Surgery for pelvic or acetabular fractures carries a high risk of deep-vein thrombosis (DVT). Reports indicate that fondaparinux is a more effective thromboprophylactic agent than low molecular weight heparin (LMWH) after major orthopaedic surgery. We prospectively evaluated a new protocol for DVT prophylaxis using fondaparinux. Patients and methods. One hundred and eight patients with pelvic or acetabular fractures were randomised to receive either fondaparinux or enoxaparin. Specific review points included the primary end-point of clinical
Introduction. Corrosion at the modular junction of the femoral component in total hip arthroplasty (THA) was considered as a cause of adverse local tissue reaction in recent years. We reported three adverse local tissue reaction cases after total hip arthroplasty using the same modular neck stem in this study. Materials and Methods. We have been essentially using the same titanium modular neck stem system and the same combination bearing surface of 26mm cobalt chromium (CoCr) head and highly cross linked polyethylene line for primary total hip arthroplasty since November 2009. Three female showed adverse local tissue reaction and had additional surgical treatment after the THA. Results. Two patients showed asymptomatic focal osteolysis on X-ray at the Gruen zone 1 around three years after the THA (one case also showing pseudo tumor around lessor trochanter). One patient presented symptomatic
Objectives. C-reactive protein(CRP) Used as screening test for acute periprosthetic joint infection has high sensitivity and low specificity. So there are many reasons except acute infection after total knee arthroplasty to elevate CRP level but it is unclear what reasons exactly were concerned. We therefore performed this study to determine the Causes of elevated CRP level in the early-postoperative period after primary total knee arthroplasty. Methods. Between 2005 and 2013, 502 patients undergone primary total knee arthroplasty were included. We excluded patients performed total knee arthroplasty with inflammatory arthritis and revision total knee arthroplasty, We measured the serial CRP levels in the all cases and then found cases with CRP level show elevation-depression-elevation pattern(bimodal graph) or >23.5mg/dl. We analyzed causes of elevated CRP level of that. Results. 66 patients represented bimodal pattern CRP graph. Elevation caused by periprosthetic infection were 16,
Background. It is unclear whether the approach of hemiarthroplasty influence the outcomes in elderly patients with displaced femoral neck fractures. We conducted a randomized controlled trial to compare the direct lateral approach (DL approach) and posterolateral approach (PL approach) for hemiarthroplasty. Methods. This study included patients presenting to our hospital with displaced femoral neck fractures (Garden stage 3 or 4) from August 2010 to August 2011. 59 patients agreed the prospective study. They were randomized between the hemiarthroplasty using DL approach or PL approach. We evaluated and compared the operative time, perioperative blood loss, peri- and post-operative complications, and 5-year survival rates. Results. Thirty-two patients underwent the hemiarthroplasty using DL approach and 27 patients underwent hemiarthroplasty using PL approach. The mean operative time was 91 min in DL group and 77 min in PL group. A significant difference was observed for the mean operative times(p<0.005). The bleeding during surgery was 194 g in DL group and 180 g in PL group. The postoperative blood loss was 268 g in DL group and 264 g in PL group, no significant difference was observed postoperatively. Perioperative and postoperative complications were observed in 8 patients of DL group and 5 patients of the PL group. In DL group, perioperative complications included fracture in 1 patient, whereas postoperative complications included
Aim. Aim of this monocentric, prospective study was to evaluate the safety, efficacy, clinical and radiographical results at 24-month follow-up (N = 6 patients) undergoing hip revision surgery with severe acetabular bone defects (Paprosky 2C-3A-3B) using a combination of a novel phase-pure betatricalciumphosphate - collagen 3D matrix with allograft bone chips. Method. Prospective follow-up of 6 consecutive patients, who underwent revision surgery of the acetabular component in presence of massive bone defects between April 2018 and July 2019. Indications for revision included mechanical loosening in 4 cases and history of hip infection in 2 cases. Acetabular deficiencies were evaluated radiographically and CT and classified according to the Paprosky classification. Initial diagnosis of the patients included osteoarthritis (N = 4), a traumatic fracture and a congenital hip dislocation. 5 patients underwent first revision surgery, 1 patient underwent a second revision surgery. Results. All patients were followed-up radiographically with a mean of 25,8 months. No complications were observed direct postoperatively. HHS improved significantly from 23.9 preoperatively to 81.5 at the last follow-up. 5 patients achieved a defined good result, and one patient achieved a fair result. No periprosthetic joint infection, no dislocations, no

Introduction:. Hallux surgery is the most commonly performed elective surgery in the foot and ankle. As with all surgery, there are many potential complications quoted in the literature. Venous thromboembolism (deep vein thrombosis and pulmonary embolism) incidence and prophylaxis, however, is not adequately addressed and remains controversial. Material and Method:. This prospective study includes one hundred patients who underwent hallux surgery. Risk factors implicated to increase the risk of developing venous thromboembolic disease as well as anaesthetic time, thigh tourniquet time and regional anaesthetic blocks were documented. Compressive ultrasonography was performed in all the patients postoperatively to assess for
Introduction. Distal femoral and proximal tibial osteotomies are effective procedures to treat degenerative disease of the knee joint. Previously described techniques advocate the use of bone graft to promote healing at the osteotomy site. In this present study a novel technique which utilises the osteogenic potential of the cambial periosteal layer to promote healing “from the outside in” is described. Materials and Methods. A retrospective analysis of a consecutive single-surgeon series of 23 open wedge osteotomies around the knee was performed. The median age of the patients was 37 years (range 17–51 years). The aetiology of the deformities included primary genu valgum (8/23), fracture malunion (4/23), multiple epiphyseal dysplasia (4/23), genu varum (2/23), hypophosphataemic rickets (1/23), primary osteoarthritis (1/23), inflammatory arthropathy (1/23), post-polio syndrome (1/23), and pseudoachondroplasia (1/23). Results. There were two cases lost to follow-up with a median follow-up period 17 months (range 1–32 months). Union was achieved in all cases, with 1/23 requiring revision for early fixation failure for technical reasons. The median time to radiographic union 3.2 months (95% Confidence Interval (CI) 2.5–3.8 95% CI). CT scans demonstrated early periosteal callus, beneath the osteoperiosteal flap, bridging the opening wedge cortex. Clinical union occurred at 4.1 months (95% CI 3.9–4.2 months). Complications included superficial surgical site infection (1/23),
Introduction. Most Japanese patients who receive total hip arthroplasty (THA) are osteoarthritic and 70% have development dysplasia of the hip. Their stature is shorter than average and their sizes (acetabular cup and femoral stem) are smaller. The Taperloc Microplasty (BIOMET) is a short femoral stem. It was launched on July 2012 in Japan (extended on January 2013). It is essentially a shortened version of the Taperloc stem (35mm shorter than the standard stem). Objectives. We aimed to evaluate the outcomes of minimally invasive anterolateral THA using a short stem. Methods. We retrospectively reviewed all 56 patients who underwent THA at our hospitals between July 2013 and April 2015. Of these 28 (50%) were performed with short stems. The surgical approach was antero-lateral in the lateral position. The patients (4 men and 24 women) had a mean age at surgery of 66.5 years (range, 46–85 years). The original diseases were osteoarthritis (25 patients) and osteonecrosis (3 patients). We investigated the system type, size (cup, femoral head, and stem), radiological findings and complications (fracture, infection,
Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic
Diabetes mellitus is a risk factor for complications after operative management of ankle fractures. Generally, diabetic sequelae such as neuropathy and nephropathy portend greater risk; however, the degree of risk resulting from these patient factors is poorly defined. We sought to evaluate the effects of the diabetic sequelae of neuropathy, chronic kidney disease (CKD), and peripheral vascular disease (PVD) on the risk of complications following operative management of ankle fractures. Using a national claims-based database we analyzed patients who had undergone operative management of an ankle fracture and who remained active in the database for at least two years thereafter. Patients were divided into two cohorts, those with a diagnosis of diabetes and those without. Each cohort was further stratified into five groups: neuropathy, CKD, PVD, multiple sequelae, and no sequelae. The multiple sequelae group included patients with more than one of the three sequelae of interest: CKD, PVD and neuropathy. Postoperative complications were queried for two years following surgery. The main complications of interested were:
Introduction. The use of intramedullary lengthening devices is becoming increasingly popular. There are no published data regarding the incidence of venous thromboembolism following intramedullary lengthening and no reports or guidance for current practices on use of thromboprophylaxis. Following a case of post-operative
To evaluate the short-term clinical outcomes of patients treated arthroscopically with chitin-based scaffolding for acetabular chondral defects in conjunction with microfracture compared to microfracture alone. This study is a retrospective analysis of prospectively collected data. A review of charts was performed (2014–2016) on all patients who underwent hip arthroscopy and had microfracture +/− scaffolding for acetabular chondral defects, intraoperative details (lesion size, grade, labral repair/reconstruction) and postoperative complications were recorded with a minimum follow-up of 2 years. Clinical outcomes were assessed by analysing iHOT and HOS scores which were obtained pre-operatively, at six months, one year and two years post-surgery. Plain radiographs were assessed for hip osteoarthritis by Kellgren & Lawrence grading. A total of 60 patients (microfracture=25, scaffolding=35) were included. Patients had a mean age of 36.2 years at the time of the index operation. There were no major adverse events of deep vein 36.2 years at the time of the index operation. There were no major adverse events of
Informed consent is vital for good patient-surgeon communication. It allows the patient to be given an unbiased and accurate view of the procedure as well giving an opportunity for patients to gain trust in their surgical team. The consent form is written evidence of this discussion and a poor consent form implies a sub-standard consenting process. The General Medical Council (GMC) have issued guidelines for consent in surgical procedures. These state that all common risks and rare but serious risks should be disclosed as well as all information being given in clear simple and consistent language. Currently, the consent form for a hip fracture operation is hand written. Our hypothesis was that the quality of consenting is variable and that many important complications may not be identified. The British Orthopaedic Association (BOA) blue book, ‘The care of patients with fragility fractures,’ has given guidance of common and serious complications associated with operative management of hip fractures. In addition to these procedure specific complications, we have identified general complications from standardised joint arthroplasty consent forms in our trust, such as
Venous thromboembolism (VTE) is a serious complication after total hip and knee arthroplasty. There is still no consensus regarding the best mode of thromboprophylaxis after lower limb arthroplasty. The aim of this study was to ascertain the efficacy, safety profile and rate of adverse thromboembolic events of aspirin as extended out of hospital pharmacological anticoagulation for elective primary total hip and knee arthroplasty patients and whether these rates were comparable with published data for low molecular weight heparin (LMWH). Data was extracted from a prospective hospital acquired thromboembolism (HAT) database. The period of study was from 1st Jan 2013-31st Dec 2016 and a total of 6078 patients were treated with aspirin as extended thromboprophylaxis after primary total hip and knee arthroplasty. The primary outcome measure of
