We conducted a study to evaluate aspiration of the third dorsal compartment as a therapeutic option for preventing extensor pollicis longus ruptures in association with distal radius fractures. A cadaveric model with a nondisplaced distal radius fracture was created, and radiopaque (Hypaque) dye was injected into the fracture site. Pressure readings were taken from the third dorsal compartment before and after dye injection. The compartment was aspirated with an 18-gauge needle, and compartment pressures were measured again. There was a significant decrease in pressures after aspiration. Results in our cadaveric model were consistent with those in in vitro decompression of the third dorsal compartment. Clinical studies may determine that in-office needle aspiration is beneficial in preventing extensor pollicis longus rupture in nondisplaced distal radius fractures.
我们开展了一项研究，以评估抽吸第三背侧间室作为预防与桡骨远端骨折相关的拇长伸肌断裂的一种治疗选择。创建了一个伴有无移位桡骨远端骨折的尸体模型，并将不透射线（泛影葡胺）染料注入骨折部位。在染料注射前后，从第三背侧间室获取压力读数。用18号针头抽吸该间室，然后再次测量间室压力。抽吸后压力显著降低。我们尸体模型的结果与第三背侧间室体外减压的结果一致。临床研究可能会确定，门诊针刺抽吸在预防无移位桡骨远端骨折中的拇长伸肌断裂方面是有益的。
