Osteophytes grow on vertebral bodies and sometimes form a sharp edge, which can induce traumatic abdominal aortic injury (TAAI). However, these cases are extremely rare, although osteophytes grow in almost everyone with age. Herein, we report a rare case of TAAI due to a sharp osteophyte dislocation following a compression fracture, with a literature review. An 83-year-old man presented with back pain after a fall and subsequently developed shock. His lactate level was elevated on arrival, although we could not identify the cause of the shock. Enhanced computed tomography (CT) revealed a compression fracture of the lumbar spine, a sharp osteophyte penetrating the abdominal aorta, and contrast media spurting to the retroperitoneum. We immediately transfused, administered continuous noradrenaline to maintain his vital signs, and consulted a vascular surgeon and radiologist to arrange for an emergency operation. However, the operating room was not immediately available. We tried to evacuate a trauma center, which took time due to the COVID-19 outbreak. Thereafter, the patient\'s condition deteriorated, resulting in a pulseless electrical activity, and he passed away 3 h after arrival. Afterward, the previous CT image and a sharp osteophyte were observed in the lumbar vertebrae in contact with the abdominal aorta. There were only eight reports where the aorta was injured by osteophytes. From our review, unlike the proportion of common TAAI, injuries due to strong external forces were relatively small. There was no specific symptom, and the vertebral levels of osteophytes were concentrated in Th12-L3. The most common morphology of aorta injuries is pseudoaneurysm formation. Moreover, five of the patients developed hemorrhage. Considering these previous reports, we should pay attention to the aorta in front of the vertebral bodies regardless of the mechanism of injury when a CT image of patients shows osteophytes.

Vocal fold paralysis occurs when the function of the vagus nerve or its distal branch, the recurrent laryngeal nerve, is diminished or absent. Bilateral vocal fold paralysis can present with varying degrees of severity and is sometimes fatal. Cervical osteophytes are a rare cause of bilateral vocal fold paralysis, with only a few cases reported. A 68-year-old man was brought to the emergency department because of a disturbance in consciousness following a fall. A CT scan of the head showed multiple cranium and brain injuries, and the patient was treated conservatively by neurosurgery. The day after the injury, dysphagia and dysarthria appeared. On the third day of admission, both vocal cords were fixed bilaterally in the paramedian position, and the patient was nearly choking on sputum. A CT scan showed that the intracranial lesions gradually improved, but the vocal cord paralysis remained. A cervical CT scan was performed to investigate the cause of the vocal cord paralysis, which revealed that cervical vertebral osteophytes were compressing the tracheoesophageal groove and the glottis. The patient was transferred to the hospital for rehabilitation, although bilateral vocal cord paralysis remained. Although rare, clinicians need to be aware that cervical osteophytes can cause vocal fold paralysis, which may be manifested when combined with further trauma. It is also important to note that traumatic vocal cord paralysis can be delayed.

Dysphagia is a common symptom with various underlying etiologies, making its management challenging even for experienced physicians. The presence of osteophytes in the cervical spine may often impede swallowing, displace the larynx, and cause a sore throat. We describe a case of an 85-year-old male who presented with a two-year history of progressive dysphagia, exacerbated over the last two months, especially with solid foods and liquids, prompting an ENT evaluation. Despite prior investigations, including normal gastroscopy and empirical pain management, further assessment revealed bulging masses in the hypopharynx indicative of cervical osteophytes. Conservative management, including speech and swallow therapy, dietary modifications, and pharmacological interventions, resulted in significant symptom improvement without surgical intervention. This case demonstrates the effectiveness of conservative treatment measures in treating dysphagia caused by cervical osteophytes, emphasizing the significance of a multidisciplinary approach for optimal patient care.

An acutely locked knee is an incapacitating condition that requires urgent orthopedic intervention. Common causes of the locked knee include a tear of the meniscus, stump of a ruptured anterior cruciate ligament (ACL), loose body, and osteochondral injury. This report describes a rare case of an acutely locked knee due to the concurrent presence of a loose body and a degenerative osteophyte, highlighting the diagnostic challenges and treatment strategies employed for successful management. Notably, to our knowledge, there is no preceding report documenting the same etiology.

Dysphagia due to extensive ossification at anterior segments of the cervical spine is a rare occurrence and is usually attributable to diffuse idiopathic skeletal hyperostosis (DISH). We present the case of a 74-year-old female with dysphagia most likely due to ossification in pseudohypoparathyroidism type 1a (PHP1a). PHP1a is a rare, autosomal dominant disorder caused by mutations in the GNAS1 gene. Our patient had characteristic phenotype features of PHP1a, also known as Albright\'s hereditary osteodystrophy (AHO), which was diagnosed without genetic confirmation. She was conservatively treated with dietary measures and observation, and reported persisting symptoms of dysphagia at six-month follow-up. This is the first case to describe dysphagia in PHP1a with a similar presentation to DISH.

OBJECTIVE: The objective of this cross-sectional case-control study was to determine the prevalence and size of marginal and subarticular osteophytes in patients with osteoarthritis (OA), and to compare these to that of a control group.
METHODS: We investigated femoral heads from 25 patients with OA following hip replacement surgery, and 25 femoral heads from a control group obtained post-mortem. The area and boundary length of the femoral head, marginal osteophytes, and subarticular osteophytes were determined with histomorphometry. Marginal osteophytes were defined histologically as bony projections at the peripheral margin of the femoral head, while subarticular osteophytes were defined as areas of bone that expanded from the normal curvature of the femoral head into the articular cartilage.
RESULTS: The prevalence of OA patients with marginal- and subarticular osteophytes were 100 and 84%, respectively. Whereas the prevalence of the participants in the control group with marginal- and subarticular osteophytes were 56 and 28%, respectively. The area and boundary length of marginal osteophytes was (median (Interquartile range)) 165.3mm2 (121.4-254.0) mm2 and 75.1 mm (50.8-99.3) mm for patients with OA compared to 0 mm2 (0-0.5) mm2 and 0 mm (0-0.5) mm for the control group (P <  0.001). For the subarticular osteophytes, the area and boundary length was 1.0 mm2 (0-4.4) mm2 and 1.4 mm (0-6.5) mm for patients with OA compared to 0 mm2 (0-0.5) mm2 and 0 mm (0-0.5) mm for the control group (P <  0.001).
CONCLUSIONS: As expected, both marginal- and subarticular osteophytes at the femoral head, were more frequent and larger in patients with OA than in the control group. However, in the control group, subarticular osteophytes were more prevalent than expected from the minor osteophytic changes at the femoral head margin, which may suggest that subarticular osteophytes are an early degenerative phenomenon that ultimately might develop into clinical osteoarthritis.

UNASSIGNED: Osteochondral lesions (OCLs) and bony impingement are common secondary lesions of chronic lateral ankle instability (CLAI), but the risk factors that predict OCLs and bony impingement are unknown.
UNASSIGNED: To analyze the risk factors for the development of OCLs and osteophytes in patients with CLAI.
UNASSIGNED: Case-control study; Level of evidence, 3.
UNASSIGNED: Patients diagnosed with CLAI at our institution from June 2007 to May 2018 were enrolled. The assessed potential risk factors were age, sex, postinjury duration, body mass index, injury side, and ligament injury type (isolated anterior talofibular ligament [ATFL] injury, isolated calcaneofibular ligament [CFL] injury, or concomitant ATFL and CFL injuries). Univariate and multivariate logistic regression analyses were performed to evaluate the association between these factors and the presence of OCLs and osteophytes.
UNASSIGNED: A total of 1169 patients with CLAI were included; 436 patients (37%) had OCLs and 334 (31%) had osteophytes. The presence of OCLs was significantly associated with the presence of osteophytes (P < .001). Male sex and older age were significantly associated with the presence of OCLs in the medial and lateral talus. A postinjury duration of 5 years or longer was significantly associated with the presence of OCLs in the medial talus (odds ratio [OR], 1.532; 95% CI, 1.023-2.293; P = .038) but not in the lateral talus. ATFL and CFL injuries were both significantly associated with the presence of lateral OCLs. Risk factors for the presence of osteophytes were male sex, older age, postinjury duration 5 years or longer, and CFL injury. Patients with concomitant ATFL and CFL injuries were significantly more likely to have osteophytes than were patients with single-ligament injuries (P = .018).
UNASSIGNED: Risk factors for OCLs and osteophytes were postinjury duration of 5 years or longer, older age, and male sex. ATFL injury was associated with the presence of lateral OCLs, whereas CFL injury was associated with the presence of lateral OCLs and osteophytes. Patients with these risk factors should be closely monitored and treated to reduce the incidence of ankle arthritis.

BACKGROUND: Surgical strategy of multisegmental spinal fixation that includes atlantoaxial joint for patients having cervical spondylosis-related symptoms of severe myelopathy is analyzed.
OBJECTIVE: Surgical outcome of patients presenting with \"severe\" symptoms of cervical myelopathy having multisegmental degenerative cervical spondylosis and treated by multisegmental spinal fixation is analyzed. Atlantoaxial joint was included in the fixation construct in majority of patients. No bone, soft tissue, osteophyte, or disc resection for decompression was done.
METHODS: Sixty-four patients having multisegmental cervical spondylosis who presented with symptoms of severe myelopathy were surgically treated during the period from March 2013 to December 2018. On the basis of the concept that instability is the primary cause of spinal degeneration, multisegmental spinal fixation was done in all patients. Atlantoaxial joint was included in the fixation construct in 48 patients. The levels of spinal fixation were determined on the basis of direct observation of facet joints and by manual manipulation and were guided by the presenting clinical features and radiological information. Clinical monitoring was done using Goel clinical grading, modified Japanese Orthopedic Association Score, and visual analog score parameters. Patient satisfaction index assessed the functional and symptomatic improvement.
RESULTS: During the follow-up that ranged from 6 to 75 months, all patients improved in their clinical status. Fifty-five (85.9%) patients could walk independently or with mild support.
CONCLUSIONS: Multisegmental spinal fixation that includes atlantoaxial joint in most patients forms a rational treatment strategy for patients of cervical spondylosis presenting with severe symptoms of myelopathy.

The aim of this study is to define the relationship between anatomical and pathological cervical structures and the impaction of ingested foreign bodies (FBs). The effects of such structures on deglutition have been previously discussed, however their contribution to FB impaction has not yet been examined. This was a retrospective case-control study of 171 patients who underwent computed tomography (CT) scans over the period 2008-2014: 57 patients with an esophageal or hypopharyngeal FB; the other 114 comprised the control group, selected using the \'neighbor control\' method. CT scans were reviewed for measurements of cervical structures. The mean age was 63 ± 13 years and 55 ± 17 years in the case and control groups, respectively (p-value = 0.003). Age was the only demographic or clinical characteristic which demonstrated a significant difference. Overall, 24 patients had cervical osteophytes: 28 %(16) with an impacted FB, compared with 7 %(8) from the control group (p-value < 0.001). Of the patients with osteophytes and impacted FBs, 62.5 % had the FB lodged at a vertebral level corresponding to their osteophytes, while another 18.75 % had the FB within three vertebral levels above the osteophytes. Stepwise logistic regression revealed that osteophytes were a significant factor, independent of older age (p-value = 0.004). Adjusted odds ratio for FB impaction in the presence of osteophytes was 4.04. Ventral cervical osteophytes increase the risk for FB impaction in the upper digestive tract. This risk is independent of older age. These findings can be of value in preventive medicine, and emphasize the importance of looking for spinal changes in patients with recurrent FB impaction.
