The paramedian foot is a congenital variant that occurs in the center of the second ossification of the navicular tuberosity of the foot. About 14% of normal people have this variation. Ankle sprains or excessive running and jumping training often damage the parasphenoid bone, causing symptoms that do not heal over time, affecting training and performance improvement, and can affect life in serious cases. Most often seen in running athletes, can occur suddenly during the run, but also can gradually strain generated. The disease is mostly caused by ankle inversion sprains, often covered by lateral ankle ligament injuries, and only after the ligaments have healed is the paraspinatus injury found. Patients often complain of pain at the parapatellar region of the foot (located on the medial side of the foot, a bony prominence can be palpated and pain is evident when pressure is applied), which is aggravated when running and jumping. The pain is aggravated by running and jumping. The pain is also present when walking in more severe cases. The paracarpal region of the foot is prominent, with localized pressure pain, and pain in the paracarpal region when the foot is turned inward with force. Pain when the posterior tibial muscle is exerted and resisted, indicating tendinitis of the posterior tibial tendon. In many cases, there is a combination of flat feet of varying degrees, with the flexor digitorum longus sharing more of the role of lifting the longitudinal arch of the foot, and over time, tendinitis symptoms also develop due to strain. Treatment includes suspension and change of training, local physical therapy, local closure, etc. If the problem does not heal, the paraspinatus can be surgically removed.
