ABSTRACT
Fusion is one of the most commonly performed spinal procedures, indicated for a wide range of spinal problems. Elimination of motion though results in accelerated degeneration of the adjacent level, known as adjacent level disease. Motion preservation surgical methods were developed in order to overcome this complication. These methods include total disc replacement, laminoplasty, interspinous implants and dynamic posterior stabilization systems. The initial enthusiasm about these methods was followed by certain concerns about their clinical usefulness and their results. The main indications for total disc replacement are degenerative disc disease, but the numerous contraindications for this method make it difficult to find the right candidate. Application of interspinous implants has shown good results in patients with spinal stenosis, but a more precise definition is needed regarding the severity of spinal stenosis up to which these implants can be used. Laminoplasty has several advantages and less complications compared to fusion and laminectomy in patients with cervical myelopathy/radiculopathy. Dynamic posterior stabilization could replace conventional fusion in certain cases, but also in this case the results are successful only in mild to moderate cases.

Study Design Case report. Objective Sacral fractures, traumatic or atraumatic, are a rather rare cause of low back pain. The majority of the cases of pregnancy-related sacral fractures are reported as a postpartum complication, and only few cases of sacral atraumatic fractures have been reported in the last trimester of the pregnancy. The aim of this study is to report a rare case of atraumatic sacral fracture in the third trimester of pregnancy. Methods We report the case of a 30-year-old Caucasian European woman during her 37th week (36 weeks and 4 days) of gestation, who complained during her scheduled obstetric examination of continuous low back pain with no associated history of trauma. The patient performed activities of daily living with a normal level of fatigue and reported no running or walking long distances. She was examined in our department, and a magnetic resonance imaging scan was performed that showed a vertical nondisplaced fracture in her left sacrum. Results The patient was treated conservatively, and analgesics were administrated according to the consensus of the orthopedic and the anesthesiology departments. No further complications were recognized in the remaining period of her pregnancy, and a healthy child was born by caesarean section. Conclusions Atraumatic fractures of the sacrum should be included in the differentiated diagnosis of pregnant patients with low back pain.
ABSTRACT
Study Design Case report. Objective The purpose of the present case report was to present a patient with a history of ankylosing spondylitis who sustained a dislocation of C6 on C7 and died soon after his presentation in the emergency room (ER). Methods An 88-year-old man was brought to the ER due to a neck injury secondary to a fall. Imaging of the cervical spine revealed anterior dislocation of C6 on C7 and the characteristic "bamboo" spine of ankylosing spondylitis. Results The patient died within 30 minutes due to respiratory insufficiency. Conclusion Isolated cervical spine injuries in patients with ankylosing spondylitis can be fatal. A high degree of clinical suspicion, thorough imaging with computed tomography, and meticulous handling are required in this patient population.
