Anatomical basis of clinical features of Erb's palsy and Klumpke's paralysis
Pathophysiology of Klumpke's paralysis: Injury to the lower brachial plexus (C8-T1 roots) leading to motor and sensory impairments
Klumpke's paralysis results from lower brachial plexus injury (C8-T1), leading to claw hand deformity and sensory loss. Proper diagnosis and management can improve patient outcomes.
Anatomical Basis of Clinical Features of Erb's Palsy and Klumpke's Paralysis
Introduction
Erb's palsy and Klumpke's paralysis are two distinct brachial plexus injuries affecting different nerve roots.
Pathophysiology of Klumpke's Paralysis
Klumpke's paralysis occurs due to damage to the lower brachial plexus (C8-T1 roots), leading to motor and sensory deficits primarily in the hand and forearm.
Clinical Features
- Weakness or paralysis of intrinsic hand muscles
- Claw hand deformity
- Loss of sensation along the medial aspect of the forearm and hand
Diagnosis and Management
Diagnosing Klumpke's paralysis involves clinical examination and electrophysiological studies. Treatment may include physiotherapy and surgical intervention.
Conclusion
Understanding the anatomical basis of Klumpke's paralysis helps in accurate diagnosis and effective management.
