Accessory navicular bone may cause a continuous stretch and stress on the tibialis posterior tendon which can progress to chronic disabling pain and may cause tendon rupture or secondary flat foot deformity; when this occurs this condition is commonly known as accessory navicular syndrome. [4]
Stage 1: Tendon is intact, but damaged. Stage 2: Tendon has ruptured. Foot begins to deform. Stage 3: The foot is significantly deformed. Cartilage begins to degenerate. Stage 4: Ankle joint begins to degenerate. [1] In early stages, patients will describe foot and ankle pain. Swelling will also be present.
The tendon also can become inflamed, causing a painful condition called posterior tibial tendonitis or posterior tibial tendon dysfunction, according to the Cleveland Clinic.
The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. [2] It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. [2] The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. [2]
If non-invasive treatment measures fail, tarsal tunnel release surgery may be recommended. Tarsal tunnel release is a form of a nerve decompression to relieve pressure on the tibial nerve. The incision is made behind the ankle bone and then down towards but not as far as the bottom of foot. The posterior tibial nerve is identified above the ankle.
Tendon transfer surgery is necessary when a certain muscle function is lost because of a nerve injury. If a nerve is injured and cannot be repaired, then the nerve no longer sends signals to certain muscles. Those muscles are paralyzed and their muscle function is lost. Tendon transfer surgery can be used to attempt to replace that function.
Injury to the artery behind the knee, compartment syndrome [3] [4] Types: Anterior, posterior, lateral, medial, rotatory [4] Causes: Trauma [3] Diagnostic method: Based on history of the injury and physical examination, supported by medical imaging [5] [2] Differential diagnosis: Femur fracture, tibial fracture, patellar dislocation, ACL tear ...
A tendon transfer is a surgical process in which the insertion of a tendon is moved, but the origin remains in the same location. Tendon transfer involves redistribution of muscle power, not recreation. Tendons are transferred at the distal attachment from lesser to more important functions so that the overall function is improved.
