Abstract:

BACKGROUND: The etiologies of total hip replacement are complex, such as femoral neck fracture, avascular necrosis of the femoral head, primary osteoarthritis, congenital hip dysplasia, rheumatoid arthritis, ankylosing spondylitis, traumatic arthritis and infectious arthritis. Due to different causes and epidemiological characteristics of these diseases, they occupy different percentages in total hip replacement.
OBJECTIVE: To analyze the etiological composition of patients in Hefei area undergoing total hip replacement and the distribution in ages and genders, in a broader attempt to improve the early screening and prevention of hip diseases and susceptible factors.
METHODS: A retrospective study was performed in 3 056 patients receiving total hip replacement in five hospitals in Hefei area from January 2008 to December 2013. These patients were divided into 11 groups according to discharge diagnosis, and the constituent ratio of ages and genders was analyzed.
RESULTS AND CONCLUSION: Among the involved 3 056 patients, 1 763 patients had hip fracture (56.78%), 545 avascular necrosis of femoral head (17.55%), 461 primary osteoarthritis (14.85%), 196 developmental dysplasia of hip (6.31%), 35 rheumatoid arthritis (1.13%), 10 ankylosing spondylitis (0.32%), 26 traumatic arthritis (0.84%),12 infective arthritis (0.39%), 4 tumor of hip (0.13%), 3 fibrous dysplasia of bone (0.097%), and 1 Kaschin Beck disease (0.032%). The proportion of patients over 50 years old was obviously higher than that of the patients under age of 50 years (including 50 years; χ2= 12.7, P < 0.05). The proportion of female patients was higher than that of male patients (χ2=61.07, P < 0.05). The results showed that the etiologies of the patients receiving total hip replacement in five hospitals in Hefei area are complex, the major causes include hip fracture, avascular necrosis of femoral head and primary osteoarthritis, the main patients are over 50 years old, and the proportions of female patients is higher than that of the male patients.
