Aim. Hand-disinfection (HD) is the most effective infection-prevention-measure. HD-performance of health care professionals (HCP) is usually evaluated by compliance observations (CO). The Hawthorne effect (HE) (HCP behave differently under observation) is considered to systematically increase HD-compliance-rates during CO. However, little is known about the specifications of the HE in health care settings. We hypothesized that, due to hand-hygiene`s known impact on patient safety and infection-prevention, the HE does not affect HD performance during direct patient care in patient-rooms. Method. We conducted a prospective observational trial on an 18-bed surgical intensive care unit (ICU), a 12-bed surgical intermediate care unit (IMC) and a 36-bed surgical normal ward (NW) in a university hospital in Germany. Dispensers of hand sanitizers were equipped with an electronic monitoring system (EMS) (GWA Hygiene, Germany), which recorded the number of HDs per patient hour (HD/PH) and time and location of hand-disinfections. Locations were categorized as follows: 1. Patient rooms (PR); 2. Utility- and waste-disposal-rooms (UWR) and 3. Other rooms (hallways, kitchen, toilets etc.) (OR). Additionally trained infection-control-staff performed hand-hygiene CO according to WHO's Five Moments. The HD/PH during CO was compared to the HD/PH during the same time-periods without CO. Additionally the ratio between HD/PD-change during CO and mean-HD/PD of each ward during the study-period was determined in percentages. Descriptive and analytical statistics were calculated using R. P-values ≤ 0.05 were regarded as significant. Results. 587.128 HD were electronically recorded during the study-period (February 2022 to May 2023) and CO took place on 72 days. We recorded a significant increase of HD/PH during CO on all three wards in PRs (ICU: 21%, p<0.001; IMC: 11%, p=0.029; NW: 49%, p=0.047). Furthermore we detected a significant increase of HD/PH during CO on ICU (10%, p<0.001) and IMC (11%, p=0.033) in ORs. CO did not significantly affect HD/PH in ORs on NW and in UWR on all three wards. Conclusions. In our setting, the number of hand-disinfections per patient-hour was significantly increased during compliance-observations especially in patient-rooms, where hand-hygiene is most crucial for infection-prevention. This indicates a lower everyday compliance to WHO`s hand-hygiene indications during patient care than determined by compliance-observations. Acknowledgments.

Aims

The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups.

The subject of noise in the operating theatre was recognized as early as 1972 and has been compared to noise levels on a busy highway. While noise-induced hearing loss in orthopaedic surgery specifically has been recognized as early as the 1990s, it remains poorly studied. As a result, there has been renewed focus in this occupational hazard. Noise level is typically measured in decibels (dB), whereas noise adjusted for human perception uses A-weighted sound levels and is expressed in dBA. Mean operating theatre noise levels range between 51 and 75 dBA, with peak levels between 80 and 119 dBA. The greatest sources of noise emanate from powered surgical instruments, which can exceed levels as high as 140 dBA. Newer technology, such as robotic-assisted systems, contribute a potential new source of noise. This article is a narrative review of the deleterious effects of prolonged noise exposure, including noise-induced hearing loss in the operating theatre team and the patient, intraoperative miscommunication, and increased cognitive load and stress, all of which impact the surgical team’s overall performance. Interventions to mitigate the effects of noise exposure include the use of quieter surgical equipment, the implementation of sound-absorbing personal protective equipment, or changes in communication protocols. Future research endeavours should use advanced research methods and embrace technological innovations to proactively mitigate the effects of operating theatre noise.

The critical relationship between airborne microbiological contamination in an operating theatre and surgical site infection (SSI) is well known. The aim of this annotation is to explain the scientific basis of using settle plates to audit the quality of air, and to provide information about the practicalities of using them for the purposes of clinical audit. The microbiological quality of the air in most guidance is defined by volumetric sampling, but this method is difficult for surgical departments to use on a routine basis. Settle plate sampling, which mimics the mechanism of deposition of airborne microbes onto open wounds and sterile instruments, is a good alternative method of assessing the quality of the air. Current practice is not to sample the air in an operating theatre during surgery, but to rely on testing the engineering systems which deliver the clean air. This is, however, not good practice and microbiological testing should be carried out routinely during operations as part of clinical audit.

Aims

Our primary aim was to establish the proportion of female orthopaedic consultants who perform arthroplasty via cases submitted to the National Joint Registry (NJR), which covers England, Wales, Northern Ireland, the Isle of Man, and Guernsey. Secondary aims included comparing time since specialist registration, private practice participation, and number of hospitals worked in between male and female surgeons.

The August 2024 Hip & Pelvis Roundup³⁶⁰ looks at: Understanding perceived leg length discrepancy post-total hip arthroplasty: the role of pelvic obliquity; Influence of femoral stem design on revision rates in total hip arthroplasty; Outcomes of arthroscopic labral treatment of femoroacetabular impingement in adolescents; Characteristics and quality of online searches for direct anterior versus posterior approach for total hip arthroplasty; Rapid return to braking after anterior and posterior approach total hip arthroplasty; How much protection does a collar provide?; Timing matters: reducing infection risk in total hip arthroplasty with corticosteroid injection intervals; Identifying pain recovery patterns in total hip arthroplasty using PROMIS data.

Aims

Conventional patient-reported surveys, used for patients undergoing total hip arthroplasty (THA), are limited by subjectivity and recall bias. Objective functional evaluation, such as gait analysis, to delineate a patient’s functional capacity and customize surgical interventions, may address these shortcomings. This systematic review endeavours to investigate the application of objective functional assessments in appraising individuals undergoing THA.

Trauma, across the United Kingdom, is managed using several software, paper based lists on Microsoft Word/Excel or Teams. There is usually poor handover or no handover in a standard format- during the on call, in the trauma meetings or in the wards. The software in the market for trauma management are not cost friendly or adaptable to local demands. The alternatives like Microsoft WORD based lists are fraught with their own problems. We endeavoured to make our trauma management effective. A Quality Improvement Project was done. The goals to achieve at end of a year were:. Daily Trauma Handover in standardised format >90%. Ward Handover in standardised format >90%. Availability of outcomes of patients in clinic >80%. Reduction of paper usage >90% at the end of six months. Availability of updated “outliers” information >90% at the weekend ward round. Documentation from the Trauma Meeting > 90%. On-Call documentation in standardised format >90%. Doctor Satisfaction >75% in terms of: ease of us;, searchability of patient; ward round experience; morning trauma meeting experience; handover experience; inter-specialty communication; reliability; daily time saving; on-call time saving; patient care/safety; overall satisfaction. We used Microsoft Sharepoint List to manage our trauma workload and have named the tool as “The List”. The List has achieved all objectives as above in one year's time, except Outlier information which was at 67% in a recent PDSA (Plan-Do-Study-Act) cycle. The survey showed excellent doctor satisfaction and 90% respondents felt that The List saved an hour or more during the on-call and also during the ward rounds. We conclude that The List is a very powerful tool making trauma meetings efficient and handover effective. It is indigenous, adaptable, safe, sustainable, cost neutral and easy to use

Aims

Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures.

INTRODUCTION. Simulation plays an important role in surgical education and the ability to perfect surgical performance. Simulation can be enhanced by adding various layers of realism to the experience. Haptic feedback enhances the simulation experience by providing tactile responses and virtual reality imagery provides an immersive experience and allows for greater appreciation of three-dimensional structures. In this study, we present a proof-of-concept haptic simulator to replicate key steps of a cervical laminoplasty procedure. The technology uses affordable components and is easily modifiable so that it can be used from novice through to expert level. Custom models can be easily added ensuring the simulator can be used in a wide range of orthopaedic applications from baseline education through to day of surgery pre-operative simulation. METHOD. We used the Unity Game Engine, the 3D Systems “Touch” Haptic Feedback Device (HFD), and a Meta Quest VR headset. Our system uses a number of complex algorithms to track the shape and provide haptic feedback of a virtual bone model. This allows for simulation of various tools including a high-speed burr, Kerrison rongeur and intraoperative X-rays. RESULTS. Our simulator replicates the tactile sensations of bone-burring tasks. Although we focused on the cervical laminoplasty procedure, the system can load data from CT scans, enabling the simulation of multiple other procedures. The parts cost of our system, $10,000 NZD, is a fraction of the cost of traditional surgical simulators. DISCUSSION. Our simulator reduces financial barriers to accessing orthopaedic simulators. Trainees can perform hands-on practice without compromising patient safety. The immersive nature of VR, combined with realistic haptic feedback, enables trainees to develop the dexterity and three-dimensional understanding of detailed bony work. Further refinements are needed before we can perform validation studies on our system. CONCLUSIONS. We present an affordable surgical simulator capable of simulating bony surgical procedures in a VR environment using haptic feedback technology and consumer-grade components. ACKNOWLEDGEMENTS.

Introduction. Frame HI is the #Days for device removal/cm. IM Nail HI is less relevant (31–45 D/cm). Albizzia HI was 33 D/cm (1991–2003). Patients felt fine approximately 1M after end of lengthening (EoL), resuming normal life and sports. This sometimes resulted in implants fractures (e.g. skying before bone fusion). Ideally, the full fusion should occur at the EoL. We decided to shorten the HI to reach this target, optimising all parameters. Materials & Methods. The evolution of care has been monitored over a 32-year clinical experience with a fully weight-bearing nails (Albizzia then G-nail). Monitoring was with X-rays, DEXA, blood bone activity, and in London with special 5G CBCT Scans. We implemented several changes in the Care of patients and measured them according to the ‘Five Principles’ (stability, function, ‘Roads-vascular supply’, ‘Materials-calories’ and ‘Workers-BFC’, with actions on food intake, activity levels and on muscle and bone vascular growths. Results. Preop: training (vascularity, muscle force). Op & Postop: spine morphine, IM sawing preserving BFC, controlled hypo-pressure, low hydration, 50 cm leg elevation, walking, resistance bike, full motion (drainage, muscle reactivation), discharge 3–4h postop (including bilateral). Postop daily intense gym training. POD07-21: Distraction increased to fight non-linear hyper-ossification (44–50 mm gain at POD30) +/- aided by NSAIDs. HI decreased to 12–20D/cm, sometimes 8D/cm with some ‘soft fusion’ during lengthening, hardening within 1W after EoL. Conclusions. The surgeon is not a passive X-rays observer, but has an active role in changing the healing speed and decreasing HI for patient safety. Electro/Magnetic nails (torque 1 Nm) may be clocked by bone fusion, which does not occur with the G-Nail (19 Nm). An holistic vision for patients and treatments at several levels is essential to accelerate bone healing, and to return fast to full normal life, after a short ‘lengthening parenthesis’
