Pott's Fracture
Pott's fracture, also known as Pott's syndrome I and Dupuytren fracture, is an archaic term loosely applied to a variety of bimalleolar ankle fractures. The injury is caused by a combined abduction external rotation from an eversion force. This action strains the sturdy medial (deltoid) ligament of the ankle, often tearing off the medial malleolus due to its strong attachment. The talus then moves laterally, shearing off the lateral malleolus or, more commonly, breaking the fibula superior to the tibiofibular syndesmosis. If the tibia is carried anteriorly, the posterior margin of the distal end of the tibia is also sheared off by the talus. A fractured fibula in addition to detaching the medial malleolus will tear the tibiofibular syndesmosis.Moore and Agur. Essential Clinical Anatomy. Lippincotts Williams and Wilkins. 2007 The combined fracture of the medial malleolus, lateral malleolus, and the posterior margin of the distal end of the tibia is known as a "trimalleolar fractu ...

Bimalleolar Fracture
A bimalleolar fracture is a fracture of the ankle that involves the lateral malleolus and the medial malleolus. Studies have shown that bimalleolar fractures are more common in women, people over 60 years of age, and patients with existing comorbidities. Treatment Surgical treatment will often be required, usually an Open Reduction Internal Fixation. This involves the surgical reduction, or realignment, of the fracture followed by the implementation of surgical implants to aid in the healing of the fracture. Prognosis According to some studies, patients with bimalleolar fractures had significantly worse function in the ankle one year after surgical treatment. After recovering fully from their fractures, the majority of patients experience little to mild pain and have few restrictions in functionality.

Medial Malleolus
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word ''malleolus'' (), plural ''malleoli'' (), comes from Latin and means "small hammer". (It is cognate with '' mallet''.) Medial malleolus The medial malleolus is found at the foot end of the tibia. The medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process, flattened from without inward - the medial malleolus. * The ''medial surface'' of this process is convex and subcutaneous. * The ''lateral'' or ''articular surface'' is smooth and slightly concave, and articulates with the talus. * The ''ant ...

Talus Bone
The talus (; Latin for ankle or ankle bone), talus bone, astragalus (), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot.Platzer (2004), p 216 The talus has joints with the two bones of the lower leg, the tibia and thinner fibula. These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus. At the foot end, within the tarsus, the talus articulates with the calcaneus (heel bone) below, and with the curved navicular bone in front; together, these foot articulations form the ball-and-socket-shaped talocalcaneonavicular joint. The talus is the second largest of the tarsal bones; it is also one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage. It is also unusual in that it has a retrograde blood supply, i.e. arterial blood enters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Malleolus
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word ''malleolus'' (), plural ''malleoli'' (), comes from Latin and means "small hammer". (It is cognate with '' mallet''.) Medial malleolus The medial malleolus is found at the foot end of the tibia. The medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process, flattened from without inward - the medial malleolus. * The ''medial surface'' of this process is convex and subcutaneous. * The ''lateral'' or ''articular surface'' is smooth and slightly concave, and articulates with the talus. * The ''ant ...

Fibula
The fibula or calf bone is a human leg, leg bone on the Lateral (anatomy), lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the Upper extremity of tibia, head of the tibia, below the knee, knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle, ankle joint. Structure The bone has the following components: * Lateral malleolus * Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint * The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of tibia, lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular synd ...

Syndesmosis
In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses. Types Most fibrous joints are also called "fixed" or "immovable". These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called '' sutures''. In fetal skulls the sutures are wide to allow slight movement during birth. They later become rigid ( synarthrodial). Some of the long bones in the body such as the radius and ulna in the forearm are joined by a '' syndesmosis'' (along the interosseous membrane). Syndemoses are slightly moveable ( amphiarthrodial). The distal tibiofibular joint is another example. A '' gomphosis'' is a joint between the root of a tooth and the socket in the ...

Trimalleolar Fracture
A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior malleolus. The trauma is sometimes accompanied by ligament damage and dislocation. The three aforementioned parts of bone articulate with the talus bone of the foot The foot ( : feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg mad .... Strictly speaking, there are only two malleoli (medial and lateral), but the term trimalleolar is used nevertheless and as such is a misnomer. The trimalleolar fracture is also known as cotton fracture. Treatment Surgical repair using open reduction and internal fixation is generally required, and because there is no lateral restraint of the foot, the ankle cannot bear any w ...

Percivall Pott
Percivall Pott (6 January 1714, in London – 22 December 1788) was an English surgeon, one of the founders of orthopaedics, and the first scientist to demonstrate that a cancer may be caused by an environmental carcinogen. Career He was the son of Percivall Pott senior. His father died when he was a child, but Joseph Wilcocks, Bishop of Rochester, who was a relative of his mother, paid for his education. He served his apprenticeship with Edward Nourse, assistant surgeon to St Bartholomew's Hospital, and in 1736 was admitted to the Barbers' Company and licensed to practice. He became assistant surgeon to St Bartholomew's in 1744 and full surgeon from 1749 till 1787. As the first surgeon of his day in England, excelling even his pupil, John Hunter, on the practical side, Pott introduced various important innovations in procedure, doing much to abolish the extensive use of escharotics and the cautery that was prevalent when he began his career. In 1756, Pott sustained a bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guillaume Dupuytren
Baron Guillaume Dupuytren (; 5 October 1777 – 8 February 1835) was a French anatomist and military surgeon. Although he gained much esteem for treating Napoleon Bonaparte's hemorrhoids, he is best known today for his description of Dupuytren's contracture which is named after him and on which he first operated in 1831 and published—in ''The Lancet'', in 1834. Birth and education Guillaume Dupuytren was born in the town of Pierre-Buffière in the present-day department of Haute-Vienne. He studied medicine in Paris at the newly established École de Médecine and was appointed prosector, by competition, when only eighteen years of age. His early studies were directed chiefly to anatomical pathology. In 1803 he was appointed assistant surgeon at the Hôtel-Dieu and in 1811 he became professor of operative surgery in succession to Raphael Bienvenu Sabatier. In 1816 he was appointed to the Read chair of clinical surgery and became head surgeon at general the Hôtel-Dieu. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
