RESUMEN

INTRODUCTION: By December 2008, 90% of referrals requiring hospital admission will need to be seen and treated within the 18-week patient pathway. Previously, patients within our trust with suspected carpal tunnel syndrome had to wait 3 months to see a specialist in clinic and, once assessed, would have to wait up to a further 6 months for an open carpal tunnel decompression under local anaesthetic (OCTD/LA). We set up a one-stop clinic, where patients would have their out-patient consultation and surgery on the same day. We evaluated the clinic in order to assess whether it led to reduced waiting times whilst maintaining good clinical outcome and patient satisfaction. PATIENTS AND METHODS: Patients were selected on the basis of the standard referral letter alone. Those selected were then assessed by a single surgeon in the clinic. The patients deemed appropriate underwent an OCTD/LA and were discharged the same day. Patients were followed up with a patient satisfaction and Boston questionnaire. RESULTS: Forty-six patients underwent 63 OCTD/LA, waiting an average of 2.2 months (9 weeks) from referral. There was high patient satisfaction and improvement in symptoms following treatment in the clinic. CONCLUSIONS: We believe a one-stop carpal tunnel clinic can be an efficient and cost-effective way of treating this common condition.

RESUMEN

Fracture of the scaphoid bone is the most common fracture of the carpus, and frequently, diagnosis is delayed. The unique anatomy and blood supply of the scaphoid itself predisposes to delayed union or nonunion. The Synthes scaphoid screw is a cannulated headed screw, which provides superior compression compared with some other devices used to internally fix scaphoid nonunions. Our aim was to conduct a retrospective study looking at the union rate, time to union, and complications and correlating the outcome of treatment against the delay between injury and surgery and location of the fracture within the bone. This study is a review of a cohort of 30 patients treated with a cannulated Synthes scaphoid screw and corticocancellous bone grafting for scaphoid waist delayed union and nonunion at our center. We achieved 86% overall union rate. The patients with delayed union achieved a 100% union rate. Three out of four patients with persistent nonunion after surgery reported no pain and improved function. The failure rate was 75% in patients who had sustained their fracture more than 5 years previously. Our study demonstrates that delayed union of scaphoid waist fractures and scaphoid waist nonunions present for less than 5 years can be successfully treated by fracture compression and bone grafting.

RESUMEN

Thirteen patients with basal joint arthritis of the thumb were treated by simple trapeziectomy. All patients underwent radiological assessment pre-operatively and at 2, 4 and 12 weeks after surgery. Special standardised views were taken to assess changes in the 'trapezial gap'. Collapse of this was noticed up to 4 weeks following surgery but no significant change occurred thereafter. In respect of this collapse, prolonging immobilisation after 4 weeks is probably unnecessary.

RESUMEN

PURPOSE: To compare 2 methods of wound closure-metallic staples or 3-0 undyed vicryl-according to postoperative wound complication rates. METHODS: Patients who underwent surgery for proximal femoral fractures were randomised to have wound closure with metallic staples or with subcuticular vicryl suture. Wounds were regularly examined postoperatively and only those with positive wound swabs were regarded as wound infections. RESULTS: Five infections and one superficial wound dehiscence occurred in the patients who had wound closure with metallic staples. The complication rate was significantly higher for this group compared with the group who had wound closure with subcuticular vicryl suture (p<0.025). CONCLUSION: Superficial wound complication rates are higher for wounds closed with metallic staples compared to wounds closed with subcuticular vicryl.

RESUMEN

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.

RESUMEN

One method of Herbert screw insertion is to mobilize the scaphotrapezial joint and insert the screw through the articular surface of the distal scaphoid. Because of concern that this might predispose to osteoarthritis in the scaphotrapezial joint, we have investigated joint space width and the presence of osteophytes adjacent to the scaphotrapezial joint using high definition macroradiography.Twenty-eight patients with symptomatic primary osteoarthritis of their hands, 23 with a scaphoid fracture successfully treated conservatively and 18 treated with a Herbert screw were studied. The patients with primary osteoarthritis of their hands had more narrowing of the scaphotrapezial joint compared with the other two groups, but patients treated with a Herbert screw had a significantly higher incidence of osteophytosis on the distal scaphoid than the other two groups. With Herbert screw fixation, osteophytosis on the distal scaphoid may cause impingement and pain, and be a predictor of further degenerative joint changes.

RESUMEN

Twenty-eight unstable total hip arthroplasties were treated with an acetabular augmentation wedge. Of the hips, 23 have had no further dislocations at a mean follow-up of 26 months. Five patients continued to dislocate and have needed further surgery. To our knowledge this is the largest reported series of acetabular augmentation with as good results as those of the most successful reported series of this technique, and a success rate comparable to other methods of treating recurrent dislocation. Careful patient selection, and using a thin augmentation wedge to avoid impingement, are important to the success of a technique which is a useful option in the management of recurrent dislocation.

RESUMEN

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.

RESUMEN

We report a case of anterior compartment syndrome in the ipsilateral leg after a revision total hip arthroplasty. Possible causes include post-ischaemic swelling after occlusion of the vessels during prolonged surgery and vigorous repetitive stretching of the muscles of the anterior compartment from the intraoperative use of electrical calf stimulators. Epidural infusions for postoperative analgesia may mask symptoms, but when there is clinical suspicion, we recommend measurement of the compartment pressures and early fasciotomy.

RESUMEN

PURPOSE: A consistent stereoscopic (stereo) effect in disc photographs is important to be certain that apparent depth changes are real and are not the result of artifact caused by a variable stereo angle. The purpose of this study is to compare the accuracy of relative depth assessments using three different stereo photo viewing methods. METHODS: We evaluated the ability of 12 observers to arrange sets of simultaneous stereo photographs (Nidek 3-Dx split-frame slides, Lentec transparencies) and sequential stereo photographs (Zeiss full-frame slides) according to apparent cup depth. Observer arrangements of each set of 10 photographs were compared to a "reference standard" sequence determined from cup depth measurements made by the Imagenet optic nerve analyzer. RESULTS: The median number of sequence errors (n = 6) made by all examiners in arranging the Nidek 3-Dx simultaneous stereo slides was significantly lower than the median number of errors (n = 12) with the Zeiss sequential stereo slides. CONCLUSIONS: Simultaneous stereo slides provide significantly more interobserver consistency for judgements of cup depth than sequential stereo slides.

RESUMEN

Stereoscopic macroradiography was used to study the pattern of union of scaphoid fractures. Of 21 patients who had partial union of a scaphoid fracture, 13 united on the ulnar side and five on the radial side only. In three it was on both sides but delayed in the centre. Where there was initial union on the ulnar side, all progressed to complete union, including two patients with displaced fractures. Four out of five patients with initial union on the radial side had displaced fractures, and three of these went on to non-union. We conclude that in those patients with partial union of a scaphoid fracture, if union is seen on the ulnar side, the fracture is likely to unite completely, whereas if there is partial union on the radial side, there is a high risk of non-union.
