Introduction

The health sector contributes the equivalent of 4.4% of global net emissions to the climate carbon footprint. It has been suggested that between 20% and 70% of health care waste originates from a hospital's operating room, the second greatest component of this are the textiles used, and up to 90% of waste is sent for costly and unneeded hazardous waste processing.

Waste from common orthopaedic operations was quantified, the carbon footprint calculated, and cost of disposal assessed. A discussion of the circular economy of textiles, from the author of the textile guidance to the Green Surgery Report follows.

Methods

The amount of waste generated from a variety of trauma and elective orthopaedic operations was calculated across a range of hospital sites. The waste was separated primarily into clean and contaminated, paper or plastic. The carbon footprint and the cost of disposal across the hospital sites was subsequently calculated.

Abstract

Background

During COVID-19 pandemic, there has been worldwide cancellation of elective surgeries to protect patients from nosocomial transmission and peri-operative complications. With unfolding situation, there is definite need for exit strategy to reinstate elective services. Therefore, more literature evidence supporting exit plan to elective surgical services is imperative to adopt a safe working principle. This study aims to provide evidence for safe elective surgical practice during pandemic.

Methods

This single centre, prospective, observational study included adult patients who were admitted and underwent elective surgical procedures in the trust's COVID-Free environment at Birmingham Treatment Centre between 19th May and 14th July’2020. Data collected on demographic parameters, peri-operative variables, surgical specialities, COVID-19 RT-PCR testing results, post-operative complications and mortality. The study also highlighted the protocols it followed for the elective services during pandemic.

Most long-term follow-up studies report retrospective data, the quality of which remains limited due to their inherent biases. Prospective databases may overcome these limitations, however, feasibility and costs limit their application. To date there exists a paucity of evidence-based literature on which recommendations can be made for the ideal length of follow-up for spinal deformity research. Therefore, our aim was to evaluate the added value of follow-up of patients beyond 2 years following surgery for AIS.

A database registry evaluating surgical outcomes for all consecutive AIS patients with post-op data-points of 6 months, 1 year, 2 year, and 5 year was analysed. Surgeon-reported complications, SRS-22 scores, and radiographic data were evaluated. Complications requiring surgical or medical intervention were compared between patients in whom complications developed within 2 years to those in which newly developed complications occurred between >2–5 years.

536 patients were analysed. SRS-22 scores significantly improved at 2 years post-op with no change at 5-year follow-up. Overall complication rate was 33.2% with majority occurring within 2 years (24.8%). The rate of complications occurring >2–5 years requiring intervention was significantly lower than those requiring intervention within 2 years of surgery (4.7% vs 9.7%, p=0.000), however was not negligible. The most common newly observed complication beyond 2 years was pain (1.9%), followed by surgical site infection (SSI) (1.3%) and implant issues (0.56%). There were no significant differences in the rates of crankshaft (p=0.48), implant issues (p=0.56), pseudarthrosis (p=0.19), and SSI (p=0.13) between the 2 time points.

Although majority of complications following AIS surgery occurs within 2 years, a non-negligible rate of newly observed complications occur at >2–5 years post-op. Specifically crankshaft, pseudarthrosis, implant issues, and SSI have similar rates of occurrence at these 2 time points.

Natural history of AIS >30° in skeletally mature patients is poorly defined. Studies reporting rates and risk factors for progression are predominantly of large curves in immature patients. Our aim was to determine the rate of curve progression in AIS following skeletal maturity, any associated changes in SRS-22 scores, and identify any potential predictors of curve progression.

Patients enrolled in a prospective, longitudinal, multicentre non-surgical AIS database were evaluated. All patients had minimum 2 year follow-up, idiopathic scoliosis >30°, and were skeletally mature. SRS-22 functional outcome scores and radiographic data were compared at baseline and 2-year follow-up. Patients were divided into 3 groups based on curve size: A=30°-39°, B=40°-49°, C= >50°. Curve progression was defined as any change in curve magnitude.

There were 80 patients, majority females (93.8%) with a mean age of 16.5+/−0.16. Mean BMI was 21+/−0.31 with 15.1% overweight. Mean major cobb at baseline was 38.3°+/−0.88°. At 2 year follow-up 46.3% of curves had progressed an average 3.4°+/−0.38°. Of curves that progressed, patients in group A had the largest mean rate of progression followed by group B. SRS-22 scores on average declined significantly over 2 years in this cohort (4.23 to 4.08; p=0.002). Patients who progressed had on average a more significant decline in SRS outcome scores compared to those that did not (p=0.018, p=0.041 respectively), with the most significant change noted in the Self-Image domain (p=0.03). There was no significant difference in the change in SRS scores over 2 years based on curve size. Univariate analysis did not identify any factors predictive of curve progression in this cohort.

Skeletally mature patients with AIS >30°may continue to have a risk of progression at a mean rate of 1.7°/yr and significant decline in SRS-22 outcome scores, in particular Pain and Self-Image, over time.

Introduction

Dislocation is one of the leading causes of revision after primary total hip arthroplasty (THA). Polyethylene wear is one of the risk factors for late dislocations (>2 years). It can induce an inflammatory response resulting in distension and thinning of the pseudocapsule, predisposing the hip to dislocation. Alternatively, eccentric seating of the femoral head in a worn out socket may result in an asymmetric excursion arc predisposing the hip to impingement, levering out and dislocation. Highly cross linked polyethylene has a significantly lower wear rate as compared to conventional polyethylene. Incidence of late dislocations has been shown to be significantly greater with conventional polyethylene bearings as compared to ceramic bearings. However, there is no literature comparing the risk of dislocation between ceramic- on- ceramic (CoC) bearings with metal/ceramic- on- cross linked polyethylene (M/CoP) bearings and this was the aim our study

Methods

Data regarding revision for dislocation after primary THA for osteoarthritis (OA) between September 1999 and December 2013 was obtained from the Australian Orthopaedic Association National Joint Replacement Registry (AOA NJRR). Revision risk for dislocation was compared between CoC, CoP, and MoP bearings. Only those THAs with 28 mm, 32 mm, or 36 mm heads were included in the study.

There is strong evidence to support the use of bisphosphonates in the prevention of osteoporotic fractures. There has, however, been growing concern that prolonged use of bisphosphonates can lead to the development of atypical femoral fractures and can protract healing time.

We conducted a retrospective study looking at all femoral fractures between 2011–2013. Of 109 patients, 12 were diagnosed with atypical femoral fractures. The mean age of presentation was 69 (52–92). Five patients held no history of falls and presented with hip pain. The remaining seven sustained minor falls. Seven patients were on bisphosphonates on presentation. Bisphosphonates were discontinued in five cases and continued in two. Bisphosphonates commenced in one patient who subsequently developed second fracture. All fractures were managed with intramedullary nailing. Healing time was prolonged in all cases (mean healing time 7.3 months). Three patients needed further surgeries to achieve union.

Overall, we observed that patients with prolonged bisphosphonate intake were more susceptible to atypical fractures with a delayed recovery time.

Increasing awareness amongst medical professionals may aid timely diagnoses and subsequent referrals to orthopaedics. Recognition of these fractures may also permit early discontinuation of bisphosphonates, which may prevent future fractures and reduced healing times.

Background

Venous thromboembolism (VTE) is a common complication of pelvic and acetabular fracture fixation. There is, however, currently limited data to guide clinical decisions on thromboprophylaxis choice in these patients.

Methods

This is a prospective study with retrospective analysis of all the patients who were admitted to the Northern General Hospital between August 2009 and March 2011. 2 consultants using same technique and peri-operative regime carried out all procedures. All patients were administered prophylactic enoxaparin and those who were admitted via another hospital had a pre-operative Doppler scan. Post-operatively all patients were commenced on warfarin, or low molecular weight heparin (enoxaprin) if warfarin was contra-indicated, and was continued for three months after discharge.
