Comparative evaluation of pedicular screw fixation and hartshill ring in dorsolumbar spinal injuries

Introduction: The dorso lumbar segment of spine (D10 to L2) is an unstable between fixed dorsal and mobile lumbar spine. The Hartshill rectangle fixation is a modification spinal instrumentation fixation. The rectangle formed allows it to fit snugly against the lamina and provides good rotational stability. While Pedicle screw instrumentation also place instrumentation within the spinal canal thus lessens the risk of neural injury. Aim: Is to comparative evaluation of pedicular screw fixation and hartshill ring in dorsolumbar spinal injuries in terms of stability, functional outcome and postoperative complications. Materials and method: Total no of patients was 50 (25 each). Conclusion: Hartshill ring fixation is safe and simpler method, however pedicular screw fixation require more instruments, but it is more firm and and stable fixation.
