To standardize a technique of delivering a local anesthetic to the posterior interosseous nerve (PIN) and anterior interosseous nerve (AIN) by using the anatomic landmarks of the wrist and to evaluate the accuracy of the technique in a cadaver model.
Techniques for PIN and AIN injection and for PIN injection alone are described. Techniques were tested in a fresh frozen cadaver model by using methylene blue injections. Stained nerves were dissected under loupe magnification. Digital photographic images were taken of each nerve. Staining was quantified by calculating the mean density and area stained.
For both techniques methylene blue was delivered accurately to the PIN in 100% of the samples. Methylene blue was delivered accurately to the AIN in 100% of samples in which it was injected.
These techniques saturated successfully the PIN and AIN and may be useful as diagnostic and therapeutic tools for chronic wrist pain and in evaluating presurgically the effectiveness of partial wrist denervation.
通过利用腕部的解剖标志来规范一种向后骨间神经（PIN）和前骨间神经（AIN）注射局部麻醉剂的技术，并在尸体模型中评估该技术的准确性。
描述了PIN和AIN联合注射技术以及单独PIN注射技术。通过使用亚甲蓝注射在新鲜冷冻尸体模型中对这些技术进行测试。在放大镜放大下解剖染色的神经。对每条神经拍摄数码照片。通过计算染色的平均密度和面积对染色进行量化。
对于这两种技术，100%的样本中亚甲蓝都准确地注射到了PIN。在注射了亚甲蓝的样本中，100%准确地注射到了AIN。
这些技术成功地使PIN和AIN达到饱和，可能作为慢性腕部疼痛的诊断和治疗工具，并在术前评估部分腕部去神经支配的有效性方面有用。
