Correlation between Bauman's and carrying angle in children with supracondylar fracture of humerus.

UNLABELLED Supracondylar fractures are the result of a fall on outstretched hand in more than 70% of cases, and more common in the non-dominant arm. Bauman's angle is used to determine the degree of displacement and angulation, and the quality of fracture reduction. Carrying angle is the clinical parameter ofvarus-valgus angulation with elbow fully extended and forearm completely supinated. PATIENTS AND METHODS The study was a retrospective-prospective and there were analyzed children under 14 years of age with supracondylar humerus fracture. They were analyzed by X-ray anteroposterior view of injured elbow, made before and after the surgery, with measuring Bauman's angle. Clinical examination was performed after completing physical therapy, when was measured carrying angle of the injured and healthy elbow using a goniometer. RESULTS AND DISCUSSION The results showed that there is a negative correlation Bauman and carrying angle of injured elbow (r = -0.543, p < 0.0001). Analyzing Bauman's angle deviation from value of 75 degrees and the loss of carrying angle there is noticed significant positive correlation between the Bauman angle deviation and loss of carrying angle. Bauman's angle correlates well with the carrying angle and can be used as an indicator of the potential cosmetic complications. CONCLUSION Carrying angle of uninjured elbow measured when reviewing a child who has suffered supracondylar fracture, can serve as a useful parameter in the assessment of real Bauman's angle, thereby the adequacy of fracture reduction on the injured arm.
