Diagnosis and Imaging
The Clinical Evaluation Process For Hip Pain
The journey toward a successful hip replacement begins with a meticulously structured diagnostic evaluation. Because hip pain can be referred from the lower spine or caused by muscular issues, a physical exam alone is rarely sufficient. When you visit a specialist at Liv Hospital, the process starts with a detailed medical history where the clinician asks about the onset of your pain and how it affects your walking gait. The goal of this evaluation is to provide objective evidence of joint damage and to determine if a structural intervention is the most appropriate next step for your physical vitality.
Physical Examination And Mobility Testing
The first line of diagnosis involves a hands on assessment of your hip’s range of motion and stability.
- Assessing your “gait” to see if you are favoring one side.
- Testing for muscle weakness in the gluteal and thigh regions.
- Measuring limb length to check for discrepancies caused by bone loss.
These clinical signs provide the surgeon with a map of the joint’s functional failure. If the joint catches or causes sharp pain during specific maneuvers, it is a strong indicator that the internal cartilage is compromised and a hip replacement should be considered.
Standard X-Ray Protocols For Joint Assessment
X-rays are the foundational imaging tool for evaluating the need for a hip replacement. They provide a clear view of the relationship between the ball and the socket.
- Identifying “bone on bone” contact where the joint space has disappeared.
- Visualizing bone spurs (osteophytes) that physically limit movement.
- Assessing the quality and density of the surrounding bone tissue.
At Liv Hospital, we use digital X-ray technology to ensure the highest resolution images with minimal radiation exposure, providing a clear view of the skeletal framework for planning your surgery.
Magnetic Resonance Imaging (MRI) For Soft Tissue
While X-rays show the bone, an MRI is used to see the “hidden” soft tissues. This is especially important for identifying early stages of tissue failure.
- Detecting labral tears, which are rips in the cartilage ring of the socket.
- Identifying early stages of avascular necrosis before the bone collapses.
- Visualizing inflammation in the joint lining or surrounding tendons.
An MRI provides the clinical team with a visual blueprint of the internal environment, ensuring that any subsequent surgery addresses the surrounding soft tissue health as well as the bone.
Computed Tomography (CT) Scans For 3D Mapping
In complex cases, especially those involving dysplasia or previous orthopedic surgeries, a CT scan may be recommended.
- Providing a three dimensional reconstruction of the hip anatomy.
- Precise mapping for the placement of components during a total hip replacement.
This high tech imaging is a hallmark of the precision care at Liv Hospital, ensuring that every prosthetic part is positioned with microscopic accuracy to match your unique anatomy, which is essential for joint longevity.
Laboratory Tests And Systemic Screening
Because we view the joint in the context of the whole body, blood work is often part of our evaluation.
- Inflammatory markers to check for systemic conditions like rheumatoid arthritis.
- Screening for any active infections that could compromise a surgical outcome.
- Assessing nutritional levels, such as Vitamin D, which are vital for bone healing.
Treating the underlying health of the patient is often just as important as the surgery itself. If your body is in a state of high systemic stress, we may work to stabilize your response before proceeding with a hip operation replacement.
Diagnostic Joint Injections
In some clinical cases, a diagnostic injection is used to confirm that the pain is definitely originating from within the hip joint.
- A small amount of numbing medicine is injected into the joint under ultrasound guidance.
- If the patient experiences immediate relief, the hip is confirmed as the primary source.
- This helps rule out pain coming from the lower back or the pelvic muscles.
This functional test ensures that a hip replacement will actually solve the patient’s problem, preventing unnecessary procedures and focusing care where it is most needed.
Bone Density Scans (DEXA)
Before a hip replacement, it is vital to know the strength of the foundation. A DEXA scan measures bone mineral density.
- Identifying osteoporosis or osteopenia that might affect implant stability.
- Determining if the implant should be “cemented” or “press fit” into the bone.
- Ensuring the bone is strong enough to support the new joint for decades.
At Liv Hospital, we prioritize long term success. If bone density is low, we may initiate medical treatment to strengthen the bone before or during your surgical journey.
Assessing The Visual Future Of The Joint
During the evaluation, the surgeon considers the long-term visual and physical outcome for the patient.
- Minimizing the risk of future dislocations through precise component angles.
- Ensuring the limb lengths are perfectly balanced after the procedure.
- Choosing the most bio compatible materials for your specific profile.
By taking a comprehensive view of your future mobility, we ensure that the diagnosis is not just about the current pain, but about preserving your ability to walk and move for thirty years or more.
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 to review the findings. At Liv Hospital, we believe in a transparent diagnostic process. If you are struggling with unresolved hip pain, reach out to us today for a comprehensive evaluation to secure your physical and visual future. Replacing uncertainty with a clear, data driven plan is the first step toward a life of comfort.

FREQUENTLY ASKED QUESTIONS
Does an X-ray hurt?
No, X-rays are painless. The scan is sensation-free, but you may have to twist your leg into certain positions to get the right angle, which can be uncomfortable if your hip is stiff.
Why do I need a CT scan if I have X-rays?
X-rays are 2D pictures. A CT scan gives a 3D view. This form of imaging is critical for measuring the rotation and depth of your socket, allowing for much more precise implant positioning, especially in robotic surgery.
Can I have an MRI if I have a pacemaker?
It depends on the device. Many modern pacemakers are MRI-safe, but older ones are not. You must tell your doctor and the MRI technician about any implants you have.
How do they measure leg length?
Doctors measure leg length on X-rays by drawing lines across the pelvis and comparing the position of the thigh bones. They also use tape measures during the physical exam. Restoring equal leg length is a key goal of surgery.
Will I need blood tests?
Yes. Before surgery, you will have blood tests to check your hemoglobin (red blood cells), kidney function, and clotting ability. This ensures you are healthy enough for anesthesia and the procedure.
