Clinical Classification Of The Sequelae Of Hip Infection And Analysis Of Surgical Method Selection

Objective: To summarize patients with a history of hip infection and complications such as secondary osteoarthritis and joint deformity due to infection,and to classify them by differences in clinical characteristics.To help surgeons better assess the anatomical alterations and complexity of the sequelae of hip infection,and thus select the most appropriate treatment modality to relieve patients’ pain and improve their quality of life.Methods: From October 2012 to October 2021,57 patients(65 hips),37 males and 20 females,with a history of hip infection and complications such as hip osteoarthritis,hip dislocation,hip fusion or hip ankylosis were retrospectively analyzed;ages ranged from18 to 59 years,with a mean of 42 years.49 of the patients had a single hip and 8 had a double hip.The patients’ preoperative pain scores were used to assist in the development of treatment plans.Postoperative radiographs were used to assess the efficacy of hip preservation surgery or hip replacement surgery,including the intraoperative acetabular prosthesis coverage and aseptic loosening of the prosthesis in hip replacement patients.The degree of hip destruction and functional limitation was observed according to the Harris score of the hip joint.Results: Of the 57 patients collected,all had infectious lesions in the hip joint,with anatomical changes in the hip joint for up to 10-15 years after the initial infection,including 14 patients with secondary osteoarthritis,21 patients with secondary hip dislocation and 22 patients with fused ankylosis of the hip joint.In conclusion,based on the clinical characteristics of the anatomical changes and symptoms of the hip joint,our group will classify the sequelae of hip joint infection into secondary osteoarthritis type,dislocation type and fusion ankylosis type.Conclusion: The clinical typing of sequelae of hip infection is more intuitive and accurate in describing the characteristics of this type of patients and easy to remember,which can be of considerable help in the selection of the subsequent treatment plan,and can be systematically applied and promoted clinically by combining the anatomical changes and clinical symptoms of the disease.
