  • ARTHROSCOPIC POKING REDUCTION AND INTERNAL FIXATION OF RADIAL HEAD

    【Abstract】 Objective To investigate the methods and effectiveness of arthroscopic poking reduction and percutaneousfixation of radial head fractures. Methods Between August 2002 and May 2010, 15 patients with radial head fractures weretreated using arthroscopic poking reduction and percutaneous fixation with a Kirschner wire. There were 11 males and 4 females with an average age of 29.6 years (range, 17-41 years). The locations were left side in 6 cases and right side in 9 cases. Injuries were caused by falling in 8 cases, by traffic accident in 4 cases, and by sports in 3 cases. The average time from injury to admission was 3.4 days (range, 1-8 days). Of them, 13 patients had Mason type II, and 2 patients had type III fractures. Accompanying injuries were lateral collateral ligament ruptures in 5 patients. Results The X-ray films confirmed good reduction and fracture heal ing. Incisions healed by first intention; no complication occurred, such as neurovascular injury, infection, or hardware failure. All patients were followed up 25 months on average (range, 12-32 months). The flexion-extension arc was (139.0 ± 7.9)° at last follow-up, showing no significant difference when compared with the contralateral (141.0 ± 5.1)° (t=1.146, P=0.271); the range of pronation and supination was (143.3 ± 7.0)° when compared with the contralateral (146.0 ± 4.7)° (t=1.948, P=0.072). The mean Mayo elbow performance score was 92 (range, 80-100); the mean Broberg-Morrey score was 95.2 (range, 85-100); the results were excellent in 12 cases and good in 3 cases. Conclusion Arthroscopic poking reduction and percutaneous fixation with a Kirschner wire offers accurate reduction, rel iable fixation, minimal trauma, rapid recovery, and lower morbidity for Mason type II and selective Mason type III radial head fractures.

  • EFFECTIVENESS COMPARISON BETWEEN OPEN REDUCTION COMBINED WITH INTERNAL FIXATION AND ARTIFICIAL RADIAL HEAD REPLACEMENT IN TREATING MASON TYPE-III COMMINUTED FRACTURES OF RADIAL HEAD

    To compare the effectiveness between open reduction combined with internal fixation and artificial radial head replacement in treating Mason type-III comminuted fracture of radial head, to provide the evidence for available treatment methods. Methods Between January 2004 and June 2008, 65 cases of Mason type-III comminuted fractures were treated with open reduction, AO mini plate and screw system or a combination of Kirschner treatment (internal fixation group, n=35) and with artificial radial head replacement (replacement group, n=30). In internal fixation group, there were 21 males and 14 females with an age range of 21 to 35 years (mean, 30.7 years); the causes of injury were traffic accidentin 12 cases, fall ing from height in 8 cases, and a fall in 15 cases; the locations were left side in 23 cases and right side in 12 cases; and the time between injury and surgery was 1-7 days (mean, 3 days). In replacement group, there were 19 males and 11 females with an age range of 23 to 67 years (mean, 32.5 years); the causes of injury were traffic accident in 7 cases, fall ing from height in 8 cases, and a fall in 15 cases; the locations were left side in 17 cases and right side in 13 cases; and the time between injury and surgery was 1-6 days (mean, 1.5 days). There was no significant difference in gender, age, disease cause, disease duration, or other general information between 2 groups (P gt; 0.05), so that 2 series of patients had comparabil ity. Results Incisions healed primarily in 2 groups. All patients were followed up 1 to 4 years with an average of 2.5 years. There were significant differences in elbow flexion angle, extension angle, and forearm rotation angle between 2 groups (P lt; 0.05), but no significant difference in elbow pronation or supination weakness (P gt; 0.05). In internal fixation group, primary union occurred in 29 cases, delayed union in 2 cases, nonunion with ectopic ossification in 2 cases, and internal fixation failure in 2 cases. In replacement group, elbow flexion angle lost beyond 30º in 1 case after 1 year, elbow stiffness occurred in 1 case because prosthesis was too long. According to Broberg and Morrey elbow scores system, the scores were 69.51 ± 10.23 in internal fixation group and 81.55 ± 12.06 in replacement group, showing significant difference (P lt; 0.05). The results were excellent in 15 cases, good in 5 cases, fair in 11 cases, and poor in 4 cases with an excellent and good rate of 57.1% in internal fixation group; the results were excellent in17 cases, good in 5 cases, fair in 6 cases, and poor in 2 cases with an excellent and good rate of 73.3%. Conclusion Artificial radial head replacement can achieve better joint function compared with open reduction combined with internal fixation in treating Mason type-III comminuted fractures of radial head.

  • 肘前方入路治疗Mason Ⅱ型桡骨小头骨折合并Regan-Morrey Ⅱ型尺骨冠状突骨折

    目的总结肘关节前方入路治疗MasonⅡ型桡骨小头骨折合并Regan-MorreyⅡ型尺骨冠状突骨折的疗效。 方法2010年1月-2013年6月采用肘关节前方入路、Herbert螺钉内固定治疗8例MasonⅡ型桡骨小头骨折合并Regan-MorreyⅡ型尺骨冠状突骨折患者。男6例,女2例;年龄27~53岁,平均36.4岁。致伤原因:高处坠落伤3例,摔伤5例。受伤至手术时间4~10 d,平均4.6 d。 结果术中无血管、神经损伤,术后手术切口均Ⅰ期愈合。8例患者均获随访,随访时间16~27个月,平均18.6个月。X线片复查示骨折均愈合,愈合时间2~4个月,平均2.8个月;无异位骨化、创伤性骨关节炎等并发症发生。末次随访时,Mayo肘关节功能评分86~95分,平均92.3分;其中优5例,良3例,优良率100%。肘关节屈伸活动范围96~145°,平均128°;前臂旋转活动范围140~170°,平均150°。 结论对于MasonⅡ型桡骨小头骨折合并Regan-MorreyⅡ型尺骨冠状突骨折,采用肘关节前方入路可清晰暴露骨折,Herbert螺钉内固定牢靠,治疗效果满意。
