A distal transhumeral amputation typically occurs above the elbow. Cheesborough et al. suggest preserving the humerus bone segment at an approximate length of 6 to 8 cm. In addition to the length they recommend fixating the humerus at a 70 degree angle with a metal plate to give the arm rotational and leverage control when using a prosthetic arm (Cheesborough et al.,2015). In addition the shape and length of the residual humerus bone allows for increased suspension of a prosthetic arm (Tintle et al.,2010).
A proximal transhumeral amputation is more severe and challenging than a distal transhumeral amputation. A surgeon will attempt to salvage approximately 5 cm of the remaining humerus bone which allows for the prosthetic to be suspended
