weight bearing versus non weight bearing

INTRODUCTION: Fragility fractures are a large source of morbidity and mortality in the elderly. Orthopaedic surgeons are regularly the main point of contact in patients with lateral compression type 1 pelvis fractures, despite many of these being treated non-operatively. This study aims to identify risk factors for mortality and elucidate which follow-up visits have the potential to improve care for these patients. METHODS AND MATERIALS: In all, 211 patients have been identified with fragility lateral compression type 1 fractures at a level 1 trauma centre over a 5-year period...

BACKGROUND: Instrument assisted soft tissue mobilization and foam rolling are two techniques that have been proven effective in treating Myofascial Trigger Points, irrespective of the type of trigger point. However, little is known about the comparative effectiveness of Instrument assisted soft tissue mobilization and foam rolling. This study proposed to evaluate the effectiveness of either technique on plantar flexors trigger points, ankle dorsiflexion, and lower limb power present in the calf muscles in non-symptomatic patients...

BACKGROUND: Constructing an osseointegrated prosthetic leg is the necessary subsequent phase of care for patients following the surgical implantation of an osseointegrated prosthetic limb anchor. The surgeon implants the bone-anchored transcutaneous implant1,2 and the prosthetist constructs the prosthetic leg, which then attaches to the surgically implanted anchor. An osseointegration surgical procedure is usually considered in patients who are unable to use or are dissatisfied with the use of a socket prosthesis...

BACKGROUND: Morton's neuroma (MN) is a painful neuropathy resulting from a benign enlargement of the common plantar digital nerve that occurs commonly in the third webspace and, less often, in the second webspace of the foot. Symptoms include burning or shooting pain in the webspace that extends to the toes, or the sensation of walking on a pebble. These impact on weight-bearing activities and quality of life. OBJECTIVES: To assess the benefits and harms of interventions for MN...

Soil stabilisation by waste materials has been recently employed to enhance soil engineering properties. The purpose of this study is to compare the impact of utilising sawdust in its raw form versus sawdust ash as a soil stabiliser. This is to determine if sawdust (SD) can be considered as a substitute for sawdust ash (SDA) in order to reduce incineration and air pollution. To fulfil this aim, the Atterberg limits, modified Proctor test, and Direct Shear test were performed on both stabilised and non-stabilised mixtures of clayey soil...

BACKGROUND: Few studies have evaluated the effects of symmetrical versus asymmetrical implant designs, more specifically the femoral condyles, trochlear groove, joint line, and bearing surfaces. The objective of this study is to investigate multiple posterior cruciate-retaining (PCR) total knee arthroplasty (TKA) designs influencing factors related to TKA asymmetry, and whether asymmetry can improve postoperative knee kinematics. METHODS: In vivo tibio-femoral kinematics for 99 subjects were evaluated in this retrospective study...

OBJECTIVE: To propose a protocol for assessing knee instability in ACL-injured knees using weight-bearing computed tomography (WBCT). MATERIALS AND METHODS: We enrolled five patients with unilateral chronic ACL tears referred for WBCT. Bilateral images were obtained in four positions: bilateral knee extension, bilateral knee flexion, single-leg stance with knee flexion and external rotation, and single-leg stance with knee flexion and internal rotation. The radiation dose, time for protocol acquisition, and patients' tolerance of the procedure were recorded...

BACKGROUND: Persistent anterior knee pain post total knee arthroplasty (TKA) is a significant cause of patient dissatisfaction. Selective patellar resurfacing is commonly practiced for primary total knee replacement (TKR) but there is a paucity in literature regarding its decision making. STUDY OBJECTIVE: This study aims to develop a decision-making algorithm for selective patellar resurfacing using Hospital for Special Surgery Patello-femoral Assessment score (HSS PFA score), weight-bearing patellofemoral X-ray, and intraoperative cartilage wear assessment based on the Outerbridge classification...

BACKGROUND: Patient factors are known to contribute to decision making and treatment of ankle fractures. The presence of poor baseline mobility, diabetes, neuropathy, alcoholism, cognitive impairment, inflammatory arthritis or polytrauma can result in a higher risk of failure or complications. Limited evidence is available on the optimum management for this challenging cohort of patients herein described as complex ankle fractures. This UK multicentre study assessed and evaluated the epidemiology of ankle fractures complicated by significant comorbidity and patient factors and use of specialist surgical techniques such as hindfoot nails (HFN) / tibiotalarcalcaneal (TCC) nails and enhanced open reduction and internal fixation (ORIF)...

BACKGROUND: Constrained inserts in total knee arthroplasty (TKA) may offer additional stability, but can this insert type allow unrestricted movements or will the extra conformity cause kinematic conflict with the cam/post mechanism in deeper flexion? The objective of this study was to evaluate the weight-bearing kinematics of both traditional and constrained Bi-Cruciate Stabilized (BCS) TKA inserts to determine if the rollback induced by the cam/post mechanism will work in unison with the constrained polyethylene insert...

PURPOSE: Intensified acute in-hospital physiotherapy (IP) after hip fracture (HF) may enhance patient's ability to regain basic mobility at discharge. The primary objective was to assess the feasibility of IP. Secondary to estimate the effect of IP on regained basic mobility at discharge. MATERIALS AND METHODS: In a pragmatic, randomized, unblinded feasibility trial, 60 patients (mean age 79 years, 41 women) with HF and an independent pre-fracture basic mobility level were randomized (2:1) to IP with two daily sessions on weekdays focusing on functional training and weight-bearing activities ( n  = 40) versus usual care (UC) physiotherapy once daily ( n  = 20)...

BACKGROUND: Several methods have been used to treat pediatric Jones fractures, but there has been no consensus about the optimum method. The purposes of this study were to compare the clinical outcomes between compression screw and non-weight-bearing techniques used in pediatric Jones fractures and clarify the most suitable treatment option for this population. METHODS: Twenty-one patients who presented with Jones fractures between January 2015 and June 2021 were analyzed retrospectively...

PURPOSE: Ulnar variance (UV) is a radiographic measurement relating the articular surface heights of the distal radius and ulna. Abnormal UV increases the risk for wrist pathology; however, it only provides a static measurement of an inherently dynamic bony relationship that changes with wrist position and loading. The purpose of this study was to investigate how full-body weight-bearing affects UV using weight-bearing computed tomography (WBCT). METHODS: Ten gymnasts completed two 45-second scans inside a WBCT machine while performing a handstand on a flat platform (H) and parallettes (P)...

The Achilles tendon has a high incidence of ruptures often occurring in weekend warriors and the aging population. Based on anatomic studies of the Achilles tendon, ruptures are commonly found in the watershed area proximal to the insertion site. Traditionally, treatment options included conservative therapy with immobilization and a prolonged non-weight-bearing phase versus surgical treatment. Surgical treatment can vary between open, minimally invasive, or percutaneous approaches. In more recent years, early functional rehabilitation with or without surgery has shown to have successful results...

BACKGROUND: Accumulating evidence links the echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement to venous thromboembolism (VTE) in non-small cell lung cancer (NSCLC) patients. However, the corresponding mechanisms remain unclear. METHOD: High-throughput sequencing analysis of H3122 human ALK-positive NSCLC cells treated with ALK inhibitor/ dimethyl sulfoxide (DMSO) was performed to identify coagulation-associated differential genes between EML4-ALK fusion protein inhibited cells and control cells...

From the perspective of energy expenditure, this study investigated the effects of whole-body vibration training on the energy metabolism of deep squats with different weights. Twenty-two healthy male college students with sports experiences were selected and randomly assigned to perform resistance exercise vibration (REV) or resistance exercise (RE) with varying loads two times per week for 4 weeks. Oxygen uptake and heart rate were measured before, during, and after exercises using a gas analyzer, and energy expenditure was calculated...

PURPOSE: Acromioclavicular joint (ACJ) dislocations are usually graded radiographically according to Rockwood, but differentiation between Rockwood types III and V may be ambiguous. The potentially clinically relevant horizontal instability is barely addressed in coronal radiographs. It was hypothesized that a new radiologic parameter (V angle) would complement ACJ diagnostics on anteroposterior radiographs by differentiating between cases of Rockwood III and V while also considering the aspect of dynamic horizontal translation (DHT)...

Background and objective The coronavirus disease 2019 (COVID-19) pandemic necessitated a sudden and drastic shift in patient management throughout the healthcare system, to curb the spread of the disease and deal with resource limitations. Many surgical cases were canceled or delayed with only the most urgent and emergent cases taken up for treatment. It is unknown if and how these alterations affected patient outcomes. The purpose of this study was to compare time to fracture care and outcomes between patients treated for humeral shaft fractures prior to the COVID-19 pandemic and those treated during the pandemic...
