Supplementary Material for: Resection of Renal Cell and Prostate Carcinoma Sternum Metastases with Long-Term Follow-Up: A Report of 2 Cases

Introduction: Rarely solitary sternum metastases are addressed by resection. Two additional cases are presented as they are interesting because of their long-term follow-up. Case Presentation: Case 1: A renal cell carcinoma was treated by transabdominal nephrectomy at age 64. Right iliac bone and sternum metastases were diagnosed 7 months later and treated by internal hemipelvectomy followed by sternum metastasectomy 6 weeks after the internal hemipelvectomy. At 12-year follow-up, the patient appears disease free. Case 2: Prostate cancer was treated by prostatectomy at age 67. A subsequent solitary sternum metastasis was resected 10 years later for persistent PSA-activity despite repeated radiotherapy. The patient remains asymptomatic for 3 years now. Conclusion: Resection of sternum metastases may have curative potential and should be considered in tumours known to be rather resistant to chemo- and/or radiotherapy

Midterm results of mobile-bearing knee replacements

We examined the clinical and radiographic results of 93 patients affected by knee arthritis or osteonecrosis subjected to unilateral cementless mobile-bearing total knee arthroplasty with the LCS prothesis (Depuy/Johnson & Johnson). The mean follow-up was 9.5 years (range, 7–12 years). Clinical evaluation was performed using the Knee Society rating system, while radiographic evaluation was done according to the Knee Society roentgenographic system. At the latest follow-up, the mean knee score was 87 points: the functional score improved from 40 to 90. Radiolucent lines were small and not progressive. The implant survival at 12 years was 88%. Six knees (7%) required revision for implant-related problems. We conclude that the mobile-bearing prosthesis is a successful device even at long-term follow-up
