The purpose of this prospective study was to evaluate pain levels, range of motion, patient activity and satisfaction after radioscapholunate (RSL) arthrodesis. This was in association with distal scaphoid excision and complete resection of the triquetrum. The non-union rate for radioscapholunate arthrodesis was examined and the results compared with previous studies. Twenty-three patients (14 males and nine females) with an average age of 47 (range 26-73) years underwent RSL fusion for post-traumatic osteoarthritis, rheumatoid arthritis and Kienböck's disease of the lunate with a mean follow-up of 32 (range 13-70) months. The absolute prerequisite for any of these groups of patients was a functional midcarpal joint which was assessed pre-operatively with radiographs and intra-operatively prior to RSL fusion. The average flexion to extension motion changed from 66 degrees to 57 degrees . The ulnoradial range of motion also increased to 43 degrees from a pre-operative value of 22 degrees . The patients visual analogue pain scores reduced from an average of 64 to 28 (p = 0.01). Nineteen patients had no restriction in activity and all but one was satisfied with the outcome. All patients remained in full time employment with ten returning to some form of sport. RSL fusion with excision of the distal pole of the scaphoid and the entire triquetrum led to minimal reduction in the flexion-extension arc of motion and an increase in the ulnoradial arc. There was also good pain relief and maintenance of a patient's function. Memory staples are also an effective method of securing fusion in the wrist obtaining similar results to that seen in forefoot surgery.
Most studies comparing the biomechanical properties of different meniscal repair systems have simply investigated load to failure. Meniscal tissue is highly anisotropic, and far weaker under tension in the radial direction. Radially oriented loading to failure may not therefore be the most physiologically relevant in vitro test for repair of circumferential tears, and determining gapping across repair sites under cyclical loading at lower loads may be of greater importance. Using bovine menisci, vertical circumferential incisions were repaired using a simple vertical 2-0 PDS suture, Meniscal Arrow, Meniscal Fastener or T-Fix. Repairs were tested by simple loading to failure in a materials testing machine, and by cyclic loading between 5 and 10 N for 25 cycles. Initial gapping across the repairs was measured using a digital micrometer, and the increase in gapping under cyclic loading measured using a Differential Voltage Reluctance Transducer. The mean loads to failure for each of the repair groups were: sutures 72.7 N, Arrows 34.2 N, Fasteners 40.8 N and T-Fix 49.1 N. The load to failure was significantly greater with sutures than with Arrows or Fasteners. The mean gapping across the repairs for each of the repair groups after 25 loading cycles were: sutures 3.29 mm, Arrows 2.18 mm, Fasteners 3.99 mm and T-Fix 3.47 mm. The mean gapping was significantly less with Arrows than with Sutures, Fasteners or T-Fix. These results confirm that meniscal repair by suturing gives the highest load to failure, but show that Arrows give superior hold under lower loads, with the least gapping across repairs under cyclic loading of the four methods tested.
We have investigated nine patients with cemented Furlong (JRI, London, UK) titanium hip replacements who presented with early pain despite a well-fixed, aseptic prosthesis. All were followed up clinically and radiologically at regular intervals. Pain was located in the thigh and was worse at night. Radiographs showed cortical hypertrophy of the femur around the tip of the stem. Eight of the nine patients subsequently required single-stage revision using an uncemented prosthesis, which relieved the pain. At revision, the pH of the tip of the stem was found to be highly acidic with macroscopic evidence of corrosion consisting of multiple layers of titanium oxides when studied by X-ray dispersive analysis. Cemented titanium implants have a potential for crevice corrosion leading to cortical hypertrophy and intractable pain.
ObjectiveThe aim of this study was to establish the number of unnecessary preoperative blood tests undertaken on ASA Grade 1 patients undergoing minor/moderate orthopaedic trauma surgery.DesignReview of all ASA1 patients who had been operated on the trauma lists for three consecutive months.SettingUK Teaching Hospital.ParticipantsPatients with ages ranging between 16 and 60 years, and undergoing a minor or moderate trauma operation.Main outcome measuresThe type and number of blood tests were established and any abnormal results were checked for clinical significance and whether the result altered patients' management. The cost of each blood test was calculated so that potential savings could be identified.ResultsA total of 127 patients (60 males, 67 females, average age 34) fulfilled our inclusion criteria. Ninety-five patients (75%) had either one or more preoperative blood tests of which 41% were abnormal but of no clinical significance.ConclusionFrom the results of our study, we conclude that preoperative blood tests are unnecessary in Grade 1 ASA patients undergoing minor/moderate orthopaedic trauma surgery. Unnecessary blood tests can waste time, money, resources and overburden laboratory staff.
This paper investigates the feasibility of a telephone clinic follow-up service for patients undergoing carpal tunnel decompression. Six hundred and thirty patients were recruited over a 2-year period and we assessed their outcome and satisfaction level in the service, using a pre-determined questionnaire 6 weeks following surgery. The telephone clinic was overseen by a surgical care practitioner. We followed up 598 patients (93%) in total, and found 42 patients to be dissatisfied with the service (7%). These patients were referred for outpatient consultation and investigation. Most patients were satisfied with their surgical outcome and found the telephone clinic service to be convenient and effective. Cost analysis calculations estimated a potential saving of pound 45,958 over the 2-year period when compared to standard outpatient consultation. This model has been developed in our trust to follow up patients undergoing similar minor hand surgery.
If a high suspicion of a soft tissue or bone tumour is suspected from the history, examination and plain radiograph, then early referral to a specialist centre is recommended where relevant, high-quality investigations can be arranged in a short time leading to a planned biopsy, confirmation of diagnosis and definitive treatment at an earlier stage.
