Bicycle injuries in children.

An analysis of 405 bicycle accidents in children under 15 years of age resulting in their attendance at hospital has shown that those having accidents while riding modern "high-rise" bicycles suffered head injury and bone fracture and required hospital admission more frequently than did those riding conventional models. "High-rise" accidents tended to occur on newly acquired and borrowed machines, suggesting that lack of experience of the handling properties of these bicycles may be a factor in the causation of accidents.

Head injuries in children.

Two-hundred children with head injury admitted consecutively to paediatric wards in the two main hospitals in Newcastle upon Tyne have been studied. Eight children required neurosurgical operation. There were two deaths. Details of the cause and consequences of the accidents have been analysed and an attempt has been made to identify psychological or physical factors that may predispose to injury. There was a slightly higher proportion of children with what are regarded as adverse personality factors among the head injuries than in a control group and there were more left-handed children than would be expected in the general population. The results suggest that the modern "high-rise" bicycle may carry a special risk of head injury.

Effect of joint position and ligament tension on the MR signal intensity of the cruciate ligaments of the knee.

Six cadaveric lower extremities were imaged with T1-weighted spin-echo pulse sequences with the knees extended and flexed to 90 degrees. Magnetic resonance signal intensities of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) were compared. Changing from extension to flexion resulted in decreased signal intensity in six of six ACLs and five of six PCLs. Two of the knees were then imaged with and without tension applied to the ACL. Both specimens showed a decrease in signal intensity with tension, followed by an increase in signal intensity with release of the tension. Finally, in three of the limbs the ACL was surgically reconstructed and then imaged with and without tension applied to the tendon graft. Signal intensity decreased with tension and increased with release of the tension in all three specimens. Thus, joint position and changes in ligament tension affect the signal intensity of the ACL and PCL, generally resulting in a signal intensity decrease with tension.
