Patna: The All India Institute of Medical Sciences Patna has been recognised in the Limca Book of Records (2026 edition) following a rare and complex neurosurgical procedure involving the removal of a fish bone embedded deep within a patient’s cervical spine.
The operation, carried out on March 9, 2025 was led by Dr Saraj Kumar Singh with assistance from Dr Kranti Bhavana. Surgeons extracted a 35mm by 2mm fish bone from the neck of a 42-year-old patient, in what has been described as the longest foreign object removed from the human spine.
The procedure, conducted in the institute’s neurosurgical operating theatre, lasted just over four hours, beginning at 9am and concluding at 1.05pm. According to the hospital, the team navigated delicate spinal structures with high precision, successfully removing the object without causing damage to surrounding nerves or compromising spinal integrity.
Singh said operating so close to the spinal cord required exact execution at every stage. Bhavana credited teamwork and preparation for the outcome.
The institute’s executive director, Dr Raju Agarwal, described the achievement as a significant milestone, highlighting the hospital’s growing capabilities in advanced neurosurgery.
The case has been formally recorded in the 2026 edition of the Limca Book of Records, placing AIIMS Patna among institutions recognised for notable medical achievements in India.
