A surgical technique for radical excision of soft tissue malignant sarcomas is described and functional and oncologic outcomes of this procedure in three patients diagnosed of soft tissue sarcoma are reported. A “Y” approach is used to perform a complete release of deltoid attachments in the scapula, clavicle and proximal humerus. This approach also allows an excision of the biopsy site, avoiding the establishment of large flaps coverage. No local recurrence or surgical wound complications were found. All the patients showed a good range of motion (130º of abduction) but loss of strength in abduction and antepulsion was found. We conclude that patients with malignant soft tissue tumors involving the deltoid muscle which undergo a wide resection of the bump through the previously described technique have an excellent functional outcome with low risk of recurrence, in absence of concomitant rotator cuff injuries.
