Summary
Brief summary (as posted)
This is an interventional randomized controlled trial that will compare patients who underwent segmental hip replacement using mega-implants with either porous collar or porous collar with HA. Patient recruitment will continue for 18 months. Parameters to be investigated are radiographic measures of bone incorporation into the implants, as well as patient functional outcomes. Clinical follow-up will last for 24 months for each patient.

- description
- Patients with neoplasm of femur bone who require segmental bone resection and replasement with a large prosthesis would receive an implant which collar (a circular part that comes into direct contact with the remaining bone) will be porous, to allow for bone ingrowth and stabilization of the implant.
