M83.9
Adult osteomalacia, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Adult osteomalacia, classified under ICD-10 code M83.9, is a condition characterized by softening of the bones in adults. This softening occurs due to a deficiency of vitamin D, calcium, or phosphate, leading to weakened bones that are more susceptible to fractures and deformities. Unlike osteoporosis, which involves loss of bone tissue, osteomalacia involves inadequate mineralization of the bone matrix, resulting in bones that are soft and fragile. Recognizing the signs and understanding potential causes are essential steps toward managing this condition effectively.
Causes & Symptoms
Clinical Causes: Vitamin D deficiency, often resulting from limited sun exposure or inadequate dietary intake Malabsorption syndromes, such as celiac disease or inflammatory bowel disease, impairing nutrient absorption Chronic kidney disease, affecting phosphate levels and vitamin D metabolism Certain medications, including anticonvulsants and corticosteroids, that interfere with vitamin D synthesis or calcium metabolism Liver diseases that impair vitamin D activation Hypocalcemia due to various underlying health issues Age-related decline in vitamin D synthesis and calcium absorption
Key Symptoms: Bone pain, commonly in the hips, pelvis, and legs Muscle weakness and fatigue Difficulty walking or a waddling gait Tenderness over affected bones Increased tendency to fracture, especially in the ribs, hips, and long bones Postural abnormalities, such as kyphosis (hunchback)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of adult osteomalacia involves a thorough evaluation, including medical history, physical examination, and laboratory tests. Blood tests often reveal low levels of vitamin D, calcium, and phosphate, along with elevated alkaline phosphatase levels. Imaging studies, such as X-rays, may show signs of bone demineralization and deformities. In some cases, bone biopsies are performed to confirm the diagnosis, especially when other conditions like osteoporosis are suspected.
Treatment Protocols: Management of adult osteomalacia focuses on correcting the underlying deficiency and restoring normal mineralization of bones. Treatment strategies may include:
