With regard to the case study you were assigned: Use the Episodic/Focused SOAP Template and create an episodic/focused note about the patient in the case study to which you were assigned using the episodic/focused note template provided in the Week 5 resources. Provide evidence from the literature to support diagnostic tests that would be appropriate for each case. List five different possible conditions for the patient’s differential diagnosis and justify why you selected each.

Episodic/Focused SOAP Note: Patient Case Study

Subjective:
The patient, Mr. X, a 45-year-old male, presents to the clinic complaining of persistent lower back pain for the past three months. He describes the pain as a dull ache that intensifies with movement, specifically bending forward or lifting heavy objects. He denies any recent trauma or injury to his back. Additionally, he reports occasional numbness and tingling sensation radiating down his leg occurring during prolonged sitting and relieved by walking. There is no associated weakness or urinary dysfunction.

Objective:
Physical examination reveals tenderness over the lumbar spine, primarily at the L4-L5 and L5-S1 vertebral levels. Straight-leg raise test elicits pain on the right side at approximately 60 degrees. Range of motion of the lumbar spine is limited, with increased pain during flexion. Motor strength and reflexes in the lower extremities are intact. No abnormal gait or lower limb atrophy is observed.

Assessment:
Based on the patient’s history and physical examination findings, several possible conditions can be considered for the differential diagnosis:

1. Lumbar Disc Herniation:
Lumbar disc herniation can cause lower back pain, radiating leg pain (sciatica), and neurological symptoms like numbness and tingling. The positive straight-leg raise test further supports the possibility of nerve root compression. To confirm the diagnosis, magnetic resonance imaging (MRI) of the lumbar spine is the gold standard, providing detailed visualization of the intervertebral discs and identifying any disc herniation or nerve compression.

2. Lumbar Spinal Stenosis:
Lumbar spinal stenosis typically presents with pain in the lower back and radiating leg pain, which often worsens with walking or standing and improves with sitting or forward bending. The patient’s symptoms of relief with walking and exacerbation with sitting align with this condition. Imaging studies such as MRI or computed tomography (CT) can help visualize the narrowing of the spinal canal and confirm the diagnosis.

3. Degenerative Disc Disease:
Degenerative disc disease is characterized by the deterioration of the intervertebral discs, leading to lower back pain and possible radiating leg pain. Physical examination findings of tenderness around the lumbar spine, limited range of motion, and pain with flexion align with this condition. MRI can be used to assess the integrity and degeneration of the discs, supporting the diagnosis.

4. Sacroiliac Joint Dysfunction:
Sacroiliac joint dysfunction can cause lower back pain that may radiate into the buttocks and thigh. The patient’s localized tenderness over the lumbar spine and limited range of motion indicate possible involvement of the sacroiliac joint. Diagnostic tests such as provocative maneuvers (e.g., FABER test) and ultrasound-guided injections can help confirm the diagnosis.

5. Muscular Strain:
Muscular strain is a common cause of lower back pain, often resulting from activities that involve heavy lifting or sudden movements. The patient’s reported exacerbation of pain with movement and physical examination findings of tenderness support this possibility. Imaging studies are generally not necessary, as the diagnosis is clinical.

In summary, Mr. X presents with chronic lower back pain, radiating leg pain, and associated neurological symptoms. Differential diagnoses to consider include lumbar disc herniation, lumbar spinal stenosis, degenerative disc disease, sacroiliac joint dysfunction, and muscular strain. Diagnostic tests such as MRI, CT, and provocative maneuvers can be employed to confirm or rule out these conditions, based on the individual patient’s presentation and clinical findings.
