Single coracoclavicular suture fixation with Mersilene tape versus hook plate in the treatment of acute type V acromioclavicular dislocation: a retrospective analysis

The objective of the study is to compare the clinical outcomes of two different interventions for Rockwood type III (or above) acromioclavicular dislocation and study the factors influencing postoperative functional recovery. A total of 60 patients with Rockwood type III (or above) acromioclavicular dislocation were included in the study. Patients were divided into two groups based on the surgical intervention: Clavicular Hook Plate Fixation (Group A) and EndoButton technique of Coracoclavicular Ligament Reconstruction (Group B). Constant shoulder score was employed for the assessment of functional recovery before and after the surgery. Statistical analysis was performed in terms of age, gender, obesity (body mass index), Constant shoulder score, compliance of rehabilitation guidance, and the amount of reduction loss. The Constant score was significantly improved after surgery (P < 0.05). The score was better in Group B compared with Group A in the sixth month after surgery (P < 0.05), but showed no significant difference in the fifteenth month. Compliance with rehabilitation guidance significantly affected the values of the Constant score after the surgery (P < 0.05). Clavicular Hook Plate and EndoButton technique both are effective ways to treat Rockwood type III (or above) acromioclavicular dislocation. However, EndoButton technique is more effective for early functional recovery. Patients’ compliance with rehabilitation guidance is critical for the functional recovery after surgery.

Type V

We experienced acromial erosion and subsequent fracture after the treatment of Rockwood type V acromioclavicular dislocation with hook plate and coracoclavicular ligament augmentation. It was treated by using a surgical technique to address an acromial fracture and subsequent losses of reduction in acromioclavicular joint with two trans-acromial cortical screws (crossbar technique). The reduction state of acromioclavicular joint could be maintained by these two screws. Our crossbar technique could be considered as a good salvage procedure for the reduction loss caused by cutout or significant erosion of acromion after insertion of clavicular hook plate.

Abstract Background Acromioclavicular (AC) separation can be treated with the use of a hook plate. Some studies have reported that coracoclavicular (CC) ligament augmentation is necessary to reduce the complications of hook plate fixation, whereas others recommend hook plate fixation alone without augmentation. The aim of this study was to compare the results and complications between these two groups. Methods This was an observational case-control study. Patients with acute (less than 2 weeks) Rockwood type V AC separation were treated with a hook plate at our hospital. A total of 105 cases received hook plate fixation with CC ligament augmentation (group I), and 112 cases received hook plate fixation without augmentation (group II). Constant-Murley scores were used to evaluate the function before and after implant removal, and radiographs were taken to evaluate the complications. The results and complications were compared between groups. Results Before removal, the Constant-Murley score was significantly higher in group I (mean, 50.1) than in group II (mean, 42.6) (p = 0.004); however, there was no significant difference between groups at 3 and 6 months after removal. The incidence of significant acromion osteolysis was higher in group II (65/112) than in group I (25/105). Before removal, the patients with significant acromion osteolysis had worse Constant-Murley scores than those of the patients without osteolysis in both groups. The incidence of peri-implant fracture of the hook plate was higher in group II (8/112) than in group I (1/105). Conclusion The patients without CC ligament augmentation had worse functional results before hook plate removal, a higher incidence of radiographic acromion osteolysis, and a higher incidence of peri-implant fractures than those patients with CC ligament augmentation. Therefore, CC ligament augmentation is highly recommended to improve short-term outcomes and decrease complications for Rockwood type V AC separation treated by hook plate.
