At a glance
A hip dysplasia assessment is a structured orthopaedic evaluation that determines whether the hip socket is too shallow or poorly angled to hold the ball of the thigh bone securely. The hip is a ball-and-socket joint: the rounded head of the femur (thigh bone) sits inside a cup-shaped socket in the pelvis called the acetabulum. When the acetabulum does not cover enough of the femoral head, the joint is unstable and the cartilage that lines it wears down faster than normal.
The assessment combines a physical examination with imaging, usually X-rays and sometimes an MRI (magnetic resonance imaging, a scan using magnets and radio waves), to measure the exact shape and angle of the socket. Those measurements tell the orthopaedic surgeon how severe the dysplasia is and whether, or how urgently, treatment is needed.
Medical Condition
Doctors request a hip dysplasia assessment when a patient has hip pain, instability, or movement problems that suggest the joint may not be properly formed. The condition can first appear in infancy, be missed, and then cause symptoms in adolescence or early adulthood. It can also be identified on a routine newborn check.
- Newborns and infants with a positive Ortolani or Barlow test (clinical signs of hip instability found during a physical exam)
- Children or teenagers with a limp, uneven leg length, or restricted hip movement
- Young adults with groin pain or clicking in the hip during activity
- Patients with early hip arthritis (joint inflammation and cartilage loss) that began at an unusually young age
- People with a family history of hip dysplasia who are experiencing symptoms
- Athletes with unexplained hip or groin pain that does not improve with rest
The assessment is generally not performed as a standalone test in patients whose hip pain is clearly explained by another confirmed diagnosis, such as a recent fracture or advanced osteoarthritis (severe joint degeneration) already visible on existing scans. In those cases, the cause is already known and further assessment for dysplasia would not change management.
Risks & Complications
A hip dysplasia assessment is a diagnostic evaluation and carries very little risk by itself; any risks are mainly tied to the imaging used rather than the assessment as a whole.
- Low-dose radiation from X-rays: the dose used for hip imaging is small, but doctors usually avoid repeated X-rays in pregnant women or very young children unless necessary
- Discomfort during the physical examination: the examiner moves the hip into various positions, which can cause temporary pain if the joint is already inflamed
- Claustrophobia or anxiety during MRI: the scanner is a narrow, noisy tube and some patients find it distressing
- Contrast dye reaction (if an MRI arthrogram, meaning contrast fluid injected into the joint, is requested): mild allergic reactions such as skin redness or itching are uncommon, and severe reactions are rare
- Temporary soreness at the injection site if contrast dye is used for the arthrogram
Preparation & Procedure
For a standard hip dysplasia assessment involving only a physical exam and plain X-rays, there is usually no need to fast or stop any medication beforehand. If an MRI is planned, patients are asked to remove all metal objects such as jewellery, piercings, and hearing aids before entering the scanner room, and to inform the radiographer of any metal implants in the body.
If an MRI arthrogram (an MRI combined with a contrast injection into the joint) is scheduled, the clinic will give specific instructions. Blood thinners may need to be paused for a short time before the injection, but this decision is always made by the referring doctor based on the patient's full medical history. Wearing loose, comfortable clothing makes the physical examination and changing into a hospital gown easier.
The following tests and imaging are typically gathered as part of the assessment:
- Weight-bearing pelvic X-ray: taken while the patient stands, to reflect the true load on the joint
- False-profile X-ray: a side-angle view that shows how much of the femoral head is covered at the front of the socket
- MRI of the hip: shows the labrum (the ring of cartilage around the socket edge) and soft tissues in detail
- MRI arthrogram (in selected cases): contrast fluid injected into the joint before MRI to outline the labrum more clearly
- CT scan (computed tomography, a detailed cross-sectional X-ray): sometimes used to measure the three-dimensional orientation of the socket and femoral head
The assessment itself usually follows these steps:
- 1. The orthopaedic surgeon reviews the patient's history, including when symptoms started, which activities make pain worse, and any family history of hip problems.
- 2. A physical examination is performed: the surgeon checks leg length, watches the patient walk, and moves the hip through a range of positions to test stability and reproduce symptoms.
- 3. The patient is taken to the radiology department for X-rays, which are taken in one or more positions as requested.
- 4. If MRI has been requested, the patient moves to the MRI unit. The scan itself usually takes between twenty and forty-five minutes depending on the protocol used.
- 5. If an arthrogram injection is needed, a radiologist (an imaging specialist) injects a small amount of contrast fluid into the hip joint under X-ray or ultrasound guidance, and the MRI scan follows.
- 6. The orthopaedic surgeon reviews all images, takes standardised angle measurements such as the lateral centre-edge angle (which shows how far the socket extends over the femoral head), and discusses findings with the patient at a follow-up appointment.
Aftercare
A hip dysplasia assessment is an outpatient evaluation, so most patients go home the same day, usually within a few hours of arriving. If an arthrogram injection was given, mild soreness and swelling in the hip joint are normal for a day or two.
- If only X-rays or a standard MRI were done, no physical restrictions apply and normal activities can resume straight away
- After an arthrogram injection, most clinics advise avoiding strenuous exercise or heavy lifting for 24 to 48 hours to let the contrast fluid settle
- Ice applied over the hip for short periods can help with post-arthrogram soreness; the clinic will advise on how to do this safely
- A follow-up appointment with the orthopaedic surgeon is scheduled once all imaging results have been reported, usually within one to two weeks
- At the follow-up, the surgeon explains the measurements, discusses whether treatment is recommended, and if so, outlines the options ranging from physiotherapy (exercise-based rehabilitation) to corrective surgery
- If surgery is being considered, further pre-operative assessments such as blood tests or a formal anaesthetic review may be arranged at that point
Cost & What Determines It
The cost of a hip dysplasia assessment varies widely because it is not a single fixed test. The final bill depends on exactly which imaging is ordered, how many specialist consultations are involved, and the hospital setting in which the assessment takes place.
- Complexity of imaging required: a plain X-ray alone costs far less than a protocol that also includes MRI and CT scanning
- Whether an arthrogram injection is needed: adding contrast injection involves a radiologist's fee, contrast materials, and sometimes a procedure room charge
- Hospital class and country: a private orthopaedic hospital in a major city in a high-income country charges significantly more than a regional or public-sector facility
- Number of specialist consultations: some assessments involve only the orthopaedic surgeon, while others require a radiologist, a physiotherapist for functional testing, or a paediatric orthopaedic specialist for children
- Repeat imaging: if earlier scans from another hospital are not available or not of sufficient quality, new images must be obtained, adding to the cost
- Urgency: an expedited appointment or after-hours reading of results by a specialist typically attracts a premium
A package at a private hospital abroad may include the specialist consultation, selected X-rays, and the radiologist's report. MRI, CT, arthrogram injections, physiotherapy assessments, and second-opinion consultations are often billed separately. Patients should ask the hospital for a written itemised quote that lists exactly which components are included before any appointment is confirmed.
BPJS Kesehatan does not cover medical procedures performed outside Indonesia, and most Indonesian private health insurance policies also exclude overseas treatment. Patients who travel abroad for a hip dysplasia assessment generally pay out of pocket or through an international private health insurance policy that explicitly covers overseas specialist care. Requesting a written cost estimate from the hospital before travelling is the most reliable way to understand the full financial commitment and avoid unexpected charges on arrival.
Frequently Asked Questions
Does a hip dysplasia assessment hurt?
Most parts of a hip dysplasia assessment are not painful. The examination usually involves the doctor moving your hip through different positions and taking imaging scans such as X-rays or an ultrasound (a scan that uses sound waves, not radiation), which are generally painless. Some positions during the physical examination may feel slightly uncomfortable if your hip is already sore.
How do I prepare for a hip dysplasia assessment?
Preparation is usually simple and your doctor will give you specific instructions beforehand. For most assessments, no fasting is required, though if sedation is planned (common in young children), the doctor will advise avoiding food and drink for a set period before the appointment. Wearing loose, comfortable clothing that allows easy access to your hip area will help the examination go smoothly.
How long does a hip dysplasia assessment take?
A hip dysplasia assessment usually takes between 30 minutes and one hour, depending on which tests are included. A physical examination alone is quicker, while adding imaging such as an X-ray, ultrasound, or MRI (a scan that uses magnetic fields to create detailed images) will take longer. Your doctor will tell you in advance which tests you need so you can plan your day.
How much does a hip dysplasia assessment cost?
The cost depends on several factors specific to your situation, including which imaging tests are ordered (ultrasound, X-ray, or MRI), the class of hospital or clinic, and whether a specialist consultation is included in the same visit. A written estimate from the hospital will give you the most accurate figure for your individual assessment plan.
