Common, usually mild, and serious back injury is rareStrong evidence
The NHS says "Back pain often improves on its own within a few weeks". Back pain is common in both games: "The overall, 12-month prevalence of LBP for the three sports was 60%: field hockey 56%, football 64% and speed skating 60%" in young Dutch elite athletes (LBP is low back pain), 44% of UK Premier and Division One field hockey players reported it, 24.2% of Swedish elite ice hockey players had a lower back problem in a season, mostly from overuse, and 60.1% of Slovak professional ice hockey players reported it.
It's usually mild: in German elite athletes, average back pain over 3 months was 2.1 out of 10 in field hockey and 3.4 in ice hockey. In South African schoolboy players, "Most participants (79.1%) did not classify their pain as a disability", and the commonest duration was a few hours. Each study counted back pain its own way.

Back injuries are a small share of hockey injuriesEmerging evidence
Across 22 field hockey cohorts, the trunk was 0% to 16% of injuries, and "The majority of injuries were in the less severe category in all studies reporting days of time loss due to injury". In women players, the torso was 1% of acute injuries, though 59% reported back pain. In ice hockey, spine or trunk injuries were 7.8% of injuries at men's world championships, "The majority of players who were injured returned to play within 1 week (53.8%)", and the lower back was about 1.8% of acute injuries in Finland's top league. In US college ice hockey, about half of back, neck and spine injuries were in the lower back, with "notably low rates of fractures and severe spinal injuries".

Both games are played bent forward, but the crouch isn't shown to cause back painMixed evidence
"Unique requirements of field hockey include dribbling the ball and moving quickly in a semi-crouched posture": players spent 89.26% of match time with the trunk bent 20 to 90 degrees, and while dribbling, the spine shortened by 0.4 mm a minute, faster than in other activities measured (a small 1990 lab study). In ice hockey, "Hockey players spend most of their time on the ice in a forward-flexed position". The drag flick, the field hockey penalty corner shot, uses "significantly greater lateral flexion (P < 0.002) and rotation of the lumbar spine (P < 0.006) compared to a hit".
But load isn't the same as harm. In US college women, "The incidence of LBP was 56% (50/90) in the female FH players and 55% (54/98) in the controls" (FH is field hockey), and the authors wrote that "postures associated with field hockey do not appear to significantly increase the incidence of LBP in this population". No study shows the hockey crouch causes back pain.

What goes with back pain in hockey (associations, not proven causes)Emerging evidence
Across sports, "A previous episode of LBP, high training volume, periods of load increase and years of exposure are common risk factors". In 432 adult field hockey players, "drag flickers had significantly higher prevalence of hip (OR: 1.541; 95% CI: 1.014, 2.343) and lower back injury (OR: 1.564; 95% CI: 1.034, 2.365) compared to non-drag flickers" (OR is the odds ratio), but at Hockey Australia's under-18 championships "There was no relationship between drag flicking and injury". In one small survey of UK players, the shortest sticks (35.0 to 35.5 inches) went with almost five times the odds of back pain, from small groups.
In ice hockey, one cohort of 289 player-seasons (33 cases of back pain) found "Of 172 players with hip flexor tightness, 27 (15.7%) developed LBP compared with 6 of 117 (5.1%) with normal flexibility"; whether stretching changes that hasn't been tested.

Young players: the stress fracture of the lower spineEmerging evidence
In an elite US junior ice hockey programme (players aged 15 to 18), "Over 9 hockey seasons, 25 players presented to medical staff with low back pain. Of those, 44% were confirmed to have lumbar spondylolysis", and "Reproducible pain on extension was documented for 9 of the 11 players (82%)" (pain leaning back). In a sports clinic, 47% of adolescent athletes with back pain had spondylolysis, against 5% of adults. Our suggestion, from the ice hockey study: in a young player, back pain that's worse leaning back and won't settle deserves the check the warning signs describe.
No study of spondylolysis in young field hockey players was found. Back pain is common in all teenage athletes (a 12-month prevalence of 42%), and in a US clinic, "Baseball was the only sport to demonstrate a significant increased risk of spondylolysis". The NHS says a stress fracture is more common in young athletes and gymnasts.

Serious spinal injury: rare, and mostly from the boardsEmerging evidence
Canada's registry recorded 355 spinal injuries in ice hockey from 1943 to 2011, most in the neck, most from hitting the boards and about a third from a check or push from behind. "Between 2006 and 2011, 44 cases occurred, 4 (9.1%) of which were severe", across all of Canada's registered players, "still at lower rates than the peak years 1982 to 1995". The registry's authors link the fall with education and rules against checking from behind; these are case counts over time, not a trial.

When a scan matters, and what changes on scans meanStrong evidence
Most back pain after hockey needs no scan. The National Institute for Health and Care Excellence (NICE) says "Do not routinely offer imaging in a non-specialist setting for people with low back pain with or without sciatica", and "The prevalence of disk degeneration in asymptomatic individuals increased from 37% of 20-year-old individuals to 96% of 80-year-old individuals".
A young player with lasting back pain that's worse leaning back is different: the NHS says a GP may arrange an X-ray, with other scans such as a magnetic resonance imaging (MRI) scan for leg symptoms, and an imaging review concluded "MRI should be used in early diagnosis and CT in more persistent courses", while noting thin evidence (CT is computed tomography). In the hockey series, plain X-rays found fewer than half the fractures, and "The early detection of spondylolysis results in a higher likelihood of bony union and a decreased likelihood of spondylolisthesis".

What usually happensEmerging evidence
Most back pain improves within a few weeks, and in schoolboy players it often lasted a few hours. After a young athlete's stress fracture, return varies widely: "Average return to play was 8 weeks. Ninety-six percent of players continued to play at an elite level" in the series of 11 ice hockey players, while times across other studies ran from about 2 to 7 months. Across 11 studies, "Adolescent athletes RTP 92.2% of the time with nonoperative management" (RTP is return to play).
"83.9% of patients treated nonoperatively will have a successful clinical outcome after at least 1 year. Bracing does not seem to influence this outcome." After a mean of 8 years, "Of competitive athletes, 91% returned to their preinjury sport at the same level or higher", and in children followed for 45 years, "Subjects with pars defects follow a clinical course similar to that of the general population."

When it isn't hockey: the causes the warning signs cover
Some back and neck pain has causes hockey didn't create, or needs more than a plan, and the warning signs follow the pages behind them. Numbness around the genitals or bottom, bladder or bowel changes or symptoms in both legs can be cauda equina syndrome, as the NHS back pain and sciatica pages say. After a collision or a hit into the boards, the UK grassroots concussion guidelines, World Rugby and the Gaelic Athletic Association (GAA) agree that only trained healthcare professionals should move a player with a suspected neck injury, Hockey Canada's protocol says the same, and burning, tingling or weakness in both arms or the legs can be a brief injury to the spinal cord, as the stingers studies and reviews describe; NHS inform, NICE and the NHS's cervical spondylosis page set the 999 signs after a neck injury.
A fall where someone can't get up follows the NHS falls page, and a new blow to the back NHS inform's back problems page. A burst aortic aneurysm, a kidney infection, foot drop and back pain with cancer follow the NHS pages and NICE's guideline on spinal metastases, and leg weakness that is getting worse follows a Leicestershire NHS physiotherapy leaflet. A hot, swollen joint can be an infection, as the NHS septic arthritis page says, and fainting or chest pain during exercise needs a 999 call, as the NHS fainting and chest pain pages say. A young athlete's stress fracture, children's back pain, inflammatory back pain and a spinal fracture after a minor fall follow the long-term spondylolysis cohorts and the field hockey studies, the NHS spondylolisthesis page, two NHS children's physiotherapy services, the NHS ankylosing spondylitis page, NICE and the osteoporosis guidance. The back hub's pain rule follows the World Health Organization (WHO) guideline, a review of leg symptoms that move back towards the spine and a review of exercising into pain, and the young athletes' rule the 2026 trial, a review of non-surgical care and the Chartered Society of Physiotherapy's (CSP) myth busters.
