Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this

Tranexamic Acid (TXA) is widely used to decrease bleeding by its antifibrinolytic mechanism. Its use is widespread within orthopaedic surgery, with level one evidence for its efficacy in total hip and knee replacement surgery; significantly reducing transfusion rates without increased thromboembolic disease. There is limited evidence for its use during hip fracture surgery, and we therefore sought to investigate its effects with a
Introduction. Periprosthetic joint infection (PJI) is a serious problem and requires great effort and cost for its treatment. Treatment options may vary from resection arthroplasty, retention of prosthesis with debridement, one stage revision and two stage revision with handmade antibiotic impregnated cement spacer or with prefabricated antibiotic loaded cement spacer. Two stage revision remains the gold standard for the treatment of periprosthetic joint infection after Total Hip Arthroplasty (THA). This study was aimed to find the efficacy and cost effectiveness of handmade antibiotic impregnated articulating cement spacer over commercially available prefabricated antibiotic loaded cement spacer for the treatment of deep PJI of hip prosthesis and to evaluate its functional outcome. Material and methods. A total of 23 PJI patients were enrolled in this
Aim. Current guidelines recommend the combination of vancomycin with either piperacillin-tazobactam (PT) or a third generation cephalosporin (3GC) as empirical antimicrobial therapy of PJI, immediately after surgery. However, clinical and biological safeties of such high dose-combinations are poorly known. Method. All patients managed in a reference center in France between 2011 and 2016 receiving an empirical antimicrobial therapy for PJI were included in a
Malnutrition is often associated with the advanced age and can be influenced by physical, mental, social and environmental changes. Hip fracture is a major issue and a prior poor nutritional status is associated with higher rates of perioperative complications and prolonged hospital length of stay.
Background. Periprosthetic joint infection (PJI) remains challenging as a “gold standard” for diagnosis has not yet been established. The aim of this study was to evaluate the accuracy of synovial fluid procalcitonin (SF-PCT) and serum procalcitonin as diagnostic biomarker for PJI and compared their accuracy with standard methods. Materials and Methods. A single-centered
Introduction and Objective. Hip fractures represent one of the most challenging injuries in orthopaedic practice due to the associated morbidity, mortality and the financial burden they impose on the health care systems. By many still considered as the gold standard in the management of intertrochanteric fractures, the Dynamic Hip Screw utilizes controlled collapse during weight bearing to stabilize the fracture. Despite being a highly successful device, mechanical failure rate is not uncommon. The most accepted intraoperative indicator for lag screw failure is the tip apex distance (TAD), yet lateral femoral wall thickness (LWT) is another evolving parameter for detecting the potential for lateral wall fracture with subsequent medialization and implant failure. The aim of this study is to determine the mean and cut off levels for LWT that warrant lateral wall fracture and the implications of that on implant failure, revision rates and implant choice. Materials and Methods. This
Recent technological advancements have led to the introduction of robotic-assisted total knee arthroplasty to improve the accuracy and precision of bony resections and implant position. However, the in vivo accuracy is not widely reported. The primary objective of this study is to determine the accuracy and precision of a cut block positioning robotic arm. Seventy-seven patients underwent total knee arthroplasty with various workflows and alignment targets by three arthroplasty-trained surgeons with previous experience using the ROSA® Knee System. Accuracy and precision were determined by measuring the difference between various workflow time points, including the final pre-operative plan, validated resection angle, and post-operative radiographs. The mean difference between the measurements determined accuracy, and the standard deviation represented precision.Introduction
Method
Previously ankylosed or surgically arthrodesed hip joints can be converted successfully to a total hip replacement (THR) in order to improve patient mobility and function. We present a long term
Summary Statement. Service industry metrics (the net promoter score) are being introduced as a measure of UK healthcare satisfaction. Lower limb arthroplasty, as a ‘service’, scores comparably with the most successful commercial organisations. Background. Satisfaction with care is important to both the patient and the payer. The Net Promoter Score, widely used in the service industry, has been recently introduced to the UK National Health Service as an overarching metric of patient satisfaction and to monitor performance. This questionnaire asks ‘customers’ if they would recommend a service or products to others. Scores range from −100 (everyone is a detractor) to +100 (everyone is a promoter). In industry, a positive score is well regarded, with those over 50 regarded as excellent. Our aims were to assess net promoter scores for joint arthroplasty, to compare these scores with direct measures of patient satisfaction, and to evaluate which factors contributed to net promoter response. Methods. 6912 individuals undergoing primary lower limb joint replacement over a five year period (Jan 2007 – Dec 2011) took part in a
Purpose: Comorbidities in patients undergoing total joint arthroplasty continue to be a challenging problem. Retrospective studies have demonstrated that co-morbidities affect outcomes of revision total knee arthroplasty (RTKA). However, the relationship between the outcomes of RTKA and co-morbidities has not been well established. This prospective randomized study was undertaken to investigate these relationships. Method: A
The use of total hip arthroplasty in adolescents for end-stage degenerative hip disease is controversial with few reported outcomes in the literature. The purpose of the study was to report the outcomes of total hip arthroplasty in a cohort of adolescents managed by a multidisciplinary team of paediatric and adult orthopaedic surgeons from a single centre. A multidisciplinary clinic consisting of paediatric and adult hip surgeons was established in 2013 to identify, treat and prospectively follow adolescents who would potentially beneift from a total hip arthoplasty. To date 29 consecutive adolescent patients (20 female, 9 male, 32 hips) with end stage degenerative hip disease have undergone cementless primary total hip arthroplasty. Mean age at decision to treat was 15.7 years (age 11.4–18.5). Ten different underlying paediatric specific pathologies were documented including DDH, cerebral palsy, JIA, skeletal dysplasias, SCFE and idiopathic chondrolysis. Three patients had bilateral staged procedures. Clinical baseline and outcomes were measured using Oxford Hip Score (OHS), WOMAC score and ASKp scores. Radiographic follow-up was conducted at 6 weeks, 6 months and yearly thereafter. Post-operative complications were recorded. Twenty-five hips were eligible for minimum 2-year follow-up scoring at a mean 2.7 years (2.0–3.6 years). No intraoperative complications occurred. One case of recalcitrant postoperative psoas tendonitis occured. OHS improved from 25 (7–43) to 41 (23–48). WOMAC improved from 48 (12–8) to 12 (1–44), and ASKp improved from 78% (33–98%) to 93% (73–100%). Radiographic review revealed acceptable alignment of all components with no signs of loosening or wear. No revision of components was required. One patient died at 6 months post op from an unrelated condition. The early term results of total hip arthroplasty in adolescents from our multidisciplinary program are encouraging. Improvements in quality of life to normal values were seen as were hip scores consistent with satisfactory joint function. Depite the range of complex and varied causes of arthritis seen in this population the establishment of combined paediatric and adult orthopaedic surgical teams appears to be a successful model to manage end-stage degenerative hip disease in adolescents.
Study purpose: Cancer patients presenting with symptomatic spinal metastases is an increasing problem. It is widely accepted that surgery plays an important role in the management of these patients and recent studies1 conclude that surgical treatment should be more frequently offered. However, who should be offered surgery remains controversial, largely because of a lack of information about outcome. Our study is a prospective analysis of survival and functional outcome in patients with metastatic spinal disease treated primarily by surgical decompression and stabilisation when indicated. Methods: Sixty two patients with radiologically suspected metastatic spinal disease, managed by one consultant neurosurgeon, were enrolled into a
Whilst short and mid-term activity levels after a Total Knee Replacement (TKR) have been reported in the literature; there is an over simplification of the reporting and longer-term activity levels are unknown. The aim of this study was to map the long-term trajectories of patients’ physical activity levels postoperatively to identify meaningful subgroups and explore associations with preoperative variables. This was a secondary analysis of a single centre longitudinal cohortstudy using group-based trajectory modelling (GBTM) of the University of California, Los Angeles (UCLA) physical activity score over ten years. Multinomial logistic regression models (both adjusted and unadjusted) were used to test associations between preoperative variables and trajectory group membership.Abstract
Aims
Methods
Low back pain can lead to neuroplastic changes in the central nervous system, known as nociplastic pain. As nociplastic pain may be provoked by premorbid sensory profiles, such profiles may be prognostic in the development of nociplastic pain over time. To investigate whether four sensory profiles are prognostic in the development of symptoms of nociplastic pain in people with acute low back pain.Background
Objectives
Robotic assisted surgery aims to reduce surgical errors in implant positioning and better restore native hip biomechanics compared to conventional techniques for total hip arthroplasty (THA). The primary objective of this study was to compare accuracy in restoring the native centre of hip rotation in patients undergoing conventional manual THA versus robotic-arm assisted THA. Secondary objectives were to determine differences between these treatment techniques for THA in achieving the planned combined offset, cup inclination, cup version, and leg-length correction. This
Aims: To explore potential predictors of functional outcome one year after the injury in elderly women who sustained a displaced intracapsular hip fracture and who were treated with internal fixation, hemiarthroplasty, or total hip arthroplasty. Methods: Eighty-four women aged >
50 years were enrolled on a consecutive basis in this one-year
Introduction: Lumbar spinal stenosis commonly affects elderly patients with multiple co-morbidities. They are at increased risk of complications following surgical interventions. Non-operative strategies for treating them are desirable and previous studies have shown some benefit of subcutaneous salmon calcitonin for the treatment of spinal stenosis. Objectives: To assess the effectiveness of nasal salmon calcitonin for the treatment of lumbar spinal stenosis in a cohort of patients. Study design:
With recent progress in cancer treatment, the number of advanced-age patients with spinal metastases has been increasing. It is important to clarify the influence of advanced age on outcomes following surgery for spinal metastases, especially with a focus on subjective health state values. We prospectively analyzed 101 patients with spinal metastases who underwent palliative surgery from 2013 to 2016. These patients were divided into two groups based on age (< 70 years and ≥ 70 years). The Eastern Cooperative Oncology Group (ECOG) performance status (PS), Barthel index (BI), and EuroQol-5 dimension (EQ-5D) score were assessed at study enrolment and at one, three, and six months after surgery. The survival times and complications were also collected.Aims
