us tear and menisectomy. The results of finite element analysis can explain partially biomechanical mechanisms of meniscus which can provide theoretical guidance for clinical treatment of meniscus injury.
The established finite element model of knee joint are proved to be have validity, and is a useful model for finite element analysis of meniscus tear and menisectomy. The results of finite element analysis can explain partially biomechanical mechanisms of meniscus which can provide theoretical guidance for clinical treatment of meniscus injury.
To explore the tensile mechanics and anatomical characteristics of the posterior hip capsule, and provide biomechanical and anatomical evidence for capsule repair in total hip replacement.
Six bone-capsule-bone specimens were obtained from posterior hip joint of fresh frozen cadavers. The maximum strain, load, elastic modulus and load strain curves of the capsule ligament complex specimens were recorded by Instron Universal Material Testing Machine. Twelve cadaveric hip specimens were dissected to the capsule. The tensile strain of normal capsule and conventionally reconstructed capsule at 90 degrees of hip flexion were documented. The suture area of the posterior capsule was divided into nine sections, and the thicknessof different sections was measured and compared. NSC 309132 ic50 Posterior capsule of the cadavers was repaired in conventionally way and anatomical way separately and simulated rehabilitation was conducted. The effect of rehabilitation on the repaired capsule was observed.
The load-strain curve of caps is thinnest at (1.42± 0.02) cm proximal to the femoral insertion, and sutures should be avoided here. After simulating rehabilitation, avulsion occurred in the lower part of the posterior capsule repaired conventionally (10/12), and the anatomically repaired capsule remained intact.
The lower part of conventionally repaired capsule is overstretched and tends to fail. Anatomically repaired capsule conforms to tensile mechanics and is helpful to reduce the failure rate of repair.

To analyze the clinical application value of adjustable skin retractor in large area of limb wound defect in children.
From January 2017 to January 2019, 11 children including 9 males and 2 females, aged 4 to 12 (8.3±2.7) years old with severe lower extremity wound defects were treated with adjustable skin stretch and closure device, all of them were unilateral lower extremity large area wound defects, including 4 cases of limb skin defect caused by traffic accident, 3 cases of failure to close after osteofasciotomy and decompression, 3 cases of plate exposure after internal fixation of lower extremity fracture and 1 case of ischemic necrosis after debridement and suturing of skin avulsion. The width of the wound was (5.6±1.2) cm and the length was (7.0±1.6) cm. VSD negative pressure drainage and expanded suture were used in all the patients. Four of them had been treated with free skin graft and two had been treated with local flap transfer. The graft or flap operation failed, and the effect of the early treatment was not good.
After 5 to 14 (10.5±2.6) days of continuous traction, the wound was closed and no skin grafting or flap repair was performed. No complications such as poor blood supply, skin infection and necrosis, peripheral sensory disturbance occurred. All 11 patients were followed up for 3 to 18 (8.9±3.8) months. The wound edge skin was linear healing with slight scar.
It is in accordance with Wolff's law and the concept of natural tissue reconstruction to treat large-scale limb wound defects in children with adjustable skin stretch and closure device, which provides an effective method for the treatment of limb skin and soft tissue defects in children.

To explore the risk factors of osteonecrosis of femoral head after internal fixation of femoral neck fracture in young patients, to describe the quality of life of patients with surviving femoral head, and to quantify the predictive factors.
From January 2013 to December 2016, 172 patients (174 hips) with femoral neck fracture treated by closed reduction and cannulated screw internal fixation were selected for retrospective analysis. The general data of the patients were summarized, including age, gender, body mass index, trauma mechanism, trauma operation interval, trauma season and whether the internal fixation was removed. The imaging data included the Garden classification and Pauwel classification of fractures, femoral head retroversion angle, postoperative fracture reduction, screw distribution. Single factor analysis and multi-factor Logistic regression analysis were carried out to explore the risk factors of femoral head necrosis and internal fixation failure. The patients who survived the internama mechanism of fracture could be used as the predictors of MCS.This article is part of a series in Nursing Older People exploring the nursing care of people living with advanced dementia. When someone with advanced dementia can no longer communicate verbally and has limited movement, activities they once enjoyed may no longer be possible. This limits opportunities for self-realisation and can lead to a preoccupation in advanced dementia care about the routines associated with the maintenance of comfort and nourishment, at the expense of contentment and moments of fulfilment. Such a narrow focus can lead to changes in behaviour, indicating boredom, frustration and distress. Yet there are opportunities for a more creative approach to activity that can be adapted to the person's changing needs and the human desire to feel connected and engaged. Examples of these evidence-informed, creative interventions for people living with advanced dementia care include music, doll-focused activity, animal-assisted interventions, multisensory experiences such as Namaste Care and complementary therapies.
