The long-term effect of femoral leg lengthening on muscle strength - A 10-year follow-up.

ABSTRACT:

Introduction

Callus distraction during leg lengthening procedures often leads to a reduction in muscle strength. This study explores whether this decline is temporary or if it persists long-term, with a follow-up period of 10 years.

Materials and methods

A cohort of nine patients underwent femoral lengthening with a motorized intramedullary device. We measured the maximum isokinetic concentric torque of the knee extensors and flexors preoperatively, at 2 years and at 10 years postsurgery. For this analysis, we included all patients with a full dataset and a minimum follow-up of 10 years (n = 9). We analyzed the differences between preoperative and postoperative maximal isokinetic torques and compared them with a control group of 10 healthy individuals.
