Assessment of the quality of life in patients with varying degrees of equalization of lower limb length discrepancy treated with Ilizarov method

Abstract

Background

Inequalities in leg length result in functional disorders, as they impair the biomechanics of the musculoskeletal system, significantly reducing the quality of life (QoL). This study used the WHOQoL-BREF questionnaire in patients with varying degrees of lower leg shortness who had undergone treatment by the Ilizarov method, compared to a healthy control group.

Methods

Fifty-eight patients treated with the Ilizarov method for discrepancies in lower limb length were grouped by degree of limb equalization (group 1, 37 treated individuals with limb length discrepancy < 1 cm; group 2, 21 individuals with discrepancy ≥ 1 cm but not more than 4 cm). The control group 3 contained 61 healthy individuals. Patient quality of life (QoL) was assessed using a shortened version of the WHOQoL-BREF questionnaire, at least 24 months after the end of Ilizarov therapy.

Results

Control subjects obtained higher scores in all domains than subjects in both treatment groups, as well as significantly higher self-assessed QoL, and health, in the physical, psychological, social, and general lifestyle domains, as compared to those with inequalities ≥ 1 cm. Furthermore, patients with inequalities ≥ 1 cm had higher odds ratios of low self-assessment (3.28 times; p = 0.043), low self-assessment of health (4. 09 times; p = 0.047), and low physical and psychological domains (respectively 6.23 times; p = 0.005 and 8.46 times, p = 0.049) compared with patients with inequality < 1 cm. The shortened version of the WHOQoL questionnaire was used.

Conclusions

After at least 24 months of treatment with the Ilizarov method, patients with limb length discrepancy < 1 cm did not differ significantly from healthy individuals in the WHOQoL self-assessment of mental functioning, social, or life satisfaction.
