Objective  To explore the effectiveness of distal humeral dual-planar osteotomy followed with distal humeral lateral column anotomical locking plate fixation in the treatment of adult cubitus varus deformity combined with flexion restriction. Methods  The clinical data of 6 adult patients with cubitus varus deformity and flexion restriction treated with dual-planar osteotomy and internal fixation between April 2012 and September 2014 were reviewed. There were 3 males and 3 females with an average age of 22.2 years (range, 18-35 years). All the patients had history of elbow injury in childhood, the age being injured was 6.5 years on average (range, 2-13 years). There was no nerve injury, elbow strength weak, or unstable complications before admission. The preoperative elbow flexion was (107.50±5.24)°, elbow extension was (–12.17±3.48)°; the carring angle was (–19.50±4.46)°, the contralateral elbow carrying angle was (11.50±2.67)°; the length of humerus was (0.42±0.38) cm shorter than the unaffected humerus. The postoperative carrying angles, elbow flexion and extension, and humerus length were recorded. The modified Laupattarakasem criteria in which the comparison of bilateral elbow range of motion excluded was used to evaluate the results. Results  Primary healing of incision was got in all patients and there was no early postoperative complications. All the patients were followed up 19-27 months (mean, 20.8 months). During the follow-up, there was no complication such as loosening and breakage of the internal fixators and all fractures were healed within 3 months after operation. At last follow-up, the elbow flexion was (124.17±5.85)°, the elbow extension was (0.83±2.04)°, the carrying angle was (12.00±4.19)°, and the humerus shortening was (1.88±0.45) cm, all showing significant difference when compared with preoperative ones (t=–6.742, P=0.001; t=–11.068, P=0.000; t=–20.400, P=0.000; t=–13.914, P=0.000). According to the modified Laupattarakasem criteria, 1 case was excellent, 4 were good, and 1 was fair with an excellent and good rate of 83.3%. Conclusion  Normal carrying angle can be restored and elbow flexion can be increased by coronal closing wedge and sagittal trapezoid dual-planar osteotomy, single lateral anatomical locking plate fixation is available for early mobilization.
