Prevalence of coxarthrosis
Clinical Orthopaedics and Related Research
|December 1, 1984
Summary
Prevalence of primary coxarthrosis (hip osteoarthritis) remained stable over 20 years. A third of patients had undiagnosed hip osteoarthritis, with specific types more common in men.
Area of Science:
- Orthopedics
- Radiology
- Epidemiology
Background:
- Primary coxarthrosis, or hip osteoarthritis, is a common degenerative joint disease.
- Previous studies have established baseline prevalence and characteristics of hip osteoarthritis.
Purpose of the Study:
- To compare the prevalence, type, and severity of primary coxarthrosis over a 20-year period.
- To analyze demographic and diagnostic differences in hip osteoarthritis cases.
Main Methods:
- Retrospective analysis of 4027 double-contrast colon roentgenograms, examining hip joints for coxarthrosis.
- Classification of hip joints based on presence, type, and severity of primary coxarthrosis.
- Comparison of current data with a similar study conducted over 20 years prior.
Main Results:
- Hip joint coxarthrosis prevalence, sex ratio, and distribution of bilateral/unilateral cases remained unchanged over two decades.
- Approximately one-third of patients had undiagnosed hip osteoarthritis; mixed and medial types were more prevalent in men.
- Lateral coxarthrosis was more common in patients treated with total hip arthroplasty (THA), with women over-represented in THA cases despite similar coxarthrosis severity.
Conclusions:
- The epidemiological characteristics of primary hip osteoarthritis have not significantly changed over the past 20 years.
- A substantial proportion of hip osteoarthritis cases remain undiagnosed, highlighting potential for earlier detection.
- Total hip arthroplasty is frequently utilized for hip osteoarthritis, with specific patterns observed in relation to coxarthrosis type and patient demographics.
