The distribution of cartilage thickness in the knee-joints of old-aged individuals -- measurement by A-mode ultrasound.
1997
Abstract Objective. To provide data on the normal distribution of cartilage thickness in the knee joints of old-aged individuals. Design. The accuracy and reproducibility of cartilage thickness measurements were evaluated with A-mode ultrasound, and the cartilage thickness distribution was examined throughout both knee joints of nine individuals aged between 62 and 94 yr. Background. Data on the variation of cartilage thickness in the joint surfaces are relevant for the design of computer models of diathrodial joints and for surgical and arthroscopic procedures, particularly the calculation of cartilage material properties from indentation tests. Methods. A 12.5 MHz A-mode ultrasound transd…
Ultrastructure of Dural Lesions Produced in Lumbar Punctures
2014
During lumbar puncture, the insertion of a single-use, short-beveled spinal needle produces a “tent-like” effect. The dura-arachnoid lesions produced by this Quincke type of needles show a “crescent moon” shape resembling the letter “U” or “V” (similar to the lid of a can), with clean-cut edges. As the needle tip advances, the cut fragment is folded inwards, while all dural and arachnoid layers are entirely severed and the edges of the lesion are displaced inwardly. As soon as the spinal needle is withdrawn, the edges of the lesion tend to retract, owing to the viscoelastic properties of the affected dura mater.
A new tool to improve pedicle screw placement accuracy in navigated spine surgery: A monocentric study
2021
Objective Navigated instrumented spine surgery is burden by a low but significant screw mispositioning risks, respectively, for the 2D imaging system from 15 to 40% and, for the 3D imaging system, ranging from 4.1 to 11.5%. The primary objective of this study was to demonstrate the efficacy of a new "screw-like" tool in order to further decrease pedicle screws mispositioning rate during vertebral navigated spine surgery. Materials and methods Between January and June 2019 an initial case series of 18 patients were enrolled. All patients underwent a pedicle screw fixation, both in thoracic (Th10-Th12) and lumbosacral (L1-S1) spine, using O-arm (Medtronic Navigation, Louisville, Colorado) and…
The impact of multilevel surgery on functional abilities and participation in adolescents with cerebral palsy (CP)
2013
but not significant decrease in RT group. Timing of pKFSw, range of knee flexion and knee flexion velocity improved after surgery but tended to deteriorate over the years in either group. Discussionandconclusions:The results of thepresent study for the first time suggest that the influences of proximal RF release on DRFT effects on the knee joint are negligible. Two possible explanations shouldbe considered. First, thefindingsmaybe explainedby a permanent eliminationofRF functionon thekneeafterDRFT,which would be unaffected by proximal release and would underline the efficiency of DRFT. Secondly, surgery in the proximal part does not influence the distal part. This would represent a new imp…
Acupuncture in the treatment of temporomandibular disorders, facial pain, and postural neuromuscular disorders. Presentation of a clinical case
2021
Abstract Background and objectives Temporomandibular disorders have a multifactorial etiology and involve the masticatory muscles, temporomandibular joint and associated structures. Therefore, different treatments are proposed and used. The aim of this paper is the use of acupuncture to treat temporomandibular disorders and associated symptoms. This article presents a clinical case study of a 39-year-old patient who presented temporomandibular disorders and headache of muscular origin. Results After 10 acupuncture sessions, the results were highly satisfactory, with complete relief of headache pain and absence of joint disorders. These results suggest the efficacy of acupuncture in the symp…
Impaired geometric properties of tibia in older women with hip fracture history.
2007
This study evaluated side-to-side differences in tibial mineral mass and geometry in women with previous hip fracture sustained on average 3.5 years earlier. Both tibial mineral mass and geometry were found to be reduced in the fractured leg. INTRODUCTION: The purpose of this study was to evaluate side-to-side differences in tibial mineral mass and geometry after hip fracture and to assess the determinants of such differences. METHODS: Thirty-eight 60- to 85-year-old women with a previous hip fracture and 22 same-aged control women without fractures participated in the study. Bone characteristics of the distal tibia and tibial shaft of both legs were assessed using pQCT in order to compare …
Training-induced increase in Achilles tendon stiffness affects tendon strain pattern during running
2019
Background During the stance phase of running, the elasticity of the Achilles tendon enables the utilisation of elastic energy and allows beneficial contractile conditions for the triceps surae muscles. However, the effect of changes in tendon mechanical properties induced by chronic loading is still poorly understood. We tested the hypothesis that a training-induced increase in Achilles tendon stiffness would result in reduced tendon strain during the stance phase of running, which would reduce fascicle strains in the triceps surae muscles, particularly in the mono-articular soleus. Methods Eleven subjects were assigned to a training group performing isometric single-leg plantarflexion co…
Patología articular en la enfermedad inflamatoria intestinal
2005
The joint disorders taxonomically included in the group of seronegative spondyloarthropathies under the generic name of enteropathic arthropathy represent the most frequent extra-intestinal manifestation of inflammatory bowel disease (IBD), affecting 33% of patients. Their frequency is similar to that of ulcerative colitis and Crohn's disease. Enteropathic arthropathy consists of two main joint alterations, peripheral and axial arthritis, as well as a variable group of other peri-articular disorders. Type 1, or pauciarticular, peripheral arthritis generally coincides with IBD exacerbations, while type 2, or polyarticular, peripheral arthritis follows an independent course from IBD. Axial in…
A10.8 Evaluation of Disease Activity in Adult Patients with Juvenile Idiopathic Arthritis
2013
Background Juvenile idiopathic arthritis (JIA) is a disease which maintains specific childish rheumatological features during whole life. There is still an open discussion which criteria of the disease activity should be used for the management of adult patients with JIA. Objectives To analyse the usefulness of known disease activity and functional indices used in adult rheumatological practise for the assessment of rheumatoid arthritis (RA) and spondyloarthritidies (SpA): disease acitivity score (DAS), disease acitivity score 28 (DAS28), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Spondylitis Functional Index (BASFI), Health Assessment Questionnaire – disability index…

2014
5 Office-based Professional Association Gynecologic Oncologists e.V. in Germany (BNGO e.V.), Berlin; 6 Background: This prospective study evaluated the relationship between arthralgia and compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. Patients and methods: COMPliance and Arthralgia in Clinical Therapy (COMPACT) was an open-label, multicenter, noninterventional study conducted in Germany. Patients had started adjuvant anastrozole 3-6 months before the study start. The primary end points were arthralgia, compliance, and the relationship between compliance and arthralgia, assessed at specific time poi…
