Tratamiento quirúrgico de las lesiones del ligamento colateral cubital con un anclaje intraóseo
2004
Presentamos nuestra experiencia con el empleo de anclajes intraóseos en el tratamiento de las roturas completas del Ligamento Colateral Cubital (LCC). Se intervinieron a 8 pacientes. En todos los casos se trató de lesiones agudas. El tiempo medio de seguimiento fue de 14 meses. La pérdida media de flexión en la articulación MCF fue de 8,1º. En todos los casos, la estabilidad articular al forzar un valgo fue buena. Ningún paciente refirió inestabilidad. Pensamos que el empleo de sutura con anclaje intraóseo es un tratamiento adecuado para las roturas completas del LCC. We present our experience with the suture anchor in the treatment of complete ruptures of ulnar collateral ligament. We oper…
Anatomía descriptiva y funcional del ligamento cruzado anterior: implicaciones clínico-quirúrgicas
1992
El ligamento cruzado anterior (LCA) es una estructura anatómica vital para la estabilidad de la rodilla y su correcta plastias exige que su tensión, dirección y punto ble al LCA original. Este trabajo intenta actualizar los aspectos anatómicos y funcionales fundamentales para una correcta cirugía de las lesiones del LCA. The anterior cruciate ligament (ACL) is a vital structure for stability of the knee and its correct biomechanics. ACL repair by means of grafts requires that tension, direction and attachment points resemble those of original ligament. This work attempts to update the fundamental functional and anatomical aspects for correct surgery of ACL.
Does Function Determine the Structure? Changes in Flexor Hallucis Longus Muscle and the Associated Performance Related to Dance Modality: A Cross-Sec…
2020
Background and Objectives: Flexor hallucis longus pathology is one of the most common conditions of the ankle and foot in dancers, due to the high demand of dance movements performed in an extreme plantar flexion and dorsiflexion range of motion. The objectives of this study were to determine the bilateral differences between the thickness and cross-sectional area of the flexor hallucis longus muscle in dancers, to establish possible differences between dance modalities, and to analyze whether there is a correlation between ultrasonographic parameters or performance variables and the dance modality. Material and Methods: A sample of 50 (29 classical and 21 contemporary) full-time pre-profes…

Glial expression of Swiss cheese (SWS), the Drosophila orthologue of neuropathy target esterase (NTE), is required for neuronal ensheathment and func…
2016
ABSTRACT Mutations in Drosophila Swiss cheese (SWS) or its vertebrate orthologue neuropathy target esterase (NTE), respectively, cause progressive neuronal degeneration in Drosophila and mice and a complex syndrome in humans that includes mental retardation, spastic paraplegia and blindness. SWS and NTE are widely expressed in neurons but can also be found in glia; however, their function in glia has, until now, remained unknown. We have used a knockdown approach to specifically address SWS function in glia and to probe for resulting neuronal dysfunctions. This revealed that loss of SWS in pseudocartridge glia causes the formation of multi-layered glial whorls in the lamina cortex, the firs…
Chimeric Free Vascularized Metatarsophalangeal Joint With Toe Fillet Flap: A Technique for Reconstruction of the Posttraumatic Metacarpophalangeal Jo…
2018
For painful, dysfunctional, posttraumatic metacarpophalangeal (MCP) joints, the free vascularized toe joint transfer may represent a good solution. Successful reconstruction is potentially limited, however, by 2 features of the traditional vascularized metatarsophalangeal (MTP) transfer: inadequate arc of flexion and insufficient soft tissue coverage. The solution to both of these dilemmas lies in the manner of utilizing the donor site. Because of its innate hyperextensibility, rotating the MTP 180° volar to dorsal provides the greatest arc of flexion in the reconstructed MCP. Excellent soft tissue coverage can be provided by elevating the skin paddle of the transferred second toe as a chim…
Evidence for an involvement of NMDA and non-NMDA receptors in synaptic excitation of phrenic motoneurons in the rabbit
1991
Abstract The action of endogenous excitatory amino acids on phrenic motoneurons was studied in anesthetized, vagotomized, paralyzed and artificially ventilated rabbits. The NMDA receptor antagonists APV and ketamine, as well as the non-NMDA receptor antagonists GAMS and DNQX were administered by microinjection into the ventral horn of the spinal segments C3-C5. Injection of each antagonist resulted in a reversible reduction of the phrenic nerve activity. Results suggest an important function of endogenous excitatory amino acids in the excitation of phrenic motneurons. NMDA as well as non-NMDA receptors are involved. The functional role of both receptor types in bulbospinal neurotransmission…
145 Multifunction Role of Osteonectin/SPARC during Human embryonic and Feta Development
1991
The temporal and spatial distribution of osteonectin/SPARC was investigated during different stages of human development by in situ hybridization and histochemistry Specific mRNA was associated with(a) tissues exhibiting high rates of matrix production (skin, vessels, tendons fetal mesenchyme), (b) cells involved in the process of mineralization (osteoblasts, chondrocytes, odontoblasts), (c)production of basement membranes (glomeruli and (d) steroid synthesis (adrenal gland, Leydig cells) In the growth plate, expression was found in the upper hypertrophic and proliferative but not in the mineralized zone. Histochemistry detected osteonectin extra-cellularly in mineralized tissues, whereas o…
Familial mixed congenital myopathy with rigid spine phenotype
1997
We describe a father and daughter with a rigid spine syndrome and proximal myopathy. The index patient was a 42-year-old man, who died from respiratory failure after a lifelong, slowly progressive proximal myopathy and a rigid spine phenotype. This was morphologically characterized by cytoplasmic bodies, increased desmin, features of reducing-body myopathy, and sarcoplasmic and intranuclear tubulofilamentous inclusions. These cases are characterized by an early onset and possibly autosomal-dominant inheritance, with associated complex structural hallmarks of both desmin-related and inclusion body myopathies. Together they may be defined as a complex mixed congenital myopathy with a rigid sp…
Economic evaluations of ergonomic interventions preventing work-related musculoskeletal disorders: a systematic review of organizational-level interv…
2017
Background Work-related musculoskeletal disorders (WMSD) represent a major public health problem and economic burden to employers, workers and health insurance systems. This systematic review had two objectives: (1) to analyze the cost-benefit results of organizational-level ergonomic workplace-based interventions aimed at preventing WMSD, (2) to explore factors related to the implementation process of these interventions (obstacles and facilitating factors) in order to identify whether economic results may be due to a successful or unsuccessful implementation. Methods Systematic review. Studies were searched in eight electronic databases and in reference lists of included studies. Companio…
