To investigate the accuracy of intra-articular injection of the basal joint and to determine the rate of soft-tissue extravasation of injected material in successful intra-articular injection, we injected the basal joint of 30 hands with radiopaque dye (with fluoroscopy guiding needle placement in 8 cases) and then used fluoroscopy to check injection accuracy. Results were recorded depending on the location of the injected dye on fluoroscopic examination. Rates of intra-articular accuracy and soft-tissue extravasation for successful intra-articular injections were 100% and 25% for the fluoroscopy-guided group and 81.8% and 25% for the "blind" group. This study's accuracy rate for intra-articular injection of the basal joint is comparable to the rates reported for injection of larger joints. There is a relatively high soft-tissue extravasation rate for successful intra-articular injection.
为了研究掌指关节腔内注射的准确性，并确定在成功的关节腔内注射中注射材料的软组织外渗率，我们对30只手的掌指关节注射了不透射线的染料（8例在透视引导下进行针的放置），然后使用透视检查注射的准确性。根据透视检查中注射染料的位置记录结果。透视引导组成功关节腔内注射的关节内注射准确率和软组织外渗率分别为100%和25%，“盲目”组分别为81.8%和25%。本研究中掌指关节腔内注射的准确率与较大关节注射所报告的准确率相当。成功的关节腔内注射存在相对较高的软组织外渗率。
