Creating an Implementation Enhancement Plan for a Digital Patient Fall Prevention Platform Using the CFIR-ERIC Approach: A Qualitative Study.

(1) Background: Inpatient falls are a major cause of hospital-acquired complications (HAC) and inpatient harm. Interventions to prevent falls exist, but it is unclear which are most effective and what implementation strategies best support their use. This study uses existing implementation theory to develop an implementation enhancement plan to improve the uptake of a digital fall prevention workflow.

Conservative, minimally invasive and open surgical repair for management of acute ruptures of the Achilles tendon: a clinical and functional retrospective study.

Background: At present, it is unclear which is the best management for Achilles tendon rupture.

Purpose: We assess the clinical, functional and imaging outcomes of active patients undergoing 3 different types of management for acute subcutaneous rupture of the Achilles tendon, including conservative cast immobilization, traditional open surgery and percutaneous repair.

Methods: 26 active patients were managed for a rupture of the Achilles Tendon from January 2007 to March 2008.

Diagnostic performance of volume and limited oblique MRI of the anterior cruciate ligament compared to knee arthroscopy.

Background: Many strategies have been used to improve the visualisation of the ACL including sagittal, coronal oblique sequences, and 3D volume imaging. Nevertheless, the ACL may not always be visualised.

Methods: Two hundred and thirty-one consecutive patients (77 females; 154 males; average age 43.

Autonomous magnetic labelling of functional mesenchymal stem cells for improved traceability and spatial control in cell therapy applications.

Mesenchymal stem cells (MSCs) represent a valuable resource for regenerative medicine treatments for orthopaedic repair and beyond. Following developments in isolation, expansion and differentiation protocols, efforts to promote clinical translation of emerging cellular strategies now seek to improve cell delivery and targeting. This study shows efficient live MSC labelling using silica-coated magnetic particles (MPs), which enables 3D tracking and guidance of stem cells.

Purpose: The purpose of this study was to evaluate the relation between pelvic fracture patterns and the angiographic findings, and to assess the effectiveness of the embolisation.

Methods: This retrospective study, included patients with pelvic fractures and angiographic evaluation. Demographics, Injury Severity Score (ISS), associated injuries, embolisation time, blood units needed, method of treatment and complications were recorded and analysed.

Mechanical correction of dynamometer moment for the effects of segment motion during isometric knee-extension tests.

The purpose of this study was to determine the effect of dynamometer and joint axis misalignment on measured isometric knee-extension moments using inverse dynamics based on the actual joint kinematic information derived from the real-time X-ray video and to compare the errors when the moments were calculated using measurements from external anatomical surface markers or obtained from the isokinetic dynamometer. Six healthy males participated in this study. They performed isometric contractions at 90° and 20° of knee flexion, gradually increasing to maximum effort.

Spine computed tomography doses and cancer induction.

Study Design: Computer modeling using patient computed tomography (CT) exposure data.

Objective: To adequately consent patients, radiation dose needs to be converted into a relative risk of inducing a cancer. This article estimates different radiation doses and their relative risk of inducing a cancer from spine CT.

Correction and prevention of deformity in type II tibialis posterior dysfunction.

Unlabelled: Cobb described a method of reconstruction in Johnson and Strom Type II tibialis posterior dysfunction (TPD) using a split tibialis anterior musculotendinous graft. We assessed patient function and satisfaction after a modified Cobb reconstruction in a group of patients with a narrow spectrum of dysfunction, examined a modification of the Johnson and Strom classification to emphasize severity of deformity, and assessed the ability of the technique to prevent subsequent fixed deformity. We prospectively followed 32 patients managed by this technique and a translational os calcis osteotomy with early flexible deformity after failed conservative treatment.

Magnetic resonance imaging, knee arthroscopy, and clinical decision making: a descriptive study of five surgeons.

Objectives: A randomized controlled trial (RCT) showed magnetic resonance imaging for patients waiting for knee arthroscopy did not reduce the number of arthroscopies. Our study aimed to identify decisions made by orthopedic surgeons about whether patients on a waiting list should proceed to arthroscopy, and to describe surgeons' decisions.

Methods: Five surgeons were asked to Think Aloud (TA) as they made their decisions for twelve patients from the original RCT.

Longitudinal microvascularity in Achilles tendinopathy (power Doppler ultrasound, magnetic resonance imaging time-intensity curves and the Victorian Institute of Sport Assessment-Achilles questionnaire): a pilot study.

Aim: To evaluate the imaging of the natural history of Achilles tendinopathy microvascularisation in comparison with symptoms, using a validated disease-specific questionnaire [the Victorian Institute of Sport Assessment-Achilles (VISA-A)].

Method: A longitudinal prospective pilot study of nine patients with post-contrast magnetic resonance imaging (MRI), time-intensity curve (TIC) enhancement, ultrasound (US) and power Doppler (PD) evaluation of tendinopathy of the mid-Achilles tendon undergoing conservative management (eccentric exercise) over 1 year.

Results: There were five men and four women [mean age 47 (range 30-62) years].

A comparison of different two-dimensional approaches for the determination of the patellar tendon moment arm length.

The purpose of this study was to estimate and compare the moment arm length of the patellar tendon (d) during passive knee extension using three different reference landmarks; instant centre of rotation (ICR), tibiofemoral contact point (TFCP) and geometrical centre of the posterior femoral condyles (GCFC). Measurements were taken on the right leg on seven healthy males during passive knee rotation performed by the motor of a Cybex Norm isokinetic dynamometer. Moment arms lengths were obtained by analysing lateral X-ray images recorded using a GE FlexiView 8800 C-arm videofluoroscopy system.

WITHDRAWN: Interventions for treating calcaneal fractures.

Background: Fracture of the calcaneus (os calcis or heel bone) comprises one to two per cent of all fractures.

Objectives: To identify and evaluate randomised trials of treatments for calcaneal fractures.

Search Strategy: MEDLINE, EMBASE, CINAHL, the Cochrane Controlled Trials Register, and the Cochrane Musculoskeletal Injuries Group Trials Register were searched.

Achilles tendon ossification: pathology, imaging and aetiology.

Background: We report a patient with ossification of the Achilles tendon, presenting plain radiographs, ultrasound, power doppler, computed tomography and magnetic resonance findings. The majority of the tendon was ossified, and there was adjacent soft tissue oedema. The appearance of peritendinous oedema associated with ossification has not, to our knowledge, been reported in the literature, and could account for hindfoot pain in cases of tendon ossification.

Achilles tendon Doppler flow may be associated with mechanical loading among active athletes.

Background: Tendon Doppler flow may be associated with tendon pain in symptomatic patients, but the relationship between Doppler flow and pain among athletes who are still competing is unclear.

Hypothesis: Among active athletes, Doppler flow may partly reflect tendon adaptation to increased mechanical load and/or asymptomatic tendinopathy.

Study Design: Cross-sectional study; Level of evidence, 3.

The distribution of sexually-transmitted Human Papillomaviruses in HIV positive and negative patients in Zambia, Africa.

Background: Human Papillomaviruses (HPV) are double-stranded DNA viruses, considered to be the primary etiological agents in cervical intraepithelial neoplasias and cancers. Approximately 15-20 of the 40 mucosal HPVs confer a high-risk of progression of lesions to invasive cancer. In this study, we investigated the prevalence of sexually transmitted HPVs in Human Immunodeficiency Virus (HIV) positive and negative patients in Zambia, Africa.

In vivo changes in the human patellar tendon moment arm length with different modes and intensities of muscle contraction.

The purpose of this study was to examine the effect of different muscle contraction modes and intensities on patellar tendon moment arm length (d(PT)). Five men performed isokinetic concentric, eccentric and passive knee extensions at an angular velocity of 60 deg/s and six men performed gradually increasing to maximum effort isometric muscle contractions at 90( composite function) and 20( composite function) of knee flexion. During the tests, lateral X-ray fluoroscopy imaging was used to scan the knee joint.

Subcutaneous rupture of the Achilles tendon and ipsilateral fracture of the medial malleolus.

Background: Although ankle fractures and an Achilles tendon rupture are relatively frequent in isolation, their association in the same injury is uncommon.

Case Presentation: A 38 year old male tree surgeon fell six meters from a tree, sustaining a subcutaneous rupture of the Achilles tendon and an ipsilateral closed fracture of the medial malleolus. The injuries were diagnosed following clinical examination and imaging.
