Introduction. In patients with shoulder pain one of the important initial determinations is to assess the integrity of the rotator cuff. Clinical examination is often inconclusive. Compared with MRI and arthrography, ultrasound allows dynamic evaluation, is non-invasive, less expensive, less time-consuming and more acceptable to patients. The aim of the present study was to evaluate the accuracy of high resolution shoulder
Total knee arthroplasty (TKA) is one of the most successful surgeries to relieve pain and dysfunction caused by severe arthritis of the knee. Despite developments in prophylactic methods, deep venous thrombosis (DVT) and pulmonary embolism (PE) continue to be a serious complication following TKA. Otherwise DVT/PE is known to be a relatively low incidence in Asian patients, its accurate incidence is still controversial. Therefore, we prospectively investigated the incidence of DVT/PE after primary TKA by contrast enhanced computed tomography (CE-CT) and venous
Musculoskeletal ultrasound (MSK-US) can have many uses for orthopaedic surgeons, such as assisting in clinical diagnosis for muscle, tendon and ligament injuries, providing direct guidance for joint injections, or assessing the adequacy of a reduction in the emergency department. However, proficiency in sonography is not a requirement for Royal College certification, and orthopaedic trainees are rarely exposed to this modality. The purpose of this project was to assess the usefulness in clinical education of a newly implemented MSK-US course in an orthopaedic surgery program. A MSK-US course for orthopaedic surgery residents was developed by an interdisciplinary team involving a paediatric orthopaedic surgeon, an emergency physician with a fellowship in point-of-care
Introduction. Pulmonary emboli (PE) after total hip and knee arthroplasties is an uncommon event. However, once it happens, it may results in sudden death. Thus, the prophylaxis of venous thromboembolism (VTE), including symptomatic deep vein thrombosis (DVT) and PE, is one of the challenging trials for Orthopaedic surgeons. Many procedures have been developed, e.g. early mobilization, compression stocking, intermittent pneumatic compression (IPC) devices, and anticoagulation agents. However, the most effective treatment for prophylaxis against VTE after the arthroplasties remains undecided. Recently, many low molecular weight heparin (LMWH) agents are developing, and these are strongly effective for anticoagulation. However, these agents sometimes lead to bleeding complications, and result in uncontrolled critical bleeding. We are introducing our protocol with conventional aspirin as VTE prophylaxis after the arithroplasties. Patients and methods. All patients prior to the surgeries are evaluated laboratory and duplex venous
Introduction. Total knee arthroplasty (TKA) is one of the most successful surgeries to relieve pain and dysfunction caused by severe arthritis. However, it is a still big problem that there is a possibility of death in pulmonary embolism (PE) after TKA. We previously reported that there was more incidence of asymptomatic PE than estimated in general by detail examinations. But it was difficult to whom we decided to perform additional examinations except the patients with some doubtful symptoms. Therefore, we investigated detail of PE patients after primary TKA to find out anything key point in PE. Methods. Consecutive ninety-nine patients who underwent primary TKA from January 2015 to March 2018 were applied. There were 23 male and 76 females included, and the mean age was 73.7 years old. There were 96 cases of osteoarthritis, 2 cases of osteonecrosis and one of rheumatoid arthritis. A single knee surgery team performed all operations with cemented type prostheses and air tourniquet during operation. There were 35 cases of one-staged bilateral TKA and 64 of unilateral TKA. Detail examinations with contrast enhanced CT (CE-CT) and venous
Introduction. Patients undergoing total hip arthroplasty (THA) stand in the danger, a particularly high risk for venous thromboembolism (VTE). Fondaparinux and edoxaban, which inhibit FXa, indirectly and directly, respectively, have been used for prevention of VTE after THA in Japan. The aim of this study was to compare the efficacy of fondaparinux and edoxaban for VTE after elective THA in Japanese patients. Materials and methods. We randomly assigned 320 patients underdoing elective cemented THA to receive postoperative 2.5 mg fondaparinux once daily for first postoperative 3 days and 1.5 mg once daily for the subsequent 7 days (FPX group) [1], postoperative 15 mg edoxaban once daily for postoperative 10 days (EDO15mg group), 30 mg edoxaban once daily for postoperative 10 days (EDO30mg group), and 30 mg edoxaban once daily for first postoperative 3 days and 15 mg once daily for the subsequent 7 days (EDOmix group). Deep venous thrombosis (DVT) was diagnosed by
A prospective, randomized, double-blind study was done on 50 patients undergoing primary cementless total hip arthroplasty to determine the effect of tranexamic acid on intra- and postoperative blood losses and on the transfusions requirements. 50 patients were randomized to tranexamic acid (15 mg/kg) given as a bolus intravenous injection or placebo (normal saline) given intravenously, 15 minutes before the incision. The intraoperative and postoperative blood loss (at removal of the drain 24 hours after the operation) and the number of blood transfusions required were recorded. The patients were screened for deep venous thrombosis with bilateral compression

Thromboembolic disease (TED) remains as a major concern for orthopaedic surgeons and is a well-known complication of lower extremity joint replacement procedures. While there is voluminous literature on the topic, it is difficult for the average orthopaedic surgeon to keep up with all the advancements in this area as well as the newer pharmacological options for prophylaxis. To address this, the American Academy of Orthopaedic Surgeons (AAOS) has developed a clinical practice guideline (CPG) in this area to provide treatment recommendations based on the best available evidence. Historically, guidelines for TED prophylaxis have been based largely on randomised controlled trials whose outcome measure was venographically documented deep vein thrombosis (DVT). However, many venographically documented DVTs, particularly those distal to the popliteal vein, are of no clinical consequence. Therefore, in the AAOS CPG the systematic review of the literature was focused on those outcomes that have the most clinical relevance: all-cause mortality, symptomatic or fatal pulmonary embolism (PE), proximal DVT, major bleeding and symptomatic DVT rates. Using these as the clinically important endpoints, it is evident that the extant literature is insufficient to provide definitive guidance in this area and to make specific recommendations about optimal pharmacological prophylaxis. Nonetheless, one strong recommendation has emerged from this systematic review: the guideline recommended against routine post-operative duplex
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
Our study is still in progress. The results mentioned in the abstract are preliminary results. The final results will be provided at the time of presentation. Over the past decade, the widespread availability of high-resolution
Background/Purpose. Total hip arthroplasties (THAs) with ceramic bearings are widely performed in young, active patients and thus, long-term outcome in these population is important. Moreover, clinical implication of noise, in which most studies focused on ‘squeaking’, remains controversial and one of concerns unsolved associated with the use of ceramic bearings. However, there is little literature regarding the long-term outcomes after THAs using these contemporary ceramic bearings in young patients. Therefore, we performed a long-term study with a minimum follow-up of . 1. 5 years after THAs using contemporary ceramic bearings in young patients with osteonecrosis of the femoral head (ONFH) less than fifty. Materials and Methods. Among sixty patients (71 hips) with a mean age of 39.1 years, 7 patients (7 hips) died and 4 patients (4 hips) were lost before 15-year follow-up. The remaining 60 hips were included in this study with an average follow-up period of 16.3 years (range, 15 to 18). All patients underwent cementless THA using a prosthesis of identical design and a 28-mm third-generation alumina head by single surgeon. The clinical evaluations included the modified Harris hip score (HHS), history of dislocation and noise around the hip joint: Noise was classified into squeaking, clicking, grinding and popping and evaluated at each follow-up. Snapping was excluded through physical examination or
Venous thromboembolic events, either deep vein thromboses or pulmonary emboli, are important complications in patients undergoing knee or hip arthroplasty. The purpose of this study was to evaluate the effectiveness of a mobile compression device (ActiveCare+S.F.T.®; Medical Compression Systems, Inc., Or Akiva, Israel) with or without aspirin compared with current pharmacology protocols for venous thromboembolism prophylaxis in patients undergoing elective primary unilateral lower extremity joint arthroplasty. A multicenter registry was established to capture the rate of symptomatic venous thromboemboli following primary lower extremity joint arthroplasty in 3,060 patients from ten sites including knee arthroplasty (1,551) or hip arthroplasty (1,509). All patients were 18 years of age or older with no known history of venous thromboembolism, coagulation disorder, or solid tumor. Use of the compression device began peri-operatively and continued for a minimum of ten days. Patients with symptoms of deep venous thrombosis or pulmonary embolism underwent duplex
Objective. The purpose of this study was to evaluate the efficacy and safety of the drained-clamped method with intra-articular infusion of tranexamic acid (TA) for reducing blood loss in total knee arthroplasty (TKA). Material and Methods. From November 2011 to July 2014 inclusive, 72 patients with a diagnosis of osteoarthritis underwent unilateral primary TKA using a computed tomography (CT) free navigation system. Patients were randomly divided into two groups: group T (n=40) was given 2000 mg (40 ml) of TA and group W (n=32) was given 40 ml sterile saline only. All operations were performed under total anaesthesia through the medial mid-vastus approach. Cemented posterior stabilised or cruciate retaining prostheses were used. The patella was resurfaced. After tourniquet release and wound suture, TA or saline was infused into the knee joint in addition to the drained-clamped method for 2 hours. For VTE prophylaxis, all patients received bilateral intermittent pneumatic calf compressors, thromboembolic deterrent stockings, and subcutaneous injection of enoxaparin (4000IU daily). We evaluated the hematocrit, hemoglobin and the postoperative estimate of bleeding. At postoperative days 4, extremity venous
Background. Theoretically, improved material properties of new alumina matrix composite (AMC) material, Delta ceramics, are expected to decrease concerns associated with pure alumina ceramics and allow manufacturing thinner liners and consequent larger heads. However, limited short-term clinical results are available and mid-term results of these effects are unclear. Questions/Purposes. (1) Does AMC material decrease the rate of ceramic fracture and noise, concerns of previous-generation ceramics, following change of material properties? (2) Does the possible use of larger heads consequent to manufacturing thinner liners decrease dislocation rate and affect inguinal pain? (3) Do any other complications associated with the use of AMC ceramics occur?. Materials and Methods. One-hundred cementless primary total hip arthroplasties (THAs) using AMC ceramic bearings were performed consecutively by single surgeon. The mean follow-up period was 5.4 years (range, 5.0 to 5.7) and average age at the time of arthroplasty was 54.7 years. Prostheses with identical design and Biolox® Delta ceramics were used in all patients. Clinical evaluation included the occurrence of inguinal pain and noise which was classified into squeaking, clicking, grinding and popping. Ceramic fracture, dislocation and any other complications associated with the use of AMC ceramics were also investigated. Result. No ceramic fracture occurred and noise was reported in three patients (3.2%); three subjective clicking, but no squeaking. Single event of perioperative dislocation due to incompliance occurred in one hip (1.1%) and inguinal pain was reported in two hips (2.1 %); neither evidence of iliopsoas tendinitis on

INTRODUCTION. Venous thromboembolism (VTE), especially, deep vein thrombosis (DVT) in lower extremities, often seriously combined with pulmonary embolism (PE), is a major and critical complication after total hip arthroplasty (THA). For better disgonsis of VTEs, D-dimer test is one of the useful methods. The aim of this study was to evaluate the efficacy of D-dimer levels before THA. MATERIALS AND METHODS. Medical records of patients with osteoarthritis who received THA between April 2009 and March 2010 were reviewed. Value of D-dimer at preoperative day 1, postoperative day 3 and 14 was examined in those patients. D-dimer levels were examined by Latex Immunity Nephelometry Measurement Method and the Kit (Sysmex Corporation, Kobe, Japan). A total of 327 patients with D-dimer values were examined. The values D-dimer of the available patients were under 1.0 μg/ml. Ninety-nine patients (30%) had a high D-dimer level. DVT was diagnosed by doppler
Estrogen fluctuations have been implicated in the soft tissue injury gender-bias due to the hormones effect on the viscoelastic properties. The isolated effect of estrogen on the mechanical behaviour of human tendon is unknown. The purpose of this study was to elucidate the effect of circulating levels of estrogen on the strain properties of the human Achilles tendon. Twenty females (18–35 years) who were using the pill together with 20 matched, non-pill users, participated in this study. Non-pill users were tested at the time of lowest (menstruation) and highest (ovulation) estrogen whilst pill users, who exhibited constant and attenuated estrogen levels, were tested at menstruation and two weeks later. At each test session, maximal isometric plantarflexion efforts were performed on a calf-raise apparatus whilst synchronous real-time
