SUPRACONDYLAR FRACTURE OF HUMERUS;

RADIOLOGICAL ASSESSMENT OF CLOSED REDUCTION BY BAUMANN ANGLE

Abstract

Objectives: To assess closed reduction by Baumann angle in supracondylar fractures humerus treated by closed reduction and
percutaneous pinning. Material and Methods: This prospective study of 50 patients who presented with displaced supracondylar fracture of
humerus in children between ages 1-12 years were admitted to Orthopedic and Trauma unit of Hayatabad Medical Complex Peshawar over
period from January 2008 to July 2009. Closed reduction and percutaneous pinning were performed under general anesthesia and postoperative
reduction was assessed by Baumann angle. All patients were followed for one year. Results: Mean age of the patients was 7.02 years
± 2.25 SD. Loss of Baumann angle in injured side was range from 2O to 8O. Loss of carrying angle in injured side was range from 3O to 9O. When
Baumann angle and carrying angle of both sides were compared the mean Baumann angle loss and carrying angle loss were 5.360 ± 2.22 SD
and 4.320 ± 1.52 SD respectively. Using Flynn’s criteria 36 (72%) patients out of 50 patients with carrying-angle loss considered to be excellent
results and 14(28%) good results. Neither of the patient developed cubitus varus deformit y after one year of follow-up. Conclusions: Baumann
angle of the humerus is a simple and reliable measurement of closed reduction that can be used to predict final carrying angle in supracondylar
humeral fractures in children.
