The middle third of the bone lacks blood vessel penetration and it bears the majority of the load applied to the tarsal bones during weight bearing. Its vascular and biomechanical properties make it susceptible to injury. This may partly explain a higher risk of stress fractures and osteonecrosis in this location.
To diagnose accessory navicular syndrome, the foot and ankle surgeon will ask about symptoms and examine the foot, looking for skin irritation or swelling. The doctor may press on the bony prominence to assess the area for discomfort. Foot structure, muscle strength, joint motion and the way the patient walks may also be evaluated.
[2] [3] Dr. A. Köhler noted that children with foot pain displayed characteristics, within their x-rays, of irregularity in growth and development of the tarsal navicular bone in the foot. Furthermore, Köhler disease is known to affect five times more boys than girls and typically, only one foot is affected.
A Lisfranc injury, also known as Lisfranc fracture, is an injury of the foot in which one or more of the metatarsal bones are displaced from the tarsus. [1] [2]The injury is named after Jacques Lisfranc de St. Martin, a French surgeon and gynecologist who noticed this fracture pattern amongst cavalrymen in 1815, after the War of the Sixth Coalition.
The first mechanism is a stress fracture which happens commonly in athletes, [7] and the other mechanism is a high energy trauma. The navicular bone is a keystone of the foot: it is part of the coxa pedis and articulates with the talus, first, second and third cuneiform, cuboid and calcaneus.
Tarsal coalition is an abnormal connecting bridge of tissue between two normally-separate tarsal (foot) bones, and is considered a sort of birth defect. The term 'coalition' means a coming together of two or more entities to merge into one mass (in the case of bones, see synostosis ). [ 1 ]
Accessory bones of the ankle. [13]Accessory bones at the ankle mainly include: Os subtibiale, with a prevalence of approximately 1%. [14] It is a secondary ossification center of the distal tibia that appears during the first year of life, and which in most people fuses with the shaft at approximately 15 years in females and approximately 17 years in males.
Together, the talus and calcaneus form the hindfoot. [1] The five irregular bones of the midfoot—the cuboid, navicular, and three cuneiform bones—form the arches of the foot which serves as a shock absorber. The midfoot is connected to the hind- and forefoot by muscles and the plantar fascia. [1]
