Exempel på navicular

• However, evidence of navicular degeneration has been established in the fossil record of early horses.

• Cartilage degeneration is common in navicular horses, usually along the flexor surface.

• Each hind limb of the horse runs from the pelvis to the navicular bone.

• The navicular bone in the horse is supported by the distal sesamoidean impar ligament and two collateral sesamoidean ligaments.

• Excess tension can also cause exostoses where the ligaments attach to the navicular bone, giving the bone a canoe shape.

• Tension placed on the ligaments that support the navicular bone.

• The "head of talus" looks forward and medialward; its anterior articular or navicular surface is large, oval, and convex.

• Strictly these should be termed the proximal sesamoid bones whereas the navicular bone should be referred to as the distal sesamoid bone.

• It is caused when the navicular bone temporarily loses its blood supply.

• It most commonly describes an inflammation or degeneration of the navicular bone and its surrounding tissues, usually on the front feet.

• Radiography, nuclear scans and ultrasonography may be necessary to determine soundness with special emphasis placed on the examination of the navicular bone and distal phalanx.

• It is made up by the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals.

• Stress fractures most frequently occur in weight-bearing bones, such as the tibia (bone of the lower leg), metatarsals, and navicular bones (bones of the foot).

• Within the tarsus, it articulates with the calcaneus below and navicular in front within the talocalcaneonavicular joint.

• The term "navicular bone" or "hand navicular bone" was formerly used for the scaphoid bone, one of the carpal bones of the wrist.
