Hip Dislocation & Instability

Overview

What Is Hip Instability & Hip Dislocation?

Hip instability is a loose or wobbly hip joint that’s usually caused by problems with the ligaments (the bands of connective tissue that hold bones or joints together).

In hip dislocation, the ball at the end of the thighbone is pushed out of the socket. This painful condition requires medical treatment.

An accident or injury can cause hip instability or hip dislocation. But in some cases, people are born with structural problems in the hip joint – called hip dysplasia – that can cause the hip joint to dislocate. If this is the case for you, doctors might identify dysplasia at birth, or it might not be noticeable until you’re older.

Whatever the cause of your hip problems, we can help. Our orthopedic specialists and sports medicine doctors will examine your hip and recommend appropriate noninvasive solutions like physical therapy or sports training for hip instability. We also offer advanced surgical options for hip dislocation or instability, from minimally invasive repair to total hip replacement.

    Symptoms

    When Should You See a Doctor for Hip Instability & Hip Dislocation?

    You should see an orthopedic or sports medicine doctor if you:

    • Hear snapping, clicking or popping sounds or sensations (crepitus) in any part of the hip
    • Experience hip pain or pain in the groin
    • Can’t put weight on your hip
    • Can no longer walk normally

    Causes

    What Causes Hip Instability & Hip Dislocation?

    Some people are born with conditions that make hip problems more likely. Others experience athletic injuries or car accidents, both of which can cause hip instability or hip dislocation.

    The most common causes of hip instability include:

    Injuries to Ligaments in the Hip Joint

    Ligaments in the hip joint may be stretched or otherwise damaged because of:

    • Traumatic events, like a motor vehicle accident
    • Rotational instability in dancers or athletes who use extreme ranges of motion

    Hip Dysplasia

    Some people are born with hip dysplasia, in which the ball of the hip joint is loose in the socket. This hip instability may lead to hip dislocation, where the joint slips out of the socket.

    Types of hip dysplasia include:

    • Developmental dislocation (or dysplasia) of the hip (DDH), usually diagnosed at birth or within the first year
    • Adult hip dysplasia, which may be identified when arthritis develops or when a person experiences a dislocated hip

    Genetic Syndromes

    Genetic or inherited syndromes can affect body structures and make hip dysplasia or hip dislocation more likely. These include:

    • Down syndrome, which causes looser ligaments and muscles
    • Ehlers-Danlos syndrome, which causes loose or hyperextensible joints (joints that move beyond a normal range)

    Diagnosis & Treatment

    What to Expect at Your Doctor’s Appointment

    If you’re experiencing hip pain and instability, your doctor will perform a complete physical exam and discuss your symptoms and medical history.

    To understand the cause of the hip instability and find the best treatment for you, your doctor may order tests including:

    • X-rays: These images let your doctor see the fit and condition of bones in your hip joint. X-ray images also help your doctor check for a dislocated hip or other issues.
    • Arthrogram: An arthrogram uses dye injected into the hip joint before X-rays or other scans. This dye helps your doctor clearly see details of the joint’s condition.
    • Computed tomography (CT): A CT scan provides images from many directions, which gives a more detailed view of the hip joint.
    • Magnetic resonance imaging (MRI): MRI scans provide a good visual of the soft tissue in and surrounding the hip joint, including the ligaments.

    Treatments for Hip Instability & Hip Dislocation

    Our doctors will recommend a treatment plan based on the condition of your hip and your overall health. With each of their recommendations, they’ll focus on relieving pain and improving your hip’s function. Find out more about our treatments for hip pain.

    Our doctors may suggest treatments like:

    • Rest or moderate exercise
    • Physical therapy to strengthen the muscles around the hip and improve mobility
    • Minimally invasive surgery – like arthroscopic hip surgery – to tighten the ligaments in the hip
    • Hip preservation surgery for hip dysplasia – a procedure called PAO (periacetabular osteotomy) that reshapes the hip socket so you can avoid total hip replacement
    • Total hip replacement surgery with an artificial hip joint to restore motion and stability
