Challenges Facing Total Hip Arthroplasty (THA)

Total Hip Arthroplasty (THA) is an effective way to reconstruct hip joint osteoarthritis. It has been shown to improve hip joint function and patient's quality of life (1). This program was originally designed for osteoarthritis patients and patients aged 65 years and older. Recent research has expanded the range of age and pathological diagnosis. THA is being offered to young patients and patients with osteonecrosis, rheumatoid arthritis and end-stage arthritis of pediatric hip diseases.

The oldest article at the beginning of the review is irritated. In a randomized controlled trial of Knight and Pellegrini (1996), the use of an indwelling catheter for the treatment of urinary retention during postoperative hip arthroplasty total surgery (THA) or total knee replacement surgery (TKA) It is judged to be beneficial for. In addition, urinary tract infection was judged not to be the result of using indwelling catheter. Although the level of evidence meets the main criteria, the recommended level is D, so the recommendation level is lower, which is better suited to alternative methods for various types of patients requiring urinary catheterization for indwelling urethra There is a possibility

Primary hip replacement surgery is the most common type of total hip arthroplasty. However, frequent types of large-scale orthopedic surgery; in 1998 surgeons with less than 10 people, the mortality rate in the United States increased significantly to 160,000 people. After hip arthroplasty total surgery, less than 10 death hospitals per year are relatively few, indicating 110 complications have increased significantly. At the hospital level, mortality may not be reliable. Empirical evidence suggests that this observational study suggests that the reduction of the indicators is sufficiently accurate and that the original donor has a postoperative mortality rate (average of 1.2% from 0.36% in 1981-1985 and 1987 - 91 The real standard of the year is 0.10). %) Perioperative care changes with a deviation of 5.7%. If the amount of bleeding during surgery decreases,

Guideline hospital quality indicator: quality of care hospital - number, utilization and mortality rate

Two important parameters that affect the stability and lifespan of a metallic hip joint prosthesis in total hip arthroplasty (THA) are the stem length and cross-sectional area. To evaluate their effect on the stress and fatigue behavior of the hip prosthesis a model of a series of hip prostheses with circular or drum shaped cross section and different rod lengths was created. These models are analyzed by finite element analysis under static and dynamic loading conditions and dynamic loading indicates the use of normal walking in dynamic analysis. Stresses of the metal rod, cement and adjacent bone were obtained, and fine movement of the cement-metal interface was also obtained. Safety rate of hip joint prosthesis fatigue life was calculated based on data obtained by dynamic analysis. Dynamic analysis and fatigue analysis showed that the drum stem with a drum height of 10 mm and a stem length of 90 mm had the highest safety factor, and therefore fatigue life was long.
