@article { , title = {Surgery versus cast immobilisation for adults with a bicortical fracture of the scaphoid waist (SWIFFT): a pragmatic, multicentre, open-label, randomised superiority trial}, abstract = {Background Scaphoid fractures account for 90\% of carpal fractures and occur predominantly in young men. The use of immediate surgical fixation to manage this type of fracture has increased, despite insufficient evidence of improved outcomes over non-surgical management. The SWIFFT trial compared the clinical effectiveness of surgical fixation with cast immobilisation and early fixation of fractures that fail to unite in adults with scaphoid waist fractures displaced by 2 mm or less. Methods This pragmatic, parallel-group, multicentre, open-label, two-arm, randomised superiority trial included adults (aged 16 years or older) who presented to orthopaedic departments of 31 hospitals in England and Wales with a clear bicortical fracture of the scaphoid waist on radiographs. An independent remote randomisation service used a computer-generated allocation sequence with randomly varying block sizes to randomly assign participants (1:1) to receive either early surgical fixation (surgery group) or below-elbow cast immobilisation followed by immediate fixation if non-union of the fracture was confirmed (cast immobilisation group). Randomisation was stratified by whether or not there was displacement of either a step or a gap of 1–2 mm inclusive on any radiographic view. The primary outcome was the total patient-rated wrist evaluation (PRWE) score at 52 weeks after randomisation, and it was analysed on an available case intention-to-treat basis. This trial is registered with the ISRCTN registry, ISRCTN67901257, and is no longer recruiting, but long-term follow-up is ongoing. Findings Between July 23, 2013, and July 26, 2016, 439 (42\%) of 1047 assessed patients (mean age 33 years; 363 [83\%] men) were randomly assigned to the surgery group (n=219) or to the cast immobilisation group (n=220). Of these, 408 (93\%) participants were included in the primary analysis (203 participants in the surgery group and 205 participants in the cast immobilisation group). 16 participants in the surgery group and 15 participants in the cast immobilisation group were excluded because of either withdrawal, no response, or no follow-up data at 6, 12, 26, or 52 weeks. There was no significant difference in mean PRWE scores at 52 weeks between the surgery group (adjusted mean 11·9 [95\% CI 9·2–14·5]) and the cast immobilisation group (14·0 [11·3 to 16·6]; adjusted mean difference −2·1 [95\% CI −5·8 to 1·6], p=0·27). More participants in the surgery group (31 [14\%] of 219 participants) had a potentially serious complication from surgery than in the cast immobilisation group (three [1\%] of 220 participants), but fewer participants in the surgery group (five [2\%]) had cast-related complications than in the cast immobilisation group (40 [18\%]). The number of participants who had a medical complication was similar between the two groups (four [2\%] in the surgery group and five [2\%] in the cast immobilisation group). Interpretation Adult patients with scaphoid waist fractures displaced by 2 mm or less should have initial cast immobilisation, and any suspected non-unions should be confirmed and immediately fixed with surgery. This treatment strategy will help to avoid the risks of surgery and mostly limit the use of surgery to fixing fractures that fail to unite.}, doi = {10.1016/S0140-6736(20)30931-4}, eissn = {1474-547X}, issn = {0140-6736}, issue = {10248}, journal = {The Lancet}, pages = {390-401}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/3508796}, volume = {396}, keyword = {Health and Health Inequalities, Scaphoid fracture, Screw fixation, Plaster cast, Union, Randomised controlled trial}, year = {2020}, author = {Dias, Joseph and Brealey, Stephen and Fairhurst, Caroline and Amirfeyz, Rouin and Bhowal, Bhaskar and Blewitt, Neil and Brewster, Mark and Brown, Daniel and Choudhary, Surabhi and Coapes, Christopher and Cook, Liz and Costa, Matthew and Davis, Timothy and DisMascio, Livio and Giddins, Grey and Hedley, Helen and Hewitt, Catherine and Hinde, Sebastian and Hobby, Jonathan and Hodgson, Stephen and Jefferson, Laura and Jeyapalan, Kanagaratnam and Johnston, Phillip and Jones, Jonathon and Keding, Ada and Leighton, Paul and Logan, Andrew and Mason, Will and McAndrew, Andrew and McNab, Ian and Muir, Lindsay and Nicholl, James and Northgraves, Matthew and Palmer, Jared and Poulter, Rob and Rahimtoola, Zulfi and Rangan, Amar and Richards, Simon and Richardson, Gerry and Stuart, Paul and Taub, Nicholas and Tavakkolizadeh, Adel and Tew, Garry and Thompson, John and Torgerson, David and Warwick, David} }
