Willian “Kabuto” Masuda Returns Home After Paralysis from Banned Jiu-Jitsu Move

Willian “Kabuto” Masuda, a jiu-jitsu black belt, has returned home for domiciliary hospitalization after suffering a severe cervical spine injury that caused loss of movement and sensation from the chest down. Masuda was injured in August during a tournament in Londrina, Paraná, after being subjected to a “bate-estaca” (piledriver) slam, a move strictly prohibited in the sport.

Masuda’s First Public Statement on Recovery

In a video posted to Instagram on September 28, Masuda spoke publicly for the first time since the accident. He confirmed he is now receiving medical care at home and is taking necessary medications under professional supervision. Masuda requested patience and privacy from the public, stating that he needs time in isolation to process the trauma and focus on his mental health.

“I’m already home… I’m doing home hospitalization, in which I still need to take some medications,” Masuda said in the video. He noted that while he is not yet doing well psychologically, the prayers and messages of support have helped strengthen his heart and mind.

The “Bate-Estaca” Move and Medical Intervention

The injury occurred during a match against Juliano Di Pelli Machado. According to reports from SBT News and SCC10, Machado lifted Masuda while he was holding guard and slammed him head-first into the tatami. This specific maneuver, known as the “bate-estaca,” is banned in jiu-jitsu because the athlete being thrown cannot control their fall, exposing the cervical spine to extreme risk.

Emergency medical attention began immediately at the gymnasium. Following the initial stabilization, Masuda underwent a critical surgery the next day. While one source reports the procedure lasted nearly 10 hours, SBT News reports the surgery lasted nearly 12 hours. The operation was required to treat a high cervical spine fracture.

Criminal Investigation and Legal Stakes

The incident has triggered a legal investigation. Renato Castro, a public prosecutor and jiu-jitsu black belt who witnessed the fight, has formalized a “notícia-crime” (criminal complaint). Castro asserts that the athlete who applied the move could have foreseen the risk of a grave injury.

Police are currently investigating the circumstances of the match to determine if a crime was committed. In response to the allegations, Juliano Machado told reporters that he is praying for Masuda’s recovery and stated that he would never intentionally hurt anyone.

Future Outlook for the Athlete

The long-term impact on Masuda’s career remains uncertain. However, SBT News reports that Masuda’s father expressed a hope that his son could eventually return to the sport in a teaching capacity, as Masuda has a strong passion for instructing others, including children.
