Aims: From 1990 until 2000 62 patients with S.u.F.E. were treated with the cologne treatment pattern (dynamic screw þxation on both sides with lateral growth reserve). We intended to investigate the medium-term subjective and objective results of this method in comparison to the usual form of treatment with osteosynthesis using Kirschner wires. Methods:The patients answered a questionnaire followed by a clinical and radiological examination. Results: 30 patients could be reexamined. We found 26 patients with good and very good results in the subjective evaluation. The lateral outclass caused only problems when the growth reserve was used up. The clinical investigation conþrmed the subjective results: Free range of motion in 25 children. The radiological examination showed normal formed femoral heads and CCD angels. Conclusion: We can show that this therapy pattern has very few complications in comparison with the with K-wires- þxation. In literature the motion of the wires and the possible infection of the soft tissue were often described. The dynamic- screw Ðsystem allows a very simple change of the screw, when the reserve of growth is used up.

Aim: Is there a need of reduction control with MRI after closed reduction of unstable hips in children with CDH ? Methods: So far 88 children with unstable hip joints received a hip plaster of paris after closed reduction. The x-ray examination of the hip was followed by an MRI of the presumed reduced hip. The MRI examination was performed under sedation of the children with choralhydrat. Results: Out of the 88 hip joints 6 were thought to be in right position after x-ray examination but the MRI showed an unsatisfactory reduction. After a second attempt to reduce the hip joint a follow-up MRI examination was performed showing thereafter a satisfactory position of the hip joint. Conclusions: Due to the high number of missed dislocated hip joints after attempted reduction and x-ray examination we beleave that an MRI of the hip joint is absolute necessary to recognize unsatisfactory reduced unstable hips.
