Second Opinions for Spinal Surgery

Second Opinion versus Independent Second Opinion:
Watch the Difference!

Asking for additional advice is a common reflex of patients who doubt the diagnosis, feel overwhelmed, or are worried about the suggested treatment strategies. These additional consultations have the goal of clarifying uncertainties around diagnosis or management, particularly when healthcare decisions are complex, unpleasant, and carry considerable risks.

The term “second opinion” is defined as an additional assessment of a medical condition performed by another physician or specialist after an initial medical diagnosis. But there is a major difference between the most typical form of second opinion nowadays actively promoted by hospitals and the “independent second opinion” introduced in the USA as early as the beginning of the 1970’s. In an independent second opinion, the assessment is done by a specialist, who is not allowed to subsequently treat the patient. This ensures impartiality and makes second opinion free of patient recruitment and any economic thoughts.

Back Pain: (Too) High Rates of Surgical Interventions

In the 1970´s several US sickness funds started to require such independent second opinions for particular surgical operations due to unexplained regional differences and excessive surgery rates. The same is true for other countries that have adopted the American model of healthcare. When hospitals are organized as profit-oriented business entities, high-cost treatments generate more revenue than a cautious strategy. Other countries, such as Germany, had a substantial shift in treatments after the refunding criteria for inpatient treatment changed. Decades ago, when a patient with back pain was admitted to a hospital, the hospital got paid based on the length of their stay. Following the implementation of a charge based on medical condition, the back pain patient spent less time in the hospital, but surgery rather than conservative care became more common.

The “need” for spinal surgery for back pain had suddenly nearly doubled. In 2007, 452,000 people in Germany had spinal surgeries. The number climbed to 772.00 in the year 2015. In 2015, there were significantly more large surgical methods, such as stiffening several spinal bones (arthrodesis), compared to 2007. Furthermore, the number of spine procedures performed per capita differed by thirteen times among geographic locations. This cannot be explained by a rapid decline in a certain population’s health. Rather, it suggests that some hospitals preferentially choose invasive surgical treatment.

Background Info: Back Pain and Sedentary Lifestyle

Back pain is frequent. Nearly every one of us will be confronted with it on some days in our lives. Some would say, having some back discomfort comes with age like getting grey hair.

You are not alone in experiencing unpleasant back discomfort. Millions of individuals are facing the same difficulty. Even if the pain is severe, there’s a 90% chance it’ll be gone, or be much better, within six weeks. Most pain settles within a week. In 95% of cases — called unspecific back pain — there is no serious underlying cause.

But unspecific back pain also hurts. As a reaction, we often start to avoid physical activity. However, what is useful in the very short term can lead to extra issues later on. The bones in our back need to be fixed together in a way that keeps them stable, but still allows enough flexibility to allow us moving around. This is possible because we have lots of small bones — the vertebrae — separated by ‘discs’ of tough connective tissue surrounding a squashy center, as well as muscles and ligaments crisscrossing between them. If our spine is not used, the back’s stabilizing muscles are getting more and more weak. If the small vertebral joints are not moved, the cartilage inside obtains fewer nutrients and begins to degenerate faster. While long-term heavy work can also result in spine damage, physical inactivity and a sedentary lifestyle is the most frequent reason for back pain in modern times.

For the majority of patients, physiotherapy and exercise often helps to ease back pain and prevent further discomfort. Stretches can help in the short term to beat the pain. The next step is strengthening the muscles in question to prevent the problem from flaring up again. Improvements may be slow to start with. However, a gradual return to normal activities is the best way to get good short and long term results after a back problem.

Conditions Commonly Linked to Back Pain

Muscle or ligament strain. Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. For people in poor physical fitness, constant strain on the back can cause painful muscle spasms.

Bulging or ruptured disks. Disks act as cushions between the bones in the spine. The soft material inside a disk can bulge or rupture and press on a nerve. However, a bulging or ruptured disk might not cause back pain. Disk disease is often found on spine X-rays, CT scans or MRIs done for another reason.

Arthritis. Osteoarthritis can affect the lower back. In some cases, arthritis in the spine can lead to a narrowing of the space around the spinal cord, a condition called spinal stenosis.

Osteoporosis. The spine’s vertebrae can develop painful breaks if the bones become porous and brittle.

Spondyloarthritis. This inflammatory disease can cause some of the bones in the spine to fuse. This makes the spine less flexible.

Back Pain and Red Flags

The vast majority of patients with acute low back pain suffers from a non-specific musculoskeletal cause with a self-limiting course that will typically improve rapidly within a month and be fully resolved by around 6 weeks.

However, a minority (less than 1 out of 100) of patients will have potentially serious spinal conditions such as fractures, tumors, or spinal infections and cauda equina syndrome that require urgent diagnosis and management. Others may have significant non spinal causes of back pain including infection of the urinary tract, renal colic or an abdominal aortic aneurysm that require just as urgent attention. These serious conditions can be identified in the initial assessment and examination by searching for the presence of any so-called “red flag” features.

Red Flags

History of cancer
History of significant trauma
Intravenous drug abuse
Recent bacterial infection or fever
Immune suppression (HIV, transplant, corticosteroids)
Age <16 or >50 years
Pregnancy
Unexplained weight loss
Persistent symptoms for >4 weeks (recurrent presentations, worsening pain)
Severe pain when supine and/or at night
Saddle anesthesia (loss of sensation restricted to the area of the buttocks towards the inner surfaces of the thighs)
Bladder dysfunction (urinary retention or incontinence)
Bowel dysfunction (fecal incontinence)
Neurological deficit in either or both lower limbs (especially if progressive)

Science: Results of independent second opinion in spinal surgery

Australia — Second Opinion Only a Delay of Surgery?

The analysis of a Brazilian second opinion program performed by Eliane Antonioli from the Albert Einstein Hospital in Sao Paulo took a longer look. A second opinion was offered to 1.088 patients with back pain and a first referral for surgical treatment, and patients were followed-up for two years. The result: Of the 1,088 patients the second opinion program recommended injection treatment for 49 patients (4.5%); conservative management for 662 patients (60.8%) and surgical treatment for 377 patients (34.7%).

Arthrodesis, a complex spine surgery, was the main treatment recommended by first referral (737 patients; 67.7%). Among these patients, the second opinion program instead recommended conservative management for 449 patients (60.9%), and different surgical approaches for 258 patients (35.0%). Arthrodesis recommendation occurred in only 6.0% of the second opinion cases.

The two year follow-up confirmed, that less aggressive therapies recommended by the second opinion resulted in improved patient outcomes and quality of life and also in cost saving for the healthcare system.

Germany — Second Opinion Cuts Down up to 88% of Spinal Surgery

Several research and data analysis from Germany also point out, that independent second opinion can reduce overly aggressive therapy for back pain.

The University of Witten/Herdecke analyzed 1414 patients with an initial recommended surgery of the spine, hip, knee, and shoulder. The independent specialists of the German second opinion provider Medexo did not confirm the initial therapy plan in two out of three cases, but suggested a conservative approach with medication and physiotherapy.

Following a 12 year evaluation of their independent second opinion program before spinal surgery procedures, one of the largest German health insurers (Techniker) reported in 2024 that 88 % of spine surgeries were assessed as unnecessary. Instead, the conditions would have been treatable by physiotherapy.

Facing Spine Surgery? Ask for an Independent Second Opinion!

Second opinions have the goal of clarifying uncertainties around diagnosis or management, particularly when healthcare decisions are complex, unpleasant, and carry considerable risks. Second opinions might be particularly useful for people recommended surgery for their back pain as surgery has at best a limited role in the management of back pain.
