BACKGROUND: Fracture of the distal radius is a common clinical problem, particularly in older white women with osteoporosis. Anaesthesia is usually provided during manipulation of displaced fractures or during surgical treatment. OBJECTIVES: To examine the evidence for the relative effectiveness of the main methods of anaesthesia (haematoma block, intravenous regional anaesthesia (IVRA), regional nerve blocks, sedation and general anaesthesia) as well as associated physical techniques and drug adjuncts used during the management of distal radial fractures in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised register (January 2002), the Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 2001), MEDLINE (1966 to October 2001), EMBASE (1988 to 2001 Week 48), Current Controlled Trials (December 2001) and reference lists of articles. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials evaluating relevant interventions for these injuries (see Objectives). We excluded pharmacological trials comparing drug dosages and, with one exception, different drugs in the same class. Also excluded were trials reporting only pharmacokinetic and/or physiological outcomes. DATA COLLECTION AND ANALYSIS: All trials meeting the selection criteria were independently assessed by the three reviewers for methodological quality. Data were extracted independently by two reviewers. Quantitative data are presented using relative risks or mean differences together with 95 per cent confidence limits. Only very limited pooling of results from comparable trials was possible. MAIN RESULTS: The 18 included studies involved at least 1200, mainly female and older, patients with fractures of the distal radius. All studies had serious methodological limitations, notably in the frequent failure to assess clinically important and longer-term outcomes. Five trials provided evidence that, when compared with haematoma block, IVRA provided better analgesia during fracture manipulation and enabled better and easier reduction of the fracture, with some indication of a reduced risk of later redislocation or need for re-reduction. In contrast, haematoma block was quicker and easier to perform and less resource intensive. There was inadequate evidence of relative effectiveness of different methods of anaesthesia only examined within single trials: nerve block versus haematoma block; intravenous sedation versus haematoma block; general anaesthesia versus haematoma block; general anaesthesia versus sedation; and general anaesthesia versus haematoma block and sedation. None of the three trials evaluating three different physical aspects of anaesthesia (injection site of, or extra tourniquet, for IVRA; and technique for brachial plexus block) provided conclusive evidence for the effectiveness and safety of the novel technique. Six trials examined the use of drug adjuncts. The addition of two different muscle relaxants and one analgesic was tested for IVRA; one sedative and hyaluronidase for haematoma block; and clonidine for brachial plexus block. All trials evaluating adjuncts failed to provide evidence on eventual clinical outcome. A seriously flawed study comparing bupivacaine with prilocaine for IVRA gave some insight on the potential confounding effects of treatment by different doctors on patient outcome. REVIEWER'S CONCLUSIONS: There was insufficient robust evidence from randomised trials to establish the relative effectiveness of different methods of anaesthesia, different associated physical techniques or the use of drug adjuncts in the treatment of distal radial fractures. There is, however, some indication that haematoma block provides poorer analgesia than IVRA, and can compromise reduction. Given the many unresolved questions over the management of these fractures, we suggest an integrated programme of research, which includes consideration of anaesthesia options, is the way forward.
