Case control study on the treatment of acromioclavicular dislocation with Endobutton plates combined with an anchor / 中国骨伤

<p><b>OBJECTIVE</b>To compare the clinical effect of Endobutton plates combined with an anchor and clavicle hook plate in the treatment of acromioclavicular dislocation.</p><p><b>METHODS</b>From January 2012 to August 2014, 83 patients with Rockwood type III acromioclavicular dislocation underwent surgical treatments. Among them, 34 patients were treated with Endobutton plate and anchor repair(Endobutton group), including 23 males and 11 females, and the mean age was(39.0±6.3) years old (26 to 51 years old); the average time from injury to operation was(4.1±1.3) days(3 to 7 days);the injured side:14 left, 20 right; the dislocation in 28 patients dues to fall, 6 patients dues traffic accident. There were 49 patients treated with clavicular hook plate(hook plate group), including 33 males and 16 females;the mean age was(37.9±6.3) years old (27 to 53 years old); the average time from injury to operation was(4.1±1.1) days (2 to 7 days);the injured side: 18 left, 31 right;the dislication in 36 patients dues to fall, 13 patients dues traffic accidents. The indexes such as intraoperative bleeding volume, operation time, incision size, postoperative complication and postoperative coracoclavicular space, shoulder joint function, and life quality were compared between two groups.</p><p><b>RESULTS</b>In the hook plate group with 49 patients, the plates in 43 patients were removed at the secondary operation, and 32 patients had shoulder pain or limited active range. Thirty four patients in the Endobutton group had no pain symptoms and limited active range. All the patients did not suffer acromioclavicular dislocation again. There was no significant difference between the two groups in operation time, and intraoperative bleeding volume(>0.05). The incision length in the hook plate group was longer than that in Endobutton group(<0.05). The coracoclavicular space of the uninjured and injured side in two groups respectively had no significant differences, and the coracoclavicular space in the injured side between two group had no significant difference(>0.05). There were no significant differences of Constant score and SF-36 between two groups 2 months after operation(>0.05). Sixteen months after operation, the Constant score in the injured side of both groups was higher than that in 2 months postoperative. But the Constant score in the injured side of hook plate group was higher than that in Endobutton group(<0.05). The Constant score in the uninjured side had no significant differences between two group(>0.05). In hook plate group, the Constant score in the uninjured side was higher than that in the injured side. In Endobutton group, there were no significant differences of Constant score between two sides. The 16 month postoperative SF-36 in the injured side of both groups was higher than the 2 month postoperative one, but 16 month postoperative SF-36 in hook plate group was lower than that in Endobutton group (<0.05).</p><p><b>CONCLUSIONS</b>Endobutton plate combined with an anchor can effectively fix Rockwood type III or more acute acromioclavicular dislocation. The method has less complications, avoiding secondary removal of internal fixation.</p>

Comparative study of three Endobutton plates and clavicular hook plate in the treatment of acromioclavicular joint dislocation / 中国医师进修杂志

Objective To compare the clinical effect of three Endobutton plates and clavicular hook plate in treatment of acromioclavicular joint dislocation.Methods Forty-two patients with acromioclavicular joint dislocation were randomly divided into EB group (20 patients) who were treated with three Endobutton plates and CH group (22 patients) who were treated with clavicular hook plate from January 2008 to January 2011.Perioperative index (operation time,blood loss and VAS scores on the third day postoperatively),Karlsson shoulder joint function scores and postoperative complication were compared.Results The operation time and blood loss in EB group were significantly higher than those in CH group [(113.6 ± 25.3)minvs.(62.3±17.8)min,(152.7±15.2) mlvs.(93.1±18.9)ml,P＜0.O5].However,therehadno significant difference for VAS scores on the third day postoperatively between two groups (P ＞ 0.05).EB group was superior to CH group for shoulder joint function scores on the twelfth month postoperatively,but there had no significant difference [95.0％ (19/20) vs.81.8％ (18/22),P ＞ 0.05].The incidence rate of shoulder joint pain and stiffness in EB group were significant lower than those in CH group[20.0 ％ (4/20) vs.50.0％(11/22),20.0％(4/20) vs.54.5％(12/22),P ＜ 0.05].The incidence rate of incision infection in two groups had no significant difference (P ＞ 0.05).Conclusions Compared with clavicular hook plate,three Endobutton plates fixation is complex and consequently with more blood loss.However,three Endobutton plates fixation have advantage in clinical effect and complication.

Treatment of Acromioclavicular Joint Injuries Using Clavicle Hook Plates

PURPOSE: To analyze results of treating acromioclavicular injuries using clavicle hook plates. MATERIALS AND METHODS: Between February 2008 and April 2010, 18 patients with acromioclavicular joint injury treated by clavicle hook plates were reviewed. Using the Rockwood classification, 7 dislocations were classified as type III injuries and 11 as type V injuries. Implant removal was done at least 3 months from initial fixation. Simple X-rays were taken for comparing the state of reduction, and clinical outcomes were evaluated by the Korean Shoulder Scoring System and the American Shoulder Elbow Society score. The average follow-up period was 9 months. RESULTS: On weight bearing X-rays, the average coracoclavicular distance showed a 114% increase compared to the contralateral side at the time of injury. It decreased to 23% by the last follow-up. The mean Korean Shoulder Scoring System and the American Shoulder Elbow Society score were 80 and 74 at the last follow-up. CONCLUSION: The immediate stability these plates provide allows rapid rehabilitation. Clavicle hook plate fixation for acromioclavicular joint dislocation is considered an effective method for ensuring satisfactory results both radiologically and clinically.
