Callus distraction is the standard procedure for the operative treatment of
leg length discrepancy. The deformity is analysed prior to surgery.
Clinical assessment and imaging allow precise quantification. The procedure
is performed by ring or unilateral frame and or IM nail in a continuous mo
de. The bone cut is performed percutaneously. Associated axial or rotationa
l deformities are corrected simultaneously - acutely or in a continuous mod
e. Callus distraction is preferably applied during childhood. For good outc
omecontrol of the patient is important during the inpatient and outpatient
treatment. Physiotherapy and orthotic treatment are mandatory, the same as
the managment of complications.
