Diagnosis and Imaging
The Clinical Evaluation Process For Children
The journey toward a successful recovery begins with a meticulously structured diagnostic evaluation. Because children's bones are mostly cartilage and still developing, a standard physical exam requires specialized knowledge of pediatric growth markers. When you visit a specialist at Liv Hospital, the process starts with a detailed medical history focusing on birth position, developmental milestones, and the timing of any injuries. The goal of this evaluation is to provide objective evidence of joint health and to determine if a structural intervention is the most appropriate next step for the child's growth.
Physical Examination And Gait Analysis

The first line of diagnosis involves a hands on assessment of the child's flexibility, strength, and range of motion.
- Observing the child's "gait" or the way they walk to identify limps or imbalances.
- Testing for joint stability and ligament tension.
- Measuring limb length and spinal alignment during bending tests.
These clinical signs provide the surgeon with an initial map. If the child is favoring one side or has limited motion, it is a strong indicator that the skeletal integrity is compromised, justifying further investigation with high tech imaging.
Standard Low Dose X-Ray Protocols

X-rays remain the foundational imaging tool for evaluating fractures and bone alignment.
- Identifying the type of fracture and its proximity to the growth plate.
- Visualizing the degree of spinal curvature in scoliosis cases.
- Assessing the depth of the hip socket in infants.
At Liv Hospital, we utilize "low dose" digital X-ray technology to ensure the highest resolution images with minimal radiation exposure, providing a clear view of the skeletal framework while protecting the child's long term health.
Advanced EOS 3D Imaging Technology
Liv Hospital utilizes the cutting edge EOS imaging system, which provides life sized, 3D reconstructions of the child in a standing position.
- It allows for the precise measurement of spinal and limb rotation.
- It uses significantly less radiation than traditional CT scans.
- It provides a complete visual of how the skeletal system handles the child's weight.
This high tech imaging is a hallmark of the precision care at our facility, ensuring that every part of a scoliosis or limb lengthening plan is based on anatomical accuracy.
Magnetic Resonance Imaging (MRI) For Soft Tissues
While X-rays show the bone, an MRI is essential for viewing the "hidden" soft tissues that are often damaged in sports injuries.
- Detecting tears in the meniscus, ACL, or rotator cuff.
- Visualizing inflammation in the joint lining or surrounding tendons.
- Identifying early stages of bone infection or tumors.
An MRI provides the clinical team with a visual blueprint of the internal environment, ensuring that any subsequent surgery or therapy addresses the soft tissue health as well as the bone structure.
Diagnostic Ultrasound For Infant Hips
Ultrasound is an invaluable tool for visualizing the Pediatric Hip, especially in newborns.
- It allows clinicians to see the cartilage of the hip ball and socket before it turns to bone.
- It is the gold standard for diagnosing Developmental Dysplasia of the Hip (DDH).
- It is a completely radiation free and painless procedure.
At Liv Hospital, we use ultrasound to screen high risk infants, ensuring that structural issues are caught and treated before the child begins to walk.

Computed Tomography (CT) For Complex Bone Mapping
In complex clinical cases, especially those involving intricate fractures or planning for reconstructive surgery, a CT scan may be recommended.
- Providing a three dimensional reconstruction of the bone's internal architecture.
- Precise mapping for the placement of surgical screws or plates.
- Helping the surgeon plan for "patient specific" treatments.
Using high tech CT protocols ensures that the surgical team has a complete map of the child's skeletal frame, ensuring that every part of the repair is positioned with accuracy.
Laboratory Tests And Metabolic Screening
Because some orthopedic issues are related to internal chemistry, blood work is often part of our evaluation.
- Checking levels of Calcium, Vitamin D, and alkaline phosphatase.
- Screening for inflammatory markers to rule out childhood arthritis.
- Assessing for signs of systemic infection that could impact bone health.
Treating the bone without addressing the body's internal chemistry is only half the battle. A full evaluation ensures that your child's system is optimized to support the biological repair process.
Assessing The Visual Future Of The Joint
During the evaluation, the specialist considers the long term visual and physical outcome for the patient.
- Predicting how an injury today will affect the limb's length at age eighteen.
- Assessing the risk of future joint wear based on current alignment.
- Choosing the most bio compatible materials for any necessary implants.
By taking a comprehensive view of the child's future mobility, we ensure that the diagnosis is not just about the current pain, but about preserving the ability to move for a lifetime.
Reaching A Definitive Management Plan
The end goal of the diagnostic phase is to reach a clear and confident management plan. Once all tests are completed—physical exam, imaging, and labs—your specialist will sit down with you and your child to review the findings. At Liv Hospital, we believe in a transparent diagnostic process where the family is an active participant. Replacing uncertainty with a clear, data driven plan is the first step toward a future of strength.
Frequently Asked Questions
Why is radiation exposure a concern for children
Children's cells are dividing rapidly, making them more sensitive to radiation than adults. Also, they have a longer life expectancy, giving more time for any potential radiation induced issues to develop. We use the ALARA principle (As Low As Reasonably Achievable) to minimize risk.
What is bone age
Bone age is a way to measure a child's physical maturity. We take an X ray of the left hand and wrist and compare the appearance of the growth plates to a standard atlas. This tells us how much growth remains, which is crucial for timing surgeries like leg lengthening or scoliosis correction.
Why does my toddler need an ultrasound instead of an X ray for hips
Until about 4 to 6 months of age, the head of the femur (hip ball) is made of cartilage. Cartilage is invisible on X ray. Ultrasound waves can see through soft tissue and cartilage, allowing us to see the hip joint clearly before it turns to bone.
What is a gait lab
A gait lab is a high tech room with cameras and sensors on the floor. We put reflective markers on the child's legs. As they walk, a computer creates a stick figure model of their movement. It tells us exactly how their joints and muscles are working, which helps plan complex surgeries.
Can an MRI show a growth plate fracture
Yes, MRI is excellent for showing growth plate injuries that might be invisible on X ray. It can show swelling within the growth plate itself or subtle fractures that haven't displaced the bone but still need treatment to prevent growth arrest.
