The invention provides an implantable medical device for treatment of a proximal humerus fracture, comprising a base element to be anchored in the medullar cavity of the humeral shaft, a support element to be fixed with respect to the base element, wherein the support element is configured to support one or more bone fragments, wherein the medical device comprises positioning members configured to position the support element with respect to the base element in a range of rotational positions and axial positions, and wherein the medical device comprises a fixation device to fixate the support element, within the range of rotational positions and axial positions, in a desired rotational and axial position with respect to the base element. In an embodiment, the medical device is a non-occluding medical device, wherein after implantation the medullar cavity is not occluded by the medical device due to the open and non canal filling structure of the device preserving blood flow to the reattached bone fragments. |
