There is little knowledge in surgeons about the guidelines for prophylactic antibiotics in patients with prosthetic joints when undergoing a dental procedure. This study confirms this and there is need for robust and universal guidelines given the disastrous nature of prosthetic infection. Infection as an indication for revision has increased to 12 % of the total revisions (NJR 9th report). However, it is next to impossible to find out the cause for a delayed prosthetic infection. With increasing number of arthroplasty procedures, is there a need for prophylactic antibiotics in patients with prostheses?Summary
Introduction
The clinical significance of serum metal ion levels alone in patients with stemmed MoM hip arthroplasty remains uncertain. This study aims to measure the metal ion levels in patients with unilateral and bilateral hip arthroplasty to see whether or not the patients with bilateral hips have higher metal ions. All the patients with bilateral MoM hip arthroplasty were identified from the research database. These patients were then matched with those in a similar age group who had a unilateral hip arthroplasty, but same University of California Los Angeles (UCLA) activity score. The UCLA activity scores along with other hip scores have been previously gathered for all the patients. Both sets of patients then had measurement of serum cobalt and chromium levels. The results were analyzed and compared.Introduction:
Patients and Methods
Infection as an indication for revision has increased to 12% of the total revisions (UK NJR 9th report). However, it is next to impossible to find out the cause for a delayed prosthetic infection. With increasing number of arthroplasty procedures, is there a need for prophylactic antibiotics in patients with prostheses? At London Knee Meeting 2012, a total of 163 surgeons were asked to take part in a survey. This was to find out if they knew of any existing guidelines for prophylaxis for dental procedures, if there was a need to practice more uniformly, and if they recommend such prophylaxis to their patients routinely. The grade of the surgeon and their experience in years was also noted.Introduction:
Methods:
The awareness of MoM hips in the general public, one would expect, to be good, given the media coverage. This study aims to look at the perceptions and knowledge of patients who have already got a MoM arthroplasty. All the patients who have had a MoM hip arthroplasty from Nov 2003 to the end of 2007 were identified from the database. Postal questionnaires were sent to all the patients, the responses received and analyzed. Those patients who had symptoms and those who fulfilled MHRA criteria were invited to a clinic for further surveillance.Introduction:
Methods:
Intraoperative cell salvage involves the collection of blood directly from the operative field. The purpose of this study was to determine if its use reduces the need for postoperative allogenic blood transfusion, assess any adverse events and its effect on duration of postoperative stay in primary hip arthroplasty. We prospectively examined the effect of intraoperative cell salvage on the need for postoperative allogenic blood transfusion. Between February 2009 and August 2010, a total of 77 patients who underwent primary total hip arthroplasty were included in the study, under the care of the senior author (KB). All patients had a diagnosis of osteoarthritis. Intraoperative cell salvage was used in 38 patients and not used in 39 patients. We prospectively collected data on patient demographics, ASA grade, preoperative and postoperative haematological features, number of units of packed red cells transfused and the volume of intraoperative reinfused cell salvaged blood. Total inpatient stay and any postoperative adverse events were recorded.Introduction:
Patients and Methods:
Plating remains the most widely employed method for the fixation of displaced diaphyseal clavicle fractures. The purpose of this study was to assess the efficacy and outcomes of diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood clavicle pin. We conducted a retrospective analysis of all diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood pin between February 2004 and March 2010. Sixty-eight procedures were carried out on 67 patients. Functional outcome was assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and an overall patient satisfaction questionnaire.Purpose
Methods
Volar locking plates have revolutionised the treatment for distal radius fractures. The DVR (Depuy) plate was one of the earliest locking plates which were used and they provided fixed angle fixation. Recently, newer volar locking plates, such as the Aptus (Medartis), have been introduced to the market that allow the placement of independent distal subchondral variable-angle locking screws to better achieve targeted fracture fixation. The aim of our study was to compare the outcomes of DVR and Aptus volar locking plates in the treatment of distal radial fractures. Details of patients who had undergone open reduction and internal fixation of distal radii from October 2007 to September 2010 were retrieved from theatre records. 60 patients who had undergone stabilisation of distal radius fractures with either DVR (n=30) or Aptus (n=30) plate were included in the study.Background

Government figures show a trend of increasing incidence in motorcycle trauma in the UK over the last decade. These patients often have multiple injuries and place a significant burden on the admitting units. In the face of changes to health service funding, with the introduction of Payment by Results, we wanted to determine the true cost of treating these patients in the setting of a District General Hospital. We undertook a retrospective case-note review of all the motorcyclists involved in road traffic accidents (MRTAs) requiring admission for treatment in 2004. Patients were identified using the hospital computer system. A supplementary telephone survey was also undertaken to retrieve information not previously recorded. The following parameters were analysed: demographic and admission details, motorcycle and accident details, admitting specialty, injury pattern, nature and number of investigations, treatment, outcome and cost.Introduction
Methods
Inter-phalangeal (IP) joint fusion of lesser toes has been quite a commonly done procedure using Kirchner wires (K-wire). Infection from the K-wire site has been significant complication. We present a retrospective study of 21 toes of arthrodesis of IP joints of lesser toes using a cannulated screw. The indications were either claw toe or a hammer toe. All the cases that were done from February 2006 to June 2008 were included. There were 21 toes in 15 patients at an average age of 69 years (range 54 – 80). There were 20 females and only one male. The distribution of second, third and fourth toes were 12, 6 and 3 respectively. Nine toes were right sided and 12 were left sided. They were followed for an average of 14 months (range 2–30). There was one case of superficial cellulitis (4.8%) which has responded well to antibiotic therapy. There were two cases where the prominent screws had to be removed at 4 and 5 months post-operative period. Good arthrodesis has been achieved by this time. Clinical arthrodesis was achieved at 4.5 months (range 3–7) and radiological arthrodesis was achieved at 5.2 months (range 4 – 9). All have been discharged at the time of this study. Good correction of deformities with well healed arthrodesis was achieved. Most patients reported pain free toes. We have found this technique to be very useful alternative with good results and less complications.
Intra-articular steroid injection has been widely used for relief of pain in Osteoarthritis. Recent studies show an increasing rate of infection in these patients following hip arthroplasty. We have reviewed our cohort of patients to see if they are susceptible to higher infection rate. We reviewed a cohort of 167 consecutive hips that had at least one injection with a 40mg triamcinolone acetonide and 4ml 0.5% bupivacaine mixture to relieve the symptoms of hip osteoarthritis or to clarify a diagnosis of hip arthritis between January 1997 and Novem-ber 2004 were reviewed. A total of 37 hips (36 patients) that subsequently proceeded to have a total hip arthroplasty were selected as our study group. There was a minimum of a one-year follow up. The rate of infection in our initial cohort of patients following a hip injection was 0.60% (1 hip) which resulted in repeated washouts and a subsequent total hip arthroplasty with a good outcome. On review of the 37 hips, one was revised due to a deep infection secondary to staphylococcus epidermidis. Four were revised for continued instability and pain with no evidence of infection either prior to or during revision. When deep infection is taken as an endpoint, cumulative survival at 7.5 years is 0.968 (95% confidence interval of 1 to 0.905). The total survivorship of this cohort if all revisions are included is 0.852 at 7.5 years (95% confidence interval of 0.730 to 0.974). The revision rate due to a deep infection in our study is 2.7%. We conclude that patients who have a total hip arthroplasty after a hip injection do not have an adversely high rate of deep infection.
