Bicipitoradial Bursa

From WikiSM
(Redirected from Bicipitoradial bursa)

Description

Diagram shows the position of the bicipitoradial bursa during pronation and supination. With pronation, the interval between the radius and ulna is decreased, resulting in increased intrabursal pressure.[1]
Elbow bursae. a Lateral elbow and b transverse section distal to the elbow joint show bicipitoradial bursa (arrows) and olecranon bursa (curved arrow). Note the brachialis (white area anterior to ulna). B biceps brachii, O olecranon, RT radial tuberosity, U ulna, R radius[2]

Name

  • Bicipitoradial Bursa
  • Bicipital Radial Bursa
  • Cubital Bursa

General

  • Located between the distal biceps tendon anteriorly and the radial tuberosity posteriorly[3]
  • Lies along the medial cortex of the radius, partially envelops the distal biceps tendon
  • Occasionally it ensheaths the tendon[4]

Dimensions

  • Range from 2.4 to 3.9 cm[5]
  • Mean volume of 4 mL

Function

  • Role: reduce friction between distal biceps tendon, proximal radius during pronation and supination
  • Enlargement can impair flexion/ extension of elbow, compress neurovascular structures
  • May compress superficial or deep branches of the radial nerve causing sensory or motor symptoms, respectively
