title: The surgical manegement of metastases to humerus-clinical evaluation.
abstract: Background. The humerus is a common localisation of cancer metastases. The restoration of anatomical order and tumor resection within humerus is important for patients quality of everyday life and for their pain relief. The surgical treatment is one of the most important part of the whole oncological ways of tratment.<br /> The study objective was a clinical assesment of tumor resection and reconstruction within humerus according to matastasis localisation and the choice of surgical technique.<br /> Material and methods. In the years 1999-2002 19 patients underwent surgery due to pathological fracture or/and cancer metastasis within humerus. The shaft localisation of the tumor was found in 8 cases and in 11 patients the metastatic foci were found in proximnal diaphysis. In patients with proximal diaphysis localisation of the tumor the partial resection with subsequent joint exchange procedure was made. The humeral shaft metastatic cancer changes were treated by the segmental resection with subsequent surgical cement filling or auto/allogenical bone grafting combined with intramedullary nail or AO/ASIF plate stabilisation. The average follow-up period was 8,5 months.<br /> Results. In patients after resection with shoulder joint alloplasty according to the Enneking test a very good result was found in 7 and very good in 4 cases.<br /> In patients with femoral shaft metastatic tumor locaslisation, 6 good and 2 fair results were found. In 1 patient after 2 months rehabilitation a reoperation was needed due to the mechanical destabilisation. The best results were found in patients after intramedullary nailing.An acute soft tissue inflamation requiering surgical treatment was found in 1 patient after shoulder joint replacement.<br /> Conclusions. After clinical analysis of the material we highly recomend the partial humeral bone resection with subsequent shoulder alloplasty in patients with proximal humeral diaphysis metastatic localisation. In cases with shaft localisation a better results were found after intramedullary nailing compared to common plate technique.
