INTRODUCTION: Segmental instability due to lumbar spondylolisthesis is a potential cause of chronic low back pain. Hypomobility of the spine results in compensatory segmental hypermobility of the segment above or below restricted segments. Therefore, the aim of the study is to determine the effects of mobilisation of the hypomobile upper thoracic spine along with conventional flexion exercises and stretching of short hip flexors on the degree of slippage and the functions of the persons with lumbar spondylolisthesis...

Although the anuran pelvis is thought to be adapted for jumping, the function of the iliosacral joint has seen little direct study. Previous work has contrasted the basal "lateral-bender" pelvis from the "rod-like" pelvis of crown taxa hypothesized to function as a sagittal hinge to align the trunk with take-off forces. We compared iliosacral movements and pelvic motor patterns during jumping in the two pelvic types. Pelvic muscle activity patterns, iliosacral anteroposterior (AP) movements and sagittal bending of the pelvis during the take-off and landing phases were quantified in lateral bender taxa Ascaphus (Leiopelmatidae) and Rhinella (Bufonidae) and the rod-like Lithobates (Ranidae)...

AIMS: We wished to quantify the extent of soft-tissue damage sustained during minimally invasive total hip arthroplasty through the direct anterior (DA) and direct superior (DS) approaches. MATERIALS AND METHODS: In eight cadavers, the DA approach was performed on one side, and the DS approach on the other, a single brand of uncemented hip prosthesis was implanted by two surgeons, considered expert in their surgical approaches. Subsequent reflection of the gluteus maximus allowed the extent of muscle and tendon damage to be measured and the percentage damage to each anatomical structure to be calculated...

AIM: Lately, the diagnostic value of magnetic resonance imaging, Lasègue sign and classic neurological signs have been considered not accurate enough to distinguish the radicular from non-radicular low back with leg pain (LBLP) and a calculation of the symptomatic side muscle volume has been indicated as a probable valuable marker. However, only the multifidus muscle volume has been calculated so far. The main objective of the study was to verify whether LBLP subjects presented symptomatic side pelvic muscle atrophy compared to healthy volunteers...

: The piriformis fossa is the ideal portal of entry for antegrade interlocking nailing. Localizing this portal can be difficult and its eccentricity leads to complications. This prospective comparative study was designed to compare an innovative way to obtain the ideal portal from inside the medullary canal in cases of plate failure and compare it to the classic antegrade portal. It included 41 cases (19 antegrade and 22 retrograde). The retrograde portal was significantly better in terms of entry time, radiation time, blood-loss, and wound length...

INTRODUCTION: The retromolar pad also called piriformis papilla is a mucosal elevation located in the retromolar area covering the retromolar triangle. After molar loss, the bony alveolar process and surrounding soft periodontal tissue remodel, mainly resorb and blend with retromolar pad. It is a key intraoral landmark in prosthodontics. AIM: The aim of this in-vitro study was to analyze the various anatomical shapes and sizes of retromolar pad in 150 completely edentulous patients between 55 to 70 years of age group...

A growing body of literature indicates that many synthetic pesticides have adverse effects on human, animal, and environmental health. As a result, plant-derived natural products are quickly gaining momentum as safer and less ecologically damaging alternatives due to their low toxicity, high biodegradability, and good specificity. Essential oils of Lavandula angustifolia, Lavandula x intermedia cv Grosso, and Lavandida x intermedia cv Provence as well as various mono- and sesquiterpene essential oil constituents were tested in order to assess their antifungal potential on three important agricultural pathogens: Botrytis cinerea, Mucor piriformis, and Penicillium expansum...

Lower limb joint loadings are increased during sloped walking compared to level walking and muscle forces are major contributors to lower limb joint forces. Therefore, the aim of this study was to analyze lower limb muscle forces during sloped walking at different inclinations. Eighteen healthy male participants (27.0±4.7y, 1.80±0.05m, 74.5±8.2kg) walked at a pre-set speed of 1.1m/s on a ramp at the inclinations of 0°, ±6°, ±12° and ±18°. Kinematic data were captured with a motion capture system and kinetic data were recorded with two force plates imbedded into the ramp...

Intramuscular injections are likely the most common cause of sciatic nerve injury in developing countries. Less common causes include piriformis syndrome, primary tumors of the sciatic nerve, metastatic tumors invading or compressing the nerve, endometriosis, vascular malformations, and prolonged immobilization or positioning. While the most reliable diagnostic and prognostic methods include nerve conduction studies and electromyography, magnetic resonance imaging has been suggested as an alternative method of determining type of lesion, establishing location, and investigating level of nerve involvement...

Polytomella is a genus of colorless green algae in the Reinhardtinia clade of the Chlamydomonadales, which has proven useful for a broad range of studies particularly those exploring the evolutionary loss of photosynthesis and mitochondrial genomics/biochemistry. Although 13 Polytomella strain accessions are currently available from public culture collections, the taxonomic status and redundancy of many of these strains is not clear because of possible mix-ups, deficient historical records, and incomplete molecular data...

Subject-specific musculoskeletal (MS) models of the lower extremity are essential for applications such as predicting the effects of orthopedic surgery. We performed an extensive sensitivity analysis to assess the effects of potential errors in Hill muscle-tendon (MT) model parameters for each of the 56 MT parts contained in a state-of-the-art MS model. We used two metrics, namely a Local Sensitivity Index (LSI) and an Overall Sensitivity Index (OSI), to distinguish the effect of the perturbation on the predicted force produced by the perturbed MT parts and by all the remaining MT parts, respectively, during a simulated gait cycle...

Avascular necrosis (AVN) of femoral head is a recognised complication of fracture dislocation of the hip joint but is not studied frequently in relation to acetabulum fractures. The aim was to establish the relationship between obturator externus and piriformis muscle morphology in acetabulum fractures and potenital development of AVN of the femoral head. Twenty-five fractures were included in this prospective study and were subjected to radiological assessment and computed tomography of the pelvis. Magnetic resonance imaging (MRI) of the hip was performed to assess the morphology of obturator externus and piriformis, and findings were compared intraoperatively (in 15 cases)...

Piriformis syndrome is an uncommon cause of buttock and leg pain. Some treatment options include the injection of piriformis muscle with local anesthetic and steroids. Various techniques for piriformis muscle injection have been described. Ultrasound allows direct visualization and real time injection of the piriformis muscle. We describe 5 consecutive patients, diagnosed of piriformis syndrome with no improvement after pharmacological treatment. Piriformis muscle injection with local anesthetics and steroids was performed using an ultrasound technique based on a standard technique...
