A patient with an inferior lumbar myelomeningocele may develop hip flexion contractures due to which factor?

A patient with an inferior lumbar myelomeningocele can indeed develop hip flexion contractures due to multiple contributing factors, making the selection of the comprehensive answer the most appropriate.

In the context of a child with inferior lumbar myelomeningocele, there is often significant compromise to the function of motor control in the lower extremities. The lack of hip extensors to act as antagonists plays a crucial role; when hip flexor muscles are unopposed due to weakness or paralysis of the extensors, they can tighten and lead to contractures.

Additionally, parental non-compliance with home stretching programs can exacerbate the risk of developing contractures. Stretching is essential for maintaining flexibility in the hips and preventing contracture formation, especially in children with limited mobility. If caregivers are not consistent in implementing these programs, the likelihood of contractures increases.

Furthermore, good knee extension can contribute to the development of hip flexion contractures. If the knee is able to extend, it may inadvertently allow the hip flexors to tighten further, as the kinetic chain can influence the positions and tension at the hip joint.

Thus, considering all of these factors—muscle imbalances, compliance with care, and joint mechanics—this comprehensive understanding
