Spine Surgery Recovery: Precautions and Return to Sport

Recovery after spine surgery, in the protocol of Dr. SK Rajan, Chief - Neuro Spine Surgery & Additional Director - Neurosurgery, Artemis Hospitals, Gurugram, India, is built around a three-month healing period after a discectomy or fusion: no lifting, squatting or bending for three months, X-rays every month for the first three months, then every three months until one year. A return to active sport takes about one year.

Imaging and navigation have transformed how spine surgery is performed, but deciding who should have an operation, who should be treated with medicine, exercise or injections, and how a patient should live in the months afterwards remains a matter of clinical reasoning rather than equipment. Dr. Rajan set out his approach to each of these questions: how patients should protect a repaired spine, how long an athlete needs before returning to sport, when to operate, where pain specialists fit, what keeps a healthy spine healthy, and when a curved spine needs correction. The surgical techniques themselves are covered in the guide to recent advances in spine surgery, and the most common operation in detail in minimally invasive lumbar fusion.

Recovery after spine surgery: infection, hygiene and restrictions

Recovery after spine surgery rests on three things in Dr. Rajan's practice: preventing infection, keeping clean at home and protecting the spine for the three months it takes to heal. He addresses each in turn.

Reducing infection. The first measure is to make the operation as minimally invasive as possible. Postoperative antibiotics are given, and the urinary catheter is removed in good time, because urine is often a major source of infection.

Keeping clean at home. Dressings are changed every second day until day 10, when the sutures are removed. Patients should avoid going out and receiving too many visitors, and should clean the wound and body by sponging rather than bathing.

Protecting the spine while it heals. After a simple discectomy (removal of the part of a disc pressing on a nerve) or a spinal fusion, healing takes about three months, and the restrictions run for that period:

• No lifting weights, sitting on the ground, squatting, bending down or lifting children for three months.
• In the first month, no sitting for more than half an hour continuously; the patient should get up, take a short break and then sit again. Car journeys follow the same rule: no more than half an hour without stopping, getting out and taking a break.
• For the first 7 to 10 days, no sitting on a sofa or a low seat. An armchair allows the patient to rise with the support of the arms.
• A belt is worn after lumbar surgery and a collar after cervical surgery.

Follow-up X-rays after spine surgery

Follow-up imaging is structured. X-rays are taken every month for the first three months, then every three months until one year. These are sent to Dr. Rajan's team through the partner or referring doctor, and a record of every patient's scans is maintained. Restrictions are lifted progressively as the months go by.

Return to sport after spine surgery

Returning to active sport after spine surgery takes about one year in Dr. Rajan's practice, roughly nine months of it rehabilitation, a timeline he set out in the masterclass live discussion. Golfers, cricketers, gym trainers and climbers are not unusual among his patients, and their surgery is planned differently from the outset.

The first priority is stability. For an office worker with a simple slipped disc, he does what the disc requires. For a sportsman, a gym trainer or an adventure-sports enthusiast who wants to climb mountains, he leans towards spinal fixation to give the spine the stability it will need under load, and in his view that stability is how most sportsmen get back to active sport. The second principle is that the surgery should be minimally invasive wherever possible, so that the muscle is not badly damaged.

The return is slow. Dr. Rajan puts the time to active sport at about one year, of which roughly nine months is rehabilitation focused on core training, lower back exercises and the neck muscles, to build a core strong enough to take the load. This work is always supervised by sports physical therapists, using set protocols adjusted to the individual's body profile.

Spine surgery or medical management: how the decision is made

In Dr. Rajan's framework, pain of less than about three to four months without weakness warrants a trial of medical management, while long-standing or recurrent symptoms with weakness or a declining quality of life, matched by nerve compression on MRI, point to surgery. Whether to operate or to continue medical management is a question on which doctors' opinions vary widely, and he places patients along a spectrum.

At one end is the patient with acute pain of relatively short duration, less than about three to four months, with no weakness and a quality of life that is not severely compromised. That patient should have a trial of medical management: precautions, posture correction, exercises, physiotherapy, medicines and possibly injections.

At the other end is the patient who has suffered for a long time and has tried all of these without lasting benefit, or whose attacks keep returning. Such patients may develop weakness in a foot or an arm, or changes in their handwriting. Or their quality of life deteriorates: they cannot travel or take a holiday, lift their children, go for a walk or play badminton. When that picture is matched by corresponding nerve compression on MRI, the conversation changes. Surgical decompression and stabilisation will then improve quality of life more than continuing with physiotherapy and exercises that are not working.

The same disease, different lives

Between the two ends lies a large grey zone, and Dr. Rajan is candid that it will always exist. Lifestyle demand is a deciding factor. He describes a 70-year-old who lives above their own shop, has no wish to travel and is looked after within a joint family; for that person, medical management is entirely reasonable. Another person of the same age with the same disease who wants to travel the world, or who needs to stay socially or politically active, will need surgery.

This, in his view, explains why opinions vary so much between doctors. Some decide on the clinical examination alone: no weakness, no surgery. Others weigh the patient's whole journey, including the steady erosion of quality of life. Treatment has to be individualised.

When to refer to a pain specialist

Many of Dr. Rajan's patients end up being referred for injections to a pain specialist, and he regards the two disciplines as complementary rather than competing. An abnormality on MRI does not mean everyone needs surgery, and at certain stages of disease many patients benefit more from pain medicine.

His referral logic is specific:

• No significant compression. If the MRI shows little nerve compression and the pain is not improving with medicines or exercise, that is where the pain specialist has a role.
• Compression, but surgery is not an option. When there is compression, he refers for pain management only if the patient cannot undergo surgery because of a serious medical condition, such as end-stage liver disease.
• Compression, but the patient is not ready. Some patients want relief now and are not ready to accept surgery. An injection can give a few weeks of relief while they weigh the pros and cons of each approach.

A combined approach also works for patients who are poor surgical candidates today. For an obese patient with poor bone quality, intense pain and, according to the family, no prospect of exercising, an injection can provide some relief. At the same time, the team starts improving bone health and muscle mass, including with protein supplements, and ultimately takes the patient to surgery.

Protecting the spine: desk workers, weightlifters and older adults

Dr. Rajan's prevention advice turns on posture, core strength and, for heavy lifters, respecting the time a damaged disc needs to heal.

Desk workers

For adults between about 30 and 60, leaving aside extremes such as severe obesity or very advanced age, the rules are largely the same. For anyone sitting through long working days, posture comes first: back support, the laptop raised to a higher level, the arms well rested and the spine supported, with back support in the car as well. The seat should not be low. The angle between the thigh and the lower leg should be more than 90 degrees, obtuse rather than acute, because sitting low reduces that angle and increases the load on the spine.

Dr. Rajan recommends a set of basic exercises for everyone: pelvic tilts, leg raises, windshield-wiper movements of the legs, the Cobra pose and the Superman pose. Together they strengthen the lower back and build the stamina needed for long hours of sitting.

Weightlifting after a disc prolapse

For heavy weightlifters, the answer depends on the diagnosis. A lifter with back pain and a largely normal MRI can return to active weightlifting in six to eight weeks, which is more a matter of physiotherapy and exercise than surgery. A prolapsed disc is a different situation: weightlifting is practically ruled out for the next six to nine months. The tear in the annulus, the tough outer ring of the disc, takes about nine months and sometimes a year to heal, and loading it too soon carries a very high chance that the tear ruptures and the disc comes out.

Older adults and core strength

The very elderly need to be especially careful to take extra protein supplements and do resistance training to maintain muscle strength; otherwise they gradually begin to slouch.

The underlying science has shifted within Dr. Rajan's own career. When he trained as a neurosurgeon, some 15 to 20 years ago, there was little understanding of why some people develop spinal problems and others do not. In his view, it has since become clear that the major contributor is a lack of muscular support around the abdomen and lower back. Resistance training helps substantially: many of his patients at an early to moderate stage, with no weakness and a reasonable quality of life, have avoided surgery by strengthening their core.

Scoliosis surgery: when the Cobb angle calls for correction

In Dr. Rajan's practice, a scoliosis curve of around 40 degrees, or one that moves outside the zone of spinal balance, usually signals the need for surgery. Scoliosis is defined by the Cobb angle, the angle of the curve measured on an X-ray. Below 10 degrees, a curve is not labelled scoliosis at all. A curve between 10 and about 25 degrees is managed by observation, with repeated X-rays over the years; in a child who is still growing, a curve of about 25 to 40 degrees is usually treated with a brace to slow its progression.

In his practice, around 40 degrees is usually the tipping point at which it becomes clear that the patient will need surgery. The timing matters: if a curve reaches about 40 degrees after the spine has finished growing, at 18 or 20 years of age, it is not a major cause of concern, because curves below about 50 degrees at skeletal maturity rarely progress significantly, and watchful waiting is usually appropriate.

The Cobb angle is not the only measure. The second is spinal balance. In his description, two parallel lines are drawn on either side of the vertebrae to define a central zone of stability. As long as the curve remains within that zone, it is safe. Once the curve moves beyond it, he considers the chance of rapid progression very high, and scoliosis correction is required.
