Abstract

Percutaneous internal fixation of scaphoid fractures allows for more predictable union and less morbidity than cast treatment or open internal fixation. A headless cannulated compression screw (standard Acutrak) is implanted by way of a dorsal percutaneous approach with the aid of fluoroscopy and arthroscopy to confirm screw position and fracture reduction. This technique is indicated in the correction of acute proximal pole fractures, acute waist fractures, and delayed unions that are not associated with avascular necrosis or collapse. The details of this technique are reviewed. In a consecutive series of twenty-seven fractures (seventeen waist fractures and ten proximal pole fractures) treated with arthroscopically assisted dorsal percutaneous fixation, computed tomographic scanning confirmed 100% union at an average of twelve weeks. Eighteen fractures were treated within one month after the injury, and nine were treated more than one month after the injury. In this series, the fractures that were treated early (less than one month after the injury) healed more quickly than those treated later.
