Abstract:
OBJECTS: Synovial thickness in carpal tunnel was measured by high-resolution ultrasonography to evaluate the relation of synovial hypertrophy in idiopathic carpal tunnel syndrome. MATERIALS AND METHODS: Thickness of synovium of flexor tendons in 46 hands of idiopathic carpal tunnel syndrome and 50 hands of normal control were measured quantitatively by high-resolution ultrasonography. The patients were classified into three groups according to the clinical severity: Group I had typical clinical symptoms and positive provocation test (17 cases) , Group II had sensory decreation on the dermatome of median nerve (21 cases) , and Group III had sensory decreation and thenar muscle weakness. The thickness of flexor tendons in the three groups and control group were statistically compared. RESULTS: The mean value of thickness of carpal tunnel syndrome was 1.06mm and that of control group was 0.87mm (p=0.012) . Positive correlation was revealed according to the clinically classified three groups. CONCLUSION: Synovial hypertrophy in carpal tunnel has positive relationships with idiopathic carpal tunnel syndrome, and it reveal possibly the progression of the disease.
