Abstract

Background: There are many methods for evaluating a traumatized metacarp.
Objectives: We aimed to check the accuracy of metacarpal compression test for diagnosis of metacarpal fracture.
Methods: All patients with trauma to metacarp, were tested with axial load (compression) on metacarp, induction or augmentation of pain on each metacarps during axial pressure was recorded. Then an X-Ray was performed, the presence of fracture on x-ray was recorded. All data was entered to a 2*2 table, then negative predictive value (NPV), positive predictive value (PPV), Sensitivity and Specificity of test were established.
Results: After careful physical examination and application of the axial pressure on metacarpal bone, 16(23.68%) patients didn’t report any pain during axial loading of which none had fracture. statistical analyses of the data, showed a result of 69% specificity, 100% sensitivity, 86% PPV and 100% NPV
Conclusion: Our finding shows axial loading applied on the metacarpal bone when leads to pain, can be determined as a good marker for fracture. On the other hand, patients with negative test results had no fracture in radiography, which emphasized 100% NPV of test.
