title: [Treatment of type c fractures of the distal radius with volar locking compression plate and radial styloid process plate].
abstract: OBJECTIVE
  To analyze the effectiveness ofvolar locking compression plate (LCP) and radial styloid process plate for the treatment of type C fractures of the distal radius.
  
  
  METHODS
  Between May 2010 and May 2011, 24 cases of type C fractures of the distal radius were treated, including 8 males and 16 females with an average age of 52 years (range, 23-73 years). Injury was caused by falling in 20 cases and by traffic accident in 4 cases. All were fresh closed fractures. The locations were the left side in 15 cases and the right side in 9 cases. According to AO typing, there were 16 cases of type C2 and 8 cases of type C3. The preoperative palmar tilt angle ranged from 60 to 25 degrees (mean, -45.3 degrees); the preoperative ulnar inclination angle ranged from 16 to 13 degrees (mean, 8.2 degrees); and the preoperative radial length shortening was 8-18 mm (mean, 12 mm). The time from injury to operation was 3-10 days (mean, 5.2 days).
  
  
  RESULTS
  All operation incisions healed primarily. All patients were followed up 9-16 months (mean, 13.5 months). The healing time of fracture was 8-12 weeks (mean, 10.2 weeks). The articular surface was smooth and the radial length was recovered. The postoperative palmar tilt angle ranged from 8 to 15 degrees (mean, 12.3 degrees); the postoperative ulnar inclination angle ranged from 18 to 26 degrees (mean, 22.3 degrees). No loss of reduction, refracture, or carpal tunnel syndrome occurred during follow-up. The average range of motion of the wrist was 45.3 degrees (range, 30-70 degrees) in dorsal extension, was 50.2 degrees (range, 26-78 degrees) in palmar flexion, was 13.5 degrees (range, 8-25 degrees) in radial inclination, was 23.6 degrees (range, 15-32 degrees) in ulnar inclination, was 65.7 degrees (range, 35-90 degrees) in pronation, and was 72.5 degrees (range, 20-90 degrees) in supination at last follow-up. According to the wrist function by Gartland-Werley scoring, the results were excellent in 12 cases, good in 8 cases, and fair in 4 cases; and the excellent and good rate was 83.3%.
  
  
  CONCLUSIONS
  Treatment of type C fractures of the distal radius with volar LCP and radial styloid process plate can reconstruct normal anatomic structures and get good functional recovery.
