Abstract: The purpose of this study is to define the minimum requirements for total scapular replacement with metallic
endoprosthesis and compare it to suspension arthroplasty. A retrospective analysis was performed of three
musculoskeletal tumor registries for patients with scapulectomy for musculoskeletal tumors. Patients were
divided into two groups: Group I included eleven patients who had endoprosthetic scapula replacement
(Endotec, Bloomfield, NJ, Howmedica, Rutherford, NJ). Group II included nine patients with suspension
arthroplasty. Overall MSTS scores were higher in group I than in Group II (23.5+2.5 versus 17+2.6;
p=0.0001). Scores in Group I was significantly higher in all categories but dexterity. The lowest score in
both groups was in the function category (3.6+0.8 versus 1.7+1.0; p<0.001). The data shows that patients
with endoprosthetic replacements have higher MSTS scores in emotional acceptance and function,
compared to those with suspension arthroplasty. The greater motion found in group I (endo) was most
evident in forward flexion, abduction and external rotation. This was thought to be a results of lateral
positioning, scapulothoracic reconstruction and pseudoarthrosis.Keywords: Scapula, Endoprosthetic, Musculoskeletal Oncology, Suspension Arthroplasty
