Multiple atraumatic osteoporotic vertebral fractures: Unusual cause of pain i...Apollo Hospitals
Secondary osteoporosis may not be detected early, and thus the condition remains clinically silent until the patient presents with multiple atraumatic compression fractures. It is devastating for a young patient to develop multiple vertebral fractures in view of the associated morbidity and mortality. To decrease the risk of additional fractures and preserve the quality of life in these patients, interventions should be initiated early. Hence, it is important to consider multiple osteoporotic vertebral fractures as a complication in any patient on prolonged steroid therapy.
Regenerative medicine is now an recognized specialty which has evolved from degerative diseases of Orthopaedic Surgery.Orthobiologics is a current terminology for the application of various cells, cytokines, growth factors.Busy people find it to update and this is an update.

We report the 11-year follow-up of a premenopausal woman with osteogenesisimperfecta (OI) who
was treated with alendronate. A 41-year-old Japanese premenopausal woman with OI type I who had
frequently experienced painful fragility fractures consulted our clinic because of chronic back pain associated
with spinal osteoporosis. She had undergone heart surgery (aortic valve replacement) because of aortic
regurgitation 5 years before her first consultation with our clinic. After surgery, she began taking warfarin (3
mg/day), and this treatment was continued during our follow-up period. She was treated with alendronate (5
mg/day or 35 mg/week) for 11 years. The patient’s urinary cross-linked N-terminal telopeptides of type I
collagen and serum alkaline phosphatase levels decreased, while the bone mineral density of her lumbar
spine (L2–L4) increased, as measured using dual energy X-ray absorptiometry. The serum calcium and
phosphorus levels stayed within the normal ranges. Three non-vertebral fractures occurred at the hip, ankle,
and ring finger during the 11-year treatment period, but no adverse effects were observed. Thus, the present
case report showed the long-term outcome and safety of alendronate treatment in a premenopausal woman
with OI type I.
Musculoskeletal Complications of Cancer and its TreatmentsInsideScientific
Cancer frequently associates with the occurrence of cachexia, a debilitating syndrome responsible for reduced tolerance to anticancer therapies, as well as increased morbidity and mortality. Dr. Bonetto's group reported that animals bearing cancers not only show reduced skeletal muscle mass and strength, but also dramatic bone loss, despite the absence of bone metastases. Their latest findings revealed that muscle and bone depletion may also occur as a direct consequence of anticancer treatments (i.e., chemotherapy). There is now substantial agreement on the fact that abnormalities of the so-called ‘muscle-bone crosstalk’ may contribute to the onset of cachexia secondary to cancer or chemotherapy. Clinical and experimental observations also suggest that pharmacological bone preservation may concurrently benefit muscle mass in animal models, burn patients and osteoporotic women.
In this webinar Dr. Bonetto will present evidence that bone preservation directly impacts muscle size and function in cachexia, thus also contributing to unraveling novel pathogenetic mechanisms and opening new avenues for treatment.
Osteoarthritis is the most common disease of women after menopause. There are many factors to develop the disease. Hormones play important role to in this context. The objective of the present study is to determine whether the levels of thyroid and sex hormones are associated with osteoarthritis (OA) in postmenopausal women. Forty three patients suffering from OA and twenty control subjects were included in this study. Thyroid and sex hormones were measured in the serum by enzyme linked immunosorbent assay technique. In OA patients serum estrogen levels were low as compared to control subjects(p<0.001), but these patients did not show any significant change in thyroid hormones and progesterone hormone levels when compared with control subjects. The findings suggest that estrogen deficiency after menopause may contribute to develop OA in postmenopausal women.
