Abstract

Background

Previous studies on corticosteroid use and idiopathic osteonecrosis of the femoral head (ONF) have been conducted involving patients with systemic lupus erythematosus and renal transplantation, among other disorders, which make it possible only to compare high- and low-dose corticosteroids. The main objective here was to estimate the impact of oral corticosteroid use for idiopathic ONF compared to nonuse of corticosteroids. In addition, we investigated the relations between underlying medical conditions and idiopathic ONF.

Methods

A nationwide multicenter case-control study was conducted in Japan. Cases were defined as patients who visited the cooperative orthopedic department after January 2002 and received a diagnosis of idiopathic ONF after the visit. For each case, up to five matched controls were selected from among patients without idiopathic ONF who consulted the same orthopedic department after the visit of the identified case. The matching conditions were sex, age (5-year age groups), and ethnicity. The subjects’ demographic and anthropometric data and histories of medications, diseases, alcohol consumption, and smoking were collected by a structured self-administered questionnaire. A conditional logistic regression model was used to obtain the odds ratios (ORs) and 95% confidence intervals (CIs).

Results

A total of 73 cases and 250 matched controls completed the questionnaire. After adjustment for the potential confounders, the multivariate OR of oral corticosteroid use compared to nonuse was 20.3 (95% CI 6.73–61.5). Furthermore, a positive association of liver disease with idiopathic ONF was observed with marginal significance (multivariate OR 3.53, 95% CI 0.88–14.1) regardless of oral corticosteroid use, alcohol consumption, and smoking.

Conclusions

The current findings first revealed the impact of oral corticosteroid use for idiopathic ONF compared to nonuse. However, because the regimen of corticosteroid therapy (dose and duration) could not be assessed, further study is required. An independent role of liver disease was also suggested.

      There is no consensus on the common pathophysiologic mechanism of osteonecrosis development. The etiology of ONFH is multifactorial, but alcohol abuse [5], high-dose corticosteroid use [6], and autoimmune diseases [7] are the 3 most commonly accepted associated risk factors. Up to now, however, there are a substantial number of patients who have no identifiable risk factors, and they were diagnosed with idiopathic ONFH [1,20].

      However, epidemiological surveys in Japan reported that the occurrence of ONFH was significantly associated with both current and cumulative alcohol intake [2,3]. The epidemiological survey revealed that adjusted odds ratio of the patients with ≧3000 drink-years (weekly ethanol consumption × years) was 3.86 compared with never-drinkers [11]. ONFH due to heavy alcohol intake is likely caused by lipid metabolism disorders and increased blood cortisol [12,13].
