There is no standardized approach to the greater occipital nerve (GON) block technique for treating occipital neuralgia. The aim of the present study was to validate the previously-suggested guidelines for conventional injection techniques and to provide navigational guidelines for safe GON block. The GON, lesser occipital nerve (LON) and occipital artery (OA) were carefully dissected in the occipital region of embalmed cadavers. ⋯ The safe injection points on the EOP-MP line are about 3 cm from the EOP, 1 cm inferior parallel to the EOP-MP line, and about 3 cm away from the MP.

The use of dorsal cutaneous branch of the ulnar nerve (DCBUN) transfer for median nerve (MN) sensory restoration has not been evaluated anatomically and histologically in humans. The purpose of this study was to evaluate the feasibility of DCBUN to MN transfer for sensory restoration with respect to nerve branch pattern, length, and fascicle count match. Using seven fresh frozen cadaveric upper limb specimens, the DCBUN and its branch patterns, lengths, and sizes were recorded. ⋯ The individual size of the DCBUN branch is smaller than CDN; however, combining two or more branches of the DCBUN would overcome the fascicle and size mismatch to reconstruct the 1st web space CDN for critical sensory restoration.
