INTRODUCTION There is a general consensus that unstable vertebral body fractures of the thoracolumbar junction with a B type fracture or a high load shear index need to be surgically stabilized, primarily by a dorsal approach. The authors believe that there are indications for an additional ventral spondylodesis in cases of reduction loss or a relevant intervertebral disc lesion in magnetic resonance imaging (MRI) 6 weeks after dorsal stabilization. However, in cases of unstable vertebral fractures it remains unclear if a delayed anterior spondylodesis will lead to unacceptable loss of initial reduction. MATERIAL AND METHODS A total of 59 patients were included in this study during 2013 and 2014. All patients suffered from a traumatic vertebral fracture of the thoracolumbar junction and were initially treated with a dorsal short segment stabilization. All vertebral body fractures had a load shear index of at least 5 or were B type fractures. An x-ray control was carried out after 2 and 6 weeks and MRI was additionally performed after 6 weeks. An additional ventral spondylodesis was recommended in patients showing a reduction loss of at least 5° and in patients with relevant intervertebral disc lesions. The extent of the reduction loss was analyzed. Other parameters of interest were the fracture level, fracture classification, patient age and surgical technique (e.g. implant, index screw, laminectomy and cement augmentation). RESULTS The patient collective consisted of 23 women and 36 men (average age 51 years ± 17 years). The mean reduction loss was 5.1° (± 5.2°) after a mean follow-up of 60 days (± 56 days). The reduction loss was significantly higher when polyaxial implants were used compared to monoaxial dorsal fixators (10.8° versus 4.0°, p

To examine the influence of different surface machining treatments of resorbable implants 3x5 mm cylinders of magnesium-calcium-alloys with plane, rough or sand blasted surface and different concentrations of calcium (0.4 %, 0.8 %, 1.2 % und 2.0 %) were implanted into the distal femur condylus of 18 New Zealand White Rabbits. They were placed into the spongy-cortical passage. During six weeks the animals were examined daily and x-rayed weekly. After euthanasia the bone was explanted and scanned in a microcomputed tomograph. The implants were well tolerated by the rabbits, neither lameness nor signs of pain occured. Wound healing was mostly without complications. Eight of 36 implants (22 %) showed dehiscence of suture within first ten days, whereby implants made of 1,2 % MgCa were mainly affected (six of 12 cases, 50 %). At the place of insertion all implants induced obvious callus genesis which could be seen in MgCa 1,2-cylinders with plane surface and MgCa 0,8-cylinders with rough and sand blasted surface the most. Influence of different calcium concentrations on degradation behaviour could not be discovered. They showed different stages of resorption. Concerning the different surface machining treatments sand blasted implants showed the highest degree of degradation which could be seen by the totally loss of structure in micro-computed examinations. These implants also showed in six of 36 cases a clinical occurrence of gas production. Rough implants showed an irregular degradation with high degree of resorption of some implants and signs of degradation only in the border area of others. Cylindricity maintained in plane implants. They showed loss of structure only in border areas.
