Abstract
A fixing means () for fixation of bone fragments at bone fractures comprises a sleeve () and at least one pin () which is provided in said sleeve and a front end portion () of which can be driven out and retracted through a side opening () in the sleeve such that said end portion can be brought to engage bone material in one of the bone fragments and retracted out of the bone material. For facilitating said driving and retraction, the pin () comprises a fixing member () with said front end portion () and a driving and retraction member () which is rotatably connected to the fixing member. The driving and retraction member () is configured to, during rotation in a first direction relative to the fixing member (), displace the pin () in a forward direction relative to the sleeve () for driving the front end portion () of the pin out of the sleeve and into the bone material in said one bone fragment and, during rotation in a second, opposite direction relative to the fixing member, displace the pin in a backward direction relative to the sleeve for retracting the front end portion of the pin out of the bone material in said one bone fragment and into the sleeve.
