The increasing number of fixed-angle plate systems used to treat distal radius fractures carries with it the problem of determining the optimal fixation for unstable fractures. Our goal was to analyze the clinical and radiological outcomes of patients with displaced, unstable distal radius fractures treated with a palmar fixed-angle plate.
Design: Prospective protocol; multicenter clinical study; retrospective analysis.
Setting: Level 1 university trauma centers.
Patients: Over a mean 15-month period (range, 12 to 27 months), 141 consecutive patients were treated for an unstable dorsally displaced distal radius fracture of which 114 or 81% were followed for 1 year or longer.
Intervention: Open reduction and palmar internal fixation with a fixed-angle plate (2.4 mm LCP Distal Radius Plates; Synthes, Salzburg, Austria). Indication for surgical treatment was the inability to obtain or maintain fracture or articular alignment after initial closed reduction.
Main Outcome Measures: In a follow-up period, which had to be longer than 12 months, objective and subjective functional results (active range of motion; strength; Disabilities of the Arm, Shoulder, and Hand (DASH) score; visual analog scale (VAS); Green and O'Brien Score) and radiographic assessment (palmar tilt, radial inclination, ulnar variance, fracture union) were assessed. Potentials for complications were given special attention.
Fixation of unstable dorsally displaced distal radius fractures with a fixed angle plate provides sufficient stability with minimal loss of reduction. Nevertheless, very distal palmar plate position can interfere with the flexor tendon system, too long screws can penetrate the extensor compartments, and distal screws in comminuted fracture patterns can cut through the subchondral bone and penetrate into the radiocarpal joint. Mindful of these problems, we consider that the complex fracture pattern of an unstable distal radius fracture cannot be treated by a single plate system and approach.
