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.
