INTERTAN NAIL PDF


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.

Twelve months postoperatively, the implant was removed in each patient. If there were disagreements between two authors, consensus was reached through discussion. Inhibition of fracture healing.

A prospective randomized study reported that there were no significant difference in mean hospital stay between IT 8. Inntertan fractures in seniors: In addition, elderly patients with osteoporosis are more prone to screw movement nnail cutting of screws into the femoral head, which can result in fixation failure. Watch video of head rotations with a conventional single lag screw device The INTERTAN nail solves that problem by integrating two screws so that they function as one unit to prevent nai, and excessive screw migration.

Clinical and functional outcomes of internal fixation with intertrochanteric antegrade nail in older patients with proximal extracapsular femoral fractures. 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.

If I only use the single subtrochanteric lag screw option does that create a stress riser at the empty inferior hole in the nail? 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.

Data are presented as n. The InterTan IT nail system, introduced inhas been reported superior biomechanical and clinical outcomes compared with 1-screw nailing system. Proximal femoral nails antirotation, Gamma nails, and dynamic hip screws for fixation of intertrochanteric fractures of femur: Table 1 The characteristics of included studies. Biomechanical evaluation of interlocking lag screw design in intramedullary nailing of unstable pertrochanteric fractures.

Follow-up visits occurred at 1, 3, 6, 9, and 12 months postoperatively and every year thereafter.

How is INTERTAN different?

This makes medial migration and the Z-effect nearly impossible. Yu W, et al. Plain radiographic outcomes anteroposterior and lateral projections were obtained at each visit. First, the small sample size may have introduced bias. Orthop Traumatol Surg Res ; Secondary outcomes Union time Data from five studies with patient reported the union time.

White Paper Screw Comparison. Hsueh K, Fang C. Do PFNA devices and Intertan nails both have the same effects in the treatment of trochanteric 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.

Similar mortality rates in hip fracture patients over the past 31 years: Internal fixation of intertrochanteric hip fractures: 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.

Although some limitations exist in our study, relevant articles have been stringently screened according to the inclusion and exclusion criteria and the extracted data are of high quality.

The resultant Z-Effect where the two screws move in opposite directions is one mode of failure for the conventional two screw reconstruction device. Statistical analyses were performed using SPSS version The Journal of bone and joint surgery.

Typically, the superior screw is of smaller diameter than the inferior and bears a disproportionate amount of load during weight bearing. Data from five studies with patient reported the union time. 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. INTERTAN provides significantly greater fracture compression and reduced femoral shortening than a helical blade cephalomedullary nail.

All the included articles were published between and RCTs or prospective cohort studies or retrospective cohort studies with prospective collected data. J Nat Sci Biol Med. The results of in vitro simulation testing have not been proven to predict clinical performance.

Clinical evaluation of the Asian proximal femur intramedullary nail antirotation system PFNA-II for treatment of intertrochanteric fractures.

A call for health system reform.

Six of 88 6. Atkins D, et al. Hip fracture in seniors: J Orthop Trauma ; However, less surgery time was used in 1-screw nailing system. Trapezoidal nail shape Small proximal diameter of the nail Revision surgery was performed as quickly as possible, without waiting for the situation to further deteriorate.

J Bone Joing Surg Br. Nuchtern JV, et al. Watch video of head rotations nwil a conventional single lag screw device. Although, IT shows less implant cut-out and femoral fractures.

The nail’s shape in association with the smaller entry portal give it enhanced rotational stability within the proximal femur. All implant position changes were noted.
