An inexpensive reconstruction method after resection in tumors of the proximal humerus with extensive involvement of the diaphysis

摘要

Limb salvage is now the norm for a large majority of malignant bone tumors. The proximal humerus is the third most common site for the occurrence of malignant tumors of bone. In tumors of the proximal humerus with large volume disease, extensive involvement of the diaphysis is not infrequent. Resection may often extend as far as the distal metaphysis in order to obtain adequate oncologic margins. A very small distal stump of bone poses unique challenges in reconstruction where conventional reconstruction modalities may be difficult to apply. We describe the use of a customised plate to reconstruct these defects which offers an inexpensive, easy to use, durable reconstruction option. It provides adequate shoulder and arm stability and ensures excellent hand and elbow motion with good functional results.Keywords: Diaphysis, humerus tumor, inexpensive reconstruction
