Abstract

Background: Dislocation of the acromioclavicular joint is a common injury with a number of surgical interventions being described for its treatment. Among the different techniques developed, the LockDown synthetic implant (previously called the Nottingham Surgilig) is a synthetic ligament which has been increasingly used in the ACJ reconstruction with encouraging results.
Aim: To assess the post-operative results in patients who underwent acromioclavicular joint reconstruction using the LockDown system as well as measuring the radiographic appearance in the post-operative radiograph. Patients with a minimum 2year follow up were included in the study.
Materials and Methods: A retrospective case series evaluating 30 patients undergoing ACJ reconstruction with the LockDown system with at least two years of follow up. The clinical assessment was conducted before and after the operation using the Oxford shoulder score and the visual analogue pain score.Types of complications (infection rate, implant failure, bone osteolysis) as well as the radiographic appearance were also noted.
Results: The patients who underwent a Lockdown synthetic implant reconstruction for an acromioclavicular joint dislocation, improved from
24.67±2.35 to 46.8±2.35, p<0.001 in the 2year follow up appointment. According to the Visual Analogue Scale, the pain was reduced significantly from 6.87±0.33 to 1.11±0.22, p<0.001.Complications occurred in 6.6% of the patients, with 2 cases of superficial wound infections.
Conclusion: Patients who underwent a LockDown synthetic implant reconstruction had a significant improvement in their quality of life. From our case series, its widely use is totally justified, making the Lockdown system a valuable tool in the management of acromioclavicular joint dislocations.
