X-Rays in Chiropractic Care | Pura Vida Chiropractic San Antonio
Learn why chiropractors take X-rays, what spinal X-rays reveal, and how Dr. Dan Foss uses imaging at Pura Vida Chiropractic in San Antonio, TX.

Chiropractors take X-rays to obtain detailed information about the bone structure and alignment of the spine and other joints. X-rays are an important tool that helps chiropractors diagnose musculoskeletal problems and determine the best treatment plan for each patient.
X-rays can provide information about spinal alignment, spinal curvature, the presence of fractures, joint degeneration, and other bony abnormalities. This information helps chiropractors identify the underlying cause of a patient's pain or dysfunction and develop a personalized treatment plan.
Additionally, X-rays can be useful for monitoring the progress of chiropractic treatment over time and evaluating whether chiropractic adjustments are improving spinal alignment and function.
It is important to note that while X-rays are a valuable tool, not everyone seeking chiropractic care needs them. Dr. Foss evaluates the need for X-rays based on each patient's clinical history, symptoms, and physical examination.
When Does Dr. Foss Take X-Rays?
Dr. Dan Foss at Pura Vida Chiropractic uses X-rays selectively and responsibly. Imaging is typically recommended in the following situations:
- Recent trauma — If you've been in a car accident, a significant fall, or other trauma, X-rays help rule out fractures or dislocations before treatment begins
- Severe or chronic pain — When pain is intense, persistent, or has lasted several months without an identified cause
- Neurological symptoms — Numbness, tingling, or weakness in the arms or legs may indicate nerve compression that requires imaging to confirm
- History of osteoporosis or cancer — Patients with these conditions have a higher risk of bony abnormalities that should be ruled out before treatment
- Spinal curvature assessment — For diagnosis and monitoring of scoliosis, lordosis, or kyphosis
- Patients over 60 with new spinal pain — To evaluate joint degeneration and age-related changes
What Spinal X-Rays Reveal
Alignment and Curvature
The normal spine has specific curves when viewed from the side — a forward curve in the neck (cervical lordosis), a backward curve in the mid-back (thoracic kyphosis), and a forward curve in the lower back (lumbar lordosis). Deviations from these normal curves can relate to pain and dysfunction. Dr. Foss is experienced in measuring and analyzing these curves to determine whether they are a contributing factor to a patient's symptoms.
Disc and Joint Degeneration
X-rays show the space between vertebrae, which corresponds to the thickness of the intervertebral disc. A reduced space indicates disc degeneration. X-rays also reveal osteophyte (bone spur) formation and joint changes associated with arthritis, helping Dr. Foss tailor treatment accordingly.
Subluxations and Misalignment
Vertebral subluxations — misalignments of the vertebrae that interfere with nerve function — are often visible on X-rays. Identifying these misalignments precisely allows Dr. Foss to direct adjustments more effectively and track improvement over time.
Congenital Anomalies
Some people are born with anatomical variations in the spine that are relevant to chiropractic treatment. X-rays reveal these variants and help Dr. Foss adapt his approach to maximize safety and effectiveness.
Safety and Radiation Exposure
At Pura Vida Chiropractic, we use modern digital X-ray equipment that produces significantly less radiation than conventional film-based systems. Spinal X-rays expose the patient to a radiation dose comparable to several hours of air travel or several days of natural background radiation.
Pregnant women generally avoid X-rays unless absolutely necessary. Dr. Foss always discusses benefits and risks with each patient before ordering any imaging.
How Dr. Foss Uses X-Rays in Your Evaluation
X-rays are only one part of the comprehensive evaluation Dr. Foss performs. They are always interpreted in the context of the patient's complete clinical history, physical and neurological examination findings, current symptoms, and treatment goals. This holistic approach ensures that X-rays provide genuinely useful information rather than being taken routinely without clinical justification.
With more than 23 years of experience, Dr. Foss has extensive training in interpreting spinal X-rays in the context of chiropractic analysis. His advanced training in Sacro-Occipital Technique (SOT) and postural analysis allows him to extract valuable diagnostic information from imaging to design a more precise and effective treatment plan.
Frequently Asked Questions
Will I need X-rays at my first visit? Not necessarily. Dr. Foss will determine during your examination whether X-rays are clinically indicated for your specific situation. Many patients are treated effectively without imaging.
Can I bring previous X-rays from another provider? Yes, and you're encouraged to do so. Prior imaging provides valuable information about your spinal history and can reduce the need for new radiation exposure.
How long does it take to get results? With our digital X-ray system, images are available immediately. Dr. Foss will review them with you during your visit and explain what they show in terms you can understand.
