Background: Fracture of the distal radius is a common clinical problem particularly in elderly white women with osteoporosis, in whom the lifetime risk of this injury has been estimated as 15 per cent.
Objectives: To determine the most appropriate conservative treatment for fractures (such as Colles') of the distal radius in adults.
Search strategy: We searched the Cochrane Musculoskeletal Injuries Group trials register, Medline and reference lists of trials. Date of the most recent search: April 1998.
Selection criteria: Randomised or quasi-randomised clinical trials involving skeletally mature patients with a fracture of the distal radius, which compared commonly applied conservative interventions for fracture fixation. These included the application of an external support (plaster cast or brace) and fracture manipulation.
Data collection and analysis: All trials, judged as fitting the selection criteria by both reviewers, were independently assessed by both reviewers for methodological quality. Data were extracted for anatomical, functional and clinical, including complications, outcomes. The trials were grouped into categories relating to cast position, extent and duration of immobilisation, use of braces, cast material and fracture manipulation. Although quantitative data from some trials are presented, the lack of good quality trials and trial heterogeneity inhibited pooling of results.
Main results: Over 50 randomised trials comparing treatment options for distal radial fractures were identified. Twenty nine trials of these, involving a total of 3199 mainly female and older patients, met the inclusion criteria for this review. Comprehensive details of the individual trials are provided in tabular form, and their results, grouped as indicated above, have been presented in text and analyses tables. The poor quality and heterogeneity in terms of patient characteristics, interventions compared and outcome measurement, of the included trials meant that no meta-analyses were undertaken.
Reviewer's conclusions: There is insufficient evidence from randomised trials to determine which methods of conservative treatment are the most appropriate for the more common types of distal radial fractures in adults. Therefore, at present, practitioners applying conservative management should use an accepted technique with which they are familiar, and which is cost-effective from the perspective of their provider unit. Whilst tempting, any call for further research to clarify the most appropriate conservative treatment for this common fracture must be resisted for now. Instead it is important to reflect on the issues raised in this review, to ascertain patient preferences, prioritise researchable questions and undertake a systematic programme of research after agreeing a core data set for classification of fractures and outcomes.
