BackgroundTalus fractures are often result of high energy mechanisms and can lead to devastating complications. Treatment is often operative; however, the appropriate timing of this has been debated. The purpose of this study is to determine the efficacy and safety of the early treatment of talus fractures.MethodsPatients aged 18 years or older who underwent definitive operative stabilization of their talus fracture at a single urban level 1 trauma center were retrospectively reviewed. Patients were split into 2 groups based on their time to definitive fixation: ≤ or >24 hours. Pertinent demographic, surgical, and follow-up data were collected and analyzed.ResultsA total of 108 fractures were treated with 65 in the ≤24 hours fixation group and 43 in the >24 hours fixation group. Fractures involving the talar neck were the most commonly treated fracture pattern followed by the body and the head. There was no difference between the 2 groups in length to full weight bearing, union, or time to union. Open fracture was found to be the only significant risk factor for nonunion in both groups. There was no significant difference in infection or arthrodesis rates between the 2 groups.ConclusionDefinitive treatment of talus fractures within 24 hours from presentation is both safe and effective with equal outcomes and without increased complications when compared with those injuries that undergo delayed or staged definitive fixation.Level of Evidence:Level III.

BackgroundThe purpose of this study was to perform a comparative analysis of foot and ankle patient education material generated by the AI chatbots, as they compare to the American Orthopaedic Foot and Ankle Society (AOFAS)-recommended patient education website, FootCareMD.org.MethodsChatGPT, Google Bard, and Bing AI were used to generate patient educational materials on 10 of the most common foot and ankle conditions. The content from these AI language model platforms was analyzed and compared with that in FootCareMD.org for accuracy of included information. Accuracy was determined for each of the 10 conditions on a basis of included information regarding background, symptoms, causes, diagnosis, treatments, surgical options, recovery procedures, and risks or preventions.ResultsWhen compared to the reference standard of the AOFAS website FootCareMD.org, the AI language model platforms consistently scored below 60% in accuracy rates in all categories of the articles analyzed. ChatGPT was found to contain an average of 46.2% of key content across all included conditions when compared to FootCareMD.org. Comparatively, Google Bard and Bing AI contained 36.5% and 28.0% of information included on FootCareMD.org, respectively (P < .005).ConclusionPatient education regarding common foot and ankle conditions generated by AI language models provides limited content accuracy across all 3 AI chatbot platforms.Level of Evidence:Level IV.

BackgroundsPlafond-plasty is a joint-preserving procedure to treat varus ankle osteoarthritis (OA) with asymmetrical joint involvement. The aim of this systematic review and meta-analysis was to evaluate indications, different surgical techniques, associated procedures, and results of plafond-plasty in varus ankle OA and to analyze the level of evidence (LOE) and quality of evidence (QOE) of the included studies.MethodsA systematic review of the literature was performed using MEDLINE, Embase, and Cochrane.ResultsFive studies evaluating 99 ankles were included. A non-rigid varus ankle deformity and an ankle OA Takakura stage 3b or less were the most recommended pre-operative indications. Meta-analysis showed a significant post-operative improvement in clinical and radiological parameters. Many associated surgical procedures have been reported, the most frequent being medial additional supramalleolar osteotomy and lateral ankle ligament reconstruction. The level of evidence and methodological quality assessment of the included studies showed an overall low quality.ConclusionPlafond-plasty seems to be a promising surgical option when managing varus ankle OA with asymmetrical joint involvement, extending the indications for joint sparing surgery. Additional associated procedures should be carefully evaluated case-by-case.Levels of Evidence:IV.

Pin tract infections are virtually universal complications with the use of external fixation. While most are superficial and respond to oral antibiotics and local care, septic loosening may occur at the bone-pin interface, which may lead to instability of the fixator, catastrophic failure, fracture, and long-term osteomyelitis. Classification systems and prevention protocols have been developed to address this ubiquitous complication. Treatment of severe pin tract infections often requires debridement, parenteral antibiotics, and removal of the offending pin or the entire external fixator. In cases of osteomyelitic pin tracks, a sizable cavity is often present. We describe a simple technique for treatment of deep bone pin tract infection through the use of debridement, irrigation, and an antibiotic "sparkler," which is a specially prepared percutaneous implant of antibiotic laden bone cement.Levels of Evidence: Level 5.

Background: The aim of this study was to evaluate and compare different fixation methods to achieve Tarsometatarsal joint I (TMT-1) arthrodesis in patients with hallux valgus regarding radiographic correction, complication profile, and clinical outcomes.

Methods: A systematic review and meta-analysis included primary literature results of evidence level 1 to 3 studies in German and English. Inclusion and exclusion criteria were established and applied, along with parameters suitable for comparison of data.

Results: 16 studies with a total of 1176 participants met the inclusion criteria for this analysis. Twelve evaluation criteria were compared among 3 fixation techniques; comprised of a screw-only, dorsomedial plating- and plantar plating cohort. There was no statistical difference in deformity correction (both intermetatarsal- and hallux valgus angle), or AOFAS score between the cohorts. The complication rate was 13% in the plantar-, 19.5% in the dorsomedial-, and 24.5% in the screw cohort. Nonunion was seen in 0.7% of participants in the plantar, 1.4% in the dorsomedial, and 5.3% in the screw group. The time until complete weightbearing correlated positively with the development of nonunion, with a coefficient of 0.376 (P = .009). Hardware removal was performed in 11.8% of patients in the dorsomedial cohort, 7.7% in the screw cohort, and 3.6% in the plantar cohort.

Conclusion: Based on the results of meta-analysis of heterogeneous studies, plantar plating facilitated early weightbearing and patient mobilization compared to the other fixation methods, while carrying the lowest nonunion, hardware removal, and general complication risk. However, owing to the relatively small number of patients in the plantar plating group, more work is necessary to elucidate the benefits of plantar plating for a first tarsometatarsal joint arthrodesis. Development of complications appears to be largely dependent on the fixation model, rather than patient mobilization alone.Level of Evidence: 3.

BackgroundThe incidence of phantom limb pain in patients with Charcot neuroarthropathy who undergo major amputation is not well described. The purpose of this study was to determine whether patients with Charcot neuroarthropathy and diabetes who underwent either a below-knee amputation (BKA) or above-knee amputation (AKA) had an increased rate of phantom limb pain compared with those with a diagnosis of diabetes alone.MethodsUsing international classification of disease (ICD) and common procedural terminology (CPT) codes, the TriNetX research database identified 10 239 patients who underwent BKA and 6122 who underwent AKA between 2012 and 2022. Diabetic patients with and without Charcot neuroarthropathy were compared in terms of demographics and relative risk of developing phantom limb pain after AKA or BKA.ResultsAge, sex, ethnicity, and race did not significantly differ between groups. Charcot neuroarthropathy was associated with significantly increased risk of phantom limb pain following both BKA (risk ratio [RR]: 1.2, 95% confidence interval [CI]: 1.1-1.3, P < .01) and AKA (RR: 1.6, 95% CI: 1.2-2.3, P < .0068).ConclusionOur results indicate that patients with a coexisting diagnosis of Charcot neuroarthropathy who require BKA or AKA may have an increased risk of developing phantom limb pain.Levels of Evidence: Level III.

Despite numerous available agents claiming anti-biofilm properties on wounds, the substantiating evidence remains inconclusive. This study aimed to assess the immediate impact of topical wound treatments on wound biofilm and healing outcomes in acute and chronic ulcers. We comprehensively searched PubMed, ClinicalTrials.gov, and Google Scholar. In addition, eligible gray literature was incorporated. English-language randomized controlled trials (RCTs), observational, cohort, and case-control studies targeting biofilm prevention, inhibition, or elimination across diverse wound types were included. Primary outcomes included biofilm presence and elimination, supplemented by secondary outcomes encompassing reduced wound size, complete closure, and diminished infection indicators. Bacterial load reduction and biofilm presence were also assessed. Twenty-eight articles met the inclusion criteria. Various modalities were identified, including biofilm-visualization techniques, such as wound blotting and handheld autofluorescence imaging. Pooled analysis for the primary outcomes was infeasible due to limited eligible studies and data-reporting challenges. As for the secondary outcomes, the pooled analysis for complete surgical wound closure (2 RCTs, yielding n=284) and presence of surgical site infections/inflammation (2 RCTs, yielding n=284) showed no significant difference, with a log odds ratio (LOD) of 0.58 (95% confidence interval [CI]: -.33, 1.50) and LOD -0.95 (95% CI: -3.54, 1.64; τ² = 2.32, Q = 2.71, P = .10), respectively. Our findings suggest insufficient evidence to support anti-biofilm claims of topical modalities. Clinicians' skill appears to play a pivotal role in biofilm elimination and wound healing enhancement, with potential optimization through visual-guided techniques, such as wound blotting and autofluorescence imaging. More rigorous clinical trials are warranted to ascertain the efficacy of these techniques.Level of Evidence: Therapeutic, 1A.

BackgroundParallax is an imaging phenomenon where an object appears to be at different positions when viewed from different angles. Distortion can occur secondary to internal fluoroscopic, or external environmental, factors. Fluoroscopy is a vital tool to assist surgeons intraoperatively. However, parallax and distortion can lead to inaccuracy, potentially leading to incorrect surgical decisions. The purpose of this study was to investigate the prevalence of parallax/distortion in large fluoroscopy units at a level-1 trauma center.MethodsTwo types of C-arm models were evaluated, including (1) round image intensifiers, and (2) flat plate detectors (FPD). A square plexiglass grid with embedded wire at ½-in intervals was created, with a round metal washer secured centrally. The grid was placed 16 in from the image intensifier. A metal ball bearing (BB) was secured to the center of the x-ray tube. Fluoroscopic images were obtained until the BB and washer were "center-center." A straight blade served as a fiducial marker to ensure there was no off-axis angulation. Standard anterior-posterior and lateral views were obtained. External factors were considered, tested, and limited. Images were printed and the patterns of parallax/distortion were identified.ResultsAll 11/11 (100%) of fluoroscopy units had some degree of parallax and/or distortion. We noted 3 different patterns, including sigmoidal, converging, and diverging. The FPD units had less apparent distortion overall; however, two-thirds (66%) were off-axis in the x- and y-axes in relation to the fiducial marker.ConclusionAll fluoroscopy units had varying degrees and patterns of parallax/distortion. We noted less overall distortion in FPDs. However, some of these units may produce images that are off-axis. This research has important implications for improving the accuracy of intraoperative fluoroscopy. Musculoskeletal surgeons should understand the limitations of fluoroscopy and how to combat parallax distortion to improve surgical outcomes and reduce patient morbidity.Level of Evidence:Level V.

IntroductionThis study analyzes the incidence rate and median workdays missed due to foot and ankle injuries across age groups, sexes, and industries.MethodsWorkplace injury data from 2003 to 2019 were obtained using the Nonfatal Cases Involving Day Away from Work: Selected Characteristics database provided by the Bureau of Labor Statistics (BLS). The data were grouped by injury location (ie, foot, ankle), injury type (ie, fracture, sprain), and industry, and reported with injury incidence rates and median workdays missed.ResultsThe incidence rate of foot and ankle injuries significantly decreased from 2003 to 2019 (P < .001). With increasing age, the incidence rate of foot and ankle injuries decreased (P < .001) and median workdays missed increased (P < .001). Men had significantly higher rates of foot and ankle injuries (P < .001). Agriculture, forestry, fishing, and hunting (foot=10.23%, ankle=10.41%); construction (foot=8.14%, ankle=8.68%); and transportation and warehousing (foot=11.06%, ankle=13.80%) industries had the highest injury incidence rates. Transportation and warehousing (foot=16.8 days, ankle=16.3 days), mining (foot=44.9 days, ankle=17.1 days), and utilities (foot=26.7 days, ankle=24.4 days) industries had the highest median workdays missed.ConclusionIncreased incidence and severity of workplace foot and ankle injuries are associated with male sex and heavy labor industries. Age was positively associated with severity and negatively associated with incidence of workplace ankle injuries.Levels of Evidence:Level III, Retrospective cohort study.

Tibialis anterior tendon (TAT) ruptures are rare, equating to less than 1% of all musculotendinous injuries. These injuries can be acute or atraumatic, with the latter often associated with chronic degenerative tendinopathy. Surgical repair is indicated when conservative measures fail in meeting functional demands. Direct end-to-end repair is the preferred method for TAT ruptures but may not be feasible with a large tendon defect. Various surgical techniques have been described to address this pathology, including allograft tendon interposition or extensor hallucis longus (EHL) transfer. The authors present a unique technique utilizing a minimal incision TAT turn-down with dermal matrix allograft augmentation, and, in addition, a case implementing this technique in a patient with a large insertional defect. The patient's postoperative course and outcomes were favorable, with improvements in pain, satisfaction, functional scores, and strength. The surgical technique offers versatility and can be adapted to different tendon defect sizes. It also allows for minimal-incision exposure, beneficial for patients with comorbidities or compromised skin integrity. In conclusion, the authors present a case report and surgical technique for the management of large-deficit, chronic TAT ruptures using split TAT turn-down. This technique provides a potential solution for cases where direct end-to-end repair is not feasible.Level of Evidence: Level V.
