【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.
Objective To summarize operative procedure and the effectiveness of open reduction with internal fixation or radial head replacement for the treatment of Essex-Lopresti injury. Methods Between November 2002 and October 2010, 10 patients with Essex-Lopresti injury were treated. There were 8 males and 2 females with a mean age of 36 years (range, 20-56 years). Eight cases were fresh closed fracture within 2 days. According to Mason classification, 5 fracture were typeII, 3 were type III. The other 2 cases were old fracture within 3 months. Wrist joint X-ray revealed that all the patients had distal radioulnar joint dislocation. Open reduction with internal mini-plate or absorbable screw fixation was performed in 5 cases, and radial head replacement in 5 cases; meanwhile, the distal radioulnar joint was reducted and fixed. Results All incisions healed by first intention without infection or bone nonunion. The patients were followed up 7 to 24 months with an average of 14.7 months. The X-ray films showed fracture heal ing at 9-20 weeks (mean, 16.3 weeks); distal radioulnar joint was stable without shortening or shift of proximal radius. According to elbow cl inical evaluation system, the results were excellent in 5 cases, good in 3 cases, and fair in 2 cases. According to wrist cl inical evaluation, the results were excellent in 7 cases, good in 2 cases, and fair in 1 case. All patients had good elbow stabil ity, and recovered quickly. Conclusion Early diagnosis, operation, and functional exercises are important to obtain an excellent result in treating Essex-Lopresti injury.
Objective To explore the operation procedure and effectiveness of terrible triad of the elbow joint. Methods Between October 2006 and June 2010, 11 cases of closed terrible triad of the elbow joint were treated by operation. There were 8 males and 3 females with an average age of 32 years (range, 21-53 years). The mechanism of injury was fall ing from height in 4 cases and traffic accident in 7 cases. The time from injury to admission was 30 minutes to 9 days. According to Regan-Morrey classification for fractures of the ulnar coronoid, there were 5 cases of type I, 5 cases of type II, and 1case of type III; and according to Mason classification for fractures of the radial head, there were 4 cases of type I, 5 cases of type II, and 2 cases of type III. The elbow joint range of motion (ROM) was (63 ± 9)° at flexion and extension, and the forearm ROM was (71 ± 8)° at pronation and supination. All cases underwent reduction and fixation by lateral approach combined with medial approach according to McKeeps operation process. After operation, the affected l imb was immobil ized with plaster at elbow joint flexion of 90° and in forearm neutral position, then passive physical exercises were carried out, and finally active physical exercises were done after removing plaster at 4 weeks. Results All incisions healed by first intention. Eleven cases were followed up 7-27 months (14.5 months on average). The X-ray films showed good reduction, the cl inical heal ing time was 8-19 weeks with an average of 11 weeks. Mild ectopic ossification of the elbow joint occurred in 3 cases at 6 months after operation, mild degenerative change in 1 case at 18 months after operation. At last follow-up, the elbow joint ROM was (103 ± 14)° at flexion and extension, and the forearm ROM was (122 ± 13)° at pronation and supination, showing no significant difference when compared with the values of normal elbow joint (P gt; 0.05) and significant difference when compared with the preoperative values of affected elbow joint (P lt; 0.05). According to Mayo elbow performance score, the results were excellent in 5 cases, good in 5 cases, and fair in 1 case with an excellent and good rate of 90.9%. Conclusion The surgical treatment of terrible triad of the elbow joint can restore sufficiently elbow stabil ity, allow early motion postoperatively, and enhance the functional outcome.
【Abstract】 Objective To evaluate the cl inical effect of excising the radial head, repairing or reconstructing themedial collateral l igament (MCL) in treating comminuted fracture of the radial head accompanying by MCL injury. Methods From September 2000 to April 2006, 18 patients with comminuted fractures of radial head accompanying by MCL injury were treated by excision of the radial head, repair or reconstruction of the MCL. Of them, there were 12 males and 6 females,aged 21 to 57 years. Injury was caused by high fall ing in 10 cases and by traffic accidents in 8 cases. According to Mason classifications,13 fractures were of type Ⅲ and 5 of type Ⅳ . Fifteen cases of fresh fractures were operated within 2 weeks, 3 cases of old fractures at 4, 6, and 14 months after injury respectively. Four cases underwent MCL repair and 14 cases underwent MCL reconstruction. Results All the 18 cases were followed up 1-5 years (mean 3 years ). According to Broberg and Morrey scoring system, 4 patients were rated as excellent, 12 as good, 1 as fair, and 1 as poor. The excellent and good rate was 88.9%.Three patients had l ight pain of elbow, 1 patient had moderate pain and the other 14 had no pain. The range of elbow motion was from 110 to 140°(mean 130°). The pronation averaged 75° (35-85°). The supination averaged 80° (65-89°). Compared with normal l imbs, the grip strength decreased by 3% to 28% (mean 15%); the extension strength decreased by 8% to 39% (mean 30%); the flexion strength decreased by 7% to 29% (mean 18%); the pronation strength decreased by 7% to 31% (mean 20%);the supination strength decreased by 15% to 45% (mean 25%). The X-ray films showed that carrying angle increased by 0 to 11°(mean 5° ) under two-newton-meter valgus torque. There were significant differences between injured l imbs and normal l imbs (P lt; 0.05). Conclusion The MCL was the primary valgus stabil izer of the elbow. If the radial head replacement could not becarried out, the repair or reconstruction of the medial collateral l igament was effective.
ObjectiveTo investigate the effectiveness of closed reduction and internal fixation with elastic nails in treatment of Mason type Ⅱ radial head fracture in adults.MethodsA clinical data of 28 patients with Mason type Ⅱ radial head fractures between May 2013 and March 2017 was retrospectively analyzed. Thirteen patients were treated with closed reduction and internal fixation with elastic nails (trial group); 15 patients were treated with open reduction and internal fixation with Herbert screws (control group). There was no significant difference in gender, age, cause of injury, side of fracture, and the time from injury to operation between the two groups (P>0.05). The operation time, blood loss, and fluoroscopy times in the two groups were recorded and compared. Postoperative X-ray films were used to evaluate the bone healing, heterotopic ossification, and necrosis of radial head. The effectiveness was evaluated according to Mayo score criteria of the elbow at last follow-up. ResultsAll patients were followed up 12-30 months (mean, 21.9 months). The operation time and blood loss were significantly less in the trial group than in the control group (P<0.05), while the fluoroscopy times significantly increased in the trial group than in the control group (P<0.05). X-ray films showed that all fractures healed with the bone healing time of (2.85±0.69) months in the trial group and (3.35±0.88) months in the control group. There was no significant difference in bone healing time between the two groups (t=1.654, P=0.110). Heterotopic ossification occurred in 2 cases in the control group. At last follow-up, there was no significant difference in the Mayo scores between the trial group (90.6±5.3) and the control group (86.4±7.1) (t=1.750, P=0.092).ConclusionClosed reduction and internal fixation with elastic nails, as a minimally invasive technique, has advantages of short operation time and less bleeding in the treatment of Mason type Ⅱ radial head fracture.
ObjectiveTo explore the clinical significance of anterior median approach combined with lateral approach to the elbow joint in the treatment of terrible triad of the elbow.MethodsWe retrospectively collected the data of 63 cases who used the anterior median approach of the elbow joint combined with the lateral approach (group A, n=36) or the medial and lateral approach of the elbow (group B, n=27) in the treatment of terrible triad of the elbow between March 2014 and July 2019. The operation time, postoperative complications, and postoperative Mayo score of the elbow were compared between the two surgical approaches.ResultsThe operation time of group A and group B was (93.78±7.78) and (106.93±10.35) min, respectively, and the difference was statistically significant (P<0.05). The patients in both groups completed operations successfully, without vascular or nerve injury. All the wounds healed by first intention. No redislocation or reoperation occurred. Ten months after operation, there was no significant difference in the excellence rate of Mayo score of the elbow (83.3% vs. 85.2%) or postoperative complication rate (16.7% vs. 14.8%) between the two groups (P>0.05).ConclusionThe anterior median approach of the elbow joint combined with the lateral approach and the medial and lateral elbow approach for the treatment of terrible triad of the elbow are equivalent to the postoperative elbow function recovery. The operation time of the former is shorter than that of the latter, and the anterior approach reveals the coronal process intuitively and sufficiently. In the case that there is no medial ligament injury, the anterior median approach of the elbow joint combined with the lateral approach can be preferred.
