In a cadaver dissection study the relation of the arthroscopic portals to the neurovascular structures was documented. In six cadaveric elbows the capsule was distended with 35-40cc fluid of 0.9% NaCl by using the direct lateral portal. An anterolateral and anteromedial approach to the elbow joint were established. The distance of the arthroscopic portals to the neurovascular bundles were measured at empty and filled joint after performing an anatomic dissection. The influence of flexion and extension of the joint as well as pronation and supination of the forearm on the distance of the arthroscopic sheath to the neural structures was documented. Lesions of the superficial cutaneous nerves were not seen. Using the anterolateral portal in the best position of the joint (90 degrees flexion and not distended joint at max. pronation of the forearm) we measured a proximity of 4.5 mm (range 2-10 mm) to the radial nerve. For the anteromedial approach the mean distance of the median nerve to the arthroscopic sheath was 15.5 mm (range 8-27 mm), when the optimal joint position was used (90 degrees flexed joint, distended, max. supination of the forearm).
在一项尸体解剖研究中，记录了关节镜入路与神经血管结构的关系。在6具尸体肘部，通过直接外侧入路向关节囊内注入35 - 40cc的0.9%氯化钠溶液。建立了肘关节的前外侧和前内侧入路。在进行解剖后，测量了关节镜入路在关节空虚和充盈时与神经血管束的距离。记录了关节的屈伸以及前臂的旋前和旋后对关节镜鞘与神经结构距离的影响。未发现浅皮神经损伤。在关节的最佳位置（90度屈曲且关节未充盈，前臂最大旋前）使用前外侧入路时，我们测量到其与桡神经的距离为4.5毫米（范围为2 - 10毫米）。在前内侧入路中，当使用最佳关节位置（90度屈曲的关节、充盈、前臂最大旋后）时，正中神经与关节镜鞘的平均距离为15.5毫米（范围为8 - 27毫米）。
