De Quervain's Tenosynovitis Diagnosis and Treatment

Diagnostic Tests

• The American College of Radiology recommends using the Allen Test to assess the patency of radial and ulnar arteries, but it is not appropriate for diagnosing tendon disorders, whereas the Hawkins-Kennedy Test and Yergason Test are used for diagnosing shoulder impingement and biceps tendon pathology, respectively, and are not suitable for wrist disorders 1
• The Phalen Test is used for diagnosing carpal tunnel syndrome, which typically presents with numbness and tingling, and is not applicable in this case 2

Diagnosis and Treatment Guidelines

• The American College of Radiology guidelines note that clinical examination is the cornerstone for detecting tenosynovitis, with imaging studies like MRI or ultrasound reserved for unclear cases or treatment planning 1
• The American College of Radiology guidelines also support the use of clinical examination, and the American College of Radiology recommends considering ultrasound imaging if the diagnosis is still unclear, which can detect tenosynovitis with high specificity 2
• Corticosteroid injections can resolve symptoms in approximately 61% of cases after a single injection, according to the American College of Radiology guidelines 2

Patient Population and Risk Factors

• De Quervain's tenosynovitis is particularly common in women aged 30-50 years and postpartum women, according to the American College of Radiology guidelines 2
