A meta-analysis of the literature on the issue of selective thoracic fusion for the King-Moe type II curve pattern in adolescent idiopathic scoliosis.
METHODS
Meta-analysis of available literature.


OBJECTIVE
To attempt to clarify the confusion existing about the "King II" idiopathic scoliosis curve pattern.


BACKGROUND
Since the 1983 publication by King et al, surgeons have been confused as to when to include or exclude the lumbar curve in double curve patterns.


METHODS
The available literature was reviewed for relevant publications, which contained specific data analysis. Publications without adequate follow-up were excluded as were "commentary" publications unsupported by research data.


RESULTS
This literature review confirms the original publication by King et al that properly identified King II curve pattern patients need selective thoracic fusion only. The fusion should end at the thoracolumbar junction.


CONCLUSIONS
Selective thoracic fusion is the procedure of choice for properly selected King II curves.
