We examined differences in the rate of open reduction, operating time,
To identify a suite of the key physical, emotional, and social outcomes to be employed in clinical practice and research concerning Perthes' disease in children. The study follows the guidelines of the COMET-Initiative (Core Outcome Measures in Effectiveness Trials). A systematic review of the literature was performed to identify a list of outcomes reported in previous studies, which was supplemented by a qualitative study exploring the experiences of families affected by Perthes’ disease. Collectively, these outcomes formed the basis of a Delphi survey (two rounds), where 18 patients with Perthes’ disease, 46 parents, and 36 orthopaedic surgeons rated each outcome for importance. The International Perthes Study Group (IPSG) (Dallas, Texas, USA (October 2018)) discussed outcomes that failed to reach any consensus (either ‘in’ or ‘out’) before a final consensus meeting with representatives of surgeons, patients, and parents.Aims
Methods
The management of children’s fractures has evolved
as a result of better health education, changes in lifestyle, improved
implant technology and the changing expectations of society. This
review focuses on the changes seen in paediatric fractures, including
epidemiology, the increasing problems of obesity, the mechanisms
of injury, non-accidental injuries and litigation. We also examine
the changes in the management of fractures at three specific sites:
the supracondylar humerus, femoral shaft and forearm. There has
been an increasing trend towards surgical stabilisation of these
fractures. The reasons for this are multifactorial, including societal
expectations of a perfect result and reduced hospital stay. Reduced hospital
stay is beneficial to the social, educational and psychological
needs of the child and beneficial to society as a whole, due to
reduced costs. Cite this article:
End caps are intended to prevent nail migration
(push-out) in elastic stable intramedullary nailing. The aim of
this study was to investigate the force at failure with and without
end caps, and whether different insertion angles of nails and end caps
would alter that force at failure. Simulated oblique fractures of the diaphysis were created in
15 artificial paediatric femurs. Titanium Elastic Nails with end
caps were inserted at angles of 45°, 55° and 65° in five specimens
for each angle to create three study groups. Biomechanical testing
was performed with axial compression until failure. An identical
fracture was created in four small adult cadaveric femurs harvested
from two donors (both female, aged 81 and 85 years, height 149 cm and
156 cm, respectively). All femurs were tested without and subsequently
with end caps inserted at 45°. In the artificial femurs, maximum force was not significantly
different between the three groups (p = 0.613). Push-out force was
significantly higher in the cadaveric specimens with the use of
end caps by an up to sixfold load increase (830 N, standard deviation
(SD) 280 These results indicate that the nail and end cap insertion angle
can be varied within 20° without altering construct stability and
that the risk of elastic stable intramedullary nailing push–out
can be effectively reduced by the use of end caps. Cite this article:
