A study using the Lockdown™ device (formerly Surgilig™) to stabilise acromioclavicular joint disruption in conjunction with the modified Weaver-Dunn procedure in military personnel.  11 procedures were performed using Lockdown™.  The patients were followed up at 6 months postoperatively after being discharged from Consultant care.

The use of Lockdown™ proved to be beneficial in revision ACJ stabilisation surgery, failed conservative management and acute cases.  The functional outcome with Lockdown™ has allowed mobilisation and early return to full function making it a highly desirable option for use in active people.

Of the 11 patients that underwent acromioclavicular joint stabilisation using Lockdown™ there were no intra or post-operative complications.  Even on weight loading of the joint there was no disruption to the joint.

The study suggests very positive early results for the use of Lockdown™ in primary acromioclavicular joint disruption.  The benefit of a single definitive operation would be particularly useful in a military setting, although the reduction in in-patient time and duration of rehabilitation it has clear advantages for the wider NHS setting.
