Osteoprotegerin: a new biomarker for impaired bone metabolism in complex regional pain syndrome?
2014
Abstract Osteoprotegerin (OPG) is important for bone remodeling and may contribute to complex regional pain syndrome (CRPS) pathophysiology. We aimed to assess the value of OPG as a biomarker for CRPS and a possible correlation with radiotracer uptake in 3-phase bone scintigraphy (TPBS). OPG levels were analyzed in 23 CRPS patients (17 women; mean age 50 ± 9.0 years; disease duration: 12 weeks [IQR 8–24]), 10 controls (6 women; mean age 58 ± 9.6 years) and 21 patients after uncomplicated fractures (12 women; mean age: 43 ± 15 years; time after fracture: 15 weeks [IQR: 6–22]). The CRPS and control patients also underwent TPBS. OPG in CRPS patients was significantly increased by comparison wi…
Pain and clinical findings in the low back: a study of industrial employees with 5-, 10-, and 28-year follow-ups.
2009
Little is known about the relationships of clinical findings in the low back with low back pain (LBP) in the normal working population. We studied whether physiotherapist's findings in the low back were associated with local and radiating LBP among a cohort (n=902) of employees in the engineering industry. A systematic non-proportional sample was drawn in strata by age, gender, and occupational class. The non-proportionality aimed at increasing sample size in smaller strata. Physiotherapists performed the straight-leg raising test (SRL), and made assessments of the fingertip-to-floor distance and pain in palpation of the lumbar interspinous spaces. The variables on pain at the interspinous …
A comparison of lumbopelvic motion patterns and erector spinae behavior between asymptomatic subjects and patients with recurrent low back pain durin…
2015
Objectives: The purpose of this study was to determine the patterns of lumbopelvic motion and erector spinae (ES) activity during trunk flexion-extension movements and to compare these patterns between patients with recurrent low back pain (LBP) in their pain-free periods and matched asymptomatic subjects. Methods: Thirty subjects participated (15 patients with disc herniation and recurrent LBP in their pain-free periods and 15 asymptomatic control subjects). A 3-dimensional videophotogrammetric system and surface electromyography (EMG) were used to record the angular displacements of the lumbar spine and hip in the sagittal plane and the EMG activity of the ES during standardized trunk fle…
Urethral Reconstruction in Anterolateral Thigh Flap Phalloplasty: A 93-Case Experience
2019
BACKGROUND: Urethral reconstruction in anterolateral thigh flap phalloplasty cannot always be accomplished with one flap, and the ideal technique has not been established yet. In this article, the authors' experience with urethral reconstruction in 93 anterolateral thigh flap phalloplasties is reported. METHODS: Ninety-three anterolateral thigh phalloplasties performed over 13 years at a single center were retrospectively reviewed to evaluate outcomes of the different urethral reconstruction techniques used: anterolateral thigh alone without urethral reconstruction (n = 7), tube-in-tube anterolateral thigh flap (n = 5), prelaminated anterolateral thigh flap with a skin graft (n = 8), antero…
Effects of pregnancy on lumbar motion patterns and muscle responses.
2018
The kinematics of the lumbar region and the activation patterns of the erector spinae muscle have been associated with the genesis of low back pain, which is one of the most common complications associated with pregnancy. Despite the high prevalence of pregnancy-related low back pain, the biomechanical adaptations of the lumbar region during pregnancy remain unknown.This study analyzes lumbar spine motion and the activation pattern of the lumbar erector spinae muscle in healthy pregnant women.A case-control study.The study involved 34 nulliparous women (control group) and 34 pregnant women in the third trimester (week 36 ± 1).We recorded the parameters of angular displacement of the lumbar …
Chemical heterogeneity of amyloid in the carpal tunnel syndrome
1987
140 biopsies from 108 patients afflicted with the carpal tunnel syndrome were studied, 27 of whom showed deposition of amyloid, in 6 of them to such an extent that the amyloid was considered significant in the pathogenesis of the carpal tunnel syndrome. Morphologically, vessels and ligaments were affected and especially the peritendinous structures. As it was always part of generalized amyloidosis, the amyloid in the carpal tunnel consisted immunohistologically of amyloid A in three cases (including one case with simultaneous amyloid deposition of the AA- and the AB-type), of amyloid A kappa in one case, of amyloid of prealbumin origin in seventeen cases and of AB-amyloid in eight cases. We…
Bone Mass Distribution in the Sacrum
2017
The trabecular architecture and bone mass distribution of each bone follows biomechanical principles and is an adaption to the stress exhibited during lifetime. In patients with osteoporosis, the bone mass decreases and the bone microarchitecture changes. A distinct bone mass distribution in non-osteoporotic and osteoporotic individuals is demonstrated using statistical modelling in the sacrum. The authors studied the sacral bone mass distribution using a 3D statistical model based on clinical CT scans of 92 Europeans. In the group with worse general bone mass (less than 100 Houndsfeld Units (HU) measured in the body of L5), there were large areas of negative HU in the sacral alae. These “a…
Compliance and arthralgias in clinical therapy (COMPACT): Assessment of the incidence of arthralgia, therapy costs, and compliance in the first year …
2012
e11040^ Background: Aromatase Inhibitors (AI) are well established as adjuvant endocrine treatment for postmenopausal women with HR+ early breast cancer (EBC). However, clinical trial data show higher frequently of arthralgia with AI than tamoxifen. As arthralgia may be greatly influencing compliance to adjuvant therapy, we designed a prospective trial to collect real world data on the effects of AI-associated arthralgia on patient compliance, patient outcomes and treatment costs of arthralgia. Methods: COMPACT is an open, prospective non-interventional study (NCT00857012) assessing the incidence of arthralgia, therapy costs, and compliance within the first year of adjuvant anastrozole (AN…
Posterior perilunate carpal dislocation associated with a multifragmentary distal radius fracture.
2009
Summary Dorsal perilunate wrist dislocations are rare. Associated carpal bones or radial styloid process fractures can occur and be included in the current classifications. The authors report an unusual association of dorsal perilunate wrist dislocation with a multifragmentary distal radius fracture. Such traumatic entity has never been previously described. Poor functional outcome may justify the inclusion of associated complex forearm bone fractures in wrist dislocation classifications.
Biomechanical testing of different posterior fusion devices on lumbar spinal range of motion.
2019
Abstract Background Recent minimal-invasive posterior fusion devices are supposed to provide stability and obtain fusion in combination with interbody cages in the instrumented segment. The aim of the present study is to evaluate the primary stability of two minimal-invasive posterior prototypes compared to an established spinous process plate and standard pedicle screw instrumentation. Methods Seven fresh frozen human cadaver lumbar spines (L2–L5) were tested in a spinal testing device with a moment of 7.5 Nm. Spinal stability was determined as mean range of motion (RoM) in the segment L3/L4 during extension-flexion, lateral bending and axial rotation. The RoM was measured during five cond…
