Summary

Duchenne muscular dystrophy management focuses on maintaining function and comfort. Corticosteroids and early spinal fusion for scoliosis can significantly delay disease progression and improve outcomes for affected boys.

Orthopedic and Surgical Management of the Patient With Duchenne Muscular Dystrophy.

Pediatrics·2018

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Duchenne muscular dystrophy (DMD) is a severe X-linked genetic disorder characterized by the absence of dystrophin.
  • It leads to progressive muscle degeneration, loss of ambulation in early adolescence, and premature death, typically by age 20.
  • Current management focuses on supportive care, as a cure for the underlying genetic defect is not yet available.

Purpose of the Study:

  • To review current medical, surgical, and rehabilitative strategies for managing Duchenne muscular dystrophy.
  • To highlight the efficacy of corticosteroids in preserving muscle function and strength.
  • To emphasize the critical role of early surgical intervention for scoliosis in DMD patients.

Main Methods:

  • Review of existing literature on Duchenne muscular dystrophy treatments.
  • Analysis of the impact of corticosteroids (prednisone, deflazacort) on muscle strength and function.
  • Evaluation of surgical interventions for lower extremity contractures and spinal deformities.

Main Results:

  • Corticosteroids have demonstrated a significant ability to delay muscle strength and function loss in boys with DMD.
  • Surgical release of contractures can offer functional benefits to select patients.
  • Early spinal fusion with segmental instrumentation is the most effective treatment for severe scoliosis, preventing pulmonary and cardiac complications.

Conclusions:

  • While a definitive cure for DMD remains elusive, a multi-faceted approach is crucial for patient care.
  • Pharmacological interventions like corticosteroids and timely surgical management, particularly for scoliosis, can substantially improve quality of life and prolong survival.
  • Proactive management of scoliosis is essential to prevent severe respiratory and cardiac compromise in DMD patients.
