About this study
Official title: Conservative or Surgical Management of Rockwood Type III to V Acromioclavicular Dislocations: A Non-inferiority Randomized Study
This study will evaluate the non-inferiority of conservative management for acromioclavicular clavicle disjunction, compared with surgical management. Half of patients will be treated with a specific standardized rehabilitation protocol, and the other half will be treated with coracoclavicular and acromioclavicular fixation, followed by a another specific standardized rehabilitation protocol.
Outcomes:
Read more
The primary outcome is the non-inferiority of the conservative management over surgical management of Rockwood III-V Acute acromioclavicular joint dislocation (ACJD) without PICCAT with American Shoulder and Elbow Surgeons (ASES score) at one year. If the non-inferiority is reached, the non-inferiority of the conservative management over surgical the management of Rockwood III-V ACJD with PICCAT using ASES score at one year will be evaluated.
Secondary outcomes were radiological criteria (i.e. comparison of ipsilateral and contralateral coracoclavicular distance on anterior view; and dynamic posterior shaft of the cross-body adduction Basamania/Alexander view) return to sports, work absenteeism, complication rate, cosmetic results, patients satisfaction, Constant score, Single Assesment Numeric Evaluation (SANE) score, Acromioclavicular Joint Instability (ACJI) score, ASES score at others timepoints, and range of motion of the implicated shoulder. Finally, multivariable regression analysis will be performed in order to evaluate the impact of predictors of interest on ASES score at one year.
Read the detailed description
Background and rationale:
ACJD can be either managed conservatively or surgically. Concerning functional outcomes, it usually accepted that ACJD Rockwood state I and II should be treated conservatively.It is still debated whether grade III should be treated surgically or not, and only experts opinion suggest that grade IV and V has better surgical outcome than conservative. The main literature failed to demonstrate the superiority of the surgical management for functional outcomes. Despite this, operative management results in a better cosmetic outcome, but conservative management is associated with a lower duration of sick leave and lesser costs. It has been purposed by a worldwide expert consensus (ISAKOS consensus) that dynamic posterior clavicle impaction into the trapezius muscle (PICCAT) could be a predictive factor of poor functional outcome in case of conservative management.
Hypothesis:
H0: ASES score at one year of follow-up is better with surgical management than with conservative management.
H1: one year ASES score after conservative management is not inferior as after surgical management. H1 will be first tested without PICCAT. If H1 is validated, it will then be tested again including all patients, PICCAT or not.
Study design:
This multicentric case-control study is randomized 1:1 between conservative and surgical treatment of ACJD. It is a non-inferiority trial that includes 176 patients that suffers from acute ACJD Rockwood grade III-V. Conservative management will consist of a sling for 10 days followed by a standardized physical therapy program, (Cote et al. 2010) and surgical management will consist of coracoclavicular and acromioclavicular fixation and specific rehabilitation. Clinical follow-up will last one year.
Statistical analysis
Non-inferiority statistical analysis will be performed upon appropriate unilateral 95% confidence interval margin (Z = -1.645), with a non-inferiority margin of 6.4, corresponding to ASES minimal clinically important difference. Analysis is planned in case of "intention to treat" method, but, if patients of the conservative management group undergo surgery because they are unsatisfied, ASES score will be measured prior surgery instead of at one year of follow-up. No statistical adjustments on potential confounders are planned.
Sample size calculation:
ASES score minimal clinically important difference has been estimated to 6.4. ASES standard deviation after surgical management of ACJD has been estimated to 9.7. If there is truly no difference between the surgical and conservative treatments, then 80 patients are required to be 90% sure that the lower limit of a one-sided 95% confidence interval (or equivalently a 90% two-sided confidence interval) will be above the non-inferiority limit of -6.4. Mazzoca, one of the main authors of ISAKOS consensus (ISAKOS), has reported operating 50% of Rockwood type III-V ACJD. From this, we can strongly suppose that 50% of Rockwood type III-V ACJD presents PICCAT. Considering a 10% of drop-outs, we therefore need 80/(50%)*110% = 176 patients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will evaluate the non-inferiority of conservative management for acromioclavicular clavicle disjunction, compared with surgical management. Half of patients will be treated with a specific standardized rehabilitation protocol, and the other half will be treated with coracoclavicular and acromioclavicular fixation, followed by a another specific standardized rehabilitation protocol.
Outcomes:
The primary outcome is the non-inferiority of the conservative management over surgical management of Rockwood III-V Acute acromioclavicular joint dislocation (ACJD) without PICCAT with American Shoulder and Elbow Surgeons (ASES score) at one year. If the non-inferiority is reached, the non-inferiority of the conservative management over surgical the management of Rockwood III-V ACJD with PICCAT using ASES score at one year will be evaluated.
Secondary outcomes were radiological criteria (i.e. comparison of ipsilateral and contralateral coracoclavicular distance on anterior view; and dynamic posterior shaft of the cross-body adduction Basamania/Alexander view) return to sports, work absenteeism, complication rate, cosmetic results, patients satisfaction, Constant score, Single Assesment Numeric Evaluation (SANE) score, Acromioclavicular Joint Instability (ACJI) score, ASES score at others timepoints, and range of motion of the implicated shoulder. Finally, multivariable regression analysis will be performed in order to evaluate the impact of predictors of interest on ASES score at one year.

H0: ASES score at one year of follow-up is better with surgical management than with conservative management.
H1: one year ASES score after conservative management is not inferior as after surgical management. H1 will be first tested without PICCAT. If H1 is validated, it will then be tested again including all patients, PICCAT or not.

Conservative management will consist of a sling for 10 days followed by a standardized physical therapy program, (Cote et al. 2010) and surgical management will consist of coracoclavicular and acromioclavicular fixation and specific rehabilitation. Clinical follow-up will last one year.

Questions about this trial
What is this clinical trial studying?
A study testing Conservative management and Surgery in people with Acromioclavicular Joint Dislocation and Conservative Versus Surgical Management, run by La Tour Hospital at 1 site in Switzerland.

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

What does the primary outcome measure?
The non-inferiority of the conservative management over surgical management of Rockwood III-V ACJD without PICCAT, regarding ASES score. (time frame: one year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02677441, which also lists 5 linked publications.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
