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...

We report on the design and analysis of a controller that can achieve dynamical self-righting of our hexapedal robot, RHex. Motivated by the initial success of an empirically tuned controller, we present a feedback controller based on a saggital plane model of the robot. We also extend this controller to develop a hybrid pumping strategy that overcomes actuator torque limitations, resulting in ...

INTRODUCTION Intractable full-thickness rectal prolapse (IRP) unresponsive to conservative treatment remains a major problem after anorectoplasty for high or intermediate anorectal malformation (ARM). Surgical management must aim for a permanent fixation of the rectum to the presacral fascia. While in children with IRP following ARM repair the optimal procedure has not been established yet, lap...

PATIENTS The patient was first diagnosed as simple SIT with lumbosacral neoplasms according to the prenatal magnetic resonance imaging (MRI) examination; however, the local hospital ignored the important to physical examination so that missed anal atresia with fistula.
