We present there new anatomical compartments for the surgical treatment of bone and soft part tumors about shoulder girdle. Without deltoid muscle we divide shoulder girdle into anterior, vascular and posterior compartments. The anterior compartment is composed of pectorious major, coracobrachial and biceps muscles. The vascular compartment is composed of neuro-vascular bundles and surrounding adi-pose tissue. The posterior compartment include other muscles and bones about the shoulder joint.We have treated 14 cases of bone and soft part sarcomas and easy recurred benign tumors, such as desmoid tumor and giant cell tumor of bone. We classified our 14 cases into three compartments. Cases of the posterior compartment had good prognsis due to the considerable amount of tissue. Five of five malignant tumors and three of four benign tumors had continuous disease free survival. Tumors at the anterior compartment were easy to invade the vascular compartment (1/2). Six of seven tumors related to vascular compartment failed after the surgery. Only one case had 4 years continuous disease free survival after the shoulder disarticulation.Four of eight cases of the posterior compartment often lost the function of the shoulder but all preserved the good function of the forearm. On the other hand, the function of the shoulder and forearm was easily damaged in cases of the vascular compartment (forearm 4/7, shoulder 6/7).According to the poor results of the surgery for cases of the vascular compartment, we should not hesitate to select the disarticulation.
