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.
Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula (bones of the lower leg), calcaneus (heel bone), metatarsal and navicular bones (bones of the foot). Less common are stress fractures to the femur, pelvis, sacrum, lumbar spine (lower back), hips, hands, and writs. Stress ...
The first mechanism is a stress fracture which happens commonly in athletes, [7] and the other mechanism is a high energy trauma. New York Jets quarterback Joe Namath broke the navicular bone in his right wrist during a 1970 game vs. the Baltimore Colts , sidelining him for the final nine games of the season.
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.
March fracture is the fracture of the distal third of one of the metatarsal bones occurring because of recurrent stress. It is more common in soldiers, but also occurs in hikers, organists, and other people whose duties entail much standing (such as hospital doctors).
Fractures in the proximal third have a high incidence of AVN (~30%) Waist fractures in the middle third is the most frequent fracture site and has moderate risk of AVN. Fractures in the distal third are rarely complicated by AVN. Non union can also occur from undiagnosed or undertreated scaphoid fractures. Arterial flow to the scaphoid enters ...
[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.
The sinus tarsi located in the hindfoot, it is contained by the calcaneus, talus, talocalcaneonavicular joint, and the bottom of the subtalar joint. [1] There are five ligamentous structures present inside it: the intermediate, medial, and lateral roots of the inferior extensor retinaculum; the cervical ligament, and the interosseous talocalcaneal ligament.
