In a decidedly upper limb themed series of reviews this edition of Cochrane Corner summarises four new and updated reviews published by the Cochrane Bone, Joint and Muscle Trauma Group over the last few months. The tenacious reviewers at the Cochrane collaboration have turned their beady eyes to conservative treatments for shoulder dislocations and clavicle fractures along with evaluation of femoral nerve blocks in knee replacement and how to best manage entrapment injuries in children.

The first Cochrane Corner of 2014 reports on a bumper number of new and updated reviews from the Cochrane Collaboration. Since November the Cochrane collaboration have turned their beady eye to scrutinise several topical (and sometimes controversial) orthopaedic issues such as pin site care, the use of Continuous Passive Motion (CPM) in the rehabilitation of total knee replacement (TKR) and the efficacy of nerve blocks.

While the Cochrane Collaboration have been busy over the last four months, only a handful of their published reviews have been of any relevance to orthopaedic and trauma surgeons. Those that are provide the reader with an overview of work on imaging modalities, antibiotic therapy, changes to the surgical site dressing and practices surrounding post-operative wound management, including post-op bathing and negative pressure wound therapy for use in the treatment of diabetic foot wounds.

Things have not been quiet in the Cochrane Collaboration in the four months since the last 'Cochrane Corner', with the publication of six new or updated reviews summarised here, all conducted with the bulletproof Collaboration's methodology representing the pinnacle of evidence relevant to orthopaedic surgeons.
