Für Kassen- und Privatpatienten

“For us, medical services, personal support and our patients’ quality of life are directly interlinked. Healing is a complex process, and we support it holistically: medically, personally and physically.”

Dr. med. Marcus R. Raum
Head of the Centre for Orthopaedics and Surgery on the Rhine (OCZ am Rhein)

We want people to be truly healed

The OCZ was founded to offer patients a kind of medical care that is seldom found even in large specialist or university hospitals. Being a practice, independent clinic allows us to carry out a thorough anamnesis and devote a lot of time to the right treatment. Our aim is to help people become mobile and pain-free once again – and, to do that, you have to want to truly heal them.

In many areas of the healthcare sector, the obligation to heal can only be fulfilled with difficulty, because medical staff lack the time and tranquillity to deal intensively with their patients. In the OCZ, by contrast, the patient is the central focus of all thoughts and actions. Healing them takes top priority.

Right from their first appointment with us, our patients receive our undivided attention, and when they arrive, they get an entirely thorough examination – in some cases, for the first time in their lives. Following this, we support them with personal medical care, keeping our attention always focused on the holistic picture. We can make sound decisions about treatments, and compare our decisions with the results.


Founder and Head of Clinic Dr Marcus Raum is a committed doctor and, right up to today, continues to work as an emergency service volunteer – because he believes that every doctor must be able to save lives themselves. The desire to help people has repeatedly driven him to seek out better and more effective forms of therapy. With his early-activating approach, he has broken new ground in the field of accidents and sports injuries.

As Chief Physician Emeritus, specialist for surgery, trauma surgery and special trauma surgery, he can point to a long university career and a multitude of publications. With his specialisation in endoprosthetics, particularly in the field of the upper extremities (shoulder, elbow), he is active in an extremely demanding and comparatively rare discipline. Another special feature of the OCZ is its follow-up care for injuries and surgical wounds.

In all of this, the medical services are inextricably linked to the personal, human connections between doctor and patient, and embedded in a context that exudes calm, friendliness and attentiveness. That’s because healing is always a matter of the soul as well.

Medical specialist for surgery and trauma surgery, special trauma surgery

Dr Marcus Raum was born in Cologne in 1967. Following his medical studies in Cologne, he completed a period of practical training in surgery at the St. Vinzenz Hospital in Nippes, Cologne. Between 1996 and 2004, he completed a course of study as a surgeon and trauma surgeon at the Second Chair for Surgery of the University of Cologne, where he was also active as an emergency doctor and helicopter emergency doctor. From 2004 to 2011, Dr Raum worked as Assistant Medical Director and later Medical Director (Chef de Clinique) at the Chair for Surgery at Groningen University Hospital in the Netherlands. From here, he returned to the Department for Orthopaedics and Accident Surgery at the Helios Clinic in Seigburg, where he was Chief Physician.

After a further period of activity as Chief Physician at the St. Joseph Hospital in Adenau, in 2020 Dr Raum opened OCZ am Rhein in Bonn, which regards itself as a practice clinic for orthopaedics and surgery. After his many years of experience in trauma surgery – particularly in the treatment of bone, joint and tendon injuries – Dr Raum is now an internationally recognised expert for arthroscopic and shoulder surgery. Another major focus of his work is on sports traumatology. He had already been running a surgery for sportspeople in Merheim. In Groningen, he worked as a surgeon and attending physician at the sports clinic of the university hospital. There, he built up a close collaborative relationship with the physiotherapists, something that is still a significant characteristic of his therapeutic concept for sports injuries even today.
