Using older and new concepts on aetiology a new brace technique with thoracolumbar lordotic intervention in adolescent scoliotic and kyphotic deformities was created. The technique with symmetrical forces in the sagittal plane only on the thoracolumbar joint and its effect on the formative function of the extending muscles is explained.

Revision of older knowledge on spinal deformities shows causing factors in all day life and the source of rotational forces in men in respiration. The role of lordosis as a causative factor can change towards a correcting force, supported by different studies. The thoracolumbar spine is the originating area of many deforming processes.

Unlabelled: : Thoracic hyperkyphosis is a frequent problem and can impact greatly on patient's quality of life during adolescence. This condition can be idiopathic or secondary to Scheuermann disease, a disease disturbing vertebral growth. To date, there is no sound scientific data available on the management of this condition.

Unclear etiology in scoliotic and kyphotic deformities of the spine is responsible for uncertainty in treatment options. Normal all-day factors can be of importance. Newly developed or revisited clinical examination of sitting and supine children and consequent testing of neuro-muscular tightness shows to be useful in understanding the different spinal deformations and postural problems during growth and point to neuromuscular tension in growth.

Study Design: A prospective radiographic study was conducted.

Objective: To support our hypothesis that correction of the scoliosis may benefit from a lordotic fulcrum force in the sagittal plane on the thoracolumbar spine.

Summary Of Background Data: Adolescent idiopathic scoliosis is an important spinal deformity.

Background Context: A pedicle subtraction osteotomy can be considered as part of the surgical treatment of a symptomatic sagittal imbalance. The literature on the use of this technique is limited and thus far not applied to a rigid thoracolumbar hyperkyphosis.

Purpose: To evaluate our preliminary results of a pedicle subtraction osteotomy as an adjunctive tool in the surgical treatment of thoracolumbar kyphotic deformities.

The authors retrospectively evaluated 30 patients with an anterior cervical interbody fusion for cervical spondylosis or disc herniation. Open box carbon fiber cages were used at 45 levels. The visual analogue scales (VAS), respectively for neck and for arm pain, and the neck disability index (NDI) improved significantly (p < 0.

Background Context: Pronounced kyphosis of the thoracolumbar junction is a common orthopedic problem in adolescents and may require prolonged bracing therapy or correction spondylodesis.

Purpose: To describe a case where a kyphotic deformity was related to gynecological instead of spine pathology.

Study Design: Case report.
