There are some rare souls who visit us in the timeline more ardently, lovingly, selflessly, and honestly to enlighten us and helping our search for the truth. They do not crave or expect anything from us in return, neither the publicity for their timeless work nor deeds they gifted to the society. Dr. Biswajit Sen was one among them and would be remembered till the word “innovation” and humility is there in the vocabulary.

Birth (1920) and schooling has got interesting anecdote. He was brought up at Sardar Shankar Road residence at Ballygunge, Calcutta (now Kolkata). His father was from Jashore, Bangladesh, then settled in Ballygunge, Calcutta. He was an MRCP, a renowned physician in those days.

Dr. Sen had his schooling at Mitra Institution at Mirzapur and had a brilliant carrier at Presidency College before doing MBBS (1948) at Medical College Hospital Calcutta. The legendary Prof. Subir Chatterjee (father of pediatric surgery in Asia) was his contemporary and classmate at MBBS.

Then he worked as the registrar under the great Panchanan Chatterjee at MCH. Then he went to IRWIN Hospital (today’s MAMC) Delhi to work for a couple of years. Dr. Sen left for England in 1956 and worked with renowned surgeons such as ARDEN and RJ. Salter. He completed FRCS in 1962–63. During his stay at England, he came across Dr. Ratna Sen, who was completing her FRCS then. Afterward, they acquainted and got happily married and settled.

Dr. Sen couple returned from England in 1963 to join at Ram Krishna Mission (RKM) Hospital as an orthopedic consultant to start the Orthopedic Department. His wife Dr. Ratna Sen joined at SSKM Hospital as pool officer, in plastic surgery.

How he developed the Orthopedics Department at RKM was a riddle? He faced a lot of difficulties to get good faculties in the 60s. Noted faculties, such as Dr. Subrata Dasgupta (FRCS), joined as pool officer (1965) then. Afterward, he left for CMRI (1968), Dr. N. De Mazumder joined as deputy (1968), Dr. Saurya Banerjee (FRCS) as pool officer (1971), Dr. Dibyendu Gope (FRCS) as pool officer (1972), Dr. Sukhendu Banerjee (MS, FRCS) as pool officer, Dr. Susanta Sarkar as first house surgeon, Dr. Arun Banerjee (FRCS) in 1975 as pool officer, Dr. R.N. Hom Choudhury (1975–76) as registrar, Dr. Tapas Chakraborty (1978), and others enriched the orthopedic department. Dr. Sen later earned a good name in the country and abroad. Dr. Sen always loved to inspire and encourage the subordinates and liked to see that they should prosper. Thus, all the faculties under his care made good name and success in their professional life.[1]

His innovative mind and honest approach to solve common orthopedic problems such as fracture neck of femur, rheumatoid arthritis (RA) and recurrent shoulder dislocation led him to develop goodwill, to bind the colleagues in the department and to inspire them to do new useful things. The one that of “Bengal Model” in CTEV by Dr. N. De Mazumder (1973) is the best example of it.[2] Once, Mr. ARDEN visited Calcutta and showed total hip replacement (THR) in 1976 at RKM. He had to face difficulty as had an early setting of his England’s Bone Cement here in the Tropics. Afterward, Dr. Biswajit Sen urged and persuaded Dr. N. De Mazumder to show his invented CTEV machine to them, when ARDEN’s colleague commented “it’s a little piece of ingenuity.”{Figure 1}

As for publication, he was shy in publication matters but very much enthusiastic in presenting papers/scientific works in ASI meetings in those days, from 1965 to 1982. He loved to visit with his colleagues and attend orthopedic chapter of ASI at various places such as Delhi, Nagpur, Allahabad, Nasik, and Madras (now Chennai) to present his original works and often being highly applauded. His memorable hip symposium was recorded in the Golden Jubilee Commemoration Book of RKM in 1982. He was the scientific secretary at that conference. The Annual Conference of Association of Surgeons of India was held in 1980 (ASICON – 1980) at the Ramakrishna Mission Institute of Culture at Golpark, Calcutta, where his classmate Prof. Subir Chatterjee was the organizing secretory. and he was the scientific secretory. Dr. Sen’s honesty and goodwill for colleagues made him respectful and trustworthy.[1]

 What Are the three Important Innovations?

Recurrent dislocation shoulder was a common problem. The bony defect was highlighted by the epoch-making discovery from long work on cadavers and Calcutta Museum by legendary Prof. AK Saha and was published in the Acta Orthopaedica Scandinavica (1967) and a book on Shoulder Mechanics (Stuttgart, Germany).[3],[4],[5] This inspired Dr. Sen to develop a simple osteotomy to correct the desired anti-tilt of the glenoid to prevent anterior dislocation. Dr. Sen and Dr. De Mazumder once showed the transaxillary approach for glenoidal osteotomy to correct anti-tilt at NRSMCH in the early 70s as per invitation by the great legend Prof. AK Saha. This was highly appreciated then.

For the unsolved # Neck Femur, his innovation of Sen’s Nail was revolutionary. The operation was almost bloodless in contrast to others available in those days. It gained much popularity not only because of its simplicity but also due to its short operation time. Dr. Tapas Chakraborty had his dissertation on this innovative procedure under Calcutta University.

Rheumatoid arthritis was a burning problem. Dr. Sen started doing thymectomy and had good initial results in chronic cases. He used to show earlier results of thymectomy in clinical meetings. Later he abandoned it due to unknown reasons. He had the skill to fuse C1–C2 by transoral approach also.

Dr. Sen was a researcher, innovator, and a courageous surgeon with honesty and confidence. He was a gentle, calm, good teacher, and used to encourage the youngsters to concentrate on work and try to avoid show business.

As for socialization, humility, and human values, he was very social and loved to attend social functions with his family including their small daughter Sipra.

An intense spiritual urge was noticed from the beginning. He used to visit his spiritual Guru at Bolpur. Until 1983, even in Alzheimer's state, he used to show his deep inclination toward divinity. Dr. Biswajit Sen breathed his last with complications from Alzheimer's in 1988 at the age of 68 only.

We lost an ardent researcher and an innovator who set an exemplary, honest, and respectful character before us for many years to come.
