The radial head-capitellum (RHC) view was assessed in a prospective study of 130 patients with acute elbow trauma in whom 35 fractures were identified. The RHC view demonstrated only 16 of the 32 fractures available for review, including one fracture that was not seen on routine projections. Fat pads were displaced in all 31 patients with fractures; fat-pad displacement was demonstrated on the true lateral view in 29 and on the conventional radial-head view in two patients. Routine use of the RHC projection is not justified in all cases of elbow trauma. It may be added in cases in which no fracture has been identified but clinical suspicion remains high or displaced fat pads are seen on the routine projections.
在一项对130例急性肘部创伤患者的前瞻性研究中评估了桡骨头-肱骨小头（RHC）位片，其中发现了35处骨折。RHC位片仅显示了32处可供评估的骨折中的16处，包括1处常规投照未发现的骨折。所有31例骨折患者均有脂肪垫移位；29例患者在真正侧位片上显示脂肪垫移位，2例患者在常规桡骨头位片上显示脂肪垫移位。在所有肘部创伤病例中常规使用RHC位投照并不合理。在未发现骨折但临床怀疑度高或常规投照发现脂肪垫移位的情况下可加拍该位片。
