abstract background: correction of severe kyphosis is a challenging operation in spinal surgery. a two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. we describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. methods: twelve patients (six male and si...

Background: Supracondylar fracture of the humerus is the second most common fracture in children. For most cases closed reduction and percutaneous crossed pinning is recommended. Those patients who had previously undergone an unsuccessful closed reduction trial need open reduction and pin fixation, but the best surgical approach is questionable. Most surgeons apply the technique of posterio...
