1/16. Fracture-dislocations of the sacrum. Report of three cases.

    The pattern of fracture-dislocation of the upper part of the sacrum is demonstrated in three patients. The fracture line followed the segmental form of the sacrum and was usually caused by a posterior force against the pelvis which had been locked by hip flexion and knee extension. Fractures of the lumbar transverse processes also occurred, presumably from avulsion by the quadratus lumborum muscle. The damage to the sacral plexus found in all three cases recovered after several months. Radiographs of the injury are difficult to obtain in severely injured patients but oblique views of the sacrum help to determine the extent of the forward dislocation.

2/16. Fracture-dislocation of the lumbosacral spine: case report and review of the literature.

    This report describes an extensively comminuted fracture of the sacrum and the L-5 vertebral body with complete anterior dislocation of the lumbar spine on the sacrum that occurred in a 19-year-old man ejected from a motor vehicle. Lumbosacral dissociation was characterized by computed tomography with three-dimensional and multiplanar reconstruction, and definitively managed by posterior instrumentation using locking hook spinal rods attached to the pelvis with hockey stick attachments by the Galveston technique. Implications of this case and a review of the literature are presented.

3/16. Traumatic lateral lumbosacral dislocation: one case and review of literature.

    OBJECTIVE: Lateral traumatic lumbosacral dislocation is a rare and severe lesion of the lumbosacral junction. Only one case has been reported in the literature. We report a new case of pure lateral lumbosacral dislocation. methods: A 27-year-old man had an isolated pure lateral traumatic dislocation of the lumbosacral junction after a motorcycle accident. The diagnosis and the therapeutic course are analyzed and discussed. RESULTS: Traumatic lumbosacral dislocation usually occurs in patient with multiple traumas. Generally, in the case of complete fracture-dislocation, on lateral radiographs one can observe the L5 vertebra slippage over the sacrum, resulting from an associated severe disc disruption. This feature was not seen in our patient. Surgical treatment consisted of an open reduction of the dislocation, stabilization with posterior instrumentation, and a lumbosacral arthrodesis by posterolateral grafting. In cases of pure lateral dislocation, short instrumentation can be recommended, extending from L5 to S1. Addition of an interbody fusion should be considered when the L5-S1 disc is disrupted, which is responsible for the anterior slippage of L5 over S1. Disc disruption can be evoked on preoperative magnetic resonance imaging (MRI) and intraoperatively by exploring the spinal canal. CONCLUSIONS: Pure lumbosacral dislocation with a lateral translation seemed to have no disc disruption as observed in complete fracture dislocation. Nevertheless, we recommend looking for an L5-S1 disc disruption either on preoperative MRI or during surgical exploration.

4/16. Unilateral lumbosacral facet joint dislocation associated with vertical shear sacral fracture.

    An 18-year-old woman involved in a motor vehicle accident sustained a vertical shear fracture of the sacrum accompanied by unilateral dislocation of the L5-S1 joint. Evaluation of the patient's injuries was defined by computed axial tomography. Through a posterior midline incision, open reductions of the dislocated L5-S1 joint and of the sacral fracture were performed. Reduction was followed by anterior stabilization of the symphysis pubis. The patient remained neurologically intact after surgery.

5/16. Bilateral fracture-dislocation of the sacrum.

    The authors describe a semiconservative approach for bilateral fracture-dislocation of the sacrum, an extremely rare injury. traction is advocated; it seems to lead to a good functional result after 20 years. Other authors either propose internal fixation or benign neglect, also with a good outcome. Every case must be approached on an individual base.

6/16. Bilateral fracture-dislocation of the sacroiliac joint: a case report.

    Bilateral fracture-dislocation of the sacroiliac joint with intrapelvic displacement of the sacrum is a rare and extremely severe injury. We treated a patient with bilateral fracture-dislocation of the sacroiliac joint using a nonoperative method and obtained an excellent functional result.

7/16. Bilateral sacroiliac joint fracture-dislocation: a case report.

    Bilateral sacroiliac joint fracture-dislocation of the sacrum with displacement is a rare injury. We found only four such injuries previously reported in the literature. Nonoperative management in this case led to complete functional return and acceptable alignment.

8/16. Lateral lumbosacral fracture dislocation: a case report.

    A case of lateral fracture dislocation of the fifth lumbar vertebra on the sacrum successfully treated by open reduction is described. The literature of this injury is reviewed.

9/16. Treatment of painful long-standing displaced fracture-dislocations of the sacrum. A case report.

    A 19-year-old white man sustained multiple injuries, including a severely displaced Malgaigne fracture. Secondary uncontrollable hemorrhage was treated successfully by arterial embolization. The patient retained a painfully displaced right sacroiliac joint. His multiple injuries resolved symptom free with the exception of the right sacroiliac region. An attempt to reduce the dislocation by an extensive soft tissue release and skeletal traction was unsuccessful. Solid fusion of the L4 and L5 vertebrae to the ilium significantly reduced the patient's pain. Painful, long-standing severely displaced Malgaigne fracture can be successfully treated by sacroiliac arthrodesis without reduction.

10/16. Traumatic lumbosacral dislocation in a 5-year-old boy with eight years follow-up.

    STUDY DESIGN. The authors present an unusual case of pure traumatic bilateral lumbosacral dislocation in a 5-year-old boy, the conservative treatment carried out, and the long-term result. OBJECTIVES. To describe a rare traumatic lesion in children and evaluate the result obtained with conservative treatment. SUMMARY OF BACKGROUND DATA. Watson-Jones was the first to describe this type of lesion. Since then, only a few cases have been added. Most authors suggest that open reduction should be carried out. No cases of this type of injury in children have been reported. methods. A 5-year-old boy was hit in the lumbosacral region with a rocking chair. Examination showed neurologic deficit of left L5 and S1 nerve roots. Roentgenographic examination and computed tomography scan confirmed the anterior dislocation of the fifth lumbar vertebra on the sacrum without any fracture. He was treated with traction, followed by hyperextension in a Cotrel traction table and further immobilization with a lumbar plaster jacket. RESULTS. Eight years after the injury, the patient had no neurologic deficit and lumbar radiographs showed a good alignment of the lumbosacral spine. CONCLUSION. In children with traumatic lumbosacral dislocation, closed reduction should be attempted even if neurologic deficit is present.
