There is pain originating in the elbow joint from mild to severe which can spread to the rest of the arm. If the bursa is infected, there also will be prominent redness and the skin will feel very warm. Another symptom would include the infected bursa possibly opening spontaneously and draining pus.[25] CausesBursitis normally develops as a result either of a single injury to the elbow (for example, a hard blow to the tip of the elbow), or perhaps more commonly due to repeated minor injuries, such as repeated leaning on the point of the elbow on a hard surface. The chance of developing bursitis is higher if one's job or hobby involves a repetitive movement (for example, tennis, golf, or even repetitive computer work involving leaning on one's elbow).[6] The likelihood of developing the condition is increased as one gets older.[7]As a reaction to injury, the lining of the bursa becomes inflamed. It then secretes a much greater than normal amount of fluid into the closed cavity of the bursa, from where it has nowhere to go. The bursa therefore inflates, producing a swelling over the proximal end of the ulna which is usually inflamed and tender. Another possible cause of inflammation of the bursa is infection, which can usually (but not always) be traced to a crack or other lesion in the skin which allowed for bacteria of the normal skin flora to invade deeper layers of tissue.[8] This bursa is located just over the extensor aspect of the extreme proximal end of the ulna. In common with other bursae, it is impalpable and contains only a very small amount of fluid in its normal state, and fulfills the function of facilitating the joint's movement by enabling anatomical structures to glide more easily over each other. DiagnosisDiagnosis is usually based on symptoms.[4] If there is concern of infection the fluid should be drained and tested.[3] TreatmentsNon-surgical treatmentsConservative management of minor cases involves icing, a compression bandage, and avoidance of the aggravating activity. This can also be augmented with oral or topical anti-inflammatory medications such as NSAIDs. Elbow padding can also be used for symptomatic relief. Treatment for more severe cases may include aspirating the excess bursa fluid with a syringe (draining of the bursa), or injecting into the bursa a hydrocortisone type medication which is aimed at relieving the inflammation and preventing further accumulation of fluid. In case of infection, the bursitis should be treated with an antibiotic.[8] SurgeryIf the fluid continues to return after multiple drainings or the bursa is constantly causing pain, surgery[9] to remove the bursa is an option. The minor operation removes the bursa from the elbow and is left to regrow but at a normal size over a period of ten to fourteen days. It is usually done under general anesthetic and has minimal risks. The surgery does not disturb any muscle, ligament, or joint structures. To recover from surgical removal, a splint will be applied to the arm to protect the skin. Exercises will be prescribed to improve range of motion.[8] References1. ^{{cite book|last1=Ferri|first1=Fred F.|title=Ferri's Clinical Advisor 2018 E-Book: 5 Books in 1|date=2017|publisher=Elsevier Health Sciences|isbn=9780323529570|page=229|url=https://books.google.co.jp/books?id=wGclDwAAQBAJ&pg=PA229-IA5|language=en}} 2. ^1 2 3 4 5 6 7 8 9 10 {{cite journal|last1=Reilly|first1=D|last2=Kamineni|first2=S|title=Olecranon bursitis.|journal=Journal of shoulder and elbow surgery|date=January 2016|volume=25|issue=1|pages=158-67|doi=10.1016/j.jse.2015.08.032|pmid=26577126}} 3. ^1 2 3 4 5 6 7 8 9 {{cite web|title=Elbow (Olecranon) Bursitis|url=https://orthoinfo.aaos.org/en/diseases--conditions/elbow-olecranon-bursitis|website=AAOS|accessdate=19 February 2018}} 4. ^1 2 {{cite web|title=Bursitis - Musculoskeletal and Connective Tissue Disorders|url=https://www.msdmanuals.com/en-jp/professional/musculoskeletal-and-connective-tissue-disorders/bursa,-muscle,-and-tendon-disorders/bursitis|website=MSD Manual Professional Edition|accessdate=19 February 2018|language=en-JP}} 5. ^{{cite journal|last1=Sayegh|first1=ET|last2=Strauch|first2=RJ|title=Treatment of olecranon bursitis: a systematic review.|journal=Archives of orthopaedic and trauma surgery|date=November 2014|volume=134|issue=11|pages=1517-36|doi=10.1007/s00402-014-2088-3|pmid=25234151}} 6. ^NHS direct - Bursitis 7. ^Mayo Clinic - Bursitis risk factors 8. ^1 2 3 {{cite web|url=http://orthoinfo.aaos.org/topic.cfm?topic=a00028 |title=Elbow (Olecranon) Bursitis -OrthoInfo - AAOS |publisher=Orthoinfo.aaos.org |date=2011-01-01 |accessdate=2013-08-19}} 9. ^eOrthopod - Olecranon Bursitis Surgery External links{{Medical resources| DiseasesDB = | ICD10 = {{ICD10|M|70|2|m|70}} | ICD9 = {{ICD9|726.33}} | ICDO = | OMIM = | MedlinePlus = | eMedicineSubj = article | eMedicineTopic = 327951 | MeshID = }}{{Soft tissue disorders}} 3 : Soft tissue disorders|Synovial bursae|RTT |
