A new technic for segmental spinal osteosynthesis using the posterior approach.

The authors have designed a new method of instrumentation aimed at obtaining surgical fixation of the scoliotic curve without any postoperative external immobilisation. It is particularly strong and rigid and allows adequate reduction of the curve. This technique avoids the sublaminar space and thus prevents excessive blood loss and diminishes the danger of cord damage.

Application technique of Cotrel-Dubousset instrumentation for scoliosis deformities.

Used in over 600 cases, the posterior Cotrel-Dubousset spinal instrumentation device has become the device of choice. This technique allows the most effective correction for all kinds of spinal deformities. It requires lengthy preoperative planning and is a technically demanding surgical procedure; however, because of its versatility it can be adapted to most spinal deformities.

[CD-instrumentation in the treatment of spinal deformities].

The development of CD-instrumentation aimed at corset-free postoperative patient management. Special attention was paid to a three-dimensional correction of spine deformities. Basic principles and implants are presented.

New universal instrumentation in spinal surgery.

A new instrumentation for posterior spinal surgery consists of metallic rods carved with diamond-shaped asperities on which vertebral hooks or screws can be screwed in any position, level, or degree of rotation. The rods are interlocked by means of devices for transverse traction (DTTs), rectangular constructs with multiple vertebral grips, the stability of which allows suppression of any postoperative external support. Initially designed to treat scoliosis, this instrumentation design allows mobilization of the vertebrae located at the apex of the curve and obtains a three-dimensional correction.
