Incidence of Cut-out Using Intramedullary Nails With Double Cephalic Screw vs. Unique in Pertrochanteric Fractures
The goal of this clinical trial is to compare outcomes in the treatment of proximal femur fractures. The main question it aims to answer is whether the use of a double cephalic screw prevents nail failure (cut-out).

Participants will be treated using open reduction and internal fixation with a proximal femoral nail. Researchers will compare intramedullary nailing with a single cephalic screw (Gamma nail) and with a double cephalic screw (Chimaera nail) to see the cut-out rate.
- EligibilityCriteria: Inclusion Criteria:  Patients with proximal femur fracture (OTA/AO 31-A1, A2 and A3) requiring surgical treatment. Signing of written informed consent according to current legislation before collecting any information, either by the patient or by the legal representative or by people linked by family ties.  Exclusion Criteria:  Presence of other fractures in the ipsilateral femur that condition the surgical treatment of the pertrochanteric femur fracture. Subcapital fracture of the proximal femur. Subtrochanteric fracture of the proximal femur. Pathological fracture. - HealthyVolunteers: No - Gender: All - MinimumAge: 70 Years - StdAgeList: Older Adult
