My Name is Abdullah Abulaban I was born in 1988. I believe that orthopaedic surgery isn’t as algorithmic as other specialties. It does not have one single technique for every problem. It has a very big area that enables you to create new techniques. The orthopaedic field is artistic and I have witnessed the power of orthopaedic surgery, and I am willing to master this power to be an extraordinary orthopaedic surgeon to serve the humanity.

PD Dr. Philipp Ahrens was born in 1974. During his study program at the Technical University of Munich he was engaged with different prize winning medical developments.

Dr. Julian Fürmetz was born in 1978 and graduated from University of Leipzig in 2008. He started his training at the Department of Traumatology and Orthopaedics at the University Hospital of Leipzig. From early on, main field of interest was reconstructive surgery, and in 2014, he joined Dr. Thaller at the 3D-Surgery group in munich. Besides, he focused on various clinical areas such as spinal injuries, arthroscopic surgery, intra-articular fractures and more. In addition to the clinical work, he practised as a medical supervisor in professional soccer from 2013 to 2017.

Since 2016 he is head of the Department of Knee and Sports Traumatology at the Clinic for General, Trauma and Reconstructive Surgery at the University of Munich. In addition to all knee injuries, special interest and research focus are deformity correction around the knee joint, preoperative 3D analysis and planning, and mobility assessment post trauma.

Apart from surgery, Dr. Fürmetz likes to spend time with his family, friends and in the mountains.

Metin Küçükkaya 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 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.

Donghoon Lee is a director and founder of DALRI (Donghoon Advanced Lengthening Reconstruction Institute). He has been worked as a professor specializing in limb lengthening, deformity correction and reconstruction.

His special interests are limb lengthening for leg length discrepancy and cosmetic stature lengthening; any kinds of deformity including bowlegs, knockknees, rotational malalignment syndrome, genu recurvatum and complex deformities; recurrent (chronic) patella dislocation.

He is also developing 3D-pringting technology for minimal- invasive deformity correction.

Oğuz Poyanlı was born in 1966. He graduated from İstanbul University in 1990. He completed his residency at Göztepe Education and Training Hospital in 1995. He is still working at the same hospital as an Associate Professor in department of Orthopedics and Traumatology. He is interested in sports medicine and traumatology. He is a member of the education committee in TUSYAD (Turkish Sports Injuries Arthroscopy and Knee Surgery Association). Since 2006 he has been organizing arthroscopic motor skill learning courses .

Professor Qin Sihe has been engaged in orthopaedic surgery for over 40 years. As of December 30, 2018, he has presided over 35,075 cases of limb deformity and disability surgeries, including 23,520 cases of poliomyelitis sequelae. He is the surgeon with the most surgical treatment of PLsequelae in the world and has established the largest database of limb deformity and disability surgeries in China. He is also the first surgeon from the Chinese mainland who went to Russia to study and introduce Ilizarov technology, initiated the establishment of ASAMI China, and led the transformation of Ilizarov technology in China. For 40 years, Prof. Qin Sihe has been rooted in China. Based on China’s national conditions, in-depth study of Chinese culture, and information gathered from patients, he proposed the concept of Natural Reconstruction of orthopedics (limbs), established the lower limb orthopedics technology system with Chinese characteristics of Qin Sihe’s medical model and surgical style, and treated tens of thousands of cases of complicated limb deformities. In total, he has edited and published nine books on orthopaedic surgery in Chinese. In addition, his English book of Lower Limb Deformities Correction and Function Reconstruction, which he edited, will be published by Springer in the near future.

Sami Sökücü was born in1978. He graduated from  Istanbul University Cerrahpasa Medicine faculty in 2003, He finished his training in 2009 from Taksim Education and Training Hospital/Istanbul. He is still working Trauma and Deformity Department of Baltalimanı Bone Diseases and Training Hospital/Istanbul. He is interesting in Orthopaedic Trauma, treatment of bone defects, deformity correction, leg length discrepancies.

I am just a general orthopaedic surgeon, no single area of specialisation – trained in the States (Chicago), fellowships with Dror Paley (Baltimore – Ilizarov) and George Cierny (Atlanta – osteomyelitis) – live in Brisbane Australia now, past 15 years – I have been at this for 25 years – original training in Shoulder Surgery, early interest in Sports Medicine – after fellowships, interest and considerable expertise in the surgical treatment of osteomyelitis and musculoskeletal sepsis – further interest in deformity correction and limb lengthening, using both external fixation and IMN/ORIF – career evolved with extensive experience with complex revision total joints, particularly staged revision of infected total joints – my practice subsequently evolved further, and currently focuses on high energy trauma and intra-articular fractures, including pelvis and acetabular, proximal humerus, pilons, plateaus, calcaneus, and distal femur – considerable experience and expertise in post-traumatic limb salvage, both acute and chronic – for entertainment I enjoy percutaneous fixation of selected humeral shaft and calcaneus fractures – now also pursuing development of comprehensive approaches to osseointegration for the definitive reconstruction of amputees – current active research interests in trauma, intra-articular fractures, prosthetic joint infections, osteomyelitis, osseointegration, bibliometrics, 3D printing and modelling, stem cells, growth factors, biomechanics, robotics, genomics/biomarkers, deformity correction and more – current International President of ASAMI-BR, and also on the International Committee of the AAOS – over 100 publications, almost 2000 citations – for relaxation I play basketball and golf, and study astronomy and mathematics.

Peter Helmut Thaller was born in 1960. In 1991 he began specializing in traumatology and emergency medicine with special emphasis on limb lenghtening and reconstruction of bony defects, deformities and discrepancies (3D-Surgery) since 1997.

His special interests are the technical development of im-nails, devices for bone transport, navigation, augmented reality and digital analysis and planning for surgical procedures. Since 2003 he is lecturing and organizing courses for limb lengthening and deformity correction and supervising surgeries with various types of fully implantable lengthening nails in Europe and overseas. He was one of two founders and directors of the limb lenthening center munich in 2006.

Since 2009 he is head of the department for 3D-Surgery at the Clinical Center of the University of Munich.

Florian Wolf was born 1982. Yet as medical student, he was interested in 3D-Surgery and began assisting Dr. Thaller in surgical procedures, mainly the implantation of intramedullary lengthening devices. After his graduation 2009, he started his clinical career and specialization at the Department of General, Trauma-, Hand- and Plastic Surgery / University of Munich, where he joined the department for 3D-Surgery. His main interests are preoperative planning methods and specialized surgical techniques for lenghthening and deformity correction with intramedullary nails. For several times he also had the opportunity and pleasure to teach digital analysis and planning methods to a various number of international surgical guests of the department for 3D-Surgery.
