Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical and radiologic outcome (fracture consolidation)	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).	12 months
Secondary	Analgesic reuirement	Analgesic requirement via Pain score (Visual Analog Scale, VAS, Range from 1 (no pain) to 10 (strongest pain)) (27) at every study visit (except visit 1: preop. assessment)	12 months
Secondary	ROM	Clinical reassessment at Routine follow-ups at every study visit; - An Arc >100° shows a good functional result, arc 50-100° is a fair (acceptable) result, arc <50° shows a poor (unsatisfactory) result, according to the Mayo elbow performance index (see appendix).	12 months
Secondary	Woundhealing	Clinical reassessment at Routine follow-ups at every study visit; - Classification in normal or delayed/impaired. Signs for im-pairment are local secretion, swelling, reddening or wound dehiscence.	12 months
Secondary	Clinical fracture consolidation after one year	Clinical reassessment at Routine follow-ups at every study visit; - Clinical signs for good consolidation are: no pain while palpating the fracture site.	12 months
