Background: The choice of the appropriate operative intervention in patients with late and neglected hip fracture continuous to be a huge dilemma for orthopedic surgeons. Purpose: To evaluate the satisfaction or otherwise of some treatment options using the modified Harris-hip score (HHS) in resource poor setting. materials and methods: A retrospective cross-sectional study conducted at ATBUTH, Bauchi. Data of 60 patients over the age of 18 years with hip fractures (femoral neck, intertrochanteric and sub trochanteric fractures) who had operative intervention between 1st September 2019 and 31st August 2020 with cannulated screws, Proximal femur lock compression plate (PFLCP), cementlessor cemented bipolar hemiarthroplasty (BHA). Results: The mean age of studied patients was 65.7 ± 16.1 years, with age ranging from 19 - 101 years. m:F ratio was 1.2:1 across all age groups and 1:1.4 amongst those >60 years. 51 patients (85%) presented > 1 week after injury with 24 patients (40%) sustaining hip fractures from low energy trivial indoor fall and 28 patients (46.7%) mostly younger sustaining fractures from high energy motor vehicular accident (mVA). The prevalence rate for femoral neck, intertrochanteric and subtrochanteric fractures were 32 (53.3%), 17 (28.3%) and 11 (18.3%) respectively. From the data retrieved, 21patients (35.0%), 17 patients (28.3%), 20 patients (33.3%) and 2 patients (3.3%) had PFLCP, cemented BHA, cementless BHA and cannulated screw fixation respectively. most (66.7%) of those who had PFLCP achieved satisfactory radiologic union and there was also 94.1% and 85% satisfactory outcome rate amongst the patients with cemented BHA and cementless BHA respectively. Irrespective of the operative intervention method at 1 year follow-up, there was a statistically significant improvement in post-operative HHS (P value 0.02), with 83.4% having good to excellent results. Conclusion: There is highrate of late and neglected hip fracture in our environment. Satisfac

Engineering of efficient visible light photocatalysts:Ti_(1-x+y)Cu_(x)La_(y)O_(2)(x=0.03;y=0,0.005,0.01) compositions

In dye-photocatalysis, widening the wavelengths absorption range of catalysts as well as aborting the recombination of the photoexcited charge carriers(electrons-holes pairs) are of paramount *** the current study, we report the photocatalytic characteristics of four compositions composed of TiO_(2),Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders for two harmful dyes(Congo red and methylene blue). The X-ray diffraction technique verified the configuration of mixed anatase and rutile phases in pure TiO_(2)and Ti_(0.97)Cu_(0.03)O_(2)powders while Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders possess anatase phase only. The changes of the band gap structure and dimensions of the unit cell volume of TiO_(2)confirm the substitution of Ti^(4+)sites by Cu^(2+)and La^(3+)ions. Remarkable widening of wavelengths absorption with formation of long absorption tails were found in TiO_(2)(3.13 e V) through insertion of La^(3+)plus Cu^(2+)ions. Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)samples exhibit a visible light band gap of 2.3 and 2.7 e V, respectively. Based on SEm images, incorporation of Cu^(2+)and La^(3+)ions influences the surface morphology of TiO_(2). The resulting Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders present enhanced photocatalytic activity towards Congo red dye degradation compared to pure one under natural solar spectrum. The best Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst exhibits superior photocatalytic activity of 96% for 10 ppm CR dye in 20 min as well as above average photocatalytic efficiency of 63% for 30 ppm CR dye in 120 min. As well, it showed acceptable photodegradation activity of 52% for 30 ppm mB solution in 140 min of sunlight irradiation. The heightened photodegradation efficiency of Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst can be clarified in terms of higher ch
