The care of children and adolescents differs significantly from that of adults. That is why our expert and private doctor, Dr. Leonhard Döderlein, devotes himself within the special paediatric orthopaedics both conservatively and surgically to various diseases that occur in childhood and adolescence.
During the growth phase, the bones are not yet fully grown and the posture in childhood and adolescence is not consolidated. It is therefore important that bone malpositions and postural deficits are detected early and treated in a specialised manner. It is important to us to prevent later damage to joints. For this reason, children with orthopaedic-surgical diseases also receive a specialized range of treatments at the Groß-Gerau district clinic.
Dr. Döderlein offers a special paediatric orthopaedic private consultation for children and adolescents with orthopaedic restrictions and diseases.
The service portfolio includes in particular:
- Orthopaedic examination and treatment of joints in the hip, knee and foot area
- Team-oriented treatment together with orthopaedic technology, physiotherapy and specialised care
- Specialized counseling and treatment of neurological conditions and diseases with corresponding malpositions in the skeletal system (cerebral palsy, spina bifida, arthrogryposis, neuropathies)
- Surgical treatment of hip, knee and foot deformities
- Treatment of paralysis-related malpositions on arm and hand
