Since 2003 Trauma and Orthopaedic trainees in the UK and Ireland have routinely submitted data recording their operative experience electronically via the eLog-book. This provides evidence of operative experience of individuals and national comparisons of trainee, trainer, hospital and training programme performance. We have analysed trauma surgery data and established standards for training. By January 2008 there were over 4 million operations logged. Operations performed and uploaded since 2003 have been included. Each trainee’s work is analysed by ‘year-in-training’. Data on levels of supervision, missed opportunities (where the trainee assisted rather than performed the operation) was analysed. The average number of trauma operations performed annually by trainees was 109, 120, 110, 122, 98 and 84 (total 643) for YIT one (=ST3) to six (=ST8) respectively. There were only 22% of missed opportunities throughout six years of training. A high level of experience is gained in hip fracture surgery (121 operations) and forearm (30), wrist (74) and ankle (47) operative stabilisation over the six years. However, the average number of tibial intra-medullary nails (13), external fixator applications (12) and childrens’ elbow supracondylar fracture procedures (4) performed is low. We are also able to identify trainees performing fewer operations than required during their training (two standard deviations or more below the mean for their YIT). We expect a trainee to have performed at least 255, 383, 473, and 531 trauma operations at the end of YIT three to six respectively. The eLogbook is a powerful tool which can provide accurate information to support in-depth analysis of trainees, trainers, and training programmes. This analysis has established a baseline which can be used to identify trainees who are falling below the required operative experience.
The first United Kingdom In-training Examination (UKITE) was held in 19 training programmes during December 2007. The aims of the project are to offer a national, online examination (providing immediate results to trainees) and to allow practice for the ‘real’ FRCS T&
O examination with similarly formatted questions based on the UK T&
O curriculum. All Speciality training years (StR2, StR3 and above, and all SpRs) and all deaneries will participate in the future. A total of 450 trainees sat this first examination. This is an online exam (accessed through the eLogbook/OCAP website) which is voluntary and has no bearing on RITA outcomes. To take part in the exam trainees were asked to provide 3 questions for a bank which can be used in subsequent years for both UKITE and the FRCS T&
O examination. The exam was 3 hours and questions were of multi-choice (MCQ) and extended matching question (EMQ) style covering all aspects of orthopaedics. Correct answers and explanations were available to the trainee after their answer had been submitted. Final scores ranged from 35% to 92%. Mean scores increased from 48% (StR2) to 73% in SpR year 5 (StR7 equivalent). This was followed by a drop off in performance in the final year of training. Three candidates had equal top scores at 92%. 97% stated they would sit the UKITE again and 93% felt there was educational benefit. The length and level of difficulty of the exam was felt to be satisfactory. Improvements were suggested for question quality. The UKITE is a powerful tool for self-assessment of trainees. This analysis establishes a baseline for future years.
National Institute for Clinical Excellence (NICE) guidelines on venous thromboembolic (VTE) prophylaxis for patients undergoing orthopaedic surgery recommend that all inpatients be offered a low molecular weight heparin (LMWH). Linked hospital episode statistics of 219602 patients were examined to determine the rates of complications following lower limb arthroplasty for the 12-month periods prior to and following the publication of these guidelines. This was compared with data from the National Joint Register (England and Wales) regarding LMWH usage during the same periods. There was a significant increase in the reported use of LMWH (59.5 to 67.6%, p<
0.01) between the two periods. However, 90-day VTE events increased following both total hip (THR, 1.67% to 1.84%, p=0.06) and knee replacement (TKR, 1.99% to 2.04%, p=0.60). 30-day return to theatre rate for infection fell following TKR, but increased after THR. In addition, there were increases in rates of thrombocytopenia, which was significant following THR (p=0.03). Recommendations from NICE are based on predicted reductions in VTE events, reducing morbidity, mortality and costs to the National Health Service. Early results in orthopaedic patients are unable to support these predictions.
This group of patients were compared with previous data collected over a 6 month period (Jan to Mar 2007 and Oct to Dec 2005) from the same hospitals for infection rates in Lower Limb Arthroplasty using 3 doses of Cefuroxime 750mg as antibiotic prophylaxis.
Surgical site infection was detected in 9 THRs (2.2%) and 2 TKRs (0.44%) in the study group as compared to infection in 13 THRs (3.1%) and 12 TKRs (2.9%) in the control group. Using the Fisher Exact test the infection rates in THRs were not significantly different between the 2 groups (p value – 0.52) but the infection rates were significantly reduced in the study group for TKRs (p value – 0.005). There were no complications with the use of Gentamicin as antibiotic prophylaxis. Cefuroxime is known to promote Clostridium difficile infection and was removed from the hospital pharmacy to help meet a UK government targets to reduce the incidence. The rate of Clostridium difficile infection was reduced within the hospital with the use of single dose antibiotic prophylaxis although other measures to reduce its incidence were also introduced.
This is recommended for routine use in all elective joint replacements as it is safe, effective and easy to administer.

The return to theatre was 2.42% (28/1157) after introduction of Gentamicin as compared with 1.85% (37/2005) [p value – 0.172] before this. This was a cause for concern, although not a significant difference.

The rate of Clostridium difficile infection was reduced within the hospital with the use of single dose antibiotic prophylaxis although other measures to reduce its incidence were also introduced.
However, be wary of increased rate of return to theatre following use of gentamicin. Further period of evaluation and study is needed before it is recommended for routine use in present or modified form.
There have been no large comparative studies of the blood levels of metal ions after implantation of commercially available hip resurfacing devices which have taken into account the effects of femoral size and inclination and anteversion of the acetabular component. We present the results in 90 patients with unilateral articular surface replacement (ASR) hip resurfacings (mean time to blood sampling 26 months) and 70 patients with unilateral Birmingham Hip Resurfacing (BHR) implants (mean time 47 months). The whole blood and serum chromium (Cr) and cobalt (Co) concentrations were inversely related to the size of the femoral component in both groups (p <
0.05). Cr and Co were more strongly influenced by the position of the acetabular component in the case of the ASR, with an increase in metal ions observed at inclinations >
45° and anteversion angles of <
10° and >
20°. These levels were only increased in the BHR group when the acetabular component was implanted with an inclination >
55°. A significant relationship was identified between the anteversion of the BHR acetabular component and the levels of Cr and Co (p <
0.05 for Co), with an increase observed at anteversion angles <
10° and >
20°. The median whole blood and serum Cr concentrations of the male ASR patients were significantly lower than those of the BHR men (p <
0.001). This indicates that reduced diametral clearance may equate to a reduction in metal ion concentrations in larger joints with satisfactory orientation of the acetabular component.
Introduction: The threshold for internal fixation of thoracolumbar junction fractures is controversial. Most authorities would agree that indications would include neurological deficit and severe deformity. The definition of severe deformity many would regard as a kyphus angle of 20° or more and/or compression of more than 50% of the anterior body height. Patients are only assessed on supine films alone. The aim of this study was to ascertain whether weight-bearing films altered the deformity and if so did this subsequently alter management. Methods: A prospective study of patients who had suffered a fracture of the thoracolumbar junction (T11- L2). All patients who had a neurological deficit or a kyphus angle of greater than 20° and/or greater than 50% anterior body collapse were excluded. Only patients with a deformity less than the above were entered into the study. These patients then had weight-bearing views (standing or sitting) as soon as they had developed trunk control. A kyphus angle of greater than 20° or more than 50% body collapse were used as a criteria for fixation. Results: 16 patients were entered into the study over a one year period. Five (31% ) of the 16 patients had a significant increase in their deformity on weight-bearing films that caused them to pass the threshold for fixation, and subsequently had surgery . Conclusion: The authors recommend that weight-bearing views should always be taken on fractures of the thoracolumbar spine if conservative treatment is being considered.
To determine whether resection of osteophyte at TKR improves movement, 139 TKRs were performed on knees with pre-operative posterior osteophyte. Randomisation was to have either resection of distal femoral osteophyte guided by a custom made ruler or no resection. After preparation of the femoral bone cuts the ruler measuring 19 mm was placed just proximal to the posterior chamfer cut. The proximal end of this ruler marked the bone to be resected and this was performed using an osteotome at 45 degrees. Knees randomised to no resection had no further femoral bony cuts. Three months after implantation the patients had range of motion assessed. One hundred and fourteen suitable knees were assessed, with 59 knees (57 patients) in the resection group and 55 knees (54 patients) in the no resection group. Full extension was more likely in the resection group (62%) than the group without resection (41%)(p=0.08). Flexion to at least 110 degrees was, however, less in the resection group (37%) than the no resection group (54%) (p=0.09). Our study failed to show a statistically significant difference if the bony osteophyte is removed. There were however sharp trends, with statistically a one in ten chance these results would be different if the trial was repeated. Although there is no indication as to the cause of improved extension this could be explained by the release of the posterior capsular structures allowing full extension. The reduction in flexion is harder to explain and this may be due to increase in perioperative trauma and resultant swelling, possibly with fibrosis. Range of movement, particularly flexion, is known to improve up to 1 year post-operatively and assessment of these groups at that stage would be beneficial.
Research is regarded as an important part of higher surgical training, and forms an important component of in training assessment. Currently, there is little planning of research at a regional level. The aim of this study was, first, to evaluate the attitude of trainees towards research in order to highlight and understand difficulties. The second aim was to determine the level of support for a proposed research database to help organise regional research activity. All trainees in a single region (39) were asked to complete a questionnaire handed out during two regional teaching days. 28 Questionnaires were returned. Nine percent of trainees have a higher degree with a further 35% on progress. Each trainee had an average of three (range 0–6) ongoing research projects. Over half the trainees had abandoned research projects. Most trainees stated an interest in research and felt that research was an important part of training and should be assessed in the RITA. Most trainees felt that research would dictate the quality of their consultant jobs. Almost every trainee stated that changing posts every eight months, as well as distance between hospital sites, made it difficult to complete projects. Every trainee felt that the ethical committee process causes significant delays in progress. Most felt that access to statistical advice was poor. Almost all trainees would welcome a regionally co-ordinated research database. Trainees abandon research for various reasons. We propose that a research database would serve the primary function of linking trainees with consultants with quality research projects. Junior trainees would be encouraged to join the system and choose a project. The research section of the RITA could then focus on the progress of that project(s). Secondary aims would be coordinating access to advice on funding, statistics and ethics committee applications.
The aim of this study was to establish the ability of an invasive fibre-optic probe to measure intra-muscular pH, pCO2, pO2, HCO3-−, ambient temperature, base excess and O2 saturation. The secondary aim was to determine the effect of elevation of the limb on these parameters. Fibre-optic probes were introduced into the anterior compartment muscle of the leg in five volunteers via 16G cannulae. After equilibration the limb was monitored for 11min with the volunteer supine on an examination couch. The limb was elevated to 22cm (Braun frame) and then 44cm for the same time. Subsequently the leg was returned to 22cm and supine. All volunteers followed this set protocol. Continuous recording of all indices was made throughout. Data was stored to a personal computer for analysis. Similar trends were observed across all subjects for all parameters. The mean pO2 when lying flat was 27mmHg (S.D.7.4). Elevation to 22cm increased muscle pO2 to 33 mmHg (S.D. 5.8). Further elevation to 44 cm resulted in a reduction in muscle pO2 to a level below that measured when supine. When the limb was returned to 22cm the pO2 trend reversed, the level improving. Returning to the supine position the pO2 returned to the level seen at the start of monitoring. This novel probe gives reproducible measures of pH, pCO2, pO2, HCO3−, ambient temperature, base excess and O2 saturation. Results indicate that elevation to 22cm improves muscle oxygenation; a height of 44cm seems detrimental. This technique may be applicable in surveillance for compartment syndromes and muscle ischaemia.
