  • TREATMENT OF TYPE C FRACTURES OF THE DISTAL RADIUS WITH VOLAR LOCKING COMPRESSION PLATE AND RADIAL STYLOID PROCESS PLATE

    Objective To analyze the effectiveness of volar 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° (mean, — 45.3°); the preoperative ulnar inclination angle ranged from — 16 to 13° (mean, 8.2°); 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° (mean, 12.3°); the postoperative ulnar inclination angle ranged from 18 to 26° (mean, 22.3°). No loss of reduction, refracture, or carpal tunnel syndrome occurred during follow-up. The average range of motion of the wrist was 45.3° (range, 30-70°) in dorsal extension, was 50.2° (range, 26-78°) in palmar flexion, was 13.5° (range, 8-25°) in radial inclination, was 23.6° (range, 15-32°) in ulnar inclination, was 65.7° (range, 35-90°) in pronation, and was 72.5° (range, 20-90°) 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%. Conclusion 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.

  • 无头加压螺钉治疗Mason Ⅱ型及Ⅲ型桡骨头骨折

    目的 探讨应用无头加压螺钉治疗Mason Ⅱ型及Ⅲ型桡骨头骨折的疗效。 方法 2009 年5 月-2011 年5 月,采用Acutrak 无头加压螺钉行切开复位内固定治疗18 例Mason Ⅱ、Ⅲ型桡骨头骨折。男10 例,女8 例;年龄25 ~ 62 岁,平均38 岁。损伤原因:摔伤12 例,高处坠落伤4 例,交通事故伤2 例。均为闭合性骨折。伤后至手术时间2 ~ 10 d,平均6.2 d。 结果 术后切口均Ⅰ期愈合。18 例患者均获随访,随访时间6 ~ 18 个月,平均12.3 个月。X线片复查示骨折均愈合,愈合时间8 ~ 12 周;随访期间无桡骨头缺血性坏死发生。末次随访时肘关节功能按照Broberg和Morrey 评分标准:获优12 例,良4 例,可1 例,差1 例,优良率88.9%。 结论 对于Mason Ⅱ型及部分Ⅲ型桡骨头骨折患者采用切开复位无头加压螺钉固定治疗,患者能早期进行功能锻炼,并获满意疗效。

  • Flexible internal fixation with locking plate for distal femoral fractures

    Objective To analyze the effectiveness of flexible internal fixation with locking plate for distal femoral fractures. Methods Between January 2015 and June 2016, 21 cases of distal femoral fractures were treated. There were 5 males and 16 females with an average age of 62 years (range, 32-88 years). Injury was caused by falling in 14 cases, by traffic accident in 5 cases, and by falling from height in 2 cases. The fractures located at the left side in 13 cases and the right side in 8 cases. Twenty cases were fresh closed fractures and 1 case was open fracture. According to AO/Association for the Study of Internal Fixation (AO/OTA) typing, there were 5 cases of type 33-A1, 3 of type 33-A2, 8 of type 33-A3, 2 of type 33-C2, and 3 of type 33-C3. The time from injury to operation was 3-13 days (mean, 6.5 days). Results All operation incisions healed primarily. Eighteen patients were followed up 12-24 months (mean, 16 months). All fractures healed, and the healing time was 8-24 weeks (mean, 16.6 weeks). The articular surface was smooth and the thigh length was recovered. No screw loosening, plate breakage, valgus or varus of the knee, stiff of the knee or non-unions occurred during follow-up. There was no significant difference in visual analogue scale (VAS) score between at 6 and 12 months after operation (P>0.05), and the difference was significant bewteen the other time points (P<0.05). There were significant differences in the range of motion of knee between 1 month and 3, 6, 12 months (P<0.05); there was no significant difference between 3, 6, and 12 months (P>0.05). There were significant differences in the Neer scores between 1, 3, 6, and 12 months after operation (P<0.05). According to Neer score criteria, the results were excellent in 12 cases and good in 6 cases at 12 months after operation. Conclusion Flexible internal fixation with locking plate for distal femoral fractures can get good functional recovery.
