRQOL). Additionally, individuals with history of LAS exhibit deficits in neurocognitive functional measures like visuomotor reaction time (VMRT), which contributes to worse patient-reported outcome scores. The aim of this study was to examine the relationship between HRQOL and lower-extremity (LE) VMRT in individuals with LAS history. DESIGN: Cross-sectional. METHODS: Young adult female volunteers with history of LAS (n = 22; age = 24 [3.5] y; height = 163.1 [9.8] cm; mass = 65.1 [11.5] kg; and time since last LAS = 67.8 [50.5] mo) completed HRQOL outcomes including the following: (1) Tampa Scale of Kinesiophobia-11, (2) Fear-Avoidance Beliefs Questionnaire, (3) Penn State Worry Questionnaire, (4) modified Disablement in the Physically Active Scale, and (5) Foot and Ankle Disability Index (FADI). Additionally, participants completed a LE-VMRT task by responding to a visual stimulus using their foot to deactivate light sensors. Participants completed trials bilaterally. Separate Spearman rho correlations were performed to assess the relationship between patient-reported outcomes assessing constructs of HRQOL and LE-VRMT bilaterally. Significance was set at P < .05. RESULTS: There was a strong, significant negative correlation between FADI-Activities of Daily Living (ρ = -.68; P = .002) and FADI-Sport (ρ = -.76; P = .001) scores and injured limb LE-VMRT; moderate, significant negative correlations between the uninjured limb LE-VMRT and FADI-Activities of Daily Living (ρ = -.60; P = .01) and FADI-Sport (ρ = -.60; P = .01) scores; and moderate, significant positive correlations between the injured limb LE-VMRT and modified Disablement in the Physically Active Scale-Physical Summary Component (ρ = .52; P = .01) and modified Disablement in the Physically Active Scale-Total (ρ = .54; P = .02) scores. All other correlations were not statistically significant. CONCLUSIONS: Young adult women with history of LAS demonstrated an association between self-reported constructs of HRQOL and LE-VMRT. As LE-VMRT is a modifiable injury risk factor, future studies should examine the effectiveness of interventions designed to improve LE-VMRT and the impact on self-reported HRQOL.

Introduction Lateral ankle sprain is a common musculoskeletal pathology. Functional exercise progression is vital to restore full function. Aim The aim of this study was to compare the electromyographical response to a standard balance task on one stable and four unstable surfaces. Participants Twenty subjects (5 male, 15 females; age at 23 ± 7.1 years) were recruited to participate in the study. Methods A gym-based single session cross over design was used to compare peak and mean surface EMG (sEMG) activity of the Peroneus Longus, Tibilais Anterior and medial head of the gastrocnemius muscles whilst performing a standardized balance task on one stable surface and four unstable surfaces stable surface. Results A significant main effect for surface was found. Post-hoc testing revealed that the Floor and Trampoline (Trampet) elicited similar mean sEMG response. Discussion The results of the study propose a safe and stepwise progressive rehabilitation regime following ankle injury whilst considering the healing process of the injured structure.

This study aimed to examine differences in the intestinal microbiota diversity in individuals with and without a history of a lateral ankle sprain (LAS). Fifty male college student athletes with (n=32) and without (n=18) a LAS history participated in this study. Faecal samples were collected in the morning after awakening during an off-season, and faecal microbiota were characterized via bacteria 16S rRNA amplicon sequencing. Alpha-diversity metrics and ß-diversity indices were calculated to assess the gut microbiota diversity. The LAS-history group significantly had lower Chao1 (p=0.020) and abundance-based coverage estimators (p=0.035) indices compared to the control group. Gut microbiota composition was not significantly different between athletes with a LAS history and controls (R2 =0.01, p 0.414). Athletes with a history of LASs had significantly higher proportions of Bacteroides Fragilis (p=0.024) and Ruminococcus Gnavus (p=0.021) compared with controls. The gut microbiota of athletes with a LAS history had less richness compared to controls, indicating potential associations between a LAS and the gut microbiota. This study highlights the potential link of a LAS to global health. This study may help raise awareness of strategies to prevent long-term health-related negative consequences in people suffering from LASs.
RESUMO
PURPOSE: This study aimed to validate the angle bisector method on 3D-printed ankle models to reveal whether it aids in placing syndesmotic screws at an accurate trajectory that is patient- and level-specific and also not surgeon-dependent. METHODS: DICOM data of 16 ankles were used to create 3D anatomical models. Then the models were printed in their original size and two trauma surgeons performed the syndesmotic fixations with the angle bisector method at 2 cm and 3.5 cm proximal to joint space. Afterward, the models were sectioned to reveal the trajectory of the screws. The photos of the axial sections were processed in a software to determine the centroidal axis which is defined as true syndesmotic axis and analyze its relationship with the screws inserted. The angle between the centroidal axis and syndesmotic screw was measured by two-blinded observers 2 times with 2 weeks interval. RESULTS: The average angle between the centroidal axis and screw trajectory was 2.4° ± 2° at 2 cm-level and 1.3° ± 1.5° at 3.5 cm-level, indicating a reliable direction with minimal differences at both levels. The average distance between fibular entry points of the centroidal axis and screw trajectory was less than 1 mm at both levels indicating that the angle bisector method can provide an excellent entry point from fibula for syndesmotic fixation. The inter- & intra-observer consistencies were excellent with all ICC values above 0.90. CONCLUSION: The angle bisector method provided an accurate syndesmotic axis for implant placement which is patient- & level-specific and not surgeon-dependent, in 3D-printed anatomical ankle models.

OBJECTIVES: To determine if point-of-care ultrasound (POCUS) of ankle injuries in children, in conjunction with validated ankle injury clinical prediction rules, can accurately diagnose ankle fracture in children. METHODS: A prospective observational study was conducted on patients (birth-21 years) presenting to a pediatric emergency department with an ankle injury requiring ankle radiograph. POCUS of the injured ankle was performed to evaluate for fracture. Clinical prediction rule scores (Ottawa Ankle and Low Risk Ankle) were recorded along with pre- and post-ultrasound clinical suspicion for fracture. Diagnosis of ankle fracture was confirmed via radiology radiograph report. Test characteristics of sensitivity, specificity, positive and negative predictive values were calculated. RESULTS: Forty-eight patients were enrolled, 58% were female, with a mean age of 12.2 years (SD 3.8). Twelve (25%) patients had ankle POCUS positive or indeterminate for fracture. Nine (19%) patients had fracture based on radiograph, and 6 of the 9 (67%) patients with fracture had open growth plates. Ankle POCUS was found to have a sensitivity of 56% (95% confidence interval [CI], 23-85%), specificity of 82% (95% CI, 66-92%), positive predictive value of 42% (95% CI, 17-71%), and negative predictive value of 89% (95% CI, 73-96%). CONCLUSIONS: Our findings suggest that ankle POCUS in children is a difficult application to perform and interpret compared with radiographic diagnosis of fracture. Open growth plates may complicate accurate identification of fracture using POCUS and at this time serves as a poor screening exam to assess for fracture or the need for radiographs.

BACKGROUND: Diclofenac diethylamine (DDEA) gel has demonstrated efficacy for treatment of ankle sprains in both the 1.16% four-times-daily (QID) and 2.32% twice-daily (BID) formulations. The objective of this study was to compare, for the first time, the efficacy of DDEA 2.32% gel BID and DDEA 1.16% gel QID. METHODS: This was a phase 3, randomized, double-blind, multicenter, active-controlled, parallel-group study conducted in China from October 2019 to November 2020, designed to determine the noninferiority of DDEA 2.32% gel BID relative to DDEA 1.16% gel QID for treatment of grade I-II ankle sprain. At study entry, patients must have had pain on movement (POM) ≥50 mm on a 100-mm visual analogue scale (VAS), and not received any pain medication. The primary efficacy endpoint was the noninferiority of DDEA 2.32% gel BID vs DDEA 1.16% gel QID for POM as assessed by the patient using the 100-mm VAS, conducted on day 5. Secondary endpoints included measures of ankle tenderness, joint function, swelling, and patient-reported pain intensity and pain relief. RESULTS: A total of 302 patients were randomized and 95.4% completed the study. The mean (SD) change in POM from baseline to day 5 using the 100-mm VAS was - 42.8 mm (19.7 mm) with DDEA 2.32% gel BID and - 43.1 mm (18.1 mm) with DDEA 1.16% gel QID for the per-protocol population. The least squares mean difference (DDEA gel 2.32% - DDEA gel 1.16%) at this timepoint was 1.11 mm (95% CI - 3.00, 5.22; P = 0.595), and the upper limit (5.22 mm) of the 95% CI was less than the noninferiority margin of 13 mm, demonstrating that DDEA 2.32% gel BID was noninferior to DDEA 1.16% gel QID. Similar trends were seen for the secondary efficacy endpoints. There was no significant difference in the incidence of treatment-emergent adverse events or adverse events adjudicated as being treatment related. All treatment-related adverse events were dermatological; one patient discontinued from the DDEA 2.32% gel BID arm due to application-site inflammation. CONCLUSIONS: DDEA 2.32% gel BID offers a convenient alternative to DDEA 1.16% gel QID, with similar pain reduction and relief, anti-inflammatory effects, and tolerability. TRIAL REGISTRATION: NCT04052620.

PURPOSE: Neuromuscular training (NMT) is effective at reducing football injuries. The purpose of this study was to document the use of NMT to prevent anterior cruciate ligament injuries and lateral ankle sprains in adult amateur football and to identify barriers for using NMT. METHODS: A preseason and in-season online survey was completed by players and coaches of 164 football teams. The survey contained questions concerning injury history, type and frequency of NMT, and barriers when NMT was not used. RESULTS: A total of 2013 players (40% female) and 180 coaches (10% female) completed the preseason survey, whereas 1253 players and 140 coaches completed the in-season survey. Thirty-four percent (preseason) to 21% (in-season) of players used NMT, but only 8% (preseason) to 5% (in-season) performed adequate NMT (i.e. both balance and plyometric exercises, at least twice per week). In the subpopulation of players with an injury history, 12% (preseason) and 7% (in-season) performed adequate NMT. With respect to the coaches, only 5% (preseason) and 2% (in-season) implemented adequate NMT. Most important barriers for using NMT for both players and coaches were a lack of belief in its effectiveness, a lack of knowledge, the belief that stretching is sufficient, and not feeling the need for it. CONCLUSION: Most amateur football teams do not implement essential components of NMT. The results highlight the urgent need for developing strategies to enhance the adequate use of NMT in amateur football. LEVEL OF EVIDENCE: II.

In 2020 a total of 126 patients attended the practice with distortion trauma of the ankle. Based on a thorough clinical and ultrasound examination 25 ligamentous injuries of the anterior talofibular ligament (ATFL, 9.8%), 8 osseous ligament avulsions (6.3%), 7 injuries of the lateral calcaneocuboid ligament (CC ligament, 5.6%), 5 lesions of the calcaneofibular ligament (CFL) each combined with ATFL injuries (3.9%) and 1 syndesmosis injury (0.6%) were recorded. This didactic article presents a comprehensible ultrasound examination course in an instructive manner from the clinical practice. Identification of osseous and ligamentous landmarks is often difficult clinically and even in an anatomical preparation but it can easily be done using ultrasound. Hemarthrosis of the ankle has a high predictive value with respect to an associated ligament tear and is easily detectable by ultrasound. Injuries of the ATFL, the anterior syndesmosis and damage to the lateral malleolar epiphysis can easily be clearly distinguished sonographically. A positive decompression test confirms the distal avulsion of the ATFL. Sonographic stability testing of the AFTL can be carried out immediately after the clinical examination in the same position and visualized on the monitor. The talofibular advance can be measured on the monitor. Instability of the anterior syndesmosis can be visually demonstrated on the monitor using the sonographic Frick test. A final ultrasound control on the monitor confirms the structural healing and the re-establishment of ligamentous stability.

PURPOSE: Stable Weber B ankle fractures are treated by a walking boot for 6 weeks and bearing full weight through the boot as tolerated. The aim of the present study was to assess the outcome parameters of this treatment protocol, evaluate the efficacy of using the walking boot, and investigate any possible predicting factors that could affect the outcomes. METHODS: All the patients with stable Weber B ankle fractures, treated in our hospital between January 2018 and December 2018, were prospectively included to the study. The patients were evaluated clinically, and the patient-reported outcome measures data were collected at the 2 and 6 weeks post-injury. Chi square, Spearman's rho test, independent samples and paired sample t-tests were used for the monovariant analysis. RESULTS: A total of 128 consecutive patients (aged 52.2 ± 19.1 years) with supination external rotation type 2 fracture were finally included to the study. At the 2 weeks follow-up, the reported outcome measures scores were in moderate levels, but improved significantly at the 6 weeks follow-up (p < 0.0001). Multivariant analysis revealed that the ability to bear full weight without the boot at the 2 weeks after diagnosis was the only variable, which made statistically unique contribution to the foot and ankle disability index score at the 6 weeks (p = 0.005). CONCLUSION: Conservative treatment using a walking boot with advice to bear full weight of stable ankle Weber B fractures can bring to good functional outcomes. The ability to bear full weight without the aid of the walking boot at 2 weeks after diagnosis was the only significant predicting factor for better outcomes at 6 weeks after diagnosis.

The Lauge-Hansen ankle fracture classification system is widely accepted and is utilized to describe and predict ankle fracture patterns based on the mechanism of injury. Multiple studies have shown inconsistencies in the Lauge-Hansen's ability to predict fracture patterns based on the mechanism of injury. We set out to determine if the posterior malleolar fracture pattern is associated with the fracture types described by Lauge-Hansen. In this retrospective cohort study, we reviewed 153 patients with trimalleolar ankle fractures as diagnosed using computed tomography scans. Timing of injury was from February 2013 to August 2017. Patient ages ranged between 18 and 89 years old. Each patient had a complete clinical and radiographic workup including a preoperative computed tomographic scan following initial fracture reduction in the emergency room. We classified each ankle fracture based on plain film radiographs using the Lauge-Hansen classification scheme. Each individual posterior malleolar fracture was evaluated on computed tomography imaging and described using both the Haraguchi and Bartonicek-Rammelt classification systems. Of the 153 patients identified with trimalleolar ankle fractures, 70% were female (±20%), the mean age was 51 y (±8 y), and the mean body mass index was 30 kg/m2 (±3 kg/m2). We did not observe a significant association between the Lauge-Hansen injury mechanism and either the Bartonicek-Rammelt or the Haraguchi trimalleolar ankle fracture classification systems (chi-square correlation tests p > .05).
RESUMO
Ankle injuries are highly prevalent in ballet, with strength highlighted as a primary risk factor. To profile ankle strength, fourteen female ballet dancers (age: 19.29 ± 1.59 years) completed an isokinetic testing protocol comprising concentric eversion (CONEV) and inversion (CONINV), and, eccentric inversion (ECCINV) trials at four angular velocities (30° · s-1, 60° · s-1, 90° · s-1, 120° · s-1) for both the dominant and non-dominant limb. In addition to Peak Torque (PT) and the corresponding Dynamic Control Ratios (DCRs), angle-specific derivatives of strength (AST) and Functional Range (FR) were calculated. There was no evidence of any significant bilateral strength asymmetry (p = 0.90) across all metrics, and no significant interactions with limb and contraction mode or velocity. A significant main effect for contraction mode (p = 0.001) highlighted greater ECCINV strength - which was maintained with increasing isokinetic velocity - in contrast to reductions in CONEV and CONINV strength. Specifically, dancers are ECCINV dominant at angular velocities greater than 60° · s-1, which is likely to be characteristic of most functional tasks. The lack of bilateral asymmetry may be attributed to dance training interventions that facilitate bilateral development, but ipsilateral mode and velocity-specific asymmetries have implications for injury risk and the training needs of female ballet dancers.

Osteochondral lesions (OCL) of the talus are defined as chondral damage with subchondral involvement. The traumatic etiology is important; in particular, sprains and fractures can lead to lesions of the articular surface and the subchondral plate. As a result, unstable lesions and subchondral cysts can trigger substantial persistent pain and functional impairments. A primary conservative treatment can be considered and is especially recommended in children and adolescents; however, return to previous sports activity and level is often not achieved. The principles of reconstructive surgical management include internal fixation of osteochondral fragments, bone marrow stimulation, autologous membrane-augmented chondrogenesis⯱ bone grafting, osteochondral transfer, retrograde techniques⯱ bone grafting, (matrix-associated) autologous chondrocyte implantation and autologous osteoperiosteal graft from the iliac crest. Additional surgical procedures for ankle stabilization and deformity correction should be considered if necessary.
