The tendon inserts onto the radial tuberosity over an area of 3 [cm.sup.2].
The footprint of the distal biceps insertion is located on the posteroulnar aspect of the radial tuberosity and occupies approximately one-third of the total area of the tuberosity.
In terms of imaging, radiographs are usually obtained to rule out any associated elbow injuries, and may occasionally show irregularity about the radial tuberosity or avulsion fractures.
Only rarely will irregularities be apparent at the radial tuberosity that suggest an avulsion injury.
It is hypothesized that since the distal biceps inserts onto the posterior ulnar aspect of the radial tuberosity, repair using a one-incision technique would attach the tendon in a more anterior position and may result in loss of supination torque.
A non-anatomic attachment of the distal biceps to the brachialis muscle, as opposed to an anatomic attachment to the radial tuberosity, may result in as high as a 50% loss of supination strength.
