ABSTRACT

BACKGROUND AND OBJECTIVES: Nerve block or neurolysis is an important approach in the treatment of spastic equinovarus foot. To illustrate the accurate location of the nerve branch to the tibialis posterior muscle (TP) in clinical practice, 21 adult cadavers were dissected and 14 complete both lower limb specimens were obtained. A total of 28 lower limbs were included. METHODS: We measured the length of the motor branch nerve (LM) of the tibialis posterior muscle, the length of the fibula (LF), the vertical distance (D1) from the midpoint of LM to the fibula tip as well as the horizontal distance (D2) from the midpoint of LM to the inner edge of the fibula. RESULTS: The LM was higher (35.74 ± 7.28 mm) in male than in female (30.40 ± 6.88 mm) specimens but there was no significant correlation between LM and gender (p > 0.05). Additionally, among male specimens, the LM on the right side was longer than that on the left (p ≤ 0.05) while among female specimens, the D1 on the left side was longer than that on the right (p ≤ 0.05). The LF in male specimen was significantly longer than that in female (p ≤ 0.05). The midpoint of the nerve to the motor branch of the tibialis posterior muscle was about 50 mm distal to the fibular head and 10 mm at the inner edge of the fibula. CONCLUSION: Using this coordinate, the midpoint of the nerve branch to the TP could be accurately located.

ABSTRACT

Recent case-control studies have identified some loci that are associated with rheumatoid arthritis (RA). Among these, a single nucleotide polymorphism (SNP), Gly307Ser (rs763361), in the CD226 gene was first discovered to confer the risk of RA in populations with European and Colombian ancestry. Because the effect of genetic factors varies in different races, the association between RA and CD226 is yet to be evaluated in other non-European populations. Here, we report the significant association between CD226 and RA in a Chinese population of 423 randomly enrolled individuals. The statistical results show that the rs763361 SNP in the CD226 gene is significantly associated with RA in the Chinese population group (P (obs) = 0.005, odds ratio = 1.52). After adjusting for sex and age using multivariate logistics regression analysis, the association is still positive (P (adj) = 0.029, odds ratio = 1.45). Meta-analysis confirms the association between rs763361 and RA (overall P < 0.001, overall odds ratio = 1.12). The test of odds ratio heterogeneity also suggests that the rs763361 SNP confers the same risk of RA in both the Chinese and the Colombian populations, and indicates that rs763361 may play a more important role in non-European populations compared with the European population (P = 0.031). These results demonstrate a genetic association between the CD226 gene and RA in a Chinese Han population with a potentially greater genetic effect than in the European population.
