Treatment of osteoporotic fractures leads to significant challenges for the surgeon, including poor implant fixation related to low bone quality and compromised capacity of fracture healing. This article reviews the osteosynthesis and arthroplasty results in the surgical treatment of proximal femur, proximal humerus and wrist fractures to define the current options to decrease failure in fragility fracture management.

Osteoporosis is a skeletal disorder characterized by compromised bone strength predisposing to an increased risk of fracture. The most frequent sites of fragility fractures are the hip, the distal radius, the spine, the proximal humerus, and the ankle. In most cases, a surgical approach with subsequent rehabilitative treatment is required. The general aims of rehabilitation are to increase functioning and improve patients' activities, participation level, and quality of life.

Osteoporosis is a skeleton disease characterized by low bone mineral density and deterioration of bone tissue, resulting in an increased risk of fragility fracture. Osteoporotic vertebral fractures are recognized as a significant health problem particularly in older people with an impact on the quality of life, mobility and mortality. ⋯ The exercise protocols, designed specifically for individuals with vertebral fracture, should include postural correction, trunk and lower extremity muscle strengthening, balance exercises and falls prevention program. The aim of this short communication is to examine the rationale of a rehabilitation protocol after a vertebral fracture.

Osteoporosis is predominantly a condition of the elderly with a consequent increase in bone fragility and susceptibility to fracture. A number of clinical as well as biological studies have been pivotal in providing us with an understanding of the pathophysiology of this condition. This article discusses the current concepts of age-related osteoporosis.

The biomechanical understanding of increasing anterior column load with progressing kyphosis leading to subsequent vertebral compression fracture (VCF) established the basic rationale for kyphoplasty. The lumbar spine can support an effort of 500 kg in the axis of the vertebral body, and a bending moment of 20 Nm in flexion. Consequently, if this effort is forward deviated of only 10 cm, the acceptable effort will be reduced to 20 kg so it is important to restore the vertebral anterior wall after a VCF: the authors describe the biomechanical modifications in the spine after kyphoplasty.
