Uneven Hips: Why Is One Hip Higher Than the Other?

Uneven hips are sometimes called a lateral pelvic tilt. It means one side of your pelvis sits higher, or further forward, than the other. The cause can be a difference in leg length, a muscle imbalance, a curve in the spine, or a mix of all three. Your pelvis links your spine to your legs. So a tilt here often causes pain or stiffness in places you would not expect.

Key points

  • Uneven hips are common. They can be structural (bone-related) or functional (related to muscles and habits).
  • Pain from a pelvic tilt often shows up in the lower back, the knee or even the other hip, not where the tilt is.
  • Scans taken lying down relax the muscles and can hide the tilt. A standing, weight-bearing image shows how your pelvis really sits when you are upright.
  • Knowing whether the cause is structural or functional changes the approach completely.
  • An EOS whole-body standing scan captures your alignment from head to feet in a single image with about 90% less radiation than a standard X-ray.

How can you tell if your hips are uneven?

Many people first notice it when their clothes fit oddly, a waistband sits at an angle, or one hip sticks out more than the other. But the signs often go further than what you can see in a mirror.

One shoulder or hip looks higher

When you stand in front of a mirror, one side of your pelvis or one shoulder looks clearly higher than the other.

Lower back pain on one side

A lateral pelvic tilt forces your spine to curve to make up for it. This often brings an ache in the lower back on one side.

Knee or leg pain

When the pelvis tilts, one leg in effect works harder. This can lead to knee strain, IT band tightness or hip bursitis.

Uneven shoe wear or walk

You may wear out one shoe faster, or people may say your walk looks uneven.


What causes uneven hips?

Uneven hips fall into two broad groups: structural and functional. A structural cause means there is a real difference in bone length or joint shape. A functional cause means the bones are normal, but muscles, habits or compensation patterns pull the pelvis out of line.

Leg-length difference

Even a small difference in leg length tilts the pelvis when you stand. This may be in the bone itself, or come from a joint problem such as hip arthritis.

Scoliosis

A sideways curve in the spine can shift the pelvis. It can also work the other way round: a pelvic tilt creates a curve in the spine to make up for it.

Muscle imbalance

Tight hip flexors on one side, or a weak gluteal muscle, can pull the pelvis into a tilt with no bony cause at all.

Posture habits

Years of standing on one leg, sitting cross-legged or carrying weight on one side can train the pelvis into an off-centre position.

Often the cause is a mix. A small structural difference in leg length may be made worse by tight muscles and a long-standing posture habit. That is why imaging the whole body together, while you stand, gives a much clearer answer than looking at the hip alone.


Why does a pelvic tilt cause pain in other places?

Your body is a connected chain from your feet to your head. When the pelvis tilts, everything above and below it has to adjust. The spine curves to keep your head level. One knee takes more load. Muscles on one side work harder than on the other.

This adjustment is what catches people out. You might have your knee scanned because it aches, and the scan looks normal. Or your lower back is checked on its own and nothing obvious shows up. The real cause, a tilted pelvis, can only be seen when you look at the full chain in a standing position.

Lying-down imaging, whether X-ray, CT or MRI, relaxes the muscles and lets gravity flatten out the tilt. The misalignment that causes your symptoms when you are on your feet can simply vanish on the scan table. That is not a fault with those scans. They are made for other purposes. It just means they can miss alignment problems that only show up under load.


How is a pelvic tilt checked with a standing scan?

An EOS scan captures your skeleton from head to feet in a single upright image while you stand naturally. Because you are bearing your own weight, your pelvis, spine and legs are shown exactly as they work in daily life. The scan uses about 90% less radiation than a standard X-ray, around ten times less.

From this one image, a specialist radiographer can see whether one hip really sits higher, whether a difference in leg length is playing a part, and how much your spine is curving to make up for it. It removes the guesswork of piecing together separate scans of different body parts.

When MRI is the better choice: EOS shows bones, joints and alignment. If your clinician suspects a soft-tissue problem such as a labral tear, a disc problem or nerve irritation, MRI is usually the better tool. The two types of imaging answer different questions and often work well together.


What helps with uneven hips?

The right approach depends entirely on the cause. That is why an accurate diagnosis comes first. Without knowing whether the tilt is structural, functional or both, any exercise plan or treatment is based on guesswork.

For a functional tilt caused by muscle imbalance, targeted stretching and strengthening, guided by a physiotherapist, often works well. For a structural difference in leg length, a heel raise or orthotics may be considered. In some cases, further specialist input is needed.

ScanAlign is a diagnostic imaging clinic. We do not provide treatment. We give you and your clinician the detailed alignment information needed to choose the right next step. If you do not already have a specialist, we can point you in the right direction after your scan.

So before you start a treatment, or change the one you are on, it is worth getting a detailed diagnosis. Knowing whether the cause sits in your pelvis, your legs or your spine changes what will really help.


Common questions about uneven hips

If the cause is purely functional, such as tight muscles on one side, targeted exercises and stretches can make a real difference. But if there is a structural cause such as a difference in leg length, exercises alone will not change the bones. That is why finding the cause first matters so much.

Stand in front of a mirror in your underwear and place your hands on the top of your hip bones (the iliac crests). If one hand sits clearly higher, your pelvis may be tilted. This is only a rough guide. It cannot tell you whether the cause is in the hip, the leg or the spine.

Yes, they mean the same thing. "Lateral pelvic tilt" is the medical term for a pelvis that is higher on one side when seen from the front. "Uneven hips" or "one hip higher" is how most people describe it in everyday language.

Yes. When the pelvis tilts, one leg carries more weight and the angle of the thigh bone into the knee changes. Over time, this extra stress can lead to knee pain, IT band tightness or even early wear of the joint. You can read more about how alignment affects the knee on our knee alignment page.

Most X-rays are taken lying down. In that position, gravity and relaxed muscles can flatten the tilt, so the pelvis looks more level than it really is. A standing X-ray or EOS scan captures the pelvis under your full body weight, the way it really sits when you walk and stand.

No. ScanAlign is a private, self-pay clinic and you can refer yourself. We suggest starting with a free video consultation so we can check that a standing scan is the right next step for your symptoms.

Yes. EOS uses about 90% less radiation than a standard X-ray, around ten times less. You can find more about safety and what to expect on our FAQs page.

For patients travelling from abroad, the price is confirmed during the free video consultation. You can find more answers on our FAQs page.

Yes, very much so. The lumbar spine sits directly on top of the pelvis. When the pelvis tilts, the spine makes up for it with a curve. This puts extra strain on the muscles and joints on one side. It is one of the most common reasons for persistent lower back pain on one side. Our spine alignment page covers this in more detail.

A specialist radiographer reviews your images and writes a detailed report. The report shows how your pelvis, spine and legs are aligned and points out any areas of concern. You receive the report and can share it with your doctor, physiotherapist or consultant back home to guide your next steps.
