Abstract
Aims: To correct cubitus varus deformity by wedge resection and compression by external þxator for rapid osteogenesis. Methods: We treated 6patients with cubitus varus deformity secondary to malunited supra-condylar fracture of humerus. 4:M, 2:F aged between 8–14years. Duration between injury and surgery averaged 20months (1.4–2.4years). Preoperative humeroulna angle on x-ray averaged Ð18.5¡ (−12¡ to −28¡) and on contralateral limb averaged 12.4¡ (8¡−18¡). All patients had full elbow movements preoperatively. 2x2mm k-wires passed in lower humeral metaphysis parallel to joint line and 2x2mm k-wires passed in lower diaphysis perpendicular to humeral shaft. Laterally based bone wedge equivalent to preoperatively calculated template including 5¡ of over-correction was removed in between the wires. A compression distraction rod was applied to close the wedge by compression. Elbow was mobilized after postoperative pain relief in þrst week with dynamic elastic sling. Fixator was removed at 6weeks. Results: All patients achieved full elbow movements and complete cosmetic correction. Osteotomy united faster under compression. No neurovascular complication was seen. One patient had minor pin tract infection, subsided on treatment. Conclusions: Any residual corrections postoperatively are fully adjustable. Literature reports poor results of up to 30% due to loss off or inadequate correction. Stability achieved by þxator allowed early postoperative elbow mobilization. Extremely reliable, ßexible and fully controlled method.
