Radial sensory nerve entrapment in the forearm

Area of Science:

• Orthopedic Surgery
• Neurology
• Hand Surgery

Background:

• Entrapment of the superficial sensory branch of the radial nerve (SSBRN) can cause significant hand and wrist pain.
• Symptoms often include altered sensation and pain on the dorsoradial aspect of the hand, exacerbated by specific movements and activities.

Purpose of the Study:

• To describe the clinical presentation, diagnostic findings, and treatment outcomes for patients with SSBRN entrapment.
• To evaluate the effectiveness of both nonoperative and surgical management strategies for SSBRN entrapment.

Main Methods:

• Retrospective case series of 51 patients diagnosed with SSBRN entrapment.
• Review of patient history, physical examination findings (including sensory testing and Tinel sign), and treatment modalities.
• Analysis of outcomes based on subjective improvement and return to work following nonoperative and surgical interventions.

Main Results:

• Nonoperative treatment yielded improvement in 37% of patients after a mean of 28 months.
• Surgical treatment resulted in excellent or good subjective improvement in 86% of patients.
• Following surgery, 43% of patients returned to their regular jobs, and 22% engaged in vocational rehabilitation or alternative employment.

Conclusions:

• Superficial radial nerve entrapment is a treatable condition causing distinct symptoms and physical findings.
• Surgical intervention demonstrates a high rate of subjective improvement and functional recovery, including return to work.
• Early diagnosis and appropriate management, including surgical decompression when indicated, are crucial for favorable outcomes in SSBRN entrapment.
