Anatomical Basis of Saturday Night Palsy

Introduction

Saturday Night Palsy is a condition resulting from prolonged compression of the radial nerve, often occurring when a person sleeps with their arm draped over the back of a chair. This leads to transient or sometimes lasting nerve damage, affecting motor and sensory functions.

Anatomical Basis

The radial nerve originates from the brachial plexus and travels down the arm, supplying sensory and motor functions. When compressed, particularly in the spiral groove of the humerus, neuropraxia or axonotmesis may occur, leading to weakness, numbness, and wrist drop.

Management and Treatment Options

Immediate Care

• Removal of compressive forces to prevent further nerve damage.
• Application of splints to support wrist extension.
• Physical therapy and occupational therapy for functional recovery.

Medical Treatment

• NSAIDs to reduce inflammation.
• Vitamin B supplementation to promote nerve healing.
• Steroid therapy in severe cases.

Surgical Intervention

Surgical exploration may be necessary in cases where nerve damage is persistent beyond six months.

Prognosis

Most cases of Saturday Night Palsy resolve within weeks to months with proper management, though severe cases may result in long-term deficits.
