Abstract

Muscle imbalance is related to persistent internal hip rotation (IHR) after femoral derotation osteotomy (FDO) in cerebral palsy (CP). The aim of this study was to evaluate the effect of the Majestro-Frost soft tissue procedure (MFP), which potentially addresses muscle imbalance, on IHR in CP patients during walking. A retrospective study of an existing database (medical records and gait laboratory data) was conducted and a search was performed using the following inclusion criteria: (1) diagnosis of spastic CP, (2) GMFCS levels I-III; (3) mean IHR during stance phase higher than 11° at baseline; (4) individuals who received single event multilevel orthopedic surgery in the lower limbs and had three-dimensional gait analyses (3DGA) before and after the intervention. Patients who underwent a FDO were excluded. Eighty-three individuals were considered for the study and they were divided into two groups: No MFP (45 patients who did not receive a MFP) and MFP (36 patients who underwent a MFP). A full clinical examination and 3DGA, with kinematics calculated according to a standard software procedure (Plugin Gait), were performed before and after the intervention, and the results were compared. The studied groups matched regarding d...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
