Diabetes can alter physical signs in cervical spondylotic myelopathy (CSM). Diabetic patients may show hyporeflexia and a positive Babinski sign, aiding diagnosis.
Area of Science:
- Neurology
- Orthopedics
- Endocrinology
Background:
- Cervical spondylotic myelopathy (CSM) is a common spinal cord compression condition.
- Diabetes can cause neuropathy, potentially altering neurological examination findings.
- Few studies have investigated how diabetes affects the presentation of CSM.
Purpose of the Study:
- To compare the presenting neurological signs and symptoms of surgically treated CSM patients with and without diabetes.
- To evaluate the impact of diabetes on clinical outcomes after CSM surgery.
Main Methods:
- Retrospective study of 438 patients surgically treated for CSM.
- Comparison of neurological signs, symptoms, and outcomes between 79 diabetic and 359 non-diabetic patients.
- Preoperative modified Japanese Orthopaedic Association (mJOA) scores and specific reflex assessments were analyzed.
Main Results:
- Diabetic patients were older and had lower preoperative mJOA scores.
- A higher incidence of hyporeflexia and a positive Babinski sign was observed in diabetic patients.
- Surgical outcomes, measured by mJOA improvement, were comparable between groups.
Conclusions:
- Diabetes can alter the typical physical findings in cervical spondylotic myelopathy.
- Recognizing these differences, such as hyporeflexia and Babinski sign, may improve diagnostic accuracy for CSM in diabetic individuals.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
