Pediatric Type III Supracondylar Humeral Fracture

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to compare pin configuration effects on early secondary displacement in the surgical treatment of pediatric supracondylar humeral fractures (SCHF).

Detailed Description
-----------------
The study consisted of 100 (68M, 32F) children who underwent surgery between 2010 and 2013 for Gartland Type 3 (SCHF). The patients divided into five groups according to the top in configurations (crossed 1 lateral 1 medial, crossed 2 lateral 1 medial, crossed 1 lateral 2 medial, 2 lateral divergent, and 3 lateral divergent). The average age at the time of injury was 7.34 (between 2 and 14 years). Bauman angle (BA), Humerocapital angle (HCA), Anterior humeral line (AHL), flexion range, extension range, and Carrying angle (CA) were compared at preoperative, postoperative 1st-day, postoperative last control, and non-operated side. The mean follow-up time 24,96±11,06 with a range of 12-54 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Baumann Angle | This angle is formed by the humeral axis and a straight line through the epiphyseal plate of the capitellum. Preoperative and postoperative angle differences are measured in anteroposterior and lateral X rays. These differences are measured for reduction quality and these parameters shows the success of the surgery. | postoperative 1. day, 1. month and 12. month | 
| Anterior Humeral Line | A line drawn down the anterior surface of the humerus should intersect the middle third of the capitellum. Preoperative and postoperative angle differences are measured in anteroposterior and lateral X rays. These differences are measured for reduction quality and these parameters shows the success of the surgery. | postoperative 1. day, 1. month and 12. month | 
| Humero-Capital Angle | On lateral X-ray angle between capitellum and humeral shaft. Preoperative and postoperative angle differences are measured in anteroposterior and lateral X rays. These differences are measured for reduction quality and these parameters shows the success of the surgery. | postoperative 1. day, 1. month and 12. month |
