A rare case of inflammation after total hip arthroplasty due to a malpositioned prosthesis: A case report

The prevalence and risk factors of dislocation after primary total hip arthroplasty

This study aimed to investigate the occurrence of dislocation and risk factors following primary total hip arthroplasty (THA). Retrospective analysis was done on the clinical data of 441patients with primary total hip arthroplasty who were admitted to our hospital between May 2018 and early December 2020. A total of 294 patients without posterior soft tissue repair were included as control group, and a total of 147 patients with repair of the short external rotator muscle and joint capsule were assigned to the repair group. All operated patients were observed to analyze the occurrence and risk of early postoperative dislocation. Within 6 months after hip arthroplasty, the early hip dislocation rate in the repair group was 0.68%, which was significantly lower than that in the control group (4.78%) (P < 0.05). The results of multifactorial analysis showed that age ≥75 years, combined limb or mental illness, artificial femoral head diameter <30 mm, posterolateral approach and prosthesis placement outside the safety zone, and improper handling were risk factors for dislocation (P < 0.05); The incidence of re-dislocation was lower in the targeted intervention group (P < 0.05). The occurrence of dislocation after THA is related to age, gender, and type of orthopedic disease. The risk factors should be explored to develop targeted intervention protocol, decreasing the dislocation rate and improving the prognosis.

Effect of Operation Room Nursing Intervention and Ceramic Prosthesis on Total Hip Arthroplasty

In order to solve the problems of large trauma, many postoperative complications, and complex operation of artificial hip arthroplasty, a method to analyze the application effect of operating room nursing intervention in artificial hip arthroplasty was proposed. Firstly, 120 patients who underwent hip arthroplasty in our hospital from January to December 2017 were selected; Secondly, they were randomly divided into routine group (60 cases) and intervention group (60 cases); finally, on this basis, the intervention group strengthened the nursing in the operating room and used nanoceramic prosthesis. The Harris score of hip joint, the incidence of postoperative complications, and the satisfaction with nursing services were compared between the two groups. The results showed that the Harris score of hip joint and the satisfaction score of nursing service in the intervention group were significantly higher than those in the routine group (P < 0.05); the incidence of postoperative complications in the intervention group was significantly lower than that in the routine group (P < 0.05). It is proved that actively carrying out nursing intervention in the operating room and using nanoceramic prosthesis can not only improve the clinical efficacy and nursing service satisfaction of patients undergoing total hip arthroplasty but also reduce the incidence of complications.
