Diagnostic Value Evaluation of Bed Ultrasound Compared with Wound Openness to Diagnose Tendon Rupture in Penetrating Hand Trauma at Taleghani Hospital in Kermanshah, 2019.

Objective: To determine the sensitivity, specificity and accuracy of ultrasound to diagnose the patients with tendon rupture of upper extremity referred to Taleghani Hospital's center of Kermanshah in 2019.

Methods: This was a diagnostic value study which performed on 113 patients with non-fracture penetrating hand trauma. In the first stage, all patients have been diagnosed with tendon injury by a first-year resident and then ultrasound was performed by a trained 2^nd year resident in emergency medicine ward and the results were recorded in a checklist. Further examination of the tendon was performed as well as exploring the site for the patients after the patient was transferred to the orthopaedic service. Final result was recorded in the checklist. Data were analysed by SPSS software and sensitivity and specificity of ultrasound have been calculated.

Results: Results showed that ultrasound was able to identify 73 patients of 77 individuals with tendon injury. Of the patients with complete rupture, 45 individuals were correctly diagnosed based on the results of surgery in ultrasound test. Ultrasound and surgical findings were significantly different. Of the 36 individuals without confirmed rupture in surgery, 10 cases were diagnosed with tendon rupture by ultrasound. Of 52 cases of complete rupture based on surgical findings, 45 individuals were correctly diagnosed based on the results of surgery. Twenty-one patients were correctly diagnosed based on ultrasound out of 25 cases of partial rupture based on surgical findings.

Conclusion: Overall, the results of the present study show that ultrasound is not very sensitive and specific in diagnosing of upper extremity tendon rupture and cannot be used as a reliable alternative in diagnosing of upper exteremity rupture; however, further studies is essential according to the limitations of this research. The limitations were low sample size in subgroups analysis based on the presence of complete or partial rupture and performing the ultrasound by an emergency medicine resident who is less experienced rather than radiologists.
