AI Article Synopsis
- This study assessed the occurrence of greater trochanter pain syndrome (GTPS) in patients undergoing hip magnetic resonance arthrography (MRA) for suspected femoroacetabular impingement (FAI).
- It analyzed data from 189 patients, finding that 39.2% were diagnosed with GTPS, with a higher incidence in those with normal hip morphology compared to those with FAI.
- Results indicated that younger patients (under 40) with normal hip anatomy or pincer-type FAI had a greater likelihood of developing GTPS compared to older patients.
Article Abstract
Objectives: We evaluated the incidence of greater trochanter pain syndrome (GTPS) in patients who underwent magnetic resonance arthrography (MRA) of the hip for a suspected femoroacetabular impingement (FAI) syndrome.
Methods: Hip MRA performed at our institution (3/2012-1/2014) were reviewed. The absence/presence of FAI (cam, pincer, and mixed) was noted. GTPS diagnosis was based on gluteus medius/minimus tendinopathy/tears, trochanteric bursitis, fascia lata thickening, and trochanter bone oedema/erosion. Subgroup analysis for age (under/over 40 years) and FAI type (cam, pincer, and mixed) was also performed.
Results: N = 189 patients were included (n = 125 males; age 39 ± 12 years). FAI was diagnosed in n = 133 (70, 4%): cam type, n = 85 (63, 9%); pincer type, n = 22 (16, 6%); and mixed type, n = 26 (19, 5%). N = 72 patients (38.1%) had tendinopathy, n = 14 (7.4%) had trochanter erosion, n = 31 (16.4%) had bursitis, n = 4 had bone oedema (2.1%), and n = 3 (1.6%) had fascia lata thickening, resulting in GTPS diagnosis in n = 74 patients (39.2%). The association of normal hip morphology/GTPS was significantly higher (P = 0.023) than that of FAI/GTPS. Under 40 years, GTPS incidence was higher in patients with normal hip and pincer-type FAI (P = 0.028). Over 40 years, no difference between patients with/without FAI (P = 0.119) was seen.
Conclusions: GTPS was more frequently observed in patients with normal hip morphology than in patients with FAI, particularly in patients under 40.

Background: Premorbid sarcopenia, osteoporosis, and obesity are epiphenomena that affect survival and functional outcomes in patients with acute ischemic stroke. The effects of preexisting sarcopenia and/or osteopenia on long-term outcome after ischemic stroke were herein prospectively studied.
Methods: Dual-energy x-ray absorptiometry (DeXA), bio-impedance analysis (BIA) and muscle ultrasonography (US) data were prospectively collected within the first 72 hours in 297 consecutive acute ischemic stroke patients (45.
Do patients with minimally displaced distal radial fractures need a plaster cast?
Bone Joint J

Kolding Hospital, Kolding, Denmark.
Traditionally, patients with a fracture of the distal radius are treated in a cast if they do not require surgery. If the fracture requires manipulation, the cast is moulded to hold the reduction and maintain normal anatomical alignment during healing. However, is a cast necessary for patients whose fracture does not require manipulation? Removable splints are an alternative treatment option.

Betaine exhibits significant physiological functions in organisms and has positive impacts on obesity, alcohol-induced and metabolic-associated liver disease, diabetes, cardiovascular diseases, and certain cancers. However, the evidence from epidemiological studies is limited and inconsistent. This study aimed to investigate the association between dietary betaine intake and the incidence of overweight or obesity.

Background: As a non drug and non invasive therapy, both transcranial alternating current stimulation (tACS) and transcranial direct current stimulation (tDCS) may modulate cortical rhythms and serve as potentially effective approaches to cognitive decline in Alzheimer's disease (AD). However, studies using animal models of AD are quite limited.
Methods: This study investigates the aftereffects of tACS and tDCS on brain EEG activity and associated exploratory behavior in normal aged and APP/PS1 transgenic mice (15 months old).
Elevated neurofilament light chain associated with cobalt/chromium metal neurotoxicity in a patient with a failed hip implant.

Background: It is known that the heavy metals cobalt and chromium are associated with neurotoxicity. Chromium (Cr) and Cobalt (Co) are both components of metal-on-metal (MoM) implants which can be degraded/fragmented and released into the bloodstream. Neurofilament Light Chain (NfL) is a neuron-specific protein that increases in serum following axonal damage.
