Anatomical Basis of Clinical Features of Erb's Palsy and Klumpke's Paralysis

Understanding Klumpke's Paralysis

Klumpke’s paralysis is a neurological condition resulting from injury to the lower brachial plexus, specifically C8 and T1 nerve roots. This can lead to motor and sensory deficits affecting the hand and forearm.

Clinical Presentation

Patients with Klumpke's paralysis often exhibit:

• Weakness or paralysis in intrinsic hand muscles
• Claw hand deformity due to unopposed action of long flexors
• Possible Horner's syndrome if T1 sympathetic fibers are affected
• Sensory loss along the medial aspect of the forearm and hand

Causes and Risk Factors

Common causes include:

• Traumatic injuries (e.g., excessive arm traction during childbirth)
• Falls leading to hyperextension of the arm
• Compression due to tumors or vascular anomalies

Diagnosis and Treatment

Diagnosis is based on clinical examination and may be confirmed through electromyography or nerve conduction studies.

Treatment involves:

• Physical therapy to strengthen affected muscles
• Occupational therapy for hand function improvement
• Surgical intervention in severe cases

Conclusion

Klumpke’s paralysis significantly impacts hand function and quality of life. Early intervention and rehabilitation are essential for optimal recovery.
