“…11 In these elderly patients, early postoperative weight bearing often leads to impaired mobility and delayed weight bearing and may further weaken the bone, culminating in a dissatisfactory result. 1 , 3 Although numerous studies of fixation with the IT and PFNA-II that were primarily based on short-term (≤1 year) evaluation indicators such as the operation time, length of stay, blood loss, fluoroscopy time, and pain demonstrated that both nails achieve good functional and radiographic outcomes, 3 , 12 – 14 few studies have compared both nails in the management of IFFs (AO/OTA Type 3.1A1.1-A2.3) in terms of long-term functional and radiographic outcomes in elderly patients with osteoporosis. Thus, conclusive data regarding which implant is more advantageous are lacking in this area.…”

ObjectivesTo compare the long-term functional and radiographic outcomes of the proximal femoral nail antirotation-Asia (PFNA-II) and INTERTAN nail (IT) in the management of intertrochanteric femoral fractures (IFFs) (AO/OTA Type 31A1.1-A2.3) in elderly patients with primary osteoporosis.MethodsA retrospective comparative study was performed in our institution. From January 2009 to March 2012, 243 patients with osteoporosis (243 hips) with IFFs (AO/OTA Type 3.1A1.1-A2.3) underwent repair with either a PFNA-II or IT. Follow-up assessments were performed 1, 3, 6, 9, and 12 months postoperatively and every year thereafter. All implant position changes were noted. Patient-related functional outcomes were evaluated based on the Harris hip score.ResultsIn total, 174 patients with osteoporosis (IT, n = 86; PFNA-II, n = 88) were evaluated during a mean follow-up period of 40 months (range, 38–60 months). An increased risk of femoral shaft fracture after implant removal was observed at month 9 of follow-up in 0.0% and 4.4% of the IT and PFNA-II groups, respectively. This difference remained over time with rates of 1.1% and 6.8%, respectively, at the last follow-up.ConclusionThe IT nail appears to be a reliable implant in the management of IFFs (AO/OTA Type 3.1A1.1-A2.3) in elderly patients with primary osteoporosis.

“…PFNA-II can minimize the risk of these implant-related complications and provide angular and rotational stability. This is especially important in osteoporotic bone and unstable IFFs of elderly high-risk patients, allowing early mobilization and weight bearing on the affected limbs [ 15 – 18 ]. The literature reports that the biomechanical stability of PFNA-II is superior to that of DHS [ 17 , 19 ].…”

BackgroundThe purpose of this study was to evaluate whether PFNA-II (Asia proximal femoral nail anti-rotation) and DHS (dynamic hip screw) carry substantial post-operative hidden blood loss and to compare PFNA-II with DHS in terms of post-operative hidden blood loss in elderly high-risk patients with intertrochanteric femur fractures(IFFs).MethodsThe clinical data from Jan 2005 to Apr 2015 of 186 patients with PFNA-II and 177 patients with DHS were analyzed retrospectively. Indexes including pre- and post-operative blood routine, intra- and post-operative blood loss and blood transfusion situation were analyzed. The situation of perioperative blood loss (visible and hidden) was assessed.ResultsThe intra-operative blood loss in the PFNA-II group was 34.7 ± 2.5 ml, the post-operative visible blood loss was 54.7 ± 2.5 ml, and the hidden blood loss was 277.2 ± 7.6 ml. In the DHS group, the intra-operative blood loss was 102.0 ± 7.0 ml, the post-operative visible blood loss was 78.8 ± 4.7 ml, and the hidden blood loss was 139.3 ± 9.6 ml. The intra-operative blood loss and the post-operative visible blood loss in the PFNA-II group were significantly less than in the DHS group (p < 0.01). However, the post-operative hidden blood loss and the total blood loss in the PFNA-II group were larger than in the DHS group (p < 0.01).ConclusionThis study demonstrated that with PFNA-II and DHS, much post-operative hidden blood loss exists in the treatment of intertrochanteric fractures in elderly high-risk patients and DHS is more favourable than PFNA-II in terms of post-operative hidden blood loss.

“…In view of these facts mentioned earlier and also as a part of our work on the synthesis of bioactive lead compounds, the title compounds were designed by introducing cyclopropane and 1,2,3‐thiadiazole pharmacophore into 1,2,4‐triazole scaffold. Some 1,2,4‐triazole derivatives were synthesized and characterized by 1 H‐NMR, MS, and elemental analysis.…”

Starting from carbonic acid diethyl ester, a series of 1,2,4‐triazole derivatives containing 1,2,3‐thiadiazole were synthesized. Reactions were performed by microwave irradiation or ultrasonic irradiation as well as by conventional heating. The structure of title compounds was characterized by 1H‐NMR, MS, and elemental analyses. The fungicidal activities of these compounds were tested in vivo. Most of title compounds exhibited good antifungal activity against Pseudoperonospora cubensis. Some of title compounds displayed moderate antifungal activities against Fusarium oxysporum, Pseudoperonospora cubensis, Sphaerotheca fuligenea, Corynespora cassiicola, and Xanthomonas axonopodis.
