Current fracture-clinic models, especially in the advent of reductions in junior doctors hours, may limit outpatient trainee education and patient care. We designed a new model of fracture-clinic, involving an initial consultant led case review focused on patient management and trainee education.

Prospective outcomes for all new patients attending the redesigned fracture-clinic over a 3-week period in 2010 (n=240) were compared with the traditional clinic in the same period in 2009(n=296). Trainees attending the fracture clinic completed a Likert questionnaire (1 [strongly dissagree] − 5 [strongly agree]) assessing the adequacy of education, support, staff morale & standards of patient care.

The percentage of cases given consultant input increased significantly from 33% in 2009 to 84% in 2010 (p< 0.0001), while the proportion of patients requiring physical review by a consultant fell by 21% (p< 0.0001). Return rates were reduced by 14.3% (p< 0.013) & utilization of the nurse lead fracture clinic improved by 10.1% (p< 0.0028). These improvements were most marked in the target group ?StR2 (24.2% & 22.3% respectively). There were significant improvements in staff perception of their education from 2 to 4.75 (p< 0.0001), provision of senior support from 2.38 to 4.5 (p=0.019), morale from 3.68 to 4.13 (p=0.0331) & their overall perception of patient care from 3.25 to 4.5 (p=0.0016). A&E staff found the new style clinic educational, practice changing & that it improved interdisciplinary relations, but did not interfere with their A&E duties.

Our model of fracture-clinic redesign has significantly enhanced consultant input into patient care without additional funding. In addition, we have demonstrated increased service efficiency and significant improvements in staff support, morale and education. In the face of current economic and training challenges, we recommend this new model as a tool for enhancing patient and trainee experiences.

Outcomes for all new patients attending the redesigned fracture-clinic over a 3-week period in 2010 were compared with the traditional clinic in the same period in 2009. Health professionals completed a Likert questionnaire assessing their perceptions of education, support, standards of patient care and morale before and after the clinic redesign.

309 and 240 patients attended the clinics in 2009 and 2010 respectively. There was an increase in consultant input into patient management after the redesign (29% versus 84%, p<0.0001), while the proportion of patients requiring physical review by a consultant fell (32% versus 9%). The percentage of new patients discharged by junior medical staff increased (17% versus 25%) with a reciprocal fall in return appointments (55% versus 40%, p<0.0005). Overall, return appointment rates fell significantly (55% versus 40%, p=0.013). Staff perception of education and senior support improved from 2 to 5, morale and overall perception of patient care from 4 to 5.

Post-operative regimes involving the use of intra-articular local anaesthetic infiltration may allow early mobilisation in patients undergoing total knee arthroplasty. Few studies have evaluated such regimes outside specialist arthroplasty units. We aimed to determine whether an enhanced recovery programme including the use of local anaesthetic administration could be adapted for use in a district general setting.

Following introduction of this regime to our unit, 100 consecutive patients undergoing primary total knee arthroplasty were reviewed. 56 patients underwent a standard analgesic regime involving a general or spinal anaesthetic and oral analgesics post operatively (group1). 48 patients underwent the newly introduced regime, which included pre-operative counselling, peri-articular local anaesthetic infiltration at operation and intra-articular local anaesthetic top-up administration post-operatively for 24 hours (group 2). Length of stay, post-operative analgesic requirements, and range of knee motion post-operatively were compared.

Median length of stay was less for patients in group 2 compared with those in group 1 (4 days compared to 5 days, p<0.05). Patients in group 2 required lower total doses of opiate analgesia post-operatively. 90% of patients in group 2 were ambulant on the first post operative day, compared with less than 25% of patients in group 1. Mean knee flexion on discharge was greater in patients in group 2 compared with those in group 1 (85 degrees compared with 75 degrees). No infective complications from intra-articular catheter placement were observed. However, technical difficulties were encountered during the introduction period, including loss of catheter placement, leakage of local anaesthetic and adaptation of nursing time for top-up anaesthetic administration.

A rehabilitation regime involving local anaesthetic infiltration for total knee arthroplasty can successfully be adapted for use in a district general setting. Our results suggest if initial technical difficulties are overcome, this regime can provide effective postoperative analgesia, early mobilisation and reduced hospital stay.

Introduction: The aim of the study was to investigate the reproducibility and accuracy of templating total hip arthroplasty with on-screen digital radiographs using three commercially available software packages, and compare the results to templating on-screen using acetates.

Method: In twenty patients undergoing hybrid total hip arthroplasty, pre-operative templating for acetabular size, femoral offset and stem size were performed by three independent observers using on-screen digital radiographs by three different techniques. The magnification of the on-screen images were adjusted appropriately by using a metal coin marker of known size attached to the patient at time of acquiring the radiographs. These images were used to template for total hip arthroplasty using three commercially available digital templating software packages (Orthoview™ Workstation, Southampton, UK, Ferrania LifeWeb TraumaCad™, Berkshire, UK and mdesk™ software suite, RSA Biomedical, Sweden). The templated results were compared with the component sizes subsequently implanted and to templating on-screen using acetates. Intra- and inter-observer reproducibility were assessed using the Intraclass Correlation Coefficient (ICC).

Results: Intra-observer reproducibility was good for the three software systems with almost all ICC values > 0.70. Inter-observer reproducibility was less consistent, which may reflect familiarity and may improve with a “learning curve”. All three software systems tended to slightly undersize the acetabular size.

Discussion: For both reproducibility and accuracy, all the three commercial systems were comparable with templating using the acetate template method. Digital templating using software packages is an acceptable method of templating. Templating software packages are certainly an attractive proposition but until installation & maintenance costs are reduced, “traditional” templating with acetates remains the most effective option.

This study prospectively evaluated the outcome of manipulation under anaesthesia and hydrodilatation as treatments for adhesive capsulitis. A total of 36 patients (38 shoulders) were randomised to receive either method, with all patients being treated in stage II of the disease process.

The mean age of the patients was 55.2 years (44 to 70) and the mean duration of symptoms was 33.7 weeks (12 to 76). Eighteen shoulders (17 patients) underwent manipulation under anaesthesia and 20 (19 patients) had hydrodilatation. There were three insulin-dependent diabetics in each group. The mean visual analogue score in the manipulation under anaesthesia group was 5.7 (3 to 8.5; n = 18) before treatment, 4.7 (0 to 8.5; n = 16) at two months (paired t-test p = 0.02), and 2.7 (0 to 9; n = 16) at six months (paired t-test, p = 0.0006). The mean score in the hydrodilatation group was 6.1 (4 to 10; n = 20) before treatment, 2.4 (0 to 8; n = 18) at two months (paired t-test, p = 0.001), and 1.7 (0 to 7; n = 18) at six months (paired t-test, p = 0.0006). The visual analogue scores in the hydrodilatation group were significantly better than in the manipulation under anaesthesia group over the six-month follow-up period (p < 0.0001).

The mean Constant score in those manipulated was 36 (26 to 66) before treatment, 58.5 (24 to 90) at two months (paired t-test, p = 0.001) and 59.5 (23 to 85) at six months (paired t-test, p = 0.0006). In the hydrodilatation group it was 28.8 (18 to 55) before treatment, 57.4 (17 to 80) at two months (paired t-test, p = 0.0004) and 65.9 (28 to 92) at six months (paired t-test, p = 0.0005). The Constant scores in the hydrodilatation group were significantly better than in the manipulated group over the six-month period of follow-up (p = 0.02).

The range of movement improved in all patients over the six months, but was not significantly different between the groups. At the final follow-up, 94% of patients (17 of 18) were satisfied or very satisfied after hydrodilatation compared with 81% (13 of 16) of those receiving a manipulation.

Most of our patients were treated successfully, but those undergoing hydrodilatation did better than those who were manipulated.

Study Design: Retrospective review of 55 subjects who for various clinical indications had sequential MRI scans

Summary of Background data: Changes in the vertebral end plate are frequently associated with degenerative disc disease. These are called Modic changes. The changes were first classified into two types. Type I changes include decreased signal intensity on T1-weighted and increased signal intensity on T2-weighted images. In type II, signal intensity is increased in both T1- and T2-weighted sequences. Type I changes are assumed to be a result of fibrovascular replacement of subchondral bone and type II changes are the manifestation of fatty replacement of subchondral bone and are considered to be chronic. These changes can be separated only on magnetic resonance imaging (MRI). If bone sclerosis is extensive, signal intensities are decreased in both T1- and T2- weighted images, and this change in the end plate is called type III change. It is again assumed that these endplate changes represent a process that is progressive (Type I converts to Type II converts to Type III). To our knowledge there is little evidence to support such assumptions.

Objective: To investigate the hypothesis that Modic changes are a progressive degenerative process.

Subjects: The average time interval between MRI scans was two years. No subjects had had surgical intervention. The lumbar vertebral endplates were classified using the Modic system and the results compiled to provide further data on the natural history of these endplate changes.

Results: Of the endplates that had Modic type I changes on the first MRI scan, 6% had reverted to a normal MRI endplate appearance on subsequent scan. Of those with Modic type II appearance 18% were normal or type I on subsequent scan.

Conclusions: This data would not support the hypothesis that Modic changes observed on MRI are a progressive degenerative process.

A prospective clinical investigation to determine the optimum knee flexion angle for the ‘skyline’ patellofemoral joint radiograph.

Plain radiography of the patello-femoral joint includes the axial or ‘skyline’ radiograph. The optimum knee flexion angle for making this image remains unclear.

We therefore performed a prospective clinical study in which patients underwent three skyline radiographs with knee flexion angles of 30(or minimal flexion), 50 and 90 degrees. The patients were new patients, aged between 12 and 30, presenting to a knee clinic with anterior knee pain. Two observers evaluated the radiographs, making a standardised series of measurements. Blinding was organised so that the observers were unable to use any information other than the radiographic image alone. One observer evaluated all the films on two separate occasions to allow calculation of intra- and interassessor agreement.

There were 67 knees from 46 patients. There was a high level of intra- and inter-observer agreement. There were a number of patients in which the radiographic appearance of the patello-femoral varied markedly between the different views; in all cases the abnormality was best demonstrated by the 30-degree view. There were however a number of minimal flexion views in which the film contained incomplete information because part of the patello-femoral joint was missing from the image.

We conclude that whilst a minimal flexion skyline view is the most sensitive method for the detection of patellar tilt and subluxation, not all knees can be successfully imaged at the required position. A flexible approach is therefore needed, to obtain satisfactory images at minimal flexion.
