ABSTRACT Despite being the second most common cause of road traffic injuries (RTIs) in Nigeria, no study had examined the peculiarities of motorcycle crash site characteristics in Nigeria. We examined and interviewed 363 motorcycle RTI patients in three tertiary hospitals in southwest Nigeria. All the motorcycles are small with capacities between 80 and 125cm3. 68.9% of the patients sustained their injuries while working or going to work and 23.4% on their way to school. 176 (48.5%) of the crashes were with moving vehicles and in 83 (22.3%) cases, either the motorcycle or the other vehicle is moving against the traffic. 37.8% of all crashes occurred at junctions with no roundabout versus 5% at junctions with roundabout. Some risky practices of the patient included carrying more than 2 persons (15.02%), travelling without headlight at night (31.7%) and not wearing helmets (96.5%). This study showed that risky behavior among motorcycle riders, chaotic traffic and road design faults accounted for most of the motorcycle crashes. The implications for the prevention and control of motorcycle injuries were discussed.

    ABSTRACT: Powered-two-wheelers (PTWs) constitute a very vulnerable type of road users. The notable increase in their share in traffic and the high risk of severe accident occurrence raise the need for further research. However, current research on PTW safety is not as extensive as for other road users (passenger cars, etc.). Consequently, the objective of this research is to provide a critical review of research on Power-Two-Wheeler behaviour and safety with regard to data collection, methods of analysis and contributory factors, and discuss the needs for further research. Both macroscopic analyses (accident frequency, accident rates and severity) and microscopic analyses (PTW rider behaviour, interaction with other motorised traffic) are examined and discussed in this paper. The research gaps and the needs for future research are identified, discussed and put in a broad framework. When the interactions between behaviour, accident frequency/rates and severity are co-considered and co-investigated with the various contributory factors (riders, other users, road and traffic environment, vehicles), the accident and injury causes as well as the related solutions are better identified.

    ABSTRACT: BACKGROUND: Management of post trauma tibia bone gap varied with orthopedic surgeons' experience and tools available. Study aims to determine predictive factors for distraction by a monotube fixator (DMF) outcome in post tibia trauma limb length discrepancy. METHODS: A prospective descriptive cross sectional study of post traumatized tibia bone gap and limb length discrepancy patients at tertiary hospitals. Patient's informed consent and institutional ethical committee approval were obtained. Bio-data, clinical and healing indexes were documented. DMF was applied for patient that met inclusion criteria. The Statistic tests used included the Chi-square, the Student's two-tailed t test, and the Wilcox on rank-sum test when appropriate. Mantel-Haenszel Common Odds Ratio (OR) and 95% confidence intervals for poor outcome potential risk factors were recorded. Bivariate correlation and logistic regression were evaluated. Significance level was set at a p value <0.05. RESULTS: Thirty-six patients with mean age, 37.2 +/- 10.3 year and male/female ratio of 1:1.25 had DMF applied. Motorcycle accident accounted for 50.0% of patients and diaphyseal segment was most commonly affected 25 (69.4%). The mean bone lengthened was 10.1 +/- 4.0 cm (range: 5-21 cm) and mean duration of bone transport was 105.6 +/- 38.2 days. The means of rate of distraction, healing index and percentage of lengthening were 0.99 +/- 0.14 mm/day, 15.6 +/- 4.3 days/cm and 38.0 +/- 14.3 respectively. The mean follow up was 9.7 +/-4.9 months (range: 2--17.0). Per operative complications varied and outcome was satisfactory in 30(83.3%). Obesity (p <0.0001), multiple surgery (p = 0.012) and transfusion (p = 0.001) correlated to poor outcome. Percentage lengthening >= 50%, bone gap >10 cm, anemia, blood transfusion, general anesthesia administration, distraction rate >1 mm/day, osteomyelitis and prolong partial weight bearing were significant predictive factors for poor outcome in post traumatic tibia distraction. CONCLUSION: Distraction by a monotube fixator appears effective in achieving correction >38.0% original tibia lengthening following traumatic bone gap. Predictive factors for poor outcome were useful for prognostication.

    ABSTRACT: Motorcyclists are the most crash-prone road-user group in many Asian countries including Singapore; however, factors influencing motorcycle crashes are still not well understood. This study examines the effects of various roadway characteristics, traffic control measures and environmental factors on motorcycle crashes at different location types including expressways and intersections. Using techniques of categorical data analysis, this study has developed a set of log-linear models to investigate multi-vehicle motorcycle crashes in Singapore. Motorcycle crash risks in different circumstances have been calculated after controlling for the exposure estimated by the induced exposure technique. Results show that night-time influence increases crash risks of motorcycles particularly during merging and diverging manoeuvres on expressways, and turning manoeuvres at intersections. Riders appear to exercise more care while riding on wet road surfaces particularly during night. Many hazardous interactions at intersections tend to be related to the failure of drivers to notice a motorcycle as well as to judge correctly the speed/distance of an oncoming motorcycle. Road side conflicts due to stopping/waiting vehicles and interactions with opposing traffic on undivided roads have been found to be as detrimental factors on motorcycle safety along arterial, main and local roads away from intersections. Based on the findings of this study, several targeted countermeasures in the form of legislations, rider training, and safety awareness programmes have been recommended.
