Preoperative and postoperative rotation profile in patients undergoing derotation osteotomies

Pt. no.	Segment	Preoperative Rt/Lt	Postoperative Rt/Lt
1	Femur Rt + Lt	FPA = −40/−40, IR = 80/80, ER = 20/20	FPA = 0/0, IR = 45/45, ER = 45/45
2	Femur Rt + Lt	FPA = −30/−30, IR = 85/85, ER = 30/30	FPA = 0/0, IR = 45/45, ER = 60/60
3	Tibia Rt/Lt	FPA = −40/−40, TFA = −40/−40	FPA = 0/0, TFA = 0/0
4	Tibia Rt/Lt	FPA = −40/−40, TFA = −45/−45	FPA = 0/0, TFA = 0/0
7	Femur Lt	FPA = −40/−40, IR = 90/80, ER = 30/45	FPA = 0/0, IR = 45/45, ER = 45/70

FPA: foot progression angle; TFA: thigh–foot angle; IR: internal rotation; ER: external rotation
