Aim: The aim of this study was to investigate the predictive power of pronator quadratus (PQ) muscle thickness, which is measured by focused ultrasonography, in patients applied to the emergency department (ED) with wrist trauma and without bone pathology detected in plain radiography.
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.

Amaç: Bu çalışmanın amacı, acil servise el bileği travması ile başvuran ve direk grafide kemik patolojisi saptanmayan hastalarda odaklanmış ultrasonografi ile ölçülen pronator kuadratus (PQ) kas kalınlığının prediktif gücünün araştırılmasıdır.
Gereç ve Yöntemler: Bu prospektif çalışma üçüncü basamak bir acil serviste yürütülmüştür. Hastaların her iki taraftaki longitudinal ve transvers düzlemlerde tüm PQ kas kalınlığı ölçümleri acil tıp asistanları tarafından yapıldı. Gizli distal radius kırığı ve gizli el bileği yaralanmaları tanısı için ayaktan takip ve ek tetkikler sonucunda karar veren ortopedi ve travmatoloji uzman görüşü referans alındı.
Bulgular: Gizli bilek yaralanması olmayan 32 hasta ile gizli yaralanması olan 15 hastanın ve gizli distal radius kırığı olan 6 hastanın PQ kas kalınlıkları arasında istatistiksel olarak anlamlı bir fark bulunmadı. Ayrıca travmatik ve travmatik olmayan tarafların PQ kas kalınlık farkı arasında istatistiksel olarak anlamlı bir fark bulunmadı.
Sonuç: PQ kas kalınlığının sonografik ölçümü, gizli distal radius kırığını ve diğer gizli el bileği yaralanmalarını saptamak için etkili bir yöntem olmayabilir.
