Introduction

Accurate diagnosis and effective management of foot and ankle conditions rely on comprehensive and advanced diagnostic techniques. Foot and ankle diagnostics encompass a range of assessment methods and imaging modalities that aid in identifying underlying pathologies, determining the extent of injury, and guiding appropriate treatment strategies. In recent years, significant advancements have been made in the field of foot and ankle diagnostics, revolutionizing the way these conditions are assessed and managed [1]. The foot and ankle complex is a highly intricate anatomical region composed of numerous bones, joints, ligaments, tendons, and soft tissues. It is susceptible to various orthopedic and podiatric conditions, including fractures, ligamentous injuries, arthritis, tendon disorders, and deformities. Accurate assessment and early detection of these conditions are essential for initiating timely interventions and improving patient outcomes. Traditionally, the assessment of foot and ankle conditions relied on detailed patient history, physical examination, and functional evaluation [2, 3]. Clinical examination techniques such as inspection, palpation, range of motion assessment, and specific stress tests provide valuable information about pain, swelling, instability, and mechanical abnormalities. Functional assessment tools, including gait analysis and foot pressure measurement systems, help evaluate biomechanical abnormalities and identify gait deviations or pressure points.

While clinical examination remains fundamental, advances in imaging modalities have greatly enhanced the diagnostic capabilities in foot and ankle conditions. Conventional radiography, including X-rays,is routinely employed for initial evaluation due to its cost-effectiveness and ability to assess bony structures. It aids in identifying fractures, joint degeneration, dislocations, and bone deformities. However, limitations arise when evaluating soft tissue pathologies [4-7]. Magnetic resonance imaging (MRI) has emerged as a powerful tool for evaluating soft tissue structures in the foot and ankle. It provides detailed visualization of ligaments, tendons, cartilage, and soft tissue masses. MRI is particularly valuable in diagnosing ligamentous injuries, tendon disorders, osteochondral lesions, and soft tissue tumors. It helps determine the extent of injury, assess joint stability, and guide treatment decisions.

Ultrasonography is another valuable imaging modality for foot and ankle diagnostics. It offers real-time imaging, allowing for dynamic evaluation of tendons, ligaments, and soft tissue structures. Ultrasound is commonly used for diagnosing Achilles tendon pathology, plantar fasciitis, Morton's neuroma, and soft tissue masses [8]. It is also useful for guiding injections and aspirations, facilitating accurate placement and therapeutic delivery.

Computed tomography (CT) provides high-resolution imaging of bony structures, enabling detailed assessment of fractures, complex deformities, and preoperative planning. It is particularly beneficial in assessing the subtalar joint, Lisfranc injuries, and assessing alignment for surgical interventions. Nuclear medicine imaging techniques, such as bone scintigraphy and positron emission tomography (PET), offer functional information and aid in the evaluation of bone and joint infections, as well as identifying areas of increased metabolic activity.

Emerging technologies continue to shape the field of foot and ankle diagnostics. Three-dimensional (3D) imaging techniques, such as 3D CT and cone-beam CT, provide detailed anatomical information, aiding in surgical planning, implant placement, and assessing complex deformities. Infrared thermography offers a non-invasive means of assessing vascular perfusion and identifying areas of inflammation [9-11]. Optical coherence tomography (OCT) enables high-resolution imaging of tissue microstructures and has potential applications in diagnosing and monitoring various foot and ankle conditions. Advanced motion analysis systems employ marker-based or markerless tracking techniques to evaluate joint kinematics and aid in the assessment of foot and ankle function.

In this discussion, we will explore the current trends and advancements in foot and ankle diagnostics and their implications for clinical practice.

Assessment techniques

The assessment of foot and ankle conditions has evolved beyond traditional clinical examination. While physical examination remains a fundamental component, emerging trends focus on objective and quantitative measures. Gait analysis, for example, provides valuable information about the dynamic biomechanics of the foot and ankle during walking or running. Advanced motion analysis systems, utilizing marker-based or markerless tracking techniques, allow for the evaluation of joint kinematics, foot function, and the effects of interventions. These objective measures help in diagnosing gait abnormalities, monitoring treatment progress, and guiding rehabilitation strategies.
