Abstract:

BACKGROUND: In recent years, the incidence of cervical spondylosis is increased in the young. However, previous studies regarding cervical spinous morphology have been conducted in adults.
OBJECTIVE: To explore the morphological characteristics of juvenile cervical spinous process.
METHODS: In original complete specimens of cervical vertebra of adolescents aged 14 to 19 years, the spinous process bifurcation on the length, angle, and the incidence, type and other morphological features of gross anatomy were observed. And the results were compared with adult dehydration specimens.
RESULTS AND CONCLUSION: Young C2-C6 spinous process bifurcation length was (7.73 ± 1.82), (5.33 ± 1.43), (5.62 ± 1.57), (5.22 ± 1.99) and (5.36 ± 0.98) mm, respectively; bifurcation incidence rate was 100.0%, 80.0%, 73.3%, 80.0% and 46.7%, respectively, of which the highest rate occurred in C2 bifurcation, and the bifurcation was significantly different between C2 and other segments (P < 0.05), but there was no bifurcation in C7. Bifurcation angle ranged from C2-C6 was (63.07 ± 26.00)°, (70.42 ± 31.43)°, (84.09 ± 31.51)°, (46.17 ± 16.78)°, (59.00 ± 16.90)°. The shape of the end was inverted "U" or "V" shaped, and some was M-typed. The basic morphological characteristics and above parameters of spinous process were consistent with the adult control group. Results showed that C2 and C7 spinous process morphology of adolescents aged 14 to 19 years was similar to the adults, and can be used as location marks of neck massage, Chinese medicine therapy and surgery.
