Medicines for Spondylolisthesis

What it is

Spondylolisthesis is a condition in which one of the bones (vertebrae) of the spine slips forward out of position over the vertebra below it. It most commonly occurs in the lower back (lumbar spine). The degree of slip varies, and so do the symptoms — many people with a mild slip have few or no symptoms, while others have back pain and, if the slip narrows the space for the nerves, symptoms in the legs. There are different causes: it can result from a small stress fracture or defect in part of the vertebra (common in younger, active people, and in certain sports involving repeated back-bending); from age-related wear and degeneration of the spine (degenerative spondylolisthesis, more common in older people); and, less commonly, from other causes. Symptoms, when present, can include lower back pain (often worse with activity, standing or bending backwards, and eased by rest), stiffness, tight hamstrings, and, if the nerves are affected, pain, numbness, tingling or weakness in the legs (and, rarely, symptoms from significant nerve compression). It is diagnosed with imaging (such as X-rays, which show the slip). Most spondylolisthesis is managed without surgery, and many people do well with conservative treatment.

How it is treated

Management depends on the symptoms, the degree of slip, the cause, and the person, and most cases are managed conservatively (without surgery). For the many people with a mild slip and manageable symptoms, non-surgical treatment is the mainstay: physiotherapy is central — including exercises to strengthen the core and back muscles, improve flexibility (particularly the hamstrings), and support the spine, along with advice on posture, activity and pacing — which helps many people manage their symptoms and stay active. Simple pain relief and activity modification (avoiding activities that clearly worsen it, while staying active) help, and, in younger people with a stress-fracture cause, a period of activity modification (and sometimes bracing) may be advised to allow healing. Where there are leg symptoms from nerve involvement, these are assessed and managed. Surgery is considered in a minority of cases — for example a significant or progressing slip, severe or persistent symptoms not responding to conservative treatment, or significant nerve compression causing worsening leg symptoms — and can involve decompressing the nerves and/or stabilising (fusing) the spine. Regular review monitors symptoms, and, in some (particularly younger people), the slip is monitored over time. The reassuring message is that spondylolisthesis is often a manageable condition — many people have few symptoms or do well with physiotherapy and conservative treatment — with surgery reserved for significant or unresponsive cases.
