BACKGROUND: Volar Barton’s fracture is a shearing mechanism of injury that results in fracture and subluxation of distal end radius in which volar rim of the distal radius is displaced with hand and carpus. Open reduction and volar plate fixation ensure more stable change of displacement, preservation of reduction, and early mobilization. AIM: This study aims to assess the functional and radiological outcome results of volar Barton’s fracture treated by volar buttress plate using the demerit points system of Gartland and Werley. PATIENTS AND METHODS: This study is a prospective descriptive observational study on 32 patients who were treated with ORIF by volar buttress plate for isolated volar Barton’s fractures between February 2018 and June 2020 in Alkindy teaching hospital/Baghdad/Iraq. All volar Barton’s fracture cases satisfying the inclusion criteria which included patient over 18 years, isolated fracture, medically fit, and <5 days old injuries, while fractures extend to radius shaft, compound fractures, and associated with other injuries were excluded from the study. All fractures are fixed by volar locked plate followed up for 12 week’s duration for functional and radiological assessment using the Demerit points system of Gartland and Werley. RESULTS: Most cases were in the age group below 40 years, average age 38 years (range 19–64 years), male patient was 69%, side of involvement was right wrist in 75% of cases, falling on an outstretched hand account 50%, while roads traffic accidents in 37.5%, fall from a height in 6.25%, and direct trauma in 6.25%. The final sequel of the results was average volar tilt was 11.1°, the radial shortening average was 4 mm, the radial inclination average was 19.9°, and the ulnar variance was 0.3 mm. Functional outcomes depending on Gartland and Werley’s score were 50% as excellent results, 43.75% as good results, 6.25% as fair results, and no poor results in this study. CONCLUSIONS: Volar locking buttress plate provides fracture stability and early mobilization, therefore, recovery of daily live activity in a short time.
This paper presents a new Azo dye that was prepared from the reaction of the Benzene-1,2-diamine and 1-(2,4,6-Trihydroxy-phenyl)-ethanone, Azo dye was used to prepare a new series of complexes with general formula: [Co2(H4L) Cl2(H2O)4] and [M2(H4L)Cl4(H2O)2] (M= Cr+3, Fe+3,Rh+3 and Ru+3). The prepared materials were different measurements including to infrared, ultraviolet-visible, and mass spectrometry, as well as thermo gravimetric analysis, differential calorimetry, and elemental analysis. Conductivity, magnetic susceptibility, metal content, and chlorine content of the complexes were also assessed. The complexes prepared from the dye were used to determine their ability to inhibit free radicals by measuring their antioxidant capacity us

The aim of this study was to compare the prepared canal transportation and centering ability after continuous rotation or reciprocation instrumentation in teeth accessed through traditional or conservative endodontic cavities by using cone-beam computed tomography (CBCT).

Bipedal robotic mechanisms are unstable due to the unilateral contact passive joint between the sole and the ground. Hierarchical control layers are crucial for creating walking patterns, stabilizing locomotion, and ensuring correct angular trajectories for bipedal joints due to the system’s various degrees of freedom. This work provides a hierarchical control scheme for a bipedal robot that focuses on balance (stabilization) and low-level tracking control while considering flexible joints. The stabilization control method uses the Newton–Euler formulation to establish a mathematical relationship between the zero-moment point (ZMP) and the center of mass (COM), resulting in highly nonlinear and coupled dynamic equations.
