Lower limb pain in thalassemia.

Area of Science:

• Hematology
• Orthopedics
• Pain Management

Background:

• Homozygous beta-thalassemia is a severe inherited blood disorder.
• Patients with beta-thalassemia can develop complications affecting various organ systems.
• Lower limb complications in these patients are not well-characterized.

Purpose of the Study:

• To investigate the prevalence and types of lower limb disturbances in patients with homozygous beta-thalassemia.
• To characterize the different patterns of pain experienced by these patients.

Main Methods:

• A cohort of 67 patients with homozygous beta-thalassemia was assessed.
• Patients reporting lower limb complaints were further evaluated.
• Pain patterns were categorized, and intraosseous pressure was measured in some patients.

Main Results:

• Thirty-six out of 67 patients reported lower limb complaints.
• Four distinct pain types were identified: ischemic crampy muscle pain (12 patients), postural pulsating pain (18 patients), pain due to microfractures (4 patients), and synovitis from hemosiderosis (2 patients).
• High intraosseous pressure was noted in a significant number of patients.

Conclusions:

• Lower limb pain is a common issue in homozygous beta-thalassemia.
• Multiple pain mechanisms, including ischemia, high intraosseous pressure, hemosiderosis-induced synovitis, and microfractures, contribute to these disturbances.
