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.

The clothespin distal tip of the INTERTAN short nail reduces the overall cross-sectional stiffness of the implant to minimize the risk of iatrogenic fracture during insertion, to ease the actual process of nail insertion and to offer enhanced rotational stability within the proximal femoral canal.

Biomechanical evaluation of interlocking lag screw design in intramedullary nailing of unstable pertrochanteric fractures. Erez O, Dougherty PJ. Do PFNA devices and Intertan nails both have the same effects in the treatment of trochanteric fractures?

What is an Integrated Interlocking Screw configuration and how will it help my patients? Watch video of head rotations with a conventional single lag screw device.

Predictors of failure intrtan cephalomedullary nailing of proximal femoral fractures. Declaration of conflicting interest The authors declare that there is no conflict of interest.

There are still controversies about the kntertan implant system to stabilize unstable intertrochanteric fractures, especially in the elderly patients with osteoporosis. Malpositioning of the lag screws by 1- or 2-screw nailing systems for pertrochanteric femoral fractures: Internal fixation of intertrochanteric hip fractures: Secondary outcomes Union time Data from five studies with patient reported the union time.


naail It was not clear whether IT can provide better clinical outcomes. These rates differ from two other studies that reported rates of Nuchtern JV, et al.

Complications Complications were reported in all the included nine studies. Assessment of reporting bias We used funnel plot to evaluated reporting biases qualitatively.

Although ibtertan findings from the intermediate months could not be explained at the 1-year follow-up, no significant differences in the return nitertan prefracture ambulatory levels and independence were observed between the two groups. The choice of equipment size was based on the condition of the femur. J Bone Miner Res. 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.

Significant differences were found in IT vs. Excessive varus forces placed on the smaller screw at the lateral cortex cause it to toggle and either back out or migrate through the femoral head into the acetabulum.

There were no other significant differences in the remaining observation indices between the two groups Table 4. American Academy of Orthopaedic Surgeons.

Journal of orthopaedic trauma. All Trademarks acknowledged This information intended for U. When the quality score was greater than five points, the included studies were considered to be of high quality The INTERTAN system incorporates aspects of both devices by providing both single and dual integrated lag screws for the treatment of most major fracture patterns.

However, IT group showed less implant cut-out and femoral fractures than 1-screw group. Rigid fixation is critical for minimizing interfragmentary motion and maintaining fracture reduction under load. Functional recovery of elderly patients with surgically-treated intertrochanteric fractures: For additional questions, please contact your local sales representative.

Its lower coefficient of friction facilitates superior sliding of the lag screw within the barrel of the nail relative to other single screw devices to promote fracture healing. Shortening of the Femoral Neck. Proximal femoral nails antirotation, Gamma nails, and dynamic hip screws for fixation of intertrochanteric fractures of femur: Six weeks postoperatively, the patients were permitted to ambulate with partial weight bearing.

Open in a separate window. A systematic review of RCTs. A low-molecular-weight heparin sodium injection enoxaparin [Clexane] aXa IU; Shanghai, China was administered to all patients once a day beginning on the day of admission and continuing for 7 subsequent days, and all patients received a prophylactic antibiotic cefazolin sodium pentahydrate, 2. Meta-analyses was performed with Review Manager 5.

Finally, 9 91016 — 22 articles with patients that compared 2-screws with 1-screw intramedullary nail were included. The resultant Z-Effect where the two screws move in opposite directions is one mode of failure for the conventional two screw reconstruction device.

How is INTERTAN different?

Does the implant make the difference? Osteoporotic pertrochanteric hip fractures: In addition, the nail’s trapezoidal profile also provides enhanced anatomical fit and added rotational stability in the proximal femoral metaphysis similar to that offered by conventional hip stems. The HHS was used to assess the functional outcome of the patients. A systematic review and meta-analysis was conducted to identify all studies from data base involving IT and conventional intramedullary nails for intertrochanteric fractures in electronic databases including Web of Science, Embase, PubMed, the Cochrane Controlled Trials Register, and the Cochrane Library up to May Rueger J, Moore C.
