Background and purpose: As hip fracture patients are common and constitute an increasing health problem it is important to use available resources effectively and provide high quality care. Correct treatment can start in the ambulance with administration of oxygen, pain relief and intravenous glucose liquid according to the Lean Production concept. The basis of Lean Production is that the employees themselves develop their work as a natural part of the job. In the case of health care, this involves learning what it are that really benefits the patients, what it is that creates added value. Anything that does not benefit the patients is to be removed.

The aim of this study was to improve the preopera-tive care of hip fracture patients.

Subjects : During the period 2007-04-01 to 2007-12-31 totally 365 hip fracture patients were consecutively admitted to the University Hospital. Of them 117 (mean age 82.8) patients were included in the project and 248 patients (mean age 81.3) were controls.

Method: Patients with a suspected hip fracture (shortened and externally rotated leg) were supposed to be included in the study. Exclusions criteria were medical unfit patients with for example ongoing hearth problems or stroke. Already in the ambulance the patient’s identification was established, blood samples were drawn and electrocardiography was taken. At admission to the hospital the ambulance personnel directly followed the patient to the x-ray unit and further to the orthopaedic ward without passing the acute and emergency unit.

Results: Patients included in the project felt that they were in safe hands and were satisfied with the handling time from the ambulance until they were at the ward. This time has diminished from 4 hours to half a hour. The mean time from admission to surgery was 29 hours for patients in the control group versus 21 hours for patients included in the project. Furthermore, the personnel at the x-ray unit are satisfied with the new organisation since there are more personnel lifting a better pain relieved patient from the trolley to the x-ray table.

Conclusion: When we are working in multi professional and multi functional teams with the LEAN concept, safety and quality of care can be improved if the preop-erative care of hip fracture patients is speeded up.

Preoperative planning for Total Hip Arthroplasty has been acknowledged as a vital step to facilitate a successful outcome. Templating ascertains the dimensions and positioning of the implants, minimizing both intraoperative and postoperative complications. The purpose of this study is to compare the accuracy of digital templating to acetate templating in the preoperative planning of Total Hip Arthroplasty.

Preoperative planning was performed on 40 consecutive patients (mean age = 70.5 years), undergoing Total Hip Arthroplasty. Digital templating was performed by the Hip fellow 1, using Orthoview software (Jacksonville, FL, USA) and recorded the sizes of the cup and stem for each of the 40 patients. Subsequently, the same 40 patients were templated by Hip fellow 2, with X-rays done with a lead marker of known size by the side of the femur, using, acetate templating method. Templating results were compared to the actual sizes of the implants used, as noted in operative notes. Templating scores for the acetabular cup were 40% (16/40) with digital templating and 50% (20/40) with acetate templating. The templating scores for stem were 28% (11/40) with digital templating and 90% (36/40) with acetate templating. The differences between templating and actual implant sizes were plotted in Bland–Altman plot. Acetate templating proved to be statistically, significantly more accurate than digital templating (p value= 0.0083).

Our results indicate that the traditional acetate method is solid and valid to use for preoperative planning. This method is accurate and offers a more affordable option for preoperative templating. Although the templated size is one, there is a tendency to increase cup size to use bigger heads, which is the recent National Joint Registries trend. We recommend that acetate templating should be used as the default option.

Introduction

The association between preoperative opioid use and adverse outcomes after total hip arthroplasty (THA) has been reported. However, a quantitative assessment used to evaluate the combined effect of controlled substance use and define a threshold for adverse outcomes after THA has not been established. The current study aimed to identify the association between the NarxCare Score (NCS) (indicative of controlled substance use) and length of stay (LOS), discharge disposition, 90-day emergency department (ED) visits, readmission, and reoperation after primary THA, necessary to identify a preoperative NCS threshold for adverse outcomes.

In a recent study, 54.5% of patients reporting to arthroplasty clinics in the US were obese. We performed a recent literature review to determine how obesity impacts outcomes in total hip and knee arthroplasty and what must be done to improve outcomes in the obese arthroplasty patient. Specifically, obese patients have shown increased rates of infection, dislocation, need for revision, wound dehiscence, increased operative time and prolonged hospital stay. Additionally, obese TKA patients have been shown to have increased rates of aseptic loosening, thromboembolic events, wound complications, and cardiopulmonary events. Worsening severity of obesity seems to correlate with worsening outcomes and super obesity (BMI>50) has been identified as an independent risk factor for complications. Patients with BMI>35 have shown to be 6.7 times more likely to develop infection after TKA. Patients with BMI>40 have a 3.35 times higher rate of revision for deep infection than those with BMI<35. The odds ratio for major complications increases dramatically beyond BMI>45. How can we improve outcomes in the obese patient? Preoperative care for the obese patient involves nutritional counseling, incorporating weight loss methods, physical therapy, metabolic workup and diagnosis and management of frequent comorbid conditions (OSA, DM2, HTN, HLD, malnutrition, renal failure). Identifying and managing comorbidities is especially important given that some comorbidities such as malnutrition have been shown to be as strong or even stronger an independent risk factor for postoperative TJA complications than obesity. In some cases higher complications were seen which some authors attribute to bariatric patients remaining in a catabolic state after weight loss.  . We know that obesity and its associated comorbid conditions do have worse outcomes and increased complications in TJA patients. We also know that complications proportionately increase with increasing severity of obesity. The super-obese population is at the greatest risk of complication following TJA and preoperative screening and management is essential in reducing complications. Although weight loss is important, bariatric data has shown that it does not solve the problem of obesity in itself and the patient's metabolic state is likely a more important issue. Implant selection is important and strong consideration should be given to avoiding direct anterior approach in the THA obese patient. Understanding of obesity specific complications and treatment options is crucial for patient counseling and optimization to ensure successful treatment in obese TJA patients

We present the use of the Orthopaedic POSSUM Score and Surgical Risk Score (SRS) to identify optimal time for fracture neck of femur surgery. The objective of this study was to identify the physiological status of patients at admission and compare the results of operative physiological condition and differences in predictive and actual operative outcomes. 1238 consecutive hip fractures from Jan 2005 to July 2006 at 3 hospitals were assessed. Collection of demographic, admission and operative POSSUM, and SRS scores, fracture pathology, physiological status, and postoperative outcome were conducted. In total, 1031 (83.3%) patients had surgery. The median age was 72.6 (range 55–95, mean 68). Majority had significant systemic multiple co-morbidity (78%), an average ASA score of 3.3. POSSUM predicted 18.7% (n= 194) of death at 30 days, where as the surgical risk score predicted 13.8% (n=142 deaths), the actual mortality was 11.7% (n=120). The difference between admission and operative physiological POSSUM score increased with operative delay (see table 1). Physiological scores greater than 30 had a 67.8% risk of 30-day mortality. 361 patients had an increase in physiological score from admission to operation, resulting in higher analgesic requirements and reduced mobility scores (P< 0.005). These patients had a 12.6% increase in mortality when compared with patients operated earlier with a similar initial score (P< 0.005). Furthermore delayed surgery (> 48 hours) lead to reduced in return mobility, function, increased wound infections and other medical complications. Possum and SRS over predict operative mortality, but are useful in prioritising their time of surgery. Declining operative physiological POSSUM scores indicate room for improvement in preoperative care, and for specific protocols if surgery has to be delayed to prevent further physiological deterioration, and induce optimal functional outcomes

Purpose: Wrist fractures are often seen in elderly subjects who cannot generally tolerate aggressive fixation of unstable fractures. Percutaneous intra-focal pinning (Kapandji) is usually employed. The purpose of this study was to compare the classical treatment of unstable extra-articular fractures of the lower quarter of the radius with posterior displacement with a modified pinning technique. Material and methods: This prospective radiological study concerned two groups of randomised patients aged 30 – 70 years who were hospitalised for surgical treatment of Pouteau-Colles fractures. In the first group, all patients were treated by the classical intra-focal technique using one or two dorsal pins and one lateral pin (group K). In the second group, all patients were treated by fixation with one or two infrafocal dorsal pins and a third pin inserted transfocally (group KM). Preoperative care, anaesthesia, and postoperative care (21 days immobilisation, pin removal at 45 days) were the same in both groups. The following anatomic measurements were made on the radiographs at day 1, 21, 45, and last follow-up: radial inclination on the lateral and AP views, bistyloid line. Results: Group K included 49 patients, mean age 45 years. Group KM included 46 patients, mean age 54 years. There was no statistical difference between groups for age, gender, side, type of fracture. Radial inclination on the AP view was 19.2 (10–27 in group KM and 23.2 (19-30) in group. On the lateral view, radial inclination was 0 (−11 to 20) in group KM and −5.7 (−25 to 2) in group K. The proportion of bistyloid lines considered satisfactory was not different between groups. Discussion: Infra-focal pinning can have limitations for maintaining reduction to bone healing. The Kapandji technique modified by use of a third transstyloid pin appears to provide better stabilisation of unstable fractures of the lower extremity of the radius, particularly in older subjects who cannot tolerate aggressive surgery. This preliminary study should be completed by a radio-clinical analysis in a larger number of patients to confirm these results
