Brief Summary

Bone metastases appear in many cancers. They are associated with severe pain that is refractory to standard treatment. Improving the quality of life and better pain relief is therefore an essential goal of the treatment of metastatic disease. The most common site of long bone metastases is the superior femoral epiphysis. The usual management of patients with bone metastases in the superior femoral epiphysis is based on gamma implant osteosynthesis when there is a known risk of fracture (Mirels score\> 8). Nonetheless this surgery is only accessible to a few patients because of the associated morbidities. Percutaneous cementoplasty has been developed to treat patients who are not eligible for conventional surgery. It consists in a filling of the bone cavity created by metastasis using an acrylic resin. However, these approaches do not completely prevent the risk of upper femoral epiphyseal fracture due to the low mechanical resistance of the resin to shear movements. The Y-STRUT® implantable medical device was developed to overcome this risk of superior femoral epiphyseal fracture by the biomechanical strengthening of the proximal femur in addition to cementoplasty. It has been successfully tested in more than 70 patients with cancer but access to reimbursement and the APHP market have been postponed due to lack of sufficient clinical evidence. The investigators propose this prospective phase 2a study in order to provide evidence of the performance of the Y-STRUT® implant.

Outcome Measures

Primary Outcomes (1)

  • Measure of Quality of Life for each patient within one month after the implantation

    Measure of the Quality of Life score using the questionary of quality of life of the European Organization for Research and Treatment of Cancer BM-22. Patients answer at 22 questions to describe their quality of life during the past week. For each question, patient must choose between 1.not at all, 2.a little, 3.enough, 4.a lot. A global score is calculated by adding the 22 score of each questions. The higher value of this global score represents the better outcome.

    30 days

Secondary Outcomes (18)

  • Target lesion fracture within one month after the implantation

    30 days

  • Target lesion fracture within 2 months after the implantation

    2 months

  • Non-target femoral fracture within 2 months after the implantation

    2 months

  • Non-target femoral fracture within one month after the implantation

    30 days

  • Analgesic medication needs (type and dose) within one month after the implantation
