Abstract

BACKGROUND:

There are relationships between the causes, gender and age of patients with total hip replacement. The common causes are hip osteoarthritis, aged femoral neck fracture, aseptic necrosis of femoral head and hip local lesion in systemic disease.

OBJECTIVE:

To study the etiological composition of patients with total hip replacement for the first time and its distribution in ages and genders.

METHODS:

A retrospective analysis was performed in 974 patients received total hip replacement for the first time in Affiliated Nanfang Hospital of Southern Medical University from January 2003 to December 2010. All the patients were Guangzhou residents. The patients were divided into 9 groups according to discharge diagnosis, and the composition of ages and genders was analyzed.

RESULTS AND CONCLUSION:

Seventy patients were of primary osteoarthritis (7.19%), 64 of congenital hip dysplasia (6.57%), 78 of ankylosing spondylitis (8.01%), 518 of avascular necrosis of femoral head (53.18%), 220 of femoral neck fracture (22.59%), 10 of tumor of hip (1.03%), 8 of rheumatoid arthritis (0.82%), 4 of infective arthritis (0.42%), and 2 patients were of hematological disease (0.21%). The proportion of patients over 50 years old was obviously higher than that of the patients under age 50 and age 50 (x2= 104, P < 0.05). The proportion of female patients was higher than that of the male patients, but the difference was not significant (x2= 1.73, P > 0.05). The results showed that the causes of the patients received total hip replacement for the first time in Affiliated Nanfang Hospital of Southern Medical University in Guangzhou were complex, the major causes were avascular necrosis of femoral head and femoral neck fracture, the main patients were over 50 years old, and the proportions of female and male patients were similar.
