The use of a hook-plate in the management of acromioclavicular injuries. Report of ten cases.

A hook-plate is a clavicular small fragment AO plate with a hook engaging below the acromion. It is primarily used to secure the ligament repair in the treatment of displaced acromioclavicular joint dislocations. We have used the hook-plate in conjunction with a Weaver-Dunn procedure to secure the repair in seven patients. In another three we used this plate to reduce and stabilize distal clavicular fractures. Satisfactory results were obtained in all patients; the deformity disappeared, full pain-free shoulder movement was regained with no motor weakness, with a mean follow-up of 11 months (6-25 months). Our patients returned early to work and sports activities (mean period of three months). The three clavicular fractures healed. One patient developed a superficial would infection, which responded to antibiotics and would dressing. None of our patients required removal of the implant. The hook-plate appears to be a useful device for acromioclavicular trauma.
