Background
Whether the percutaneous antegrade technique — placing a small screw across a scaphoid fracture from the back of the wrist through a tiny incision — risks injuring nearby tendons, nerves or blood vessels. We tested this in 40 cadaveric forearms.
Rationale
The scaphoid is a small wrist bone that, when fractured, often heals slowly — or fails to heal at all — if treated in plaster alone. A small screw placed across the fracture line speeds healing and lets the patient return to use of the hand much sooner. The percutaneous (through-the-skin) approach is attractive because it leaves only a tiny scar. But it is performed without seeing the deeper tissues directly, raising questions about whether nearby structures might be at risk.
Results
No nerve or blood vessel injuries occurred in any of the 40 specimens. However, tendons were caught in 5 of the 40 (the long thumb extensor in two, the wrist extensor in two, and a finger extensor in one). The injuries were avoidable: extending the skin incision slightly and dissecting bluntly down to the bone — rather than passing the wire through skin alone — protects the tendons.
Implications
Percutaneous scaphoid screw fixation is a safe and reliable technique when performed with care: a slightly longer incision and gentle blunt dissection make the difference. For patients, the take-away is that the very small scar of a strict “keyhole” technique is not worth a tendon injury — surgeons today use a small but considered approach.
