Locking plates for corrective osteotomy of malunited dorsally tilted distal radial fractures: a biomechanical study.
2005
The purpose of the study was to compare the biomechanical properties of five different palmar fixation plate designs in a distal radius osteotomy cadaver model. A 1 cm metaphyseal osteotomy gap was made to simulate a corrective osteotomy and the osteotomy plated. Axial load was applied to the distal end of each construct by a material testing machine under control of a motion analysis video system. The specimens were arranged into five implant groups of eight specimens each. No test group developed deformity and movement of the fracture gap greater than 2 mm with a load of 100 N. Increasing the load to 250 N revealed statistically significant differences in stiffness and failure load betwe…
Stability and surgical complications of tooth-borne and bone-borne appliances in surgical assisted rapid maxillary expansion: a systematic review
2021
The objective of this systematic review was to evaluate the stability and complications of tooth-borne (TB), bone-borne (BB) and hybrid (TB-BB) appliances in surgically assisted rapid maxillary expansion (SARME). Database searches were conducted (PubMed, Embase, Cochrane Library and SciELO), as well as a grey literature search (Google Scholar) and hand searches of reference lists. Forty-six articles were included after study selection (κ=0.854). After eligibility assessment, 16 articles and one article from the grey literature were processed (κ=0.866) and six articles were selected by hand searching, for a total of 23 articles included. Regarding stability, TB appliances showed width relaps…
Biomechanical Diagnosis and Rehabilitation Control of Pes Equinus Patiens by Computerized Motion Analysis
1985
If a foot is fixed in plantar flexion such as to inhibit a dorsal flexion beyond a rectangular position with reference to the lower leg the resulting syndrome is called pes equinus. These patients exhibit a characteristic gait with stance phases on tiptoe that may amount to a severe handicap for them. The pes equinus is a most common deformity found in patients with a hemiplegic or diplegic disorder in the region of the foot and the lower leg with typical structural changes in the ankle joint and the calf muscles. The therapy of the pes equinus depends on its etiology and its severity. A less severe pes equinus deformity can be treated by physical therapy and other conservative measures. Mo…
Hallux Valgus Correction in Young Patients with Minimally Invasive Technique
2012
The term hallux valgus was introduced into the literature in 1871 when Hueter (Hueter, 1871, as cited in Kelikian, 1965) defined the deformity as an abduction contracture in which the great toe is turned away from the mid-line of the body(fig. 1). The adjective valgus implies a static deformity and should not be used interchangeably with abductus which refers to movement caused by muscle function.
Chronic idiopathic hyperphosphatasia with unusual dental findings: a case report
2012
Chronic idiopathic hyperphosphatasia(CIH) or juvenile Paget disease is believed to be a distinct disease characterized by an increase in the serum alkaline phosphatase, cortical thickening and bowing of the long bones, especially the femora. It is a rare autosomal recessive bone disorder, with excessive bone resorption and bone formation. Skeletal malformations in the legs may cause problems in walking and may eventually result in short stature. The radiographic appearances include widening of the diaphyses, vertebral osteoporosis, acetabular protrusion, and thickening of the skull vault. Intensive bisphosphonate treatment prevented the development of deformity and disability but there is n…
Epigenetics in spine curvature disorders
2022
Abstract Scoliosis is a three-dimensional (3D) structural deformity of the spine with a radiological lateral Cobb angle of ≥ 10°. Several classification systems exist, dividing different types regarding the age of onset or the type of etiology. The minority of cases are secondary to congenital, syndromic of neuromosucular diseases. Most of the cases are classified “idiopathic” due to unknown etiology. These were formally divided by the age of onset into “Infantile Idiopathic Scoliosis” (0–3 years), “Juvenile Idiopathic Scoliosis” (JIS—4–10 years), and “Adolescent Idiopathic Scoliosis” (AIS → 10 years). Since the initiative of the Scoliosis Research Society in 2014 all kind of scoliosis with…
Deformidad tipo Checkrein del Hállux y dedos menores del pie sin fractura previa asociada.
2020
espanolPresentamos una revision bibliografica y la descripcion de la tecnica quirurgica en la deformidad tipo Checkrein del hallux y dedos menores del pie. Esta deformidad dinamica provoca a los pacientes una dificultad significativa para caminar y les impide practicar cualquier deporte ya que en la fase de apoyo de la marcha los dedos del pie se ven forzados a una flexion plantar maxima y terminan atrapados debajo del pie. En los casos en que no se asocia a fractura osea la sospecha clinica causante de la lesion es un sindrome compartimental subclinico. El tratamiento descrito en este trabajo consiste en una plastia en Z y la aplicacion de una sutura pulvertaft en el flexor largo del hallu…
Severe beak deformity in Melopsittacus undulatus caused by Knemidocoptes pilae
2014
An outbreak of knemidocoptic mange caused by Knemidocoptes pilae is described in caged Australian budgerigars (Melopsittacus undulatus) in a public park in L´Eliana (Valencia, Spain). Five individuals (5 out of 70) displayed severe malformation of the beak, with the rhamphotheca, rhinotheca, and gnathotheca affected and a slight lateral deviation of the jawbone, which did not, however, impede feeding or grooming.
Material and Technology: Back to the Future for the Choice of Interface for Non-Invasive Ventilation – A Concise Review
2020
Non-invasive ventilation (NIV) has dramatically changed the treatment of both acute and chronic respiratory failure in the last 2 decades. The success of NIV is correlated to the application of the “best ingredients” of a patient’s “tailored recipe,” including the appropriate choice of the selected candidate, the ventilator setting, the interface, the expertise of the team, and the education of the caregiver. The choice of the interface is crucial for the success of NIV. Type (oral, nasal, nasal pillows, oronasal, hybrid mask, helmet), size, design, material and headgears may affect the patient’s comfort with respect to many aspects, such as air leaks, claustrophobia, skin erythema, eye irr…
Posterior subtalar dislocation.
2009
A subtalar dislocation of the foot is an uncommon injury, and cases of posterior subtalar dislocation are even rarer. This injury is characterized by a simultaneous dislocation of talocalcaneal and talonavicular joints while tibiotalar and calcaneocuboid articulations remain intact. Subtalar dislocation is commonly accompanied by fractures of the malleoli, talus, or fifth metatarsal and by a rotational component of the subtalar joint. Subtalar dislocation can occur in any direction and produces significant deformity. This article presents a case of pure posterior subtalar dislocation in an 80-year-old man who presented with pain and deformity in his left ankle following a motorcycle acciden…
