Rotational control of unstable subcapital fractures. An experimental study
JD Baril ; DA Sonstegard ; LS Matthews


An experimental evaluation of the stability of rotational fixation of unstable, subcapital femoral-neck fractures as provided by either the multiple pin and side-plated Deyerle device or the heavy duty Jewett triflanged nail showed no significant difference between the two devices. The determination of moment versus deformation behavior included study of two torsional axis orientations and superposition of simulated body-weight and muscular-force impaction loadings.
