Fracton topological order

Fracton topological order is a three-dimensional topological order in which pointlike fracton excitations are immobile or move only along restricted lines, planes, or fractals, promising for quantum memory.

Fracture

Fracture is the separation of a solid body into pieces under stress. Fracture mechanics predicts the strength of cracked structures from the stress field at the crack tip.

Fracture (2007 film)

Fracture is a 2007 American legal thriller directed by Gregory Hoblit, in which Anthony Hopkins shoots his unfaithful wife and defends himself in court against prosecutor Ryan Gosling.

Fracture (geology)

A fracture, also called a rock fracture, is a break in a rock formed under stress; fractures form interconnected networks that often dominate fluid flow in rock.

Fracture epidemiology and prevention

Fracture epidemiology and prevention is the population-level study of how often fractures occur and who sustains them, plus strategies like fall reduction, exercise, and osteoporosis treatment that lower rates.

Fracture mechanics

Fracture mechanics is the field of engineering science that predicts the behavior of cracks in solids using parameters such as the stress intensity factor, and underpins aircraft damage tolerance analysis.

Fracture of angle of mandible

Fracture of angle of mandible: break at the jaw's angle, the most common mandibular fracture site. Caused by assaults and motor vehicle collisions; highest complication rate of mandibular fractures; treated by miniplate or reconstruction plate fixation.

Fracture of calcaneus

Fracture of calcaneus (heel bone), also called lover's or Don Juan fracture: 1-2% of all fractures, ~75% intra-articular, from axial load falls; surgery aids work return and shoe fit but raises complications.

Fracture of clavicle

Fracture of clavicle (collarbone fracture), ICD-11 NC12.0: a common shoulder girdle injury, 80% midshaft, treated with sling or plate fixation; surgery favored for displaced adult midshaft fractures.

Fracture of coccyx

Fracture of coccyx (tailbone fracture), ICD-11 NB52.11, ICD-10 S32.2: break in the 3-5 fused vertebrae at the spine's base, usually from a backward fall or childbirth; diagnosed clinically, treated conservatively in about 90% of cases, with coccygectomy reserved for refractory pain.

Fracture of cuboid bone

Fracture of the cuboid bone, a rare midfoot injury (about 1.8 per 100,000 annually in the UK), often with Lisfranc or Chopart injuries; nutcracker compression mechanism; surgery if step-off over 1 mm or lateral column shortening over 3 mm.

Fracture of femur

Fracture of femur (broken thigh bone, ICD-11 NC72): break in the femur from hip to knee, classified by site (neck, shaft, distal). Usually needs surgery; children treated by age-based algorithms.

Fracture of fibula

Fracture of fibula (broken calf bone; ICD-11 NC92.4, ICD-10 S82.4). Usually occurs with tibia or ankle fractures; isolated cases rarely need surgery and heal in 6-8 weeks; Weber A-C classify distal fractures.

Fracture of forearm

Fracture of forearm (ICD-11 NC32): break of the radius, ulna, or both. Common in children (74% of upper-limb immature injuries); adults usually need plate fixation, children casting; nonunion in 2–10%.

Fracture of great toe

A fracture of the great toe is a break of a phalanx bone of the hallux, usually from a direct blow, and normally heals without surgery.

Fracture of greater tuberosity of humerus

Fracture of the greater tuberosity of the humerus, a proximal humerus fracture (isolated up to 14–20% of cases, up to 57% of anterior dislocations); surgery usually for displacement over 5 mm, 3 mm in athletes.

Fracture of head of femur

A fracture of the head of the femur is a break in the ball-shaped upper end of the thigh bone, usually with a dislocated hip after high-energy trauma.

Fracture of index finger

Fracture of index finger (ICD-11 NC53.60): a break of one of the three phalanges of the second digit. Diagnosed by AP, lateral, and oblique X-rays; treated with buddy taping or splinting about 3 weeks, surgery for joint involvement, displacement, or rotation; healing 6 to 8 weeks.

Fracture of lateral condyle of humerus

Fracture of the lateral condyle of the humerus, a pediatric elbow fracture (second most common after supracondylar), peaking at age 6; >2 mm displacement requires fixation, with non-union and overgrowth as key complications.

Fracture of lateral malleolus

Fracture of lateral malleolus (ICD-11 NC92.6), a distal fibula fracture classified by Danis-Weber types A, B, C and Lauge-Hansen mechanisms; stability depends on deltoid ligament integrity, and most isolated Weber B fractures can be treated nonoperatively.

Fracture of little finger

Fracture of little finger (ICD-11 NC53.63, 小指の骨折): break of a fifth-digit phalanx or metacarpal. Proximal phalanx most often fractured; boxer's fracture common; POINT trial found splinting equals surgery.

Fracture of lower end of humerus

A fracture of the lower end of humerus, called a distal humerus fracture, is a break in the arm bone forming the upper half of the elbow joint.

Fracture of lower leg, including ankle

Fracture of lower leg, including ankle (ICD-11 NC92): tibia, fibula, malleolar, and complex ankle fractures. About 9% of all fractures; distal fibula most common type; classified by Danis-Weber and Lauge-Hansen; treated by casting or ORIF.

Fracture of lumbar vertebra

Fracture of lumbar vertebra: break of an L1-L5 vertebra, part of thoracolumbar spine injuries (over half of all spinal fractures). Classified by Denis, AO-Magerl, TLICS, and AO Spine systems; operative and nonoperative outcomes similar without deficit.

Fracture of mandible

Fracture of mandible (mandibular fracture), a common facial bone break from assaults or vehicle accidents; treated by closed reduction with maxillomandibular fixation or open reduction with internal fixation, with infection the leading complication.

Fracture of maxilla

Fracture of the maxilla, upper jaw bone injury from midface trauma, classified as Le Fort I, II, III (ICD-11 NA02.4); diagnosed by thin-cut CT, treated by reduction and titanium plate fixation.

Fracture of medial epicondyle of humerus

Fracture of the medial epicondyle of the humerus (ICD-11 NC12.42), a pediatric avulsion elbow fracture from valgus stress; 12–20% of pediatric elbow fractures, often with dislocation; casting noninferior to surgery in randomized trials.

Fracture of medial malleolus

Fracture of medial malleolus (medial malleolar fracture): break of the inner ankle prominence at the lower tibia, usually with other ankle fractures; treated by cast or boot if nondisplaced, screws or plate if displaced.

Fracture of metatarsal bone

Metatarsal fracture, including Jones fracture of the fifth metatarsal, a common midfoot break from trauma or overuse; fifth metatarsal most affected, surgery favored for Jones and zone 3 fractures, conservative care for avulsion and undisplaced shaft fractures.

Fracture of middle finger

Fracture of the middle finger: break of a phalanx of the third digit, usually from direct blow or axial load. Diagnosed by AP, lateral, oblique X-rays; stable fractures get buddy taping, displaced ones reduction and gutter splinting.
