The foot is a complex part of the human body that contains a large number of bones, joints, and muscles. The two most important joints are the upper and lower ankle joints, with the lower joint further divided into the subtalar and talocalcaneonavicular joints. In addition to the joints, which enable various types of movement, ligaments and muscles assist in stabilizing these joints. The muscles, which are divided into the muscles of the upper side of the foot and the muscles of the sole, actively participate in movement execution. Dorsal and plantar flexion, as well as eversion and inversion, are the possible movements in the foot area. Extraarticular rheumatism refers to a group of inflammatory and degenerative musculoskeletal conditions that cause pain in the soft tissues around the joints. These conditions can affect tendons, tendon attachments, muscles, fascia, bursae, and the joint capsule. Extraarticular rheumatism can be primary (overuse syndromes) or secondary (caused by rheumatic diseases, endocrine disorders, infections, tumors, or medications). Extraarticular rheumatism of the foot includes the following conditions: plantar fasciitis, Achilles tendinopathy, tibialis posterior tendinopathy, peroneal tendinosis, Haglund's syndrome, and Achilles enthesopathy. Pain of varying character is the dominant symptom, accompanied by a restriction in the range of motion of the affected structures. The most important diagnostic step is a thorough history and physical examination. Based on the clinical picture, a diagnosis is made, which can be confirmed by imaging methods if there are uncertainties. Treatment includes physical therapy and medication, and in extreme cases, surgical intervention is required.
