The role of femoral obliquity angle and T1 pelvic angle in predicting quality of life after spinal surgery in adult spinal deformities

Abstract Background Adult spinal deformities (ASD) represent a growing clinical condition related to chronic pain, disability and reduction in quality of life (QoL). A strong correlation among spinal alignment, spinopelvic parameters and QoL after spinal fusion surgery in ASD patients was thoroughly...

A strong correlation among spinal alignment, spinopelvic parameters and QoL after spinal fusion surgery in ASD patients was thoroughly investigated over the last decade, However, only few studies focused on the relationship between lumbo-pelvic-femoral parameters - such as Femoral Obliquity Angle (FOA), T1 Pelvic Angle (TPA) and QoL. Methods Radiological and clinical data from 43 patients surgically treated with thoracolumbar posterior spinal fusion for ASD between 2015 and 2018 were retrospectively analyzed. The primary outcomes were the correlation between preoperative spino-pelvic-femoral parameters and postoperative clinical, functional outcomes and QoL. Secondary outcomes were: changes in sagittal radiographic parameters spino-pelvic-femoral, clinical and functional outcomes and the rate of complications after surgery. Results Using Spearman’s rank correlation coefficients, spinopelvic femoral parameters (FOA, TPA, pre and post-operative) are directly statistically correlated to the quality of life (ODI, SRS-22, pre and post-operative; > 0,6 strong correlation, p < 0.05). Stratifying the patients according pre preoperative FOA value (High FOA ≥ 10 and Normal/Low FOA < 10), those belonging to the first group showed worse clinical (VAS: 5.2 +/− 1.4 vs 2.9 +/− 0.8) and functional outcomes (ODI: 35.6+/− 6.8 vs 23.2 +/− 6.5) after 2 years of follow-up and a greater number of mechanical complications (57.9% vs 8.3% p < 0.0021). Conclusion Based on our results, preoperative FOA and TPA could be important prognostic parameters for predicting disability and quality of life after spinal surgery in ASD patients and early indicators of possible spinal sagittal malalignment. FOA and TPA, like other and better known spinopelvic parameters, should always be considered when planning corrective surgery in ASD patients.Andrea PernaLuca ProiettiAmarildo SmakajCalogero VellutoMaria Concetta MeluzioGiuseppe RovereDaniela FlorioGianfranco ZirioFrancesco Ciro TamburrelliBMCarticleAdult spinal deformitiesSagittal imbalanceFemoral obliquity angleSpinopelvic parametersSpinal deformity correctionDiseases of the musculoskeletal systemRC925-935ENBMC Musculoskeletal Disorders, Vol 22, Iss S2, Pp 1-10 (2021)
