Hip replacement is one of the most successful surgeries in the clinic for the removal of painful joints. Hip osteoarthritis and femoral head necrosis are the 2 main reasons for hip replacement. Several factors are associated with the outcomes of surgery. Nonsurgical factors include gender, age, body mass index, prosthetic material, and risk factors. Surgical factors are anesthesia, postoperative complications, and rehabilitation. Considering the increasing demand for hip arthroplasty and the rise in the number of revision operations, it is imperative to understand factor-related progress and how modifications of these fact...

Publication date: Available online 15 April 2019Source: Tribology InternationalAuthor(s): Handong Xu, Dekun Zhang, Kai Chen, Tao ZhangAbstractTo study the fretting tribological behavior of a PEEK hip prosthesis, Ti6Al4V was used as the stem taper material, PEEK was used as the head material, and CoCrMo was used as the contrast material for the PEEK. Fretting friction and wear experiments between the stem taper and head were carried out to demonstrate the feasibility of PEEK as a metal substitute. The results show that the wear values of the Ti6Al4V/PEEK and Ti6Al4V/CoCrMo pairs were all of a small order of magnitude. The T...

Kyoto, Japan-based Kyocera (TYO:6971) said it will buy the major assets of Renovis Surgical Technologies’ artificial joint and spinal products businesses to expand its U.S. footprint. Kyocera will transfer the assets into a new, wholly owned, California-based company to be named Kyocera Medical Technologies in March 2019. Kyocera manufactures medical products, including artificial joints and dental implants, primarily for the Japanese market. The company obtained 510(k) clearance for its artificial hip joints in 2017 and began selling them in the U.S. the following year. Get the full story on our ...

Rationale: Periprosthetic osteolysis secondary to septic loosening and aseptic loosening is a well-described phenomenon associated with artificial hip arthroplasty. Periprosthetic bone loss as a result of metastatic infiltration is an uncommon cause of early, progressive loosening of joint replacement prosthesis and is rarely described in the literature. Patient concerns: The present study describes a 70-year-old male patient who was diagnosed with pulmonary squamous cell carcinoma 5 years after total hip arthroplasty (THA) and developed a metastasis from squamous cell carcinoma in the periprosthetic neosynovial tissu...

Elevating the effectiveness of lubricant to reduce frictional coefficient and wear debris to prolong life time of prosthesis is a main goal. Various biological solvents, such as sodium chloride (NaCl) solution, simulated body fluid (SBF), phosphate buffer solution (PBS) and deionized water, have been investigated to achieve the best stru...

Authors: Lin X, Xu T, Wu B, Hu B, Qin M Abstract The present study was designed to investigate the correlation between glutathione S-transferase M1 (GSTM1) gene polymorphism and the recovery of patients undergoing artificial hip replacement. A total of 241 patients including 149 males (61.8%) and 92 females (38.9%) who received artificial hip replacement in People's Hospital of Rizhao between December 2010 and October 2016 were enrolled to serve as the observation group. Patients were divided into two subgroups according to the loss of GSTM1. A total of 80 healthy subjects who udenrwent a physical examination in ou...
