Abstract

BACKGROUND CONTEXT:

Degenerative changes in the lumbar spine may result in a loss of spinal stability and subluxation of one vertebra relative to another. Cadaveric studies and clinical case series have suggested that listhesis may be much more common in African Americans than in whites.

PURPOSE:

To determine the prevalence of lumbar spine listhesis (anterolisthesis and retrolisthesis) among African American women aged 65 years and older and the relationship of listhesis to low back pain, physical function and quality of life.

STUDY DESIGN/SETTING:

Cross-sectional study.

PATIENT SAMPLE:

A total of 481 African American women aged 65 years and older who were enrolled in the Study of Osteoporotic Fractures. These women were recruited from population-based listings in Baltimore, MD, Minneapolis, MN, Pittsburgh, PA, and Portland, OR.

OUTCOME MEASURES:

Not applicable.

METHODS:

Lateral radiographs of the lumbar spine were digitized, and listhesis (anterolisthesis and retrolisthesis) was assessed at spinal levels L3-L4, L4-L5 and L5-S1. Usable data were obtained for 470 women. Listhesis was defined as present when the subluxation (antero or retro) was 3 mm or more.

RESULTS:

The overall prevalence of anterolisthesis was 58.3% and varied by spinal level (13.2% at L3-L4, 36.5% at L4-L5 and 29.6% at L5-S1). The prevalence increased with age but was lower among oophorectomized women and those currently on estrogen replacement therapy. Anterolisthesis was not associated (p>.05) with disc height nor was it related to back function. Retrolisthesis occurred in 4% of women and was associated with decreased disc height and an increased prevalence of spinal problems and walking problems.

CONCLUSIONS:

The prevalence of anterolisthesis among older African American women living in the community was two to three times greater than that found in white women of a similar age. This condition was not related to an increased frequency of back problems nor did it adversely affect general physical function. Retrolisthesis was relatively rare but was associated with decreased back function.
