The common extensor tendon is a tendon that attaches to the lateral epicondyle of the humerus.
Structure
The common extensor tendon serves as the upper attachment (in part) for the superficial muscles that are located on the posterior aspect of the forearm:
- Extensor carpi radialis brevis
- Extensor digitorum
- Extensor digiti minimi
- Extensor carpi ulnaris{{Cite book | edition =fortieth| publisher = Churchill Livingstone | isbn = 978-0-443-06684-9 |last = Standring | first = Susan | title= Gray's Anatomy : The Anatomical Basis of Clinical Practice | location = London |date = 2008}}{{Citation|last1=Borowski|first1=Lauren|title=Chapter 30 - Evaluation and Management of Acute Sprains and Strains|date=2018-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780323462150000306|work=Urgent Care Medicine Secrets|pages=182–186|editor-last=Olympia|editor-first=Robert P.|publisher=Elsevier|language=en|doi=10.1016/b978-0-323-46215-0.00030-6|isbn=978-0-323-46215-0|access-date=2020-11-03|last2=Lintner|first2=Laura|editor2-last=O’Neill|editor2-first=Rory M.|editor3-last=Silvis|editor3-first=Matthew L.|url-access=subscription}}
The tendon of extensor carpi radialis brevis is usually the most major tendon to which the other tendons merge.
Function
The common extensor tendon is the major attachment point for extensor muscles of the forearm. This enables finger extension and aids in forearm supination.
Clinical significance
Lateral elbow pain can be caused by various pathologies of the common extensor tendon.{{Citation|last=Carreiro|first=Jane E|title=Chapter 15 - Orthopedics|date=2009-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780443067389000150|work=An Osteopathic Approach to Children (Second Edition)|pages=243–274|editor-last=Carreiro|editor-first=Jane E|place=Edinburgh|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-443-06738-9.00015-0|isbn=978-0-443-06738-9|access-date=2020-11-03|url-access=subscription}} Overuse injuries can lead to inflammation.{{Citation|last1=Dubin|first1=Andrew|title=13 - History and Physical Examination of the Pain Patient|date=2014-01-01|url=http://www.sciencedirect.com/science/article/pii/B978032308340900013X|work=Practical Management of Pain (Fifth Edition)|pages=151–161.e1|editor-last=Benzon|editor-first=Honorio T.|place=Philadelphia|publisher=Mosby|language=en|doi=10.1016/b978-0-323-08340-9.00013-x|isbn=978-0-323-08340-9|access-date=2020-11-03|last2=Lalani|first2=Irfan|last3=Argoff|first3=Charles E.|editor2-last=Rathmell|editor2-first=James P.|editor3-last=Wu|editor3-first=Christopher L.|editor4-last=Turk|editor4-first=Dennis C.|url-access=subscription}}{{Citation|last=Bestic|first=Joseph M.|title=8 - Magnetic Resonance Imaging of the Elbow|date=2018-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780323341691000085|work=Morrey's the Elbow and its Disorders (Fifth Edition)|pages=93–100|editor-last=Morrey|editor-first=Bernard F.|place=Philadelphia|publisher=Content Repository Only!|language=en|isbn=978-0-323-34169-1|access-date=2020-11-03|editor2-last=Sanchez-Sotelo|editor2-first=Joaquin|editor3-last=Morrey|editor3-first=Mark E.}} Tennis elbow is a common issue with the common extensor tendon.{{Citation|last=Sonnabend|first=David H.|title=Soft Tissue Rheumatic Disease Involving the Shoulder and Elbow |date=2010-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780702033773000020|work=The Musculoskeletal System (Second Edition)|pages=19–31|editor-last=Sambrook|editor-first=Philip|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-7020-3377-3.00002-0|isbn=978-0-7020-3377-3|access-date=2020-11-03|editor2-last=Schrieber|editor2-first=Leslie|editor3-last=Taylor|editor3-first=Thomas|editor4-last=Ellis|editor4-first=Andrew M.|url-access=subscription}}{{Citation|last1=Howard|first1=Thomas M|title=Chapter 8 - Physical Examination of the Elbow|date=2008-01-01|url=http://www.sciencedirect.com/science/article/pii/B9781416031970100084|work=The Sports Medicine Resource Manual|pages=71–78|editor-last=Seidenberg|editor-first=Peter H.|place=Philadelphia|publisher=W.B.
