Back pain on one side? It could be coming from your hip.

Lower back pain is the single most common musculoskeletal complaint in the world. Up to 85% of the population will complain of low back pain at some stage in their lives. It is also the 3rd most common reason people will visit a GP.

Lower back pain can be broken into 2 broad types.

  1. Central Low Back Pain – pain that does not dominate one side and is experienced generally across the entire lower back region.
  2. Unilateral Low Back Pain – pain that is experienced on one side only.

It is this second that we are going to talk about.

Whilst there are other possible causes of unilateral low back pain, the most common cause we see is actually the hip. The reason is that when we load the lower limbs in tasks such as getting out of a chair, walking, running, climbing stairs, this load is transferred from the ankle, through the knee, then to the hip and then finally the lower back. If the hip is not functioning optimally, this load will bypass the hip and be transferred straight into the lower back on the same side.

Because the hip has significant movement in all 3 planes (forwards, backwards, side to side and rotation) it plays a much more complex role than the ankle and knee which move predominantly in 2 and 1 planes respectively. Back pain on one side can also be attributed to the ankle or knee but these are less common causes.

What does the evidence say?

Sadeghisani and colleagues in 2015 conducted a review of all the published literature of hip range of motion and its relationship to low back pain. They concluded that hip range of motion testing, particularly hip internal rotation, should be a standard, routine part of an examination for patients with low back pain.

Eyvazov and colleagues in 2016 conducted a study on 28 patients booked in for a hip replacement found that their concomitant lower back pain was reduced by 50% after their surgery.

A study earlier this year by Prather and colleagues on 101 patients with low back pain found that those with positive hip examination findings (predominantly reduced hip flexion and internal rotation range of motion), had more pain and poorer function compared to those with normal hip findings.

Sorenson and collegues (2016) found that asymetrical performance of hip abduction (moving the leg out to the side) was a significant risk factor for people that get low back pain when standing.

How do we find out if your hip is the problem?

There are 2 parts to the assessment.

  1. Assessment of your lumbar movements in positions that you have reported to be a problem. For example if you get your pain during or after running, then we’ll get you on the treadmill to have a look at what happens around the hip when you run. If you get the pain simply getting out of a chair, then we’ll examine that movement. We will often find that due to reduced hip function, there are abnormal compensatory movements that occur in the lumber spine.
  2. Assessment of hip strength and range of motion on the same side. Often if the pain is related to the hip, there will be deficits in either strength or range of motion or both, on the same side as your pain. Studies show that the 2 most important movements to assess are hip flexion and hip internal rotation.

If you are suffering from lower back pain one one side then don’t be afraid to get in touch with us to have your hip checked out.
