PEDIATRIC ORTHOPAEDICS
A comparative study of two closed reduction methods for pediatric supracondylar humeral fractures
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2018;6(9):9 J Orthop Sci. 2016 Sep;21(5):609-1368 pediatric patients with displaced supracondylar humeral fractures were randomized to one of two methods of closed reduction. In one group, if closed manipulation did not yield acceptable reduction, the joystick technique was used to facilitate reduction. In the other group, only manual traction was used for reduction. Once reduction was achieved, all patients received fracture fixation with percutaneous pinning. Results demonstrated a significantly shorter operative time, shorter fluoroscopy time, and higher reduction success rate in the joystick group compared to the manual traction group. The time to union, final radiographic outcome, and the clinical outcome did not significantly differ between groups.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか?
Supracondylar humeral fractures are a relatively common childhood injury, usually resulting from a fall. Many of these fractures require fixation, most commonly using percutaneous pinning. Obtaining an adequate closed reduction of the fracture can be challenging with many cases converted to open reduction following failed attempts at closed reduction. The joystick technique, using either a Kirschner wire or a Shanz pin, has been reported to aid reduction, though whether there is any significant advantage of this technique over manual traction in obtaining reduction has yet to be tested in a randomized controlled trial.
主な研究課題は何ですか?
In the closed reduction of pediatric supracondylar humeral fractures, is there a significant difference in operative outcomes, including operative time, fluoroscopy time, reduction success, and postoperative radiographic outcome between reduction by joystick technique versus traditional manual traction?
重要な知見は?
- Operative time was significantly shorter in the joystick group (30.5+/-9.0min) compared to the manual traction group (48.2+/-16.4min) (p=0.000).
- Fluoroscopy time was significantly shorter in the joystick group (25.4+/-10.5s) compared to the manual traction group (55.0+/-21.2s) (p=0.000).
- The rate of failed intraoperative reduction was significantly lower in the joystick group (0/34) compared to the manual traction group (9/25) (p=0.004).
- No significant difference in the length of hospital stay was observed between the joystick group (3.0+/-1.5 days) and the manual traction group (3.2+/-1.3 days). (p=0.595).
- Time to union did not significantly differ between the joystick group (5.8+/-1.5 weeks) and the manual traction group (5.6+/-1.6 weeks) (p=0.625). Malunion occurred in four patients from each group. Nonunion was not observed in any patient in either group.
- Pin-tract infection occurred in three patients in the joystick group and two patients in the manual traction group. No other complications occurred.
- No significant difference in Flynn elbow score at final follow-up was observed between groups (p=0.664).
最も覚えておくべきことは?
In the closed reduction and percutaneous pinning of pediatric supracondylar humeral fractures, closed reduction via the joystick technique significantly reduced operative time, fluoroscopy time, and improved the success rate when compared to reduction via manual traction. No significant differences in postoperative radiographic or clinical outcome were noted.
それが私の患者ケアにどのように影響するか?
The results of this study suggest that closed reduction with the joystick technique in percutaneous pinning of pediatric supracondylar humeral fractures may improve operative efficiency when compared to only attempting with standard manual traction. Additionally, the joystick technique for fracture reduction did not have a negative impact on the postoperative radiographic and clinical outcome when evaluated over a 2-year follow-up. Nevertheless, the current results are limited in strength by the small sample size, with large multi-center trials needed to verify these findings and further evaluate potential complications or the joystick technique.
