Proximal spinal muscular atrophy: current orthopedic perspective

Area of Science:

• Neurology
• Orthopedics
• Genetics

Background:

• Spinal muscular atrophy (SMA) is a genetic neuromuscular disorder characterized by progressive muscle weakness and atrophy due to defective survival motor neuron (SMN) protein.
• While SMA presents with varied severity and high mortality, advances in supportive care have improved quality of life and life expectancy.
• The identification of the SMA gene defect in 1995 has spurred research into potential treatments, though causal therapies are still lacking.

Purpose of the Study:

• This review focuses on the orthopedic management of spinal muscular atrophy (SMA).
• It discusses key orthopedic aspects including scoliosis, contractures, hip disorders, and fractures.
• The review also compares conservative and surgical treatment approaches and highlights associated complications.

Main Methods:

• Literature review of orthopedic management strategies for spinal muscular atrophy.
• Analysis of established orthopedic procedures and technical devices.
• Discussion of multidisciplinary approaches integrating orthopedic care with respiratory, nutritional, and rehabilitation support.

Main Results:

• Adequate orthopedic therapy, utilizing established procedures and devices, can significantly improve the disease course of SMA.
• Multidisciplinary management is crucial for addressing the complex orthopedic, respiratory, and nutritional challenges faced by individuals with prolonged survival.
• Comparative analysis of conservative versus surgical interventions provides insights into optimal treatment selection.

Conclusions:

• Effective orthopedic management is essential for enhancing the quality of life and functional outcomes in patients with spinal muscular atrophy.
• A comprehensive, multidisciplinary approach is vital for addressing the multifaceted needs of the growing SMA population.
• Continued research and established orthopedic interventions offer promising avenues for improving long-term patient care and prognosis.
