Spondylolisthesis
1. Introduction
Spondylolisthesis is a medical term that describes a change in position of one vertebra (the bones that make up the spine) relative to the vertebrae directly below (1). The most common change in position is an “anterior slip” which simply means that one vertebra appears slightly further forward compared to the one below. This most commonly occurs in the low back (lumbar spine) and over 90% of cases occur at the L5-S1 level (where the 5th lumbar vertebrae connect to the sacrum or tail bone) (2,3).
Spondylolisthesis may occur due to normal, age-associated changes to the spinal joints or due to a stress fracture (a small fracture in an otherwise normal bone due to repeated stress or load). This presentation is seen most often in young, active adolescents who participate in sports that involve jumping and landing, such as basketball and athletics (4).
Spondylolisthesis is graded from 1-4. Grade 1 represents over 75% of cases and is the mildest form of the condition, often with very minimal symptoms. Grade 4 is the most severe form of the disorder that may present with more significant symptoms (6).
Frequently Asked Questions
- Spondylolisthesis is a medical term to describe a slight change in position (usually further forward) of one vertebra relative to the vertebrae below (1).
- It is a rare cause of back pain.
- Research evidence suggests between 3.6%-18% of people may have a spondylolisthesis, but only a small percentage may cause back pain (2).
- No.
- Most cases have only mild symptoms or none at all.
- 75% of cases are classified as “Grade 1” with only a mild change in the vertebrae’s position and are therefore less likely to get worse over time (3,4).
- Less than 10% of people seeking treatment for this condition would ultimately be considered for surgery (4).
- A degenerative spondylolisthesis (due to the normal ageing process of the spinal column) is more common in women than men (4).
- Degenerative spondylolisthesis is also more common in those aged over 50 (3).
- However, it may also be seen secondary to a stress fracture (a small fracture in an otherwise normal bone) inactive adolescents participating in sport (5).
- It may be seen in adults who are either overweight or classed as obese.
- It may also be seen in those with a family history of similar/same condition (4).
- Back pain, most often felt in the low back but occasionally in the neck.
- In more severe cases, low back or neck pain may be accompanied by pain felt in the arms or legs or altered sensation (pins and needles or numbness in the arms or legs).
- Low back or neck pain is often worse with standing or leaning backwards.
- Low back pain is eased by sitting or lying down (3,6).
- Aim to reduce or ensure a healthy weight and body mass index (BMI).
- Participate or engage in exercises to strengthen the back and surrounding muscles.
- Inactive adolescents, ensure there are sufficient rest days or modify training to avoid activities that are painful.
- Take any medication as prescribed to help manage your spinal pain and enable you to participate in rehabilitative exercise (7).
- Degenerative spondylolisthesis cannot be cured so treatment is aimed at managing or reducing symptoms and the impact on the person’s life.
- With the right combination of therapies (including staying active, managing weight, strengthening exercises) the condition will have little or no impact on your daily life.
- In the adolescent population, outcomes are generally good if caught early and activities are modified appropriately (7,8).
We recommend consulting a musculoskeletal physiotherapist to ensure exercises are best suited to your recovery. If you are carrying out an exercise regime without consulting a healthcare professional, you do so at your own risk. Book online with us today to get a programme tailored to your specific needs.
2. Signs and Symptoms
Spondylolisthesis does not always cause symptoms so people may have it without knowing; this is therefore not of concern and does not require action (6). The severity of symptoms also varies from person to person.
Symptoms, when this condition is associated with the low back, may include:
- Lower back pain and stiffness. This pain is often worse with long periods of standing, walking and playing sport. It is often eased by sitting or lying down.
- In more advanced cases, there may be pain, numbness or a tingling feeling from your lower back down your legs. This may indicate irritation or compression of the nerves that exit from the low back.
- In extremely rare cases, compression or irritation around the nerves can affect bladder and bowel function, potentially leading to symptoms such as incontinence or numbness around the genitals, inner thighs or anus (see also “cauda equina syndrome”) (3).
In those cases where a spondylolisthesis is associated with the neck, symptoms may include:
- Neck pain and stiffness.
- Pain that radiates into the shoulder down the arms. There may also be numbness, pins and needles or tingling in the arm, hand or fingers if a nerve has become compressed or irritated.
- In very severe cases, neck pain may be accompanied by clumsiness, loss of grip strength, changes to your walking (such as tripping or falling) or pain that radiates into the legs as well as the arms (1, 3, 5).
3. Causes
There are five categories of spondylolisthesis that refer to the different reasons why this condition may occur (1,9). These are outlined below:
- Degenerative – spondylolisthesis can occur due to normal, age-related changes in the spine. It is usually related to instability and forward movement of one vertebral body relative to the adjacent vertebral body.
- Isthmic – spondylolisthesis is because of defects in the pars interarticularis (a small part of the vertebrae). A possible reason for this includes a stress response in adolescence related to sports such as football, cricket, and gymnastics, where repeated lumbar extension occurs (5).
- Traumatic – spondylolisthesis occurs after major trauma.
- Dysplastic – spondylolisthesis occurs due to natural variation in the way(s) that your bones are formed or aligned.
- Pathologic – spondylolisthesis can be from systemic causes such as bone or connective tissue disorders, cancer or infection (3, 5, 7).
4. Risk Factors
This is not an exhaustive list. These factors could increase the likelihood of someone developing spondylolisthesis. It does not mean everyone with these risk factors will develop symptoms.
- A degenerative spondylolisthesis (due to the normal ageing process of the spinal column) is more common in women than men (9).
- Degenerative spondylolisthesis is also more common in those aged over 50 (9).
- However, it may also be seen secondary to a stress fracture (a small fracture in an otherwise normal bone) inactive adolescents participating in sport.
- It may be seen in adults who are either overweight or classed as obese.
- It may also be seen in those with a family history of a similar/same condition (2, 3).
5. Prevalence
Evidence suggests between 3.6%-18% of the general population may have a spondylolisthesis on imaging. However, as mentioned above, the vast majority of these will not cause pain. 75% of cases are considered “Grade 1” which is the mildest/least severe grade seen (1, 2).
6. Assessment & Diagnosis
Your physiotherapist will take a detailed history of your low back pain to better understand how the pain is affecting you. They may ask you questions about how the pain is at certain times of the day, which activities make it better or worse, and whether you have any symptoms in your leg. The physiotherapist will perform a physical examination, looking at how well you move and how your pain responds to different movements. They may also check the strength and sensation in your legs if this is required.
In cases where symptoms are not responding to usual care, X-rays may be used to look at the alignment of the vertebrae. An MRI (magnetic resonance imaging) scan can also confirm the diagnosis and is more likely to be used if nerve involvement is suspected.
7. Self-Management
Self-management may consist of a period of rest, oral pain relief or non-steroidal anti-inflammatory drugs, heat, light exercise, weight loss and pacing of activities.
As part of the sessions with your physiotherapist, they will help you to understand your condition and what you need to do to help you manage your spondylolisthesis. This may include reducing the amount or type of activity, as well as other advice aimed at reducing your pain. It is important that you try and complete the exercises you are provided as regularly as possible to help with your recovery. Rehabilitation exercises are not always a quick fix, but if done consistently, over weeks and months then they will, in most cases, make a significant difference.
8. Rehabilitation
Your physiotherapist can work with you to devise a programme that suits your needs/goals and help you manage your symptoms.
For this condition, you may be given exercises that will aim to:
- Strengthen the trunk, back and lower limbs.
- Improve the flexibility of muscles around the pelvis and low back (such as the hamstrings).
- Improve your balance and ability to transfer weight effectively when walking.
- Improve your fitness and muscular endurance (7, 8, 10).

Rehabilitation Plans
Our team of expert musculoskeletal physiotherapist have created rehabilitation plans to enable people to manage their condition. If you have any questions or concerns about a condition, we recommend you book an consultation with one of our clinicians.
What Is the Pain Scale?
The pain scale or what some physios would call the Visual Analogue Scale (VAS), is a scale that is used to try and understand the level of pain that someone is in. The scale is intended as something that you would rate yourself on a scale of 0-10 with 0 = no pain, 10 = worst pain imaginable. You can learn more about what is pain and the pain scale here.
This basic rehabilitation programme includes simple exercises to mobilise the spine and begin to strengthen some of the key muscle groups that support your low back. It can be performed little and often during the day within the limits of your pain. Pain should not exceed 3/10 on your perceived pain scale whilst completing this exercise programme.

This more intermediate programme includes some more challenging exercises that will aim to strengthen the muscles that support your low back, as well as helping to strengthen the buttocks, hamstrings and quadriceps. Pain should not exceed 3/10 on your perceived pain scale whilst completing this exercise programme.

This is an advanced programme of exercises to continue to build strength and muscle endurance around your lower limbs and low back. It may be completed 3-4 times per week, like a gym programme, and includes more functional or multi-joint exercises. Pain should not exceed 3/10 on your perceived pain scale whilst completing this exercise programme.

10. Return to Sport / Normal life
This is very much symptom dependent. In those wishing to return to sport or more demanding levels of activity, we suggest a consultation with a musculoskeletal physiotherapist. The physiotherapist can guide you on the appropriate progression of rehabilitation relevant to your goals and construct a phased return to your sport to minimise the chances of recurrent pain.
11. Other Treatment Options
In some cases, particularly advanced cases or where physiotherapy and medications have not helped your pain, you may be recommended surgery (10). This is largely when there are more severe changes shown on scans and where there may be nerve involvement. However, it is worth noting that less than 10% of people seeking treatment for this condition would ultimately be considered for surgery (1, 11).
