Rehabilitation Strategies in Management of Complex Case of Cervical Burst Fracture- A Case Report

A burst fracture is a descriptive term for an injury to the spine in which the vertebral body is severely compressed. They typically occur from severe trauma, such as a motor vehicle accident or a fall from a height. With a great deal of force vertically onto the spine, a vertebra may be crushed .If it is only crushed in the front part of the spine, it becomes wedge shaped and is called a compression fracture. However, if the vertebral body is crushed in all directions it is called a burst fracture. Burst fractures cause severe pain. The diagnosis of a burst fracture is usually made by x-rays and a CT scan. Occasionally, an MRI scan may be ordered as well, in order to assess the amount of soft tissue trauma, bleeding or ligament disruption. The review of the CT scan and x-rays allows the treating physician to make a determination as to the level of the fracture, whether it is a compression fracture, burst fracture or fracture dislocation. A spinal compression fracture also may be caused by trauma to the spine. Events that may cause trauma to the spine can include: A car accident, a hard fall or a fall from a height of more than 15 feet, landing on the feet, and a blow to the head. Any fall from a standing height that results in a spinal compression fracture or any other fracture most likely indicates weak bones due to osteoporosis. The physical exam should be performed to document both spinal deformity, that is, angulation of the spine or tenderness of the spine at the level of fracture, as well as, a neurologic exam. Neurologic exam should include testing of the muscle strength, sensation, and reflexes of the lower extremities, as well as, testing of bowel and bladder sphincter control. A 36 year old man was brought to the hospital as he had a fall from electric pole approximately 20 feet height. He had sustaining injury to the neck. Surgery was done as patient was diagnosed with C6 burst fracture with fracture dislocation of C5-C7. Therapeutic Interventions includes exercises, strengthening exercises, cervical fracture fixation, and traction.

The Hardware Failure and Correction Loss of Short-segment Pedicle Screw Fixation Combined With Transforaminal Interbody Fusion in Treatment of Unstable Thoracolumbar Burst Fracture: Retrospective Study in Vietnam

Background: Correction loss and hardware failure of short segment posterior pedicle screw fixation in treatment of thoracolumbar unstable burst fracture have been remaining a main concern. Several authors have introduced the procedures to solve these limitations including transforaminal interbody fusion (TIF). The purposes of this study were to evaluate the progressive kyphosis and implant failure of short-segment pedicle screw fixation combined with transforaminal interbody fusion in treatment of unstable thoracolumbar burst fracture.Methods: The retrospective study were enrolled in the patients with isolated unstable thoracolumbar burst fractures, Denis type IIB who were treated by posterior short fixation with TIF between January 2013 to January 2017. Patients were followed up for a minimum of one and half year. For evaluation of correction loss, % loss of anterior vertebral body heights (%AVB), vertebral kyphotic angle (VA) and regional kyphotic angle (RA) were collected preoperatively, postoperatively and at final follow-up. The hardware failure was assessed on radiological images at last follow-up. Results: There were 36 patients who met the inclusion criteria with a mean follow-up duration of 53 months. The mean correction loss of %AVB, VA and, RA were 10.2%, 2.9o and 5.6o, respectively. There were 6 patients (16.7%) with hardware failure at final follow-up. Conclusions: Short-segment posterior pedicle screw fixation with TIF using bone chip graft hasn’t prevented completely the hardware failure and progressive kyphosis in treatment of unstable thoracolumbar burst fracture.

Surgical versus non-surgical treatment for thoracolumbar burst fractures without neurological deficit: A systematic review and meta-analysis v1

The aim of this systematic review is to compare the outcomes of burst fracture between non-operative treatments and operative treatments.

Finite Element Analysis of a Novel Anterior Locking Plate for Thoracolumbar Burst Fracture

Purpose. The finite element analysis method was used to explore the biomechanical stability of a novel locking plate for thoracolumbar burst fracture fusion fixation. Methods. The thoracolumbar CT imaging data from a normal volunteer was imported into finite software to build a normal model and three different simulated surgical models (the traditional double-segment fixation model A, the novel double-segment fixation model B, and the novel single-segment fixation model C). An axial pressure (500 N) and a torque (10 Nm) were exerted on the end plate of T12 to simulate activity of the spine. We recorded the range of motion (ROM) and the maximum stress value of the simulated cages and internal fixations. Results. Model A has a larger ROM in all directions than model B (flexion 5.63%, extension 38.21%, left rotation 46.51%, right rotation 39.76%, left bending 9.45%, and right bending 11.45%). Model C also has a larger ROM in all directions than model B (flexion 555.63%, extension 51.42%, left rotation 56.98%, right rotation 55.42%, left bending 65.67%, and right bending 59.47%). The maximum stress of the cage in model A is smaller than that in model B except for the extension direction (flexion 96.81%, left rotation 175.96%, right rotation 265.73%, left bending 73.73%, and right bending 171.28%). The maximum stress value of the internal fixation in model A is greater than that in model B when models move in flexion (20.23%), extension (117.43%), and left rotation (21.34%). Conclusion. The novel locking plate has a smaller structure and better performance in biomechanical stability, which may be more compatible with minimally invasive spinal tubular technology.
