An analysis was made of 1176 whiplash-type neck distortions taken from a total of 3838 restrained car driver incident reports. The percentage of whiplash-type neck distortion among injured drivers increased from less than 10% in 1985 to over 30% in 1997. Most occurred in head-on crashes or crashes with multiple collisions; only 15% occurred in rear-end collisions. ⋯ A correlation between the severity of the accompanying injuries and duration of complaints was found. Lack of adequate follow-up for patients with less severe injuries posed considerable difficulties for this retrospective study. In order to better evaluate this problem, prospective studies are necessary, with documentation including diagnosis, treatments, complaint duration and type.

A high rate of failure of the internal fixation of unstable spinal fractures in complete cord injured patients was noted in patients referred to the Salisbury Spinal Centre who had been stabilised with a Hartshill rectangle. This prompted a review of the operative notes, radiographs and clinical outcomes of all patients referred to the centre with a Hartshill rectangle in situ. All patients identified with a complete spinal cord injury and Hartshill rectangle were identified. ⋯ The failure to use bone graft at the time of stabilisation was significantly (P < 0.001) related to risk of failure. The application and use of the Hartshill is not a technically challenging procedure; however, if the system is to be used, it must be used correctly. Failure to correctly apply the rectangle and to use bone graft will lead to an unacceptably high rate of failure.

Postoperative pancreatitis may occur following surgery in regions remote from the pancreas and the biliary tree. Though uncommon, it carries a high mortality rate. Pancreatitis complicating spinal surgery is extremely rare. This report describes a case of acute pancreatitis following an anterior lumbar interbody fusion and discusses the possible mechanisms of pancreatic cellular injury.

Comparative Study
Titanium-alloy enhances bone-pedicle screw fixation: mechanical and histomorphometrical results of titanium-alloy versus stainless steel.
Several types of pedicle screw systems have been utilized to augment lumbar spine fusion. The majority of these systems are made of stainless steel (Ss), but titanium-alloy (Ti-alloy) devices have recently been available on the market. Ti-alloy implants have several potential advantages over Ss ones. ⋯ Bone ongrowth on Ti was increased by 33% compared with Ss (P < 0.04), whereas no differences in bone volume around the screws were shown. Mechanical binding at the bone-screw interface was significantly greater for Ti pedicle screws than for Ss, which was explained by the fact that Ti screws had a superior bone ongrowth. There was no correlation between the screw removal torque and the pull-out strength, which indicates that the peripheral bone structure around the screw was unaffected by the choice of metal.

Clinical Trial Controlled Clinical Trial
Outcome scores in degenerative cervical disc surgery.
Forty-six consecutive patients with neck pain and arm radiculopathy were treated with anterior cervical discectomy and fusion. All patients had neurological symptoms corresponding to a herniated disc and/or spondylosis at one or two cervical levels, verified by magnetic resonance imaging. The patients were stabilized with an anterior graft and randomized to either fixation with a CSLP plate or no internal fixation. ⋯ We conclude that the modified Million Index and Oswestry Index are clinically useful tools in the evaluation of outcome after degenerative cervical disc surgery. The clinical benefits of plate fixation were minimal. The outcome after surgery, measured with the Oswestry Index, Million Index and VAS for arm and neck pain, seems to correlate well with the classification of outcome by Odom.
