Maisonneuve Fracture
The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament of the ankle. This type of injury can be difficult to detect. The Maisonneuve fracture is typically a result of excessive, external rotative force being applied to the deltoid and syndesmotic ligaments. Due to this, the Maisonneuve fracture is described as a pronation-external rotation injury according to the Lauge-Hansen classification system.Lauge-Hansen, N. (1950). Fractures of the ankle. II. Combined experimental-surgical and experimental-roentgenologic investigations. Arch Surg. 60(5): 957- 985.' It is also classified as a Type C ankle fracture according to the Danis-Weber classification system.Sproule, J. A., Khalid, M., O’Sullivan, M., & McCabe, J. P. (2004).

Orthopedics
Orthopedic surgery or orthopedics ( alternatively spelt orthopaedics), is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. Etymology Nicholas Andry coined the word in French as ', derived from the Ancient Greek words ὀρθός ''orthos'' ("correct", "straight") and παιδίον ''paidion'' ("child"), and published ''Orthopedie'' (translated as ''Orthopædia: Or the Art of Correcting and Preventing Deformities in Children'') in 1741. The word was assimilated into English as ''orthopædics''; the ligature ''æ'' was common in that era for ''ae'' in Greek- and Latin-based words. As the name implies, the discipline was initially developed with attention to children, but the correction of spinal and bone deformities in all stages of life eventually ...

Medial Ligament Of Talocrural Joint
The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament is composed of 4 fibers: 1. Anterior tibiotalar ligament 2. Tibiocalcaneal ligament 3. Posterior tibiotalar ligament 4. Tibionavicular ligament. It consists of two sets of fibers, superficial and deep. Superficial fibres Of the superficial fibres, * ''tibionavicular'' pass forward to be inserted into the tuberosity of the navicular bone, and immediately behind this they blend with the medial margin of the plantar calcaneonavicular ligament; * ''tibiocalcaneal'' descend almost perpendicularly to be inserted into the whole length of the sustentaculum tali of the calcaneus; * ''posterior tibiotalar'' from the posterior colliculus of the medial malleolus to the posteromedial surface of the talus Deep fibres The deep fibres (''anterior tibiotalar'') are attached from the anterio ...

Superior Tibiofibular Joint
The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior ligaments. When the term ''tibiofibular articulation'' is used without a modifier, it refers to the proximal, not the distal (i.e., inferior) tibiofibular articulation. Clinical significance Injuries to the proximal tibiofibular joint are uncommon and usually associated with other injuries to the lower leg. Dislocations can be classified into the following five types: * Anterolateral dislocation (most common) * Posteromedial dislocation * Superior dislocation (uncommon, associated with shortened tibia fractures or severe ankle injuries) * Inferior dislocation (rare, associated with lengthened tibia fractures or avulsion of the foot, usuall ...

Weight-bearing
In orthopedics, weight-bearing is the amount of weight a patient puts on an injured body part. Generally, it refers to a leg, ankle or foot that has been fractured or upon which surgery has been performed, but the term can also be used to refer to resting on an arm or a wrist. In general, it is described as a percentage of the body weight, because each leg of a healthy person carries the full body weight when walking, in an alternating fashion. After surgery of the hip, or of the bones of the leg, ankle, or foot, it is of the utmost importance for recovery to get the right amount of weight-bearing when moving around with crutches or frames. The grades of weight bearing for each phase of recovery will be determined by the surgeon. The Anti-Gravity Treadmill can allow testing of weight bearing by lowering effective body weight in 1% increments from 100 to 20% of body weight.{{citation needed, date=February 2022 Grades * ''Non-weight-bearing'' (NWB): The leg must not touch the floor ...

Range Of Motion
Range of motion (or ROM), is the linear or angular distance that a moving object may normally travel while properly attached to another. It is also called range of travel (or ROT), particularly when talking about mechanical devices and in mechanical engineering fields. For example, a sound volume control knob. As used in the biomedical field and by weightlifters, range of motion refers to the distance and direction a joint can move between the flexed position and the extended position. The act of attempting to increase this distance through therapeutic exercises (range of motion therapy—stretching from flexion to extension for physiological gain) is also sometimes called range of motion. Measuring range of motion Each specific joint has a normal range of motion that is expressed in degrees. The reference values for the normal ROM in individuals differ slightly depending on age and gender. For example, as an individual ages, they typically lose a small amount of ROM. Analog ...

Pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." In medical diagnosis, pain is regarded as a symptom of an underlying condition. Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Simple ...

Fracture Of Medial Malleolus
Fracture is the separation of an object or material into two or more pieces under the action of stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially, it is called a shear crack, slip band or dislocation. Brittle fractures occur with no apparent deformation before fracture. Ductile fractures occur after visible deformation. Fracture strength, or breaking strength, is the stress when a specimen fails or fractures. The detailed understanding of how a fracture occurs and develops in materials is the object of fracture mechanics. Strength Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture. This is usually determined for a given specimen by a tensile test, which charts the stress–strain cur ...

Avulsion Fracture
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament by the application of forces external to the body (such as a fall or pull) or at the tendon by a muscular contraction that is stronger than the forces holding the bone together. Generally muscular avulsion is prevented by the neurological limitations placed on muscle contractions. Highly trained athletes can overcome this neurological inhibition of strength and produce a much greater force output capable of breaking or avulsing a bone. Types Dental avulsion Traumatic complete displacement of a tooth from its socket in alveolar bone. It is a serious dental emergency in which prompt management (within 20–40 minutes of injury) affects the prognosis of the tooth. Tuberosity avulsion of the 5th metatarsal left, Proximal fractures of 5th metatarsa The tuberosity avulsion fracture (also known as pseud ...

Jules Germain François Maisonneuve
Jules Germain Francois Maisonneuve (10 December 1809 – 9 April 1897) was a French surgeon and student of Guillaume Dupuytren. Maisonneuve is notable as the first surgeon to explain the role of external rotation in the production of ankle fractures. The eponymously named Maisonneuve fracture describes a specific fibular The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below.

Galeazzi Fracture
The Galeazzi fracture is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint. It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint; the injury disrupts the forearm axis joint. Signs and symptoms Pain and soft-tissue swelling are present at the distal-third radial fracture site and at the wrist joint. This injury is confirmed on radiographic evaluation. Forearm trauma may be associated with compartment syndrome. Anterior interosseous nerve (AIN) palsy may also be present, but it is easily missed because there is no sensory component to this finding. A purely motor nerve, the AIN is a division of the median nerve. Injury to the AIN can cause paralysis of the flexor pollicis longus and flexor digitorum profundus muscles to the index finger, resulting in loss of the pinch mechanism between the thumb and index fing ...

Danis–Weber Classification
The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories: ;Type A Fracture of the fibula distal to the syndesmosis (the connection between the distal ends of the tibia The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects ... and fibula). Typical features: * below level of the ankle joint * tibiofibular syndesmosis intact * deltoid ligament intact * medial malleolus occasionally fractured * usually stable: occasionally nonetheless requires an open reduction and internal fixation (ORIF) particularly if medial malleolus fractured ;Type B Fracture of the fibula at the level of the syndesmosis.
