Stress fractures of the foot are sometimes called "march fractures" because of the injury's prevalence among heavily marching soldiers. [2] Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula (bones of the lower leg), metatarsal and navicular bones (bones of the foot).
The fracture is usually a hairline fracture, commonly missed on normal X-rays. Symptoms are pain aggravated by gripping, tenderness over the hamate and symptoms of irritation of the ulnar nerve. This is characterized by numbness and weakness of the fifth digit with partial involvement of the fourth digit as well, the "ulnar 1½ fingers".
Low anterior hairline is a dysmorphic feature in which the frontal hairline which defines the top and sides of the forehead is unusually low. This can mean that either the distance between the trichion (hairline) and glabella at the midline is more than 2 SD below the mean, or that this distance is apparently (subjectively) decreased. [1] [2] [3]
High anterior hairline is a dysmorphic feature in which the frontal hairline which defines the top and sides of the forehead is unusually high. This can mean that either the distance between the trichion (hairline) and glabella is more than 2 SD above the mean, or that this distance is apparently (subjectively) increased.
Lidström classification is a system of categorizing fractures of the distal radius, one of the two bones of the forearm. In the Lidström classification system there are six types of fractures . The classification system is based on fracture line, direction and degree of displacement, extent of articular involvement and involvement of the ...

[2] Pelvic fractures make up around 3% of adult fractures. [1] Stable fractures generally have a good outcome. [1] The risk of death with an unstable fracture is about 15%, while those who also have low blood pressure have a risk of death approaching 50%. [2] [4] Unstable fractures are often associated with injuries to other parts of the body. [3]
The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [2] [3] The fracture line extends through the zygomatic arch, the pterygoid plates, the lateral and medial orbital walls, the nasal bones, and the nasal septum.
