Signficant Femoral Version Abnormalities and Patient-Reported Quality of Life.

INTRODUCTION: The purpose of this study was to determine how the Limb Deformity-Modified Scoliosis Research Society (LD-SRS) and Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire scores differ between patients with femoral version abnormalities and healthy control subjects. METHODS: A retrospective database review identified patients with femoral version abnormalities between December 2018 and September 2022. A total of 21 adult patients scheduled for femoral derotational osteotomy and 33 control subjects were included. All individuals completed the LD-SRS and PROMIS questionnaires. RESULTS: Patients with femoral version abnormalities reported significantly worse scores than control subjects on all LD-SRS and PROMIS domains: LD-SRS (Total [3.46 ± 0.66 vs. 4.58 ± 0.37, P < 0.001]; Function/Activity [3.48 ± 0.83 vs. 4.44 ± 0.4, P < 0.001]; Mental Health [3.41 ± 0.96 vs. 4.3 ± 0.73, P < 0.001]; Pain [3.55 ± 0.9 vs. 4.81 ± 0.31, P < 0.001]; and Self-Image/Appearance [3.37 ± 0.79 vs. 4.75 ± 0.43, P < 0.001]) and PROMIS (Function [41.6 ± 7.58 vs. 60.0 ± 7.28, P < 0.001]; Pain Intensity [45.85 ± 8.04 vs. 33.7 ± 4.89, P < 0.001]; Pain Interference [56.78 ± 9.63 vs. 42.8 ± 6.6, P < 0.001]; Global Mental Health [47.97 ± 9.68 vs. 55.3 ± 7.81, P = 0.004]; and Global Physical Health [45.23 ± 7.49 vs. 58.2 ± 7.07, P < 0.001]). DISCUSSION: Patients with femoral version abnormalities reported markedly worse quality of life as measured on the LD-SRS and PROMIS scores compared with healthy control subjects. The combination of these two surveys effectively captures the multifaceted quality-of-life-deficit individuals with excessive femoral version may experience.
