Concept for Minimally Invasive Hook Plate Stabilisation of the Acromioclavicular Joint.

AIMS: Despite the availability of various operative procedures, hook plates are still one of the main implants used for the treatment of acromioclavicular (AC) joint dislocation. The aim of this report is to present a novel minimally invasive operation technique for AC hook plate fixation. The functional outcomes of patients operated upon with this technique are presented.

PATIENTS AND

METHODS

A retrospective analysis was performed for 5 patients who were operated upon with minimally invasive hook plate fixation. The QuickDASH score (QDS) and subjective shoulder value (SSV) were used to express functional outcomes, and the numeric rating scale (NRS) was used to evaluate pain.

RESULTS

The mean (SD) follow-up was 30±7 months. Patients were hospitalized for a mean of 3±1 days and operated upon for a mean of 54±7 minutes. Functional outcomes measured with the QDS showed a median (IQR) of 2.3 (0 - 6.8) and a median SSV relative to the healthy side of 95% (89 - 100). The median NRS was 0 (0 - 0).

CONCLUSION

Minimally invasive hook plate fixation for acromioclavicular joint dislocation led to excellent functional outcome scores without complications in a small case series of 5 patients.
