Femur Transtrochanteric Fractures Treated With Dynamic Hip Screw and Calcium Sulfate Scaffold. (geneX)

Unstable Proximal Femur Transtrochanteric Fractures Treated With Dynamic Hip Screw and ß -Tricalcium Phosphate/ Hemihydrated Calcium Sulfate Graft Scaffold

This is a randomised prospective comparison study to evaluate the incidence of cut - out failure of the dynamic hip screw implant alone compared to the dynamic hip screw adding calcium sulfate through the cervical canal before placing the sliding screw for improvement of the implant stability integration and bone healing.

Transtrochanteric fractures are a frequent entity, mainly in patients over 65 years old, with low bone density. Most of these fractures of the proximal femur are treated effectively with internal fixation with dynamic hip screw (DHS), nonetheless a conditional factor in the treatment success its in the fracture stability and in the osteoporosis severity. There is controversy in the treatment decision in patients with osteoporosis and an unstable fracture added the risk of peri-prosthetic infection or increased bleeding during surgery means that the decision to place a DHS versus a prosthesis is debated. This study represents the first comparison of closed reduction and internal fixation with DHS using calcium sulfate graft versus conventional DHS procedure.

Participants in which absorbable graft of tricalcium ß phosphate / calcium sulfate hemihydrate paste at the time of the placement of the hip implant to prevent loosening of it's unstable trans-trochanteric fractures of the proximal femur, were applied.

Application of absorbable graft of tricalcium ß phosphate / calcium sulfate hemihydrate in paste for prevent loosening of Dynamic Hip Screw implant

Incidence of cut - out failure of the dynamic hip screw implant in unstable transtrochanteric fractures

The aim of this study is to evaluate the incidence of cut - out failure of the dynamic hip screw implant alone compared to the dynamic hip screw adding calcium sulfate through the cervical canal before placing the sliding screw to improve implant integration and bone healing.

Inclusion Criteria: Patients between 65 and 80 years old Patients classified as 31A1.3 and all 31A2 by the Orthopaedic Trauma Association classification system. Exclusion Criteria: Patients with stable hip fractures Participants who do not accept the randomization process patients who do not complete follow-up during the study
