Severity of 7mm Anterolisthesis
The severity of 7mm anterolisthesis can be understood by analyzing the provided studies.
- A study by 1 categorized spondylolisthesis into three groups: severe (displacement of 3.5 mm or more), moderate (displacement of 2.0-3.4 mm), and mild (less than 2.0 mm displacement).
- Another study by 2 defined listhesis as present when the subluxation was 3 mm or more.
- A study by 3 found that cervical degenerative spondylolisthesis with 2-7 mm of displacement was relatively common in the elderly and seemed to be stable during 2-8 years of follow-up.
Comparison with Other Studies
- A study by 4 reported a case of grade 4 anterolisthesis, which is a more severe condition than 7mm anterolisthesis.
- Another study by 5 focused on retrolisthesis, which is a different condition than anterolisthesis, but also related to spinal instability.
Key Findings
- The severity of 7mm anterolisthesis can be considered moderate to severe based on the categorization by 1.
- The study by 3 suggests that cervical degenerative spondylolisthesis with 2-7 mm of displacement is relatively stable and may not progress over time.
- However, the severity of anterolisthesis can vary depending on individual factors, such as age, spinal level, and presence of other degenerative changes.
Spinal Level and Age
- The study by 2 found that the prevalence of anterolisthesis increased with age and varied by spinal level.
- The study by 3 found that cervical degenerative spondylolisthesis was more common in older adults and seemed to be stable over time.
Clinical Implications
- The study by 1 found that patients with severe spondylolisthesis had a high incidence of degenerative spondylolisthesis at C3/4 or C4/5 and significantly greater cervical mobility than those with mild spondylolisthesis.
- The study by 5 found that stand-alone anterior lumbar interbody fusion was associated with radiographic and clinical improvement in patients with symptomatic L5-S1 retrolisthesis.
