Welcome to the third Spine Research Roundup. Every fortnight we explain a few new studies that matter to people with back and neck problems. This edition covers papers added to PubMed between 18 and 31 October 2026.

1. Slipped discs that shrink on their own

A slipped disc can shrink over time, which doctors call resorption. A team at one hospital in Suzhou, China, looked back at 578 people with symptoms from an extruded or sequestrated lumbar disc, the types where disc material has pushed well out of place. They were managed without surgery at first and followed for at least 2 years. Shrinkage, defined as at least a 30% fall in volume on scans, was seen in 256 people (44.3%), at a median of about 8 months. Only 0.8% of them went on to have surgery, compared with 24.0% of those whose disc did not shrink. Pain and disability improved more in the shrinkage group after the first 6 months. People also improved without shrinkage, and the amount of shrinkage showed no consistent link with how they did. This was a look back at records from a single centre, so it shows a link rather than proof of cause.^[1]

What this means for patients

A disc that looks dramatic on a scan does not automatically mean you need an operation. NICE advises considering decompression surgery for sciatica when non-surgical treatment has not improved pain or function and the scan findings fit your symptoms.^[8] If you have sciatica on both sides, weakness or numbness in both legs that is severe or getting worse, numbness around your genitals or bottom, or you cannot pee or cannot control when you pee or poo, go to A&E or call 999 straight away. These can be signs of cauda equina syndrome.

2. First treatment for sudden back pain, and later opioid problems

US researchers looked back at the Medicaid records of 399,500 adults under 65, not previously on opioids, who started pain treatment within a month of a new diagnosis of acute low back pain. Within 13 months, 2.3% had a new diagnosis of opioid use disorder or overdose. Starting higher-dose opioids was linked with the biggest rise in that risk (146.6% higher). Starting lower-dose opioids for more than 7 days, or gabapentinoids, was linked with about double the risk (105.2% and 101.6% higher). Starting chiropractic care or physical therapy was linked with a lower risk (32.8% and 31.1% lower). These are relative figures from insurance records. People who get different treatments may differ in other ways, so this shows links rather than proof of cause, and US Medicaid patients may not reflect UK patients.^[2]

What this means for patients

NICE says do not routinely offer opioids for acute low back pain. It allows a weak opioid to be considered only if an anti-inflammatory medicine is unsuitable, not tolerated or has not worked. It says do not offer opioids for chronic low back pain or chronic sciatica, and do not offer gabapentinoids for low back pain or sciatica. It suggests considering manual therapy, which includes spinal manipulation, only alongside exercise.^[8] Please do not start, stop or change any medicine because of this study. Talk to your GP or pharmacist first.

3. Yoga, Pilates, tai chi or qigong: does the type matter?

Researchers in China pooled 25 randomised trials of mind-body exercise in adults with chronic non-specific low back pain. Compared with control groups, these exercises lowered pain by an average of 1.56 points on a 0 to 10 scale. Results varied a great deal between trials, so some people may see little or no benefit. No difference was detected between the four types. The authors say the evidence does not establish a preferred type or an ideal amount of exercise. Certainty was low for all of these comparisons.^[3]

What this means for patients

NICE suggests considering a group exercise programme for a specific episode or flare-up of low back pain, which can be biomechanical, aerobic, mind-body or a mix, chosen to suit your needs, preferences and abilities.^[8] A class you enjoy and can keep going to is a sensible place to start.

4. Which back pain treatments are good value?

An Australian and UK team reviewed 20 economic studies of non-drug, non-surgical treatments for non-specific low back pain, compared with usual care. Most treatments were cost-effective at a threshold of £20,000 for each year of good quality life gained. Help aimed at reducing fear and stress or supporting self-management in chronic low back pain looked potentially cost-saving. So did clinician-delivered yoga, acupuncture and cognitive therapy. All the evidence came from high-income countries and the studies were very mixed.^[4]

What this means for patients

One finding differs from UK guidance. NICE advises against offering acupuncture for low back pain or sciatica. In July 2026 NICE also removed its recommendations on psychological therapy and combined programmes, as they may be out of date. What NICE does advise is self-management information, encouragement to continue with normal activities, and considering group exercise.^[8] Those are good things to ask your GP or physiotherapist about first.

5. Cervical myelopathy may be more common than we thought

Cervical myelopathy happens when wear in the neck presses on the spinal cord. A team led from Exeter searched English general practice records for adults aged 20 and over from 2013 to 2023. They found 10,439 new diagnoses among 16.6 million registered patients, or 7.9 per 100,000 people each year. Rates were higher in men, peaking at age 75 to 79. The authors say this is higher than earlier estimates, which mostly came from hospital records. The study counts only diagnoses recorded by GPs, so people not yet diagnosed are missed.^[5]

A second study followed 501,936 UK Biobank volunteers for a median of 16 years. It found 978 cases in hospital records, or 12.31 per 100,000 people each year, so current estimates run from about 8 to 12 depending on who is counted and how. Slow walkers had about 2.5 times the risk of brisk walkers, and stronger grip was linked with lower risk. The authors say these measures are non-specific and should not be used as screening tests.^[6]

What this means for patients

Slow walking or a weak grip has many possible causes and does not mean you have myelopathy. See your GP if your hands are becoming clumsy or numb, or your walking is getting unsteady. If you have a sudden or rapid worsening of hand clumsiness, weakness or walking, or new loss of bladder or bowel control, go to A&E or call 999 straight away.

6. Is keyhole surgery better for a narrowed lower spine?

A UK team reviewed 12 randomised trials, with 1,212 participants, comparing endoscopic (keyhole) decompression with non-endoscopic decompression for lumbar spinal stenosis, without fusion. At 12 months, endoscopic surgery looked slightly better on the Oswestry Disability Index, by 4.54 points in 4 trials with 302 people. However, one trial with reporting concerns supplied 95.1% of that result. Without it, the difference was 3.74 points but could have favoured either operation, with low certainty. The authors conclude that endoscopic surgery has not shown a reliable lasting advantage in disability, pain or safety, and that their findings do not establish equal safety. It was also registered only after the event.^[7]

What this means for patients

A smaller cut does not guarantee a better result a year later. That does not make endoscopic surgery wrong for you, only that the evidence is not yet secure. The authors suggest the choice should rest on how much decompression is needed and on the surgeon’s expertise. Those are fair questions to ask if you are offered decompression surgery.
