Abstract
STUDY DESIGN: Meta-analysis of available literature. OBJECTIVE: To attempt to clarify the confusion existing about the "King II" idiopathic scoliosis curve pattern. SUMMARY OF BACKGROUND DATA: 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. CONCLUSION: Selective thoracic fusion is the procedure of choice for properly selected King II curves.
