Abstract：BACKGROUND:Due to the continuous development of medical technology and prosthetic material study, patients with ankylosing spondylitis-associated hip joint lesion are often treated with artificial total hip arthroplasty. Because the majority patients of this kind of disease are young patients, it is of great importance for the patients’ life quality through maximizing the recovery of hip function, restoring the biomechanical balance of spine, pelvis and hip joint and prolonging the life of hip joint. OBJECTIVE:To observe the repair effect of total hip arthroplasty in treatment of ankylosing spondylitis-associated hip joint lesion based on the biological level. METHODS:Total y 60 patients with ankylosing spondylitis-associated hip joint lesion who received the treatment at Department of Joint Surgery, the Second Affiliated Hospital of Inner Mongolia Medical University from December 2010 to December 2014 (including 2 years of fol ow-up) were selected and conducted total hip arthroplasty using biological type total hip prosthesis. During 2 years of fol ow-up, hip activity (total activity, flexion and extension, adduction, abduction, internal rotation, external rotation), hip Harris score, pain visual analog scale score, quality of life of patients were observed, counted and comparatively analyzed before replacement and in the final fol ow-up. RESULTS AND CONCLUSION:The hip joint activity and other various indexes of patients in the final fol ow-up significantly recovered compared with before treatment (P<0.05). Before treatment, the hip joint pain of patients was severe, the function and the quality of life were poor, however, in the final fol ow-up, the pain of patients was obviously relieved, hip function effectively recovered and quality of life improved significantly, the differences were statistical y significant (P<0.05). These results suggest that the application of total hip arthroplasty by using biological type total hip prosthesis on patients with ankytosing spondylitis-associated hip joint lesion can effectively restore physiological and anatomical structure of the hip joint, restore the function and activity of hip joint, relieve pain, and improve the quality of life.
