“…Therefore, additional case reports on these presentations need to be published to increase awareness and determine the cause of these symptoms. Furthermore, these symptoms are especially rare in men aged < 60 years, as reported in this case[ 4 ]; recently reported cases of SM-NA have mainly involved young women after cesarean sections[ 8 , 11 ]. Therefore, we believe this case to be quite valuable.…”

“…Neurological complications, such as hematoma, infections, and temporary or permanent spinal cord injuries, can occur after spinal anesthesia[ 2 ]. However, involuntary myoclonic movement following neuraxial anesthesia is an extremely rare complication[ 3 , 4 ]. Sudden shock-like involuntary muscle contractions that affect a single muscle or multiple muscle groups[ 5 - 7 ] can occur following spinal anesthesia; alternatively, these movements can mimic a pedaling movement[ 8 ].…”

“…These symptoms rarely appear in the upper extremities[ 9 , 10 ]. Although there is no official name for this involuntary myoclonic movement, when it follows neuraxial anesthesia, it is called spinal myoclonus following neuraxial anesthesia (SM-NA)[ 4 ]. The characteristics of SM-NA are different from those of typical myoclonus, and the etiology is unclear[ 4 ].…”

BACKGROUND Spinal anesthesia is commonly used for various surgeries. While many complications occur after induction of spinal anesthesia, involuntary movement is an extremely rare complication. CASE SUMMARY Herein, we report the case of a 54-year-old healthy male patient who experienced involuntary movements after intrathecal injection of local anesthetics. This patient had undergone metal implant removal surgery in both the lower extremities; 7 h after intrathecal hyperbaric bupivacaine administration, involuntary raising of the left leg began to occur every 2 min. When the movement disorder appeared, the patient was conscious and cooperative. No other specific symptoms were noted in the physical examination conducted immediately after the involuntary leg raising started; moreover, the patient's motor and sensory assessments were normal. The symptom gradually subsided. Twelve hours after the symptom first occurred, its frequency decreased to approximately once every three hours. Two days postoperatively, the symptoms had completely disappeared without intervention. CONCLUSION Anesthesiologists should be aware that movement disorders can occur after spinal anesthesia and be able to identify the cause, such as electrolyte imbalance or epilepsy, since immediate action may be required for treatment. Furthermore, it is crucial to know that involuntary movement that develop following spinal anesthesia is mostly self-limiting and may not require additional costly examinations.

Myoclonus is defined as involuntary muscle contractions that are self-limiting. The presentation can be diverse, and severe movements may cause significant alarm to both patient and practitioner, with the potential for inappropriate management. Although rare, myoclonus has been associated with intrathecal anaesthetics; however, the exact aetiology remains unclear. In this report, we present a case of delayed spinal myoclonus following the administration of intrathecal bupivacaine to a patient with a known history of restless legs syndrome. The aim of this report is to increase awareness of this rare complication and to contribute to the current body of literature in order that the pathophysiology and potential risk factors may be better understood.
