Background. Acromioclavicular (AC) joint dislocation is a common shoulder problem. However, information about the basic epidemiological features of this condition is scarce. The aim of this study is to analyze the epidemiology of isolated AC dislocation in an urban population.Materials and Methods. A retrospective database search was performed to identify all patients with an AC dislocation over a 5-year period. Gender, age, affected side and traumatic mechanism were taken into account. X-rays were reviewed by two of the authors and dislocations were classified according to the Rockwood’s criteria.Results. A total of 108 patients, with a mean age of 37.5 years were diagnosed with AC dislocation. 105 (97.2%) had an isolated AC dislocation, and 3 (2.8%) were associated with a clavicle fracture. The estimated incidence was 1.8 per 10000 inhabitants per year and the male-female ratio was 8.5 : 1. 50.5% of all dislocations occurred in individuals between the ages of 20 and 39 years. The most common traumatic mechanism was sport injury and the most common type of dislocation was Rockwood type III.Conclusions. Age between 20 and 39 years and male sex represent significant demographic risk factors for AC dislocation.

Abstract Background: Ipsilateral midshaft clavicle fracture and AC joint dislocation are rare, with very few cases reported. Once the AC joint dislocation were missed diagnosis, the shoulder function may be affected and medical dispute was easy to occur. The aim of this study was to gather data relating to ipsilateral midshaft clavicle fracture and AC joint dislocation to develop evidence-based diagnosis guidelines as none are currently available.Methods: A study was conducted of the PubMed and Google Scholar databases to identify cases of ipsilateral midshaft clavicle fracture and AC joint dislocation. Data collected about each case included age and gender of the patient, mechanism of injury, fracture and dislocation classification. The authors report 2 additional ipsilateral midshaft clavicle fracture and AC joint dislocation cases.Results: 21 cases were identified for inclusion in this research, 19 from the literature and 2 reported by the authors. All the patients were injured by high energy trauma. For the midshaft fracture, 16/21 (76.2%) patients belonged to Type A classification, and 5/21 (23.8%) patients belonged to Type B classification. For AC joint dislocation, 11/21 (47.6%) patients belonged to Type IV classification, 4/21 (19.0%) patients belonged to Type VI classification, 5/21 (23.8%) patients belonged to Type III classification and 1/21 (4.7%) patients belonged to Type V classification.Conclusions: There are limited data available about the diagnosis of ipsilateral midshaft clavicle fracture and AC joint dislocation. From the cases reviewed, we find that simple midshaft clavicle caused by high energy injuries may be associated with ipsilateral AC joint dislocation. Physical examination, careful observation of preoperative X-ray and fluoroscopy including the AC joint during operation were key to diagnose the injury.

Clinical And Radiological Results

Background: We aimed to assess the effect of plate hook bending in treatment of acromioclavicular (AC) dislocation by analyzing clinical and radiological results according to the angle of the plate hook (APH).Methods: This was a retrospective, observational, case-control study including 76 patients with acute AC joint dislocation that were divided into two groups according to treatment with bent or unbent plate hook. The visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion (ROM) were evaluated as clinical outcomes. Comparative coracoclavicular distance (CCD) was measured to evaluate radiological outcomes.Results: While the VAS and ASES of the bending group at 4 months after surgery were significantly higher (P=0.021, P=0.019), the rest of those and ROM showed no significant difference. The initial CCD decreased from 183.2%±25.4% to 114.3%±18.9% at the final follow-up in the bending group and decreased from 188.2%±34.4% to 119.1%±16.7% in the non-bending group, with no statistical difference (P=0.613). The changes between the initial and post-metal removal CCD were 60.2%±11.2% and 57.3%±10.4%, respectively, with no statistical difference (P=0.241). The non-bending group showed greater subacromial osteolysis (odds ratio, 3.87). Pearson’s coefficients for the correlation between APH and VAS at 4 months after surgery and for that between APH and ASES at 4 months after surgery were 0.74 and –0.63 (P=0.027 and P=0.032), respectively.Conclusions: The APH was associated with improved postoperative pain and clinical outcomes before implant removal and with reduced complications; therefore, plate hook bending is more useful clinically during plate implantation.

Abstract Purpose Double-endobutton technique, as a widely accepted strategy for the treatment of acromioclavicular joint dislocation, is undergoing constant improvement. This study aims to assess the clinical effect of a modified single-endobutton combined with the nice knot in the fixation of Rockwood type III or V acromioclavicular joint dislocation. Methods From January 2016 to June 2019, 16 adult patients (13 males and 3 females) with Rockwood type III or V acromioclavicular joint dislocation were treated with a modified single-endobutton technique combined with the nice knot in our department. The age ranged from 18 to 64 years old with an average of 32.8 years old. Operative time, intraoperative blood loss, post-operative clinical outcomes and radiographic results were recorded and analyzed. Preoperative and last follow-up scores in the Constant-Murley Scale, Neer score, Rating Scale of the American Shoulder and Elbow Surgeons and VAS scale and complications such as infection, re-dislocation, implant loosening, medical origin fracture and hardware pain were recorded and evaluated. Results Sixteen patients were followed up for 6 to 18 months with an average of 10.3 months. The operative time was 50–90 min with an average of (62.5 ± 3.10) min. The intraoperative blood loss was 30–100 ml, with an average of (55.0 ± 4.28) ml. The complications, such as wound infection, internal fixation failure and fractures, were not found in these cases. According to Karlsson criteria, there were excellent in 14 cases, good in 2 cases at the final follow-up. The mean VAS score of the patients was 5.88 ± 0.26 preoperatively, compared with 0.19 ± 0.14 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). The mean Constant score was 45.5 ± 2.0 preoperatively, compared to 94.0 ± 0.73 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). Patients had statistically significant preoperative and postoperative AC (acromioclavicular distance) and CC (coracoclavicular distance) distances (P < 0.05); 6 months postoperatively the AC(P = 0.412) and CC(P = 0.324) distances were not statistically significant compared to the healthy side. Conclusion Nice knot provides a reliable fixation for the single-endobutton technique in the treatment of acromioclavicular dislocations. The modified single-endobutton technique combined with the nice knot can achieve good clinical outcomes in the treatment of Rockwood type III or V acromioclavicular joint dislocation.

Abstract Background Numerous surgical methods have been used for acromioclavicular joint reconstruction.In this study, we analyzed the clinical and radiographic outcomes of truly anatomic coracoclavicular ligaments reconstruction (TACCR) and truly anatomic acromioclavicular ligaments reconstruction (TAACR) using suture anchor and Endobutton fixation for treatment of acromioclavicular joint dislocation. Methods 48 patients (mean age 49 years) with severe acromioclavicular joint dislocation. The patients were classified as Rockwood type III (n=28), IV (n=3) and V (n=17). All patients were operatively treated using anchor moored positioning technique by suture anchor and Endobutton fixation. Clinical and radiographic evaluation include the visual analog scale (VAS), Constant scores (CS) and American Shoulder and Elbow Surgeons (ASES) scores and radiographic outcomes. Results The mean follow-up was 34 months. The VAS decreased from 5 preoperatively to 0 at 24 months (P < .001). The CS and ASES scores improved from 43, 44 preoperatively to 96, 97 at 24 months separately (P < .001). Meanwhile, 47 patients (97.9%) demonstrated stable anatomical fixation on final postoperative radiographs. Loss of reduction occurred in 1 patient (2.1%), but was not correlated with functional outcome. Conclusions Anchor moored positioning technique with Bi-directional fixations by suture anchor and Endobutton fixation represents a new and reliable treatment of AC joint dislocation.

Abstract Background Os acromiale can be potentially missed or misdiagnosed as acromion fracture, and this can affect treatment determination if it is complicated with an ipsilateral shoulder injury. The clavicle hook plate is a widely used technique for distal clavicle injuries, leading to transacromial erosion, particularly when in the presence of os acromiale. Case presentation A 70-year-old man and a 78-year-old man who had limited mobility and severe pain in their right shoulders following falls attended the emergency center. Both patients were diagnosed with os acromiale with CT or MRI and acute distal clavicle fracture or acromioclavicular joint dislocation. Following a comprehensive evaluation, os acromiale may limit the application of a clavicle hook plate due to potential transacromial erosion. The distal clavicle fracture with ipsilateral os acromiale received treatment with a volar radius locking T plate, and the acromioclavicular joint dislocation with ipsilateral os acromiale was reconstructed using suture anchors. Both yielded satisfactory outcomes and voided transacromial erosion. Conclusions Ipsilateral os acromiale may be a relative contraindication to the clavicle hook plate. An axillary lateral radiograph is recommended to detect potential os acromiale in patients using a hook plate.
