Antibiotic-eluting calcium compounds can be used to deliver antibiotics in the management of prosthetic joint infection (PJI). Described omplications include wound drainage, heterotopic ossification(HO) as well as hypercalcaemia which is potentially life threatening. The aim of this study is to assess the incidence of hypercalcaemia and other complications between two calcium based antibiotic delivery systems. A retrospective study was performed. Thirty two patients treated with Stimulan or Cerament Calcium based antibiotic delivery system between August 2014 to January 2017 were included. Seven patients received Cerament, 21 cases received Stimulan and one patient received both. The volume used as well as pre- and post-operative serum calcium were recorded as well as any wound related complications and radiologic changes suggestive of heterotopic ossification. The postoperative serum adjusted Calcium were taken weekly during the initial post operative period. Patients with overactive parathyroid disease and pre-existing renal disease were excluded.Aim
Method
Revision surgery and debridement and implant retention are recognised approaches for managing prosthetic joint infections (PJI) but may not always be indicated. If the patient is unable to have or declines surgery, prolonged suppressive antibiotic therapy (PSAT) is an option. This study aims to define outcomes of PSAT from a single unit. A retrospective study was performed. All cases of PJI involving the hip or knee between 2012 and 2017 were identified from our institutional database and cross referenced with patient notes. One hundred and seventy eight cases were identified. Of these, 23 (12.9%) (10 hips, 13 knees) were treated with PSAT. Infection was diagnosed based on the MSIS criteria in all cases and all cases were managed by a multidisciplinary team which included specialist microbiologists. One case of long term antifungal therapy was additionally identified. Co-morbidity was assessed using the Charlson co-morbidity index. Exacerbations of infection and need for further surgery were recorded.Aim
Method
Instability accounts for one third of revision total hip arthroplasty(rTHA) performed in the United Kingdom. Removal of well-fixed femoral stems in rTHA is challenging with a risk of blood loss and iatrogenic damage to the femur. The Bioball Universal Adaptor (BUA) (Merete, Germany), a modular head neck extension adaptor, provides a mechanism for optimisation of femoral offset, leg length and femoral anteversion. This can avoid the need for femoral stem revision in selected cases. There is a relative paucity of clinical data available with the use of this device. The aim of this study is to present the clinical results and rate of instability following revision with this head neck adaptor at a minimum of two years' follow up.Introduction
