Treatment of Spondylolisthesis in Isthmic Spondylolisthesis, Meyerding Grade I or II
Clinical Scenario
This protocol addresses patients with isthmic spondylolisthesis classified at Meyerding Grade I or II. Isthmic spondylolisthesis arises from a defect or fracture of the pars interarticularis — frequently progressing from pre-existing spondylolysis — and is often driven by repetitive mechanical stress. At these low grades, conservative management is the standard approach, particularly for patients who are asymptomatic or presenting with mild to moderate symptoms without significant neurological deficits.
Initial Management Approach
Management begins with short-term rest and activity modification — including avoidance of lumbar hyperextension — alongside analgesic or anti-inflammatory therapy; spinal bracing may also be incorporated depending on presentation.
The complete sequenced regimen, including specific agent selection and escalation criteria, is available in the full protocol.
Treatment Goals
Low back pain relief
No further vertebral slippage

- Isthmic spondylolisthesis is primarily associated with a defect or fracture in the pars interarticularis, often caused by repetitive mechanical stress, and frequently progresses from a pre-existing spondylolysis.
- Conservative treatment is typically recommended for patients with low-grade spondylolisthesis (grades I and II), especially those who are asymptomatic or have mild to moderate symptoms without significant neurological deficits.
- For patients with isthmic spondylolisthesis, conservative treatment for three to six months has demonstrated good outcomes, managing most unilateral pars lesions and approximately 50% of bilateral lesions.
- The most generally accepted protocol begins with one to two days of rest and activity modification, followed by administering analgesics or anti-inflammatory medication.
- The first-line treatment for lower back pain associated with spondylolisthesis includes nonsteroidal anti-inflammatory drugs (NSAIDs) and/or analgesics.
- Bracing is usually recommended for acute spondylolysis or early-stage spondylolisthesis in young athletes, especially in sports that involve repeated lumbar hyperextension, such as gymnastics or football.
- The findings demonstrated reduced pain and no evidence of further vertebral slippage.
