ICD-10: M99.74

ICD-10 code M99.74 refers to "Connective tissue and disc stenosis of intervertebral foramina of the sacral region." This code is part of the broader category of biomechanical lesions, specifically focusing on conditions affecting the connective tissue and intervertebral discs that lead to stenosis, or narrowing, of the foramina in the sacral area of the spine.

Clinical Description

Definition of Stenosis

Stenosis in the context of the intervertebral foramina refers to the narrowing of the openings through which spinal nerves exit the spinal column. This condition can lead to nerve compression, resulting in pain, numbness, or weakness in the lower extremities, depending on the severity and location of the stenosis.

Connective Tissue Involvement

The connective tissue plays a crucial role in maintaining the structural integrity of the spine. In cases of M99.74, the connective tissue may become thickened or fibrotic, contributing to the narrowing of the foramina. This can occur due to various factors, including degenerative changes, trauma, or inflammatory processes.

Disc Pathology

The intervertebral discs act as cushions between the vertebrae and can also contribute to stenosis when they degenerate or herniate. In the sacral region, disc degeneration can lead to a reduction in disc height, which may further narrow the foramina and exacerbate nerve compression.

Symptoms and Clinical Presentation

Patients with M99.74 may present with a variety of symptoms, including:

• Radicular Pain: Pain that radiates along the path of the affected nerve, often described as sharp or shooting.
• Numbness and Tingling: Sensations of numbness or tingling in the lower back, buttocks, or legs.
• Weakness: Muscle weakness in the lower extremities, which can affect mobility and balance.
• Changes in Reflexes: Diminished or absent reflexes in the legs may be observed during a neurological examination.

Diagnosis

Diagnosis of connective tissue and disc stenosis of the intervertebral foramina typically involves:

• Clinical Evaluation: A thorough history and physical examination to assess symptoms and neurological function.
• Imaging Studies: MRI or CT scans are commonly used to visualize the spine and assess the degree of stenosis, disc degeneration, and any associated pathologies.

Treatment Options

Management of M99.74 may include:

• Conservative Treatments: Physical therapy, pain management with medications, and lifestyle modifications.
• Interventional Procedures: Epidural steroid injections or nerve blocks may be considered to alleviate pain and inflammation.
• Surgical Options: In severe cases, surgical intervention such as decompression surgery or laminectomy may be necessary to relieve nerve compression.
