Mid-America Orthopaedic Association Physician in Training Award: Surgical Technique: Pediatric Supracondylar Humerus Fractures: A Technique to Aid Closed Reduction

Abstract

Background Anatomic reduction of some displaced pediatric supracondylar humerus fractures is not attainable via closed manipulation, thus necessitating open reduction. Open reduction has been associated with increased complications, including elbow stiffness, scarring, iatrogenic neurovascular injury, and longer hospital stays. Using a Schanz pin to aid in closed reduction may decrease the need for conversion to an open procedure, possibly reducing morbidity. Description of Technique A percutaneously placed 2.5-mm Schanz pin was drilled into the posterior humeral diaphysis and used as a joystick to reduce anterior and posterior, varus and valgus, and rotational deformity. The fracture then was stabilized with 0.62-mm K-wires placed under fluoroscopy and the Schanz pin then was removed. Methods We retrospectively reviewed all displaced pediatric supracondylar humerus fractures treated by one surgeon from March 2002 through December 2010, with 143 fractures meeting criteria for inclusion. These fractures then were divided into two groups. Group 1 (90 fractures) included fractures treated before implantation of the Schanz pin. In this group, if successful reduction could not be achieved via closed manipulations, a formal open reduction was performed. In Group 2, (53 fractures) the Schanz pin technique was used to assist with reduction of fractures that were not reduced successfully by closed manipulations. All fractures were stabilized with the 0.62-mm K-wires after the reductions. To equalize group size, the 37 most remote fractures in Group 1 were removed, leaving a final 53 fractures in each group for analysis. Demographics, injury data, operative technique, complications, and radiographic reduction were analyzed. The minimum followup for both groups was 3.3 weeks (average, 13 weeks; range, 3.3-130 weeks). Results Fewer fractures in Group 2 (one of 53, 1.9%) compared with Group 1 (seven of 53, 13%) underwent open reduction. Ten fractures in Group 2 underwent the Schanz pin technique, and none of these had open reductions. We found no difference between the groups concerning fracture alignment at final followup or postoperative complications.

“…[7,8,9] Complications were usually associated with open reduction ; therefore, closed reduction with Kirschner wire percutaneous internal xation was generally accepted as the optimal approach. [10][11][12][13][14].…”

Letter to the Editor: Mid-America Orthopaedic Association Physician in Training Award: Surgical Technique: Pediatric Supracondylar Humerus Fractures: A Technique to Aid Closed Reduction

“…We read the article by Herzog et al [1] with great interest. We found the study interesting because the technique described by the authors is similar to our previously published article [2], referred by the authors in the Introduction and Discussion sections of their study.…”
