[Effectiveness of medial open wedge high tibial osteotomy combined with posterior slope angle of tibial plateau correction in treatment of osteoarthritis of limited flexion knee with varus deformity].

Objective: To explore the short-term effectiveness of medial open wedge high tibial osteotomy (OWHTO) combined with posterior slope angle of tibial plateau correction to treat the osteoarthritis of limited flexion knee with varus deformity.

Methods: The data of 18 cases (18 knee) with osteoarthritis of limited flexion knee with varus deformity between January 2014 and July 2016 were analyzed retrospectively. There were 6 males and 12 females with an average age of 54.

Improved radial distribution functions for Coulomb charged fluid based on first-order mean spherical approximation.

In this work, we solve the Ornstein-Zernike equation in a simple, analytical, and consistent manner to obtain the like and unlike radial distribution functions (RDFs) for charged fluids. To improve mean spherical approximation (MSA) solutions, the direct correlation functions both for the density and charge contributions are modified with the Yukawa potential, respectively. On the basis of the contact values of RDFs and excess internal energy of the system, we construct correlated equations to cope with the potential parameters.
