Bone metastases of the upper limb are a frequent complication of primary tumors. The aim of this study is to evaluate treatment and functional results of patients with prosthetic reconstruction of the proximal humerus. Between 1975 and 2007, 67 patients were treated by resection of humeral metastasis and reconstruction with prosthesis. Cemented modular prostheses of the proximal humerus were implanted in 59 cases (all MRS Bioimpianti® prostheses), uncemented prostheses in 2 (HMRS® Stryker), 4 elbow Coonrad-Morrey prostheses (in 2 cases with bone allograft), 1 elbow custom-made cemented and 1 intercalary prosthesis (Osteobridge Merete®). Sites of primary tumors: kidney (23), lung (13), bone and unknow (7 each), liver and breast (3 each), bladder, endometrium, thyroid, soft tissues and nervous tissues (2 each), ovarium (1). Complications were evaluated and univariate analysis with actuarial Kaplan-Meier curves of implant survival was performed. Functional results were assessed with the MSTS system.Aim
Method
Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma. We review our experience to characterize its prevalence, treatment, relapse and survivorship at long term follow-up. Eighty-seven patients aged from 4 to 60 years (mean 20 years), were treated from 1985 to 2008. Lesions affected the femur (38), humerus (20), tibia (19), fibula (4), pelvis (3), foot (2) and radius (1). Eight patients had metastatic disease at diagnosis. Seventy-eight patients were treated with neoadjuvant chemotherapy with three or more drugs according to different protocols, nine had surgery as first treatment. Limb salvage surgery was performed in 71 cases, amputation in 14 and rotationplasty in one. One patient died before surgery. Prognostic factors were evaluated with Kaplan-Meier analysis.Introduction
Methods
There is doubt regarding resection compared to curettage for pelvic metastases. Previous studies have reported that curettage is associated with decreased survival compared with wide resection, and have justified a radical surgical approach to achieve pain palliation and tumor control. To evaluate the role of wide en bloc resection compared to curettage/marginal resection for patients with pelvic metastases. The rationale was that wide resection does not improve survival even in patients with solitary pelvic metastases.Background
