Eficacia y seguridad a largo plazo del polimetilmetacrilato (PMMA) en pacientes osteoporóticos tratados mediante vertebroplastia percutánea / Long-term efficacy and safety of polymethylmethacrylate (PMMA) in osteoporotic patients treated by percutaneous vertebroplasty

OBJETIVO: Actualmente, existen pocos datos sobre la influencia a largo plazo del polimetilmetacrilato (PMMA) en la integridad de los cuerpos vertebrales tras la vertebroplastia percutánea (VP). Resulta de interés investigar la posible relación entre esta técnica y la aparición con el tiempo de fenómenos de osteólisis o la fragmentación del cemento en las vértebras intervenidas. El objetivo de este trabajo fue investigar si, a largo plazo, existe una pérdida de efectividad y/o seguridad de la VP con PMMA. MATERIAL Y MÉTODOS: Se analizaron radiografías de pacientes intervenidos correspondientes al post-operatorio inmediato y al estudio radiológico más reciente (VP hace más de 15 años). Con ambos estudios radiológicos, describimos: la altura del cuerpo vertebral, la angulación de platillos y la presencia de osteólisis alrededor del cemento en el tiempo. RESULTADOS: Un total de 7 pacientes intervenidos mediante VP con PMMA hace 15 o más años accedieron a realizarse una nueva radiografía en nuestro Centro. Tras el análisis de sus imágenes post-operatorias (inmediatas y a 15 ó más años de la cirugía), no se observó en ninguna de las vértebras intervenidas pérdida de altura del cuerpo vertebral cementado, diferencias de angulación en los platillos, presencia de osteólisis alrededor del cemento o fragmentación del PMMA inyectado. CONCLUSIÓN: El PMMA inyectado en el cuerpo vertebral mantiene una situación estable en el tiempo (más de 15 años). No se observan cambios en la interfaz hueso-PMMA, osteólisis y/o cambios en la altura de los cuerpos vertebrales en los casos analizados

OBJETIVE: Currently, there are limited data on the long-term influence of polymethylmethacrylate (PMMA) on the integrity of vertebral bodies after percutaneous vertebroplasty (PVP). Interesting investigation is being carried out into the possible relationship between this technique and the appearance over time of osteolytic phenomena or cement fragmentation in the intervened vertebrae. The objective of our study was to investigate whether there is a loss of effectiveness and/or safety of PVP with PMMA in the long term. MATERIAL AND METHOD: X-rays were analyzed of intervened patients corresponding to the immediate post-operative and the most recent radiological study (PVP more than 15 years previous). With both radiological studies, we describe: the height of the vertebral body, the angulation of lamellar plates and osteolytic presence around the cement over time. RESULTS: A total of 7 patients operated by PVP with PMMA 15 or more years earlier agreed to have a new radiograph in our center. After the analysis of their post-operative images (immediate and 15 or more years after surgery), no loss of height of the cemented vertebral body, differences in angulation in the lamellar plates, presence of osteolysis around the vertebrae was observed in any of the involved vertebrae cement or fragmentation of the injected PMMA. CONCLUSIONS: PMMA injected into the vertebral body remains stable over time (more than 15 years). There are no changes in the bone-PMMA interface, osteolysis and/or changes in the height of the vertebral bodies in the cases analyzed

The association between sleep quality, low back pain and disability: A prospective study in routine practice.

BACKGROUND: The objective of this study was to estimate the association between sleep quality (SQ) and improvements in low back pain (LBP) and disability, among patients treated for LBP in routine practice. METHODS: This prospective cohort study included 461 subacute and chronic LBP patients treated in 11 specialized centres, 14 primary care centres and eight physical therapy practices across 12 Spanish regions. LBP, leg pain, disability, catastrophizing, depression and SQ were assessed through validated questionnaires upon recruitment and 3 months later. Logistic regression models were developed to assess: (1) the association between the baseline score for SQ and improvements in LBP and disability at 3 months, and (2) the association between improvement in SQ and improvements in LBP and disability during the follow-up period. RESULTS: Seventy-three per cent of patients were subacute. Median scores at baseline were four points for both pain and disability, as assessed with a visual analog scale and the Roland-Morris Questionnaire, respectively. Regression models showed (OR [95% CI]) that baseline SQ was not associated with improvements in LBP (0.99 [0.94; 1.06]) or in disability (0.99 [0.93; 1.05]), although associations existed between 'improvement in SQ' and 'improvement in LBP' (4.34 [2.21; 8.51]), and 'improvement in SQ' and 'improvement in disability' (4.60 [2.29; 9.27]). CONCLUSIONS: Improvement in SQ is associated with improvements in LBP and in disability at 3-month follow-up, suggesting that they may reflect or be influenced by common factors. However, baseline SQ does not predict improvements in pain or disability. SIGNIFICANCE: In clinical practice, sleep quality, low back pain and disability are associated. However, sleep quality at baseline does not predict improvement in pain and disability.

Potential risks of using cement-augmented screws for spinal fusion in patients with low bone quality.

BACKGROUND CONTEXT: Dramatic increases in the average life expectancy have led to increases in the variety of degenerative changes and deformities observed in the aging spine. The elderly population can present challenges for spine surgeons, not only because of increased comorbidities, but also because of the quality of their bones. Pedicle screws are the implants used most commonly in spinal surgery for fixation, but their efficacy depends directly on bone quality. Although polymethyl methacrylate (PMMA)-augmented screws represent an alternative for patients with osteoporotic vertebrae, their use has raised some concerns because of the possible association between cement leakages (CLs) and other morbidities. PURPOSE: To analyze potential complications related to the use of cement-augmented screws for spinal fusion and to investigate the effectiveness of using these screws in the treatment of patients with low bone quality. STUDY DESIGN: A retrospective single-center study. PATIENT SAMPLE: This study included 313 consecutive patients who underwent spinal fusion using a total of 1,780 cement-augmented screws. METHODS AND OUTCOME MEASURES: We analyzed potential complications related to the use of cement-augmented screws, including CL, vascular injury, infection, screw extraction problems, revision surgery, and instrument failure. There are no financial conflicts of interest to report. RESULTS: A total of 1,043 vertebrae were instrumented. Cement leakage was observed in 650 vertebrae (62.3%). There were no major clinical complications related to CL, but two patients (0.6%) had radicular pain related to CL at the S1 foramina. Of the 13 patients (4.1%) who developed deep infections requiring surgical debridement, two with chronic infections had possible spondylitis that required instrument removal. All patients responded well to antibiotic therapy. Revision surgery was performed in 56 patients (17.9%), most of whom had long construction. A total of 180 screws were removed as a result of revision. There were no problems with screw extraction. CONCLUSIONS: These results demonstrate the efficacy and safety of cement-augmented screws for the treatment of patients with low bone mineral density.

Variante sólida de quiste óseo aneurismático en raquis / Solid aneurysmal bone cyst of the spine

Introducción. Presentamos un caso de la variante sólida del quiste óseo aneurismático en una niña de 6 años de edad. Caso clínico. Los hallazgos de la radiología convencional y de la tomografía computarizada (TC) en este caso son indistinguibles de un proceso maligno. En la resonancia magnética (RM) se observa una masa isointensa homogénea bien delimitada en T1, ocupando el hemicuerpo vertebral izquierdo extendiéndose por el pedículo, proceso transverso y la lámina ipsilateral de la segunda vértebra lumbar. También se visualiza una marcada compresión del canal sin cambios de señal en la médula. Los tejidos blandos perilesionales están intactos y no se observan niveles de fluidos en la masa. Se realiza una biopsia guiada por TC que es filiada como variante sólida del quiste óseo aneurismático. Tratamiento. Se trata a la paciente mediante embolización con catéter de la lesión, seguida de una descomprensión anterior y posterior más fusión posterior (AU)

Tumores de escápula de estirpe cartilaginosa / Scapular tumors of cartilaginous origin

Los tumores primarios de escápula son muy infrecuentes. Se presentan 3 casos de tumores de estirpe condral primarios de este hueso, que representan los diferentes tipos: osteocondroma, condrosarcoma y encondroma. Los 2 primeros son los tumores más frecuentes de la escápula, mientras que el encondroma es excepcional. Habitualmente, estos tumores se manifiestan por dolor de características mecánicas y por la aparición de una tumoración. En esta serie es interesante destacar que en el caso del osteocondroma, el paciente presentaba una deformidad en escápula alada secundaria al efecto masa producido por la tumoración situada en la fosa subescapular. El encondroma se localizaba en la cara inferior del acromion y producía clínica de atrapamiento subacromial al interferir con la función del manguito rotador. Todos los tumores se trataron quirúrgicamente y en la actualidad los pacientes están asintomáticos. (AU)

[Malignant lumbosciatic syndrome. Report of 21 cases with vertebral metastases]. / Síndrome lumbociático maligno. A propósito de veintiún casos de metástasis vertebrales.

We describe twenty one cases of tumoral metastasis on the vertebral column simulating initially discal herniation. All of them presented sciatica as a primary clinical manifestation of the malignant tumor. We describe here the differential diagnosis with other pathologies and the different outcome, like the poor response to regular treatment, alteration of the normal status, and alteration of the laboratory data. The radiologic findings and the laboratory abnormalities found in the emergency analysis should induce us to do more complete studies of the patient aimed to identify an underlying tumoral pathology.
