SummaryA six-year-old, spayed female Weimaraner dog was first presented with the complaint of hindlimb paresis and then hindlimb paralysis two years later after colliding with a tree. Radiographs and computed tomography revealed spinal fractures at lumbar vertebrae (L)2-3 and at L4-5. In addition, the spinal column was affected by new bone formation along the vertebral bodies, bridging the disc spaces, as seen in diffuse idiopathic skeletal hyperostosis (DISH). Open reduction and internal fixation was achieved with standard vertebral body plating. This is the first report of DISH-associated spinal fractures after minor trauma in a dog. Surgery resulted in return of the full function after the first, and in improvement of neurologic function after the second incident.

Abstract Objective The aim of this study was to describe minimally invasive spinal stabilization using a unilateral uniplanar external skeletal fixator (ESF, type 1a) with polymethylmethacrylate, and to review short- and long-term outcomes and complications in a clinical case series. Materials and Methods Medical records from animals affected by spinal fracture luxation were reviewed. The data included breed, age, gender, body weight, aetiology, preoperative and postoperative neurological state, radiographic findings, surgical treatment, pin size, number of pins and stabilized vertebrae, intra- and postoperative complications and neurological state at re-examinations. Results Thirty-two animals were identified; three were treated conservatively, 19 surgically and 10 were euthanatized. In eight dogs and six cats, the injured spinal column was treated with a laterally applied percutaneous type 1a ESF under fluoroscopic guidance. Positive profile end-threaded pins inserted were from 1.6/1.9 to 3.5/4.3 mm in dogs and 1.6/1.9 to 2/2.3 mm in cats and were placed into two to five vertebral bodies. At the re-examinations, the neurological status had improved in 12 animals, deteriorated in one, and was unchanged in another one. In eight cases, no complications were detected. The most common complications included erythema, exudation and pin loosening. Conclusion The present work shows that type 1a ESF can be successfully and minimally invasively applied to fractures and luxations of the spine in dogs and cats with minimal major complications.

Bony Enlargement

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterised by calcification and ossification of ligaments and entheses. The condition usually affects the axial skeleton, in particular, at the thoracic segment, though also other portions of the spine are often involved. DISH often involves also peripheral tendinous and/or entheseal sites either alone, or in association with the involvement of peripheral joints. At times, new bone formation involves the bone itself, but sometimes it involves joints not usually affected by osteoarthritis (OA) which result in bony enlargement of the epiphysis, joints space narrowing and a reduced range of motion. Because of the entheseal involvement, DISH can be mistaken for seronegative spondyloarthropathies or for a "simple" OA. Furthermore, other implications for the recognition of DISH include spinal fractures, difficult intubation and upper endoscopies, decreased response rates in DISH with concomitant spondyloarthritides, and increased likelihood to be affected by metabolic syndrome and cardiovascular diseases. This Atlas is intended to show the imaging finding in DISH in patients diagnosed with the condition by the Resnick classification criteria.

Chest compression has been a component of cardiopulmonary resuscitation (CPR) since 1960. Performance of high-quality CPR is critical for survival; however, chest compressions are traumatic and may result in injuries such as rib and sternal fractures. Spinal fractures have rarely been reported. We present a case of a 69-year-old male who suffered a cardiac arrest at home. He underwent 16 minutes of CPR with manual chest compressions, and no electrical shock and medications with return of spontaneous circulation (ROSC). Computed tomography scan showed unstable fracture of T9-T10. The patient was transferred to our Level I trauma center for continued post-arrest management and neurosurgical evaluation. An MRI confirmed the unstable spinal fracture which would have required surgical stabilization. The patient remained comatose, thus he was transitioned to comfort measures and expired. Spinal injuries following CPR are rare but should be considered in the post-arrest management stage. Computed tomography scan is the ideal screening modality.

Avascular necrosis of the vertebral body is extremely uncommon with majority of reported cases being secondary to traumatic compressive fractures. We describe the imaging findings of AVN of two contiguous lumbar vertebrae following osteoporotic compression fracture in an elderly patient with diffuse idiopathic skeletal hyperostosis which was confirmed on histopathological examination. The affection of two adjacent vertebrae and their intervening disc was an atypical feature and prompted us to consider neoplastic condition in the differential diagnosis.

SummaryObjective: To define the implantation corridors in feline thoraco-lumbar vertebrae (T10-L7) using computed tomography (CT) for optimal safe placement of the implants (screws/pins) in spinal column stabilization.Study design: Computed tomographic study.Materials and methods: Computed tomography images of feline spinal column (n = 10) were used to define the optimal safe implantation corridors (OSIC) in the transverse plane. The OSIC were defined as corridors allowing the greatest amount of bone purchase with safe margins for implantation of the bicortical implants. They were characterized by their insertion point, optimal angle (from the midsagital plane), maximum and minimum safe angles (from the same insertion points), length, and width.Results: The OSIC are located within the vertebral bodies. Insertion points were situated at the level of the vertebro-costal joint or the base of the transverse process of the vertebral body for thoracic and lumbar vertebrae, respectively. The mean optimal angle of the OSIC was 90.2° with a maximum deviation angle from optimal angle of 10° dorsally and 8.8° ventrally in thoracic vertebrae, and 90.5° with a maximum deviation angle from the optimal angle of 8.4° dorsally and 7.6° ventrally in lumbar vertebrae.Conclusion and clinical relevance: Corridors drilled in the vertebral body perpendicular to the midsagital plane (90°) or with a small angle (≤10°) of deviation from the optimal angle provide an optimal safe placement of bicortical implants. However, perpendicular implant placement may not always be feasible due to surrounding soft tissue structures.

Office Chair

Increasing numbers of people spend the majority of their working lives seated in an office chair. Musculoskeletal disorders, in particular low back pain, resulting from prolonged static sitting are ubiquitous, but regularly changing sitting position throughout the day is thought to reduce back problems. Nearly all currently available office chairs offer the possibility to alter the backrest reclination angles, but the influence of changing seating positions on the spinal column remains unknown. In an attempt to better understand the potential to adjust or correct spine posture using adjustable seating, five healthy subjects were analysed in an upright and reclined sitting position conducted in an open, upright MRI scanner. The shape of the spine, as described using the vertebral bodies’ coordinates, wedge angles, and curvature angles, showed high inter-subject variability between the two seating positions. The mean lumbar, thoracic, and cervical curvature angles were29±15°,-29±4°, and13±8° for the upright and33±12°,-31±7°, and7±7° for the reclined sitting positions. Thus, a wide range of seating adaptation is possible through modification of chair posture, and dynamic seating options may therefore provide a key feature in reducing or even preventing back pain caused by prolonged static sitting.

Abstract Background: Percutaneous vertebroplasty is the most common treatment for osteoporotic vertebral compression fracture. However, the morbidity of vertebroplasty-related complications, such as cement leakage, remains high. We tested a new technique of unilateral pulsed jet lavage and investigated its effect on the intravertebral pressure and bone cement distribution. Methods: Thirty lumbar vertebrae (L1-L5) from six cadaver spines were randomly allocated into two groups (with and without irrigation). Prior to vertebroplasty, pulsed jet lavage was performed through one side of the pedicle by using a novel cannula with two concentric conduits to remove the fat and bone marrow of the vertebral bodies in the group with irrigation. The control group was not irrigated. Then, standardized vertebroplasty was performed in the vertebral bodies in both groups. Changes in the intravertebral pressure during injection were recorded. Computed tomography (CT) was performed to observe the cement distribution and extravasations, and the cement mass volume (CMV) was calculated. Results: During cement injection, the average maximum intravertebral pressure of the unirrigated group was higher than that of the irrigated group (4.92kPa versus 2.22kPa, P<0.05). CT scans showed a more homogeneous cement distribution with less CMV (3832 mm 3 vs. 4344 mm 3 , P<0.05) and less leakage rate (6.7% vs. 46.7%, P<0.05) in the irrigated group than in the control group. Conclusions: Unilateral pulsed jet lavage can reduce intravertebral pressure and lower the incidence of cement leakage during vertebroplasty. An enhanced bone cement distribution can also be achieved through this lavage system.

Within spinal column, the lumbar vertebrae are the most durable and usually left behind in severely burnt body. European studies have reported that these vertebrae are useful for age estimation. However, it is widely acknowledged that different ancestry necessitates different methods and includes a range of variables, therefore a study specific to Thai population is needed for accuracy in the identification of Thai individuals. To investigate the correlation between lumbar vertebrae, and age of the individual, L1-L5 drilled out from 75 Thai cadavers. After undergoing histological processing each slide was photographed. The images were processed using an image processing technique to calculate the percentage of trabecular bone area over total area (%TBA/TA). Using the Statistical Package for the Social Sciences (SPSS) program, %TBA/TA of L1-L5 was calculated. The %TBA/TA of L1-L5 showed a negative correlation to age in both male and female groups. The %TBA/TA of L2 in the male group decreased most significantly with increase in age (r=-0.775) whereas in the female group, L3 showed the strongest negative correlation with age (r=-0.75. In the conclusion, it was found that trabecular bone of L2 showed the most significant correlation to increase in age in males whereas L3 showed the strongest correlation in females.

Introduction. Epidural fibrosis is an urgent problem in modern spinal surgery and orthopedics. The formation of connective tissue in the epidural space after performing surgical interventions on the spinal column inevitably leads to adhesion of the latter to the dura mater and compression of neural structures, followed by the formation of clinical and neurological symptoms. The  search for literary sources in domestic and foreign scientific databases has demonstrated the presence of several works studying the effectiveness of barrier methods for preventing the development of epidural fibrosis. It should be noted that the results of these studies are ambiguous and largely contradictory.The purpose was to study the effectiveness of using a spatially cross-linked polymer in the postoperative lumbar epidural fibrosis prevention in an experiment.Materials and methods. The study included 26 male Wistar rats (average body weight 338.5±9.07 g), which were divided into two groups: Group I (control, n = 12): animals underwent laminectomy at the level of vertebral bodies LVII – SI  without application of spatially crosslinked polymer; Group II (experimental, n = 14): animals underwent laminectomy at the level of vertebral bodies LVII – SI  followed by application of a spatially cross-linked polymer to the dura mater. The morphological and instrumental parameters were studied.Results. Significant differences were noted in the severity of epidural fibrosis (χ2 = 14.846, p = 0.003), the number of newly formed vessels (F = 14.371, p<0.001), the number of fibroblasts (F = 11.158, p<0.001), as well as in the severity of vertebral stenosis channe l according to multislice computed tomography (χ2 = 17.207, p=0.002) between the control and experimental groups of animals.Conclusion. Application of a spatially cross-linked polymer to the dura mater is an effective way to prevent the development of postoperative epidural fibrosis.
