Summary

External oblique muscle transfer improved gait and reduced limp in 17 of 18 patients with hip abductor paralysis from poliomyelitis. Nine patients no longer needed walking aids, showing significant functional recovery.

Area of Science:

  • Orthopedic surgery
  • Reconstructive surgery
  • Pediatric orthopedics

Background:

  • Hip abductor paralysis, often resulting from poliomyelitis, significantly impairs gait and mobility.
  • Restoring hip abductor function is crucial for improving ambulatory function and quality of life.

Purpose of the Study:

  • To evaluate the efficacy of external oblique muscle transfer in patients with hip abductor paralysis.
  • To assess functional outcomes, patient satisfaction, and the reliability of a scoring system for predicting results.

Main Methods:

  • A cohort of 18 patients (5 male, 13 female) with poliomyelitis-induced hip abductor paralysis underwent external oblique muscle transfer.
  • Patients were followed for an average of 5 years (range, 2-11 years) with gait analysis and a detailed scoring system.

Main Results:

  • Seventeen patients demonstrated improved gait, with reduced limp and swaying, and enhanced long-distance walking ability.
  • Nine patients achieved ambulation without assistive devices. Subjective improvement was noted in 16 patients, primarily due to aesthetic enhancement.
  • The scoring system yielded 6 excellent, 6 good, 3 fair, and 3 poor results, correlating well with overall outcomes.

Conclusions:

  • External oblique muscle transfer is an effective surgical option for hip abductor paralysis secondary to poliomyelitis.
  • The procedure significantly improves gait, functional independence, and patient satisfaction.
  • The developed scoring system serves as a valuable tool for predicting surgical outcomes in this patient population.
