How accurate and reliable are doctors in estimating fracture angulation?

This study assessed the accuracy of doctors in estimating fracture angulation. Radiographs of fractured wrist and forearm of varying angulations were shown to all grades of doctors in the speciality of trauma and orthopaedics. They were asked to estimate the angulation at the fracture site without using a goniometer. The estimates were analysed for accuracy and variability. This study showed that doctors have a mean error of 8-9 degrees and had poor agreement with themselves and others. We recommend the use of a goniometer to assess fracture angulation.

From presentation to publication: the natural history of orthopaedic abstracts in the United Kingdom.

BACKGROUND: Up to 63% of the chapters in major orthopaedic textbooks use the results from abstracts that have been presented at international orthopaedic meetings. METHODS: Orthopaedic abstracts were reviewed that were presented at the 1997 and 1998 meetings of the British Orthopaedic Association and other specialist orthopaedic meetings. The number of abstracts that had gone on to a full text publication was assessed and changes in study design or outcome were determined. RESULTS: Of the 415 abstracts 137 (33.0%) went on to full text publication. Abstracts presented at the British Orthopaedic Association were significantly more likely to go on to full text publication than abstracts from the other meetings studied. The mean time to publication was 15.6 months. Sample sizes in unpublished studies were smaller (mean 129.8 subjects compared with a mean of 191.4 subjects for published studies). Of full text papers, 19.0% differed regarding study design from the abstract presented at the initial meeting and 10.9% had published different results. Randomised controlled trials had the highest rate of later full text publication (53.6%) followed by observational studies (32.8%), basic science studies (31.4%), and case reports (6.7%). CONCLUSIONS: In comparison with a study from North America, similar numbers of abstracts presented at meetings finally became published as full text articles, the abstracts had fewer authors, more often included randomised controlled trials and follow up data, and had fewer changes to the results. It is questionable whether the inclusion of such results from abstracts presented at international meetings by major orthopaedic textbooks should be undertaken before full text publication.

The extended scope physiotherapist in orthopaedic out-patients - an audit.

INTRODUCTION: We undertook an audit of the activity of the extended scope physiotherapists (ESPs) in our unit. We assessed their activity against three benchmark data: (i) independent assessment and management by the ESP of 85% of patients seen by them; (ii) no patient to be re-referred to a surgeon with the same problem; and (iii) patient satisfaction rate of 89%. PATIENTS AND METHODS: All new referrals seen by the ESPs over the 6-month period between July 2002 and December 2002 were included in the audit. Patient medical records were reviewed retrospectively. Patients were contacted by telephone 12 months after their initial clinic appointment to obtain patient satisfaction scores. RESULTS: In the 6-month period, 150 patients (75 male, 75 female) were seen. Their median age was 43.5 years (range, 17-85 years). Their main complaints related to the spine (42%), knee (33%), shoulder (18%), or other site (7%). The ESPs saw and managed 82/150 patients (55%) independently. Consultant review was required for 81% of shoulder cases, 34% of knee cases and 11% of back cases. GPs re-referred 4/150 patients (3%). We successfully contacted 126 patients by telephone: 97 (77%) were satisfied with their management by ESPs. Of patients who were dissatisfied, 76% did not see a consultant at any stage in their management. CONCLUSIONS: ESPs fulfilled a useful role in our orthopaedic out-patient clinic particularly in the back clinic. The percentage of independently managed patients was much lower than the figure quoted in the literature. We suspect that the published literature does not reflect modern referral patterns and recommend that time for review of new patients seen by ESPs should be factored into consultant's clinic time. Patients' expectations may be a barrier to achieving greater levels of patient satisfaction.

Balancing priorities in the management of hip fractures: guidelines versus resources.

BACKGROUND: About 60,000 patients are treated for hip fractures each year in the UK and the incidence is increasing. The majority of these patients are elderly and sick, and delay to operation may be fatal. The National Confidential Enquiry into Peri-Operative Deaths (NCEPOD) guidelines aim to improve quality of care for such patients. However, we present an audit highlighting the importance of balancing the implementation of such guidelines with available local resources to ensure that established priorities in the care of these patients remain paramount. METHODS: The 2001 NCEPOD report recommends that pre-operative transthoracic echocardiography be performed in patients who have evidence of aortic stenosis in order to identify those requiring invasive monitoring and high dependency unit care postoperatively. RESULTS: We have assessed the impact of the implementation of these guidelines on surgery for fractured neck of femur at our hospital, auditing both delay to surgery and the effect of the investigation on subsequent management. In the period studied prior to the introduction of the NCEPOD guidelines, no patients underwent pre-operative echocardiography. Subsequent to their introduction, 10% of patients underwent the investigation, which in the current study did not alter management but did delay surgery by 4-8 days in all cases. CONCLUSIONS: For such guidelines to be implemented, adequate resources should first be provided. In the absence of these resources, clinicians must balance the need for adequate pre-operative assessment with the need for urgent surgery.

The femoral cement mantle in three total hip replacements.

We measured the size and volume of the femoral broaches and stems supplied with three commercial total hip replacement (THR) systems (JRI Furlong, Biomet Stanmore, and Howmedica Exeter). Using an in vitro method, we created cement mantles that could be directly measured. The broaches supplied with the Biomet Stanmore and the Howmedica Exeter systems allowed the creation of significantly thicker cement mantles than the JRI broaches and stems (Stanmore mean thickness = 1.7 mm, defects at 3% of measurement sites; Exeter mean thickness = 2.0 mm, no defects; JRI mantles mean thickness = 0.9 mm, cement defects at 29% of measurement sites). We conclude that, in vivo, the broaches supplied with the Stanmore and Exeter systems are significantly larger than the corresponding stems, and will excavate a cavity large enough to accommodate the appropriate femoral stem surrounded by an intact cement mantle.

The rate of instrument breakage during orthopaedic procedures.

The current study investigates instrument breakages during both emergency and elective orthopaedic surgery. Over a 2 year period a total of 7,775 procedures were performed. We found that 14 instruments were broken during 12 operative cases. Drill bits accounted for the largest proportion of breakages (11/14), and a specialist registrar was the lead surgeon in the majority (8/12) of cases. Only one case had a consultant as the lead surgeon. In seven cases the broken bit of the surgical instrument was left in the patient. Documentation of this peri-operative complication was deficient, and the patient was often not informed.

Management of paediatric clavicle fractures--is follow-up necessary? An audit of 346 cases.

We investigated the incidence of complications following childhood clavicle fractures and the necessity for follow-up in fracture clinic after the first orthopaedic consultation. We found that review in fracture clinic has no impact upon the outcome of clavicle fractures and complications such as non-union, mal-union or neurovascular problems are exceptionally rare. We concluded that there is no need for follow-up of children with isolated, uncomplicated clavicle fractures. These patients should be discharged after their first assessment in fracture clinic.

Cryotherapy compared with Robert Jones bandage after total knee replacement: a prospective randomized trial.

Sixty patients undergoing total knee replacement were randomized to receive either a cold compression dressing (Cryo/Cuff, Aircast, UK) or a modified Robert Jones bandage immediately after surgery. The cold compression dressing was used for a minimum of 6 h per day throughout the hospital stay, and the modified Robert Jones bandage remained in place for 48 h from the time of operation. The 2 groups of patients were compared during their hospital stay for blood loss, range of movement, pain scores and need for analgesia. No difference was found between the 2 groups except for less blood loss in the surgical drains in the cold compression group (P < 0.05). Postoperative complications were seen in both groups, but no complication was associated with either the cold compression dressing or the modified Robert Jones bandage.

Photographic wound documentation after open fracture.

More than 3000 open fractures occur in UK each year. They require early assessment and meticulous treatment in order to avoid devastating complications. The British Orthopaedic Association and British Association of Plastic Surgeons Working Party recommend that an instant photograph be taken of an open wound prior to the application of a dressing. The dressing can then remain undisturbed until the definitive surgical debridement is performed in theatre. Such practice reduces nosocomial infection. Fifty-one accident and emergency departments were surveyed by the means of a telephone questionnaire. Forty-one percent were unable to photograph an open fracture wound. A further 20% had no access to a camera outside of office hours. The cheap, simple and effective recommendations of the Working party are not being followed.
