Prof. Dr. Hermawan N. Rasyid Develops a New Template Concept in Handling Chronic Bone Infection

[unpad.ac.id/29/4/2019] Bone infection (osteomyelitis) is one of icons in orthopedic and traumatology cases. This is because the case is very difficult to handle. It’s become a challenge for orthopedic and traumatology specialists to handle it.

Such is addressed by a professor from the Universitas Padjadjaran Faculty of Medicine Prof. Dr. Hermawan Nagar Rasyid, dr., Sp.OT(K), M.T(BME), Ph.D., FICS, when he was giving a scientific oration titled “A New Concept in Handling Chronic Bone Infection to Answer Orthopedic and Traumatology Problems in Indonesia” in the Inauguration Ceremony and Scientific Oration held in Grha Sanusi Harjadinata Unpad, Dipati Ukur street No. 35, Bandung, Monday (29/4).

Prof. Hermawan said, chronic bone infection is a bone infection that is chronic. In 1970, scientist Bucholz and Engelbrecht introduced the use of antibiotic mixture to the bone cement as a prophylactic act to the bone infection.

“Since then, various research has been done around the world, whether in vitro, in vivo, and clinical, to increase the use of antibiotic beads in solving the infection in musculoskeletal field,” spoke Prof. Hermawan.

He explained, optimal management of chronic infection often needs a combination between surgery and antibiotics. But, osteomyelitis is difficult to treat with conventional therapy. The incorrect use of antibiotics may have a toxic effect and cause various infections because of certain resistance to specific antibiotics.

“This causes an increase in cost and duration of patient care. The increase of treatment cost causes the people in the lower class to have difficulty getting modern treatment in the hospital,” he spoke.

In his research, Prof. Hermawan surveyed how orthopedic specialists make antibiotic beads for osteomyelitis cases. The result, every orthopedic specialist has a different shape and size of bead.

“The writer concluded that beads made manually has different shapes and sizes, has little porosity on its surface, has suboptimal ratio between volume and surface area, and a not uniform antibiotic content,” he explained.

From his research, Prof. Hermawan developed a new concept in making antibiotic beads in the form of beads template system which could be easily operated and could make beads of uniform shape and diameter. This template is expected to be used by orthopedic specialists in Indonesia.
