Management of Neglected Lateral Condyle Fracture of Humerus: A Comparison between Two Modalities of Fixation.

Background: Implant for fixation of neglected fracture lateral condyle humerus remains an issue of controversy. This study compares the clinical and radiological outcome of fixation with Kirschner wire (K-wire) and with cancellous screw (CS) in neglected fracture lateral condyle humerus.

Materials and Methods: 42 patients of neglected lateral condyle humerus fracture, treated either by open reduction and internal fixation (ORIF) with K-wire or ORIF with CS were included in study. The comparisons were made in term of slab immobilization time, union time, improved range of motion (ROM), final achieved carrying angle, and functional outcome measured by Liverpool Elbow Score (LES).

Results: There were 22 patients in Group I with mean age 7.8 years and 20 patients in Group II with mean age 7.3 years. Mean delay in presentation was 12.9 versus 15.6 weeks ( P > 0.05). Mean followup was 26.9 versus 26.7 months. Mean duration of immobilization was 11.6 versus 9.4 weeks ( P < 0.001). Improved carrying angle was 6.8° versus 9.7° ( P < 0.05). Mean gain in ROM was 17.7° versus 27.5° ( P < 0.05). Mean LES was 8.15 versus 8.18 ( P > 0.05). Premature closure of physis was observed in two patients. Pin tract infection was seen in three of Group I ( P > 0.05).

Conclusion: There was no difference in LES, irrespective of implant used. Screw was better in terms of duration of slab, improvement in carrying angle and ROM.
