Decalcified connectivity scores. Results presented as Mean ± SEM where the mean was compiled by averaging scores from the proximal, middle and distal slides; connectivity scores were on average higher in the +CTL group relative to all other experimental treatments and the -CTL, which, at four months, elicited a minimal level of osseous bridging; LIPUS treatment appeared to improved osseous bridging and the degree of ossified tissue in the callus; a similar observation was made with the LAP treatment, though the degree of ossified tissue within the callus was smaller; combination treatment seemed to improve direct healing relative to all other treatment groups excluding the +CTL; LEGEND: H = host; A = allo/autograft. All statistical comparisons relative to the -CTL were not significant (p > 0.05).
