approach The approach to the tumor for each Selleckchem Birinapant patient was determined by precise preoperative imaging studies. The primary lesion of the scapula for all seven patients were mainly detected in region S2, the acromion/glenoid complex (Figure 1, Figure 2) with partial lesions occurring in region S1, the blade/spine of the scapula as categorized using the MSTS classification [1]. The incision was centered in the middle of the tumor. Thus, a posterior extensile incision was made in four patients (#1, 2, 5, and 6) TPX-0005 mw starting at the inferior angle along the medial border of the scapula, curving laterally through the spine to the tip of the acromion. The overall length of the incision was

determined based on the extent of each patient’s lesion. In another patient (#7), a vertical incision was created that extended along the lateral border from the inferior angle of the scapula to the intermedial portion of the clavicle, following the previous incision made during a prior partial scapulectomy. In another patient, (#3) the incision had the same starting point as the patient #7, but then extended medially from the lateral superior angle to the medial INK1197 clinical trial superior angle of the scapula along the spine. In the last patient, (#4) the incision was extended from the sternoclavicular joint along the clavicle and continued over the shoulder along the deltopectoral groove. Figure 1 Radiographs of the patient with primary chondrosarcoma (#1). (A) The plain radiograph shows a lytic bony lesion in S2. The other lesion in the proximal humerus was identified as chondroma. Figure 2 Computed tomography scan shows the scapular lesion expanding into the

surrounding muscles. Resection and surgical margins The affected supraspinatus, infraspinatus, and subscapularis were identified in six patients (#1, 2, 4, selleck inhibitor 5, 6, and 7). The involved teres minor and teres major in four patients (#3, 4, 6, and 7) and the affected trapezius in three patients (#2, 3, and 7) were identified. The involved partial deltoid (anterior or posterior), latissimus dorsi, and biceps brachii were identified in two patients, respectively (#4 and 7, #3 and 7, and #1 and 4). The affected serratus anterior, coracobrachialis, rhomboideus, and the suprascapularis were identified in one patient each (#1, 4, 2, and 1, respectively). The articular capsule was essentially intact in all patients. After exposing each patient’s tumor, the supporting musculature was examined.
