Rehabilitation of a Patient Receiving a Large-Resection Hip Prosthesis Because of a Phosphaturic Mesenchymal Tumor.

Tumor-induced osteomalacia is an osteomalacic syndrome caused by a mesenchymal origin's tumor. The diagnostic procedure takes time and extensive investigations because of the characteristics of these tumors usually small dimensioned, slowly growing, non-invasive and therefore hard to locate. The differential diagnosis is determined by a bone biopsy. Tumor's surgical removal is the treatment of choice that leads up to a complete regression of the oncogenic malacic syndrome. In the clinical course of these patients we can often see multiple episodes of pathological fractures, peri-prosthesis fractures or prosthesis mobilizations, due to the malacic picture: surgical procedures are often widely demolitive and requires mega-prosthetic implant. The rehabilitative procedure used to take care of these patients, is described in the following case report and based on the collaboration between surgical and rehabilitative teams. Rehabilitative pathway after hip mega-prosthesis does not find references in medical literature: the outcomes analyzed in this case report demonstrate the efficacy of the rehabilitative procedure applied.
