Due to increasing life expectancy, the prevalence of fractures caused by osteoporosis is raising. These fractures significantly reduce the quality of life in the elderly population. They represent both a disease and an injury simultaneously. While they were once treated solely with conservative methods, new techniques and implants are expanding the indications for surgical treatment. This article presents the current treatment options.

Introduction: Thoracolumbar spine injuries can result from various traumatic events such as falls, motor vehicle accidents, and sports injuries. While surgical intervention is often indicated for complex fractures and in case of neurological deficits, non-operative treatment remains a viable option for certain types of injuries. Aims: This manuscript aims to provide a comprehensive overview of the specific indications and treatment options of non-operative thoracolumbar spine injuries. It seeks to provide evidence-based recommendations for selecting patients suitable for conservative management based on fracture type and stability, absence of neurological deficits, spine deformity, integrity of the posterior ligament complex and patient specific factors.

Acute traumatic spinal cord injury (tSCI) is a complex and heterogeneous injury, where the level of injury, injury severity, duration and degree of spinal cord compression, and blood pressure management seem to influence neurologic outcome. Although data in the literature seem to be inconsistent regarding the effectiveness of surgical decompression and spinal fixation in patients with thoracic and thoracolumbar tSCI, some single-center studies suggest that early surgical decompression may lead to a superior neurologic outcome, especially in patients with incomplete tSCI, suggesting surgical decompression to be performed as soon as possible. However, high energy injuries, especially to the upper thoracic levels, may be too severe to be influenced by surgical decompression, which may represent a critical second hit for the polytraumatized patient. Therefore, the surgeon first needs to critically evaluate the potential for neurologic recovery in each patient before determining the ideal timing of surgery. Circulatory stabilization must be achieved before surgical intervention, and minimally invasive procedures should be preferred. Invasive blood pressure monitoring should be started on admission, and maintenance of a MAP between 85 and 90 mmHg is recommended for a duration of 5–7 days, with special attention to the prevention of hypoxia, fever, acidosis and deep venous thrombosis. The role of a 24-hour infusion of high-dose MPSS is still controversial, but it may be offered at the discretion of the treating surgeon to adult patients within 8 h of acute tSCI as a treatment option, especially in the case of very early decompression or incomplete tSCI.

The operative treatment of thoracolumbar fractures is a rapidly evolving improvement in the care of patients with this injury after trauma. This article describes the different techniques and principles. Considerations and methods of treatment are scientifically addressed and illustrated according to the classification and severity of the fracture pattern. The use of computer navigation and optimisation of minimally invasive techniques is inevitable. The timing of surgery as well the removal of the material after fracture healing are also discussed. The operative treatment of spinal fractures is emerging and there is still much more knowledge to gain. [ABSTRACT FROM AUTHOR]

Background: Instrumentation of the pediatric spine is challenging due to anatomical constraints and the absence of specific instrumentation, which may result in iatrogenic injury and implant failure, especially in occipito-cervical constructs. Therefore, preoperative planning and in vitro testing of instrumentation may be necessary. Methods: In this paper, we present a technical note on the use of 1:1 scale patient-specific 3D printed spinal models for preoperative assessment of feasibility of spinal instrumentation with conventional spinal implants in pediatric spinal pathologies. Results: The printed 3D models fully matched the intraoperative anatomy and allowed a preoperative confirmation of the feasibility of the planned instrumentation with conventional screws for adult patients. In addition, the possibility of intraoperative model assessment resulted in better intraoperative sense of spinal anatomy and easier freehand screw insertion, thereby reducing the potential for iatrogenic injury. All 3D models were printed at the surgical department at a very low cost, and the direct communication between the surgeon and the dedicated specialist allowed for multiple models or special spinal segments to be printed for more detailed consideration. Conclusions: Our technical note highlights the critical steps for preoperative virtual planning and in vitro testing of spinal instrumentation on patient-specific 3D printed models at 1:1 scale. The simple and affordable method helps to better visualize pediatric spinal anatomy and confirm the suitability of preplanned conventional spinal instrumentation, thereby reducing X-ray exposure and intraoperative complications in freehand screw insertion without navigation.

Introduction: In the case of tumor resection in the upper cervical spine, a multilevel laminectomy with instrumented fixation is required to prevent kyphotic deformity and myelopathy. Nevertheless, instrumentation of the cervical spine in children under the age of 8 years is challenging due to anatomical considerations and unavailability of specific instrumentation. Case Presentation: We present a case of 3D-printed model-assisted cervical spine instrumentation in a 4-year-old child with post-laminectomy kyphotic decompensation of the cervical spine and spinal cord injury 1 year after medulloblastoma metastasis resection in the upper cervical spine. Due to unavailability of specific instrumentation, 3D virtual planning was used to assess and plan posterior cervical fixation. Fixation with 3.5 mm lateral mass and isthmic screws was suggested and the feasibility of fixation was confirmed "in vitro" in a 3D-printed model preoperatively to reduce the possibility of intraoperative implant-spine mismatch. Intraoperative conditions completely resembled the preoperative plan and 3.5 mm polyaxial screws were successfully used as planned. Postoperatively the child made a complete neurological recovery and 2 years after the instrumented fusion is still disease free with no signs of spinal decompensation. Discussion/Conclusion: Our case shows that posterior cervical fixation with the conventional screw-rod technique in a 4-year-old child is feasible, but we suggest that suitability and positioning of the chosen implants are preoperatively assessed in a printed 3D model. In addition, a printed 3D model offers the possibility to better visualize and sense spinal anatomy "in vivo," thereby helping screw placement and reducing the chance for intraoperative complications, especially in the absence of intraoperative spinal navigation.

Purpose: The aim of this article is to present history, state of the art, and future trends in the treatment of acetabular fractures. Methods: Review of recent and historical literature. Results: Acetabular fractures are difficult to treat. The first descriptions of this injury already appeared in ancient Greek history, but intensive development started in the second half of the twentieth century after Judet and Letournel's seminal work. Their classification is still the gold standard today. It is actually a pre-operative planning system and is used to determine the most appropriate surgical approach. The therapy of choice for dislocated fractures is open reduction and internal fixation. Recent modern techniques based on high-tech computerized planning systems and 3D printing have been successfully integrated into orthopaedic trauma practice. Conclusion: There is no ideal surgical approach for acetabulum fracture treatment, so new approaches have been developed in recent decades. The best outcome series have shown good or excellent results, between 70 and 80%. [ABSTRACT FROM AUTHOR]

The effect of hyperbaric oxygen treatment (HBO) on sensory axon regeneration was examined in the rat. The sciatic nerve was crushed in both legs. In addition, the distal stump of the sural nerve on one side was made acellular and its blood perfusion was compromised by freezing and thawing. Two experimental groups received hyperbaric exposures (2.5 ATA) to either compressed air (pO[sub 2] = 0.5 ATA) or 100% oxygen (pO[sub 2] = 2.5 ATA) 90 minutes per day for 6 days. Sensory axon regeneration in the sural nerve was thereafter assessed by the nerve pinch test and immunohistochemical reaction to neurofilament. HBO treatment increased the distances reached by the fastest regenerating sensory axons by about 15% in the distal nerve segments with preserved and with compromised blood perfusion. There was no significant difference between the rats treated with different oxygen tensions. The total number of regenerated axons in the distal sural nerve segments after a simple crush injury was not affected, whereas in the nerve segments with compromised blood perfusion treated by the higher pO[sub 2], the axon number was about 30% lower than that in the control group. It is concluded that the beneficial effect of HBO on sensory axon regeneration is not dose-dependent between 0.5 and 2.5 ATA pO[sub 2]. Although the exposure to 2.5 ATA of pO[sub 2] moderately enhanced early regeneration of the fastest sensory axons, it decreased the number of regenerating axons in the injured nerves with compromised blood perfusion of the distal nerve stump.
