The standing knee lift test is not a useful screening tool for time loss from low back pain in youth basketball and floorball players
2021
Abstract Objectives The aim of this study was to investigate the association between pelvic kinematics during the standing knee lift (SKL) test and low back pain (LBP) in youth floorball and basketball players. Design A prospective cohort study. Setting Finnish elite youth floorball and basketball players. Participants Finnish elite youth female and male floorball and basketball players (n = 258, mean age 15.7 ± 1.8). Main outcome measures LBP resulting in time loss from practice and games was recorded over a 12-month period and verified by a study physician. Associations between LBP and sagittal plane pelvic tilt and frontal plane pelvic obliquity during the SKL test as measured at baselin…
Correlation between chronic prostatitis syndrome and pelvic venous disease: a survey of 2,554 urologic outpatients.
2000
Objectives: In this study we evaluated the association between chronic prostatitis syndrome (CPS), varicocele and hemorrhoids as manifestations of a pelvic venous disease. Methods: Our retrospective study was based upon 2554 patients treated in two general urology clinics over the past 10 years. We have assessed the incidence of CPS among urological patients. Results: We found 483 patients with CPS, representing 18.9% of the total number of visits at the outpatient clinic. In this group the percentage of varicocele and hemorrhoids was 14.69 and 8.48%, whereas in a control group these figures were 5.02 and 5.84%, respectively (p < 0.001 and 0.1054). Such a difference is statistically sign…
Which functional tasks present the largest deficits for patients with total hip arthroplasty before and six months after surgery? A study of the time…
2021
Six to eight months after total hip arthroplasty, patients only attain 80% of the functional level of control groups. Understanding which functional tasks are most affected could help reduce this deficit by guiding rehabilitation towards them. The timed up-and-go test bundles multiple tasks together in one test and is a good indicator of a patient’s overall level of function. Previously, biomechanical analysis of its phases was used to identify specific functional deficits in pathological populations. To the best of our knowledge, this analysis has never been performed in patients who have undergone total hip arthroplasty. Seventy-one total hip arthroplasty patients performed an instrumente…
Do We Need a Separate Classification for Fragility Fractures of the Pelvis?
2019
Fragility fractures of the pelvis are occurring with increasing frequency. These fractures, occurring in the geriatric patient population, are low-energy injuries and are dissimilar in many ways from those caused by high-energy trauma. For example, the mechanism of injury is different and emergency treatment is usually not necessary. Having diminished bone strength, fragility fracture lines follow areas of low bone mineral density and loss of pelvic stability may increase over time. Based on our clinical experience, we propose a comprehensive classification of pelvic fragility fractures separate from the existing pelvic ring injury classification to provide a framework for distinguishing th…
Automatic classification of tissues on pelvic MRI based on relaxation times and support vector machine
2019
International audience; Tissue segmentation and classification in MRI is a challenging task due to a lack of signal intensity standardization. MRI signal is dependent on the acquisition protocol, the coil profile, the scanner type, etc. While we can compute quantitative physical tissue properties independent of the hardware and the sequence parameters, it is still difficult to leverage these physical properties to segment and classify pelvic tissues. The proposed method integrates quantitative MRI values (T1 and T2 relaxation times and pure synthetic weighted images) and machine learning (Support Vector Machine (SVM)) to segment and classify tissues in the pelvic region, i.e.: fat, muscle, …
A multicenter 12-month experience with a new iliac side-branched device for revascularization of hypogastric arteries.
2016
Abstract Objective The aim of this study was to investigate the 1-year safety and efficacy of a new iliac side-branched device (IBD) for revascularization of the hypogastric arteries. Methods Patients receiving the E-liac (Jotec GmbH, Hechingen, Germany) side-branched device at six German vascular centers either as a stand-alone procedure or in combination with abdominal aortic aneurysm exclusion were included in a prospectively created data bank. Collected data were analyzed for baseline characteristics, procedural events, and clinical follow-up; variables included endoleaks, reinterventions, and internal iliac artery (IIA) patency. Results Between January 2012 and January 2015, a total of…
Mandibular-pelvic-patellar syndrome (mpp) is a novel pitx1-related disorder due to alteration of pitx1 transactivation ability
2020
International audience; PITX1 is a homeobox transcription factor essential for hindlimb morphogenesis. Two PITX1-related human disorders have been reported to date: PITX1 ectopic expression causes Liebenberg syndrome, characterized by malformation of upper limbs showing a "lower limb" appearance; PITX1 deletions or missense variation cause a syndromic picture including clubfoot, tibial hemimelia, and preaxial polydactyly. We report two novel PITX1 missense variants, altering PITX1 transactivation ability, in three individuals from two unrelated families showing a distinct recognizable autosomal dominant syndrome, including first branchial arch, pelvic, patellar, and male genital abnormaliti…
Performance in dynamic movement tasks and occurrence of low back pain in youth floorball and basketball players
2020
Abstract Background Prospective studies investigating risk factors for low back pain (LBP) in youth athletes are limited. The aim of this prospective study was to investigate the association between hip-pelvic kinematics and vertical ground reaction force (vGRF) during landing tasks and LBP in youth floorball and basketball players. Methods Three-hundred-and-eighty-three Finnish youth female and male floorball and basketball players (mean age 15.7 ± 1.8) participated and were followed up on for 3 years. At the beginning of every study year the players were tested with a single-leg vertical drop jump (SLVDJ) and a vertical drop jump (VDJ). Hip-pelvic kinematics, measured as femur-pelvic angl…
A successful backward step correlates with hip flexion moment of supporting limb in elderly people.
2018
Purpose The objective of this study was to determine the positional relationship between the center of mass (COM) and the center of pressure (COP) at the time of step landing, and to examine their relationship with the joint moments exerted by the supporting limb, with regard to factors of the successful backward step response. Methods The study population comprised 8 community-dwelling elderly people that were observed to take successive multi steps after the landing of a backward stepping. Using a motion capture system and force plate, we measured the COM, COP and COM-COP deviation distance on landing during backward stepping. In addition, we measured the moment of the supporting limb joi…
Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.
1985
Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 mon…
