IL RITARDO DI CONSOLIDAZIONE DELLE FRATTURE : FATTORI MECCANICI
No full textFracture nonunion is a dreadful entity and can account for a high
percentage of both surgeon and patient’ s stress and frustration.
Fracture nonunion is often anticipated after a severe traumatic
injury, such as an open fracture with segmental bone loss, but it
may also make an unanticipated appearance after treatment of
a low-energy fracture that seemed destined to heal.
The most basic requirements for fracture healing include both
biological and mechanical factors. Biological factors are distinguished
as local and systemic and are physiological and pathological
condition of bone and of the whole subject. Mechanicalfactors able to determine nonunion are essentially distinguished
in quality of reduction, quality and quantity of fixation, devices
positioning. The introduction of new surgical devices is the evidence
of the understanding of biomechanical issues of bone.
Those precious innovative instruments must be known by the surgeon
in a theoretical mode; only respecting the biomechanical
rules of bone healing and applying those to his surgical practice
he could finally benefit of them and avoid the causes connected
to nonunion events
Should we use ceramic-on-ceramic coupling with large head in total hip arthroplasty done for displaced femoral neck fracture?
No full textIntracapsular femoral neck fractures are very common orthopedic injuries; total hip arthroplasty has been demonstrated to be an optimal option, but one of the major concerns remains
the fact that it may dislocate.The aim of this study is to retrospectively review patients with a
displaced intracapsular femoral neck fracture who underwent total hip arthroplasty to realize
whether the use of large-diameter ceramic-on-ceramic coupling has the potential to substantially reduce the risk of such a complication. Among 690 hip replacements performed in a
period of 8 years,we have selected 86 total hip arthroplasties done for displaced intracapsular
fracture of the femoral neck in 64 women and 22 men with a mean age at operation of 67.9
years. Ceramic-on-ceramic coupling was chosen in 38cases,a 36-mm head was used in 36 cases. At the latest follow-up,there were no cases requiring revision surgery and periprosthetic
osteolysis was undetectable.There were no cases of dislocations.New-generation ceramic-on-
ceramic bearings with heads of large diameter should therefore be considered to address the
problem of dislocation after total hip replacement is done for displaced femoral neck fracture

Hip joint hydatidosis after prosthesis replacement
Full text linkHydatidosis is a rare parasitic disease caused by the Echinococcus tapeworm, which only occasionally affects the musculoskeletal tissues. In this article we describe the case of a patient who underwent a total hip replacement procedure for a pathological fracture of the femur neck. At the next histological examination it was shown to be a consequence of secondary bone hydatidosis. This clinical case is exceptional in that the infection spread to the cotyloid and femoral prosthesis components and, in the following years, caused repeated episodes of joint dislocation
