Comparison of closed reduction and percutaneous pinning versus open reduction and percutaneous pinning in displaced supracondylar fractures of the humerus in children.
A retrospective review of 29 children with displaced supracondylar humerus fractures was performed. Fifteen patients treated with closed reduction and percutaneous pinning and 14 patients treated with open reduction and percutaneous pinning were evaluated at a minimum of 18 months (range 18-80 months). Results were graded according to the criteria of Flynn et al. (Flynn JC, Matthews JG, Benoit RL: Blind pinning of displaced supracondylar fractures of the humerus in children. J Bone Joint Surg [Am] 56:263-272, 1974) using both cosmetic and functional evaluations. Excellent or good results were obtained in 14 of the 15 fractures treated with closed reduction and percutaneous pinning and in 12 of the 14 fractures treated with open reduction and percutaneous pinning. The three fair cosmetic results were associated with inadequate reduction and residual medial angulation. Ten to 15 degrees of motion loss occurred in three older patients. One patient in each group had a minor pintract infection. There were no cases of iatrogenic nerve injury or myositis ossificans. The treatment goal in displaced supracondylar humerus fractures in children is anatomic reduction. If an anatomic reduction cannot be achieved with closed reduction, open reduction is indicated. This can be done without an increased risk of complications.
