Etiology of the so-called "idiopathic scoliosis". Biomechanical explanation of spine deformity. Two groups of development of scoliosis. New rehabilitation treatment; possibility of prophylactics.

INTRODUCTION Between various etiological factors of idiopathic scoliosis we also studied the biomechanical causes connected with the hip and pelvic regions. At all children with idiopathic scoliosis there is a real or functional abduction contracture of the right hip (sometimes plus flexions- and out-rotation contracture). The right hip abduction contracture is connected with "syndrome of contractures" at newborns and babies. MATERIAL 629 children treated in University Pediatric Orthopaedic Department, Lublin/Poland were divided into two groups: *I group of development of scoliosis- 220 children aged from 4 to 10. Real abduction contracture of the right hip 4-6-8 degree, adduction of the left hip 35-40-45 degree. Rotation deformity, both scoliosis (Lumbar L and thoracic Th) at the same time. Progression. **II group of development of scoliosis - 409 children aged from 10-12 to 14. Adduction of the right hip 10-15 even 20 degrees, adduction of the left hip 35-40-45 degree. Lumbar left convex scoliosis, no rotation deformity or small, no thoracic scoliosis, or small, no progression or small. INFORMATION ABOUT "SYNDROME OF CONTRACTURES": Clinical symptoms of _syndrome of contractures" were described exactly by Mau and others. At scoliotic patients we see in the region of right hip the following tissues contracted and shortened: *tractus iliotibialis, *fascia lata, * fascias of m.gluteus medius and minimus, *m. sartorius, *m. rectus, *capsules of right hip joint. CLINICAL RESEARCH: Since 1980s we added the tests for the adduction of both hips in straight position of the joint to the standard examination of scoliotic patient. Depending on the value of adduction movements of both hips we divided all patients into two above mentioned groups (I and II). EVALUATION OF PRESENT REHABILITATION TREATMENT IN OUR MATERIAL:Children were divided into three groups depending on range of scoliosis: A. Scoliosis L 5 degrees - 10 degrees, Th 5 degrees - 10 degrees. These children did not perform (wrong! ) extension exercises 10% B. Scoliosis L 15 degrees - 25 degrees, Th 15 degrees - 25 degrees. These children performed (wrong! ) extension exercises 30% C. Scoliosis L 25 degrees - 35 degrees or more, Th 25 degrees - 35 degrees or more. Older children. Extension (wrong! ) exercises long time (1-2-3 years! ) 60% CONCLUSIONS 1 . The so-called idiopathic scoliosis are connected with the right hip real or functional abduction contracture (sometimes plus flexion and out-rotation contracture). 2. There are two groups of development of idiopathic scoliosis. The first group - small children, early rotation deformity, both scoliosis (L and Th), progression. The second group is connected only with the habit of permanent standing "at ease" on the right leg. Older children. L scoliosis, sometimes Th scoliosis. 3. X-ray pictures of spine with pelvis are necessary for proper diagnosis.4. Abduction contracture of the right hip is connected with "syndrome of contractures" of new-borns and babies.5. We see necessity to introduce new stretching-flexion asymmetric exercises and a special sports program for the children endangered with scoliosis. 6. We proved that the "new prophylactics" through "new clinical test" and "new rehabilitation treatment" at school children (5-6-7-8 years old) gives positives results.
