Objective: superior gluteal nerve is composed of L4, L5, S1 nerve anterior branch, after piriformis hole out of pots, accompanied by the superior gluteal artery running between the gluteal muscles and hip small. Superior gluteal nerve pain in recent years, more and more researchers pay attention to it, is also one of the more common causes of leg pain caused by the few related topics rarely reported. Superior gluteal nerve pain caused by many reasons, such as the narrow tunnel of the superior gluteal nerve running around aponeurosis, fascia hyperplasia, hypertrophy, adhesion, etc. caused by nerve entrapment. Prior to the superior gluteal nerve entrapment caused a series of leg pain often are considered gluteus fasciitis, cutaneous neuritis, piriformis syndrome. And because of the superior gluteal nerve running between the gluteal muscles and hip small, that is, its location deep so caused pain long to make patients feel in a deeper position and appear not accurate positioning. Peripheral nerve entrapment syndrome definition, superior gluteal nerve compression syndrome understood as superior gluteal nerve after bone fibrous tunnel, fascia, muscle, tendon and other structures generated due to a variety of damage factors causing inflammation, hyperplasia, hypertrophy oppressed, adhesions, so here's superior gluteal nerve. And because of the oppression of sex so early pain is not obvious local nerves began to appear, with the oppression of the passage of time, the symptoms gradually oppression, ischemia and hypoxia lead to dysfunction series syndrome causing low back pain. Therefore, the branch and the relationship between the starting point of the superior gluteal nerve, stroke, neural stem research. Methods: In this study, by the concentration of 10% formaldehyde solution perfusion fixed deal with the appearance of the conventional anti-corrosion were no limb '50 the body deformity China adult cadavers, 40 men, 10 women measured, measurement bilateral superior gluteal nerve length , width, thickness, and a branch, and so on. Results: 1. Superior gluteal nerve to 1-3 expenditures basin where a type accounted for 38%, the two type accounted for 52%, the three accounted for 10%. Length of the superior gluteal nerve, a type 1.39 ± 0.86cm, two type upper branch of 1.42 ± 0.71cm, the lower branch of 1.78 ± 0.83cm, the three upper branch of 1.31 ± 0.73cm, branch of 1.52 ± 0.61cm, the lower branch of 1.62 ± 0.72cm; superior gluteal nerve width, a 0.38 ± 0.08cm, two in the upper branch of 0.18 ± 0.09cm, the lower branch of 0.36 ± 0.03cm, seen two lower branch than the length of the upper branch compared significant difference p lt; 0.05; and three upper branch of 0.14 ± 0.08cm, charged to 0.14 ± 0.09 cm, the lower branch of 0.31 ± 0.07cm, three lower branch compared with the length of the upper branch significant difference p lt; 0.05; thickness of the superior gluteal nerve, a type of 0.003 ± 0.31cm, two type in the upper branch of 0.001 ± 0.31 cm inferior branch 0.002 ± 0.32cm, three upper branch of 0.001 ± 0.22cm, are expensed as 0.001 ± 0.32cm, the lower branch of 0.002 ± 0.32cm. 3 male superior gluteal nerve in the gluteal muscle branch, left, left outer, right, right outside the average count of 2.58 ± 0.21,5.49 ± 0.11,2.23 ± 0.21,6.65 ± 0.11 Zhi; hip little muscle left within , left outer, right, right outside the average count of 2.15 ± 0.18,2.36 ± 0.15,2.02 ± 0.01,2.62 ± 0.13 Zhi. Female superior gluteal nerve in the gluteal muscle branch, left, left outer, right, right outside the average count of 2.42 ± 0.12,6.02 ± 0.01,2.35 ± 0.25,6.78 ± 0.21 Zhi: hip little muscle left, left In addition, right side, right outside the average count of 2.31 ± 0.12,2.10 ± 0.16,2.23 ± 0.04,2.64 ± 0.02 Zhi. This shows the outside of the same sex in the number of branches to the gluteal muscles and hip little muscle and medial many and significant difference p lt; 0.05 4. Measuring the peripheral branches of the superior gluteal nerve to the midpoint of the upper edge of the greater trochanter Distance: male inside of the gluteal muscle average 5.78 ± 1.46cm, outside of an average of 6.01 ± was 1.26 cm. The hip medial average 5.49 ± 1.22cm, outside of average 5.48 ± 1.18cm. Female gluteal muscle medial average 5.29 ± 1.54cm, outside average 5.66 ± 1.36 cm. Hip medial average 4.33 ± 0.87cm, outside of an average of 4.42 ± 0.99cm. The distance from the midpoint of the upper edge of the inside to the outside of the peripheral branches of the same gender in the gluteal muscle to greater trochanter distance from the midpoint of the upper edge of the greater trochanter compared to the same sex significantly increased p lt; 0.05. surface positioning of the superior gluteal nerve in the buttocks: superior gluteal nerve at the piriformis position, concentrated in 3c grid, accounting for 68% of the total, the relative number mean, concentrated in the cell below the inner. The results suggest that: 1. Superior gluteal nerve endings points in the gluteal muscle medial, lateral, hip little muscle inside, outside there are peak, the highest peak to the outside of the gluteal muscle, the most significant. Observation of the morphology of the superior gluteal nerve endings position, the outside of the hip approach to better protect the superior gluteal nerve. Superior gluteal artery, vein and superior gluteal nerve access piriformis surface projection on the AC connection. Inferior gluteal nerve inferior branch below the projection of the body surface in between the large rotor tip or outside of the rotor most bumps, no obvious blood vessels and nerves of the distribution, and therefore can be seen here as a surgical approach to the safe area.
