What is the treatment plan for a patient with glycosuria and lumbar spine issues, including disc bulges and facet arthrosis?

Treatment Plan for Patient with Glycosuria and Lumbar Spine Pathology

The treatment plan for this patient should prioritize management of both the glycosuria (likely indicating diabetes) and the progressive lumbar spine pathology with severe central canal and foraminal narrowing.

Diabetes Management

• Immediate diabetes workup is necessary given the significant glycosuria (glucose 500) even with negative ketones. This likely represents uncontrolled diabetes that requires prompt intervention 1.

• Blood glucose monitoring should be ordered with results made available to all members of the healthcare team to guide management 1.

• Insulin therapy should be initiated if persistent hyperglycemia is present (threshold of 180 mg/dL), with a target glucose range of 140-180 mg/dL to balance glycemic control with safety 1.

• Scheduled subcutaneous insulin with basal, nutritional, and correction components is preferred for achieving and maintaining glucose control 1.

• Individualized glycemic targets may be appropriate based on the patient's age and comorbidities, with less stringent targets potentially warranted given the severe spinal pathology 1.

Lumbar Spine Management

Imaging Assessment

• MRI findings demonstrate significant pathology requiring intervention:

  • L5-S1: Disc bulge eccentric to left with moderate facet arthrosis causing severe central canal narrowing (worsened since 2020) and severe left foraminal narrowing 1
  • L4-L5: Eccentric disc bulge to right with moderate facet arthrosis causing moderate right and mild left narrowing 1
  • Lumbar levoscoliosis (15 degrees)

• CT lumbar spine without contrast may be useful for preoperative planning to delineate osseous margins and aid in trajectory planning for hardware fixation 1.

Treatment Approach

1. Initial conservative management (unless neurological deficits are present):

   • NSAIDs for pain control and potential anti-inflammatory effect on facet arthrosis 1, 2
   • Physical therapy focused on core strengthening and spine stabilization 1
   • Facet joint injections with corticosteroids may be considered for facet arthrosis-related pain 1, 2

2. Surgical intervention is indicated due to:

   • Severe central canal narrowing at L5-S1 (worsened since 2020)
   • Severe left foraminal narrowing at L5-S1
   • Moderate right foraminal narrowing at L4-L5
   • Progressive worsening of findings compared to previous imaging 1

3. Recommended surgical approach:

   • Posterior lumbar fusion with pedicle screw fixation at the affected levels (L4-L5, L5-S1) 1
   • Interbody fusion technique (TLIF or PLIF) to address the disc bulges and restore foraminal height 1
   • Decompression of the central canal and neural foramina to address the severe narrowing 1

4. Rationale for fusion over decompression alone:

   • Presence of moderate facet arthrosis at both levels increases risk of post-decompression instability 3, 4
   • Progressive nature of the pathology suggests ongoing degenerative process 1
   • Facet arthrosis is present in nearly 100% of patients over age 60, and is highly prevalent at L4-L5 (79%) and L5-S1 (59%) 4

Perioperative Considerations

• Diabetes management during hospitalization:

  • Clear identification of diabetes in the medical record 1
  • Regular blood glucose monitoring with target range of 140-180 mg/dL 1
  • Adjustment of insulin regimen based on surgical stress and NPO status 1

• Osteoporosis screening should be considered given the risk of poor bone quality affecting surgical outcomes 1

• Fall risk assessment is important given the spinal pathology and potential for neurological compromise 1

Post-Surgical Care

• Diabetes education and self-management training should be provided 1

• Physical therapy for post-surgical rehabilitation and core strengthening 1

• Regular follow-up imaging to assess fusion status and hardware position 1

• Long-term diabetes management with appropriate medication adjustments and lifestyle modifications 1

Common Pitfalls to Avoid

• Delaying diabetes management while focusing only on spine pathology can lead to poor surgical outcomes and increased perioperative complications 1

• Underestimating the contribution of facet arthrosis to the patient's pain syndrome; facet arthrosis can be a significant source of pain even with minimal radiographic changes 5

• Performing decompression without fusion in the setting of facet arthrosis can lead to post-surgical instability and failed back syndrome 1, 3

• Inadequate perioperative glycemic control increases risk of surgical site infections and poor wound healing 1
