The TRIGEN™ INTERTAN nail was designed as a trochanteric portal intramedullary nail especially shaped for fractures of the proximal femur. The. INTERTAN. Objectives. To compare the long-term functional and radiographic outcomes of the proximal femoral nail antirotation-Asia (PFNA-II) and. The goal of this study was to compare the outcomes of unstable trochanteric fractures treated with the InterTan nail (Smith & Nephew, Memphis, Tennessee) and.

I have been using a single screw IM device for the last 20 years and have yet to have one cut out. In summary, regardless of the similarity in the final HHS, the most significant finding was that elderly patients with osteoporosis undergoing IT fixation exhibited functional recovery as early as 3 months postoperatively, in contrast to the PFNA-II-treated patients.

Excessive varus forces placed on interran smaller screw at the lateral cortex cause it to toggle and either back out or migrate through the femoral head into the acetabulum. More intramedullary nails and arthroplasties for treatment of hip fractures in Sweden.

Z-Effect is an unfortunate by-product of most intramedually nails that utilize two screws placed up into the femoral neck and head. The larger inferior screw is neither keyed intergan rotation nor locked in place, and it too will either back out or migrate medially.


Internal fixation of intertrochanteric hip fractures: Functional recovery after fracture of the hip.

Recently, a cohort study have demonstrated that there were significant differences between the two groups for complications such as inteftan neck shortening, local complications, fracture healing time and blood loss for unstable intertrochanteric fractures Typically, the superior screw is of smaller diameter than the inferior and bears a disproportionate amount of load during weight bearing.

The INTERTAN system incorporates the best aspects of both devices by providing both single and dual integrated lag screws for the treatment of most major fracture patterns.

Finally, because of the observational nature of this study, we may not have addressed all potential confounding variables in our analyses. Random-effect model was used to explain the statistical heterogeneity.

Using this protocol, however, it was impossible to know when exactly the union had occurred in each patient. Patient-related functional outcomes were evaluated based on the Harris hip score.

Meanwhile, we performed subgroup analysis and sensitivity analysis to interpret the potential source of heterogeneity. The number and combination of screws were the same in each group. Do I have to use the integrated screws? Feb nali ;95 3: Placement of a secondary point of fixation into the femoral neck and head reduces the chances of rotation but adds the secondary concern of Z-Effect.

How is INTERTAN different?

Functional outcome scores were obtained for all patients. Injury ; 45 Suppl 5: Active linear compression helps unload the lateral wall and restore the proximal femur. A randomized prospective comparison of Intertan and Gamma3 for treating unstable intertrochanteric fractures.

J Bone Joint Surg A. Shortening of the femoral neck following peritrochanteric fracture. A prospective clinical study reported that IT showed better clinical outcomes including varus angle, union time, full weight bearing, and cut-out rate than PFNA with 1-year follow-up 9. To intertann sure the extracted data was integrated, we contacted the corresponding authors of the included studies and to get any missing data.

Harris hip score; ASA: Similar mortality rates in hip fracture patients over the past 31 years: The aim of this interta was to describe the results using this device for the treatment of stable and unstable intertrochanteric fractures.
