Computer-assisted versus manual spine surgery: clinical report

Clinical evaluation of a computer-assisted spine surgery system is presented. 40 pedicle screws have been inserted in lumbar and thoracic vertebrae in different types of disorder including scoliosis, spondylolisthesis, and iatrogenic or degenerative instability. 20 screws were inserted with a computer-assisted system while 20 were inserted manually. Surgery was followed by post-operative X-ray and CT examination, on which measurements of screw position relative to pedicle could be done. Comparison between the two groups show that the computer-assisted technique is much more accurate and safe than manual insertion.

Cross-sections of the Shoulder and Arm

These cross-sections are arranged into four groups corresponding to the areas commonly used for external fixation.

Cross-sections of the Forearm

The eighth cross-sections of the forearm are arranged in four groups corresponding to areas commonly used for external fixation.

Cross-sections of the Leg

The 11 cross-sections are arranged into five groups corresponding to areas commonly used for external fixation.

Cross-sections of the Thigh

The 11 cross-sections are arranged in six groups corresponding to areas commonly used for external fixation.

Querschnitte der Schulter und des Oberarms

Die neun Querschnitte sind in vier Gruppen geordnet, die den zur externen Fixierung des Humerus in der Regel geeigneten Knochenabschnitten entsprechen.

Querschnitte des Unterschenkels

Die elf Querschnitte sind in funf Gruppen geordnet, die den zur externen Fixierung des Unterschenkels in der Regel geeigneten Knochenabschnitten entsprechen.

Querschnitte des Unterarms

Die acht Querschnitte sind in vier Gruppen geordnet, die den zur externen Fixierung der Unterarmknochen in der Regel geeigneten Knochenabschnitten entsprechen.

Präparation und Analyse der Querschnitte

Die Bestimmung der Hautzonen, die einen sicheren Zugang zur Transfixation des Knochens bieten, erfolgte an der Leiche eines Erwachsenen ohne Deformation oder Achsenfehlsteilung der Extremitaten.

Preparation and Analysis of the Cross-sections

An adult cadaver without limb deformity or rotational malalignment of the limbs was used in this study of cutaneous zones for transfixing external fixation. In preparing the cadaver, the following steps were taken
