User Assessment of a Novel Suspension for a Wheelchair-A Prospective, Randomized, Double Blind Trial.

Background: Many Wheelchair users experience adverse effects specific to their situation, some of which might be avoided if suspension systems are integrated into the wheelchair.

Objectives: Our study aimed to compare the user experience using a novel wheelchair suspension system with normal wheels. We tried to quantify the user feelings and impressions while using the different wheels.

Trunk kinematic, kinetic, and neuro-muscular response to foot center of pressure translation along the medio-lateral foot axis during gait.

Footwear devices that shift foot center of pressure (COP), thereby impacting lower-limb biomechanics to produce clinical benefit, have been studied regarding degenerative diseases of knee and hip joints, exhibiting evidence of clinical success. Ability to purposefully affect trunk biomechanics has not been investigated for this type of footwear. Fifteen healthy young male subjects underwent gait and electromyography analysis using a biomechanical device that shifts COP via moveable convex elements attached to the shoe sole.

Congenital pseudoarthrosis of the clavicle: Should we reconsider timing and fixation method?

Background: Congenital pseudoarthrosis of the clavicle (CPC) is rare and may require treatment, usually because of an unacceptable appearance or occasionally because of pain in an adolescent patient. Spontaneous union is unknown, and consequently any desired union requires open reduction and bone grafting. Many authors recommend performing the operation at the age of 3-5 years and using different fixation methods.

[HAND INJURIES IN ROCK CLIMBERS].

Rock climbing, whether practiced in nature on cliffs and boulders or indoors on walls made of resin and wood, has gained tremendous popularity in recent decades. More people are exposed to injuries associated with the unique biomechanical forces of rock climbing. A series of repetitive high torque movements of the upper limbs are needed to ascend a wall or rockface.

[TREATMENT FOR OSTEOARTHRITIS OF THE KNEE].

Osteoarthritis is the most common joint disorder in the world and its incidence is rising. In Western populations it is one of the most frequent causes of pain, loss of function and disability in adults. The estimated lifetime risk for knee osteoarthritis is approximately 40% in men and 47% in women.

Can orthopedic surgeons help create a better head start for osteoporosis treatment after hip fracture?

Background: Treatment for osteoporosis in the community in patients who were operated for hip fracture appears to be suboptimal at best. Evidence regarding treatment beyond the 1st year after surgery is scarce. We examined the association between discharge recommendations for treatment of osteoporosis in patients suffering from hip fractures and treatment beyond the 1st year.

Intrauterine fetal death of one twin of diamnionic twins is associated with adverse perinatal outcome of the co-twin.

Objective: To determine whether intrauterine fetal death (IUFD) of one twin of diamnionic twins after 22 weeks of gestation is associated with adverse perinatal outcome to the co-twin.

Method: A retrospective case-control study (n = 4070), including all twin births delivered between the years 1988 and 2010, was conducted. Perinatal outcome of the co-twin in diamnionic pregnancies complicated by IUFD were compared with the first twin from a pair of live-born diamnionic twins.
