In all the years analyzed, syphilis was the most recurrent RIHL. NHS is a means of early diagnosis and intervention that must necessarily be performed in the first months of the child's life. This study aims to evaluate the relation between coracoclavicular resistance to failure and the distance between clavicular tunnels. The hypothesis is that a greater clavicular bone bridge between tunnels achieves a stronger coracoclavicular fixation. Descriptive Laboratory Study. Thirty-six (36) coracoclavicular models were constructed utilizing porcine metatarsals. Coracoclavicular stabilizations were performed using a subcoracoid loop fixation configuration through two clavicular tunnels, tied at the clavicle's superior cortex using a locking knot. Models were randomly assigned to 1 of 3 experimental groups of variable bone bridge length between clavicular tunnels 5mm, 10mm, and 15mm. Each group had 12 models. Fixation resistance was assessed through the ultimate failure point under an axial load to failure trial. Failure patterns were documented. A one-way ANOVA test was used, and a Tukey post hoc as needed (P<0.05). Mean strength per bone bridge length 5mm=312N (Range 182-442N); 10mm=430N (Range 368-595N); 15mm=595N (Range 441-978N). The 15mm group had a significantly higher ultimate failure point than the other two groups 5mm (P<0.001) and 10mm (P<0.001). All fixations systematically failed by a superior cortex clavicle fracture at the midpoint between tunnels. A direct relationship between bone bridge length and coracoclavicular resistance to failure was demonstrated, being the 15mm length a significantly higher strength construct in a tied loop model. A direct relationship between bone bridge length and coracoclavicular resistance to failure was demonstrated, being the 15 mm length a significantly higher stre
