The conservative orthopaedic treatment of hyperkyphosis is less classical than the scoliosis one, because Hyperkyphosis does not affect the respiratory function, and it is more difficult to define normality. The consequences of hyperkyphosis are mainly pain and aesthetic. In English literature very few homogeneous series of results are published. Lowe  in a review of the current literature using evidence-based medicine, concludes that when recognized early in adolescence with progressive kyphosis, bracing treatment will usually result in modest correction of the deformity. Sachs  analyzing the results of 274 patients concludes that the Milwaukee brace is usually an effective method of treatment for patients who have Scheuermann kyphosis; however, four of fourteen patients who had an initial kyphosis of more than 74 degrees required a spinal fusion. Weiss  analyzes the use of transverse correction forces instead of distraction forces with a 3 points brace in 56 patients.In Lyon, we use since 60 years, an historical protocol consisting of: plaster cast reduction, plexidur 5 points brace and specific exercises. Currently, this treatment is performed in day hospital.
Material and methods
272 patients (142 boys and 130 girls) with an average age of 13 6 months were treated from 1987 to 2005 and reviewed 2 years after removal of the brace, even if the compliance of bracing was not good. The diagnosis was Scheuermann in 119 cases and idiopathic in 153 cases. We have 10 cases of Thoracolumbar pattern. Patients were evaluated either by clinical and radiological examination. Since 1998 an automatic update of a specific spreadsheet is performed by the secretary during the medical control. All data were analyzed by SPSS 18 IBM software.
The treatment should be initiated after the curvature exceeds 55 in a growing adolescent, especially for a boy with thoracic Scheuermann. Our results are worse for the thoracolumbar pattern which may predict chronic low back pain in adulthood with reduced quality of life of the patients and high costs with respect to medical care and occupational sickness leave. The treatment should be initiated after the thoracolumbar curvature exceeds 25°
Conservative treatment of hyperkyphosis in international literature is generally regarded as an effective treatment approach. Physiotherapy and bracing are the first-line treatments for this condition. The results of the Lyonaise management of kyphosis were very satisfactory in most patients.
