The aim of this study was to consider at 2 years follow-up the functional outcome of femoral fracture in osteoporotic elderly treated with a surgical procedure followed by daily assumption of teriparatide, an anabolic agent increasing bone mineral content, density and strength.
They received daily subcutaneous teriparatide (20 microg) per day for 18 months, 1g of calcium and 800 UI of vitamin D3 daily as oral supplementation from day 15 by operation. All the patients repeated: xrays of affected segment at 2, 4, 6 months; biochemical bone markers 1, 3, 6, 12, 18 and 24 months; DEXA at first and second year. The evaluation of the quality of life was evaluated in terms of recovery of walking, need of re.operation, occurance of new fracture and with a questionnaire.
Lumbar and contralateral femoral BMD were increased after 12 months and maintained at 24 months. At 2 years follow-up all patients live, walk in autonomy without or with stick and none of them have needed a re-operation or was afflicted by new vertebral or non vertebral fracture.
Osteoprotegerin (OPG) is expressed by osteoblasts and functions as a decoy receptor that is able to control and to regulate osteoclastogenesis and therefore to prevent bone resorption. The objectives of our study were: to investigate OPG serum levels in shaft fractures non-union compared to controls; to assess the use of OPG as a marker for the early identification of fracture non-unions.
