Introduction: Between the elderly affected by femoral neck or diaphyseal fractures are emerging few serious complications as delate union, instability of osteosynthesis, re-fracture or periprosthetic fracture. In addition the co-morbidity elevate ulteriorly the risks of the new operation which is often impossible or refused. Recently it has been recommended to orthopaedic surgeons the managment and treatment of osteoporosis.

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.

Materials and Methods: 21 compliant female between 63 and 94 years-old presenting a femoral fracture were recruited. Before operation they undergone to a routinary instrumental examins completed by bone metabolism screening. This was constituted by biochemical bone turnover markers, standard radiograms of dorsal and lumbar spine. Lumbar and contralateral femoral BMD was measured by DXA during hospitalization before the assumption of anabolic agent.

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.

Results: eleven lateral femoral neck fracture treated with endomedullary nail, six medial femoral neck fracture treated with cemented endoprosthesis, four periprosthetic fracture of the femur treated with plaque and screws. The healing was detected with radiograms before 4th month. The vitamin D was at lower levels at admission but the supplementation was sufficient to normalize. The other biochemical variables of bone formation and resorption peaked within the consolidation process then remained normalized for two years.

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.

Conclusions: The clinical relevance of the present study is the significant improvement of functional outcome and quality of life after femoral fracture in osteoporotic elderly with post-operative assumption of anbolic agent as Teriparatide.
