Laboratory analysis and data were provided by our centralized implant retrieval laboratory, the. The tension-to-tension fatigue strengths of annealed Ti-6Al-4V, V-free Ti-6Al-7Nb, Ti-6Al-2Nb-1Ta, and Ti-15Mo-5Zr-3Al alloys at 1×108cycles were approximately 685, 600, 700, and 350MPa, respectively. failure, it was noted that the majority of the patients, in fact, had well-reduced fractures at the time of the index surgery. Centre for Implant Technology and Retrieval Analysis (CITRA), Western Australia. In this study, we use ab-initio calculations to investigate the Mo-Ti phase diagram.

Initial viscosity of TRAUMACEM V+ Injectable Bone cement allows for cement injection immediately after mixing with no wait time. (ABSTRACT TRUNCATED AT 250 WORDS). It incorporates the best elements of our highly successful global hip nails (TFN, PFNA*, and PFNA II*), optimized through input from hundreds of surgeons around the world. chanteric Fixation Nail]-Advanced; DePuy Synthes) was intr, to the global market in 2015 and is made from a titanium-, locally and internationally. Laboratory review of retrieved implants was conducted at the Centre for Implant Technology and Retrieval Analysis (CITRA) in Western Australia.

Cost data concerning the index hospitalisation were pooled, and a meta-regression was used to examine its potential drivers. Of 8 patients treated with a second TFNA implant for nail breakage, 3 (38%) returned with breakage of the revision implant. In a multicentre prospective clinical study, the intra-operative use, complications and outcome of treatment using the PFN (n = 211) were compared with those using the gamma nail (GN) (n = 213). This study represents the largest series, to our knowledge, of proximal femoral nail breakages in the published English literature and is the first that we are aware of to involve laboratory analysis of the TFNA implant. After a series of cases involving implant breakage were re-, ported at the orthopaedic trauma units in W, study was initiated to investigate the patient and surgical charac-. The TiMo alloy of the nail conforms to ASTM, 2066 (ASTM International) and can be manipulated by, processing conditions to produce these various structures, beta), which is indicative that the alloy had been worked in, some way, as expected in the production of an intramed-, Microhardness was evaluated by sequential testing traversing, from the outer to the inner diameter. SEM of the fracture surfaces was confounded by the tortuous, contrast to the more commonly observed plan, noticeable surface ridge was also present, which corresponded, nail breakages in the published English literature and was the, of the TFNA implant. Choice of both TFNA Helical Blade or TFNA Screw to suit a wide variety of clinical needs, which supports surgical preferences and helps facilitate hospital standardization. 4 DePuy Synthes TFNA – Proximales Femur-Nagelsystem Operationstechnik AO PRINZIPIEN 1 Müller ME, Allgöwer M, Schneider R, Willenegger H (1995) Manual of Internal Fixation. Total costs including prevalent fractures are more than $19 billion. Total costs by fracture type were vertebral (6%), hip (72%), wrist (3%), pelvic (5%), and other (14%). This site is published by the DePuy Synthes Companies, which are solely responsible for its content. The, This study represents the largest series, to our knowledge, of proximal femoral nail breakages in the, rst that we are aware of to involve laboratory analysis of the TFNA implant. Total incident fractures by skeletal site were vertebral (27%), wrist (19%), hip (14%), pelvic (7%), and other (33%). Long nail provides three distal locking options, including a oblique distal hole that is offset an additional 10° to target bone in condyles. The unique sets of bone and soft tissue abnormalities that must be addressed at the time of the operation make accurate axis restoration, component orientation and joint stability attainment a difficult task. Hofmann L. AO Foundation: Final Report for biomechanics evaluation of a non-augmented nail head element in surrogate femoral heads [Synthes GmbH:USTRA09022 Trochanteric Fixation Nail-Advanced (TFNA)] 2015.

The TRAUMACEM V+ is a polymethylmethacrylate (PMMA) cement with specific indications for augmentation of a trauma device, allowing surgeons to inject a controlled amount of cement into the femoral head in patients with poor bone quality, reducing the risk of cut-out. patient mortality as well as high economic burden. Complications of femoral pertrochanteric fractures treated with. Photograph of the anterior surface of the proximal portion of a broken nail. Osteoporosis prevention, treatment, and education efforts should address all skeletal sites, not just hip and vertebral, and appropriate attention is warranted for men and diverse race/ethnicity subgroups. Patients developing complications as well as patients enrolled in intervention arms of comparative studies were found to have significantly higher costs compared to the controls. The TFNA System is designed to advance the treatment of trochanteric fractures by providing surgical options that help to preserve bone in insertion area due to reduced critical width, improve anatomical fit1 and increase implant strength.2 It is designed to reduce the risk of cut-out,3,4 distal cortical impingement1 and nail breakage,2 which are common post-operative complications.5,6,7 Several clinical studies have published reporting favourable outcomes in cut-out resistance.8-10*, LATERAL RELIEF CUTTM & Small Proximal Diameter. All Rights Reserved. In 11 cases, breakage was treated with a revision nail: the TFNA implant, was used in 8 of these revision cases; the AFN (Antegrade, Femoral Nail; DePuy Synthes), in 2 cases; and the PFNA, (Proximal Femoral Nail Antirotation; DePuy Synthes), in, 1 case. These include: detailed data on the microscopy of the junctional tissues, the mechanical properties of cement, and the architecture of bone and implant design.
