Rovsing's Sign: Clinical Significance
A positive Rovsing's sign indicates acute appendicitis and is elicited by palpating the left lower quadrant, which produces pain in the right lower quadrant due to peritoneal irritation from an inflamed appendix. 1
Diagnostic Value in Acute Appendicitis
In Pediatric Patients
- Rovsing's sign is among the most reliable physical examination findings for diagnosing acute appendicitis in children, along with absent or decreased bowel sounds, positive psoas sign, and positive obturator sign 1
- The sign demonstrates high clinical utility when incorporated into pediatric diagnostic algorithms 1
In Adult Patients
- While valuable, Rovsing's sign is less discriminatory in adults compared to other findings such as right lower quadrant pain, abdominal rigidity, and periumbilical pain radiating to the right lower quadrant 1
- One study found Rovsing's sign had reasonable sensitivity but was not significantly different from other physical signs in terms of specificity and positive predictive value 2
Clinical Context and Integration
Role in Diagnostic Approach
- Physical examination findings, including Rovsing's sign, should be part of a step-up diagnostic approach beginning with clinical and laboratory examination, progressing to imaging when needed 3
- Early clinical evaluation incorporating physical signs like Rovsing's helps optimize diagnostic testing and enables earlier implementation of proper management plans 3
Combination with Other Findings
- Rovsing's sign should not be interpreted in isolation but rather combined with other clinical features such as fever, migratory pain to the right lower quadrant, and laboratory findings 1
- Clinical risk scores (Alvarado score, Pediatric Appendicitis Score, Appendicitis Inflammatory Response score) incorporate multiple findings to stratify patients as low, moderate, or high risk 1
Important Caveats
Technical Accuracy
- There is significant concern that Rovsing's sign is described and performed incorrectly in current medical literature and teaching 4
- A 2014 study found that no English surgical textbooks described the sign accurately, though German textbooks provided correct descriptions 4
- All statistical data on this sign's diagnostic value must be questioned due to widespread erroneous application 4
Clinical Implications
- Despite technical controversies, the sign remains clinically useful when properly elicited 1, 5, 2
- The presence of a positive Rovsing's sign should prompt consideration of imaging (ultrasound as first-line, followed by CT if inconclusive) to confirm the diagnosis 3
- In moderate- to high-risk patients with positive findings, surgical consultation should be accomplished quickly to reduce morbidity and mortality from perforation, which occurs in 17% to 32% of acute appendicitis cases 1
