Objective
To suggest a safer and easier technique of suprascapular nerve block by assessing anatomical relationship of the suprascapular notch from a view point of surface anatomy. Method: Fourteen shoulders of seven cadavers were dissected in prone position. The scapular notch was exposed and the articular branch of suprascapular nerve was observed. The length and depth of spine, height and relative position of scapular notch were measured for all of the specimen. Results: The length of the spine was 11.45⁑0.72 cm. The injection point was measured as relative position of scapular notch on the spine. The ratio between distance from medial border of the spine to injection point and from the injection point to posterior angle of acromion was 1.89⁑0.2：1. The depth of the spine, which was defined as the shortest vertical distance from the injection point to the scapula was 2.69⁑0.43 cm, and the vertical distance from this contact point to the base of the scapular notch, e.g. the height of the scapular notch, was 1.18⁑0.1 cm. Conclusion: We expect we could perform suprascapular nerve block easily and safely with suggested surface landmarks and measured data in this study. (J Korean Acad Rehab Med 2005; 29: 630-634)

Objective
To determine the Korean adult standard of mean length and depth from spinous process which is palpable landmark of back to each facet joint. Method: The horizontal line was made between the posterior end of each facet joint, and the rectangular line was made on the horizontal line at the level of spinous process, respectively. We measured the length from the point of intersection to the posterior end of each facet joint (SFL), and the depth from the tip of spinous process to the point of intersection (SFD). All parameters were measured in 30 volunteers (Exp. 1) using computed tomography and in 30 cadavers (Exp. 2). Results: The lower lumbar spine revealed the longer SFL (p＜0.01). SFD was significantly increased from L1-L2 to L3-L4 facet joints, but significantly decreased in L5-S1 facet joint compared to L4-L5 facet joint (p＜0.01). There was no significant difference in laterality, gender, and viability (Exp. 1 and Exp. 2)(p＞0.05). There was no correlation with height and weight, either (r＜0.04). Conclusion: We measured the standard for SFL and SFD in Korean. We suggest that these results will be useful in clinical practice including blind approach of spinal intervention to the facet joints.
