Title Long-Term Skeletal Stability Following BSSO Advancement is Similar for Titanium and Biodegradable Fixation Systems
Clinical Question Is there a difference in the long-term skeletal stability of a BSSO advancement stabilized with titanium or biodegradable fixation?
Clinical Bottom Line There was no significant difference in skeletal stability over a 2 year period for patients who had BSSO advancements using titanium or biodegradable fixation.

The Evidence
Validity: In this cohort study, 149 out of 230 patients completed the 2 year postoperative follow-up. After the exclusions, only 15 patients in the biodegradable group and 22 in the titanium group were analyzed. In the original study, there was only 65% followup that could introduce a degree of bias. Hence, this bias limit the validity of the result. Perspective: The original study was a randomized controlled trial but after further analysis, the study only looked at a selected subpopulation. More clinical trials are needed to further evaluate any statistical differences in long-term skeletal stability for patients who undergo BSSO advancement with titanium vs. biodegradable fixation systems.
Applicability Biodegradable fixation is a new rising technology and a viable option in the near future. The advantages of this new system are short-term stability, the intra-operative switches, the number of plates that required removal, and cost-effectiveness. Due to limited amount of information given, the study does not provide enough information to guide a definitive decision at this time.
