It is indicated in patients with symptomatic patella alta, i.e. patients with instability of the patella. It facilitates a V-shaped osteotomy. The bone gained during distalization is used as a proximal buttress. This leads to an improved mediolateral and proximal stability. The bony surface area is increased, which improves bony healing. There were no secondary dislocations in the patient group of 10 patients treated by the surgeon. The assessment of the cervico-thoracic junction in the neck CT is frequently hampered by streak artifacts from the shoulder girdles. To evaluate the effects of an optimized patient positioning through the use of an arm traction device. 25patients (age [mean ± standard deviation] 58.9 ± 11.6years; sex [mf]1510) underwent a neck CT using an arm traction device together. Further 25patients underwent this in standard positioning (59.8 ± 15.2years;169). An experienced neuroradiologist determined the last free accessible vertebra on the CT scout view and assessed the image quality of the intervertebral disc space of the lower neck on athree-point grading scale. The procedure was evaluated by the medical-technical radiology assistants performing it. The last free accessible vertebra on CT scout was statistically significant one vertebra lower using an arm traction device, yielding on average the sixth cervical vertebra (p = 0.010). Subjective image quality increased in all evaluated intervertebral disc spaces (median and absolute frequencies [good/middle/bad]1.0 [53/21/8] vs.2.0 [41/30/24]), resulting in astatistically significant effect between the cervical vertebra6/7 (p = 0.0041). The traction device approach was rated to be suitable for daily routine in the categories of patient's cooperation (good), comprehensibility for the patient (84%) and management for the assistants (good).
