Diaphragm reconstruction with autologous fascia lata: Report of a case

When the diaphragm is excised so wiely that the defect cannot be closed directly during an operation on either thoracic or epigastric tumors, a reconstruction of the defect is necessary. We used harvested autologous fascia lata to reconstruct the diaphragm in a patient undergoing a pleuropneumonectomy with a partial diaphragmatic resection for malignant mesothelioma.

狗硬脑膜与阔筋膜承受拉力比较

目的比较狗阔筋膜和硬脑膜所能承受拉力的差异.方法使用XL-250A型拉力实验机分别测定同期、相同条件下取得的狗阔筋膜和硬脑膜所能承受的最大拉力.结果两种不同方向的阔筋膜的拉力强度无显著差别,阔筋膜与硬脑膜二者之间的拉力强度差别不显著,然而,二者之间每毫米所承受的拉力差别显著.结论用阔筋膜修复硬脑膜缺损足以支持脑组织.     

Postoperative Changes In The Tensor Fascia Lata Muscle After Using The Modified Anterolateral Approach For Total Hip Arthroplasty

The modified Watson-Jones approach to the hip has been described as a minimally invasive approach with the potential for fewer postoperative complications than the traditional approach. Because the approach relies on an intermuscular rather than an internervous plane, there is potential for injury to the superior gluteal nerve. The aim of this study was to evaluate incidence of tensor fascia lata (TFL) denervation in patients undergoing this approach. Twenty-six patients underwent total hip arthroplasty (THA) using a modified anterolateral approach. Postoperative MRIs were analyzed for signs of muscle denervation including atrophy, hypertrophy and fat replacement. At a median follow-up of 9.3 months, 74% of patients exhibited either atrophy or hypertrophy of the TFL and 42% exhibited fat replacement on MRI.     

Subcutaneous Tissue Mechanical Behavior is Linear and Viscoelastic Under Uniaxial Tension

Subcutaneous tissue is part of a bodywide network of “loose” connective tissue including interstitial connective tissues separating muscles and surrounding all nerves and blood vessels. Despite its ubiquitous presence in the body and its potential importance in a variety of therapies utilizing mechanical stretch, as well as normal movement and exercise, very little is known about loose connective tissue's biomechanical behavior. This study aimed to determine elastic and viscoelastic mechanical properties of ex-vivo rat subcutaneous tissue in uniaxial tension with incremental stress relaxation experiments. The elastic response of the tissue was linear, with instantaneous and equilibrium tensile moduli of 4.77 kPa and 2.75 kPa, respectively. Using a 5 parameter Maxwell solid model, material parameters μ₁ = 0.95 ± 0.24 Ns/m and μ₂ = 8.49 ± 2.42 Ns/m defined coefficients of viscosity related to time constants τ_1M = 3.83 ± 0.15 sec and τ_2M = 30.15 ± 3.16 sec, respectively. Using a continuous relaxation function, parameters C = 0.25 ± 0.12, τ_1C = 1.86 ± 0.34 sec, and τ_2C = 110.40 ± 25.59 sec defined the magnitude and frequency limits of the relaxation spectrum. This study provides baseline information for the stress-strain behaviors of subcutaneous connective tissue. Our results underscore the differences in mechanical behaviors between loose and high-load bearing connective tissues and suggest that loose connective tissues may function to transmit mechanical signals to and from the abundant fibroblasts, immune, vascular, and neural cells present within these tissues.
