    AbstractRevision of the treatment rationale for combined fractures of the scaphoid and distal radius is based on evolution of treatment goals. The trend toward early recovery of hand function requires rigid fixation of both fractures before the start ofa hand therapy program. It is clear that prolonged immobilization of the scaphoid fracture jeopardizes early motion protocols for the distal radius. The fixation of unstable distal radius fractures with volar locking plates appears to offer the most stable construct to permit early motion. Evaluation, reduction, and fixation should be accomplished without disruption of the uninjured ligaments required for stable motion or the soft tissue envelope required for healing. Minimally invasive or percutaneous techniques are the meth-ods required. The tools needed are a clear understanding of anatomy, minifluoroscopic imaging units, and small-joint arthroscopy instruments. Many investigators advocate these techniques for scaphoid and distal radius fractures. It is only natural that these techniques should be used for these combined injuries. The key to success is a three-step process: (1)percutaneous reduction of the scaphoid fracture and provisional stabilization with a guide wire placed along its central axis, (2) percutaneous/arthroscopic reduction and rigid fixation of the distal radius fracture to permit early motion, and(3) fixation of the scaphoid fracture. This final step is accomplished by dorsal percutaneous implantation of a cannulated headless compression screw along the central scaphoid axis. Dorsal percutaneous fixation of scaphoid fractures with headless compression screws and rigid fixation of unstable distal radius fractures with a volar lock-ing plate system offer the most secure fixation. This small series suggests that the goals of early recovery of hand function can be accomplished using percutaneous/miniopen techniques for fracture reduction with rigid fixation and minimal risks.
