The aim of the present study was to comparatively analyse certain outcome measures of open tibial fractures, stratified per grade of open injury and method of treatment. For this purpose, a systematic review of the English literature from 1990 until 2010 was undertaken, comprising 32 eligible articles reporting on 3060 open tibial fractures. Outcome measures included rates of union progress (early union, delayed union, late union and non-union rates) and certain complication rates (deep infection, compartment syndrome and amputation rates). ⋯ However, lower deep infection rates for IIIA open fractures treated with RTNs were recorded compared with grades I and II. Interestingly, grade II open tibial fractures, treated with UTN, presented significantly greater odds for developing compartment syndrome than when treated with RTNs. Our cumulative analysis, providing for each grade of open injury and each particular method of treatment a summarised estimate of effect size for the most important outcome measures of open tibial fractures, constitutes a useful tool of the practicing surgeon for optimal decision making when operative treatment of such fractures is contemplated.

Review Meta Analysis
Outcomes in lower limb amputation following trauma: a systematic review and meta-analysis.
Lower limb amputation (LLA) is life-changing surgery. Shorter residual limbs are known to place greater physiological strain on patients than longer residual limbs; however, there is ongoing debate as to whether through-knee amputations are preferable to above-knee amputations. This analysis aims to resolve this question by systematically collecting and pooling published and unpublished data on this subject. ⋯ This study describes the impact of LLA of different levels on patients' lives. The results indicate that patients with a TKA have a better physical quality of life than those with an AKA and, therefore, support the surgical strategy of maintaining maximum length and performing TKA in preference to AKA, where possible.

We review prevention strategies to minimise the risk of MRSA soft tissue and bone infections, which can be devastating for the patient and costly for the healthcare provider. Department of Health (England) policy is that screening for emergency admissions will be mandatory from 2011, in addition to existent elective admission screening. Rapid screening technology has not been shown to be cost-effective, meaning that there will be a lag time between admission and the patient's MRSA status being known. ⋯ Prevention of orthopaedic infections clearly involves general operating theatre protocols, such as suitable antiseptic skin preparation, and additional measures including the use of laminar airflow. Antibiotic prophylaxis is adjusted in patients known to have MRSA to include a glycopeptide, and local guidelines may adopt such regimens for all patients due to the burden of MRSA in the local patient population. A future development that may have an effect on practice is the development of a Staphylococcus aureus vaccine, which has been shown to be cost-effective in a computer-modelled evaluation.

Review
What is the effect of compartment syndrome and fasciotomies on fracture healing in tibial fractures?
Acute compartment syndrome (ACS) in tibial diaphyseal fractures has been associated with such complications as infection, delayed fracture healing or non-union, sensory and motor deficits, deformities, and poor functional outcome. Essential condition of an uncomplicated recovery is early diagnosis with prompt decompression. ⋯ There were statistically significant differences in the time to healing, being longer by 4.90 weeks (p<0.001), and in the rates of delayed union or non-union (55% versus 17.8%) (p<0.001) when these fractures were compared to tibial fractures without compartment syndrome. Patients with ACS of the tibia undergoing leg fasciotomies should be informed about the increased risk of impaired fracture healing and longer time to union.

MRSA is becoming increasingly common worldwide. With the emergence of new highly spreadable strains (community associated or CA-MRSA) novel presentation skin and soft tissue infections (SSTI) are being seen. ⋯ Empirical antimicrobial management choices can be difficult, but clues to the nature of the MRSA may be gleaned from the history and clinical presentation. More severe SSTI due to necrotising fasciitis and purpura fulminans are emerging and warrant the broadest possible empirical Gram-positive cover, ideally with antimicrobials that stop exotoxin production, and sometimes intravenous immunoglobulin to neutralise exotoxins already produced.
