“…According to Klug et al in 2019, based on a 10-year analysis of studies in Germany, over 50% of all performed surgeries were total cementless hip arthroplasty using a classic stem. The database analyzed in the above study did not include the evaluation of femoral neck arthroplasty [ 5 ].…”

Background Oxidative stress is a disruption of the pro-oxidative-antioxidant balance, caused by excessive production or ineffective removal of reactive oxygen species. Material/Methods The study included 42 male patients aged 38 to 69 years. The first group consisted of 21 men with osteoarthritis after primary hip arthroplasty using the Smith & Nephew Birmingham Hip Resurfacing implant. The second group included 21 men after hip arthroplasty using the femoral neck SPIRON K-implant. In both groups, concentrations of ions, the antioxidant system in the blood, and parameters of oxidative stress were evaluated twice. Clinical assessment using the Western Ontario and McMaster Universities Osteoarthritis Index, Harris Hip Score, and Short Form (12) Health Survey (SF-12) scales was performed. Results Concentrations of metal ions in the blood and the level of oxidative stress were significantly higher in the resurfacing group than in the femoral neck arthroplasty group. The response of the antioxidant system was significantly greater in the femoral neck arthroplasty group. During clinical evaluation, groups did not show significant differences, with the exception of greater shortening of the operated limb and a lower score in the mental-sphere of the SF-12 scale in the resurfacing arthroplasty group. Conclusions Resurfacing hip arthroplasty increased oxidative stress, increased the concentration of metal ions, and did not affect alignment of the abbreviation of the operated limb. A significant improvement in the quality of life of patients in the mental sphere according to the SF-12 occurred after the application of resurfacing arthroplasty, in the first month after the procedure.

Hip dysplasia is a congenital defect of the hip joint in infants with mismatch of the femoral head and the acetabulum. It can be treated in infants via conservative or surgical containment of the femoral head. In developing countries cases of hip dysplasia are often overlooked and neglected. Therefore, many cases of severe coxarthrosis with dislocations of the femoral head can be observed. The dislocation complicates the implantation of a hip prosthesis. This article shows a novel technique in total hip replacement in a case report.

“…Modern hip arthroplasty is prone to fretting and corrosion at the taper junction for three reasons. First, procedures are increasingly being performed through small incisions [85], which may impair the proper cleaning and drying of the taper due to reduced exposure. Secondly, driven by the trend to increase the range of motion, there has been a reduction in the diameter of the neck and of the length of the tapers, which reduces flexural rigidity [65,73].…”

What the Surgeon Can Do to Reduce the Risk of Trunnionosis in Hip Arthroplasty: Recommendations from the Literature

Trunnionosis, defined as wear and corrosion at the head-neck taper connection, is a cause of failure in hip arthroplasty. Trunnionosis is linked to a synergistic combination of factors related to the prosthesis, the patient, and the surgeon. This review presents analytical models that allow for the quantification of the impact of these factors, with the aim of providing practical recommendations to help surgeons minimize the occurrence of this failure mode. A tighter fit reduces micromotion and, consequently, fretting of the taper connection. The paramount parameters controlling the fixation force are the coefficient of friction and the impaction force. The influence of the head diameter, as well as of the diameter and angle of the taper, is comparatively small, but varus alignment of the taper and heads with longer necks are unfavourable under physiologic loads. The trunnion should be rinsed, cleaned, and dried carefully, while avoiding any contamination of the bore-the female counterpart within the head-prior to assembly. Biological debris, and even residual water, might critically reduce the fixation of the taper connection between the head and the neck. The impaction force applied to the components should correspond to at least two strong blows with a 500 g hammer, striking the head with an ad hoc impactor aligned with the axis of the taper. These strong blows should correspond to a minimum impaction force of 4000 N.
