OBJECTIVE: To assess the risk of soft-tissue injury during percutaneous placement of external fixation pins in the proximal radius.
DESIGN: An anatomic study with embalmed cadaver limbs.
SETTING: Hand and upper limb centre at a university-affiliated hospital.
INTERVENTIONS: Two 4-mm Hoffman half pins were percutaneously placed along the dorsoradial ridge of the radius, four finger breadths proximal to the radial styloid process.
MAIN OUTCOME MEASURES: Injuries to soft tissues including tendons, nerves and vessels were noted.
RESULTS: Nerve or tendon injuries occurred in 7 of 26 forearms. Three pins transfixed either the superficial branch of the radial nerve or lateral antebrachial cutaneous nerves. Tendon injuries included the brachioradialis in two forearms, the extensor carpi radialis brevis in three forearms, and the extensor carpi radialis longus and the abductor pollicis longus in one forearm each.
CONCLUSIONS: Percutaneous pin placement in the distal radius is unsafe. The authors recommend open pin placement for fractures of the distal radius.
