Card
Prof. Dr Sébastien Hagmann is a specialist in orthopedics and trauma surgery, with a focus on orthopedics and pediatric orthopedics, he is also a certified foot surgeon (GFFC) at the Deutsches Gelenkzentrum at the ATOS Klinik in Heidelberg, where he works as a specialist in foot surgery.
As anatomical masterpieces with highly complex structures, the foot and ankle joints literally carry us through life and are exposed to immense strain. This can lead to damage, which is exacerbated by injuries, incorrect footwear, obesity, or congenital deformities. Prof. Dr Sébastien Hagmann uses his expertise in treating these injuries to accompany his patients personally, confidently, and always open to all questions and concerns, from the initial consultation to possible surgery and follow-up treatment. State-of-the-art diagnostic equipment and surgery rooms, as well as wards offering the highest level of comfort, contribute to the highest level of recovery.
Heidelberg Foot Surgery – Comprehensive Expertise in Foot and Ankle Disorders
The human foot is a highly complex system consisting of numerous bones, withstand significant forces every day. Even minor changes in posture or movement can cause pain and significantly impair walking. Prof. Dr Sébastien Hagmann offers specialized foot surgery at the ATOS Klinik in Heidelberg for a wide range of diseases and deformities of the foot and ankle joint.
The focus is on a precise analysis of the causes, using modern imaging techniques alongside clinical examination. On this basis, Prof. Hagmann develops individual treatment concepts that are consistently oriented toward the function of the entire foot. Surgical interventions are recommended only if conservative measures are insufficient or no lasting improvement can be expected.
Special attention is paid to tissue-preserving, precise surgical techniques that maintain natural structures as much as possible and support faster rehabilitation.
The ATOS Klinik Heidelberg offers optimal conditions for this with highly specialized surgical facilities, short distances, and close supervision. The combination of specialized foot surgery, modern technology, and individually tailored follow-up treatment plans ensures a high level of treatment safety and long-term stable results.
Gentle Corrections for Claw Toes and Splayfoot
Claw toes and splayfoot are often caused by an imbalance in the muscles and tendons in the forefoot, or by chronic incorrect weight distribution. Patients often complain about pain when rolling their feet, at pressure points, or when footwear becomes more restrictive. A precise analysis of toe position and weight distribution is crucial to correctly assess the extent of the deformity.
Prof. Dr Sébastien Hagmann carefully assesses whether non-surgical measures are sufficient or surgical correction is advisable. Surgery aims to restore the toes to a functionally favorable position and, in the long term, improve pressure distribution in the forefoot. The focus is not only on external correction but, above all, on restoring pain-free, stable foot function.
Midfoot Surgery for Arthrosis, Deformities, and Overuse
Midfoot disorders can significantly impair the stability of the entire foot. Deformities or arthritic changes often lead to chronic pain, swelling, and an unsteady gait. The causes range from long-term incorrect weight bearing to the consequences of injury or degenerative processes.
Prof. Hagmann attaches great importance to differentiated diagnostics to precisely identify the affected joints at the Deutsches Gelenkzentrum Heidelberg at the ATOS Klinik in Heidelberg. Surgical measures aim to reduce painful movements, stabilize unstable joint sections, and functionally correct the shape of the foot.
Depending on the individual findings, joint-preserving procedures, osteotomies, or joint-stiffening procedures (arthrodesis) are used, which can often be performed using minimally invasive techniques in modern foot surgery. The aim is to achieve reliable pain reduction while maintaining as natural a level of mobility as possible in everyday life.
State-of-the-Art Rear Foot Surgery for Valgus Foot and Flat Foot
Deformities of the rear foot, such as valgus foot or flat foot, affect the entire leg axis and can cause discomfort extending to the knees or back. Structural changes in the bones and overloading of tendons and ligaments often cause these.
Prof. Dr Sébastien Hagmann comprehensively analyzes the individual foot statics to determine the type and extent of the deformity precisely. Surgical corrections aim to restore the anatomical alignment of the rear foot and improve the stability of the ankle joint. This reduces pain and ensures long-term walking ability.
Specialist in Complex Combined Foot Surgery
Complex foot deformities often involve multiple areas at once and require a holistic surgical approach. Prof. Dr Sébastien Hagmann has particular experience in treating such combined deformities, which require the rearfoot, midfoot, and forefoot to be considered together.
The basis for this is a precise analysis of the entire foot statics and individual movement sequences. The surgical strategy combines targeted bone corrections with stabilizing measures to eliminate incorrect weight distribution permanently. The aim is to achieve a functionally balanced foot shape that reduces pain and enables safe weight-bearing in everyday life.
Years of Experience in Corrective Foot Surgery
Corrective foot surgery requires a high level of experience, as even small changes can have a major impact on gait and weight distribution. Prof. Dr Sébastien Hagmann has been treating complex deformities for many years, including congenital and acquired changes resulting from injuries or previous surgeries.
A central aspect of the treatment is a detailed biomechanical analysis of the individual. Based on this, a customized surgical plan is developed that combines bone adjustments, tendon corrections, and stabilizing measures in a meaningful way.
Prof. Hagmann also offers a particularly high level of expertise in revision surgery - for example, for pseudarthrosis, residual deformities, or persistent instability.
In addition to surgical precision, structured follow-up treatment plays a crucial role in achieving lasting stability, pain-free function, and stable foot function.
