Objective:
To study the clinical efficacy and complications of Endobutton titanium plate and clavicle hook plate in the treatment of acromioclavicular dislocation.
Methods:
Total 48 patients with Rockwood Ⅲ to Ⅴ acromioclavicular joint dislocation from March 2015 to May 2019 were retrospectively divided into two groups according to different surgical methods. Among the patients, 23 patients were treated with Endobutton loop titanium plate fixation (observation group), including 15 males and 8 females, ranging in age from 23 to 59 years old, with an average of(36.2±8.1) years old;Rockwood type Ⅲ in 6 cases, type Ⅳ in 11 cases and type Ⅴ in 6 cases. Twenty-five patients were treated with clavicular hook plate(control group), including 17 males and 8 females, ranging in age from 22 to 54 years old, with an average of (34.7±6.4) years old; Rockwood type Ⅲ in 6 cases, type Ⅳ in 14 cases and type Ⅴ in 5 cases. The operation time, intraoperative bleeding, hospitalization time, visual analogue scale (VAS) of pain, Constant-Murley score of shoulder function and postoperative complications were compared between the two groups.
Results:
All the patients were followed up, and the duration ranged from 24 to 51 months, with a mean of (30.5±6.5) months. The amountof bleeding and hospitalization time in the observation group were (71.9±4.0) ml and(8.2±1.6) d respectively;and those in the control group were (97.6±13.4) ml and (12.8±1.2) d respectively. There was significant difference between the two groups (P<0.05). There was no significant difference in operation time between the two groups(P>0.05). The VAS scores of the observation group immediately after operation and 12 months after operation were 4.00±0.39 and 1.58±0.13 respectively, which were statistically significant compared with 7.32±0.43 and 3.09±0.23 in the control group (P<0.05). The Constant-Murley scores of shoulder function in the observation group were 59.65±0.15 and 85.97 ±0.73 immediately and 12 months after operation, which were significantly different from those in the control group 52.77±0.19 and 55.78±0.19(P<0.05). In the observation group, there were 1 case of shoulder pain and 1 case of ectopic ossification; in the control group, there were 1 case of internal fixation failure, 3 cases of acromion impact, 3 cases of shoulder pain and 3 cases of ectopic ossification. There was significant difference between the two groups (P<0.05).
Conclusion:
Compared with clavicular hook plate internal fixation in the treatment of acromioclavicular joint dislocation, Endobutton loop titanium plate internal fixation technology has the advantages of less surgical bleeding, shorter hospitalization time, less postoperative pain, good recovery of shoulder joint function and less complications.
