Matos et al. 2021 [18]

Cross-sectional case series study

• Cohort of 47 CZS newborns

• Females (n = 24), males (n = 23)

Propose a classification scheme for orthopedic deformities and musculoskeletal complications by incidence, severity, and progression (non-spastic, spastic, arthrogrypotic)

• Foot deformities: vertical talus, clubfoot (41.2%, n = 19)

• Hip deformity (29.8%, n = 14); hip adduction contracture (20.2%), hip displacement (7.5%)

• Knee deformity (12.8%, n = 6); knee displacement (6.4%)

• Hypertonia (72.3%, n = 34)

• Spasticity (77.3%, n = 36)

• Arthrogryposis (15.2%, n = 7) associated with spasticity and more severe deformities

• Hip and knee dislocation (29.8%, n = 14; 6.4%, n = 3)
