Abstract:
Osteomalacia is a disorder in which the mineralization of the organic matrix of the skeleton is defective. Proximal muscular weakness is a common symptom of osteomalacia. A 27-year-old woman reported the gradual onset of gait disturbance and bone pain in the thigh. Her height shortened during 10 months. On neurological examinations, proximal muscular weakness of the extremities was disclosed. Serum phosphorus was 1.8 mg/dl (normal 2.5~4.5), alkaline phosphatase was 1045 IU/L (normal 70~290), and 1,25 (OH)2 vitamin D3 was 18 pg/ml (normal 20~60). On roentgenography, multiple pseudofracture lines of the rib and erosion of the head of the right femur were demonstrated. A bone scan showed multiple hot spots on the ribs and right femur. She was medicated with calcitriol and phosphorus and she recovered most of her strength and experienced decreased bone pain after 3 months. We report a case that confirms osteomalacic myopathy by an endocrinological test in patients who experienced gradual proximal muscular weakness and bone pain.
