Anatomical Basis of Saturday Night Palsy

Introduction

Saturday Night Palsy is a condition caused by prolonged compression of the radial nerve, often occurring after deep sleep with an arm in an awkward position. Understanding its anatomical basis is crucial for effective diagnosis and management.

Anatomical Basis

The radial nerve originates from the brachial plexus and travels along the humerus. Prolonged compression of the nerve at the spiral groove can lead to neuropraxia, impairing motor function and sensation.

Clinical Features

• Weakness in wrist and finger extension
• Numbness along the dorsal hand and lateral forearm
• Absent brachioradialis reflex

Management and Treatment

Treatment involves conservative and medical approaches:

• Physical Therapy: Exercises to restore strength and mobility.
• Splinting: Wrist splints to prevent further nerve damage.
• Medications: NSAIDs for pain management.
• Surgical Intervention: Rare, but considered for persistent cases.

Conclusion

Early recognition and appropriate management of Saturday Night Palsy can lead to complete recovery. Physicians should educate patients about prevention strategies and ergonomic positioning.
