Background:
Avulsion fractures of the scaphoid tubercle (Herbert type A1) are rare. Recommendations in the literature focus on a four to six week plaster immobilization including the thumb. Surgery is recommended in case of additional injuries to the carpus.
Material And Methods:
In a retrospective investigation including a 36 month period we reviewed acute fractures of the scaphoid and avulsion fractures of the scaphoid tubercle.
Results:
We found 81 acute scaphoid fractures, four of them (4.9 %) were isolated tuberculum avulsions. Three cases were extra-, one case an intraarticular fracture. The first were treated conservatively, the last with a percutaneous screw.
Conclusions:
Following our own experiences with those rare injuries we recommend a differentiation of the fracture type into extraarticular injuries where conservative treatment should still be performed and intraarticular fractures where percutaneous screw osteosynthesis should be discussed.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
