Distal clavicle fractures have a significant non-union rate, and are often managed operatively. Many of the fixation devices used have a high complication rate or require removal. An arthroscopic technique using the Tightrope device (Arthrex) has been used in our institution. We aimed to describe our initial results.

Eighteen cases were identified retrospectively, and the notes and radiographs reviewed. Twelve patients were male, six female, with mean age 33 years. All fractures were displaced, lateral to the coraco-clavicular ligament complex: six showed marked comminution. Mean follow-up was thirteen weeks. Fifteen fractures united, with a mean radiological time to union of 8 weeks (range 6-13 weeks). There were three surgical complications. In one, the clavicular button was not seated correctly on bone, and early failure required revision surgery. In another, there was inadequate reduction, radiographic non-union at five months and subsequent device failure. In the last, there was radiographic non-union, but the patient was asymptomatic.

The arthroscopic tightrope device provides minimally invasive stabilisation and reliable union. The complications seen were related to incorrect technique, and anticipate the complication rate to diminish as the technique is developed. We recommend the use of this technique for the stabilisation of distal clavicle fractures.
