Brief summary

This study aims to inform clinical decision-making by thoroughly examining the outcomes of different treatment approaches for lateral quarter clavicle fractures and acromioclavicular dislocations. By evaluating the safety and efficacy of Knotless AC TightRope® repair devices and comparing short- and long-term results with other fixation techniques, the investigators hope to contribute to the improvement of treatment protocols for these common shoulder injuries. This research could significantly impact patients' quality of life by enabling optimal recovery and restoration of shoulder function.

Design outcomes

Primary

MeasureTime frameDescription
maintaining acromioclavicular reductionat 6 monthsThe effectiveness of the endo-button (Knotless Acromioclavicular TightRope®) in maintaining acromioclavicular reduction at 6 months will be assessed through radiological imaging.

Secondary

MeasureTime frameDescription
Assessment of the number of postoperative complicationsat 3 weeks, 3months, 6 months and 12 monthsDescription of all postoperative events
Evaluation of the procedure durationat day 1Evaluation of the procedure duration
Evaluation of the healing rateat 6 monthsEvaluation of the healing rate
Postoperative pain assessmentat 3 weeks, 3 months, 6 months ans 12 monthsPostoperative pain assessment aims to measure the intensity, location, and progression of pain experienced by the patient following surgery. It is essential for adjusting analgesic treatments, improving patient comfort, and preventing chronic pain. This evaluation relies on validated tools such as the Visual Analog Scale (VAS) The Visual Analog Scale (VAS) is a simple and widely used tool for measuring the intensity of pain experienced by a patient. It consists of a horizontal line, typically 10 cm long, with one end representing "no pain" (0) and the other end representing "worst imaginable pain" (10). The patient marks a point on the line that corresponds to their perceived pain level, and the distance from the "no pain" end to the mark is measured in centimeters to yield a score from 0 to 10.
Assessment of shoulder mobility recoveryat 3 weeks, 3 months, 6 months and 12 monthsAssessment of shoulder mobility recovery aims to evaluate functional improvement following surgery or injury. It relies on standardized tools such as the Constant Score, which combines pain, daily activities, range of motion, and muscle strength to provide a comprehensive and objective measure. Additionally, the Subjective Shoulder Value (SSV) offers a simple, patient-reported metric in which the individual rates the function of the affected shoulder as a percentage compared to a normal shoulder, giving a personal perspective on recovery.
Assessment of patients' quality of lifeat 3 weeks, 3 months , 6 months and 12 monthsAssessment of patients' quality of life is essential for understanding the broader impact of disease and treatment beyond clinical outcomes. The EQ-5D scale is a standardized instrument used to measure health-related quality of life. It evaluates five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated by the patient, and the results can be converted into a single index value reflecting overall health status. The EQ-5D also includes a visual analog scale (VAS) where patients rate their perceived health from 0 (worst imaginable) to 100 (best imaginable), providing both objective and subjective insights into their well-being.
