Almost every Brazilian jiu-jitsu practitioner has hurt a toe at some point, and almost everyone underestimates how serious it can be. Ten years of US emergency department data show that the toes are the single most frequently fractured site in BJJ, accounting for 14.15% of all fractures. More surprising still, each toe fails for a different reason, tied to a different technical situation and a different direction of force. This article works through them one at a time, drawing on 12 PubMed papers plus competition injury data.

Why are toe injuries so common in BJJ?
BJJ is trained barefoot. The external support a shoe provides is simply gone, and the toe joints can see loads of 200–300% of body weight during movement, rising to as much as 800% in jumping actions (Maffulli et al.). Training mats also have high surface friction, so a toe can catch and stick mid-technique, a risk that barely exists in shod sports.

Five toes, five different weak points
No study to date has classified BJJ injuries by individual toe number; the existing literature reports the foot and toes as a single region. The breakdown below combines BJJ biomechanics literature with orthopaedic clinical data to work through the toes one by one.
| Toe | Most common injury | Primary mechanism | Supporting literature |
|---|---|---|---|
| First toe (hallux) | Turf toe, MTP joint dislocation, stress fracture, sesamoid fracture | Planting the foot and driving forward; hallux dorsiflexion beyond physiological range | Scoggin 2014, Maffulli, StatPearls |
| Second toe | Jammed toe, plantar plate tear, proximal phalanx fracture | Lateral deviating force; load transfer caused by hallux valgus | McDonald 2017, Zanno 2023 |
| Third toe | Proximal phalanx fracture, ligament sprain | Transverse pulling force when the toe snags on a gi or mat edge | McDonald 2017 (inferred) |
| Fourth toe | Proximal phalanx fracture, ligament sprain | Similar to the third toe; compression from both sides | McDonald 2017 (inferred) |
| Fifth toe (little toe) | Direct impact fracture (proximal/distal phalanx), avulsion fracture | Exposed lateral border of the foot; stepping on a partner's heel or a mat edge | McDonald 2017, general orthopaedic literature |
First toe (hallux): the epicentre of BJJ toe injuries
1
Turf toe
Most common, Grade I–III
Ligament injury
- Sprain of the plantar capsuloligamentous complex
- Competition data: 2 of the 3 toe injuries in Scoggin 2014 were turf toe
- Grade I: 1–2 weeks; Grade III: up to 12 months
1
MTP / interphalangeal joint dislocation
Including irreducible cases
Dislocation
- A sesamoid trapped in the joint space blocks closed reduction, so surgery is needed
- Open dislocation: the hallux catches in a mat seam and the body rotates over it (Jones 2014, military combatives case series)
- Practical note: mats with fewer seams meaningfully reduce this injury
1
Proximal phalanx fracture / stress fracture
38–56% of all toe phalanx fractures
Fracture
Stress fracture
- The proximal phalanx of the hallux is the most frequently fractured toe bone segment
- Stress fractures: in a series of 26 hallux stress fractures, 22 (85%) occurred alongside hallux valgus deformity
1
Sesamoid fracture / sesamoiditis
Easily confused with a bipartite sesamoid
Sesamoid
- Tibial sesamoid fractures outnumber fibular ones
- Around 85% of people have a bipartite sesamoid (congenital split), so X-rays need careful reading
- Sustained standing guard positions such as spider guard aggravate chronic inflammation
First-toe mechanisms: nearly all involve planting the foot and driving forward
| BJJ technique | How force is applied | Main injury |
|---|---|---|
| Single-leg and double-leg takedowns | Foot planted, body driving forward, forcing the hallux MTP joint into dorsiflexion | Turf toe (Grade I–III) |
| Upa (bridge) escape from bottom | Bridging off the toes, with the hallux carrying full body weight | Turf toe, sesamoid fracture |
| Spider guard | Foot held continuously against the opponent's arm with the hallux in sustained dorsiflexion | Chronic MTP joint inflammation, stress fracture |
| Gi entanglement | The opponent's trouser leg or sleeve loops over the hallux and applies a valgus force | Medial collateral ligament tear, acute hallux valgus |
| Catching a mat seam | The hallux jams into the gap and the body keeps rotating | Open interphalangeal joint dislocation (case report) |
Important: the turf toe grade dictates your return to training
Grade I (ligament sprain): back to normal training in 1–2 weeks. Grade II (partial tear): 4–6 weeks. Grade III (complete tear with plantar plate rupture): up to 12 months post-surgery. Most practitioners treat turf toe as a minor knock and keep training, and repeated re-injury is the single biggest risk factor for hallux valgus and chronic instability.

Second toe: the innocent bystander of hallux injuries
The second toe is often injured not by direct force but by load transfer after the hallux stops doing its job.
2
Plantar plate tear
Plantar-side tear at the MTP joint
Ligament / plate injury
- Chronic wear or acute tearing of the plantar fibrocartilaginous plate at the second MTP joint
- Typical presentation: a "floating toe" and pain on pressing the sole
- Second-toe plantar plate tears are significantly more frequent in people with hallux valgus
2
Jammed toe / PIP dislocation
Jammed toe, PIP dislocation
Dislocation
Fracture
- McDonald 2017: 15 self-reported jammed toes and 13 hyperextended toes, most presumed to be the second through fourth toes
- Common when a toe stubs into the opponent's body during a takedown or while standing up
The second toe's special risk: the hallux valgus chain reaction
Chronic turf toe or hallux valgus reduces the push-off capacity of the big toe, and load automatically shifts to the second MTP joint during walking and training. Studies show pressure at MTP2 in mid-stance can rise by 40–60%, which over time produces chronic wear of the second-toe plantar plate and even second-toe stress fractures. Put simply: if you never fix the big toe, the second toe will eventually follow it down.

Third and fourth toes: casualties of gi entanglement
Data on third- and fourth-toe injuries is the scarcest in the BJJ literature, and cannot really be quantified separately from existing studies. Clinical observation and the "other toes" category in McDonald et al. 2017 suggest their injuries come mainly from transverse loading.
3
Proximal phalanx fracture / ligament sprain
Transverse pulling injury
Fracture
Sprain
- Mechanism: the toe catches in the opponent's gi while playing guard, creating a lateral deviating force
- The proximal phalanx is the longest segment, so it sees the largest bending moment and fractures most often
- Usually injured together with the fourth toe (and taped together as a pair)
4
Proximal phalanx fracture / ligament sprain
Same injury type as the third toe
Fracture
Sprain
- Same mechanism as the third toe: compression from both sides plus gi entanglement
- When framing against a passing opponent, the foot presses sideways into their arm and the outer third and fourth toes take the shear
- Also common as an impact fracture after stepping on a partner's instep during stand-up grappling
Fifth toe (little toe): the most exposed and most easily struck
The little toe sits on the outermost edge of the foot with no neighbouring toe to cushion it, making it the most frequent target of direct impact. Little-toe fractures are practically routine among BJJ practitioners, yet they are often ignored because the pain is usually mild.
5
Direct impact fracture
Proximal/distal phalanx, most common
Fracture
- Stepping on a partner's heel or a mat edge, or striking the floor during a fall
- Little-toe fractures are usually dismissed with "tape it and keep training", but poor healing can affect gait later on
5
Fifth metatarsal base fracture
Avulsion fracture / Jones fracture
Fracture
- Acute inversion of the foot makes the peroneus brevis tendon yank hard on the fifth metatarsal base, producing an avulsion fracture
- Jones fracture (proximal metaphyseal-diaphyseal junction): poor blood supply, difficult healing, 6–20 weeks, often surgical
- Football accounts for 38.7% of fifth metatarsal fractures; BJJ has no separate figure, but the stand-up and falling mechanisms are comparable
5
Lateral loading while playing guard
De La Riva guard is high risk
Sprain
- De La Riva guard: the hooking foot rotates outward against the opponent's leg, loading the little toe in inversion
- Defending a torreando pass with lateral steps exposes the little toe first to being trodden on
Jones fracture vs. avulsion fracture: one word apart, worlds apart
Both sit on the fifth metatarsal, about 1 cm from each other. An avulsion fracture (at the proximal tuberosity) is usually managed conservatively and heals in 4–6 weeks; a Jones fracture (slightly more distal, at the metaphyseal junction) has such a poor blood supply that failed conservative treatment means internal fixation surgery, and competitive athletes often go straight to surgery to shorten their layoff. The early symptoms look alike, so always confirm the location on X-ray.

Technique × toe risk cross-reference
In the competition injury records of Scoggin et al. 2014, every toe injury occurred in the same movement pattern: planting the foot and driving forward. How force is applied in a given technique directly determines which toe pays for it.
| Technique | Biomechanical mechanism | High-risk toe |
|---|---|---|
| Single/double leg takedown | Foot planted, full body weight driving forward, forcing the hallux MTP joint into dorsiflexion | First toe (turf toe) |
| Sprawl | Fast backward kick onto the toes, loading the hallux and second toe in dorsiflexion together | First and second toes |
| Defending a standing torreando pass | Wide lateral steps expose the outer toes to being trodden on or hitting an edge | Fifth toe |
| Spider guard | Foot pressed continuously into the arm, holding the hallux in prolonged dorsiflexion | First toe (chronic) |
| De La Riva guard | The hooking foot rotates outward, loading the little toe in eversion stress | Fifth toe |
| Upa bridge escape | Bridging off the toes with the hallux loaded in dorsiflexion | First toe |
| Stand-up grappling / falls | Acute inversion or eversion of the foot loads the fifth metatarsal | Fifth toe (metatarsal base fracture) |
| Gi entanglement (playing gi guard) | Trouser legs or sleeves loop over individual toes and create transverse pull | First toe (valgus), second to fourth toes (lateral) |
| Catching a mat seam | The toe jams into the gap while the body keeps rotating | First toe (open dislocation, case report) |
Gi vs. No-Gi: different injury patterns
Hinz et al. 2021 (1,140 athletes) found that practitioners who spend more than 50% of their training on No-Gi have significantly more ankle injuries than mainly Gi practitioners. Conversely, the fabric entanglement unique to Gi training raises the chance of an individual toe being caught, and is one of the main risk factors for hallux valgus and for lateral fractures of the second through fourth toes.
| Training type | Higher-risk injuries | Why |
|---|---|---|
| Gi | Hallux valgus, transverse fractures of the second to fourth toes, gi-entanglement toe injuries | Fabric can trap an individual toe and apply transverse force |
| No-Gi | Ankle sprains, injuries from lower-limb submissions (ankle locks) | No fabric to cushion, so the ankle takes submission force directly |
Competition data: IBJJF / ASJJF
The IBJJF has never published an official injury statistics report. The competition data that exists comes from independent academic research:
- Scoggin et al. 2014 (ASJJF Hawaii championships): 46 injuries across 5,022 matches, 36 of them orthopaedic. Five foot/ankle/toe injuries, of which all 3 toe injuries involved the hallux MTP joint (2 turf toe, 1 MTP hyperflexion sprain), every one occurring while the athlete planted the foot and drove forward. Overall injury rate: 9.2 per 1,000 matches.
- McDonald et al. 2017 (IBJJF-affiliated academy survey): 166 academies, 52 foot/toe injuries, 19 of them with a medical record (7 fractures, 5 turf toe, 2 dislocations), and 87.5% occurring in training rather than competition.
- Hinz et al. 2021 (1,140 athletes, 62 countries): Toe holds caused 24 injuries, 10% of all submission-related injuries. Note that toe-hold injuries target the ankle ligaments, not the toe phalanges themselves.
- Andreato et al. 2019: 32.3% of 70 training practitioners (23 people) had suffered a toe injury, and 11.4% of 35 competitors (4 people) were injured in competition.
Prevention, toe by toe
Buddy taping principles
First-line management of a toe injury is almost always buddy taping: strapping the injured toe to a healthy neighbour to give lateral support while preserving flexion and extension. Note that taping is not the same as healing. Turf toe of Grade II or above needs an MTP motion-limiting plate as well; taping alone is not enough.

Note that taping is not the same as healing. Turf toe of Grade II or above needs an MTP motion-limiting plate as well; taping alone is not enough.
- First toe (turf toe / sesamoid): use sandals or training shoes with a stiff forefoot (a carbon fibre plate) for warm-ups; in training, run rigid tape from the tip of the toe back along the arch to limit MTP dorsiflexion; in the acute phase, ice and elevate, and do no push-off work for the first 24 hours.
- Second toe (plantar plate injury): treating the hallux properly is the fundamental way to prevent second-toe plantar plate damage; once a plantar plate tear is confirmed, the MTP joint must be immobilised (cast or rigid-soled shoe), and pushing off through the injury is strictly out.
- Third and fourth toes (gi-entanglement injuries): toe sleeves in training reduce direct snagging on the gi; after a fracture, buddy tape for 4–6 weeks, and confirm there is no rotational deformity in proximal phalanx fractures.
- Fifth toe (direct impact / metatarsal base): competitive athletes with a Jones fracture are generally advised to go straight to surgery; avulsion fractures are managed conservatively with a short leg cast or walking boot for 4–6 weeks; check ankle mobility before training De La Riva guard to avoid compensatory excessive ankle inversion.
- Environment: choose interlocking mats with few seams, or a seamless roll; the open dislocation case in Jones 2014 was caused by a mat seam. Inspect the mat surface regularly for lifted edges and wear.
When taping it and training on is not an option
| Symptom / situation | Possible diagnosis | Recommended action |
|---|---|---|
| Swollen hallux MTP joint that cannot dorsiflex normally | Turf toe Grade II–III | Orthopaedic or sports medicine assessment, MRI to check plantar plate integrity |
| An audible pop under load with an abnormal-looking joint | Dislocation (reducible or irreducible) | Emergency X-ray to check for associated fracture; never force a reduction yourself |
| Obvious angulation of the little toe after a proximal phalanx fracture | Fracture with rotational deformity | Orthopaedic consultation; closed reduction may be required |
| Lateral fifth metatarsal pain after an acute ankle inversion | Jones fracture vs. avulsion fracture | X-ray to confirm the location; a Jones fracture must not be left to drag on conservatively |
| Persistent localised hallux MTP pain with a shadow on X-ray | Sesamoid fracture vs. bipartite sesamoid | Bone scan or MRI to differentiate; do not rely on the X-ray alone |
| Floating second toe with marked pain on pressing the sole | Plantar plate tear | Ultrasound or MRI to confirm; needs immobilisation, not just taping |
Closing thoughts
Toe injuries in BJJ are both common and easy to overlook. On the available literature, each toe really does fail in its own distinct way: hallux injuries are almost all turf toe from planting and driving forward; the second toe is usually a downstream casualty of a failing big toe; the third and fourth toes take transverse fractures from gi entanglement; and the little toe, as the most exposed lateral structure, absorbs the most direct impact.
It is worth noting that 87.5% of toe injuries happen in everyday training rather than competition, which means managing training intensity, taping habits and mat quality matters more than anything you do in the run-up to an event. Toe injuries rarely force anyone out of a match on the spot, but the cost of ignoring them accumulates and tends to surface years later as hallux valgus deformity, chronic MTP instability, or a Jones fracture that will not unite.
