Brachial plexus palsy in neonates and children
Insights
This study evaluated conservative treatment for 135 children with obstetrical palsy, focusing on preventing contractures and maintaining strength. Surgical interventions like osteotomy showed functional improvement, while most patients experienced mild residual deficits.
Area of Science:
- Pediatric Neurology
- Orthopedic Surgery
- Rehabilitation Medicine
Background:
- Obstetrical palsy affects newborns, leading to significant motor deficits.
- Conservative management is crucial for preventing long-term complications like contractures and muscle weakness.
Purpose of the Study:
- To design a conservative treatment program for children with obstetrical palsy.
- To evaluate the effectiveness of various interventions, including surgical options, for improving function.
Main Methods:
- Clinical and electrodiagnostic studies were used for initial and serial evaluations.
- Conservative strategies focused on preventing contractures and maintaining muscle strength.
- Surgical interventions included rotational osteotomy of the humerus and muscle transfers.
Main Results:
- 70% of patients had mild residual deficits, 22% moderate, and 8% severe.
- Rotational osteotomy and muscle transfer improved function.
- Shoulder and elbow surgery improved cosmesis but not function.
Conclusions:
- A comprehensive conservative approach is key for managing obstetrical palsy.
- Early surgical interventions like osteotomy and muscle transfer can enhance functional outcomes.
- Individualized treatment plans are essential, considering factors like denervation and limb awareness.
Abstract:
In 135 children with obstetrical palsy, clinical and electrodiagnostic studies on inital and serial evaluation aided in designing a conservative treatment program. Prevention of contractures, maintenance of muscle strength and reinforcing the child's awareness of the affected limb were predicated on the limiting factors of permanent denervation and agnosia. Instability of the scapula, scapulohumeral adhesions and elbow flexion with loss of active supination defy conventional range of motion exercises. Forced passive supination of the elbow may actually compound the problem of radial head dislocation and ulnar bowing. Because of the young age of most of the patients, only 7 have had orthopedic intervention. Rotational osteotomy of the humerus and transfer of intact muscles seem to improve function. Prior to selection of muscles for transfer, electromyography is advised. Later surgical treatment of the shoulder and elbow seems to improve cosmesis but not function. Of the 135 children, 70% had mild residua, 22% showed moderate impairment and 8% had severe deficit.
