关节镜辅助治疗桡骨远端关节内骨折

Objective To investigate the role of arthroscopy in the treatment of intra-articular distal radius fractures. Methods Twelve cases of intra-articular distal radius fractures treated from 2004 to 2007 were reviewed. In these cases, open reduction and internal fixation were performed with the assistance of wrist arthroscopy to observe the alignment of the articular surface. CT scan was obtained postoperatively to evaluate joint alignment, radial height, volar tilting and radial inclination. Recovery of the wrist function was also followed. Results The average postoperative follow up period was 24 months. None of the 12 cases was found to have any "step" appearance of the articular surface of the wrist. X-ray measurement showed radial height averaged 12 mm (7 to 15 mm), volar tilting averaged 5° (1° to9°) and radial inclination averaged 20 °(14° to28°). Range of motion of the wrist joint achieved 33° of flexion on average ( 18° to 42°) and 38° of extension on average (21° to 42°). Six cases had mild pain during motion. According to Gartland / Werley' s criteria, the result was excellent in 5 eases and good in 7. Conclusion Arthroscope-assisted treatment of intra-articular distal radius fractures can avoid "step" appearance of the articular surface of the wrist, thus achieve maximal functional recovery of the wrist.

非角度稳定性钢板固定治疗桡骨远端关节内背侧移位骨折的结果

Objective Intra-articular fractures of the distal radius in young adults comprise a distinet fracture pattern that is diffficuh to manage and associated with a high frequency of post-traumatic arthritis.Restoration of articular congruency and alignment should improve the outcome.Methods In this study we prospectively re- viewed the results of 21 consecutive cases of dorsally displaced intra-articular distal radius fractures which were treated with internal fixation after failing to achieve articular congruency with closed reduction.Results 3 patients were lost to follow-up.For the rest of 18 patients,follow-up time ranges from 18 to 75 weeks the fractures had healed with highly satisfactory radiographic and functional results.The final volar tilt averaged 4.9°;radial inclination 23.9°;radial length 14mm;and articular incongruity,0.1 mm.Wrist motion at final follow-up examination aver- aged flexion 62°,extension 60°,radial deviation 16°,ulnar deviation 27°,pronation 77°and supination 74°.Grip strength averaged 83% of the uninjured side.The overall outcome of 18 patients(94.4%)had a good or excellent result according to the system of Gartland and Werley and 18 patients(72.2%)had a good result according to the modified system of Green and O'Brien at the most recent evaluation.The only complication in this series was a superficial pin tract infection,which was rapidly resolved with removal of pins at 5th week of external fixation. Conclusion Thus restoration of articular congruency and alignment is possible with minimal complication using modern non-angular stable methods of internal fixation.
