Twister Injuries in BJJ — Spinal and Rib Injuries from Eddie Bravo's Technique
The twister is a rotational spine submission popularised by Eddie Bravo's 10th Planet system that stretches the entire thoracolumbar spine into maximum rotation, making it a source of intercostal, lumbar, and thoracic injuries — particularly in athletes with pre-existing spinal sensitivity.

How the twister loads the spine and rib cage
The twister hooks the opponent's legs with a configuration similar to a body triangle, then uses both arms to pull the upper body in the opposite rotational direction to the lower body. This creates maximal thoracolumbar rotation — the spine is taken through its full rotational range under load. The primary soft tissue resistors are the thoracolumbar fascia, the erector spinae group, and the deep spinal rotators: multifidus and rotatores. These muscles work eccentrically to resist the forced rotation, and when the load exceeds their capacity, they strain.
The rib cage is simultaneously placed under torsional stress. On the convex (stretched) side of the rotation, the intercostal muscles are tensioned; on the concave (compressed) side, they are loaded in compression. This bilateral intercostal stress — tension on one side, compression on the other — is what makes the twister's rib involvement different from a direct compression injury like knee on belly. Athletes with pre-existing disc disease, osteophytes, or canal narrowing are at elevated risk of herniation because the technique combines axial load with rotation, the loading pattern with the highest disc injury potential.
Injuries from the twister — strain to disc herniation
Intercostal muscle strain from the twister presents as unilateral thoracic pain — typically worse on the convex (tensioned) side — with pain aggravated by breathing, coughing, and trunk rotation. Muscular tenderness between the ribs rather than on the rib bone distinguishes strain from fracture. Lumbar rotational strain presents as posterior lumbar pain worsened by rotation and side-bending, often with muscle spasm limiting movement. Thoracic facet irritation produces localised mid-back pain with a palpable tender point beside one spinous process, reproduced by extension and ipsilateral rotation.
In severe cases — particularly with high-force cranking or pre-existing disc pathology — lumbar disc herniation can result. This presents as posterior lumbar pain with radiating pain, numbness, or tingling travelling down one leg in a specific pattern corresponding to the affected nerve root (L4: medial leg; L5: dorsum of foot; S1: lateral foot and heel). Weakness of foot or ankle muscles may accompany the radicular pain. Any radicular symptom pattern after a twister warrants prompt physiotherapy or medical assessment rather than self-managed rest.
Twister safety considerations
The twister should be applied slowly and incrementally — there is a substantial range of safe spinal rotation before the technique loads the structures at risk. The finishing rotation is the dangerous phase; do not crank from the entry position directly to maximum rotation. Apply pressure, pause, and allow the defender to tap without rushing through the range. The technique's effectiveness in competition is precisely because it takes the spine to an extreme range; that same effectiveness makes controlled application essential in training.
Never apply the twister on an athlete who has disclosed pre-existing back problems. After a back injury from the twister: avoid lumbar rotational movements — including guard retention hip escapes, rolling drills, and berimbolo-style inversions — until acute pain fully resolves. A physiotherapy consult is appropriate if symptoms are not improving within 1–2 weeks, and mandatory if any leg pain, numbness, or weakness is present. Return to twister drilling should be progressive and only after complete resolution of all symptoms.

Frequently asked questions
Is the twister dangerous for the spine?
The twister carries higher spinal injury risk than most BJJ submissions because it applies maximal rotation across the full thoracolumbar spine simultaneously. For athletes with healthy spines it can be trained safely with gradual application and an early tap. For athletes with pre-existing disc disease, spondylolisthesis, or a history of back injury, the combination of axial load and rotation is a known aggravating mechanism and the technique should be discussed with a physiotherapist or sports physician before training.
Can the twister cause a disc herniation?
Yes, in athletes with pre-existing disc changes or with a high-force application. Lumbar disc herniation from the twister presents as posterior lumbar pain radiating into the buttock and down one leg in a dermatomal distribution (sciatica), often with associated weakness of specific lower leg muscle groups. The combination of axial compression and rotation is mechanically one of the most disc-sensitising loading patterns, which is why the twister is banned in many competition rulesets and should be applied with care in training.
How do I train the twister safely with a partner who has back problems?
The most important step is communication before drilling: ask about spinal history. Athletes with disc disease, herniation history, or active back pain should not be placed in the twister. When drilling with any partner, apply the technique slowly and incrementally — stop at the first sign of discomfort, not at the tap. Avoid cranking; the twister finish should be a controlled rotation, not a sudden rotational jerk.
How long does a lumbar strain from the twister take to heal?
An uncomplicated lumbar rotational strain typically resolves in 2–4 weeks with rest from rotational loading, progressive pain-free mobility restoration, and gradual return to loading. If pain persists beyond 2 weeks or includes radiating leg symptoms, physiotherapy assessment is appropriate to rule out disc involvement. Avoid lumbar rotational exercises and BJJ positions that require spinal rotation (guard work, hip escapes) until acute pain resolves.
