Background The developing world contains more than of the world's population, and has the largest burden of musculoskeletal disease. Published studies provide crucial information that can influence healthcare policies. Presumably much information regarding burden in the developing world would arise from authors from developing countries. However, the extent of participation of authors from the developing world in widely read orthopaedic journals is unclear.
BackgroundThe purpose of this study was to characterize the orthopedic trauma workload in the Bedford Orthopaedic Centre (BOC), an orthopedic referral hospital in rural South Africa.MethodsDemographic data, injury data, and information about initial management were collected for two 6-week periods during both 2008 and 2009 from patients seen in the BOC outpatient department. Two primary outcomes were evaluated: (1) the interval between the initial outside evaluation and the BOC consultation and (2) the presence of established infection at the time of consultation. Secondary outcomes included assessments of the initial management at the referring facility.ResultsMost patients were adult men. Almost half were referred from within a radius of 10 km, but more than one-third came from facilities in excess of 50 km away. The most frequent mode of transport was ambulance followed by taxi-van. Fractures accounted for most of the injuries. Motor vehicle accidents and assaults were more prevalent among adults than among children, for whom falls accounted for a large proportion of injuries. Referral was delayed more than 72 h in 41.4% of patients. Established infections were indentified in 12.2%. Deficiencies detected during prehospital care were common.ConclusionThe burden of orthopedic trauma in this rural referral center is sufficient to justify the manpower and resources needed for a major orthopedic trauma center. Because most of the injuries were fractures, efforts should be aimed at improving fracture care. Differences in the mode of injury and in the anatomical sites involved between adults and children highlight the need for focused preventive measures. Reducing both delays in referral and deficiencies in initial management might well reduce the cost and complexity of the definitive treatment required.
Purpose This study compares the mechanical properties of low-cost stainless steel dynamic compression plates (DCPs) from developing-world manufacturers, adhering to varying manufacturing quality standards, with those of high-cost DCPs manufactured for use in the developed world. Methods Standard-design ten-hole DCPs from six developing-world manufacturers and high-cost DCPs from two manufacturers in the developed world were studied. Nine plates from each manufacturer underwent mechanical testing: six in four-point monotonic bending to assess strength and stiffness and three in four-point bending fatigue. Statistical comparisons of the group means of monotonic bending test data were made, and a qualitative comparison was performed to assess failures in fatigue. Results Low-cost DCPs from manufacturers with at least one manufacturing quality standard had significantly higher bending strength and fewer failures in fatigue than did those from low-cost manufacturers with no recognised quality standards. High-cost DCPs demonstrated greater bending strength than did those in both low-cost groups. There were no differences in stiffness and fatigue failure between highcost DCPs and those low-cost DCPs with quality standards. However, high-cost DCPs were significantly less stiff and had fewer fatigue failures than low-cost DCPs manufactured without such standards. Conclusion Significant differences were found in the mechanical properties of ten-hole DCP plates from selected manufacturers in the developing and developed worlds. These differences correlated with reported quality certification in the manufacturing process. Mechanical analysis of low-cost implants may provide information useful in determining which manufacturers produce implants with the best potential for benefit relative to cost.
