ABSTRACT

Objective: To establish a radiological measure parameter to classify the transverse apophysis length of 7th cervical vertebra. Material and methods: Millimetric measure with transparent ruler of transverse apophysis of 7th cervical vertebra on antero-posterior cervical radiography; classifying in: Hypotrophy, when the length was lesser of 2 Standard Deviation (SD); Normal length, equal to average like mean and no more than 2 SD; Hypertrophy, when length was more than 2 SD and less than 4 SD; Cervical rib when the length was upper than 4 SD. We examined 3,228 radiographys studies of patients, making 6,456 observations. Results: Sample age was 36 years average like mean, with 16-75 range; Gender distribution showed 2,098 females (65%) and 1,130 males (35%). The and SD of the sample was 13.51 mm ±3.97 on 6,456 observations; and DS was 12.54 mm ±3.82 in females and 15.10 mm ±3.51 in males patients. There was not difference between left and right sides in both genders; a difference of 2.5 mm. average like mean was observed in male gender more than in female patients. Conclusions : To asseverate that exists a cervical rib, the transverse apophysis of 7TH cervical vertebra must be more than 28 mm. of length in female gender and more than 29.5 mm in male gender.
