Prof. Dr. Metin Kucukkaya

Metin Kucukkaya was born in 1969. After graduating from the medical faculty in 1992, he began to show an interest toward lengthening and deformity surgery in adults and children. Over the next fifteen years he continued to focus intensively on classical Ilizarov surgeries including complex foot deformities, as well as a special cable bone transport technique and retrograde lengthening over nail technique he later developed.

His special interests include Orthopedic Trauma and treatment of bone infections and mal-nonunions, limb length discrepancies, and congenital deformities involving lengthening nails, hexapod system, and deformity plates.

He also participates in various projects designed for the improvement of these devices, one of which is the Precice nail. He was involved with a team of surgeons headed by Dr. Stuart Green on developing the design for the PRECICE Nail (Ellipse Technologies), the first magnetically-driven lengthening nail, a process which started before 2010. The next year, on June 8, 2011, he did the first human implantation in the world (see Handan Karamanlı). A few months later in December of the same year, it was used for the first time in the United States. Since this first surgery, the use of lengthening nails in lengthening surgery has spread quickly.

He has always been involved with a number of past and present projects related to emerging technology in the area of lengthening and deformity correction. The most recent one is with SYNOSTE, a company which does research and development related to lengthening nail technology.

He was appointed as Professor in Istanbul Bilim University's Department of Orthopedics and Traumatology in 2009. He is currently part of "Ortopedist Istanbul", a group of Orthopedic surgeons working in the area of orthopedic trauma, arthroplasty, sports medicine, and the spine.
