RESUMEN
Systemic assessment is a pillar in the neurological, oncological, mechanical, and systemic (NOMS) decision-making framework for the treatment of patients with spinal metastatic disease. Despite this importance, emerging evidence relating systemic considerations to clinical outcomes following surgery for spinal metastatic disease has not been comprehensively summarised. We aimed to conduct a scoping literature review of this broad topic. We searched MEDLINE, Embase, Scopus, Cochrane Central Register of Controlled Trials, Web of Science, and CINAHL databases from Jan 1, 2000, to July 31, 2021. 61 articles were included, accounting for a total of 22â335 patients. Preoperative systemic variables negatively associated with postoperative clinical outcomes included demographics (eg, older age [>60 years], Black race, male sex, low or elevated body-mass index, and smoking status), medical comorbidities (eg, cardiac, pulmonary, hepatic, renal, endocrine, vascular, and rheumatological), biochemical abnormalities (eg, hypoalbuminaemia, atypical blood cell counts, and elevated C-reactive protein concentration), low muscle mass, generalised motor weakness (American Spinal Cord Injury Association Impairment Scale grade and Frankel grade) and poor ambulation, reduced performance status, and systemic disease burden. This is the first comprehensive scoping review to broadly summarise emerging evidence relevant to the systemic assessment component of the widely used NOMS framework for spinal metastatic disease decision making. Medical, surgical, and radiation oncologists can consider these findings when prognosticating spinal metastatic disease-related surgical outcomes on the basis of patients' systemic condition. These factors might inform a shared decision-making approach with patients and their families.

BACKGROUND: Intra- and juxta-articular osteoid osteoma (OO) is rare and can result in irreversible joint damage. Recently, arthroscopic surgery is being used more and more to avoid complications associated with other treatment modalities. METHODS: On October 13, 2019, we conducted a systematic review of the literature available in PubMed and EMBASE regarding the arthroscopic management of OO involving the joints of the upper extremity. Predetermined inclusion criteria were used to include any relevant article published on and before that date for further analysis. Treatment success rate and tumor recurrence rate were considered the primary outcomes in our analysis. RESULTS: Out of 113 studies, 19 met our inclusion criteria. Of the 32 reported cases in these 19 articles, ten involved the shoulder joint, 19 involved the elbow joint and three involved the wrist joint. Overall treatment success rate was 93.8%. Tumor recurrence rate was 0.0%. No postoperative complications (0.0%) were reported among cases involving the shoulder joint. Two out of 24 (8.3%) patients with elbow OO failed arthroscopic treatment due to incomplete excision, and two (4%) experienced minor complications. Among the three cases of wrist OO, two (66.7%) patients had residual postoperative pain and decreased hand grip strength. CONCLUSION: Arthroscopic management of OO of the upper extremity joints is highly successful and results in no tumor recurrence; however, there is a risk of incomplete resection in areas more difficult to access by arthroscopy.

BACKGROUND: There are easily accessible tools on smartphones (APP) for measuring elbow range of motion (ROM). The purpose of this study is to evaluate the validity of a particular APP in determining elbow ROM in comparison with the commonly used goniometer (GON), surgeon estimation of range (EST) and measurement on X-ray (XR). METHODS: The study included 20 patients (40 elbows). Flexion, extension, pronation and supination were measured using three different methods: EST, GON and APP. Radiographic measurements were taken using the average humeral diaphysis axis and dorsal midthird of ulna in flexion and extension. RESULTS: The accuracy of the three different methods has been compared to GON using statistical analysis (ANOVA and paired samples test). There was no statistically significant difference for XR flexion measurement (mean of 2.8° ± 1.5°). The APP overestimated flexion (mean of 6.4° ± 1.0°), and EST underestimated it (mean of - 7.9° ± 1.1°). For extension, the mean difference was 2.8° ± 0.7° for EST and - 26.8° ± 3.1° for XR. The APP method did not significantly differ from GON. Supination accuracy was greater with EST (2.7° ± 1.7°) than with APP (5.9° ± 1.9°). There was no difference for pronation measurement with both EST and APP. CONCLUSIONS: This study is the first comparing four measurement techniques of elbow ROM. Our results showed that EST was only accurate for forearm rotation. The XR scored the best for flexion but is less reliable for extension. Surprisingly, compared to GON, APP did not correlate as we expected for flexion and supination, but the other methods were also inaccurate. We found APP to be very useful to measure complete arc of motion (difference between maximal flexion and maximal extension).

BACKGROUND: Osteogenesis imperfecta (OI) is a heritable skeletal disorder characterized by bone fragility and short stature that is usually due to mutations in 1 of the 2 genes that code for collagen type I α-chains. The association between hip dysplasia and OI has not been systematically investigated. In this single-center study, we retrospectively reviewed all cases of OI associated with hip dysplasia to describe clinical characteristics and the effect of therapy. METHODS: We reviewed the charts of 687 patients with OI who were seen at the Shriners Hospital for Children in Montreal between 1999 and 2013 to identify patients with a diagnosis of hip dysplasia. Clinical characteristics and the course after therapeutic interventions were extracted from the charts. RESULTS: Hip dysplasia was diagnosed in 8 hips of 5 patients (4 boys, 1 girl; age at diagnosis ranged between 3 wk and 27 mo old). The prevalence of hip dysplasia and OI was therefore 0.87% (per patient). In 4 of the 5 patients (80%), OI was caused by mutations affecting the C-propeptide of collagen type I, which is otherwise rare in OI. Among the 26 patients with C-propeptide mutations followed at our institution, 4 (15%) had hip dysplasia. Pavlik harness treatment was attempted in 2 patients (3 hips) but was not effective in either case and resulted in avascular necrosis of 1 hip. Femoral varus derotational shortening osteotomies using a telescopic rod were performed in all 8 hips along with a closed reduction in 4 hips and an open reduction in 4 hips. Concomitant pelvic osteotomies were performed in 2 hips (1 patient). Surgery resulted in redislocation of 1 hip; all other surgically treated hips remained reduced. CONCLUSIONS: Clinical screening for hip dysplasia is difficult in OI owing to the bowing of the proximal femur and the risk of causing fractures. OI patients with positive C-propeptide mutation should therefore be screened for hip dysplasia by use of ultrasound. Presence of a C-propeptide mutation appears to be a risk factor for hip dysplasia (80%). It appears that Pavlik harness treatment is not useful in children with OI. The usual treatment of children with OI who pull to stand or started walking with femoral deformity is femoral osteotomy and rodding. In case of associated hip dysplasia with a dislocation, open reduction of the hip and a possible concomitant pelvic osteotomy appears to be a valid management option. LEVEL OF EVIDENCE: Level IV.

Introduction Musculoskeletal (MSK) disorders are one of the common health issues affecting people of various ages. The main risk factors for musculoskeletal pain are age, obesity, gender, level of education, psychosocial factors, occupational factors, decreased mobility and flexibility, and common factors such as consuming TV and video games. College students, especially medical students, are at a higher risk of these complaints as they have longer hours of studying than most faculties due to the competitiveness of their specialty. The objective of this study was to identify the relationship between musculoskeletal pain and studying hours in medical students in Jeddah, Saudi Arabia, and to increase awareness of this problem. Methods This cross-sectional study was conducted in 2022. Data was collected using an online questionnaire. A total of 314 participants were included in this study. The demographic variables, studying hours, studying locations, and postures were collected and analyzed. Results A total of 314 medical students were included in this study. The majority were males (71.0%) and, the mean age was 22.05±2.13 years. Most of them were sixth-year students, and most of them reported studying between three and four hours (40.1%), with the most common studying location reported being the students' home or residence (79.3%). The number of daily studying hours had no significant effect on the occurrence of musculoskeletal problems. Conclusion There was no significant relationship between the number of studying hours and the MSK pain. Clinical trials could be used to evaluate the most effective approaches to alleviate MSK pain in medical students.
RESUMEN
Cladiella-derived natural products have shown promising anticancer properties against many human cancer cell lines. In the present investigation, we found that an ethyl acetate extract of Cladiella pachyclados (CE) collected from the Red Sea could inhibit the human breast cancer (BC) cells (MCF and MDA-MB-231) in vitro (IC50 24.32 ± 1.1 and 9.55 ± 0.19 µg/mL, respectively). The subsequent incorporation of the Cladiella extract into the green synthesis of silver nanoparticles (AgNPs) resulted in significantly more activity against both cancer cell lines (IC50 5.62 ± 0.89 and 1.72 ± 0.36, respectively); the efficacy was comparable to that of doxorubicin with much-enhanced selectivity. To explore the mode of action of this extract, various in silico and network-pharmacology-based analyses were performed in the light of the LC-HRESIMS-identified compounds in the CE extract. Firstly, using two independent machine-learning-based prediction software platforms, most of the identified compounds in CE were predicted to inhibit both MCF7 and MDA-MB-231. Moreover, they were predicted to have low toxicity towards normal cell lines. Secondly, approximately 242 BC-related molecular targets were collected from various databases and used to construct a protein-protein interaction (PPI) network, which revealed the most important molecular targets and signaling pathways in the pathogenesis of BC. All the identified compounds in the extract were then subjected to inverse docking against all proteins hosted in the Protein Data bank (PDB) to discover the BC-related proteins that these compounds can target. Approximately, 10.74% of the collected BC-related proteins were potential targets for 70% of the compounds identified in CE. Further validation of the docking results using molecular dynamic simulations (MDS) and binding free energy calculations revealed that only 2.47% of the collected BC-related proteins could be targeted by 30% of the CE-derived compounds. According to docking and MDS experiments, protein-pathway and compound-protein interaction networks were constructed to determine the signaling pathways that the CE compounds could influence. This paper highlights the potential of marine natural products as effective anticancer agents and reports the discovery of novel anti-breast cancer AgNPs.
RESUMEN
Coronavirus disease (COVID-19) has forced the urgent lockdown of schools and colleges worldwide. To ensure the continuity of education a shift from traditional teaching to e-learning was required. This study aims to identify factors that affect students' satisfaction and continued intention towards e-learning. A questionnaire was distributed to medical and dental students (second to sixth year) from different universities in Saudi Arabia. The study synthesizes the expectation-confirmation theory (ECT) and the theory of planned behavior (TPB) to predict students' satisfaction and intention to continue using e-learning using a validated self-administered questionnaire. We used the structural equation model to analyze the results and assess the study's hypotheses. A total of 870 completed questionnaires were received (67% response rate). The results showed that students were at a moderate level of satisfaction (median = 3.5). According to the ECT, both perceived usefulness and confirmation significantly influenced students' satisfaction (ß = -.69 and ß = .82, respectively). Satisfaction was the strongest predictor of students' continued intention (ß = 1.95). Among the TPB constructs, perceived behavioral control (ß = .51), attitudes (ß = .39), and subjective norms (ß = .36) had a significant positive influence on their intention to use e-learning. The results suggest efforts to increase students' satisfaction and intention with e-learning should be directed to adopting easy and useful e-learning platforms. In addition, training and motivating students to continue e-learning and increasing their confidence to ensure the effective and efficient use of such teaching modalities.

OBJECTIVE: Musculoskeletal disorders (MSDs) are injuries to the musculoskeletal (MSK) system that occur due to repetitive or singular trauma and negatively affect one's daily life. Dentistry is a field that exposes professionals to the highest rate of work-related MSDs. This study aimed to assess the prevalence and predictors of MSK pain among a sample of dental students. METHODS: A cross-sectional study was conducted among a sample of 377 dental students and interns at the dental school of King Abdulaziz University, Jeddah, Saudi Arabia. We distributed a validated questionnaire, the Nordic Back Pain Questionnaire, which included additional questions, to all dental students participating in clinical practice and to dental interns. Categorical variables were described by presenting frequencies and percentages, and continuous variables by displaying means and standard deviations. Logistic regression was performed to identify predictors for developing MSK pain over the last 12 months. RESULTS: Overall, 91.2% of the participants experienced MSK pain or discomfort in one or more body parts over the last 12 months. The highest prevalence was for neck pain (69.2%), followed by shoulder pain (67.1%) and lower back pain (65%). Females were more likely than males to experience MSK pain (odds ratio [OR] = 2.98, 95% confidence interval [CI]: 1.3-6.7), and those who exercised regularly were less likely to experience MSK pain than were those who did not (OR = 0.27, 95% CI: 0.1-0.6). CONCLUSION: This study showed a concerningly high prevalence of MSD symptoms among dental students, especially in the neck, shoulders, and lower back. Educational and occupational health programs in preclinical years could be effective for reducing MSK pain.
RESUMEN
STUDY DESIGN: Cross-sectional survey study. OBJECTIVE: To evaluate the prevalence of burnout, assess the personal and professional characteristics associated with burnout in spine surgeons and determine their quality of life. SUMMARY OF BACKGROUND DATA: Burnout is a syndrome characterized by emotional exhaustion, depersonalization, and decreased sense of accomplishment that leads to decreased effectiveness at work. To date, there has been a lack of information on the prevalence of burnout among spine surgeons worldwide and the risk factors associated with this condition. METHODS: An electronic survey with members of AO Spine was performed in May 2018. The survey evaluated demographic variables, practice characteristics, burnout, and quality of life. Maslach Burnout Inventory (MBI) and EuroQol 5-dimensions (EQ5D) were used to evaluate burnout and quality of life, respectively. RESULTS: A total of 818 surgeons from 86 countries completed the survey. The prevalence of burnout was 30.6%. In the multiple linear model, emotional fatigue was independently associated with younger age (Bâ=â-0.17, CI95%â=â-0.26 to -0.07, Pâ<â0.0001), and longer working hours per week (Bâ=â-2.71, CI95%â=â-4.34 to -1.07, Pâ=â0.001); depersonalization was independently associated with younger age (Bâ=â-0.13, CI95%â=â-0.19 to -0.07, Pâ<â0.0001), practicing outside Latin America (LA) (Bâ=â0.71, CI95%â=â0.41-1.01, Pâ<â0.0001) and currently being a fellow (Bâ=â0.54, CI95%â=â0.06-1.02, Pâ=â0.02); and higher scores of personal fulfilment was associated with practicing in LA (Bâ=â-1.27, CI95%â=â-1.69 to -0.85, Pâ<â0.0001). CONCLUSION: Burnout is a common condition among spine surgeons worldwide. There is a significant association between burnout scores and decreased general quality of life. These results highlight the need to develop interventional programs to better identify, prevent, and manage this condition among practicing spine surgeons.Level of Evidence: 4.

Intramedullary nailing is the mainstay of treatment for unstable intertrochanteric hip fractures. Various complications have been described with the use of these nails. We report an unusual complication whereby the lag screw completely missed the nail. We hypothesize that this previously unreported complication may be related to a specific flexible carbon fiber aiming device. Surgeon awareness and thorough intraoperative imaging are crucial to avoiding this complication.
RESUMEN
Stand-alone cervical laminectomy for degenerative cervical myelopathy (DCM) has become increasingly rare due to risk of postlaminectomy kyphosis. This article discusses the biomechanics of cervical degeneration and how laminectomy effects spine stability, and summarizes relevant clinical studies to help guide surgical decision-making for the posterior treatment of DCM. Laminectomy and fusion remains a safe and efficacious treatment. Stand-alone laminectomy should only be used for a highly selected patient population with relative stiff lordotic cervical spines, using care to not disrupt facets and C2 and C7 muscle attachments.

OBJECTIVE The aim of this study was to evaluate the anatomical and surgical risk factors for screw-related facet joint violation at the superior level in lumbar fusion. METHODS The authors conducted a retrospective review of a consecutive series of posterior lumbar instrumented fusions performed by a single surgeon. Inclusion criteria were primary lumbar fusion of 1 or 2 levels for degenerative disorders. The following variables were analyzed as possible risk factors: surgical technique (percutaneous vs open screw placement), depth of surgical field, degree of anterior slippage of the superior level, pedicle and facet angle, and facet degeneration of the superior level. Postoperative CT scans were evaluated by 2 independent reviewers. Axial, sagittal, and coronal views were reviewed. Pedicle screws were graded as intra-articular if they clearly interposed between the superior and inferior facet joints of the superior level. Multivariate logistic regression analyses were conducted to assess the factors associated with this complication. RESULTS One hundred thirty-one patients were included. Interobserver reliability for facet joint violation assessment was high (κ = 0.789). The incidence of superior facet joint violation was 12.59% per top-level screw (33 of 262 proximal screws). The rate of facet violation was 28.0% in the percutaneous technique group (14 of 50 patients) and 12.3% in the open surgery group (10 of 81 patients) (OR 2.26, 95% CI 1.09-4.21; p = 0.024). In multivariate logistic regression analysis, independent predictors of facet violation were percutaneous screw placement (adjusted OR 3.31, 95% CI 1.42-7.73; p = 0.006), right-side pedicle screw (adjusted OR 3.14, 95% CI 1.29-7.63; p = 0.011), and facet angle > 45° (adjusted OR 10.95, 95% CI 4.64-25.84; p < 0.0001). CONCLUSIONS The incidence of facet joint violation was higher in percutaneous minimally invasive than in open technique for posterior lumbar spine surgery. Also, coronal orientation of the facet joint is a significant risk factor independent of the surgical technique.

STUDY DESIGN: Systematic review. OBJECTIVES: To determine the preoperative computed tomography (CT) myelogram imaging parameters in patients diagnosed with degenerative cervical myelopathy (DCM) that correlate with severity of DCM and predict postoperative patients' functional outcome. METHODS: An electronic database search was performed using Ovid Medline and Embase. CT myelogram studies investigating the correlation between imaging characteristics and DCM severity or postoperative outcomes were included. Two independent reviewers performed citation screening, selection, qualitative assessment, and data extraction using an objective and blinded protocol. RESULTS: A total of 5 studies (402 patients) were included in this review and investigated the role of preoperative CT myelogram parameters in predicting the functional outcome after surgical treatment of DCM. All studies were retrospective cohort studies. CT myelogram characteristics included the transverse area of the spinal cord at maximum level of compression, spinal canal narrowing, number of blocks, spinal canal diameter, and flattening ratio. There is low evidence suggesting that patients with a preoperative transverse area of the spinal cord >30 mm2 at the level of maximum compression have better postoperative recovery and outcome. We found no studies investigating the correlation between preoperative CT myelogram parameters and DCM severity. CONCLUSIONS: Patients with greater transverse area of spinal cord at the level of maximum compression on the preoperative CT myelogram are more likely to have better neurological outcome after surgery. There is insufficient evidence to suggest that any of the other CT myelogram parameters investigated are predictors of postoperative outcomes in patients with DCM.
RESUMEN
Ischiospinal Dysostosis (ISD) is a complex and very rare medical entity. It is associated with kyphoscoliosis, dysplasia or aplasia of the ischial rami, segmental anomalies of the bony vertebrae, and peculiar facial morphologies. In this case report, we present a child with Ischiospinal Dysostosis and Pierre-Robin Syndrome. This case report is unique as we followed the patient for 13 years in which he had multiple spinal procedures to treat his kyphoscoliosis. In this paper, we elucidated the number of case reports with documented follow-up regarding spinal cord injury or other complications of ISD and its management.
RESUMEN
STUDY DESIGN: A retrospective cohort study. OBJECTIVE: The aim of this study is to assess the association of demographic and perioperative factors with clinical outcomes of lumbar interbody fusion with a porous nitinol (TiNi) implant for degenerative disc disease. METHODS: Forty-one patients with degenerative lumbar disease were prospectively followed for a mean of 4.8 years. All patients were instrumented with porous TiNi interbody fusion devices. The Oswestry Disability Index (ODI) and return to work were used to assess clinical outcomes. Factors including age, body mass index, smoking status, insurance status, number of comorbidities, duration of surgery, estimated blood loss, number of levels fused, time since surgery, and preoperative ODI score were assessed. A multiple linear regression analysis was performed to look for demographic and perioperative factors associated with clinical outcome. RESULTS: All patients except one (98%) showed complete fusion on radiography at 1 year. Estimated blood loss and duration of surgery were significantly associated with higher postoperative ODI scores (P = .002 and P = .019, respectively). Smoking status, salary insurance status, age, body mass index, number of comorbidities, number of levels fused, time since surgery, and preoperative ODI score were not significantly associated with outcome. CONCLUSIONS: Porous nitinol permitted fusion rates similar to those reported in the literature for alternative fusion cages. Poor functional outcome of patients was strongly associated with intraoperative blood loss and duration of surgery. We believe that estimated blood loss should be carefully evaluated in studies of postoperative outcome, as it may affect midterm outcomes. LEVEL OF EVIDENCE: Level 3.
RESUMEN
STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Several studies have shown that the accuracy of pedicle screw placement significantly improves with use of computer-assisted surgery (CAS). Yet few studies have compared the incidence of postoperative complications between CAS and conventional techniques. The objective of this study is to determine the difference in postoperative complication rates between CAS and conventional techniques in spine surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent posterior lumbar fusion from 2011 to 2013. Multivariate analysis was conducted to demonstrate the difference in postoperative complication rates between CAS and conventional techniques in spine surgery. RESULTS: Out of 15 222 patients, 14 382 (95.1%) were operated with conventional techniques and 740 (4.90%) were operated with CAS. Multivariate analysis showed that patients in the CAS group had fewer odds to experience adverse events postoperatively (odds ratio [OR] = 0.57, P < .001). Minor adverse events occurred in 2905 (20.2%) patients in the conventional group and in 98 (13.2%) patients in the CAS group (OR = 0.57, P < .001). Blood transfusion was present in 2488 (17.3%) of the patients in the conventional group compared to 81 (11.0%) of the patients in the CAS group (OR = 0.56, P < .001). The mean operative time in the conventional group was 205.2 ± 106.1 minutes, and it was 227.0 ± 111.9 minutes in the CAS group. This difference was statistically significant (r = 20.14, P < .001). CONCLUSION: This article examined the complications in lumbar spinal surgery with or without the use of CAS. These results suggest that CAS may provide a safer technique for implant placement in lumbar fusion surgeries.
RESUMEN
Introduction. Simultaneous bilateral quadriceps tendon ruptures (SBQTR) are uncommon knee injuries and most frequently occur in male patients, over 50 years of age. It can be associated with one or more predisposing risk factors like obesity, steroids use, and hyperparathyroidism. The main focus of this paper is to review SBQTR in obese patients. Case Report. We are reporting the youngest patient in the literature to date, a 24-year-old obese male patient, who presented to the emergency department complaining of bilateral knee pain and inability to walk after a fall during a basketball game. His clinical examination revealed the presence of a palpable suprapatellar gap and loss of knee extension bilaterally. Magnetic resonance imaging (MRI) confirmed that both of his quadriceps tendons were ruptured. A day after his diagnosis, the patient underwent successful operative repair followed by rehabilitation. At the two-year follow-up, the patient had full strength of both quadriceps muscles with no extension lag. Conclusion. The diagnosis of SBQTR can be challenging. Early diagnosis and treatment are associated with better functional outcome compared to delayed treatment. Physicians should have a high index of clinical suspicion in order not to miss such an injury and achieve favourable outcomes.
RESUMEN
BACKGROUND CONTEXT: Early-onset scoliosis often occurs by the age of 5 years and is attributed to many structural abnormalities. Syndromic early-onset scoliosis is considered one of the most aggressive types of early-onset scoliosis. Treatment starts with serial casting and bracing, but eventually most of these patients undergo growth-sparing procedures, such as a single growing rod, dual growing rods, or a vertical expandable titanium prosthetic rib. PURPOSE: This case report aimed to describe an unusual complication of erosion of a growing rod through the lamina that caused spinal cord compression in an 8-year-old girl with early-onset scoliosis. STUDY DESIGN: This is a case report. METHODS: A retrospective chart review was used to describe the clinical course and radiographic findings of this case after rod erosion into the spinal canal. RESULTS: The patient underwent successful revision surgery removing the rod without neurologic complications. CONCLUSIONS: Patients with syndromic early-onset scoliosis are more prone to progressive curves and severe rotational deformity. We believe that the severe kyphotic deformity in addition to the dysplastic nature of the deformity in this population may predispose them to this unusual complication.

Bucket-handle meniscal tears used to be rare in children younger than 10 years of age. However, nowadays, we encounter more cases because of increased sport and recreational activities. In this paper, we report on a 9-year-old girl who presented with an isolated medial meniscal bucket-handle tear of the right knee and review the literature for similar cases. Bucket-handle meniscal tears are rare in young children. However, it should be ruled out in patients with knee pain and mechanical symptoms following knee injury.

Congenital absence of cervical spine pedicle can be easily misdiagnosed as facet dislocation on plain radiographs especially in the acute trauma setting. Additional imaging, including computed tomography (CT)-scan with careful interpretation is required in order to not misdiagnose cervical posterior arch malformation with subsequent inappropriate management. A 39-year-old patient presented to the emergency unit of our university hospital after being trampled by a cow over her back and head followed by loss of consciousness, retrograde amnesia and neck pain. Her initial cervical CT-scan showed possible C5-C6 dislocation, then, it became clear that her problem was a misdiagnosed congenital cervical abnormality. Patient was treated symptomatically without consequences. The congenital absence of a cervical pedicle is a very unusual condition that is easily misdiagnosed. Diagnosis can be accurately confirmed with a CT-scan of the cervical spine. Symptomatic conservative treatment will result in resolution of the symptoms.
