研究概览
简要总结
The overall objective of the study is to describe the outcomes of osteosyn-thesis with magnesium based screws in children with a primary or second-ary (within 7 days from trauma) dislocated fracture of the Epicondyles ul-naris or Condylus radialis, and to compare them with outcomes of conven-tional osteosynthesis using steel screws.
If our results suggest non-inferiority of osteosynthesis with magnesium-based screws, the procedure could be tested formally in a subsequent full-size study.

结局指标
主要结局
Clinical and radiologic outcome (fracture consolidation)
时间窗: 12 months
radiologic outcome after osteosynthesis with magnesium based screws in children with a primary or secondary (within 7 days from trauma) dislocated fracture of the Epicondyles ulnaris or Condylus radialis Fracture alignment is measured as dislocation distance (mm). Appropriate alignement is a postopera-tive dehiscence or dislocation of less than 5 mm in Epicondylus ulnaris fractures and less than 2 mm in Condylus radialis fractures, according to literature (26/27/31).
次要结局
- ROM(12 months)
- Woundhealing(12 months)
- Clinical fracture consolidation after one year(12 months)
- Analgesic reuirement(12 months)
