BACKGROUND: The purpose of this study was to evaluate the clinical outcomes and complications of hook plate fixation in acromioclavicular (AC) joint dislocations and distal clavicle fractures.METHODS: We retrospectively reviewed a series of 60 consecutive patients with hook plate fixation for AC joint dislocation (group I) and distal clavicle fracture (group II). Groups I and II had 39 and 21 patients, respectively. Clinical results were evaluated using the pain visual analogue scale (VAS), simple shoulder test, and Constant-Murley scores. In addition, subacromial erosion and stiffness were evaluated as complications.RESULTS: At the removal, the pain VAS was 2.69 ± 1.30 and 4.10 ± 2.14 in groups I and II, respectively, which were significantly different (p=0.003). The simple shoulder test score was 9.59 ± 1.60 and 7.81 ± 2.67 in groups I and II, respectively, which were also significantly different (p=0.002). Subacromial erosion was significantly more frequent in group II (14/21 patients, 66.7%) than in group I (15/39 patients, 38.5%) (p=0.037), and stiffness was also higher in group II (17/21 patients, 81.0%) than in group I (22/39 patients, 56.4%), but it was not significant.CONCLUSIONS: Hook plate fixation showed good clinical and functional results for the treatment of acute unstable AC joint dislocation and distal clavicle fracture. But, in distal clavicle fractures, there are more subacromial erosion and stiffness compare with acute unstable AC joint dislocation.

Abstract Background Treatment options of acromioclavicular (AC) joint dislocation depend on the injury severity and the functional demand of the patient. Common surgical options include fixation across the AC joint, coracoclavicular (CC) fixation, and AC joint or CC reconstruction. However, the clinical superiority of these various procedures is controversial. This study aimed to compare the clinical and radiological outcomes of loop suspensory reconstruction and hook plate fixation for acute unstable AC joint dislocation.Methods We retrospectively included patients with acute unstable AC joint dislocation who were treated with loop suspensory reconstruction (group I, 23 cases) or hook plate fixation (group II, 14 cases) in our hospital from January 2010 to December 2016 with a minimum follow-up period of 1 year after surgery. We assessed the clinical outcomes of blood loss during surgery, surgical duration, duration of medication required for pain relief after the primary operation, occurrence of complications, and the Constant-Murley score; radiological analysis included postoperative arthritic change and the CC distance discrepancy ratio (CCDR) on preoperative and final follow-up plain films.Results The average follow-up duration was17.0±6.1 months. The mean duration of pain-control medication usage was 121.7±174.1 and 235.4±251.8 days in groups I and II, respectively, significantly lower in the CC reconstruction group (p=0.031). Group I revealed a superior Constant-Murley score at the final outpatient follow-up as compared with group II (71.7±15.8 vs 61.1±6.7, p=0.009). Regarding radiographic analysis, the hook plate group had a superior residual CCDR (group I vs II = 30% vs 80±40%, p<0.001). In addition, there were 9 cases of subluxation noted in group I and 2 cases in group II; however, 4 cases of acromion osteolysis were observed in group II.Conclusions The principle finding of the present study was that hook plate fixation was superior to loop suspensory reconstruction in terms of CC distance maintenance. However, the loop suspensory reconstruction group demonstrated superior clinical functional outcomes and less painkiller usage. A further randomized controlled trial with a long-term follow-up period is required.

Abstract In case of patients with spinal cord injury and concomitant acromioclavicular (AC) jointdislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion. Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver- Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weightbearing possible. In this case the Weaver- Dunn procedure with an additive hook-plate was performed in a 34-year-old male patient with a complete paraplegia and a posttraumatic chronic AC-joint dislocation. The patient was allowed to perform his wheelchair transfers with full weight bearing on the first postoperative day. The removal of the hook-plate was performed four months after implantation. At the time of follow-up the patient could use his operated shoulder with full range of motion without restrictions in his activities of daily living or his wheel-chair transfers.

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. Level of Evidence Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Introduction: Acromioclavicular (AC) joint dislocation is one of the most common shoulder injuries accounting for approximately 9-12% of all shoulder girdle injuries. Rockwood classification of AC joint dislocation is the most widely accepted classification system which classifies the injury into six types. Surgical management with open reduction and fixation with clavicular hook plate without the repair of coracoclavicular ligament has proved to be one of the best treatment options for Type III AC joint dislocations. Methods: Twenty-three patients with Rockwood Type III AC joint dislocation were included in the study. Open reduction was done and the fixation was done with the clavicular hook plate. The functional outcomes were assessed before and two months after the implant was removed using the Constant- Murley Score. Results: A total of 23 patients were included in the study with the mean age of 30.74 years. The plates were removed on an average of 6.43 months and mean follow up was 8.83 months. The functional outcome was assessed using the Constant- Murley Shoulder score. The pain scores were significantly better after the implant removal was done (p= 0.007). The final mean constant score was 74.6 ± 4.11 before removal and 93.91 ± 2.71 after implant removal and all the 23 patient had excellent result (>90 points). Conclusions: The pre-contoured clavicular hook plate has proved to be a good implant option in the fixation of Rockwood Type III AC joint dislocation without the need of any ligamentous repair

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.

Retrospective Comparative Study

Objective Clavicular hook plate application is one of the most commonly used treatment methods for acromioclavicular (AC) joint dislocation, although it may cause multiple postoperative complications. We modified the regularly used 0° hook plate to 15° and compared the clinical outcomes of these two hook plates for treatment of AC joint dislocation. Methods Forty-three patients with acute AC joint dislocation were randomly enrolled (0° hook plate, 20 patients; 15° hook plate, 23 patients). The American Shoulder and Elbow Surgeons (ASES) and visual analog scale for pain (VASP) scores were evaluated preoperatively and at 3 days and 1, 2, 3, and 6 months postoperatively and compared between the two groups. Results Compared with the preoperative scores, the 6-month postoperative ASES score gradually increased but the VASP score decreased in both groups. Furthermore, the ASES and VASP scores were significantly different between the two groups at every postoperative time point. Conclusion The 15° hook plate is superior to the 0° hook plate in reducing shoulder pain and improving postoperative recovery in the treatment of AC joint dislocation. Level of evidence Level III; Treatment study (retrospective comparative study).

Background: Combined injuries of Mid-shaft clavicle fracture and Acromioclavicular (AC) joint dislocation are rare, and only a few cases have been reported. Several treatment options including surgical, conservative and hybrid approach have been described. Yet, there is no consensus regarding the optimal management approach for this injury. Objectives: Here we reported a case of Mid-shaft clavicle fracture with associated type IV AC joint dislocation in a 29-year-old male following a cycling accident. Methods: Both parts of the injury were fixed surgically. Meanwhile, the patient did not follow the postoperative protocol and started the heavy sports activities one month after the surgery. Results: The patient showed up 6weeks after the surgery with slightly uncorrected AC joint. However, he was satisfied with the results and accordingly no intervention was done for the correction of the AC joint. Conclusion: Our case reveals the importance of adherence to the postoperative protocol in this combined and challenging injury and we recommend surgical fixation for such injury.

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.

Rockwood classification of AC joint dislocation is generally accepted worldwide. Treatment of Rockwood Type 1 and 2 AC joint is non-operative while all authors advocate operative treatment for Rockwood Type 4 and 5 AC joint dislocations. Thirty consecutive patients who underwent operation for acromioclavicular joint dislocation using clavicle hook plate from June 2015 were studied. The dislocations ranged from Rockwood type III to type V. Average follow up time was fourteen months ranging from four to twenty-four months. The outcome was measured using University of California Los Angeles (UCLA) shoulder score. All-the patient had good to excellent result.
