29-406: The popliteus muscle originates from the lateral surface of the lateral condyle of the femur by a rounded tendon. Its fibers pass downward and medially. It inserts onto the posterior surface of tibia , above the soleal line . The popliteus tendon runs beneath the lateral collateral ligament and tendon of biceps femoris . The muscle also runs above the lateral meniscus but has no connection with

58-417: A fully comprehensive account of the anatomical medical understanding available at the time of publication. The explosion of medical knowledge in the 20th century led to a vast expansion of the book, which threatened to collapse under its own weight metaphorically and physically. From the 35th edition onward, increased efforts were made to reverse this trend and keep the book readable by students. Nevertheless,

87-456: A readership of medical students and physicians in mind, especially surgeons . For many decades however, precisely because Gray's textbook became such a classic, successive editors made major efforts to preserve its position as possibly the most authoritative text on the subject in English. Toward this end, a long-term strategy appears to have been to make each edition come close to containing

116-407: Is one of the two projections on the lower extremity of the femur . The other one is the medial condyle . The lateral condyle is the more prominent and is broader both in its front-to-back and transverse diameters. The most common injury to the lateral femoral condyle is an osteochondral fracture combined with a patellar dislocation. The osteochondral fracture occurs on the weight-bearing portion of

145-440: Is the 42nd edition. The more popular 41st edition of Gray's Anatomy was published on 25 September 2015 by Elsevier in both print and online versions, and is the first edition to have enhanced online content including anatomical videos and a bonus Gray's imaging library. The 41st edition also has 24 specially invited online commentaries on contemporary anatomical topics such as advances in electron and fluorescent microscopy ;

174-645: The Anatomy Act of 1832, the two worked for 18 months on what would form the basis of the book. Their work was first published in 1858 by John William Parker in London. It was dedicated by Gray to Sir Benjamin Collins Brodie, 1st Baronet . An imprint of this English first edition was published in the United States in 1859, with slight alterations. Gray prepared a second, revised edition, which

203-1061: The Second American Edition (February 1862); the New Third American from the Fifth English Edition (May 1870); the New American from the Eighth English Edition (July 1878); and the New American from the Tenth English Edition (August 1883). W. W. Keen edited the next two editions, namely: the New American from the Eleventh English Edition (September 1887); and the New American from the Thirteenth English Edition (September 1893). In September 1896, reference to

232-415: The popliteus minor is seen. It originates from the femur on the inner side of the plantaris muscle and inserts into the posterior ligament of the knee-joint. Peroneotibialis, 14% of population. Origin is inner side of the head of the fibula, insertion into the upper end of the oblique line of the tibia, it lies beneath the popliteus. Another variant, the cyamella, is a small sesamoid bone embedded in

261-539: The 14th, 15th and 16th editions. Then the American numbering crept ahead, with the 17th American edition published in 1908, while the 17th British edition was published in 1909. This increased to a three-year gap for the 18th and 19th editions, leading to the 1913 publication of the New American from the Eighteenth English , which brought the numbering back into line. Both 20th editions were then published in

290-479: The 25th (August 1948), 26th (July 1954), 27th (August 1959), 28th (August 1966), and 29th (January 1973). Carmine D. Clemente edited and extensively revised the 30th edition (October 1984). With the sale of Lea & Febiger in 1990, the 30th edition was the last American Edition. Sometimes separate editing efforts with mismatches between British and American edition numbering led to the existence, for many years, of two main "flavours" or "branches" of Gray's Anatomy :

319-425: The 38th edition contained 2,092 pages in large format – the highest page count of any and an increase from the 35th edition, which had 1,471 pages. The 41st edition has 1,584 pages. Newer editions of Gray's Anatomy – and even several recent older ones – are still considered to be the most comprehensive and detailed textbooks on the subject. Despite previous efforts to keep Gray's Anatomy readable by students, when

348-524: The 39th edition acknowledged the validity of both approaches but switched to regional anatomy by popular demand. Older, out-of-copyright editions of the book continue to be reprinted and sold, particularly on the internet. However it is not always clear which (British or American) edition these books are republications of. Many seem to be reprints of the 1901 (probably U.S.) edition. Additionally, there are several sites where various older versions can be read online. Henry Gray wrote Gray's Anatomy with

377-686: The English edition was dropped and it was published as the Fourteenth Edition , edited by Bern B. Gallaudet, F. J. Brockway, and J. P. McMurrich, who also edited the Fifteenth Edition (October 1901). There is also an edition dated 1896 which does still reference the English edition stating it is "A New Edition, Thoroughly Revised by American Authorities, from the thirteenth English Edition" and edited by T. Pickering Pick , F.R.C.S. and published by Lea Brothers & Co., Philadelphia and New York. The Sixteenth Edition (October 1905)

406-502: The J.W. Parker publishing business. This coincided with the publication date of the third British edition of Gray's Anatomy. Successive British editions of Gray's Anatomy continued to be published under the Longman, and more recently Churchill Livingstone / Elsevier imprints, reflecting further changes in ownership of the publishing companies over the years. The full American rights were purchased by Blanchard and Lea, who published

435-470: The U.S. and the British one. This can easily cause misunderstandings and confusion, especially when quoting from or trying to purchase a certain edition. For example, a comparison of publishing histories shows that the American numbering kept roughly apace with the British up until the 16th editions in 1905, with the American editions either acknowledging the English edition, or simply matching the numbering in

464-402: The body the structures are located in – e.g. the anatomy of the bones, blood vessels and nerves, etc. of the upper extremity is described in one place). All editions of Gray's Anatomy previous to the 39th were organized by systemic anatomy (i.e., there were separate sections for the body's entire skeletal system , entire circulatory system and entire nervous system , etc.). The editors of

493-537: The bone back together. Supplementation of buttress screws or a buttress plate is used if the fracture extends to the proximal metaphysis or distal diaphysis.

It has had multiple revised editions, and

522-484: The current edition, the 42nd (October 2020), remains a standard reference, often considered "the doctors' bible ". Earlier editions were called Anatomy: Descriptive and Surgical , Anatomy of the Human Body and Gray's Anatomy: Descriptive and Applied , but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy . The book is widely regarded as an extremely influential work on

551-428: The first of twenty-five distinct American editions of Gray's Anatomy in 1862, and whose company became Lea & Febiger in 1908. Lea & Febiger continued publishing the American editions until the company was sold in 1990. The first American publication was edited by Richard James Dunglison, whose father Robley Dunglison was physician to Thomas Jefferson . Dunglison edited the next four editions. These were:

580-571: The knee and draws it posteriorly during knee flexion to prevent crushing the meniscus between the tibia and femur as the knee flexes. Injury to the Popliteus causes posterolateral rotatory instability of knee. This can be treated with Arthroscopic Popliteus Sling reconstruction using the popliteus portal. [REDACTED] This article incorporates text in the public domain from page 484 of the 20th edition of Gray's Anatomy (1918) Lateral condyle of femur The lateral condyle

609-400: The lateral condyle. Typically, the condyle will fracture (and the patella may dislocate) as a result of severe impaction from activities such as downhill skiing and parachuting. Open reduction and internal fixation surgery is typically used to repair an osteochondral fracture. For a AO Type B1 partial articular fracture of the lateral condyle, interfragmentary lag screws are used to secure

638-429: The meniscus in 45% of the cases, but has strong connection with it in 17.5% of the cases. Therefore, popliteus muscle is extrasynovial, extra-articular, and intracapsular. The popliteus muscle is supplied by the tibial nerve , from spinal roots L5 and S1 . There is sometimes an additional head from the sesamoid bone in the lateral (outer) head of the gastrocnemius muscle . Rarely an additional inconstant muscle;

667-549: The neurovascular bundles of the prostate ; stem cells in regenerative medicine ; the anatomy of facial aging; and technical aspects and applications of diagnostic radiology . The senior editor of this book and accompanying website on ExpertConsult is Professor Susan Standring , who is Emeritus Professor of Anatomy at King's College London . The three most recent editions differ from all previous editions in an important aspect: they present anatomical structures by their regional anatomy (i.e., ordered according to what part of

696-470: The same year (1918). Thereafter, it was the British numbering that pushed ahead, with the 21st British edition in 1920, and the 21st American edition in 1924. This discrepancy continued to increase, so that the 30th British edition was published in 1949, while the 30th and last American edition was published in 1984. The current editions also contain histology , embryology , and pathology subjects that complements anatomical knowledge. The newest edition

725-415: The slight inward rotation of the tibia, which is essential in the early stage of this movement. When the knee is in full extension, the femur slightly medially rotates on the tibia to lock the knee joint in place. Popliteus is often referred to as the "Key" to unlocking the knee since it begins knee flexion by laterally rotating the femur on the tibia. Popliteus is also attached to the lateral meniscus in

754-518: The subject. The English anatomist Henry Gray was born in 1827. He studied the development of the endocrine glands and spleen and in 1853 was appointed Lecturer on Anatomy at St George's Hospital Medical School in London . In 1855, he approached his colleague Henry Vandyke Carter with his idea to produce an inexpensive and accessible anatomy textbook for medical students. Dissecting unclaimed bodies from workhouse and hospital mortuaries through

783-412: The tendon of the popliteus muscle. It is rarely seen in humans, with prevalence rates from 0.57–1.8%, but has been described more often in other primates and certain other animals. The popliteus assists in flexing the leg upon the thigh ; when the leg is flexed, it will rotate the tibia inward. It is especially called into action at the beginning of the act of bending the knee, in as much as it produces

812-838: Was edited by J. C. DaCosta, and the Seventeenth (September 1908) by DaCosta and E. A. Spitzka . Spitzka edited the Eighteenth (Oct. 1910) and Nineteenth (July 1913) editions, and in October 1913, R. Howden edited the New American from the Eighteenth English Edition . The "American" editions then continued with consecutive numbering from the Twentieth onwards, with W. H. Lewis editing the 20th (September. 1918), 21st (August 1924), 22nd (August 1930), 23rd (July 1936), and 24th (May 1942). Charles Mayo Goss edited

841-522: Was published in the United Kingdom in 1860, also by J.W. Parker. However, Gray died the following year, at the age of 34, having contracted smallpox while treating his nephew (who survived). His death had come just three years after the initial publication of his Anatomy Descriptive and Surgical . Even so, the work on his much-praised book was continued by others. Longman 's publication reportedly began in 1863, after their acquisition of
