Disfagia por osteofitose cervical anterior: relato de caso / Dysphagia due to anterior cervical osteophytosis: case report

RESUMO Osteofitose cervical anterior é uma condição não inflamatória caracterizada por calcificação ou ossificação dos ligamentos paravertebrais anterolaterais da coluna cervical. Acomete 20 a 30% dos idosos, sendo responsável por 1,6% das etiologias identificáveis da disfagia na população senil. Em estados avançados, a disfagia por osteofitose cervical pode levar a complicações como desnutrição, perda de peso e pneumonia aspirativa. Este estudo visa alertar para a suspeição desse diagnóstico à equipe multidisciplinar que cuida do idoso disfágico, possibilitando tratamento oportuno e precoce da condição. É relatado o caso de um paciente masculino de 66 anos com disfagia tipo engasgo para sólidos e refluxo nasal de alimentos há 1 ano. Videoendoscopia da deglutição evidenciou abaulamento da parede posterior da faringe e, à oferta de alimento sólido, restrição à retroflexão da epiglote, refluxo nasal do alimento e grande quantidade de resíduo alimentar sobre a lesão. Tomografia computadorizada de coluna cervical identificou a presença de osteófitos cervicais anteriores entre as vértebras C3 e C6, o maior com comprimento anteroposterior de 12 milímetros, estreitando a coluna aérea ao nível da oro- e hipofaringe. O paciente foi adequadamente tratado com fonoterapia da deglutição. A estratégia inicial de tratamento para a osteofitose sintomática deve ser conservadora, geralmente com boa resposta à fonoterapia da deglutição. Apesar de raramente estarem implicados na etiologia da disfagia, considerando sua alta prevalência, é importante que otorrinolaringologistas e fonoaudiólogos estejam atentos a esse diagnóstico, permitindo tratamento precoce e efetivo para o paciente assistido, melhor prognóstico e menos complicações da disfagia orofaríngea no idoso.

ABSTRACT Anterior cervical osteophytosis is a noninflammatory condition characterized by calcification or ossification of the anterolateral paravertebral ligaments of the cervical spine. It affects 20 to 30% of the elderly, being responsible for 1.6% of the identifiable etiologies of dysphagia in the senile population. In advanced states, dysphagia due to cervical osteophytosis can lead to complications such as malnutrition, weight loss and aspiration pneumonia. This study aims to alert to this diagnosis, enabling early treatment of the condition. The case of a 66-year-old male patient with choking dysphagia for solids and nasal food reflux for 1 year is reported. Fiberoptic Endoscopic Evaluation of Swallowing showed bulging of the posterior pharyngeal wall and, with solid food supply, restriction to the retroflexion of the epiglottis, nasal reflux of the food and a large amount of food residue on the lesion. Cervical spine Computed Tomography identified the presence of anterior cervical osteophytes between the C3 and C6 vertebrae, the largest with anteroposterior length of 12 millimeters, narrowing the air column at the level of the oro- and hypopharynx. The patient was adequately treated with swallowing therapy by speech-language pathologist. The initial treatment strategy for symptomatic osteophytosis should be conservative, usually with a good response to swallowing therapy. Although they are rarely implicated in the etiology of dysphagia, considering its high prevalence, it is important that otolaryngologists and speech-language pathologists are attentive to this diagnosis, allowing early and effective treatment for the assisted patient, better prognosis and fewer complications of oropharyngeal dysphagia in the elderly.

Arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome / 中国骨伤

OBJECTIVE@#To investigate the surgical skills and clinical curative results of arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome.@*METHODS@#From February 2019 to August 2020, 13 patients with ankle instability combined with anteromedial impingement were retrospectively analyzed. There were 10 males and 3 females with age of (40.0±15.1) years old. The course of disease was(44.1±33.2) months. All patients had history of ankle sprain. MRI showed the injury of anterior talofibular ligament. All patients had anteromedial pain and pressing pain when ankle dorsiflexion. All patients were treated with ankle debridement and Brostr?m-Gould surgery under ankle arthroscopic. Postoperative results were evaluated by VAS(visual analogue scale) and AOFAS-AH(American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, AOFAS-AH).@*RESULTS@#All 13 patients completed the surgery successfully with an operative time of 60 to 90 minutes. All the surgical incisions healed by first intention, and no complications such as incision infection, skin necrosis and neurovascular injury. Follow-up time was (18.1±4.7) months. At the latest follow-up, the VAS score was 1.2±1.1, which was significantly lower than the preoperative score 4.8±1.5 (P<0.05);the AOFAS-AH score 94.2±5.1 was significantly higher than the preoperative score 65.5±11.5 (P<0.05). The AOFAS-AH score at the final follow-up ranged from 84 to 100. All patients walked with normal gait without ankle instability or impingement recurrence.@*CONCLUSION@#Ankle anteromedial impingement syndrome combined with ankle instability is easy to be ignored clinically. Such kind of anteromedial impingement syndrome is mostly related to osteophyte at dorsal medial talar neck. Arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome has satisfactory curative effect with safety and minimal injury.

Morphology of dorsal medial talar neck osteophyte and its clinical significance: based on three-dimensional computed tomography / 中华创伤骨科杂志

Objective:To study the morphology of dorsal medial talar neck osteophyte (DMTNO) and its association with anteromedial ankle impingement syndrome (AAIS) using CT 3D reconstruction images.Methods:The present retrospective study included 23 patients with AAIS due to DMTNO (case group) and 23 patients with DMTNO but without AAIS (control group) who had been admitted from February 2019 to June 2021. Multi-slice CT data (DICOM) of DMTNO in both groups were collected and imported into Arigin 3D Pro 3D reconstruction software to reconstruct and observe the 3D morphology of DMTNO. The dorsal convex distance, medial convex distance and anterior convex distance of DMTNO were measured to find their association with AAIS.Results:In the case group, DMTNO clearly showed a flat polyhedral shape with a large base and a small top; in the control group, DMTNO showed various shapes that were different mainly in an irregular top but similar in a large, long and narrow base. The dorsal convex distance [(8.07±2.30) mm] and medial convex distance [(6.70±2.62) mm] in the case group were significantly larger than those in the control group [(3.59±1.10) mm and (1.98±0.93) mm] ( P<0.05), but there was no significant difference between the 2 groups in the anterior convex distance ( P>0.05). Conclusions:The DMTNO leading to AAIS shows a flat polyhedral shape with a large base and a small top. No correlation is found between the anterior convex and AAIS whereas the dorsal convex and medial convex of DMTNO may be closely associated with AAIS.

Hiperostosis esquelética difusa idiopática, una causa infrecuente de disfagia y disfonía

Resumen La hiperostosis esquelética difusa idiopática (DISH) es una enfermedad sistémica caracterizada por la osificación del ligamento longitudinal anterior de la columna. Los pacientes suelen ser asintomáticos o presentar dolor leve o rigidez, sin embargo, cuando afecta la región cervical puede ocasionar disfagia, disfonía o disnea. Presentamos el caso de un paciente de 63 años con disfonía y disfagia en quien los estudios demostraron desplazamiento del aritenoides y colapso del seno piriforme debido a un osteofito a nivel de C4. El paciente presentó mejoría con tratamiento conservador. Realizamos una discusión del caso y una revisión de la literatura sobre diagnóstico y tratamiento de esta patología.

Abstract Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic disease characterized by ossi- fication of the anterior longitudinal ligament of the spine. Patients are usually asympto- matic, or present mild pain or stiffness, however cervical compromise can cause dysphagia, dyspnea and dysphonia. We present the case of a 63-year-old patient with hoarseness and dysphagia. Studies revealed anterior displacement of the arytenoid cartilage and collapse of the pyriform sinus secondary to an osteophyte at C4 level. The patient showed improvement with conservative management. We present a discussion about this case and the available scientific evidence on the diagnosis and treatment of this pathology.

Incisão em T invertido com remoção de osteófitos, no tratamento da unha em pinça / Inverted T Incision with Osteophyte Removal in The Treatment of Pincer Nail

A deformidade da unha em pinça é caracterizada por excessiva curvatura transversal da unha. Uma mulher de 58 anos apresentou-se com queixa de unha em pinça acompanhada de edema e dor no último 1 mês devido ao uso frequente de sapatos estreitos. Foi realizada uma cirurgia para tratar dor, inflamação, interferência no uso de calçados e cosmético, utilizando o método de incisão em T invertido com remoção de osteófitos. Este caso mostrou que a abordagem cirúrgica não foi demorada, apresentando curto tempo de cicatrização, dor mínima e excelente resultado cosmético.

Pincer nail deformity is characterized by excessive transverse over curvature of the nail. A 58-year-old woman came with a complaint of pincer nail accompanied by swelling and pain in the last 1 month due to frequent use of narrow shoes. We performed a surgical intervention indicated to treat pain, inflammation, interference with wearing shoes, and cosmetic embarrassment using an inverted T incision method with osteophyte removal. This case showed that the surgical approach did not require a long time to be conducted, presenting brief healing time, minimal pain, and excellent cosmetic outcome.

Surgical Outcomes of Dysphagia Provoked by Diffuse Idiopathic Skeletal Hyperostosis in the Cervical Spine

PURPOSE: This study aimed to predict the surgical outcomes of diffuse idiopathic skeletal hyperostosis (DISH)-related dysphagia (DISH-phagia) and to evaluate the importance of prevertebral soft tissue thickness (PVST).MATERIALS AND METHODS: In total, 21 surgeries (anterior osteophytectomy or anterior cervical decompression and fixation) were included in this study for DISH-phagia from 2003 to 2019. Clinical outcomes were assessed using the Dysphagia Outcome and Severity Scale (DOSS) preoperatively, at 1 month postoperatively, and last follow up (mean 29.5 months). PVST was measured using lateral plain radiographs. Paired t-test and Spearman's correlation test was used to identify relationships between various PVST indices and DOSS.RESULTS: Comparisons were made from 17 patients out of 21, in which the record had all of three measurements. The narrowest PVST preoperatively was 2.55±0.90 mm, with a DOSS score of 4.47±1.61, and that at 1 month after surgery was 5.02±2.33 mm, with a DOSS score of 6.12±1.32. At last follow up, PVST and DOSS values were 3.78±0.92 mm and 5.82±1.34, and three patients experienced symptom relapse. Significant relationships were found between PVST and DOSS at all time points: before surgery (R=0.702, p<0.001), 1 month after surgery (R=0.539, p=0.012), and last follow up (R=0.566, p=0.020).CONCLUSION: Surgical removal of anterior osteophytes is an effective treatment option for DISH-phagia, and PVST is a useful parameter in DISH-phagia. The goal of DISH surgery should be to remove DISH as much as possible to ensure sufficient PVST postoperatively.

Study on the correlation between the arc height of cervical endplate and osteophyte in posterior margin of intervertebral space / 中国骨伤

OBJECTIVE@#To study the correlation and clinical value of the arc height of upper and lower endplates, the height of intervertebral space and osteophyte of posterior edge of intervertebral space in patients with cervical spondylosis.@*METHODS@#A total of 108 patients with cervical spondylosis who underwent cervical spondylosis surgery from September 2017 to September 2018 were included in the study. Including 48 males with an average age of 52 years (30 to 72) and 60 females with an average age of 54 years (37 to 79). Among them, C of 6 cases, C of 15 cases, C of 32 cases, C of 42 cases, C of 13 cases. X-ray films of cervical spine were taken before and after operation. The images were accessed by PACS (Picture Archiving and Communication Systems) system. The lower and upper endplate arc heights (L, L), intervertebral space height (L), and posterior osteophyte width (L) were measured. Spearman was used to analyze the correlation between them.@*RESULTS@#L was negatively correlated with L (r=-0.34, 0.05), L and L (>0.05).@*CONCLUSION@#The arc height of the lower endplate is negatively correlated with the width of osteophyte in the posterior margin of the intervertebral space. The cervical degeneration degree can be determined by measuring the arc height of the lower endplate, which has guiding significance for the early prevention and treatment of cervical spondylosis.

Association of htra1 and hapln1 gene polymorphism with intervertebral disc degeneration / 中国组织工程研究

BACKGROUND: Studies have found that single nucleotide polymorphism genotypes in the HTRA1 gene promoter region are associated with intervertebral disc degeneration, while HAPLN1 is associated with osteoarthritis caused by intervertebral disc degeneration. OBJECTIVE: To explore the role of human secretory serine protease HTRA1 and the key group of extracellular matrix HAPLN1 in the pathogenesis of intervertebral disc degeneration. METHODS: This study included 498 postmenopausal female subjects who underwent a physical examination at Dingzhou People’s Hospital from April 2015 to December 2018. TaqMan PCR was used to detect HTRA1 gene promoter rs11200638 single nucleotide polymorphism and HAPLN1 gene 5' flanking rs975563, intron 1 rs10942332, intron 2 rs179851 and intron 4 rs4703570 single nucleotide polymorphism in 498 postmenopausal Chinese women. The correlation between the HTRA1orHAPLN1 gene polymorphisms and the radiographic features of spinal disc degeneration was analyzed. The trial has been approved by the Ethics Committee of Dingzhou People’s Hospital. RESULTS AND CONCLUSION: Among the 498 subjects with the HTRA1 gene rs11200638 single nucleotide polymorphism, 178 were GG homozygotes, 222 were GA heterozygotes, and 98 were AA homozygotes. We compared the parameters of intervertebral disc degeneration in subjects with at least one G allele (GG+GA, n=400) and without G allele (AA, n=98). In HTRA1 gene rs11200638 single nucleotide polymorphism, the score on intervertebral space stenosis in the subjects with GG+GA allele genome was lower than that in the subjects with AA allele (P < 0.001). With the increase of the score on intervertebral space stenosis, the proportion of the subjects with AA alleles increased (P ≤ 0.001). Among the 498 subjects with single nucleotide polymorphisms of the HAPLN1 gene, 137 were homozygous for TT, 230 were heterozygous for CT, and 131 were homozygous for CC. Intervertebral disc degeneration parameters of CC+TT allele (n=361) and TT allele (n=137) were compared. In the HAPLN1 gene, there was a significant difference between the CC+TT and TT alleles of the rs179851 single nucleotide polymorphism in osteophyte formation and intervertebral space stenosis (P < 0.01). Among the HAPLN1 gene rs179851 single nucleotide polymorphisms, the proportion of subjects with TT alleles and intervertebral space stenosis ≥ 6 points increased (P < 0.05). With an increase in osteophyte formation score, the proportion of subjects with TT allele increased (P < 0.001). These results reveal that HTRA1 and HAPLN1 genetic variations at specific genetic loci are associated with intervertebral disc degeneration.

Temporarily Aggravated Dysphagia Following Osteophytectomy and Fixation in a Patient with Cervical Osteophyte / 대한연하장애학회지

An anterior cervical osteophyte is one of the causes of dysphagia. Surgical treatment is one of the treatment options available, and previous studies have suggested that it is an immediate and effective treatment. This paper reports a case of temporarily aggravated dysphagia after surgical treatment in a patient with anterior cervical osteophyte. A 75-year-old male complained of dysphagia for one year. A videofluoroscopic swallowing study (VFSS) revealed anterior cervical osteophytes at the C3 and C4 level, which resulted in decreased epiglottic folding and partial obstruction of the bolus passage. After he underwent osteophytectomy and anterior fixation, the post-operative VFSS showed an aggravation of dysphagia with prevertebral soft tissue edema. The major cause of dysphagia was attributed to the limitation of movement of the posterior pharyngeal wall and upper esophageal sphincter due to the increased prevertebral soft tissue thickness. In conclusion, surgery should be considered when a severe dysphagia is persistent after adequate conservative treatment in patients with dysphagia due to anterior cervical osteophytes, and patients at high risk of postoperative dysphagia might require swallowing rehabilitation.

The characteristics of osteophyte around lumbar vertebral foramina associated with spinal stenosis / 대한해부학회지

Spinal stenosis most commonly occurs on lumbar vertebrae because of degenerative changes. This research studied the characteristics of osteophyte development in lumbar vertebrae foramina and association of osteophyte development with lumbar spinal stenosis. The total number of all levels of lumbar spines of subjects was 179 from 31 to 90 years of age. The vertebral foramen was divided into six zones. The prevalence and measurements of the length of osteophytes in the vertebral foramina were obtained. The prevalence and length of osteophytes in the posterior body zone were higher than the laminal zone, and higher than the pedicular zone, respectively. In each zone, the highest prevalence of osteophytes was at L5, except for the inferior posterior body zone that the highest prevalence is at L4. The length of osteophyte was also in same direction as the prevalence. The prevalence of osteophytes among six zones of each level were compared, and found, in L1 to L4, the inferior posterior body zone generally had the highest prevalence, except in L5, the superior posterior body zone had the highest prevalence. Moreover, prevalence, as well as length, of osteophytes in lumbar vertebral foramina, of all levels, was positively associated with age. Vertebral osteophytes can develop beginning at 31 years of age. In conclusion, posterior body of L4 and L5 had the highest prevalence of osteophyte formation, thus, these area had the highest probability to cause spinal stenosis.

Degenerative Osteophyte Causing Acute Locked Knee in a Young Man: A Case Report

Abstract@#Acute locked knee is usually caused by mechanical blockage. We report an unusual case of a locked knee due to tibial osteophyte in a young man following a sport injury. To the best of our knowledge, there has been no previous report describing the same etiology. This case report emphasizes the need for thorough history taking and careful assessment to aid us in the diagnosis. The findings made by arthroscopy confirmed our diagnosis.

Comparing two surgical treatment methods for mucous cysts of the distal interphalangeal joint in elderly patients / 中华老年医学杂志

Objective To contrast and compare two surgical treatments for mucous cysts of the distal interphalangeal joint.Methods Clinical data from April 2004 to January 2016 were retrospectively analyzed.Patients who underwent tumor excision,osteophyte excision,and local flap coverage were assigned into a flap group(n=16),while patients who received osteophyte excision,cyst pedicle resection,and cystic fluid drainage were assigned into a simple osteophyte resection group(n=17).Procedure time,pain,satisfaction score,and hand function were compared between the two groups.Results Patients in the flap group were followed up for 14 to 28 months(mean=19.5 months);the simple osteophyte resection group for 15 to 26 months(mean=20.5 months).There was no recurrence in either group.The rate of excellent efficacy was 81.25 ％ (13/16)for the skin flap group and 82.35 ％ (14/17) for the simple osteophyte resection group,and the difference was not statistically significant(x2=0.007,P ＞ 0.05).Pain relief was achieved in both groups after operation,and the postoperative satisfaction score was higher than the pre-operation score.There was no statistical difference in pre operation pain and satisfaction scores (t 0.14 and 0.35,both P ＞ 0.05),no statistical difference in postoperative pain scores(t =-0.09,P ＞ 0.05),but a statistically significant difference in postoperative satisfaction scores (t =-4.15,P ＜ 0.05) between the two groups.Conclusions Two surgical treatments of mucous cysts can achieve satisfactory aesthetic and clinical outcomes.The simple osteophyte resection method is characterized by a short procedure time and a high level of postoperative satisfaction,but it requires training in microsurgery.Local flap coverage is simple and suitable for lower level hospitals where staff surgeons may lack microsurgical skills,but it may result in certain minor injuries.

Diagnóstico diferencial de hernia discal / Diagnostic differences for disc herniation

Disc herniation is a frequent pathology in the radiologist's daily practice. There are different pathologies that can simulate a herniated disc from the clinical and especially the imaging point of view that we should consider whenever we report a herniated disc. These lesions may originate from the vertebral body (osteophytes and metastases), the intervertebral disc (discal cyst), the intervertebral foramina (neurinomas), the interapophyseal joints (synovial cyst) and from the epidural space (hematoma and epidural abscess).

La hernia discal es una patología frecuente en la práctica diaria del radiólogo. Hay distintas patologías que pueden simular una hernia discal desde el punto de vista clínico y especialmente imagenológico que debemos considerar cada vez que informamos una hernia discal. Estas lesiones pueden provenir del cuerpo vertebral (osteofitos y metástasis), del disco intervertebral (quiste discal), de los forámenes intervertebrales (neurinomas), de las articulaciones interapofisiarias (quiste sinovial) y desde el espacio epidural (hematoma y absceso epidural).

Effectiveness of digital subtraction radiography in detecting artificially created osteophytes and erosions in the temporomandibular joint

PURPOSE: Erosions and osteophytes are radiographic characteristics that are found in different stages of temporomandibular joint (TMJ) osteoarthritis. This study assessed the effectiveness of digital subtraction radiography (DSR) in diagnosing simulated osteophytes and erosions in the TMJ. MATERIALS AND METHODS: Five intact, dry human skulls were used to assess the effectiveness of DSR in detecting osteophytes. Four cortical bone chips of varying thicknesses (0.5 mm, 1.0 mm, 1.5 mm, and 2.0 mm) were placed at the medial, central, and lateral aspects of the condyle anterior surface. Two defects of varying depth (1.0 mm and 1.5 mm) were created on the lateral, central, and medial poles of the condyles of 2 skulls to simulate erosions. Panoramic images of the condyles were acquired before and after artificially creating the changes. Digital subtraction was performed with Emago dental image archiving software. Five observers familiar with the interpretation of TMJ radiographs evaluated the images. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic accuracy of the imaging methods. RESULTS: The area under the ROC curve (Az) value for the overall diagnostic accuracy of DSR in detecting osteophytic changes was 0.931. The Az value for the overall diagnostic accuracy of panoramic imaging was 0.695. The accuracy of DSR in detecting erosive changes was 0.854 and 0.696 for panoramic imaging. DSR was remarkably more accurate than panoramic imaging in detecting simulated osteophytic and erosive changes. CONCLUSION: The accuracy of panoramic imaging in detecting degenerative changes was significantly lower than the accuracy of DSR (P<.05). DSR improved the accuracy of detection using panoramic images.

Diagnosis and Treatment of Early Ankle Osteoarthritis / 대한족부족관절학회지

The incidence of arthritis in the ankle is relatively low compared to other joints. On the other hand, it receives a lot of pressure per unit area, is vulnerable to damage, and arthritis can arise after trauma. Early ankle arthritis can be considered a case of osteophyte subchondral sclerosis without narrowing of the joint space. Conservative treatment, such as weight control, insole use, drug use, and injection therapy for early ankle arthritis, is effective and can be considered before surgical treatment. Nevertheless, if pain is persistent, surgical treatment to remove bony spurs is effective. Ensuring that there is no other cause of pain when deciding whether to perform an operation is very important.

A histologic study on osteophytes in severe osteoarthritis by Masson staining and immunohistochemical staining for collagen type Ⅱ / 实用医学杂志

Objective To establish a histological classification system for osteophytes by Masson staining and immunohistochemical staining for collagen type II. Methods Osteophytes were collected from knee joints in os?teoarthritis patients after joint replacement surgery. To develop an osteophyte classification ,serial tissue sections were identified using histological(hematoxylin and eosin,Masson ' s trichrome,toluidine blue)and immunohisto?chemical staining(collagen typeⅡ). Joint function was assessed by WOMAC score and radiological findings was measured by Kellgren?Lawrence grading. The consistency between the osteophyte classification and WOMAC/Kell?gren?Lawrence grading were evaluated. Results 31 patients and 101 osteophyte samples were included in this study. Based on the histological and immunohistochemical evaluation,osteophytes can be divided into type A (4.9%),type B(4.0%),type C(26.7%)and type D(64.4%). This histological classification system had better consistency with joint function score(χ2 = 0.108,P = 0.947)and Kellgren?Lawrence grading(χ2 = 3.205,P =0.201). Conclusions This trial establishes a histological classification system for osteoarthritis osteophytes ,types A and B indicating early osteophyte and types C and D indicating advanced osteophyte. The system is helpful in clini?cal and basic research on osteoarthritis.

Disfagia devido a osteoitose cervical: relato de caso / Dysphagia due to cervical osteophytosis: case report

Doenças degenerativas na coluna cervical são comuns nos pacientes idosos. Os autores apresentam caso de paciente do sexo feminino, 44 anos, com quadro de disfagia progressiva relacionada à osteofitose cervical anterior em (C5-C6 e C6-C7). Esofagograma mostrou a compreensão esofágica pelos osteófitos anteriores. O tratamento realizado foi brocagem dos osteófitos, discectomia cervical em dois níveis e artrodese cervical, resultando na remissão completa do sintoma. Embora seja uma causa de disfagia, osteófito deve ser incluído como diagnóstico diferencial pois é uma causa tratável e reversível do sintoma.

Degenerative diseases of the cervical spine are common in elderly patients. The authors present a case report of female, 44 years old, with progressive dysphagia due to anterior cervical osteophytes (C5-C6 and C6-C7). Esophagogram showed esophageal compression by anterior osteophytes. The treatment was removal of osteophytes by drill, cervical discectomy on two levels and cervical arthrodesis, resulting in complete remission of symptoms. Although it is an un-common cause of dysphagia, osteophytes should be included in the differential diagnosis because it is a reatable and reversible cause of the symptom.

Spontaneous Rupture of the Second and Third Extensor Digitorum Longus Tendons Caused by Osteophyte of the Tarsometatarsal Joint: A Case Report / 대한족부족관절학회지

Spontaneous rupture of the extensor tendon has been reported in association with predisposing inflammatory conditions including rheumatoid arthritis, diabetes, trauma, tophaceous gout, and steroid injection. The authors experienced a case of spontaneous rupture of the extensor digitorum longus tendons caused by an osteophyte of the tarsometatarsal joint in a patient with rheumatoid arthritis. The authors stress that aggressive treatment including surgery could be considered for prevention of spontaneous tendon rupture in a patient with predisposing conditions despite an asymptomatic spur.

Intrinsic Vertebral Markers for Spinal Level Localization in Anterior Cervical Spine Surgery: A Preliminary Report

STUDY DESIGN: Prospective clinical study. PURPOSE: To observe the usefulness of anterior cervical osteophytes as intrinsic markers for spinal level localization (SLL) during sub-axial cervical spinal surgery via the anterior approach. OVERVIEW OF LITERATURE: Various landmarks, such as the mandibular angle, hyoid bone, thyroid cartilage, first cricoid ring, and C6 carotid tubercle, are used for gross cervical SLL; however, none are used during cervical spinal surgery via the anterior approach. We present our preliminary assessment of SLL over anterior vertebral surfaces (i.e., intrinsic markers) in 48 consecutive cases of anterior cervical spinal surgeries for the disc-osteophyte complex (DOC) in degenerative diseases and granulation or tumor tissue associated with infectious or neoplastic diseases, respectively, at an ill-equipped center. METHODS: This prospective study on patients undergoing anterior cervical surgery for various sub-axial cervical spinal pathologies aimed to evaluate the feasibility and accuracy of SLL via intraoperative palpation of disease-related morphological changes on anterior vertebral surfaces visible on preoperative midline sagittal T1/2-weighted magnetic resonance images. RESULTS: During a 3-year period, 48 patients (38 males,10 females; average age, 43.58 years) who underwent surgery via the anterior approach for various sub-axial cervical spinal pathologies, including degenerative disease (n= 42), tubercular infection (Pott's disease; n=3), traumatic prolapsed disc (n=2), and a metastatic lesion from thyroid carcinoma (n=1), comprised the study group. Intrinsic marker palpation yielded accurate SLL in 79% of patients (n=38). Among those with degenerative diseases (n=42), intrinsic marker palpation yielded accurate SLL in 76% of patients (n=32). CONCLUSIONS: Intrinsic marker palpation is an attractive potential adjunct for SLL during cervical spinal surgeries via the anterior approach in well-selected patients at ill-equipped centers (e.g., those found in developing countries). This technique may prove helpful when radiographic visualization is occasionally inadequate.
