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.

We used the inverse variance and Mantel—Haenszel methods to combine separate statistics. All implant position changes were noted. Indian J Orthop ; Clothes pin distal tip Less rigid than conventional devices Reduces the incidence of anterior thigh pain Reduces chance for secondary femoral shaft fractures.

The funnel plot was symmetric Supplemental Fig. The visible and hidden blood loss of Asia proximal femoral nail anti-rotation and dynamic hip screw in the treatment of intertrochanteric fractures of elderly high- risk patients: A previous clinical study reported that IT showed good clinical outcome and low complication rate in Asian patients The trapezoidal shape of the nail places more material at the lateral side of the implant where tensile forces are typically the strongest.

There were no other significant differences in the remaining observation indices between the two groups Table 4. Clinical evaluation of the Asian proximal femur intramedullary nail antirotation system PFNA-II for treatment of intertrochanteric fractures.

Comparison of clinical outcomes with three different intramedullary nailing devices in the treatment of unstable kntertan fractures. Placement of a secondary point of fixation into the femoral neck and head reduces the chances of rotation but adds the secondary concern intertsn Z-Effect. 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.


Our designing surgeons feel that rotational instability is a major contributing factor to that failure rate and propose the INTERTAN nail as the solution to this dilemma.

Trapezoidal nail shape Small proximal diameter of the nail Injury ; 45 Suppl 5: Poor functional outcomes Solution: Materials and methods Study population This study was reviewed and approved by the review board of the First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China, and exemption for informed consent was obtained from the Investigational Ethical Review Board.

Lower risk of implant failure and non-union 6,7,8,9,10,11,12,13,14, This was consistent with our findings. This has the advantage of lessening point stresses about the distal tip of the nail najl reducing the possibility of fracture due to a stress riser at that location. Acta Orthopaedica ; 85 1: All incisions were closed in layers.

Acta Orthop Belg ; A retrospective analysis of the InterTan nail and proximal femoral nail anti-rotation-Asia in the treatment of unstable intertrochanteric femur inteetan in the elderly. Case Study- 48 YOM with a Peritrochanteric Hip Fracture Cephalomedullary nailing and intraoperative compression of a peritrochanteric hip fracture year-old male, injured in a fall causing a two-part peritrochanteric hip fracture.

Rueger J, Moore C.

The state of the art in 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. Implant failure was defined as any condition that would necessitate revision surgery with a change of implant. Change location South Africa – New.

Internal fixation of pertrochanteric fractures using DHS with a two-hole side-plate. The resultant Z-Effect where the two screws move in opposite directions is one mode of failure for the conventional two screw reconstruction device.


Despite our consistent findings among different orthopedic departments, there are several limitations to our study. All the included nine studies assessing patients reported the HHS postoperatively.

How is INTERTAN different?

Union was defined as clear demonstration of bone bridging across the fracture on radiographs with the ability to bear full weight on the extremity and evidence of clinical healing i. When an IFF occurs and an implant is applied, the occurrence of a decisive difference in outcome cannot be automatically evaluated based on factors such as the operation time, length of stay, blood loss, fluoroscopy time, or short-term pain because numerous subjective and objective factors influence these parameters.

A study in Asian population. Length of hospital stay Five articles with patients showed the outcome of length of hospital stay. The results of inertan vitro simulation testing have not been proven to predict clinical performance.

Secondly, the follow-up of patient is different between included articles. Osteoporosis may also lead to technical problems during the procedure. Please contact your local rep for additional information or fill out our contact us form.

The Treatment of Intertrochanteric Fractures: In addition, compliance of HHS for elderly population specially intdrtan patients with dementia should be considered. Three days postoperatively, the patients were encouraged to engage in partial weight-bearing ambulation. Supplementary information accompanies this paper at The 17mm reamer is available to accommodate those instances when dense bone is encountered such that it precludes that initial press-fit.
