Supinate the forearm.

Make skin incision beginning just lateral to the biceps brachii tendon and extending down the medial border of brachioradialis up to radial styloid. Open the deep fascia.

This exposes the radial vessels and radial recurrent vessels which are ligated and divided. Now flex the elbow and then retract the brachioradialis, long extensors, and radial nerve laterally to expose the supinator. The supinator is freed from its attachment to medial aspect of radius and reflected laterally thereby protecting the deep branch of radial nerve.

To expose distal aspect of bone separate brachioradialis and flexor carpi radialis. This also exposes the superficial branch of radial nerve and radial vessels. They are retracted medially. Remove the flexor pollicis longus and pronator quadratus from the attachments by stripping subperiosteally to expose the bone.

After surgery reattach the flexor pollicis longus and pronator quadratus to the lateral border of radius via soft tissues.
