BACKGROUND: Bone loss in patients undergoing revision THA poses a considerable challenge for orthopaedic surgeons. Often, to achieve better fixation in remaining bone, larger diameter acetabular components and reaming superiorly may be necessary. However, this is likely to raise the hip center of rotation, which may lead to altered biomechanics, specifically, insufficiency of the abductor muscles, altered gait, and increased risk of dislocation from impingement. More recently, a newer acetabular shell has been designed to more closely replicate the native hip center of rotation in these circumstances while maintaining adequate fixation...

Study Design Controlled laboratory study, case-control design. Background Despite recognition that femoroacetabular impingement syndrome (FAIS) is a movement-related disorder, few studies have examined dynamic unilateral tasks in individuals with FAIS. Objectives 1) Determine if individuals with FAIS have different pelvis and lower extremity movements than individuals without hip pain during a single leg stepdown. 2) Analyze kinematic differences between males and females within groups. Methods Individuals with FAIS and individuals without hip pain performed a single leg stepdown while kinematic data were collected...

Background: Impaired patient-reported shoulder function and pain, external-rotation strength, abduction strength, and abduction range-of-motion (ROM) is reported in patients with subacromial impingement (SIS). However, it is unknown how much strength and ROM improves in real-life practice settings with current care. Furthermore, outcomes of treatment might depend on specific rehabilitation parameters, such as the time spent on exercises (exercise-time), number of physiotherapy sessions (physio-sessions) and number of corticosteroid injections, respectively...

Many patients are afflicted with painful conditions affecting both hips, most commonly femoroacetabular impingement. Some patients prefer the advantage of undergoing a single surgical procedure and anesthetic followed by a single postoperative rehabilitation program. We present a Technical Note on single-stage bilateral hip arthroscopy. This Technical Note reports on key steps enabling safe and efficient performance of bilateral arthroscopic acetabuloplasty, labral refixation, femoroplasty, and dynamic testing while limiting traction times and facilitating rapid transition to the second hip arthroscopic surgery...

Background and Purpose: Secondary impingement syndrome (SIS) is a common complaint in the sporting population particularly among athletes engaging in overhead activities. While symptoms may be present at the shoulder with patients complaining of SIS, spinal alignment or dysfunction can influence scapular positioning and overall shoulder girdle function. As an adjunct therapy to traditional interventions for SIS, thoracic high-velocity low-amplitude (HVLA) thrusts have been utilized and correlated with patient reported decreases in pain...

BACKGROUND: Hip osteoarthritis has been reported in the contralateral hip in patients who had been treated for unilateral slipped capital femoral epiphysis (SCFE) during adolescence. Although this might be related to the presence of a mild deformity, the morphologic features of the contralateral hip in unilateral SCFE remains poorly characterized. QUESTIONS/PURPOSES: Do measurements of (1) femoral head-neck concavity (α angle and femoral head-neck offset), (2) epiphyseal extension into the metaphysis (epiphyseal extension ratio and epiphyseal angle), and (3) posterior tilt of the epiphysis (epiphyseal tilt angle) differ between the contralateral asymptomatic hips of patients treated for unilateral SCFE and hips of an age- and sex-matched control population without a history of hip disease? METHODS: From January 2005 to May 2015, 442 patients underwent surgical treatment for SCFE at our institution...

The frontotempotal-orbitozygomatic craniotomy (FTOZ) is a standard approach for large sphenoid wing meningiomas (SWMs). Nevertheless, resection of these tumors is not without ophthalmologic risks. This series presents two patients with acute postoperative restrictive strabismus following tumor resection and orbital wall reconstruction. Forced duction testing and postoperative imaging revealed impingement of the lateral rectus muscle caused by an alloplastic implant and/or residual bone, prompting immediate orbitotomy and restoration of normal extraocular muscle function...

Amorphous powders are thermodynamically unstable, significantly impacting the processing, storage and performance of a product. Therefore, stabilization of the amorphous contents is in demand. In this study, disodium cromoglycate (DSCG) powder was chosen as a model drug because it is amorphous and highly hygroscopic after spray drying. Sodium stearate (NaSt) was co-spray dried with DSCG at various concentrations (10, 50 and 90% w/w) to investigate its effect against moisture-induced deterioration on the in vitro aerosolization performance of DSCG...

BACKGROUND: The Neer, Hawkins, and Yocum clinical tests detect sub-acromial impingement as a pathogenic process of degenerative rotator cuff disease. Their reproducibility has been little investigated. OBJECTIVES: We tested the reproducibility of the Neer, Hawkins, and Yocum clinical tests for detecting this sub-acromial impingement and also an original clinical manoeuver, the countertest with elevation with lateral rotation (CELR), which is a test of sub-acromial impingement...

This work investigates emissions sampling methods employed for qualitative identification of compounds in e-liquids and their resultant aerosols to assess what capture methods may be sufficient to identify harmful and potentially harmful constituents present. Three popular e-liquid flavors (cinnamon, mango, vanilla) were analyzed using qualitative gas chromatography-mass spectrometry (GC-MS) in the un-puffed state. Each liquid was also machine-puffed under realistic-use flow rate conditions and emissions were captured using two techniques: filter pads and methanol impingers...

Occupational exposure to swine has been associated with increased Staphylococcus aureus carriage, including antimicrobial-resistant strains, and increased risk of infections. To characterize animal and environmental routes of worker exposure, we optimized methods to identify S. aureus on operations that raise swine in confinement with antibiotics (industrial hog operation: IHO) versus on pasture without antibiotics (antibiotic-free hog operation: AFHO). We associated findings from tested swine and environmental samples with those from personal inhalable air samplers on worker surrogates at one IHO and three AFHOs in North Carolina using a new One Health approach...

This study is aimed at developing a novel analytical method to identify optimal inhalation flow patterns for commercial dry powder inhalers (DPIs) and pressurized metered dose inhalers (pMDIs). As typical commercial DPI and pMDI, Pulmicort® Turbuhaler® and Sultanol® Inhaler were evaluated by an in-vitro inhalation performance testing system with a flow pattern simulator. An 8-stage Andersen cascade impactor (ACI) or twin stage liquid impinger (TSLI) was applied to determine the inhalation performance. The peak flow rate (PFR) of the inhalation flow pattern was set from 15 to 80 L/min in reference to our previous study...

BACKGROUND: In symptomatic tendinosis, a corticosteroid injection into the subacromial space is a palliative treatment option. This study compares high volumes (10 cc) of local anesthetic (LA) combined with triamcinolone acetate (TA) with low volumes (4 cc) of LA combined with TA to see whether the latter would provide similar pain, function and complication outcomes for subacromial injections in patients with impingement syndrome. MATERIALS AND METHODS: This single-center, randomized, single-blind, non-inferiority trial included patients with shoulder pain and positive multiple clinical tests supporting the diagnosis of impingement syndrome...

BACKGROUND: Cervical foraminal impingement has been described as a source of radicular pain. Clinical tests and head motions have been reported for affecting the intervertebral foramen (IVF) dimensions. Although manual approaches are proposed in the management of cervical radiculopathy, their influence on the foraminal dimensions remains unclear. OBJECTIVES: To investigate the influence of pre-manipulative positioning versus cervical axial rotation on the foraminal dimensions of the lower cervical spine...

BACKGROUND: Lateral ankle ligament injury is among the most common orthopedic injuries. The objective of this study is to present the preliminary prospective results of treatment using the "Inside-Out" variant of the fully arthroscopic Broström-Gould technique. METHODS: Twenty six patients were included: 20 male and 6 female, aged 19-60 years, mean 41 years. All patients had positive "anterior drawer" and "talar tilt" tests. When necessary, cartilage injuries were treated with microfracture and arthroscopic resection for anterior impingement; three patients had hindfoot varus, on whom Dwyer osteotomy was performed; one patient had peroneal tendinopathy and was treated with tendoscopic debridement and another one had partial injury of the deltoid ligament, which was treated by direct repair...
