Effect of Postoperative Immobilization Time on PROMIS Scores and Clinical Outcomes in Ankle Fracture Patients

Category:Ankle; TraumaIntroduction/Purpose:Ankle fractures are among the most common injuries that Orthopaedic Surgeons treat; yet, little guidance exists in postoperative protocols for ankle fractures concerning time of immobilization and weightbearing. Results from previous studies have been mixed; demonstrating improved outcomes, no difference in outcome, or poorer outcomes including increased wound complications in patients who are mobilized early. Here, we aim to investigate the association between early immobilization and patient reported outcomes. Our null hypothesis was that no difference in PROMIS scores would be identified in patients when comparing the effect of time of immobilization and time of weightbearing.Methods:A chart review identified ankle fractures that underwent surgical fixation between 2015 and 2020 at a level 1 trauma center and its associated facilities. One-hundred nineteen patients from 8 providers met inclusion criteria for our final analysis. Fifty patients were immobilized for <6 weeks and 69 patients were immobilized for at least 6 weeks. Our primary outcome measures included the PROMIS questionnaire, time of immobilization, and time to full weightbearing. Our secondary outcome measures included time to return to work, wound complications (infection, delayed healing), and complications associated with fracture fixation (loss of reduction, delayed union, reoperation, hardware failure). Repeated-measures ANOVAs were used to predict each of the PROMIS outcomes of anxiety, depression, physical function, and pain interference. Each model included the predictors of age, sex, race, BMI, payor, provider, time to radiographic union, time to return to work, time to full weightbearing, and early vs late immobilized groups.Results:There were no differences in PROMIS scores between mobilization groups and time to full weightbearing (p>0.05). Furthermore, there were no differences in wound complications nor complications associated with fracture fixation (p>0.05). Across our cohort, physical function scores were negatively impacted by higher BMI, increasing age and longer time to return to work/play (p<0.05). Our analysis further showed that depression, anxiety, pain interference and physical function levels improve as a function of time (p<0.05). African Americans showed more pain interference than other groups of patients (p<0.05). No difference in PROMIS scores were identified between treating providers (p>0.05).Conclusion:In this study, the null hypothesis was accepted. Data from our analysis shows no significant differences between the early and late mobilization and weightbearing groups in terms of PROMIS outcomes nor with wound complications and complications associated with fracture fixation. Our study does suggest that early mobilization after operative treatment of ankle fractures is safe and results in similar patient reported outcomes with no increased risk of complication. We did find that African American patients experienced more pain that other groups and we aim to further explore this topic to find potential modalities to address this disparity.

Lateral Patient Positioning for Pilon and Trimalleolar Ankle Fractures

Category:Ankle; TraumaIntroduction/Purpose:Preoperative planning for pilon and trimalleolar ankle fractures can be difficult. Due to fracture complexity, staged open reduction and internal fixation (ORIF) is performed, resulting in two surgeries. For other situations, definitive fixation occurs with one surgery. However, patients require both prone and supine positioning in order to address all fracture components. Repositioning, re-prepping and re-draping adds to operating room (OR) time and time under anesthesia, increasing the risk for anesthesia related complications. Additionally, repositioning the patient can potentially increase fluoroscopy time and radiation exposure to the patient. Lateral patient positioning obviates many of these concerns. Our study goal was to assess the safety and effectiveness of lateral positioning for pilon and trimalleolar ankle fracture ORIF compared with patients placed in standard positioning (i.e supine/prone).Methods:This was a retrospective cohort analysis of 41 patients who underwent operative fixation of a pilon or trimalleolar ankle fracture at a single institution level 1 trauma center. This study compared outcome data for those undergoing the procedure in lateral positioning (n=31) vs. standard (prone/supine) positioning (n=10). Exclusion criteria included pregnant women, prisoners, patients with less than 6 weeks of follow-up, previous or bilateral pilon or ankle fracture surgery or patients treated with limited internal fixation and external fixation. Variables collected included patient demographics, time to union, time to weightbearing, complications and any repeat surgeries. Additionally, chart review was performed analyzing OR time, fluoroscopy time and radiation dose to patient.Results:The patients fixed in the lateral position underwent significantly less time in the OR and subsequent time under anesthesia (p= 0.02). The average OR time in the lateral positioning group was 160 minutes (min) (range: 65-234 min). The average OR time in the standard positioning group was 193 minutes (range: 143- 263 min). Fluoroscopy time was less in the lateral group compared with the standard group (1.47 vs 2.09 min), though this was not statistically significant. Mean patient radiation dose was less in the lateral position group, but without statistical significance (3.22 vs 3.66 mGy). Compared with the standard positioning group, the lateral group demonstrated a significantly shorter time to weightbearing both in (avg 7.8 weeks) and out (avg 11.8 weeks) of the walking boot (p= 0.01). There were no significant differences in complications or time to fracture union.Conclusion:Our results demonstrated that patients treated in the lateral position progressed in their weightbearing faster without increased risk of complications or delayed union, compared with the standard positioning group. Additionally, perhaps the most intriguing conclusion from our study was that OR time, and therefore time under anesthesia was significantly improved with lateral positioning. Fluoroscopic time and radiation dose exposure were also found to be less on average in the lateral positioning group. Our study suggests that lateral positioning for ORIF of pilon or trimalleolar fractures may not only improve patient safety but also reliably lead to acceptable patient outcomes.

Association of Length of Stay and COVID-19 in Rotational Ankle Fracture Surgery in the National COVID Cohort Collaborative (N3C)

Category:Ankle; TraumaIntroduction/Purpose:Coronavirus (COVID-19) is an emerging, rapidly evolving situation. The National COVID Cohort Collaborative (N3C) is an innovative approach to integrate real-world clinical observations into a harmonized database. To investigate the outcomes of adults with ankle fracture surgery during the (COVID-19) pandemic, we had the following research question: What are the outcomes of ankle fracture patients with COVID-19 (invasive ventilation, length of stay, death)? The purpose of this abstract is to introduce the largest cohort of ankle fracture patients to date with a comparison between lab- confirmed COVID-19-positive and COVID-19-negative.Methods:A retrospective cohort of adults with ankle fracture surgery in the N3C Data Enclave. The N3C Data Enclave is an NIH-funded, secure platform through which the harmonized clinical data from electronic health records is stored (https://covid.cd2h.org/). COVID-19 status was determined using a set of 55 SARS-CoV-2 polymerase chain reaction and antigen lab tests. Ankle fracture surgery was defined using SNOMED codes for 'fracture of bone' and one of the following CPT codes '27766, 27769, 27792, 27814, 27822, 27823, 27829' for 'ankle fracture surgery.'Results:A total population of 3.4 million patient records was queried in the National COVID Cohort, identifying 2,032 participants with ankle fracture surgery. The age range of the overall group was 18-98 years. Comparing COVID-19-positive to COVID-19-negative, the age (48.9 years vs 47.7 years) and gender (66.7% female vs 55.1% female) distribution of each group were comparable (both p>0.05). COVID-19-positive comprised 2.4% of the group (n=48). The length of stay was 4.7 days longer in the COVID-19-positive group (8.7 days vs 4.0 days, p<0.001). Higher proportions of COVID-19-positive patients who required invasive ventilation (12.5% vs 3.2%, p<0.002). The number of outcomes for mortality was too few to report.Conclusion:Based on the initial results, rotational ankle fractures requiring surgery necessitated longer hospitalizations in COVID-19-positive patients during the COVID-19 pandemic than in patients without the virus. The average increased length in hospitalization was, on average, about 6 days. When treated in isolation, ankle fractures can often be treated on an outpatient basis, and a multiple-day increase in average hospital stay is substantial. Though the overall complication profiles (with the exception of pulmonary disease) were similar, lengthy hospital stays could lead to delays in the recovery and rehabilitative process, and functional outcomes could not be determined in our study.

COVID-positive ankle fracture patients are at increased odds of perioperative surgical complications following open reduction internal fixation surgery.

IntroductionAnkle fractures have continued to occur through the COVID pandemic and, regardless of patient COVID status, often need operative intervention for optimizing long-term outcomes. For healthcare optimization, patient counseling, and care planning, understanding if COVID-positive patients undergoing ankle fracture surgery are at increased risk for perioperative adverse outcomes is of interest.MethodsThe COVID-19 Research Database contains recent United States aggregated insurance claims. Patients who underwent ankle fracture surgery from April 1st, 2020 to June 15th, 2020 were identified. COVID status was identified by ICD coding. Demographics, comorbidities, and postoperative complications were extracted based on administrative data. COVID-positive versus negative patients were compared with univariate analyses. Propensity-score matching was done on the basis of age, sex, and comorbidities. Multivariate regression was then performed to identify risk factors independently associated with the occurrence of 30-day postoperative adverse events.ResultsIn total, 9,835 patients undergoing ankle fracture surgery were identified, of which 57 (0.58%) were COVID-positive. COVID-positive ankle fracture patients demonstrated a higher prevalence of comorbidities, including: chronic kidney disease, diabetes, hypertension, and obesity (p<0.05 for each). After propensity matching and controlling for all preoperative variables, multivariate analysis found that COVID-positive patients were at increased risk of any adverse event (odds ratio [OR] = 3.89, p = 0.002), a serious adverse event (OR = 5.48, p = 0.002), and a minor adverse event (OR = 3.10, p = 0.021).DiscussionCOVID-positive patients will continue to present with ankle fractures requiring operative intervention. Even after propensity matching and controlling for patient factors, COVID-positive patients were found to be at increased risk of 30-day perioperative adverse events. Not only do treatment teams need to be protected from the transmission of COVID in such situations, but the increased incidence of perioperative adverse events needs to be considered.

Utility of WBCT to Diagnose Syndesmotic Instability in Patients With Weber B Lateral Malleolar Fractures.

Diagnosing syndesmotic instability accompanying Weber B ankle fractures can be challenging. This study aimed to evaluate the ability of weight-bearing computed tomography (WBCT) to diagnose syndesmotic instability using one-dimensional, two-dimensional, and three-dimensional measurements among patients with unilateral Weber B lateral malleolar fractures with symmetric medial clear space (MCS) on initial radiographs and yet demonstrated operatively confirmed syndesmotic instability. The treatment group included 23 patients with unilateral surgically confirmed syndesmotic instability accompanying Weber B ankle fractures who underwent preoperative bilateral foot and ankle WBCT. The control group included 18 unilateral Weber B ankle fracture patients without syndesmotic instability who underwent bilateral WBCT. Measurements on WBCT images included the following: (1) syndesmotic area, (2) anterior, middle, and posterior distal tibiofibular distance, (3) fibular rotation, (4) distance from fibular tip to plafond, (5) fibular fracture displacement, and (6) MCS distance. In addition, the following volumetric measurements were calculated: (1) syndesmotic joint volume from the tibial plafond extending to 3 and 5 cm proximally, (2) MCS volume, and (3) lateral clear space volume. Area under the receiver operating characteristic curve analysis and Delong test were used, and optimal cutoff values to distinguish between stable and unstable syndesmosis were determined using Youden J statistic. Among patients with unilateral syndesmotic instability and Weber B ankle fractures, all WBCT measurements were significantly greater than uninjured side, except MCS distance, syndesmotic area, and anterior and posterior tibiofibular distances (P values <0.001 to 0.004). Moreover, syndesmosis volume spanning from the tibial plafond to 5 cm proximally had the largest area under the curve of 0.96 (sensitivity = 90%; specificity = 95%), followed by syndesmosis volume up to 3 cm proximally (area under the curve = 0.91; sensitivity = 90%; specificity = 90%). Except for MCS volume and distal fibular tip to tibial plafond distance, the control group showed no side-to-side difference in any parameter. Syndesmotic joint volume measurements seem to be best suited to diagnose syndesmotic instability among patients with Weber B ankle fractures, compared with other two-dimensional and three-dimensional WBCT measurements. Level III, comparative diagnostic study.

The influence of size and comminution of the posterior malleolus fragment on gait in trimalleolar ankle fractures

BackgroundAnkle fractures involving the posterior malleolus generally lead to worse outcome. However, no studies on gait in trimalleolar ankle fractures have evaluated the influence of size and comminution of the posterior malleolar fragment. MethodsWe expected patients with more severely comminuted posterior malleolus, more severe fracture type and larger posterior fragment to have reduced gait kinematics and poorer patient-reported outcomes. 26 trimalleolar ankle fracture patients were compared with 14 healthy controls and kinematically analyzed using the Oxford Foot Model. Functional outcome was based on 4 patient reported outcome questionnaires. Effects of posterior fragment size, comminution and Haraguchi fracture classification were determined on conventional and 3D CT-scans. FindingsTrimalleolar patients had lower walking speed and reduced range of motion between the hindfoot and tibia in both loading and push-off phases in the sagittal and transverse planes. The range between the hindfoot and tibia in the sagittal plane in the push-off phase correlated significantly with patient reported outcomes. The absolute and relative surface area of the posterior fragment on conventional CT-scans and 3D CT-scans, correlated significantly with range of motion. Patients with a posterior malleolus size >10% of the posterior malleolus had lower flexion-extension between forefoot and hindfoot during loading phase than patients with a size ≤10%. InterpretationTrimalleolar fractures reduce walking speed and range of motion in the talocrural joint. Reduced range in the talocrural joint is associated with poorer outcomes. Posterior fragment size correlated significantly with range of motion in talocrural and midfoot joints and with patient reported outcomes.Level of evidence: Level 3, retrospective study.

Association Between Opioid Use and Diabetes in Patients With Ankle Fracture Repair.

Ankle fractures in patients with diabetes mellitus have long been recognized as a challenge to practicing clinicians. Ankle fracture patients with diabetes may experience prolonged healing, higher risk of hardware failure, an increased risk of wound dehiscence and infection, and higher pain scores pre- and postoperatively, compared to patients without diabetes. However, the duration of opioid use among this patient cohort has not been previously evaluated. The purpose of this study is to retrospectively compare the time span of opioid utilization between ankle fracture patients with and without diabetes mellitus. We conducted a retrospective cohort study using our institution's TriNetX database. A total of 640 ankle fracture patients were included in the analysis, of whom 73 had diabetes. All dates of opioid use for each patient were extracted from the data set, including the first and last date of opioid prescription. Descriptive analysis and logistic regression models were employed to explore the differences in opioid use between patients with and without diabetes after ankle fracture repair. A 2-tailed P value of .05 was set as the threshold for statistical significance. Logistic regression models revealed that patients with diabetes are less likely to stop using opioids within 90 days, or within 180 days, after repair compared to patients without diabetes. Female sex, neuropathy, and prefracture opioid use are also associated with prolonged opioid use after ankle fracture repair. In our study cohort, ankle fracture patients with diabetes were more likely to require prolonged opioid use after fracture repair. Level III, prognostic.

Investigating the Radiological Outcomes of Syndesmosis Injuries in Ankle Fracture Patients After Suture Button Fixation

Concomitant syndesmotic injury occurs in 10% of ankle fractures. Anatomic reduction and maintenance of this reduction is critical in ensuring ankle stability and preventing long-term complications. This is a retrospective cohort study aimed at evaluating the mid-term radiological outcomes of syndesmotic injuries in ankle fracture patients after surgical fixation with suture button device. The study group included 33 patients. Plain radiographs including anteroposterior, lateral and mortise views of the affected ankle were performed preoperatively, postoperatively and at 3-month follow-up. Anteroposterior views were used to measure the amount of tibiofibular overlap and tibiofibular clear space. Paired Student's t test and linear model regression were performed. Between the immediate postoperative and 3-month follow-up period, there was a mean decrease in tibiofibular overlap of 0.841 (±2.07) mm (p = .0259). There was a mean increase in tibiofibular clear space of 0.621 (±1.46) mm (p = .0201). In addition, we found significant correlation between fracture type and change in tibiofibular clear space (p = .047). Our study showed that there is statistically significant widening of the syndesmosis after suture button fixation at 3-month follow-up as evidenced by reduced tibiofibular overlap and increase in tibiofibular clear space. However, they remain within the maximum threshold for acceptable syndesmotic widening of 1.5 mm. Further correlation between radiological outcomes and patient function is needed to determine clinical significance of these changes.

Can the implementation of the Opioid Start Talking form impact the amount of opioid use in patients after ankle fracture repair?

As part of 2018 legislation aimed at fighting the opioid epidemic, the Michigan Department of Health and Human Services (MDHHS) published the "Opioid Start Talking" (OST) Form on June 1, 2018. We examined if the implementation of the OST form led to an identifiable decrease in patient opioid use. Specifically, we examined the opioid prescription quantities in patients who sustained ankle fractures that required open reduction internal fixation (ORIF). Retrospective. Hospital medical records and Michigan Automated Prescription Database (MAPS) were analyzed for similar ankle fracture patients operated on by two surgeons prior to and after the initiation of the OST form. Records allowed us to track opioid filling through MAPS for 120 days after surgery in two groups: preimplementation (PRE) and post-implementation (POST) OST groups. The gathered data were analyzed by the investigators along with a staff statistician. Single-institution orthopedic practice. Seventy eight patients Main outcome measure: Average morphine milligram equivalent (MME) per patient encounter. Seventy eight patients were included in the final analysis after applying the exclusion criteria. There were 38 patients in the pre-OST form period and 40 in the post-OST form period groups. The pre-OST and post-OST groups were well matched between the two surgeons. There was no evidence of a statistically significant difference found in the median MME between patients from the pre-period group to the post-period group (median 59 vs 50, P = 0.61). In regard to the injury pattern, the bimalleolar MME median was 50 (38 = 25th percentile, 67 = 75th percentile; min-max 0-175) and the trimalleolar median MME was 63 (39 =25% percentile, 81 = 75th percentile; min-max 0-249) with a P value of 0.20. Overall, the administration of the OST form to patients with ankle fractures did not result in a decrease in MMEs prescribed within 120 days of surgery. Although it is a start in the battle against the opioid epidemic, further evaluation of the effectiveness of the OST form is necessary.

The Value of CT 3D Reconstruction in the Classification and Nursing Effect Evaluation of Ankle Fracture.

Aim To study the application value of ankle fracture classification and diagnosis. In this paper, the clinical data of 100 cases of ankle fracture patients admitted from May 2020 to May 2021 were analyzed by CT 3D reconstruction. All patients received surgical treatment and underwent spiral CT 3D reconstruction and X-ray examination before surgery. The results showed that 20 cases (20.00%) of the 100 cases were PER, 24 cases (24%) of the 100 cases were PAB, 31 cases (31%) of the 100 cases were SER, and 25 cases (25%) of the 100 cases were SAB, respectively. Conclusion The diagnostic accuracy of CT 3D reconstruction for different types of ankle fracture is higher than that of X-ray, and the differences are statistically significant (P < 0.05). CT 3D reconstruction is applied in the early diagnosis of ankle fracture, which can accurately detect the classification of patients. It has important clinical application value and can be used as the first choice for the early classification diagnosis of ankle fracture.

BACKGROUND Ankle fractures are among the most common injuries encountered by orthopaedic surgeons. An ankle is considered unstable when the loss of normal constraints around the ankle permits the talus to move in a non-physiologic pattern. Under such circumstances, the dynamic joint surface contact area within the ankle is diminished, which predisposes to articular cartilage damage and premature degeneration. In today’s time, many modalities are available for surgical fixation of bimalleolar fractures. Such interventions restore anatomy and biomechanics of the ankle joint. Even though there are plethora of foreign studies on similar matter, deficiency of such analysis has been depicted in literature from developing countries, particularly from South-East Asian region. In this study, we wanted to assess various methods of internal fixation in ankle fracture &amp; evaluate their clinical and radiological outcome post-operatively. METHODS 26 ankle fracture patients in the age group of 18 - 60 years were included in this study. Fractures were classified pre-operatively based on Lauge-Hansen classification. Patients were followed up at regular intervals of 1st, 2nd, 3rd, 6th &amp; 12 month after surgery and assessed by Baird and Jackson scoring system based on subjective, objective and radiographic criteria. Complications like infection, arthritis, stiffness &amp; implant failure were assessed on regular follow-up. RESULTS Variety of methods (including k-wires, plates &amp; screws) were used for surgical fixation. Majority of fractures resulted from road traffic accident (RTA). Patients were evaluated using Baird &amp; Jackson scoring system during follow-up at 1st, 2nd , 3 rd, 6th &amp; 12 month. All patients had poor scores for initial 3 months. Patients showed good to excellent result on final follow-up at 9 to 12 months after surgery. Complications were observed in 19 % cases with arthritis being most common. CONCLUSIONS Open reduction and internal fixation restores the articular congruity of the ankle joint. The operative result was satisfactory with good clinical outcome.

Psychological dysfunction associated with calcaneal fractures

IntroductionThe calcaneus is the most commonly fractured hindfoot bone, accounting for over 60% of all tarsal fractures. The aim of this study was to compare the mechanism of injury and psychological health status in patients presenting with calcaneal fractures to an age- and sex-matched control group with ankle fractures. Patients and methodsThis retrospective study was undertaken within an orthopaedic unit at a tertiary hospital. An electronic medical record chart review was performed to identify eligible patients. Descriptive statistics were used to summarise the demographic and clinical characteristics of the patients. Between-group differences were analysed with the Mann-Whitney U test and Fisher's exact test for continuous and categorical variables, respectively. Multivariable binary logistic regression was used to determine the relationship between fracture type and underlying psychopathology, adjusting for mechanism of injury. ResultsTwo-hundred and fifteen patients met the eligibility criteria for calcaneal fractures and these patients were subsequently matched to 215 ankle fracture patients. Men accounted for 154 (71.6%) of the patients in each group. Over half (51.2%) of all calcaneal fractures were due to an uncontrolled fall above one-metre, as opposed to 26.0% of ankle fractures, p < 0.001. Falling from a standing height was more common in the ankle fracture group, 37 (17.2%) versus 10 (4.7%), p < 0.001. Patients with calcaneal fractures were more likely to have a diagnosed psychological health complaint, 63 (29.3%) versus 32 (14.9%), p < 0.001. Suicidal ideation was significantly more common in the calcaneal fracture group 14 (6.5%) versus 3 (1.4%), p = 0.011. The presence of premorbid psychopathology was associated with calcaneal fracture, after adjusting for mechanism of injury (odds ratio 2.20, 95% confidence interval 1.32 to 3.65, p = 0.003). ConclusionCalcaneal and ankle fractures display differences in both the mechanism of injury and the history of psychological health conditions. However, after adjusting for the mechanism of injury, diagnosed premorbid psychopathology remains twice as likely in someone with a calcaneal fracture as opposed to an ankle fracture. It may be prudent for orthopaedic surgeons to consider further investigations of psychological health when managing patients with a calcaneal fracture.

Impact of compression stockings on wound healing and complications in ankle fractures: A retrospective cohort study

IntroductionAnkle fractures treated with open reduction and internal fixation (ORIF) have a high incidence of wound complications. By reducing oedema, wound complications can, in theory, be minimized. This study investigates the impact of compression stocking (CS) on such complications after treatment with ORIF. MethodsCompression stockings were introduced as a standard postoperative treatment for all ankle fracture patients treated operatively with ORIF on February 1, 2013. Data were retrieved from medical records two years prior to and following the introduction date. The primary outcome was wound healing status after six weeks and secondary outcomes were wound-healing and major complications up to one year after surgery. ResultsIn total, 187 patients were studied, 74 in the CS group and 113 in the control (non-CS) group. Six weeks after the operation, wound-healing problems occurred in 23% and 13% of the patients in the CS group and the non-CS group (p < 0.0001) respectively. In total, 34% and 19% of the patients in the CS group and non-CS group experienced wound-healing complications one year after the operation (p < 0.02) respectively. Furthermore, major complications within one year occurred in 3% and 4% of patients respectively (p < 0.77). ConclusionAn increase in wound-healing complications after six weeks and one year when using CS was found. However, owing to baseline differences in the two groups, it is only possible to caution against the use of CS.

Syndesmosis fixation in supination-external rotation ankle fractures. Long-Term results of a prospective randomised study

BackroundThe clinical relevance and treatment of syndesmosis injury in supination-external rotation (SER) ankle fractures are controversial. MethodsAfter malleolar fixation 24 SER 4 ankle fracture patients with unstable syndesmosis in external rotation stress test were randomised to syndesmosis transfixation with a screw (13 patients) or no fixation (11 patients). Mean follow-up time was 9.7 years (range, 8.9–11.0). The primary outcome measure was the Olerud-Molander Ankle Outcome Score (OMAS). Secondary outcome measures included ankle mortise congruity and degenerative osteoarthritis, 100-mm visual analogue scale for function and pain, RAND 36-Item Health Survey, and range of motion. ResultsMean OMAS in the syndesmosis transfixation group was 87.3 (SD 15.5) and in the no-syndesmosis-fixation group 89.0 (SD 16.0) (difference between means 1.8, 95% CI −10.4–14.0, P = 0.76). There were no differences between the two groups in secondary outcome measures. ConclusionWith the numbers available, SER 4 ankle fractures with unstable syndesmosis can be treated with malleolar fixation only, with good to excellent long-term functional outcome.

Opioid Consumption Patterns and Prolonged Opioid Use Among Opioid-Naïve Ankle Fracture Patients.

Previous literature has demonstrated an association between acute opioid exposure and the risk of long-term opioid use. Here, the investigators assess immediate postoperative opioid consumption patterns as well as the incidence of prolonged opioid use among opioid-naïve patients following ankle fracture surgery. Included patients underwent outpatient open reduction and internal fixation of an ankle or tibial plafond fracture over a 1-year period. At patients' first postoperative visit, opioid pills were counted and standardized to the equivalent number of 5-mg oxycodone pills. Prolonged use was defined as filling a prescription for a controlled substance more than 90 days after the index procedure, tracked by the New Jersey Prescription Drug Monitoring Program up to 1 year postoperatively. At the first postoperative visit, 173 patients consumed a median of 24 out of 40 pills prescribed. The initial utilization rate was 60%, and 2736 pills were left unused. In all, 32 (18.7%) patients required a narcotic prescription 90 days after the index procedure. Patients with a self-reported history of depression (P = .11) or diabetes (P = .07) demonstrated marginal correlation with prolonged narcotic use. Our study demonstrated that, on average, patients utilize significantly fewer opioid pills than prescribed and that many patient demographics are not significant predictors of continued long-term use following outpatient ankle fracture surgery. Large variations in consumption rates make it difficult for physicians to accurately prescribe and predict prolonged narcotic use. Level III.

Elevation of Inflammatory Cytokines and Proteins after Intra-Articular Ankle Fracture: A Cross-Sectional Study of 47 Ankle Fracture Patients.

Introduction Intra-articular fractures are the leading etiology for posttraumatic osteoarthritis (PTOA) in the ankle. Elevation of proinflammatory cytokines following intra-articular fracture may lead to synovial catabolism and cartilage degradation. We aimed to compare cytokine levels in injured and healthy ankle joints, examine the longer-term cytokine levels in fractured ankles, and investigate the association between cytokine levels in fractured ankles and plasma. Materials and Methods In this cross-sectional study, synovial fluid (SF) and plasma of forty-seven patients with acute intra-articular ankle fractures and eight patients undergoing implant removal were collected prior to surgery. We determined concentrations of sixteen inflammatory cytokines, two cartilage degradation proteins, and four metabolic proteins and compared the levels in acutely injured ankles with those of the healthy contralateral side or during metal removal. Cytokine levels in injured ankles were also compared to serum cytokine levels. Nonparametric Wilcoxon rank-sum and Spearman tests were used for statistical analysis, and a p value below 0.05 was considered significant. Results Compared to the healthy ankles, the synovial fluid in ankles with acute intra-articular fracture had elevated levels of several proinflammatory cytokines and proteases (IL-1β, IL-2, IL-6, IL-8, IL-12p70, TNF, IFNγ, MMP-1, MMP-3, and MMP-9) and anti-inflammatory cytokines (IL-1RA, IL-4, IL-10, and IL-13). The levels of cartilage degradation products (ACG, CTX-2) and metabolic mediators (TGF-β1 and TGF-β2) were also significantly higher. Synovial concentrations of ACG, IL-12-p70, IFNγ, IL-4, and bFGF correlated with serum levels. While most of the examined synovial cytokines were unchanged after implant removal, IL-4 and IL-6 levels were upregulated. Conclusions We show that an acute ankle fracture is followed by an inflammatory reaction and cartilage degeneration. These data contribute to the current understanding of the protein regulation behind the development of PTOA and is a further step towards supplementing the current surgical treatment. This cross-sectional study was “retrospectively registered” on the 31th October 2017 at ClinicalTrials.gov (NCT03769909). The registration was carried out after inclusion of the first patient and prior to finalization of patient recruitment and statistical analyses: https://clinicaltrials.gov/ct2/show/NCT03769909?term=NCT03769909&draw=2&rank=1.

The Surgical Outcomes of Unstable Ankle Fractures in Patients Aged >65 Years.

Aim:To evaluate the surgical outcomes and complications of patients over 65 years of age, with unstable ankle fractures.Material and Method:The study included 111 patients (73F/38 M) operated on between January 2015 and February 2019 and followed up for a mean of 21.2 months (range, 6-62 months).Demographic characteristics, comorbidities, fracture type, and mechanisms of injury were evaluated. Relationships between postoperative complications and comorbidities were examined. In the postoperative functional evaluations, the AOFAS score was used and pre and postoperative mobilization (eg, use of assistive devices) was assessed.Results:The mean age of the patients was 70.5 ± 6.1 years (range, 65-90 years). The mechanism of trauma was low-energy trauma in 90.1% of the fractures and high-energy trauma in 9.9%. The fractures were formed with a SER injury (supination external rotation) in 83.7% of cases and bimalleolar fractures were seen most frequently (85/111, 76%).Complications developed in 16 (14.4%) patients and a second operation was performed in 11 (9.9%) patients with complications. Plate was removed and debridement was performed in 5 of 6 patients due to wound problems. Nonunion was developed in the medial malleolus in 4 patients. Revision surgery was performed because of implant irritation in 2 patients and early fixation loss in the medial malleolus fracture in one patient. Calcaneotibial arthrodesis was performed in 3 patients because of implant failure and ankle luxation associated with non-union. A correlation was determined between ASA score and DM and complications, but not with osteoporosis. The mean follow-up AOFAS score was 86.7 ± 12.5 (range, 36-100).A total of 94 (84.7%) patients could walk without assistance postoperatively and 92 (82.9%) were able to regain the preoperative level of mobilization.Conclusion:Although surgery can be considered an appropriate treatment option for ankle fractures in patients aged >65 years, care must be taken to prevent potential complications and the necessary precautions must be taken against correctable comorbidities.

An Analysis of Traumatic Ankle Fracture Patients: Does Income Status Influence Access to Acute Orthopaedic Surgical Care?

To evaluate if income status affects the timing of presentation to orthopaedic care, surgical treatment, or continuity of care following a closed ankle fracture. Th is retrospective study identified 434 patients with closed ankle fractures treated with operative fixation from 2014 to 2016. Median income data were extracted using the patients' ZIP codes and data from the U.S. Census Bureau. Lower-income patients presented to the hospital and received surgical treatment significantly later than others. They were also more often uninsured and nonadherent with postoperative weightbearing precautions. Additionally, these patients less frequently sought care on the day of their injury, and they had both shorter inpatient stays and duration of overall follow-up in comparison with others. Socioeconomic status is a vital consideration for improving patient access to acute orthopaedic surgical care. Lower-income patients are more susceptible to multiple time-sensitive delays in their care, and these patients frequently encounter difficulties maintaining appropriate follow-up carex.

Neuromuscular Electrostimulation Device Reduces Preoperative Edema and Accelerates Readiness for Theater in Patients Requiring Open Reduction Internal Fixation for Acute Ankle Fracture

Significant edema manifests as soft tissue swelling that can delay surgery in patients with ankle fractures. Interventions that expedite swelling reduction may yield clinical and economic benefits. This case-control pilot study aimed to assess the ability to recruit ankle fracture patients to a prospective study using a neuromuscular electrostimulation (NMES) device. Device effectiveness, safety, and patient acceptability were also assessed. Prospective evaluation of 20 patients admitted for ankle fracture fixation with the application of NMES device to the skin just below the knee (intervention arm). Participants were matched for baseline demographics and injury descriptors to a historical operative cohort (control arm). The time until the swelling had settled to a level permitting surgery (“readiness for surgery”) was recorded alongside patient tolerability and device acceptance. The mean time until swelling reduced to a level permitting surgery was 1.66 days (NMES) versus 3.66 days (control) (P=0.001). Overall 60% of participants were ready for theater after 2 days of treatment with the NMES device compared with 27% in the control group (P&lt;0.01). Independent health economic modeling of this scenario suggests that the savings associated with this accelerated readiness for theater is £569 per patient. The NMES device is safe and well tolerated by patients with ankle fractures. It is easy to apply, can be worn continuously, and does not restrict patients to their bed space. This study suggests that it is effective in reducing ankle edema and accelerating readiness for theater and may therefore allow earlier surgery and reduced length of stay in this patient group.
