A technique for calculating limb length inequality and epiphyseodesis timing using the multiplier method and a spreadsheet

Erratum to: J Child Orthop (2007) 1:151–155 DOI 10.1007/s11832-007-0016-6

In our spreadsheet for calculating proper timing of epiphyseodesis, an error has been identified in the interpolation equation for the multiplier. This error results in only minimal differences in the timing calculations and a corrected version is given below. I am grateful for this observation to Harald Steen MD/Ph.D, Biomechanics Lab, Department of Orthopaedics, Rikshospitalet University Hospital, Oslo, Norway.
