A nurse is assessing an older adult client who has osteoporosis. Which of the following spinal deformities should the nurse expect to find in this client?

A. Kyphosis: Osteoporosis weakens vertebrae, leading to compression fractures that cause a forward curvature of the thoracic spine. This results in a hunched posture known as kyphosis, which is a classic finding in older adults with advanced osteoporosis. B. Ankylosis: Ankylosis refers to joint stiffness or immobility due to abnormal fusion of bones, often seen in conditions like ankylosing spondylitis. It is not a typical manifestation of osteoporosis. C. Scoliosis: Scoliosis is a lateral, S-shaped curvature of the spine usually developing in adolescence. It is not directly associated with osteoporosis, though vertebral fractures can sometimes exaggerate spinal misalignment. D. Lordosis: Lordosis is an excessive inward curvature of the lumbar spine, often related to obesity, pregnancy, or muscular imbalance. It is not the spinal deformity typically expected in clients with osteoporosis.
