Malawer = Malawer classification of the of shoulder girdle resections [18]; MSTS = Musculoskeletal Tumor Society; P = partial resection; R = reinsertion; P¹ = intact posterior bundle; P² = resection of ¾; P³ = resection of ¼; R^B = reinsertion long biceps on short biceps muscle; R^T = reinsertion triceps on deltoid muscle; R^P = reinsertion pectoral muscle on clavicle; R^L = reinsertion latissimus dorsi on acromion; I = intraarticular proximal humeral resection; V = extraarticular humeral and glenoid resection; A = absence of resection of abductors; B = resection of abductors; MSTS = Musculoskeletal Tumor Society classification of skeletal resections about the shoulder girdle [13]: S2 = glenoid resection; 3 = head of the humerus; 4 = proximal metaphysis of the humerus; 5 = shaft of the humerus; E1 = distal metaphysis of the humerus.
