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. Athletes who run, cut and pivot are particularly susceptible to injuries in this area. It is known as the keystone of the foot [10] and injuries to it can be "exasperating." [11]
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.
Fracture of the navicular bone. The tibialis posterior is the only muscle that attaches to the navicular bone. The main portion of the muscle inserts into the tuberosity of the navicular bone. [3] An accessory navicular bone may be present in 2–14% of the general population. [4] [5] [6]
Chopart's fracture–dislocation is a dislocation of the mid-tarsal (talonavicular and calcaneocuboid) joints of the foot, often with associated fractures of the calcaneus, cuboid and navicular. [ 1 ]
A more definitive mapping of fracture zones, including many with no official name, or not meeting the criteria for inclusion on this map, based on the 2015 project of Wessel et al., [1] exists as of 2018. [2]. This page is used on multiple pages and has complex logic so any alteration should be checked as a minor typo can break display on ...
A controlled ankle motion walking boot, also referred to as a controlled ankle movement walking boot, below knee walking boot, CAM boot, CAM walker, or moon boot, is an orthopedic device prescribed for the treatment and stabilization of severe sprains, [3] fractures, and tendon or ligament tears in the ankle or foot.
The name refers to the shape of the bone, supposedly reminiscent of a boat. In older literature about human anatomy, [4] the scaphoid is referred to as the navicular bone of the hand (this time from the Latin navis for boat); there is also a bone in a similar position in the foot, which is called the navicular.
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
