Material and Methods: This prospective study was conducted in a tertiary ED. All patients’ measurements of the PQ muscle thickness in the longitudinal and transverse planes on both hand sides were performed by emergency medicine residents. For the diagnosis of an occult distal radius fracture and occult wrist injury, orthopedics and traumatology specialist’s opinion, which was decided as a result of the outpatient follow-up and additional examinations was used as reference. Results: No statistically significant difference was found between the PQ muscle thickness of 32 patients without occult wrist injury and 15 patients with occult injury and 6 patients with occult distal radius fracture. Also, no statistically significant difference was found between the PQ muscle thickness difference of the traumatic and non-traumatic sides. Conclusions: Sonographic measurement of PQ muscle thickness may not an effective method to detect occult distal radius fracture and other occult wrist injuries.}, number={3}, publisher={Türkiye Acil Tıp Derneği}
