Question Answer
Define BursitisInflammation of small flat sac lined with synovium that reduces friction between tendons and bones.
What is the cause of bursitis?Overuse of structures surrounding that leads to friction and inflammation. Usually secondary to other conditions.
What are the potential contributing factors of bursitis?Muscle imbalances, poor biomechanics, postural dysfunctions, lack of flexibility, potential for infection.
Common locationsShoulder- subacromial/subscapular. Olecranon. Trochanteric, Iliopectineal (between iliopsoas/iliofemoral lig), Ischial (between glute max, ischial tuberosity) Knee (pes anserine/infrapatellar/prepatellar), Retrocalcaneal.
Medical Tx for acute bursitis?Rest, NSAIDs, ultrasound, Ice. Protected, possibly aspirated, stretching/strengthening.
Define Baker's CystSynovial cyst appearing on lateral side of popliteal space. Inability to flex knee fully, bulge/tightness. Usually self limiting in less than 2 years.
Define BunionExcessive bone growth, callus and inflamed/thickened bursa on 1st MTP Joint capsule. Response to joint hypermobility, 1st MTP deviates medially and phalanges deviate laterally.
What are the 2 types of Bursae and the difference between them?Adventitious- developed over time due to friction and pressure in superficial fibrous CT. Synovial- congenitally developed feature that helps reduce friction between two moving structures.
Acute Bursitis SymptomsBursa is compressed/irritated, inflammation/heat/swelling, pain is deep/burning during rest and activity, possible referral, reduced ROM.
Chronic Bursitis SymptomsPain or achiness with activity or direct compression, chronic inflammation, fibrosis, adhesions.
