The purpose of this study was to analyse clinical results of elderly patients with trochanteric fractures that were treated with use of TARGON(®) PF nail. Overall, 494 patients (113 males) were available for this study. On the basis of Jensen classification, there were 76 cases in type I, 164 cases in type II, 70 in type III, 129 in type IV and 55 in type V. (1) Sliding amount of lag screw in relation to the Jensen classification, (2) sliding amount of lag screw according to the Ikuta's classification that categorises the reduction in lateral view in three, Subtype A, Subtype N and Subtype P, (3) sliding amount of lag screw in correlation between Jensen classification and Ikuta's classification and (4) postoperative complications (9 cases; 1.7%) were assessed. ⋯ In correlation between Jensen classification and Ikuta's classification, the excessive sliding of lag screw was prominent with the Subtype P, which was preoperatively in Jensen type III or V. Cut-out or back-out cases were caused either from (1) Subtype P that were preoperatively Jensen types III or V, or from (2) the fracture where there was bony defect anteriorly. Therefore, special care must be taken for these types.

Factors which impair fracture healing after intramedullary (IM) nailing of long bone fractures range from surgical and biological factors to mechanical parameters. Mechanical parameters known to prolong bony consolidation are share forces at the site of the fracture. Fracture near press-on interlocking reduces share forces directly at the fracture site and is hypothesised to enhance callus mineralisation. A sheep model of midshaft tibia osteotomies evaluates the technique. ⋯ Fracture near press on interlocking increases callus mineralisation in a subcritical osteotomy model in sheep. The results indicate that the reduction of share forces at the fracture site after nailing procedures may be effective in reducing the time until bony consolidation.

The objective of this study is to provide a systematic review on ocular injuries induced by glass bottles containing carbonated drinks in China, which emphasised the injury circumstance and visual function loss. ⋯ One in three ocular injuries from glass bottles containing carbonated drinks show severe vision loss. Relevant workers are most frequently injured, followed by inappropriate handlers or openers. Besides manufacturing standards being strictly implemented, many ocular traumas related to bottled carbonated drinks should be prevented through health education.

Multicenter Study
A strategy to implement and support pre-hospital emergency medical systems in developing, resource-constrained areas of South Africa.
Resource-constrained countries are in extreme need of pre-hospital emergency care systems. However, current popular strategies to provide pre-hospital emergency care are inappropriate for and beyond the means of a resource-constrained country, and so new ones are needed-ones that can both function in an under-developed area's particular context and be done with the area's limited resources. In this study, we used a two-location pilot and consensus approach to develop a strategy to implement and support pre-hospital emergency care in one such developing, resource-constrained area: the Western Cape province of South Africa. ⋯ Management of the system is done through local Community Based Organizations, which can adapt the model to their communities as needed to ensure local appropriateness and feasibility. Within a community, the system is implemented in a graduated manner based on available resources, and is designed to not rely on the whole system being implemented first to provide partial function. The University of Cape Town's Division of Emergency Medicine and the Western Cape's provincial METRO EMS intend to follow this model, along with sharing it with other South African provinces.
