Moreover, the study investigated correlation between BIA-based ASMM DXA-based bone mineral density (BMD). Overview Literature If reliable, BIA may be a useful alternative to DXA as screening tool for sarcopenia...
Abstract Fresh platelet-rich plasma (PRP) accelerates bone union in rat model. However, fresh PRP has a short half-life. We suggested freeze-dried (FD-PRP) prepared advance and investigated its efficacy vivo . Spinal posterolateral fusion was performed on 8-week-old male Sprague-Dawley rats divided into six groups based the graft materials (n = 10 per group): sham control, artificial (A hydroxyapatite–collagen composite) –alone, autologous bone, + fresh-PRP, FD-PRP preserved 8 weeks, human...
Introduction: Oblique lateral interbody fusion (OLIF) can achieve recovery of lumbar lordosis (LL) in minimally invasive manner. The current study aimed to evaluate the location intervertebral cages during OLIF terms LL correction.
Abstract Background Lumbar spinal disease causes disabilities in performing daily activities. Operative treatments are aimed at pain relief and rapid return to routine activity. Patient-based outcome measures used evaluate pathologies therapeutic effects associated with lumbar disease. Nevertheless, it remains unknown as how much such treatment improves activity levels. The purpose of the current study was measure changes levels before after surgery using a wearable tracker analyze...
Retrospective observational study.We considered the relationship between spinal alignment and skeletal muscle mass on clinical outcomes following a surgery for lumbar stenosis (LSS).There are no reports of preoperative factors predicting residual low back pain LSS.Our target population included 34 women (mean age, 74.4 years) who underwent LSS. Prior to 6 months after surgery, systemic bone mineral density lean soft tissue were measured using dual-energy X-ray absorptiometry. Skeletal index...
Age-related sarcopenia may cause physical dysfunction. We investigated the involvement of in dropped head syndrome (DHS). Our study subjects were ten elderly women with idiopathic DHS (mean age 75.1 years, range 55–89). Twenty age- and sex-matched volunteers 73.0, 58–83) served as controls. used a bioelectrical impedance analyzer (BIA) to analyze body composition, including appendicular skeletal muscle mass index (SMI; lean (kg)/(height (m))2). SMI <5.75 was considered diagnostic for...
Retrospective observational study.To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) foraminal (FS) using tensor imaging (DTI).It is important in the selection surgical procedure IS FS, but such discrimination difficult.There were 9 cases IS, 7 5 healthy controls. The regions interest established zone (Iz), nerve root (N), extraforaminal (Ez). FA ADC measured on affected unaffected...
Limb muscle mass measurement using dual-energy X-ray absorptiometry (DXA) is considered the gold standard for diagnosis of sarcopenia. Moreover, bioelectrical impedance analysis (BIA) also recognized as a beneficial tool considering its high correlation with DXA. However, it remains to be elucidated whether DXA and BIA can accurately measure trunk lean mass. The aim this study was investigate between measurements cross-sectional area (CSA) muscles measured magnetic resonance imaging (MRI)...
Introduction: Failed spinal fusion surgery sometimes requires salvage when symptomatic, especially with postsurgical decrease in intervertebral disc height followed by foraminal stenosis. For such cases, an anterior approach to lumbar lateral interbody (LLIF) provides safe, direct access the pathological space and a potential improvement rate. One LLIF approach, oblique (OLIF), targets window of discs achieve successful fusion. The current technical note describes revision using OLIF procedure.
