M43.15

Clinical Causes: Congenital defects in the vertebrae that predispose to slippage Degenerative changes associated with aging, leading to weakening of the spinal structures Traumatic injuries resulting from accidents or fractures Stress fractures due to repetitive strain, common in athletes Isthmic spondylolisthesis, where a defect in a part of the vertebra called the pars interarticularis causes instability Spondylolysis, or a defect or stress fracture in the vertebra Severe degenerative disc disease causing instability Spinal tumors or infections influencing the structural integrity of the vertebrae

Key Symptoms: Localized back pain that worsens with activity or certain movements Muscle tightness or stiffness in the mid-back or lower spine Radiating pain, numbness, or tingling sensations in the legs or buttocks Difficulty standing or walking for extended periods Loss of flexibility or weakness in the back In severe cases, symptoms of nerve compression such as bowel or bladder dysfunction

Diagnosis Path: X-ray: Often the first imaging test used to visualize vertebral alignment and the extent of slippage Magnetic Resonance Imaging (MRI): Provides detailed images of soft tissues, nerve roots, and spinal cord to assess nerve compression Computed Tomography (CT) scan: Offers a more detailed view of bony structures and any congenital anomalies or fractures

Treatment Protocols: Conservative Management: Rest and activity modification to reduce strain on the spine Physical therapy focusing on strengthening the core muscles to support the spine Pain medications such as NSAIDs (non-steroidal anti-inflammatory drugs) to alleviate discomfort Bracing or orthotic devices to stabilize the spine Epidural steroid injections to reduce inflammation and nerve pain Surgical Intervention: Decompression surgery to relieve nerve pressure Spinal fusion to stabilize the slipped vertebra and prevent further slippage In rare cases, corrective osteotomy or other spinal reconstructive procedures
