Abstract
Acromioclavicular joint injuries are one of the most common injuries in the shoulder girdle complex. Surgical management is considered based on patient profile, level of activity, pain, and classification of injury. To date, a vast array of surgical techniques have been proposed and described in the literature, a possible reason being that the optimal solution is still uncertain. The aim of this study is to determine the efficacy of an alternative surgical technique.
This study is a retrospective case series of 80 patients that have been operated by a single surgeon over a period of 6 years. A novel surgical technique, the ‘BiPOD method’, was applied where a synthetic artificial ligament (LARS®) is used to reconstruct and reduce the acromioclavicular joint.
The technique is done in a reproducible manner, where a single continuous artificial ligament is used to reduce and reconstruct both, the coracoclavicular and acromioclavicular ligament complexes to achieve bidirectional stability. Patients were followed-up postoperatively, either clinically where possible or telephonically. The Acromioclavicular Joint Instability Score (ACJI) and radiographic measurements were used to determine the clinical and surgical outcome of the surgery.
Radiographic parameters, measuring the reduction of the coracoclavicular- and acromioclavicular joint, were analysed and documented. The results showed marked improvement in both, the coracoclavicular distance and acromioclavicular distance. Clinically, using the ACJI scoring system, the patients reported substantial improvement in pain and function. Complications were recorded but were insignificant.
The BiPOD surgical technique, making use of an artificial LARS® ligament, has proven acceptable outcomes in the surgical management of acromioclavicular joint dislocations.
