Radiological Evaluation of The Stability of Crossed-Pins Versus Lateral-Pins Fixation in Displaced Supracondylar Fractures of Humerus.
J Surg Pak Jan ;18(3):126-30.

Objective: To compare the radiological evaluation of stability of closed reduction of supracondylar fractures of humerus treated by percutaneous two-crossed-pin fixation and 2–lateral pin fixation. Study design: Randomized controlled trial. Place & Duration of study: Orthopedic Unit Hayatabad Medical Complex Peshawar, from January 2008 to July 2009. Methodology: Fifty patients with displaced supracondylar fracture of humerus presented between ages 1-12 year were randomly allocated in two groups of 25 patients each and were subjected to crossed-pin fixation and 2-lateral pin-fixation. Primary outcome measure was determined with the help of Baumann angle. Secondary outcome measure was determined with the help of Metaphyseal-Diaphyseal (MD) angle. Results: Mean age of patients was 7.02 ± 2.25 year. Mean loss of Baumann angle and MetaphysealDiaphyseal angles were 5.360 ± 2.220 and 2.420± 1.250 respectively. The mean Baumann angle loss in the two cross pins fixation group and the 2-lateral pins fixation group were 5.56 o ± 1.80 o and 5.16 o ± 2.64o respectively. The mean MD angle loss in the two crossed pins fixation group and the 2-lateral pins fixation group was 2.440± 1.220 and 2.400 ± 1.230 respectively. When loss of Baumann and Metaphyseal-Diaphyseal angles were compared between two methods of fixation using Student t test, no significant difference in the stability of two methods of pin fixation was observed. Conclusion: Radiological analysis showed that both the techniques were effective in terms of stability.
