All patients were routinely followed in the outpatient clinic; radiological and clinical examinations (1, 2, 3, 6 months after surgery and then yearly) were conducted and the following noted: time to union, loss of reduction, hardware failure (loosening or breakage) and local or systemic complications.
Implant fatigue failure (screw bending or breakage) may occur weeks or months after the initial surgery and typically is observed in the strong, dense bone of young trauma patients [ 19].
Over the course of time, battery failure or lead wire breakage may occur, requiring surgery to replace the defective DBS components.
The radiological criteria included absence of implant failure (signs of loosening or breakage), signs of graft incorporation and bone fracture healing, continuity of the trabecular bone through the bone fragments and graft, presence of bone callus, and presence of at least three out of four cortices in the anteroposterior and lateral radiographs [ 13].
However, serious concerns still exist regarding pin migration or breakage, pin-site infection, fixation failure, and recurrent instability after pin removal [14, 21, 31].
In case of failure or inappropriate resolution of UFBs, chromosomal breakage at CFS can occur, and micronuclei containing fragile site DNA can be detected leading to chromosomal instability.
Experienced condom users are significantly less likely to have a condom slip or break compared to first-time users, although users who experience one slippage or breakage are more likely to suffer a second such failure.
The way of knot failure was noted to determine whether certain knot types failed more frequently due to slippage or breakage.
To identify the prevalence and correlates of condom failure (defined as breakage or slipping off in the past 90 days) among a sample of adolescent males (15 to 21 years of age).
In our series, no implant failure as plate breakage or bending occurred.
