Thoracic ligamentum flavum ossification: a rare cause of spinal cord injury without tomographic evidence of trauma in a Caucasian patient. Case report and literature review.

INTRODUCTION: Acute spinal cord injury without tomographic evidence of vertebral fracture or dislocation in patients post trauma can represent a diagnostic challenge for the treating physician. The ossification of thoracic ligamentum flavum has been widely published as a cause of thoracic myelopathy, however its association with acute traumatic spinal cord injury is limited to isolated cases. CASE PRESENTATION: we report a Caucasian 37-year-old man who suffered a high-energy thoracolumbar spine trauma in a motorcycle accident with acute paraplegia. He presented ossification of the ligamentum flavum between the thoracic vertebrae T10 and T11 with a decrease in the diameter of the vertebral canal as the only pathological finding. We treated the patient with early surgical release before 72 h of trauma. We performed a posterior approach with hemilaminectomy and T10-T11 flavectomy. Arthrodesis was done with T10-T11 pedicle screws. Postoperative neurological status improved from ASIA Impairment Scale (AIS) A to C with severe functional dependence. DISCUSSION: Ossification of the ligamentum flavum should be considered in the differential diagnosis in patients presenting with acute traumatic spinal cord injury without tomographic evidence of trauma. A proper diagnosis in time is the key to decision making and treatment of spinal cord injury. Especially in adult patients, we must consider nontraumatic associated factors that could be involved in the spinal cord injury mechanism, such as ossification of the ligamentum flavum.

Low-Dose Aspirin Administered for Venous Thromboembolism Prophylaxis Reduces the Incidence of Heterotopic Ossification in Total Joint Arthroplasty.

BACKGROUND: Heterotopic ossification (HO) is a common complication following total joint arthroplasty (TJA). However, the pathophysiology of HO is not entirely understood. Inflammation may play a significant role in the pathogenesis of HO as nonsteroidal anti-inflammatory drugs are effective in the prevention of HO. The purpose of this study is to examine if aspirin (ASA), when used as venous thromboembolism (VTE) prophylaxis, influenced the rate of HO formation following TJA. METHODS: We queried our longitudinally maintained database to identify all patients who underwent primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) for osteoarthritis between January 2016 and June 2018 with at least 3-month radiographic follow-up. In total, 1238 THAs and 1051 TKAs were included for analysis. Radiographs were reviewed and HO formation graded according to the Brooker classification. Patient demographic and VTE prophylaxis data were collected and reviewed for accuracy. Univariate and multivariate analysis was performed to evaluate the effect of ASA on HO formation. RESULTS: The overall rate of HO was 37.5% after THA and 17.4% after TKA. Patients receiving ASA were less likely to develop HO after THA (34.8% vs 45.5%; P < .001), as well as HO after TKA (13.4% vs 18.4%; P = .047) compared to patients receiving non-ASA VTE prophylaxis. The rate of HO formation trended to be lower, albeit not statistically significantly, in patients receiving low-dose ASA (81 mg) vs high-dose ASA (325 mg). CONCLUSION: Patients undergoing primary TJA receiving ASA for VTE prophylaxis were less likely to develop HO compared to patients who were administered non-ASA VTE prophylaxis.

Osificación heterotópica de cadera asociada a pancreatitis aguda severa: reporte de un caso / Hip heterotopic ossification associated with severe acute pancreatitis: a case report

La osificación heterotópica (OH), es la formación anormal de hueso maduro dentro de tejidos blandos extra esqueléticos donde normalmente no existe tejido óseo. Varias formas de OH han sido descritas de acuerdo a su presentación clínica, localización y ocurrencia progresiva o aislada. Su presentación en pacientes sometidos a inmovilización prolongada en el contexto de coma farmacológicamente inducido, en ausencia de lesiones del sistema nervioso central, es poco habitual. Presentamos el caso de una paciente de 40 años, sexo femenino, sin antecedentes mórbidos, que presenta episodio de pancreatitis aguda grave, manejada en UCI. Producto de lo anterior, requiere coma farmacológicamente inducido por 3 meses y hospitalizaciones reiteradas y prolongadas durante los 10 meses siguientes. Durante 3 años desde la resolución de su cuadro inicial evoluciona con alteración progresiva de la marcha y rigidez de la extremidad inferior derecha, sin eventos traumáticos durante ese período. Se objetiva mediante radiografía y TAC foco de OH coxofemoral derecha. Se resuelve de forma quirúrgica y biopsia de pieza operatoria confirma el diagnóstico. La paciente logra buena recuperación posterior. NIVEL DE EVIDENCIA: IV

Heterotopic ossification (HO) is the abnormal formation of mature bone within extraskeletal soft tissues where bone does not exist. Various presentation of HO have been described according to the clinical settings and location of the lesions, and progressive or isolated occurrence. A rare form of presentation occurs in induced coma patients with long-term immobilization and without central nervous system injuries. We present the case of a 40 years old female patient, without previous morbidity, who develop a severe acute pancreatitis. The patient requires an intensive care unit management (ICU) and a 3-month pharmacology induced coma and reiterative and prolonged hospitalizations during the next 8 months. During 3 years after resolution of her base disease, patient develops a progressive step claudication and a hip rigidity in adduction and external rotation. A coxofemoral HO focus is confirmed by radiology and CT. A surgical treatment of HO was performed, and the initial diagnose confirmed by anatomic pathology after biopsy of the injury. Patient had a favorable outcome.

A Prospective Evaluation of Early Postoperative Complications After Distal Biceps Tendon Repairs.

PURPOSE: The reported incidence of postoperative complications after distal biceps tendon repairs (DBTRs) has been determined largely by retrospective studies. We hypothesized that a large prospective cohort study of DBTRs would demonstrate increased complication rates relative to existing literature values. Secondarily, we hypothesized that most complications would be transient and self-limiting, regardless of the surgical technique employed for the repair. METHODS: Consecutive patients undergoing acute, primary DBTR from July 2016 to December 2017 were enrolled. The repair technique, postoperative protocol, and follow-up intervals were determined by the individual surgeons' protocols. Demographic information, surgical data, and complications were tabulated prospectively. Exclusion criteria included chronic DBTRs, secondary DBTRs requiring allograft, DBTRs of partial tears, and postoperative follow-up of less than 12 weeks. We included 212 repairs performed by 37 orthopedic surgeons in 3 different subspecialties. RESULTS: Sixty-five patients (30.7%) had 73 complications. Fifty patients (44.6%) in the 1-incision group experienced complications compared with 15 (15.0%) in the 2-incision group. Sixty patients (28.3%) developed a minor complication. Fifty-seven patients (26.9%) had sensory neurapraxias, 47 after a 1-incision procedure and 10 after a 2-incision procedure, a statistically significant difference. Of the patients with neurapraxias, 94.7% were resolved or improving at the time of the latest follow-up. Five patients (2.4%) developed a major complication, defined as a return to the operating room in the postoperative period due to deep infection or rerupture. CONCLUSIONS: The complication rate after DBTR appears to be higher than 2 other retrospective studies and is predominantly in the form of transient neurapraxias. This study confirms that there is a higher complication rate in 1-incision techniques as compared with 2-incision techniques. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Auditory brainstem implant in postmeningitis totally ossified cochleae.

INTRODUCTION: An auditory brainstem implant (ABI) is an option for auditory rehabilitation in patients with totally ossified cochleae who cannot receive a conventional cochlear implant. OBJECTIVE: To evaluate the outcomes in audiometry and speech perception tests after the implantation of an ABI via the extended retrolabyrinthine approach in patients with postmeningitis hearing loss. MATERIALS AND METHODS: Ten patients, including children and adults, with postmeningitis hearing loss and bilateral totally ossified cochleae received an ABI in a tertiary center from 2009 to 2015. The extended retrolabyrinthine approach was performed in all the patients by the same surgeons. A statistical analysis compared pure tonal averages and speech perception tests before and at least 12 months after the ABI activation. RESULTS: Eight patients (80%) showed improvements in tonal audiometry and the word and vowel perception tests after an average follow-up of 3.3 years. Two patients recognized up to 40% of the closed-set sentences without lip-reading. Two patients had no auditory response. CONCLUSIONS: The ABI improved hearing performance in audiometry and speech perception tests in cases of postmeningitis hearing loss. The extended retrolabyrinthine approach is a safe surgical option for patients with postmeningitis hearing loss and bilateral totally ossified cochleae.

[Idiopathic pulmonary hemosiderosis with dendriform pulmonary ossification].

Pulmonary ossification is a rare and usually asymptomatic finding reported as incidental in lung biopsies. Similarly, idiopathic pulmonary hemosiderosis is a rare cause of pulmonary infiltrates. We report the case of a 64-year old man with chronic respiratory symptoms in whom these two histopathological findings converged.

Eagle syndrome: a narrative review / Síndrome de Eagle: una revisión narrativa

Abstract: painful disorders in the maxillofacial region are common in dental practice. Most of these conditions are not properly diagnosed because of inadequate knowledge of craniofacial and cervico-pharyngeal syndromes such as Eagle Syndrome. The aim of this review is to describe the general aspects, diagnosis and treatment of Eagle syndrome. Eagle syndrome or stylohyoid syndrome was first described by Watt W. Eagle in 1937. It was defined as orofacial pain related to the elongation of the styloid process and ligament stylohyoid calcification. The condition is accompanied by symptoms such as dysphonia, dysphagia, sore throat, glossitis, earache, tonsillitis, facial pain, headache, pain in the temporomandibular joint and inability to perform lateral movements of the neck. Diagnosis and treatment of Eagle syndrome based on symptoms and radiographic examination of the patient will determine the need for surgical or nonsurgical treatment. Eagle syndrome is a complex disorder demanding a thorough knowledge of its signs and symptoms to make a correct diagnosis and provide an appropriate subsequent treatment. Disseminating information about this syndrome among medical-dental professionals is essential to provide adequate dental care to patients.

Resumen: en la práctica odontológica, es frecuente encontrar alteraciones con sintomatología dolorosa en la región maxilofacial, las cuales no son apropiadamente diagnosticadas, a causa del desconocimiento de síndromes craneofaciales y cervicofaríngeos, como el Síndrome de Eagle. El objetivo de esta revisión es describir los aspectos generales, diagnóstico y tratamiento del Síndrome de Eagle. El Síndrome de Eagle o estilalgia es la entidad nosológica, descrita por Watt W. Eagle en 1937, definida como aquel dolor orofacial relacionado con la elongación de la apófisis estiloides y calcificación del ligamento estilohioideo; el cual está acompañado de síntomas como: disfonía, disfagia, dolor faríngeo, glositis, otalgia, tonsilitis, dolor facial, cefalea, odinofagia, dolor en la articulación temporomandibular e imposibilidad de realizar movimientos laterales del cuello. El diagnóstico y tratamiento del Síndrome de Eagle está basado en la sintomatología y el examen radiográfico del paciente, lo cual determinará el tratamiento quirúrgico o no quirúrgico. El Síndrome de Eagle es una patología compleja que requiere un conocimiento amplio de sus signos y síntomas, para establecer un correcto diagnóstico y posteriormente un adecuado tratamiento. Para ello, es necesario difundir la información sobre este síndrome entre los profesionales médico-odontológico y así brindar una atención adecuada a cada uno de los pacientes.

Surgical Hip Dislocation for the Treatment of Intra-Articular Injuries and Hip Instability Following Traumatic Posterior Dislocation in Children and Adolescents.

BACKGROUND: Traumatic posterior hip dislocation in children is a rare injury that typically is treated with closed reduction. Surgical treatment is typically recommended for nonconcentric reduction with joint space asymmetry with entrapped labrum or an osteochondral fragment. The surgical hip dislocation (SHD) approach allows for full assessment of the acetabulum and femoral head and has been our preferred surgical strategy. The purpose of this study was to (1) describe the intra-articular pathologic findings seen at the time of SHD; and (2) to investigate hip pain, function, and activity level of a cohort of children and adolescents after open treatment of a posterior hip dislocation using the SHD approach. METHODS: Following IRB approval, 23 patients who sustained a traumatic posterior hip dislocation between January 2009 and December 2013 were identified. In 8/23 (34.8%) patients there was evidence of nonconcentric reduction after closed treatment and surgical treatment was performed using the SHD approach. Seven male and 1 female (mean age, 11.2 y; range, 6 to 14.6 y) were followed for an average of 28 months (range, 13 to 67 mo). The modified Harris Hip Score (mHHS) and the University of California Los Angeles activity score assessed clinical hip outcome and activity level at minimum of 1 year after surgery. RESULTS: Six patients were treated after an acute trauma, whereas 2 were treated after recurrent dislocations. Five patients were involved in motor vehicle accidents and 3 in sports-related injuries. Intraoperative findings include posterior labral avulsion in all patients, fracture of the cartilaginous posterior wall (n=3), and femoral head chondral injuries (n=5) and fracture (n=1). The labral root was repaired using suture anchor technique in 7/8 patients and resected in 1. In 2 patients, labral repair was complemented by screw fixation of the posterior wall. All but one patient (mHHS=94) reported maximum mHHS. The University of California Los Angeles activity score was 10 for 5/8 patients and 7 in 3 patients. No case of femoral head osteonecrosis was noted. One patient developed an asymptomatic heterotopic ossification. CONCLUSIONS: When open reduction is recommended for the treatment of intra-articular pathologies and hip instability following traumatic dislocation of the hip in children and adolescents, the SHD is an excellent approach that allows surgical correction of the damaged bony and soft-tissue structures including repair of the capsule-labral complex, and reduction and internal fixation of the cartilaginous posterior wall and femoral head fractures. LEVEL OF EVIDENCE: Level IV.

Tuberculosis osteoarticular y osificaciones heterotópicas: reporte de un caso / Heterotopic ossification and osteoarticular tuberculosis: case report

La osificación heterotópica es una condición patológica que conduce al desarrollo de hueso en el tejido blando. En la piel se denomina osteoma cutis. Estas lesiones se clasifican en primarias o secundarias. Las causas secundarias constituyen el 85% y son consecuencia de enfermedades inflamatorias, infecciones, tumores, traumatismos, lesiones de médula espinal y cirugías. Si bien la osificación heterotópica es benigna e infrecuente, puede ser una enfermedad debilitante que, asociada a dolor y rigidez, provoque mayor comorbilidad en relación con la enfermedad que la desencadenó. Comunicamos el caso de un paciente que padeció osteoma cutis asociado a tuberculosis osteoarticular

Heterotopic ossification is a patologic condition that leads bone formation in soft tissue. In particular, osteoma curtis, which can be primary or secundary, occurs when ossification if found in the skin. Secondary lessions account 85% of the cases described and they are by inflammatory diseases, infections, tumors, traumas, spinal cord lesions and surgeries. Whereas heterotopic ossification is benign and rare, it may result in wasting sickness that in combination with pain and stiffness, adding comorbidity to the disease that triggers. We report here a patient suffering osteomas cutis and osteoarticular tuberculosis. (AU)

Influence of transcutaneous electrical stimulation on heterotopic ossification: an experimental study in Wistar rats

Heterotopic ossification (HO) is a metaplastic biological process in which there is newly formed bone in soft tissues, resulting in joint mobility deficit and pain. Different treatment modalities have been tried to prevent HO development, but there is no consensus on a therapeutic approach. Since electrical stimulation is a widely used resource in physiotherapy practice to stimulate joint mobility, with analgesic and anti-inflammatory effects, its usefulness for HO treatment was investigated. We aimed to identify the influence of electrical stimulation on induced HO in Wistar rats. Thirty-six male rats (350-390 g) were used, and all animals were anesthetized for blood sampling before HO induction, to quantify the serum alkaline phosphatase. HO induction was performed by bone marrow implantation in both quadriceps of the animals, which were then divided into 3 groups: control (CG), transcutaneous electrical nerve stimulation (TENS) group (TG), and functional electrical stimulation (FES) group (FG) with 12 rats each. All animals were anesthetized and electrically stimulated twice per week, for 35 days from induction day. After this period, another blood sample was collected and quadriceps muscles were bilaterally removed for histological and calcium analysis and the rats were killed. Calcium levels in muscles showed significantly lower results when comparing TG and FG (P<0.001) and between TG and CG (P<0.001). Qualitative histological analyses confirmed 100% HO in FG and CG, while in TG the HO was detected in 54.5% of the animals. The effects of the muscle contractions caused by FES increased HO, while anti-inflammatory effects of TENS reduced HO.

Heterotopic ossification in civilians with lower limb amputations.

OBJECTIVES: To report the incidence of symptomatic heterotopic ossification (HO) in a defined civilian amputee population, describe its characteristics, and compare these findings to published data in military amputees. DESIGN: Retrospective chart analysis from July 1998 to July 2009. SETTING: Ambulatory amputee clinic within a large university medical center. PARTICIPANTS: Adults with lower limb amputation (N=158). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Patients with symptomatic HO confirmed by radiographs. RESULTS: A total of 261 patients were evaluated; 158 met inclusion criteria, with 59% having traumatic etiology, 18% vascular etiology, 22% infection, and 1% tumor. Symptomatic HO was diagnosed in 36 (22.8%) patients, and 94% patients had mild HO on radiographic scoring. Rate of HO in amputations related to trauma was not increased compared with those of other etiologies. Surgical resection of the ectopic bone was required in 4 (11%) patients. CONCLUSIONS: HO is seen commonly after civilian lower limb amputation regardless of etiology. The prevalence was less than that observed in previous reports from military populations. This is the first report estimating the prevalence of HO in adult civilian amputees.

Experimental model of heterotopic ossification in Wistar rats

Heterotopic ossification (HO) is a metaplastic biological process in which there is newly formed bone in soft tissues adjacent to large joints, resulting in joint mobility deficit. In order to determine which treatment techniques are more appropriate for such condition, experimental models of induced heterotopic bone formation have been proposed using heterologous demineralized bone matrix implants and bone morphogenetic protein and other tissues. The objective of the present experimental study was to identify a reliable protocol to induce HO in Wistar rats, based on autologous bone marrow (BM) implantation, comparing 3 different BM volumes and based on literature evidence of this HO induction model in larger laboratory animals. Twelve male Wistar albino rats weighing 350/390 g were used. The animals were anesthetized for blood sampling before HO induction in order to quantify serum alkaline phosphatase (ALP). HO was induced by BM implantation in both quadriceps muscles of these animals, experimental group (EG). Thirty-five days after the induction, another blood sample was collected for ALP determination. The results showed a weight gain in the EG and no significant difference in ALP levels when comparing the periods before and after induction. Qualitative histological analysis confirmed the occurrence of heterotopic ossification in all 12 EG rats. In conclusion, the HO induction model was effective when 0.35 mL autologous BM was applied to the quadriceps of Wistar rats.

Risk factors of heterotopic ossification in traumatic spinal cord injury.

OBJECTIVE: Heterotopic ossification (HO) is a complication of the spinal cord injury (SCI). It can result in anchylosis, harming the rehabilitation and quality of life. Previous publications had not elucidated the relation between possible independent variables, the aim of this study. METHOD: From 230 patients with SCI, admitted in 1998 at Hospital SARAH Brasilia, 33 with HO (14.3%; CI95% 10.1-19.6) were compared with 33 controls. The risk factors had been tested in bivariate analysis and in a model of logistic regression. RESULTS: Spasticity (odds ratio=3.8; CI95% 1.15-12.30), number of pressure ulcers (2.1; CI95% 1.08-3.89) and time lapsed since the injury (1.1; CI95% 1.02-1.24) were independently associated with HO. There was a confounder effect among these variables, without interaction. CONCLUSION: Spasticity, pressure ulcer and time of injury are associated with HO in spinal cord injury. The first two factors can be prevented and treatable.
