Introduction: Diagnosis of Triplane fractures remains difficult in common practice. Aim of the study was the evaluation of the fracture pattern and the benefit of cross-sectional imaging in classification of Triplane-fractures., Material and Methods: A total of 27 pediatric patients treated for ankle fractures were identified from patient charts. Radiographic images of epiphyseal fractures (X-rays and additional cross-sectional imaging) were blinded evaluated by 13 observers to answer a specific questionnaire regarding type or fracture and treatment suggestion., Results: There were seven Triplane-I and eight Triplane-II fractures. The other physeal ankle fracture group consisted of four patients with a Twoplane-fracture, five Salter-and-Harris (SH) II, one SH-III, and two SH-IV fracture. Accuracy of classification improved considerably depending on the experience of the observer in pediatric trauma care. Surgeons specialized in pediatric trauma care classified correctly with conventional X-rays in 48.1 % of all cases presented versus 31.5 % appropriate diagnosis by younger fellows. Accuracy in exact specification of Triplane-fractures was comparable lesser in younger fellows (31.1 vs. 22 %). Cross-sectional imaging improved classification of all fractures in both groups (75.6 % specialized vs. 47.3 % non specialized). Whereas availability of cross-sectional imaging improved treatment recommendation in specialized surgeons this benefit was not detectable for the doctors without specialization. Evaluation of fracture pattern showed a relatively stereotypical fracture pattern in Triplane-II fractures, whereas Triplane-I fractures were more variable., Conclusion: The additional information of cross-sectional imaging seems helpful for any physician in finding the right classification of a pediatric ankle fracture. However, the additive information appears especially viable for experienced surgeons to suggest the appropriate treatment.

Purpose: Although there are currently many different strategies and recommendations in the therapy of cervical spine fractures in elderly patients, there are still no generally accepted treatment algorithms. The aim of the present study was to analyze the morbidity, mortality, and outcome of operated cervical spine injuries in the elderly., Methods: This study presents a retrospective review of 69 patients aged 65 years or older admitted to our level I trauma center with cervical spine injury, who had undergone surgical treatment. The data were acquired by analysis of the hospital inpatient enquiry system and radiological review., Results: The ratio between male and female patients was 37:32. The average age of the patients was 76 years (ranging from 65 to 96 years) for males and 80 years (ranging from 66 to 93 years) for females. Injury to the cervical spine was caused by low-energy trauma in 71 % and high-energy trauma in 29 %, respectively. 55.1 % sustained isolated cervical spine injuries, 39.1 % injuries to two adjacent vertebrae, 2.9 % injuries to three adjacent vertebrae, and 2.9 % an odontoid fracture combined with associated fracture(s) in non-contiguous vertebra(e). Isolated spine injury level was dominated by C2 (47.8 %). The most common site for injuries to two adjacent vertebrae was observed at C6/C7 (14.5 %). The morbidity included cerebral complications, respiratory complications, Clostridium difficile-associated disease, heart failure, and acute renal failure. Operative complications included dislocation/malposition, neurovascular lesions, wound infection, and transient swallowing difficulty. The mortality rate at 3 months was 26.1 %, with an in-hospital mortality of 21.7 %. Age was associated with mortality at 3 months. A cervical fracture-induced neurological deficit was documented in 26.1 %, resulting in a mortality of 44.4 % (8/18). Twenty-seven of 33 patients living at home/nursing home at the time of injury returned to their home/nursing home after their hospitalization. The overall outcome was predominantly related to age and the severity of neurological deficit., Conclusions: In elderly patients with cervical spine fractures, the hospital course is complicated by medical issues and early mortality rates are significant. Therefore, treatment strategies should be carefully individualized to the patients and their comorbidities.

Background: Therapy of vertebral fractures in the elderly is a growing challenge for surgeons. Within the last two decades, the use of polymethylmethacrylate (PMMA) in the treatment of osteoporotic vertebral fractures has been widely established. Besides vertebroplasty and kyphoplasty, the augmentation of pedicle screws with PMMA found widespread use to strengthen the implant-bone interface. Several studies showed an enhanced pullout strength of augmented screws compared to standard pedicle screws in osteoporotic bone models. To validate the clinical relevance, we analyzed postoperative radiologic follow-up data in regard to secondary loss of correction and loosening of pedicle screws in elderly patients., Materials and Methods: In this retrospective comparative study, 24 patients admitted to our level I trauma center were analyzed concerning screw loosening and secondary loss of correction following vertebral fracture and posterior instrumentation. Loss of correction was determined by the bisegmental Cobb angle and kyphosis angle of the fractured vertebra. Follow-up computed tomography (CT) scans were used to analyze the prevalence of clear zones around the pedicle screws as a sign of loosening., Results: In 15 patients (mean age 76 ± 9.3 years) with 117 PMMA-augmented pedicle screws, 4.3 % of screws showed signs of loosening, whereas in nine patients (mean age 75 ± 8.2 years) with 86 uncemented screws, the loosening rate was 62.8 %. Thus, PMMA-augmented pedicle screws showed a significantly lower loosening rate compared to regular pedicle screws. Loss of correction was minimal, despite poor bone quality. There was significantly less loss of correction in patients with augmented pedicle screws (1.1° ± 0.8°) as compared to patients without augmentation (5° ± 3.8°)., Conclusion: The reinforcement of pedicle screws using PMMA augmentation may be a viable option in the surgical treatment of spinal fractures in the elderly.

Background: Within the last two decades the use of polymethylmethacrylate (PMMA) in the treatment of osteoporotic vertebral fractures has been established widely. Several techniques of cement application in spinal surgery have been described. Besides classical vertebroplasty, kyphoplasty and related techniques that reinforce stability of the fractured vertebral body itself, augmentation of pedicle screws became an issue in the past 10 years. Aim of this technique is strengthening of the implant-bone-interface and the prevention of loosening and failure of posterior instrumentation in limited bone quality due to osteoporosis. PMMA use in spinal surgery always bears the risk of cement leakage and cement embolism. There are only few publications dealing with cement leakage in pedicle screw augmentation. We examined our cohort concerning incidence and type of leakage in comparison to the literature. In particular, we evaluated a possible role of intrathoracic pressure during cementation procedure., Patients and Methods: In this retrospective study 42 patients were included. Mean age was 74 (57-89) years. 311 fenestrated, augmented screws were analyzed postoperatively concerning leakage and subsequent pulmonary embolism of cement particles. Overall, there was a leakage rate of 38.3 %, and 28.6 % of patients showed pulmonary embolism of PMMA. During surgery, patients were in part ventilated with a positive end-expiratory pressure (PEEP) of 15 cmH2O during cement injection. These individuals showed significantly less leakage locally as well as less PMMA-emboli in the pulmonary circulation in contrast to patients ventilated without increased PEEP., Conclusion: PEEP elevation during administration of PMMA via fenestrated pedicle screws is reducing the leakage rate in spinal surgery. These beneficial effects warrant further evaluation in prospective studies.

Injuries to the spinal column and cord in children are a rare condition. Epidemiological data could help to establish an evidence-based assessment and therapy of these patients. We present a retrospective chart analysis of children with spinal injuries who were admitted to the emergency room. The patients were analyzed regarding age, mechanism, and distribution of their injuries to all spinal regions and treatment strategies. Thirty-five children met the inclusion criteria with severe spinal injuries (Abbreviated Injury Scale [AIS] for Region 6 [spine]; AIS region 6) in a period from January 2003 to December 2009. The incidence was extremely low in younger children, with increasing numbers during adolescence. Neurological deficit without fracture accounted for almost 25% of all patients. The majority of patients were treated conservatively; operative treatment was performed in 25% of patients with unstable fractures, particularly in adolescents. Treatment strategies differ according to the type and degree of injury, age, and level of spine maturation.

We report on a three-year-old girl who fell accidentally from the fourth floor. She suffered multiple trauma, including severe head injury, unstable T2-T3 Chance fracture, pneumothorax with lung contusion and serial rib fractures on the left side, liver laceration, splenic injury and fracture of the sacral bone on the right side. The progressive intracranial pressure was released by trepanation and bifrontal craniectomy. The abdominal injuries were treated conservatively. After stabilization of the intracranial situation, dorsal spondylodesis from T2 to T4 was performed employing the cannulated NEON system (Ulrich(®)) with CT-controlled positioning of guide wires. One year on, the implants have been removed and the patient has good function, with only a small atactic dysfunction as residuum. To our knowledge, this is the first report of a pediatric Chance fracture located in the upper thoracic spine following a fall from great height that describes how this treatment approach led to a very favorable outcome.

Injury to the spinal column and cord are often part of life-threatening multiple trauma. Epidemiological data could help to establish an evidence-based assessment and therapy of these patients. We present a retrospective chart analysis of 590 multiple traumatized patients admitted within a 4-year-period. Patients suffering from injuries of the spinal column were analysed regarding mechanism and distribution of their injuries to all body regions. Thirty-one percent (n = 183) of polytraumatized patients displayed a spine injury. Distribution analysis showed peaks in the cervical spine and the thoraco-lumbar junction. The risk of relevant associated injuries is mainly influenced from anatomical vicinity to the injured spinal segment. Injuries to the spinal column are frequent in the multiple trauma patients population. Diagnosed injuries to distinct body regions should make the trauma team suspicious of injury to the nearby spinal column. Appropriate treatment includes thorough assessment of all injuries to clarify the damage and carry on special protection of these spinal regions preventing from deterioration.

Treatment of polytrauma patients has been discussed extensively during the past decades. Management in the prehospital phase, on admission, and in the early postoperative/ICU-period has to refer to injury severity, priority of injuries, and likelihood of development of multi organ failure. Cervical spine injuries are reported in 4-34% of polytrauma cases. Securing the cervical spine by a hard collar is one of the basic procedures in the prehospital phase. Different strategies of assessing the cervical spine are still discussed controversially. Since plain radiographs, CT-scan, MRI, and flexion/extension fluoroscopy still play a role in early diagnosis of cervical spine injury, we present an analysis of cervical spine injuries in our multiple trauma patients to elucidate our algorithm. We reviewed our data between January 2003 and December 2006 concerning epidemiology, diagnosis and treatment of cervical spine injury in polytrauma patients. Multislice-CT (MSCT) or Multidetector-CT was used as standard diagnostic procedures in the polytraumatized patient. In 97% of patients, CT-scanning showed to be a reliable tool in detecting injuries of the cervical spine. Only in two patients (3%), additional MRI lead to a change in treatment strategy. Of 66 polytraumatized patients with significant cervical spine injury, 25 (37.9%) received surgical treatment within 24 h. Sixteen patients (24.2%) were treated surgically after stabilization on ICU. There was a better outcome concerning length of hospitalization in the "day-onesurgery" group. We consider MSCT as standard approach towards diagnosis of cervical spine injury in polytrauma patients. MRI and flexion/extension fluoroscopy can give additional information in selected cases.
