Pathological fractures in children: Diagnosis and treatment options
No full textA fracture is defined as pathological when it arises in a bone tissue that has been modified and reshaped by
a local or systemic pathological process. In children, pathological fractures can be secondary to several
conditions, ranging from metabolic diseases to tumors, infections or neuromuscular pathologies. History,
clinical examination and radiologic assessment are essential to making a diagnosis, to identifying
the underlying cause and to planning the right treatment of a pathological fracture. Treatment must be
tailored to both the fracture and the underlying cause. The objective of this work is to present the diagnostic
approach and the course to follow when a child presents with a pathological fracture. The most
common causes of pathological fractures, as well as their characteristics, will be described. Pathological
fractures occurring in osteogenesis imperfecta and in abused children as well as stress fractures will not
be discussed

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Rotationplasty as a salvage of failed primary limb reconstruction: up to date review and case report
No full textWe report a case of a 15-year-old girl who is a known case
for proximal focal femoral deficiency. She underwent
several surgical lengthening procedures. Her course was
complicated by femur nonunion, knee joint dislocation, stiff
knee, and final lower limb discrepancy of over 15 cm.
Rotationplasty was performed to salvage her previous
surgical failures and restore her function. Surgery was
uneventful and the patient was able to walk with the
prosthesis in a few months after index surgery. Although
the outcome of rotationplasty is visually unusual, for some
children restored function and physical capabilities
outweigh cosmetic concerns. The aim of the present study
was to report a case of rotationplasty in salvaging a failed
primary limb reconstruction in a patient with proximal
femur focal deficiency

No full textDevelopment of the spine and thoracic cage consists
of a complex series of events involving multiple metabolic
processes, genes and signaling pathways. During
growth, complex phenomena occur in rapid succession.
This succession of events, this establishment of
elements, is programmed according to a hierarchy.
These events are well synchronized to maintain harmonious
limb, spine and thoracic cage relationships,
as growth in the various body segments does not occur
simultaneously at the same magnitude or rate.
In most severe cases of untreated progressive earlyonset
spinal deformities, respiratory insufficiency and
pulmonary and cardiac hypertension (cor pulmonale ),
which characterize thoracic insufficiency syndrome
(TIS), can develop, sometimes leading to death. TIS is
the inability of the thorax to ensure normal breathing.
This clinical condition can be linked to costo-vertebral
malformations (e.g. , fused ribs, hemivertebrae, congenital
bars), neuromuscular diseases (e.g. , expiratory
congenital hypotonia), Jeune or Jarcho-Levin syndromes
or to 50% to 75% fusion of the thoracic spine
before seven years of age. Complex spinal deformities
alter normal growth plate development, and vertebral
bodies become progressively distorted, perpetuating
the disorder. Therefore, many scoliotic deformities can
become growth plate disorders over time. This review
aims to provide a comprehensive review of how spinal
deformities can affect normal spine and thoracic cage
growth. Previous conceptualizations are integrated
with more recent scientific data to provide a better
understanding of both normal and abnormal spine and
thoracic cage growth.
