About

Humeral osteotomy is the most effective method for evident cubitus varus correction in children. Several osteotomy methods and fixation materials have been developed in the past. By applying the principles of deformity correction described by Paley, the investigators describe a novel corrective technique for cubitus varus involving lateral osteotomy using Kirschner wires.

Full description

Supracondylar humerus fractures (SHFs) account for approximately 10% of all pediatric fractures in children. Poorly treated SHFs can lead to the most common cubitus varus deformity especially in patients treated conservatively. The cosmetic aspect of this deformity is the main concern of patients, together with reduced remodeling ability. Inevitably, surgery is the first choice for such patients. Several osteotomy techniques and fixation materials have been developed in the last several decades. With the advent of three-dimensional printing techniques and computed tomography reconstruction methods, more accurate computing designs have been applied in the correction of cubitus varus. These techniques make the surgery more complex and require the performance of computed tomography (CT), resulting in high radiation exposure in children. Paley described the principles of deformity correction that are widely used for the lower limbs. These principles represent an alternative with easy application without the need of CT, with less occurrence of prominence and good cosmetic outcome. According to the Paley principles, all the vertex of the triangular osteotomy should site on the center of rotation of angulation (CORA) line, by doing this, the gun-butt deformity was corrected perfectly. More importantly, they help to accurately correct the anatomic axis of the upper limb. According to our knowledge, this is the first study describes the lateral closing wedge osteotomy for correction cubitus varus deformity in children by applying Paley's principles and fixation with K-wires. Taken together, the investigators aimed at verifying the feasibility of Paley's principles for deformity correction to treat cubitus varus in children.

lateral closing osteotomy for cubitus varus deformity
Description:
The osteotomy line of all patients was designed according to Paley's principles. The lateral incision was applied in all patients and the osteotomy lines were marked on the humerus with the assistance of C-arm radiographs.
Treatment:
Procedure: Paley's Principle osteotomy
