Introduction. Approximately 2,000 Skeletal transcutaneous osseointegration (STOI) procedures have been performed worldwide as of 2020, more than half of which have been performed by the Osseointegration Group of Australia using a press-fit technique with either ILP or OPL implant designs. Despite the consistently demonstrated clinical benefits, concerns regarding potential complications following STOI have slowed its widespread adoption. As more patients are followed for a longer period of time, longitudinal studies have confirmed complication rates are very acceptable, similar to those of total ankle and total elbow replacements. One of the major risk category is implant
Aims. The timing of when to remove a circular frame is crucial; early
The Latarjet procedure is a well described method to stabilize anterior shoulder instability. There are concerns of high complication rates, one of these being a painful shoulder without instability due to screw irritation. The arthroscopic changes in the shoulder at time of screw
Introduction. Traditionally, radiological union of fractures treated with an Ilizarov frame is confirmed by a period of dynamization - destabilisation of the frame for a period prior to
Introduction. Retention and
Introduction. Circular frames in the lower limbs have been removed by Specialist nurses in our clinics for the past 20 years using Entonox. This standard of care has helped reduce the burden of health care cost by avoiding
Introduction. External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent
Olecranon Osteotomy is a common approach used in the management of intraarticular distal humerus fractures. Significant complication rates have been associated with this procedure, including non-union rates of 0–13% and implant
Aim. To evaluate the efficiency of pulse lavage combined with electrical fields to remove biofilm from a metallic surface. Method. Using a 12-well culture plate designed for the application of electrical fields, strains of S. epidermidis were incubated at each well for 24 hours at 37ºC. After incubation, supernatant culture medium was removed, and each well was filled with 3ml of normal saline. Six different models were compared: a) control, b) low-pressure pulse lavage, c) high-pressure pulse lavage, d) pulsed electrical fields, e) low-pressure pulse lavage in combination with pulsed electrical fields, and f) high-pressure pulse lavage in combination with pulsed electrical fields. In all cases, exposure time was set to 25 seconds. In the electrical field models, 50 pulses were applied. After exposure, each bottom electrode was scraped carefully to release adhered bacteria. Subsequently, different dilutions of biofilm removed were spread onto Müller Hinton agar plates and incubated for 24h at 37 ºC, and colony-forming units (CFU) per milliliters were counted. Bacterial counts were then compared to the control model. Results. High-pressure pulse lavage combined with pulsed electrical fields showed the greatest biofilm
Aim. There is a lack of data supporting the use of doxycycline as a single agent after removing infected orthopaedic metalwork. We evaluated the efficacy and safety of doxycycline compared with other single antibiotic regimens used at our specialist orthopaedic hospital. Methods. A retrospective observational study including all adult patients diagnosed with an orthopaedic metalwork infection due to staphylococci. All patients were managed with the

Background. In order to restore the neutral limb alignment in total knee arthroplasty (TKA), surgical procedure usually starts with removing osteophytes in varus osteoarthritic knees. However, there are no reports in the literature regarding the exact influence of osteophyte
Introduction. Superficial pin site infection is a common problem associated with external fixation, which has been extensively reported. However, the incidence and risk factors with regards to deep infection is rarely reported in the literature. In this study, we investigate and explore the incidence and risk factors of deep infection following circular frame surgery. For the purpose of this study, deep infection was defined as: persistent discharge or collection for which surgical intervention was recommended. Materials and Methods. Retrospective review of all patients whom underwent frame surgery between 1. st. of April 2015 to 1. st. April 2019 in our unit with a minimum of 1 year follow up following frame
Aim. To date, the value of culture results after a debridement, antibiotics and implant retention (DAIR) for early (suspected) prosthetic joint infection (PJI) as risk indicators in terms of prosthesis retention is not clear. At one year follow-up, the relative risk of prosthesis
Aim. The treatment of fracture-related infections (FRI) focuses on obtaining fracture healing and eradicating infection to prevent osteomyelitis. Treatment guidelines include
The well-fixed cemented femoral stem and surrounding cement can be challenging to remove. Success requires evaluation of the quality of the cement mantle (interface lucency), position of the stem, extent of cement below the tip of the stem and skill with the specialised instruments and techniques needed to remove the stem and cement without perforating the femur. Smooth surfaced stems can usually be easily removed from the surrounding cement mantle with a variety of stem extractors that attach to the trunnion or an extraction hole on the implant. Roughened stems can be freed from the surrounding cement mantle with osteotomes or a narrow high speed burr and then extracted with the above instruments. Following this, the well-fixed cement mantle needs to be removed. Adequate exposure and visualization of the cement column is essential to remove the well-fixed cement without damage to the bone in the femur. This is important since fixation of a revision femoral component typically requires at least 4 cm of contact with supportive cortical bone, which can be difficult to obtain if the femur is perforated or if the isthmus damaged. Proximally, cement in the metaphyseal region can be thinned with a high speed burr, then split radially and removed piecemeal. It is essential to remember that both osteotomes and high speed burrs will cut thru bone easier than cement and use of these instruments poses a substantial risk of unintended bone
Introduction. Methoxyflurane can cause hepatotoxicity and nephrotoxicity at anaesthetic doses but has excellent analgesic properties and no nephrotoxic effects in patients without preexisting disease. Approved for use in the UK and Ireland in 2015, it is currently being used in emergency departments for analgesia during fracture reduction. During the Covid emergency, with theatre access severely restricted and many patients unwilling to use inhaled Nitrous oxide, Penthrox had the potential to provide adequate pain relief to aid frame
