This study was performed to investigate the range of motion and the forces on the facet joints that are neighboured to spondylodesis on thoracolumbar spine. We used a special spine testing device for a continuous application of pure moments in each direction. For measuring the ranges of motion we used a magnetic tracking device for measuring forces on facet joints we chose a direct measuring system of quartz crystal and prepared for investigation of the spine. ⋯ Our findings could be an indication for changing in joints loading. This could be an explanation for early degenerative changes in spinal segments adjacent to spondylodesis. The results confirm the demand of short segment instrumentation and early remove of implants to keep influence as low as possible.

Case Reports
[Supracondylar corrective osteotomy in post-traumatic cubitus varus. 3 cases in 2 patients].
Supracondylar fractures of the humerus in childhood frequently result in cubitus varus deformity. Pain, functional impairment and cosmetic problems can request surgical correction. ⋯ Planning, surgical technique and outcome of the osteotomies are described. We should recommend the resection of a full wedge with two oblique osteotomies and internal fixation with two plates on either side of the humerus.
