Theoretical significance and practical importance Currently there is no consensus regarding post-operative immobilization protocols, and little evidence is available regarding timeframe for early return to functional activities following DBTR. Existing evidence on functional outcomes post DBTR is of low quality with small sample sizes, and no known RCTs exist comparing early mobilization to immobilization on functional return. Reported timeframes for immobilization range from early controlled motion on day 1 post-operatively to complete immobilization for 6 weeks.
