Abstract

In scoliosis, a slanting pelvis position in the frontal plane may give rise to a mechanical link leading to inappropriate distribution of the gravity force on individual spinal components and, ultimately, to the development of a force rotating the vertebrae. The author analysed gravity-induced variations in load on the hip joint as a result of a slanting pelvis position. The resulting formulas indicate an uneven load on the hip joints associated with this pelvis position. Uneven bone load in the hip joints may lead to a difference in length increments between the lower limbs. A persistent pelvic slant causes changes in the distribution of the gravity force acting on individual spinal components. Pelvic slant is often the cause of lumbar scoliosis. The scoliosis, initially functional, may become structural due to the asymmetrical load on bones. It seems obvious that the main goal of corrective and compensatory management of pelvic slant should consist in exercises to strengthen the muscles responsible for pelvis position.
