------------------------------------Introduction: metastases of the humerus are very commune lesions. They are usually treated conservatively:
immobilization and radiotherapy are often sufficient because of the humerus das not have to support weight baring.
Nevertheless, when the osteolysis is important surgery could be advisable to decrease the risk of fracture.
Intramedullary nailing is considered the mainstay treatment for radiosensitive metastasis but unfortunately the presence
of an electron dense material interferes with successive radiotherapy and with its effectiveness.
The IlluminOss system consists in an intramedullary stabilization with a nailing system made filled of a fluid monomer
that exposed to UV polymerizes becoming harder, so that it can be drilled and locked with screws. We present the
preliminary experience in treating fractures and impending fractures with this system.
Patients and methods: from October 2014 to January 2015, four patients, three males and one female, underwent
intramedullary stabilization with IlluminOss system for metastatic osteolysis of the humerus.
The average age was 69,9 years (62-77); three out of four were affected by multiple myeloma, the last one by
metastases of breast cancer (male, 77 y.o.). Lesions were located at the proximal metaphysis in two cases, at the
central diaphysis in one case and at the distal diaphyseal third in one case.
Results: all surgeries were performed without problems and complications; a screw was used to lock the nail in metadiaphyseal lesions. Three out four patient completed adjuvant radiotherapy with a good consolidation/ossification; in the
last performed case radiotherapy is ongoing.
Discussion: intramedullary stabilization is the mainstay treatment in metastatic patient for impending or already occurred
fractures. Several nails are commercially available but the most of them gives artifacts at CT scan interfering with
adjuvant chemotherapy. The presenting system is characterized by a low artifacts level allowing a safer postoperative
treatment. Moreover it is inserted in a fluid status so that the access is minimally invasive and less obliged than that of
traditional nails; it better adapts to the intramedullary shape of the bone even it those case were a deformity is present.
Conclusion: the IlluminOss intramedullary stabilization system could be considered a good method for treating osteolisis
of the humerus. More studies with more numerous series are necessary to verify the effective advantages for the
patients and possible problems in case of removal.
