Introduction

The foot and ankle are vital components of the musculoskeletal system, playing a fundamental role in supporting the body, enabling mobility, and maintaining balance. These complex structures consist of numerous bones, joints, muscles, ligaments, tendons, and nerves, working together to provide stability, flexibility, and propulsion during various activities. Understanding the anatomy, function, and common disorders associated with the foot and ankle is crucial for healthcare professionals involved in the diagnosis and treatment of these conditions. This comprehensive review aims to provide an indepth examination of foot and ankle disorders, covering their anatomy, biomechanics, and prevalent conditions encountered in clinical practice. The foot is composed of 26 bones, divided into three regions: the hindfoot (calcaneus and talus), midfoot (navicular, cuboid, and cuneiforms), and forefoot (metatarsals and phalanges) [1]. These bones form numerous joints, allowing for movement and weight-bearing. Ligaments and tendons provide stability and facilitate coordinated movements. The ankle joint connects the foot to the lower leg and is formed by the articulation between the tibia, fibula, and talus. The foot and ankle function as a complex mechanical system, adapting to various forces and movements during weight-bearing and locomotion. They absorb shock, distribute forces evenly, and provide stability on uneven surfaces. The arches of the foot, including the medial longitudinal, lateral longitudinal, and transverse arches, contribute to weight distribution and support. The muscles and tendons of the foot and ankle generate and control movements, ensuring efficient gait and balance [2-7]. A wide range of disorders can affect the foot and ankle, leading to pain, dysfunction, and impaired quality of life. Some prevalent conditions include plantar fasciitis, Achilles tendonitis, ankle sprains, bunions, Morton's neuroma, flat feet (pes planus), high arches (pes cavus), and osteoarthritis. Each condition has unique clinical features, etiology, and treatment approaches, necessitating a comprehensive understanding for accurate diagnosis and effective management. Accurate diagnosis of foot and ankle disorders relies on a thorough patient history, physical examination, and appropriate imaging studies [8,9]. Clinical assessment includes evaluating pain, range of motion, strength, gait analysis, and specific provocative tests. Imaging techniques such as X-rays, magnetic resonance imaging (MRI), and ultrasound help visualize bony structures, soft tissues, and identify any abnormalities. Treatment options vary depending on the specific condition, ranging from conservative measures such as rest, physical therapy, orthotics, and medications, to surgical interventions when conservative approaches are ineffective or inappropriate [10].

Anatomy of the foot and ankle

Muscles, ligaments, tendons, and nerves that comprise these structures. A comprehensive understanding of the anatomy is essential for identifying specific areas of pathology and understanding the functional implications of various disorders.

Biomechanics and function

The biomechanics and function of the foot and ankle are discussed, highlighting their roles in weight-bearing, shock absorption, propulsion, and balance. The review explores the intricate interaction between bones, joints, and soft tissues during gait and various movements, providing a foundation for understanding the etiology of foot and ankle disorders [11,12].

Common foot and ankle conditions

The review extensively covers common foot and ankle disorders, including but not limited to:

Plantar fasciitis: A condition characterized by inflammation and microtears in the plantar fascia, resulting in heel pain and stiffness.

Achilles tendonitis: Inflammation of the Achilles tendon, typically caused by overuse or repetitive stress, leading to pain and swelling in the back of the ankle.

Ankle sprains: Ligamentous injuries that occur due to excessive stretching or tearing of the ligaments around the ankle joint, often caused by sudden twisting or rolling movements.

Bunions: A deformity of the big toe joint, causing the big toe to deviate towards the other toes, resulting in pain, swelling, and difficulty with footwear.

Morton's neuroma: A painful condition characterized by the thickening of the tissue around the nerves that run between the metatarsal heads, often causing sharp, burning pain in the forefoot.

Flat feet (Pes Planus) and high arches (Pes Cavus): Structural abnormalities of the foot arches that can lead to altered biomechanics and increased risk of various foot and ankle conditions.

Osteoarthritis: Degenerative joint disease that affects the foot and ankle, leading to joint pain, stiffness, and limited mobility.

Diagnosis and treatment

The review outlines the diagnostic approaches used in evaluating foot and ankle disorders, including patient history, physical examination, imaging techniques (such as X-rays, MRI, and ultrasound), and specialized tests. Treatment options, both non-surgical and surgical, are discussed in detail, including conservative measures such as rest, physical therapy, orthotics, medications, and surgical interventions for refractory cases [13-15].
