Forty-three patients were randomly allocated to undergo either trapeziectomy alone (control) or with a ligament reconstruction and tendon interposition (LRTI) using an abductor pollicis longus tendon slip. The patients were reviewed at a median 13 (range, 7-29) months after surgery. The demographic characteristics, severity of disease and pre-operative clinical measurements of the two study groups were indistinguishable but LRTI lengthened the operation by approximately 15 minutes. Both groups expressed equal satisfaction with the operation and there were no significant differences between the two treatment groups. Simple trapeziectomy is an effective operation for osteoarthrosis at the base of the thumb and the addition of a ligament reconstruction was not shown to confer any additional benefit.

We assessed the influence of the use of a tourniquet in total knee arthroplasty in a prospective, randomised study. After satisfying exclusion criteria, we divided 77 patients into two groups, one to undergo surgery with a tourniquet and one without. Both groups were well matched. The mean change in knee flexion in the group that had surgery without a tourniquet was significantly better at one week (p = 0.03) than in the other group, but movement was similar at six weeks and at four months. There was no significant difference in the surgical time, postoperative pain, need for analgesia, the volume collected in the drains, postoperative swelling, and the incidence of wound complications or of deep-venous thrombosis. We conclude that the use of a tourniquet is safe and that current practice can be continued.

BackgroundScaphoid fractures account for 90% of carpal fractures and occur predominantly in young men. Immediate surgical fixation of this fracture has increased, in spite of insufficient evidence of improved outcomes over non-surgical management. We compared the clinical effectiveness of surgical fixation with cast immobilization and early fixation of those that fail to unite, for ≤2 mm displaced scaphoid waist fractures in adults. MethodsThis pragmatic, multicentre, open-label, parallel-group, two-arm randomised clinical trial included adults who presented to orthopaedic departments of 31 hospitals in England and Wales with a clear, bicortical fracture of the scaphoid waist on radiographs. Participants were randomly assigned to early surgical fixation or below-elbow cast immobilization followed by immediate fixation of confirmed non-union. The primary outcome was the Patient Rated Wrist Evaluation (PRWE) total score at 52 weeks post-randomisation. Registration ISRCTN67901257. FindingsOf 439 randomised patients (mean age 33 years, 363 [83%] men), 408 (93%) were included in the primary analyses. There was no difference in PRWE score at 52 weeks (adjusted mean difference -2•1 points, 95% CI -5•8 to 1•6, p=0•27). There were no differences at 52 weeks for the PRWE pain or function subscales. More participants in the surgery group experienced a surgery-related potentially serious complication than in the cast group (n=31, 14% vs n=3, 1%), but fewer had cast-related complications (n=5, 2% vs n=40, 18%). The number experiencing a medical complication (n=4, 2% vs n=5, 2%) was similar in the two groups." InterpretationAdult patients with ≤2 mm displaced scaphoid waist fracture should have initial cast immobilization and suspected non-unions confirmed and immediately fixed. This will help avoid risks of surgery and mostly limit its use to fixing non-union.
