Common, usually settles, and most players are back within a day or twoEmerging evidence
A sore back after a game, a tournament or the first practices of a season is common, and it usually settles. The NHS says back pain "usually improves within a few weeks", and in a new episode of low back pain, average pain fell from 52 to 23 out of 100 within 6 weeks.
In US college basketball, "The majority of both female (58.9%; n = 1004) and male (73.1%; n = 2353) athletes returned to play within 24 hours of injury" after a low back injury. In NBA injury reports from 2021 to 2024, "Nonsurgical management was utilized in 98.78% of cases" of back and neck problems, with "median missed games ranging from 1 to 2". Across 11 studies, the trunk and spine were 7.5% of basketball injuries, and "Only 5% of all injuries reported for children and adolescents occurred in the trunk and spine".

Is basketball hard on backs? The studies disagreeMixed evidence
Whether basketball is a high or a low risk sport for back pain is conflicting, and both views have support. Across sports, the high-quality studies in one review found the lowest point prevalence of low back pain in basketball (18%). Back pain is common in athletes in general: about half of adult athletes report it over a year.
Other studies find it common in players too. In 401 young Finnish club players, "Forty-four percentage of the basketball players and 62% of floorball players had suffered from LBP during the previous 12 months" (LBP is low back pain). A pooled analysis of basketball studies put low back pain at 26% (an interval of 16% to 37%), but the studies asked about different time frames, so the figure is rough. The authors of a German survey of elite athletes suggest that in basketball "the high frequency of jumps and landings" might promote back pain, though only 21 basketball players took part. Taken together, back pain is common in players, as in other athletes, but basketball doesn't stand out as especially hard on backs (our reading).

Tired muscles, strains and bruisesEmerging evidence
Basketball changes movement constantly: in 8 elite Australian men, "The mean (+/- S.D.) frequency of all activities was 997 +/- 183, with a change in movement category every 2.0 s". Over 17 NBA seasons, "Lateral ankle sprains were the most frequent orthopaedic injury (n, 1658; 13.2%), followed by patellofemoral inflammation (n, 1493; 11.9%), lumbar strains (n, 999; 7.9%), and hamstring strains (n, 413; 3.3%)".
In NBA injury reports from 2021 to 2024, "The 4 most common injury types were soreness (26.83%), spasm (23.48%), tightness (12.80%), and contusion (11.59%), collectively representing nearly 75% of injuries". In US college basketball, 61.1% of low back injuries were recorded as pain and 18.4% as bruises, and "Contact injuries were the most common injuries in both women (39.8%) and men (39.8%)": a knee, an elbow or a fall onto the court. These counts come from athletic trainers and public injury reports, so they show how common each problem is, not what causes it.

Jumping, landing and reboundingEmerging evidence
A modelling study of more than 600 tasks found "Especially ballistic jumping and landing skills yield high estimated compression at L4/L5 of more than ten times body weight" (L4/L5 is a joint low in the spine), and 50 drop jumps shortened the spine by about 0.6 mm, a small change that reverses. Jumping takes only about 2.1% of live time in junior elite games, and each landing is brief.
But in 383 young Finnish players followed for 3 years, "we did not find an association between LBP and vGRF" (how hard they landed), though a little less hip and pelvis control on one-leg landings went with later back pain. These are lab and modelling studies, and one cohort: they show the load, not that landing causes back pain.

Young players: back pain often comes with leg pain, and comes backEmerging evidence
In young Finnish players, most back pain came during the playing season, and a family history of muscle and joint problems and older age went with it. Back pain that a study doctor confirmed was much rarer, "87 per 1000 athlete-years", but it tended to come back.
In 592 Japanese players aged 6 to 15, "School-aged basketball players had a point prevalence of 12.8% for LBP", and players with knee or ankle pain had more back pain; arm pain went with back pain too. Across 80 studies of adolescent athletes in all sports, 42% had low back pain over 12 months, and risk factors included "sport volume/intensity" and "concurrent lower extremity pain". Back pain isn't growing pains: the NHS describes growing pains as aching or throbbing in both legs in the evening or at night.

A stress fracture of the spine (spondylolysis) in teenagersEmerging evidence
The American Academy of Orthopaedic Surgeons (AAOS) says "Spondylolysis is a weakness or stress fracture in one of the vertebrae", and "The pars interarticularis is the weakest portion of the vertebra"; it comes from "repeated hyperextension and rotation" (arching and twisting). In a US children's sports clinic, "Forty-seven percent of the 100 adolescents were ultimately shown to have a spondylolysis stress fracture", against 5% of adults.
Basketball is named often in these studies: in 533 young patients at a US sports medicine practice, "Soccer, gymnastics/cheer, football, and basketball were the most common sports associated with spondylolysis", and it was one of the four sports most often named in a review of athletes' outcomes. These are clinic series, so they reflect who plays and who is referred, and they give no risk per player. A pooled analysis of basketball studies put spondylolysis at 14%, but with an interval from 0.1% to 27%, so that figure is very uncertain. Young athletes who played one sport had more stress injuries higher in the lower back (adjusted odds ratio 1.80), an association.

Discs, sciatica and serious injuries: uncommon to very rareEmerging evidence
"Disk herniation" was 2.9% of college players' low back injuries. Over 30 NBA seasons, 61 players had a lumbar disc herniation, about 2 a season across the league, and "Return-to-play (RTP) rates did not differ between NOT and OT players (77.8% vs. 79.4%)" (players treated without and with surgery).
Serious spinal cord injury in basketball is very rare. The US National Center for Catastrophic Sport Injury Research recorded 41 traumatic catastrophic injuries of any kind in high school and college basketball over 43 years, about one a year across both. A review says "basketball has the highest number of nontraumatic catastrophic injuries for female athletes", mostly heart-related, which is why the heart line is among the warning signs.

Who gets it, and the loadEmerging evidence
Back pain in athletes went with "A previous episode of LBP, high training volume, periods of load increase and years of exposure". In 49 youth players, "Injured youth basketball athletes had a low previous 3- and 4-week workloads coupled with a high previous 1-week workload" (leg injuries, not backs), and in college women, "Preseason-practice injury rates were more than twice as high as regular-season practice injury rates". Older recreational players are not well studied; the general back pain advice applies.

When a scan or test mattersStrong evidence
Most back pain after basketball 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 disc degeneration showed on scans of 37% of 20-year-olds without back pain. A pars defect is found in about 1 in 17 adults scanned for other reasons, "5.9% (males: 7.9%, females: 3.9%)", so a defect on a scan isn't always the cause of pain.
For a teenager whose back hurts arching backwards for weeks, a scan does change what happens: a review of imaging found "two-view plain films to be the best initial study" and advised that "MRI should be used in early diagnosis and CT in more persistent courses" (MRI is magnetic resonance imaging, CT computed tomography), and examination tests alone couldn't tell a stress fracture from other back pain. After a fall with pain in one spot over the spine, or with leg weakness or the cauda equina signs, imaging comes first.

How it usually goesEmerging evidence
Most aches settle within days; NHS inform says back problems "should begin to settle within 6 weeks". In college players, most were back within 24 hours of a low back injury, and all the women within 3 weeks; in the NBA, most missed 1 to 2 games. Back pain in young players tends to come back, so build back gradually.
For spondylolysis caught early, "In the very early stage, the bony healing rate was 100%, and average treatment period was 2.5 months" in a Japanese series, though "The average overall recurrence rate was 26.1%"; "The time to return to sports was 4.6 and 6.8 months for conservative and surgical approaches, respectively" across 14 studies; and in a trial, starting physiotherapy straight away brought players back at a median of 74 days against 112. Followed for 45 years, "Subjects with pars defects follow a clinical course similar to that of the general population". No one can promise a date.

When it isn't basketball: the causes the warning signs cover
Some back pain has causes basketball didn't create, and the warning signs follow the pages behind them. Numbness around the genitals or bottom, new bladder or bowel trouble or both legs weak can be cauda equina syndrome, a 999 call in the words of the NHS back pain and sciatica pages. After a hard fall or a direct blow to the back, NHS inform's back problems page asks for help from NHS 111 the same day.
After a fall onto the head or neck, or a collision, the neck lines follow NHS inform's neck injury page and NICE's spinal injury guideline, which lists the dangerous ways to hurt the neck, among them a fall from more than 1 metre or 5 steps. The UK grassroots concussion guidelines say someone with a suspected neck injury should be moved only by healthcare professionals with the right training.
The other warning signs follow the pages they were first written from. A burst abdominal aortic aneurysm (a swelling of the body's main artery) can cause sudden, severe tummy or back pain, a 999 call on the NHS aneurysm page; the NHS kidney infection, foot drop and septic arthritis pages, a Leicestershire NHS leg pain leaflet and NICE's guideline on cancer that has spread to the spine give the same-day signs. The Royal Osteoporosis Society, the AAOS, the UK osteoporosis guideline and NICE describe fractures from thin bones after a minor fall. A stress fracture of the spine in a young athlete is described in a long-term study that followed 500 children from age 6, and the NHS spondylolisthesis page says when lower back pain needs a GP. Two NHS children's physiotherapy services, in York and Scarborough and in Gwent, list when a child's back pain needs a GP. The NHS ankylosing spondylitis page and NICE's spondyloarthritis guideline describe back pain and stiffness that starts in the teens or young adulthood. The NHS chest pain and fainting pages give the 999 signs for chest pain or fainting on court.
