“Dorgan’s” Percutaneous Lateral Cross-Wiring of Supracondylar Fractures of the Humerus in Children

A comparative study of two percutaneous pinning techniques (Cross K wire vs Lateral K wire) for Gartland type III pediatric supracondylar fracture of the humerus

“…The advantage of medial-lateral entry pin fixation is probably increased biomechanical stability, although iatrogenic ulnar nerve injury may result from placement of the medial pin [2,4,7] . Conversely, the advantage of lateral entry pin fixation is avoidance of iatrogenic ulnar nerve injury, although the construct may be less stable biomechanically [2,[8][9][10] . The aim of this study was to compare the efficacy in terms of stability, functional outcome and iatrogenic ulnar nerve injury between lateral entry pin fixation and medial-lateral entry pin fixation of completely displaced (type-III) extension supracondylar fractures of the humerus in children.…”

A Comparative Study of Three Percutaneous Pinning Techniques for Paediatric Supracondylar Humeral Fractures

“…More recently, Lee et al (6) using a saw-bone model, found that two divergent lateral pins were comparable to cross-wires in extension, varus and valgus loading but were inferior in axial rotation testing. While Dorgan's technique does not include supporting biomechanical data, the crossed-wire configuration obtained by inserting both wires from the lateral side is similar to that obtained via the traditional medial and lateral technique (7,17). Stability of lateral parallel or divergent pinning is maximized (if perfectly done); by maximizing pin separation at the fracture site ( this is the key point of this procedure ) and adding a third pin in between ( if there is still significant motion), thus stabilizing all three columns.…”

“…Biomechanical studies have shown increased rotational stability for crossed-pin fixation but significant rates of ulnar nerve injury have been reported (4)(5)(6). To achieve fracture stability and avoid ulnar nerve injury, many options have been mentioned in the literature; including medial -lateral crossed pins, lateral crossed pins (Dorgan's technique) and lateral parallel or divergent pins (2,7).…”

Lateral Pinning for Supracondylar Humerus Fracture in Children: Does The Entry Point of the Pins have an Influence on the Outcome of the Fracture Fixation?

“…Several studies have tried to address the issue of lateral pin placement in the treatment of supracondylar fractures in children [4,6,7,8,[13][14][15][16][17][18] . Clinical studies have shown that double lateral pinning alone is of equal stability when compared with crossed pins for the majority of clinical fracture scenarios [6,12] .…”
