title: Stabilisation of a loosened femoral gamma nail by percutaneous cement injection (cementoplasty): a new technique.
abstract: Surgical repair of pertrochanteric and subtrochanteric fractures in the elderly is usually achieved using an endomedullary nail. Unfortunately, even today, some of the patients who undergo this intervention develop periprosthetic bone absorption over time that can lead to loosening of the prosthesis, resulting in pain, joint instability and the need for revision surgery. Surgical revision is hindered by potential complications related to patients' existing underlying medical conditions. It is often the case that these patients are weak and present comorbidities, which can lead to an absolute contraindication to surgery. An interesting alternative could be the stabilisation by percutaneous injection of cement (cementoplasty) in the periprosthetic space under CT and fluoroscopic guidance. In patients with absolute contraindication we performed percutaneous cementoplasty as treatment for femoral prosthesis loosening. Our procedure was technically a success following the end of the intervention period (follow-up: 6 months). The patient no longer experienced significant pain and showed stability of the prosthesis, as demonstrated by CT.
