Abstract
The proximal humerus is the third most common site for bone tumors, both primary and metastatic cancer. Regaining shoulder function is challenging due to the removal of muscles and bone to obtain safe surgical margins.
When the axillary nerve and deltoid muscle can be spared, modular reverse total shoulder arthroplasty (mRTSA) can be used. Advantages of this type of reconstructions include:
-
1.
prosthetic reconstruction that affords immediate stability permitting early mobilization;
-
2.
modularity with different components ready for use and adaptable to the length required;
-
3.
inverse geometry that counterbalances the absence of rotator cuff, permitting satisfactory functional results.
