[Comparative analysis of effectiveness of two single-pin internal fixation techniques in treatment of pediatric distal radial metaphyseal diaphyseal junction fractures].

Objective: To compare the effectiveness of two single-pin internal fixation techniques-trans-fracture in-out-in Kirschner wire fixation and antegrade elastic stable intramedullary nailing (ESIN) from the radial mid-shaft-in the treatment of distal radial metaphyseal diaphyseal junction (DRMDJ) fractures. Methods: >0.05), including age, cause of injury, affected side, presence of associated ulnar fracture, time from injury to surgery, or fracture classification. The operation time, intraoperative fluoroscopy frequency, fracture reduction rates on anteroposterior and lateral views, fracture healing time, and postoperative complications were recorded and compared. Clinical efficacy were evaluated at last follow-up using the Gartland-Werley scoring system. Results: >0.05). At last follow-up, according to the Gartland-Werley score, 24 cases were rated as excellent and 3 as good in group A, while 19 cases were excellent and 2 good in group B, yielding an excellent-good rate of 100% in both groups. Conclusion: Both fixation techniques achieved satisfactory effectiveness. However, the trans-fracture in-out-in Kirschner wire fixation technique is simpler to perform, requires shorter operation time and eliminates the need for implant removal, making it a potentially preferable option for treating this type of fracture.
