“…5,8,10,13,14,17,26,33 Several reports suggest tumors of bone, including chondrosarcomas that arise in the proximal humerus, are more difficult to treat than other sites because of the proximity of vessels and nerves. 3,4,6,7,11,12,16,27,30,31,34,35 The muscular attachments to the humerus at the shoulder and the alterations in shoulder stability resulting from resection make this site a more complex problem in reconstruction. All reconstruction approaches, including fibular transplant, metallic implants, arthrodesis, and allograft reconstruction, may result in functional problems for the patient.…”

“…Segmental endoprosthetic replacement has gained popularity among orthopaedic oncologists as an expedient and effective means of addressing large segmental proximal femoral deficiencies after excision of primary metastatic tumors (1,4,14,17). In most large series, complication rates of these reconstructive methods have approached 15-20%, with radiographic evidence of loosening a common occurrence (1 JOJ 4,15,17).…”

Six techniques of proximal femoral replacement were compared in vitro with the use of compression, bending, and torsional testing in a canine model. One femur of each pair was osteotomized in the midshaft region, and the proximal portion was replaced with one of six techniques. These techniques included (a) a segmental proximal femoral endoprosthesis cemented into the distal femur with no allograft (technique ES); (b) a long-stem endoprosthesis press-fit into an allograft and cemented into the distal femur with a transverse osteotomy (technique AT); (c) the same construct as technique AT, but with a step-cut at the osteotomy (technique AS); (d) a long-stem endoprosthesis interlocked into an allograft and cemented into the distal femur with a transverse osteotomy (technique AI); (e) a short-stem endoprosthesis cemented into an allograft combined with one plate laterally stabilizing the allograft to the distal femur with a transverse osteotomy (technique AP1); and (f) the same construct as technique AP1, but with an additional plate cranially (technique AP2). A long-stem endoprosthesis cemented into the contralateral intact femur served as the control. Techniques that involved a long-stem endoprosthesis and cementing distally (AT, AS, and AI) were more resistant in torsion than the plated replacement techniques (AP1 and AP2). The segmental replacement construct (ES) was equal to or stronger than all other techniques under each testing condition. In torsion, the addition of a step-cut (AS) significantly lowered angular displacement of the reconstruction when compared with the reconstruction with a transverse osteotomy (AT) (p < 0.05). Bones with one-plate fixation (AP1) were significantly weaker in torsional stiffness and maximum torque and in mediolateral bending (p < 0.05) than all other techniques. The addition of a second plate (AP2) increased the mechanical properties of the construct so that it was greater than the one-plate method and was equal to (bending and compression) or still weaker (torsion) than the other techniques. The results indicate that segmental replacement methods and allograft/endoprosthetic composites that involve long-stem endoprostheses fixed with cement are mechanically superior to methods that involve short-stem endoprostheses with single or double plating at the osteotomy sites.

“…1 In the USA, Neer 2 developed a stemmed unconstrained humeral prosthesis specifically for the treatment of four-part fractures. His design was successful in providing a scaffold around which the proximal humerus could be rebuilt.…”
