About us

The University Clinic for Orthopedic Surgery focuses on the prevention, diagnosis and treatment of diseases and injuries of the locomotor system.

Introduction of team members:

Prof. Klaus A. Siebenrock, Clinic Director and Chief Physician, Team Leader Hip and Pelvis
As Chief Physician, Prof. Siebenrock also heads the hip and pelvis team. His expertise is particularly valued in complex surgeries, whether it is a matter of preserving joints - or whether it is about artificial joints. He also has extensive experience in sports traumatology and revision surgery of hip prostheses. Thanks to his international network and his membership in several top-class professional societies, he always stays up to date.

Prof. Dr. Dr. Frank Klenke, Team Leader Knee, Head of the Sarcoma Center
Prof. Dr. Dr. Klenke, head of the nationally known Sarcoma Center and Team Leader Knee, has made a name for himself as a proven specialist in tumor orthopedics from precise diagnostics to sensitive aftercare. As a knee expert, he is just as adept at joint preservation as he is at prostheses. He also has an enormous reputation in research, for example with papers on bone healing. This is not the only reason why he is a welcome guest at symposia.

Associate Lecturer Dr. Christoph E. Albers, Co-Leader Spine
As Co-Leader Spine Associate Lecturer Dr. Albers is familiar with injuries, diseases and fractures of the entire spine. He has a particularly high level of expertise in pelvic ring injuries, degenerative diseases and all types of cancer. He also enjoys an excellent reputation in spinal fusion surgery and in intervertebral disc endoprosthetics. In addition, he has a lot of experience in interventional pain therapy.

Prof. Dr. Johannes D. Bastian, Head of Orthogeriatrics, Hip and Pelvis Team
Associate Lecturer Dr. Bastian is also part of the hip and pelvis team as Head of Orthogeriatrics. This makes him exactly the right specialist when it comes to maintaining the mobility of elderly patients - in which his experience in prosthetics also comes in handy. Geriatric traumatology is also one of his absolute specialties. Also worth mentioning: in 2018 he received the coveted "SWIF AWARD" for his commitment to further medical education.

Dr. Moritz C. Deml: Co-Leader Spine, Head of Pediatric Spine Surgery
Dr. Deml is Co-Leader of the Department of Spine at the University Hospital and also Head of Pediatric Spine Surgery. He has extensive experience in the treatment of scoliosis and kyphosis - including in children - and in the treatment of spinal tumors. Numerous additional qualifications distinguish him - and his high level of expertise in complex microsurgical, endoscopic and minimally invasive surgical techniques.

Prof. Fabian G. Krause, Team Leader Foot and Ankle
As Team Leader Foot and Ankle, Prof. Krause is familiar with all diseases and deformities of the foot, especially with hollow and flat feet and with osteoarthritis. His expertise is also in demand for questions regarding cartilage damage or ankle instability. Whether hammer toes or claw toes, hallux valgus or problems with the Achilles tendon - the specialist, who also belongs to many renowned professional societies, has a lot of experience.

Dr. Michael Schär, Team Leader Shoulder, Elbow and Sports Medicine
Dr. Schär, Team Leader Shoulder, Elbow and Sports Medicine, has specialised above all in joint osteoarthritis and artificial joints. Especially when people with prostheses have to fight infections, he is considered the ideal person to consult.

He also has impressive expertise in tumor surgery.

Dr. Johannes Weihs: Co-Leader Shoulder and Elbow
Dr. Weihs, Co-Leader of Shoulder, Elbow and Sports Medicine, specializes primarily in joint osteoarthritis in the shoulder and elbow. With his additional qualifications in sports medicine, manual therapy and manual medicine, he has a particularly high level of expertise when it comes to bicep problems, tears in the rotator cuff, tendon transfer or complex tumor surgery.
