Virtual planning techniques allow a differentiated evaluation of the extent of the bone loss and the planning of different augmentation options.

Shoulder complaints and incidence of shoulder pathologies after contralateral major amputation in the mid and long-term.

Introduction: Amputations of the upper extremity are rare but present a life-altering event that is accompanied with considerable restrictions for the affected patients. Even with functional prosthesis, tasks of the amputated limb are usually transferred to the unaffected arm which could result in complaints of the unaffected shoulder in the mid and long term. We therefore aimed to investigate musculoskeletal pain and morphological degenerative changes of the shoulder following a contralateral amputation.
