First results with the trochanter fixation nail (TFN): a report on 120 cases.
ABSTRACT A complication rate between 4-18% for the conventional osteosynthesis of the proximal femur fracture continues to be unacceptable even if increasing age and co-morbidity of patients are taken into account. Therefore, new intramedullary techniques are under development, and we here report our results with the novel trochanteric fixation nail (TFN). During the study period (March 2003-February 2004) all patients with a trochanteric fracture Type A1-A3 (AO/ASIF classification) were eligible for the study, and 120 patients (mean age 81 years, range 47-100; male/female 1:4) subsequently enrolled. Most frequent was the (according to the AO classification) A.2.1. type of fracture (n=39) and the A.2.2. fracture (n= 39). Operation time from cut to stitch was 45 mins (minimal 21/maximal 194). Thirty-seven (31%) postoperative X-rays were classified as very good, 60 (50%) as good, 18 (15%) as satisfying and five (4%) as bad post-reposition results according to the Garden Alignment Index. The clinical results were documented by the time of hospital stay, postoperative mobilization and time of rehabilitation compared to the old social status. Time to hospital discharge was 17 days (9 /25). Overall complication rate was 7.5% (9 patients) with 5.8%  local wound infection; 1.6%  cutting out of the helical blade through the cortex of the femoral head. We had three (2.5%) hospital deaths in our patient group. We conclude that TFN is a safe and reliable technique. Compared with techniques like PFN and Gamma-nail, clinical results are excellent with less complications.

ABSTRACT: A reflective type VOA is demonstrated in this paper. The VOA MOEMS device comprises two parts, electrode and mirror, and bonding by solder. The mirror part is made by SOI wafer to get excellent reflective plane. This VOA operates below at 1OV for 45dB attenuation with good optical performance, low insertion loss, low PDL 0.2dB@15dB, and low WDL 0.7dB@15dB.01/2005;

ABSTRACT: Subtrochanteric femoral fractures are expected to increase in the coming years. Despite the improvement of implants and surgical techniques, failures due to complications are still considerable. This article reports a retrospective review of patients who showed a subtrochanteric femoral fracture and who were treated consecutively with the Long Proximal Femoral Nail (LPFN) from January 2001 to August 2004, or with the Long Trochanteric Femoral Nail (LTFN) from January 2005 to January 2008. A total of 43 patients with 44 subtrochanteric femoral fractures were included in the study: 23 were treated with the LPFN and 21 with the LTFN. The number of complications related to the LPFN was eight (two re-interventions) against only one related to the LTFN (no re-interventions). haemoglobin decrease was on average higher in the group treated with the LPFN (35.5g/L) than with the LTFN (30.4g/L), and so was the number of patients needing for red blood cell concentrates transfusion (15 and 9, respectively). Mortality at the sixth-month follow up was higher in the group treated with the LTFN. The average surgery time was similar in both groups. The percentage of patients capable of walking within the first postoperative week was similar in both groups as well as time to discharge and the consolidation time. Both the LPFN and the LTFN are reliable implants for the treatment of subtrochanteric fractures of the femur. New features related to the LTFN might decrease the number of complications as well as the need for red blood cell concentrates transfusion.
