The effect of post-traumatic long bone non-unions on health-related quality of life.

Background: Fracture non-unions have a detrimental effect on patients due to reduced mobility and severe pain. Current literature on the quality of life in non-unions is limited, hence the purpose of this study, to quantify the health-related quality of life (HRQoL) among patients with post-traumatic long bone non-unions. It was hypothesized that the HRQoL of these patients is lower than the Dutch population standard as well as for multiple chronic diseases and musculoskeletal disorders.

Patients And Methods: From January 2020 to December 2021, this study included consecutive patients who were referred to a multidisciplinary (trauma, orthopedic and plastic surgery), non-union clinic at the Maastricht UMC+. All non-unions were evaluated using the Non-Union Scoring System (NUSS) questionnaire. Patient reported HRQoL outcomes were acquired using the EQ-5D-5L questionnaire and the Lower Extremity Functional Scale (LEFS).

Results: 50 patients were included, 18 females and 32 males, with a mean age of 55 years (± 15.5 SD). Eighteen patients presented with an open fracture, nine non-unions were infected and 39 patients had a lower extremity non-union. The mean NUSS score was 39.61 (± 14.6 SD). The mean EQ-5D-5L index score was 0.490 (± 0.261 SD), where patients experienced most problems with mobility. The mean EQ-5D-5L VAS was 61.4 (± 19.6 SD). The patients had a mean LEFS score of 28.7 (± 16.4 SD). The health-related quality of life was well below the age-corrected normative score of the Dutch population (EQ-5D-5L 0.857(p < 0.001); LEFS 77(p < 0.001)). This cohort's HRQoL was significantly lower than the HRQoL of multiple chronic and musculoskeletal disorders, including different forms of cancer and osteoarthritis.

Conclusions: This study has quantified the detrimental effect of post-traumatic long bone non-unions on patient's health-related quality of life, being significantly lower than the HRQoL of the Dutch population as well as for multiple chronic and musculoskeletal medical conditions. This cohort demonstrates a patient population in need of more specialized care with a low health-related quality of life.
