Evolução etária do ângulo de carregamento do cotovelo: estudo clínico-radiográfico

Abstract

Objective: This paper has the purpose of evaluate the elbow carrying angle by clinic and radiographic examination in normal children and determine the range of normality according to age from childhood to skeletal maturity and also check if there is a statistically significant difference between the clinical and radiographic measurements. Methods: We evaluated 510 persons with ages varying from 1 to 18 years distributed in groups with 30 subjects according to the age group with 1-year interval. We performed radiographic examination of the elbow and measured the angle formed by the long axis of the humerus and ulna. The data were statistically analyzed using the student t-test. Results: We determined a normal curve of the study population where there was an increase of this parameter with the progression of age. No statistically significant difference between the clinical and radiographic measures. Conclusion: The average of the elbow carrying angle was 12,78 ± 5,35 degrees for females and 11,20 ± 4,45 degrees for males. This values increase progressively from childhood until 16 years when we notice stabilization. There was no statistical difference between the clinical and radiographic measurements.

A Comparative Study of the Modified Baumann’s Angle Between the Dominant and Non-Dominant Sides in a North Indian Pediatric Population

“…No statistically significant distinction was observed between the clinical and radiological carrying angles, which coincides with the results reported by Terra et al [ 15 ]. Therefore, it may be inferred that a comprehensive clinical measurement is equally effective as a radiograph in giving adequate information for assessing the carrying angle of the elbow.…”

Radiological study of carrying angle among male and female and its clinical importance

“…Our study is invariable on the sides of the upper limb. Bernardo Barellos and Terra et al 14 stated that the carrying angle physiologically increases as age progresses. The angle gradually increases from childhood to sixteen years of age.…”

Variation in carrying angle - A normative study

“…The arrow on the goniometer measurement plate indicates the angle (Balasubramanian et al, 2006). 7 Measurement of height of the sample was taken using an inch tape. Height was measured from vertex to heel of the individual with bare foot in anatomical position in centimeters.…”

“…The carrying angle's pathophysiology can be influenced by factors such as elbow joint overextension, gender, age, and anthropometric parameters like the distance between the trochanters and height. It can also be affected by traumatic injuries, fractures, ligamentous laxity, congenital deformities, rheumatic or inflammatory diseases, and hereditary conditions (Terra et al, 2011). 7 Significant differences in carrying angles between the left and right sides can also occur.…”
