This study aimed to determine whether there is an age below which flex
or tenolysis may not be beneficial and whether there is any detriment
to waiting for a more appropriate age. In this study, patients in thei
r first decade had minimal improvement in their active flexion after f
lexor tenolysis. Six patients were tenolysed more than 1 year after th
eir original operation and none appeared to have been compromised by t
he prolonged interval between injury repair and tenolysis. Significant
improvement in active flexion after tenolysis can be confidently expe
cted only in children over 11 years old.
