Bicipitoradial bursitis introduction Bicipitoradial bursitis (BRB) is inflammation of the bicipitoradial bursa, which is located in the cubital fossa between the biceps tendon and radial tuberosity. This is a relatively uncommon condition and debate exists on true etiology. Sports medicine providers may have something like this sent to them to possibly aspirate or inject diagnostically and it is important to be familiar with this condition.
Bicipitoradial bursitis (BRB) is a painful and function limiting pathology of the bursal sac that envelopes the distal biceps tendon in the cubital fossa and proximal forearm. BRB is usually a result of chronic overuse (repetitive pronation and supination movements) and may coexist with partial insertional tears of distal biceps tendon. The condition may also result from uncommon causes like chronic infections (such as tuberculosis) , chronic inflammatory conditions (nonspecific/rheumatological/chemical synovitis), and tumor-like conditions (synovial chondromatosis, lipoma arborescens).
Clinically, the condition presents as a painful and tender swelling or fullness in the cubital fossa and weakness and pain during forceful forearm rotations (especially supination). There may be a limitation of range of motion due to the swelling. Neurologic symptoms (parasthesias, radiating pain) may be present if adjacent nerves are inflamed/compressed.
Differential diagnoses include tenosynovitis of the distal biceps tendon, ganglion cysts, begin tumors (lipoma arborescens of bicipitoradial bursa, lipoma, and schwannoma), and malignant tumors (soft-tissue sarcoma).Imaging findings have been shown to accurately rule out these conditions and confirm the diagnosis of bicipitoradial bursitis. However, a histological examination may be necessary. Imaging findings can provide better diagnostic accuracy.
Ultrasonography is the first-line examination for many providers depending on access. It is usually sufficient to make the diagnosis of bicipitoradial bursitis. It shows a collection surrounding the distal biceps.
If you are experiencing symptoms that may be related to bicipitoradial bursitis, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
