Utilization of artificial intelligence in the diagnosis of pes planus and pes cavus with a smartphone camera.

Background: Pes planus (flatfoot) and pes cavus (high arch foot) are common foot deformities, often requiring clinical and radiographic assessment for diagnosis and potential subsequent management. Traditional diagnostic methods, while effective, pose limitations such as cost, radiation exposure, and accessibility, particularly in underserved areas.

Aim: To develop deep learning algorithms that detect and classify such deformities using smartphone cameras.

Congruent Weber-B ankle fractures do not alter tibiotalar contact mechanics.

Current treatment strategy for managing Weber B ankle fractures is mainly governed by mortise congruency, malleolar alignment, deltoid ligament competence and fracture stability. While nonoperative treatment has yielded good functional outcomes in satisfactorily aligned stable injuries, a biomechanical rationale is not firmly established. Furthermore, current radiographic analysis is obscured by observer inaccuracy and beam rotation.

Association of Extraosseous Arterial Diameter With Talar Dome Osteochondral Lesions.

Background: Etiology of osteochondral lesions of the talus (OLT) is multifactorial and may develop from trauma, genetics, or hypovascularity. The talar dome is supplied by the posterior tibial artery (PTA) and, to a lesser degree, the sinus tarsi artery (STA). The role of talar dome hypovascularity on OLT remains poorly studied.

Open ankle fractures in the elderly: predisposing factors and the associated mortality.

The purpose of this study was to investigate the independent effect of open ankle fractures on postoperative mortality and to identify factors leading to open ankle fractures in the elderly population. This is a retrospective case-control study of 1,045 patients aged 65 years and older, with ankle fractures undergoing surgical fixation between 2010 and 2020 at three medical centers (Levels 1-2). A logistic regression analysis was used to identify risk factors for open fractures.

The Influence of Patient Characteristics and Social Determinants of Health on Postoperative Complications Following Achilles Tendon Rupture.

Background: The influence of social determinants of health (SDH) on postoperative complications has been investigated in several studies, although correlation with Achilles tendon rupture (ATR) repair remains uninvestigated. SDH encompasses several factors, including insurance status and area-based measurements, including the Area Deprivation Index (ADI) and Social Vulnerability Index (SVI), which ranks neighborhoods by social disadvantage. This study investigated the correlation between patient demographics, SDH, and complications following ATR repair.

Automation improves the efficiency of weightbearing CT scan 3D volumetric assessments of the syndesmosis.

Background: Weight-bearing CT (WBCT) 3D volumetric measurement has shown promising accuracy for the diagnosis of syndesmotic instability. However, these measurements are rather complex and time-consuming, rendering them a clinically unfavorable option. We hypothesized that automatized measurements would be more accurate and time-efficient than manual ones.

Gender Differences in Achilles Tendon Ruptures-A Retrospective Study and a Review of the Literature.

Achilles tendon ruptures are common injuries typically sustained during sport with higher incidence in men, though little is understood regarding sex-specific risk factors or outcomes following injury management. This cross-sectional clinical study and systematic review aimed to examine sex-specific Achilles tendon rupture incidence and outcomes following intervention. This study included patients who sustained a rupture between 2011-2021, were ≥18 years old, and who had a minimum follow-up of at least six months, and evaluated age, sex, sport involvement, mechanism of injury, and postoperative complications and revision.

Normative contact mechanics of the ankle Joint: Quantitative assessment utilizing bilateral weightbearing CT.

Alterations in ankle's articular contact mechanics serve as one of the fundamental causes of significant pathology. Nevertheless, computationally intensive algorithms and lack of bilateral weightbearing imaging have rendered it difficult to investigate the normative articular contact stress and side-to-side differences. The aims of our study were two-fold: 1) to determine and quantify the presence of side-to-side contact differences in healthy ankles and 2) to establish normative ranges for articular ankle contact parameters.

Critical Portions of a Foot or Ankle Surgical Procedure From Patient and Surgeon Perspectives.

Background: Over the past decade, overlapping procedures in orthopaedic surgery have come under increased public scrutiny. Central to this discussion is what should constitute a "critical portion" of any surgical procedure-a definition which may differ between patients and surgeons. This study therefore aimed to assess which components of three common foot and ankle procedures are considered "critical" from both the patient and surgeon perspectives.

Factors Associated With Symptom Recurrence After Surgical Treatment of Interdigital Neuroma: A Retrospective Chart Review of 127 Patients.

Introduction: Interdigital neuroma (IN) is a benign enlargement of tissue surrounding the common plantar digital nerve. Although the standard surgical treatment of IN remains debated, recent attention has been given to less-invasive surgical decompression by intermetatarsal ligament (IML) release with neurolysis. This study aimed to compare the outcomes of IML release with neurolysis with standard interdigital neurectomy.

Using machine learning in the prediction of symptomatic venous thromboembolism following ankle fracture.

Background: Venous thromboembolism (VTE) is a major cause of morbidity and mortality in the trauma setting, and both prediction and prevention of VTE have long been a concern for healthcare providers in orthopedic surgery. The purpose of this study was to evaluate the use of novel statistical analysis and machine-learning in predicting the risk of VTE and the usefulness of prophylaxis following ankle fractures.

Methods: The medical profiles of 16,421 patients with ankle fractures were screened retrospectively for symptomatic VTE.

Correlation Between Statin Use and Symptomatic Venous Thromboembolism Incidence in Patients With Ankle Fracture: A Machine Learning Approach.

Background: Identifying factors that correlate with the incidence of venous thromboembolism (VTE) has the potential to improve VTE prevention and positively influence decision-making regarding prophylaxis. In this study, we aimed to investigate the correlation between statin consumption and the incidence of VTE in patients who sustained an ankle fracture.

Methods: In this retrospective, case-controlled study, cases were those who developed VTE and controls were those who had no VTE, and the ratio was 1:4.

Comparison between achilles tendon reinsertion and dorsal closing wedge calcaneal osteotomy for the treatment of insertional achilles tendinopathy: A meta-analysis.

Background: The debridement and Achilles tendon reinsertion (DATR) have been the most common surgical approach for the treatment of Insertional Achilles Tendinopathy (IAT), while dorsal closing wedge calcaneal osteotomy (DCWCO) has recently gained popularity as an alternative surgical option. This study aimed to systematically review the published literature on both surgical techniques and compare their clinical outcomes and complication rates.

Methods: A systematic review was performed according to the PRISMA guidelines using Medline, Embase, and Scopus databases.

The use of deep learning enables high diagnostic accuracy in detecting syndesmotic instability on weight-bearing CT scanning.

Purpose: Delayed diagnosis of syndesmosis instability can lead to significant morbidity and accelerated arthritic change in the ankle joint. Weight-bearing computed tomography (WBCT) has shown promising potential for early and reliable detection of isolated syndesmotic instability using 3D volumetric measurements. While these measurements have been reported to be highly accurate, they are also experience-dependent, time-consuming, and need a particular 3D measurement software tool that leads the clinicians to still show more interest in the conventional diagnostic methods for syndesmotic instability.

Talonavicular Osteochondral Lesions: Surgical Technique and Clinical Outcomes from the Boston and Amsterdam Perspectives.

Purpose: The primary purpose of the present study was to assess the patient-reported outcomes, complications, and reoperation rate of patient who underwent surgical treatment for symptomatic osteochondral lesions of the talonavicular joint (TNJ).

Methods: Patients undergoing surgical treatment for symptomatic osteochondral lesions of the TNJ with a minimum of 12-month follow-up were included. Outcomes included clinical patient-reported outcome measures (PROMs), return to sports and work outcomes, and postoperative complications or reoperations.

Implementing automated 3D measurements to quantify reference values and side-to-side differences in the ankle syndesmosis.

Detection of syndesmotic ankle instability remains challenging in clinical practice due to the limitations of two-dimensional (2D) measurements. The transition to automated three-dimensional (3D) measurement techniques is on the verge of a breakthrough but normative and side-to-side comparative data are missing. Therefore, our study aim was two-fold: (1) to establish 3D anatomical reference values of the ankle syndesmosis based on automated measurements and (2) to determine to what extent the ankle syndesmosis is symmetric across all 3D measurements.

Evaluating and Comparing the Correlation and Performance of PROMIS and FAAM ADL in a Foot and Ankle Patient Population.

Background: There is a paucity of literature assessing 2 of the commonly used static Patient-Reported Outcomes Measurement Information System (PROMIS) forms (PROMIS Global-10 and PROMIS Physical Function Short Form 10a [PF SF 10a]) and the Foot and Ankle Ability Measure Activities of Daily Living (FAAM ADL).

Methods: The PROMIS Global-10, PROMIS PF SF 10a, and FAAM ADL were compared among new foot and ankle patients. Spearman rho (ρ) correlations were calculated, and ceiling and floor effects were determined.

Republication of "Stress Fractures of the Foot and Ankle in Athletes".

Stress fractures of the foot and ankle are common injuries in athletes. Management differs considerably based on fracture location and predisposing factors. Repetitive loading of the foot and ankle in athletes should result in physiologic bone remodeling in accordance with Wolff's law.

The effects of perspective taking primes on the social tuning of explicit and implicit views toward gender and race.

The current research aims to investigate whether perspective taking influences social tuning, or the alignment of one's self-views, explicit attitudes, and/or implicit attitudes with those of an interaction partner. In six different experiments, participants believed they would interact with a partner to complete a task. Prior to this ostensible interaction, participants were given a perspective taking mindset prime, or not, and information about their ostensible interaction partners views.

Development and external validation of automated detection, classification, and localization of ankle fractures: inside the black box of a convolutional neural network (CNN).

Purpose: Convolutional neural networks (CNNs) are increasingly being developed for automated fracture detection in orthopaedic trauma surgery. Studies to date, however, are limited to providing classification based on the entire image-and only produce heatmaps for approximate fracture localization instead of delineating exact fracture morphology. Therefore, we aimed to answer (1) what is the performance of a CNN that detects, classifies, localizes, and segments an ankle fracture, and (2) would this be externally valid?

Methods: The training set included 326 isolated fibula fractures and 423 non-fracture radiographs.
