Hip instability and scoliosis in children with spinal muscular atrophy: a single center retrospective study in the United Arab Emirates

Introduction: Hip instability is an important complication of spinal muscular atrophy (SMA), which leads to various functional impairments, including mobility challenges and difficulties with daily care. The primary objective of this study is to determine the prevalence and severity of hip instability in a cohort of SMA patients managed at a tertiary care center. The prevalence of scoliosis and its association with hip instability in children with SMA were also assessed. Methods: copies and disease modifying therapies (DMTs) received. Results: = 0.023). Several factors, including gender, age, motor status and presence of scoliosis were analysed, but none showed a statistically significant association with hip abnormalities. Discussion: To the best of our knowledge, this is the first study in the Middle East on hip instability and scoliosis in a cohort of children with SMA. Hip dislocation and/or subluxation is most common and most severe in type 1 SMA. The study's findings can aid the development of hip instability screening programs in SMA patients, enabling early intervention.
