Large, engaging Hill-Sachs lesions can cause recurrent glenohumeral instability following Bankart repair of torn anterior capsulolabral structures. We offer a novel technique for correcting the posterolateral humeral head defect without significantly altering normal anatomic structures. The glenohumeral joint is exposed via a deltopectoral approach. After the defect geometry is appreciated by d...

Background: Autogenous osteochondral grafting of articular defect in weight-bearing surface of large joints has proven to be a proper biomechanical and physiological solution for localized full-thickness defects.Objective: To study the gross and histopathological results of mosaicplasty in an animal model (sheep’s medial femoral condyle), evaluating the factors of defect and graft size, assessi...

The synthetic material Nanobone(®) (hydroxyapatite nanocrystallines embedded in a porous silica gel matrix) was examined in vivo using a standardized bone defect model in the ovine tibial metaphysis. A standardized 6 × 12 × 24-mm bone defect was created below the articular surface of the medial tibia condyles on both hind legs of 18 adult sheep. The defect on the right side was filled with Nano...

We have examined the relationship between insulin-induced receptor downregulation and the induction of a postreceptor defect in the insulin-stimulated glucose transport system in rat adipocytes, and found that downregulation was linked to the expression of the postreceptor defect. When recycling of insulin receptors was inhibited by 20 mM Tris, insulin pretreatment (100 ng/ml) for 4 h at 370C i...

BACKGROUND The current study describes several surgical techniques for the treatment of the reverse Hill - Sachs lesion after posterior shoulder dislocation; we also aimed to present long term results followed for a minimum of five years. METHODS This study is a prospective case series of 17 patients who were treated in our clinic between 2008 and 2011. Patients with a defect size smaller tha...

Pulsed Phase Thermography (PPT) has been successfully applied for defect detection purposes on a variety of materials. A great deal of work has been done to evaluate the potential of PPT for quantitative applications, using for instance statistical methods, Neural Networks or wavelets (Ibarra-Castanedo et al., 2004). However, calibration requirements and lengthy computation subroutines, preclud...

Subcutaneous stitches are placed in an effort to close dead space and aid in tissue edge approximation when repairing a surgical defect, but overcoming tension to approximate wound edges in surgical defects may be particularly difficult to accomplish in situations such as extreme defect width, location of the defect over a convex surface, inelasticity or rigidity of tissue, and excessive recoil...

Posterior lenticonus is a congenital defect of the posterior lenticular surface. The posterior cortical and capsular regions of the lens have a circumscribed conelike or globular protrusion of variable size. Opacities may be present in the region of the conus. The defect has been reported in man, rabbits, calves and mice. This report documents 2 cases in unrelated dogs. The possible mechanism f...
