Spondylolisthesis is the most likely diagnosis for the 65-year-old lady who presents with backache and the described characteristics in the radiograph of the spine. This condition involves the displacement of a vertebra and is often associated with aging-related degenerative changes. The key points supporting this diagnosis include:
- Definition: Spondylolisthesis refers to the forward or backward displacement of a vertebra over the one below it, which can lead to pain and reduced function.
- Symptoms: Typical symptoms include lower back pain, which may radiate to the legs, and this condition is common in older adults due to degenerative processes.
- Radiographic Features: X-rays often show the misalignment of vertebrae. The image associated with the question likely depicts this characteristic slippage.
- Differential Diagnosis: While osteoporosis, spondylolysis, and discitis could present with back pain, the radiographic indication of vertebral misalignment aligns more closely with spondylolisthesis.
