From the Guidelines
For patients presenting with straightened lumbar lordosis and a lumbar levocurvature, initial management should focus on conservative approaches such as physical therapy and pain management, rather than immediate imaging, unless red flags or specific clinical scenarios as outlined in Variant 3 of the ACR Appropriateness Criteria are present 1.
Clinical Considerations
When evaluating a patient with straightened lumbar lordosis and a lumbar levocurvature, it's essential to consider the patient's overall clinical presentation, including the presence of any red flags such as recent trauma, fever, or unexplained weight loss. The American College of Radiology (ACR) provides guidelines for the appropriate use of imaging in patients with low back pain, which can help guide decision-making in these cases 1.
Imaging Recommendations
According to the ACR Appropriateness Criteria, imaging is usually not appropriate for the initial evaluation of patients with acute low back pain without red flags or prior management (Variant 1) 1. Similarly, for patients with subacute or chronic low back pain, imaging may not be necessary initially unless there are specific indications such as suspected cauda equina syndrome (CES), history of prior lumbar surgery, or certain risk factors like osteoporosis or chronic steroid use (Variants 4,5, and 6) 1.
Treatment Approach
The treatment approach for straightened lumbar lordosis with a lumbar levocurvature should prioritize conservative management, including:
- Physical therapy to address muscle imbalances, improve posture, and enhance spinal flexibility.
- Pain management using over-the-counter anti-inflammatories or, in some cases, prescription medications under the guidance of a healthcare provider.
- Lifestyle modifications such as regular exercise, maintaining a healthy weight, and improving sleep habits.
Special Considerations
In cases where conservative management fails to provide adequate relief or if specific clinical scenarios are present (e.g., suspicion of cancer, infection, or immunosuppression), further evaluation with imaging, such as MRI, may be warranted (Variant 7) 1. It's crucial to tailor the management plan to the individual patient's needs and clinical presentation, considering factors such as the presence of radiculopathy, prior surgical history, and the presence of red flags.
From the Research
Straightened Lumbar Lordosis with a Lumbar Levocurvature
- A straightened lumbar lordosis refers to a reduction in the normal inward curve of the lower back [ 2 ].
- Lumbar levocurvature, on the other hand, refers to an abnormal curvature of the lumbar spine to the left [ 3 ].
- The optimal lordotic range remains unknown and may be related to a variety of individual factors such as weight, activity, muscular strength, and flexibility of the spine and lower extremities [ 2 ].
Factors Associated with Lumbar Lordosis
- Age, gender, body mass index, ethnicity, and sport may affect the lordosis angle, making it difficult to determine uniform normal values [ 2 ].
- Normal lordosis should be determined based on the specific characteristics of each individual [ 2 ].
- There is evidence that the lumbar lordosis angle is positively and significantly associated with spondylolysis and isthmic spondylolisthesis [ 2 ].
Relationship between Lumbar Lordosis and Low Back Pain
- The relationship between lumbar lordotic curvature and low back pain has immense clinical significance [ 4 ].
- A meta-analysis demonstrates a strong relationship between low back pain and decreased lumbar lordosis, especially when compared with age-matched healthy controls [ 4 ].
- Among specific diseases, low back pain by disc herniation or degeneration was shown to be substantially associated with the loss of lumbar lordosis [ 4 ].
Measurement of Lumbar Lordosis
- The optimal position for radiologic measurement of lordosis is standing with arms supported while shoulders are flexed at a 30° angle [ 2 ].
- Non-radiological surface measurement of the lumbar lordosis curvature in the standing position can be used to define normal values and investigate its association with age, sex, and body mass index [ 5 ].
